Scientific description of the phone. Mobile phone: the history of creation, the main functions and characteristics of modern devices

The life of a modern person is closely related to mobile phones, and this has a lot of confirmation. Imagine, for example, the situation is that your favorite, indispensable and gem smartphone you randomly left at home. How do you feel at this moment? At least, uncomfortable, is it not true? However, there were times when people had no phones at all, not only mobile, but also stationary. How did they do without them? Read in our article.

Life without phones

Some 200 years ago, people did not know what phones are. Previously, whistling, gong, ringing bells and drum battle were used to transfer messages.

However, all these methods were imperfect.

By the way, to convey the signal as far as possible, it was necessary to create intermediate items on which people were on duty. The sound in this case came to the addressee on the chain. We all understand that it was a very long process. Of course, it was possible to solve this problem, for example, transmit information through water and metal. In this case, the signal would be spread faster and looked much later. But for some reason they did not do, at least, everywhere.

The invention of the first phone

We traditionally communicate with the name of the American inventor Alexander Bella. The famous researcher actually took direct participation in the development of the revolutionary apparatus. However, other people have played a crucial role in creating the first phone.

In 1860, Antonio Meucci's naturalist published an article in the Italian newspaper New York, which spoke about his invention capable of transmitting sounds on electrical wires. The Meuchchic apparatus called Teletrofono. In 1871, he decided to patentroofono, however, due to financial problems, it was not possible.

A year later, in 1861, the German physicist and the inventor Johann Philip flight at the meeting of scientists of the physical community demonstrated its "mobile phone". The device could transmit musical tones and human speech on the wires. The device had an original design microphone, a power supply (galvanic battery) and a speaker. The flight itself called the Telephon designed by them. In many sources of that time, it is argued that the first message that the physicist conveyed on his phone was the phrase "Das Pferd Frisst Keinen Gurkensalat" ("The horse does not eat cucumbers salad"). The absurdity of this information made it possible to make sure that the words were heard correctly, it follows from this that the transmitter worked as it should.

Despite all of these inventions, the laurels of the discoverer went to Alexander Grahem Bell.

So, on February 14, 1876, Bell filed a request to the Washington Patent Bureau, March 7, 1876, American received a patent. He called his device "talking telegraph". The Bella tube could pass over and receive a signal. There was no call in the telephone of the American scientist, it was invented a little later, in 1878, Thomas Watson. When someone called a subscriber, Telegraph began to whistle. The range of such a line did not exceed 500 meters.

Note that Alexander Bell for a long time was officially considered the inventor of the phone. And only on June 11, 2002, the US Congress in Resolution No. 269 transferred this status of Antonio Meucci.

Turning a speaking telegraph into a landline phone

Talking Telegraph Bella passed a lot of metamorphosis before turned into a modern smartphone.

So, in 1877-1878. American inventor Thomas Edison has improved the device. It introduced the induction coil into the scheme, and in the microphone replaced the coal coal rod coal powder (such microphones were used until 1980). This made a connection with a clearer and loud. Now phones, in contrast to public telegraphs, became household apparatus.

In 1878, the first telephone station in New Haven was also appeared. Next year, Paris took the relay. Since 1881, telephone exchanges began to open in Berlin, Riga, Warsaw. In Russia, namely - in Moscow and St. Petersburg, they appeared in 1882

It is worth noting that the first telephone stations were manual - the compound was carried out by a telephone. But in 1879, American engineers of Connol and McTowt invented an automatic switch. Now people could reach each other, just gaining a room.

Start XX century. It is marked by the present telephone boom. All over the world, there was an active construction of telephone stations, which by 1910 became more than 10 thousand, and long-distance lines serving more than 10 million phones.

It turns out that in just some half a century, the phone has passed the way from the unless dream of inventors and enthusiasts to the most massive phenomenon, allowing millions of people to communicate at a distance. From this time, mankind can no longer imagine life without this apparatus. But when did he ever turn into a smartphone?

The emergence of mobile phones. History of modern smartphone

In 1969, world leaders of the telecommunications market began to think about improving the wired apparatus. They wanted every subscriber to have their own room, which would be relevant not only in the country where was decorated, but also abroad. The graduate of the Stockholm Technical School ESTEN Malkitolo was one of the first to whom such an idea came to mind. However, for the practical implementation of the concept of meakitolo, powerful technologies were required, which appeared only in the 1980s.

Therefore, only in 1983, Motorola was able to release the world's first cell phone. Although experimental calls from the prototype were made in the 1970s.

It was a tube weighing about 0.8 kg and dimensions of 22.5x12,5x3.75 cm. The battery allowed to communicate as long as 35 minutes, but it was accumulated a little more than 10 hours. Of course, it is not compared with modern devices, but for that time it was a huge breakthrough.

Motorola has very quickly competitors who have become more advanced and intellectual models every time. So, over time, a calculator, alarm clock, calendar, camera and many other applications and functions appeared in the phone. In 2000 phones began to appear with the operating system, which turned them into personal computers. Today, with a smartphone, you can not only call a friend or send a message. For him, it is primitive. It can establish communication with satellites, make large-scale pictures, play music, not to mention reading books, watch movies and working in multitasking mode.

Then you could only dream about it. However, progress took his. It took a little more than 60 years to appear in the middle of the last century the device acquired the choice for us today. Consider a brief history of the emergence and development of a mobile cell phone, as well as cellular communication as a whole.

Go…

In 1947, the Bell Laboratories laboratory officially made a proposal to create a mobile phone. This date can be considered a reference point. It was then that an active work began on creating a new device.

However, the first mobile one was destined not in the walls of Bell Laboratories. The first prototype of a mobile cell phone was created by American company Motorola.. This happened in 1973. Engineer Martin Cooper became the creator of the device. The weight of the first cell phone was about 1 kg, dimensions: 22,5x12,5х3.75 cm. The device was absent. The phone's battery allowed it to work in standby mode up to 8 hours, and in a conversation mode - up to one hour. Charge the phone was needed long enough (about 10 hours). In 1984, the work model of the cell phone Dynatac 8000X was on sale. The price of the novelties was $ 3,995. However, despite this, thousands of wishing to acquire a new device were recorded in a queue for the purchase of the apparatus!

In the USSR, the first experimental sample of a cell phone was created in 1957, he weighed as much as 3 kg! Moreover, the apparatus was also attached to the basic station, which was associated with the city telephone network (GTS). However, after a year, the weight of the device was reduced to 0.5 kg.

The first cellular operator in the USSR appeared in 1991. The price of the phone, which then offered the company "Delta Telecom" was $ 4,000, including connection. The device weighed about 3 kg. A minute of conversation went by $ 1. At the same time, from 1991 to 1995, the number of subscribers of the company reached 10,000 people. In the Russian Federation, the first operator of cellular communication, working on the usual GSM technology today, appeared in 1994.

The number of cellular subscribers constantly and steadily grew. In 2009, about 190 million subscribers were registered in Russia. Of course, this is the number in our country, as well as around the world, today continues to grow.

There is no limit to perfection

Cell phone has been constantly improved from the moment of its creation. In 1993, the world's first cellular with built-in clock was released. After 3 years, the German company Siemens began producing devices with a voice recorder and a color display. True, there were only three colors on such displays. In 2000, devices with a built-in camera appeared on sale. It happened in Japan. At about the same time, telephones with a built-in MP3 player were sold. In 2001, the Java platform support appears in cell phones. This made it possible to install many different applications on the devices. Among them is the most famous instant messaging service - ICQ. The first mobile with the support of Bluetooth technology in 2002 was issued by Ericsson. This technology has given an opportunity to exchange various data between phones on a certain radio frequency (without wires). At the same time, the phones should be close enough to each other. Depending on the interference, the Bluetooth radius barriers ranges from 10 to 100 m. At the same time, a telephone supporting the EDGE technology appeared. She allowed to go out with the help of the phone to the Internet. And do it at a fairly high speed. The development of EDGE pushed the WAP technology earlier to the second plan. The latter allows you to go online at smaller speeds. At the same time you need to pay for the time of staying on the network, and not for the volume of viewed information. Implementation eDGE technology - The merit of the Finnish company Nokia.

List all new features that appear in the process of improving cell phones are long. The improvement process continues today. While you are reading this article, another unique device is already created in the world. For example, a telephone capable of typing the text entered by means of alone thoughts ("read" your thoughts and turn them into text). By the time of the release of such a device, it will be worth knowing and understand the already existing basic functions of mobile phones. Let us turn to their consideration.

25 basic functions

So, consider the most common features of modern mobile phones.

Phonebook . This feature For any mobile phone - the thing is necessary and mandatory. Available in all modern devices. Allows each telephone number to assign its unique name. For example, 8-888-888-88-88 - Ivan Petrov. Contacts can be saved in the memory of the phone, the additional memory card or the SIM card. Concepts such as "memory card" and "SIM-card" are considered in paragraphs 15 and 19, respectively.

In more advanced devices, it is possible to save many useful information For each contact ( electronic address, home and working telephone numbers, place of work, home address, etc.). In this case, the phone performs a full-fledged notebook function.

Call log . The function is extremely useful. It makes it easy to see where and when you called (or called you). Also using the call log, you can see the duration of any of your conversation. Today, this feature is present in each cell phone.

SMS (Short Message Service - Short Message Service) . The same is the same maintenance today, as the two previous ones. Allows you to transmit and receive short text messages in cellular networks. Today, this feature is present even in the cheapest models.

MMS (Multimedia Message Service - Multimedia Messaging Service). This feature allows you to transfer and receive multimedia messages (video, audio, pictures) from one phone to another. It should be noted that the size of the transmitted content is sufficiently limited. Most cellular operators in Russia and the CIS allow you to transfer to 300 kb of information in one MMS message. Today, the largest cellular operators allow sending SMS and MMS from their sites for free. Pay only only services for using the Internet.

Clock . Today, perhaps, it is impossible to meet a cell phone devoid of this function. Although, of course, if you want - everything is possible. After all, the phones are for every taste and color. The clock is useful, simple, the desired function. At the same time, no one forbids you to wear your favorite wristwatches.

Stopwatch . What makes it possible to do - clear from the name. Stopmakers in modern phones have quite high accuracy. The function is useful athletes. It may be useful to students during laboratory work.

Timer . The opposite of the stopwatch. Allows you to count the "Back" time, make the countdown. You choose some time interval and turn on the timer. At the end of this segment, the timer delivers a specific signal (sound, vibration).

Alarm clock . This feature can be used instead of an ordinary stationary alarm clock. Or as another, safety alarm clock. Very comfortable thing. Especially when you were visiting, and in the morning you need to wake up early.

The calendar . Useful feature. Often there is no ordinary calendar at the right moment. And you need to see what the day of the week, for example, April 10th. A couple of fast presses - and you know. Very comfortably.

Calculator . Most often, the phones are installed simple (not engineering) calculator. It is suitable for some rapid simple calculations. When you need to fold something, subtract, divide, multiply or take the percentage. The presence of this function can really come in handy. After all, the usual calculator does not always happen where he is needed now. Today this feature is present in almost any mobile phone.

Converter . Allows you to translate different quantities (units of volume, area, length, etc.) from some measurement systems to others. This includes the possibility of recalculating some currencies to others according to the course you know.

Radio . Lets absolutely free to listen to publicly available radio stations operating on FM frequencies. The desired function for those who want to constantly be aware of events. Who loves to listen to news and favorite programs on the radio.

Flashlight . It will be very useful when there is no conventional lantern at hand. And you will certainly need something to highlight somewhere. You can certainly highlight and bright displayed display. But the flashlight in this case is much better. Shines brighter, white light. Moreover, in contrast to the display, shines point, and not "smeared".

Photo, video camera . Useful feature. Present in most modern mobile phones. Sometimes there is no camera or camcorder at hand, and you urgently need to capture. Let even not in the best quality. Although you can argue about quality. There are phones in which the main emphasis is on the ample chamber capabilities. Such devices allow you to receive photos and videos. decent quality. Such phones are called camera phones. An example of a champion -. It is equipped with a camera for 8 million pixels. with LED flash; Maximum resolution for photo 3264x2448 Pix.

Memory card support . In cell phones, various information (your contacts, audio, video files, photos) can be stored in the memory of the device itself. However, most often the amount of this memory is very limited. Although there are devices with quite decent own memory. To expand memory, phones usually equip the connectors ("slots") for special memory cards (flash cards or "flash drives"). There are various types of memory cards. Today, in mobile phones, the MICROSD and MicroSDHC flash cards are most common. The first allow you to store up to 4 GB of information, the second - up to 32 GB.

MP3 player . For music lovers - the function is simply indispensable. Allows you to listen to the audio files on the phone (or on the inserted) audio files. Moreover, the most advanced telephone model in this regard will reproduce sound not only in MP3 format. They support AAC, WMA, WAV and some other formats. The devices in which the main focus is made on the increased quality of the sound of the sound are called "musical phones" (musical phones). An example of such a phone -.

Dictaphone . Useful feature. Imagine: You need to fix it, and write down - no time. Or just laziness. It is much easier and faster to press the "Record" button and save the desired audio file. Fix some conversation or conversation is very convenient. It will be worth this feature for musicians. You never know where inspiration comes to them. Included the voice recorder - wrote down the wrought music, a vocal party or a song. Quickly, simple, comfortable.

the Internet . Most modern phones allow you to go out global Network. The main options to get to the Internet today there are four. This is WAP, GPRS, Wi-Fi and 3G. Let's not stop in detail each of them. This is a separate big conversation. Note that GPRS is the most demanded today. Although this is not the fastest Internet access option. Technology WAP. In the form in which it exists today is not promising. Too expensive and slow. Moreover, you need to pay not for the scope of viewed information (as in the case of GPRS), but during your stay on the network. Wi-Fi will definitely not be an excess function in your device. It allows you to work on the Internet at high speed. However, Wi-Fi is needed special access points, so-called hot spot. They are paid and free. The latter are most often located in various public places. Where there is a constant cluster of people (cinemas, bars, cafes, etc.). It should be noted that their number in all major cities of Russia is growing. 3G is high-speed technology mobile access To the Internet, the so-called mobile communication of the third generation. Based on the definition, it is clear, the data transfer rate is even higher than in the case of Wi-Fi. This service In the Russian Federation is under development. Moreover, this development goes fairly rapidly. It is possible that the 3G function will soon be very popular among mobile phone users in our country.

"Multi-term" . Under this term is understood as the ability of the device at the same time working with two and more active SIM cards.

Each mobile operator for one purchased phone number gives you your SIM card. At the same time, you yourself choose the tariff for which you will further pay your mobile communications. Of course, each operator has its own conditions (rates for communication), its set of tariffs. It changes periodically. An understandable question arises: what is the actual function in question? And she is good because it allows you to simultaneously be in touch on two or even three different telephone numbers. After all, today there are phones that support three active "sim cards at once. At the same time, the rooms may relate to both different cellular operators and one. Accordingly, you get the opportunity to "play" with tariff plans. You can choose the most profitable option for communication. And to have with you in this case just one included mobile phone. An example of a phone with two active SIM cards.

Java support . This feature allows you to install various games and applications on the Java platform. For lovers to communicate through the ICQ instant messaging service - the item is mandatory. Moreover, "Asya" allows you to communicate many times cheaper than a short service sMS messages. Those who love to play on the phone in all sorts of racing, "shooting", "mini-quests", etc., without Java's support also do not do.

POSSIBILITY TO PC (DATA Cable) . Allows you to transfer various files from your mobile phone to a computer and vice versa. Today, phone manufacturers produce special programs for their devices. These programs allow you to make a lot of useful things with the phone. They are installed on your computer. Then connect the phone to the PC (using a special cable). Now you get the opportunity, for example, create backups Data from mobile. In addition, a number of other interesting features appear. The function is definitely useful.

IR port. Infrared port . Technology allows you to transmit data from one device to another. This happens by infrared light waves. Today, this technology is almost completely displaced by other, more perfect (Bluetooth and Wi-Fi).

Bluetooth . This technology allows you to share various information between mobile phones, PCs and other devices on a certain radio frequency. You should know that for such a exchange, the distance between devices should not exceed 10-100 meters (it depends on various interference and obstacles). A sufficiently convenient feature. There are in most modern mobile phones.

TV-tuner . TV on your mobile phone screen. In Russia, today this function is poorly developed. The reason is the high cost of receiving a high-quality signal. However, in the world of mobile communication, nothing is in place. It is possible that in the near future the situation will change. And with the development of new technologies, we will watch television programs on the screens of their phones. An example of such a phone -.

GPS. . Satellite navigation system. Allows with sufficient accuracy (accuracy of 1-2 m) to determine your location anywhere in the globe. Mobile phoneWith this feature and equipped with a special program, turns into a navigator. Useful travel and long-distance travel feature.

Form factor (shape)

So, we reviewed 25 basic functions of modern mobile phones. But they did not affect such an important moment as the form of the device. It is also often called the form factor. The form of the phones are divided into:

Classic monoblock . This is a monolithic apparatus, which has no moving parts. Sometimes a similar device is called "brick" or "brick". The monoblock is, for example.

"Folding bed" ("book") . The body of the apparatus folding. Consists of two parts. Reminds folding notebook. Example -.

Slider . The device consists of two parts that shifted relative to each other. Such an apparatus is, for example.

Rotator . The phone contains the mechanism rotating along its axis. As an example, you can lead.

Bracelet . Such a device is worn, like a clock, on the wrist. An example of such a phone -.

There are phones with other form factors (double slider, lateral slider, horizontal clamshell), etc. However, it is the above-mentioned options today received the greatest distribution.

PDA, smartphone or "just phone" - What is the difference?

Modern phones are divided into "simply phones", smartphones and communicators (PDA - pocket portable computers). The fundamental difference between the "simply phones" from the PDA and smartphones is available in the last two full-fledged operating system (Windows Mobile, Symbian OS, Android, etc.). It allows you to install various programs on these devices that expand the functionality of the devices. It can be packages office programs, electronic translators, audio and video players, etc. It should be noted that a clear separation between PDAs and smartphones today does not exist. Sometimes these two term are completely separated. However, there is an opinion according to which the communicators should include devices with a full-fledged operating system and a touch screen. With such a classification, it turns out that the smartphone is a PDA with a conventional, non-sensory screen. There is a device that can be found to communicate to communicators, however, it is positioned by the manufacturer as a completely separate apparatus. This is famous from Apple.

This company traditionally positions its products on the market. Selects them from the total mass of all such devices. At the same time, it gives them the audible names, starting with the English letter "I".

Weight, dimensions and battery capacity

It is impossible not to affect the following characteristics of any mobile phone: Weight, dimensions and battery capacity. Most modern mobiles weigh no more than 100 g. The PDAs and smartphones are usually different (above 100 g). Also, "elevated" weight is characteristic of "image" phones. Cause - In their designs, various additional decoration elements are used. For example, gold or special sapphire glass. The most famous company engaged in the production of expensive "image" phones is vertu.

Mobile phone dimensions are the most different. Of course, smartphones and PDAs will be more ordinary mobile phones. There are special "female" or "ladies" phones. They differ in small sizes that allow them to be comfortably lying in the hand.

An important indicator is the battery capacity. What it is higher - the better. The device will need to charge less frequently. Increased weight of smartphones and PDAs often just caused by large amounts of battery required. However, it is better to pay attention to the not capacity of the battery, but the opened manner of the phone. Moreover, there are two modes of operation: conversation modes and standby mode. It is clear that a rather powerful battery will be set up with a large screen and high resolution. Especially in comparison with a simpler device. But energy consumes the "advanced" device will be greater. So, charging can end faster than a simpler phone. Let the battery last and weaker. So be careful! Pay attention to these parameters: phone operation time in standby mode and talk mode. Of course, you also do not prohibit any battery power to see and evaluate the battery power. It will also be useful, especially if you have already had experience using a similar device. For example, similar to PDA or Musicphone.

Screen

The phone screen may be simple or touch. The touch screen reacts to touching it. In this case, it is an element of control. The phone can be arranged so that the only element of the control will be a touch screen. This is how the well-known iPhone is arranged. However, today there are still phones with auxiliary controls - buttons. However, probably, push-button devices will be ousted by touch.

An important concept is screen resolution. Resolution is the number of pixels on the horizontal and vertical axes. Pixel - the smallest element (point, grain), which is capable of displaying colors. The permission is more - the better. The image will be more detailed, it will not seem "grainy". The screen resolution of the above mentioned iPhone is 480x320. For most Nokia, Samsung phones, etc. it is 240x320.

Screen size also plays an important role. Working with a phone that has a fairly large screen, very nice. On such devices, it is convenient to watch photos and videos. Large screens are characteristic of smartphones and PDAs. In sunny weather, however, the touch screens of the PDA are very glare. They say that they are "blind." Control the device in this case becomes very problematic. Partially the problem solve special protective anti-reflective films. They stick directly to the device screen.

Conclusion

I hope that this article helped you understand the main possibilities of modern mobile phones. I want to believe that now the choice of the device will be done much easier for you. Which of the above functions are really important - to solve only you. The more functions of the device, the more it will cost. For functionality you have to pay. And whether you will use the fact that you will give your money - will show time. Therefore, approach the choice of the phone in detail and reasonably. Observe the principle of a good tailor: "Someone seven times - a rejection once" (and in this case, rather, buy). Before buying, consult with relatives, familiar, seller. Feel free to ask even the most stupid questions in your opinion! It is not ashamed not to know, ashamed - not to ask. Pretty think about your future acquisition.

Successful and delivered shopping for you!

To date, various models of phones there are a huge set and when the question arises as to how to choose a phone, many are simply lost.

Yes, online stores have the ability to choose a gadget by parameters, there are even platforms that take data from several stores and compare characteristics and prices.

But because of this abundance of models, an ordinary person simply cannot understand which mobile phone is better and experiencing real flour selection.

To reduce them, we will consider below, which criteria usually choose phones. After that, everyone will be able to understand what he needs and make the right choice.

Criterion number 1. Budget

No matter how cool, and everything always rests on the amount of funds that we can spend on buying a mobile phone.

Tip №1: Even before buying a new gadget, determine how much money you are willing to spend.After that it will become clear what to count on.

In general, all phones can be divided into such categories:

And if you need a phone for this, you choose from models that cost up to 1000 rubles.

And the only characteristic that should take place when choosing a dialer is the quality of communication.

Here is meant how clearly the voice of the interlocutor is transmitted. And here the phones from Fly are highlighted.

An example of a good dialer is Fly DS105C, which can be bought for 800 rubles. If you characterize it in two words, it will be the words "affordable" and "simple".

Indeed, it will be very difficult to find an easier mobile apparatus.

The battery in it is 900 mAh, which is enough for several days of work without charging (276 hours in standby mode).

Its dimensions are only 110x45x14.6 mm - very easily fit in hand. There is a radio, audio player and even player for video in MP4 and 3GP format.

In general, the perfect choice for those who in your pocket is quite some money and to whom the phone is needed clean for calls.

But on the courtyard still the XXI century and if you really buy a phone, you can dwell and buy something more interesting. Then you need to pay attention to all the criteria below.

Criterion number 2. OS (operating system)

The operating system is in each modern phone.

The most popular of them are:

1. Symbian. This OS today belongs to Nokia and, accordingly, is used only on devices of this company. Now it is far from being so popular as it was 4-7 years ago. And they displacing its following systems in our list.
2. Android. Most modern phones work on android. OS is constantly updated, improved, and it is often buggy and does not work as you want the user.
   At least this is evidenced by the reviews on the Internet, left even in 2016. On the other hand, the system is the most sought-after, it is used by Samsung, HTC, Motorola and all Chinese phones, so they talk about it most.
3. Apple iOS. System designed specifically for Apple phones. There is nothing to discuss here - buy Apple phone, get iOS.
4. BlackBerry OS. Like iOS, developed only for BlackBerry phones. This system is a record holder on this list, as it was created back in 1999.
5. Windows Phone. Developers tried to make an analogue of Windows 10 for computers with the same multi-colored pictograms of various labels in the form of squares, only for smartphones. Very popular in the West.

Yes, there are still many different operating systems, for example, OS Bada, Palm OS, Open Webos, Maemo and others. But choose better of these five.

And the reason for this is that they are simply supported in our area, that is, if the phone on the same android breaks, it will be repaired with it, but with the phone on OS Bada will deal with a lot more difficult.

It will take to look for a master who would deal with in this matter, and this is very difficult.

So, operating systems are defined. Now it remains to understand which OS you want on your cell phone.

Select the operating system follows such criteria:

1. Purpose of a smartphone. If it needs a business person who constantly works with documents and wants to configure the interface for himself, then it is suitable Windows Phone, and if for games and all sorts of "lotions", then definitely Android.
   If in priority reliability, then there is a person to care about the games, but he wants to get a phone with whom nothing happens (for example, do not bother viruses), then this is BlackBerry OS.
2. Budget. If there are not so much money in your pocket, but I want to get a good gadget, then choose Symbian. This OS and is focused on the budget class. But if the money is not a problem, then you can spend on Apple with Apple iOS.
   Android phones are a kind of golden middle.

Tip # 2: Best look to the sideAndroidAfter all, today most applications are written for this OS. In addition, phones withAndroid cost cheaper thaniPhone.But have almost the same functionality. And, in the end, this is the most popular OS in our area.

Criterion number 3. Phone power

The way how powerful the phone can be determined by the characteristics of the processor and the RAM of the phone.

CPU

This feature is associated with a power of a mobile phone. The power of the processor is determined by its frequency. It is measured in Hertz (Hz) it is logical that what they are more, the better.

To date, normal for phones is the figure of 1-2 GHz (Gigarez).

In addition, the processor power depends on the number of cores, each of which has its own number of Hz.

Interestingly, even on the most powerful modern smartphones, the number of GHz rarely exceeds 2.5 GHz.

Is it allocated to the Chinese masters who manage to accommodate into a regular phone up to 3.5 GHz. An example of such a phone is ZTE Nubia Z9.

Considering the most expensive models and phones from the category of budget can be seen one interesting feature.

It lies in the fact that the power of the processor on budget smartphones Often more than on the most expensive.

This is quite logical, because manufacturers simply do not know how to make the processor more powerful.

Therefore, if it is important for you that the phone is powerful, you can not overpay.

An example of a truly powerful apparatus is Xiaomi Redmi Note 3 by 2 GHz in the processor. It is about 230 dollars.

For comparison: Samsung Galaxy S7 costs about 830 dollars and in it 2.3 GHz. In Xiaomi to all other 32 GB of internal memory, GPS, GLONASS and many other useful features.

The disadvantages of the phone are only in a bad chamber, a dull display (we will talk about this) and a non-removable battery - if it breaks, it is not replaced by it, and this is additional inconvenience.

But Xiaomi Redmi Note 3 is one of the most powerful phones today due to the following characteristics - RAM.

RAM

Another characteristic that affects the power.

Measured in gigabytes (GB). The number of GB and determines how quickly the system can respond to user actions and process various operations.

So, in Xiaomi Redmi Note 3 of these gigabytes of the whole 3. In the same Samsung Galaxy S7 there are already 4 of them, but it is an order of magnitude more expensive, as mentioned above.

Select the phone, depending on the RAM, there is no point, because with a powerful processor no one will never put little operational memory into the phone, otherwise the device will not be able to work correctly.

The bigger, the better.

In this program, each phone gives an assessment depending on its performance.

So, in early March 2016, a study was conducted, which showed that the most powerful phones have a processor called Qualcomm Snapdragon 820.

In second place - Apple A9 (only for the iPhone), and took the third line Samsung Exynos. 8890.

1. Huawei Kirin 950;
2. Samsung exynos 7420;
3. Qualcomm Snapdragon 810;
4. Qualcomm Snapdragon 652;
5. Apple A8.

Based on this, you can form the following advice.

Tip №3: So that the phone is powerful, one of the processors listed above should stand on it.

But the problem is that such processors are not put on budget smartphones.

Therefore, here is a hint for those who look in the side of the state employees: also well shown by Qualcomm Snapdragon 615, MediaTek MT6795 (he also Helio X10) and Qualcomm Snapdragon 801.

An example of a phone with the most powerful to date, the Qualcomm Snapdragon 820 processor is oneplus 3 with 4 GB RAM.

The cost of such a pleasure is 500-600 dollars (so far the model has not yet been published).

Tip №4: When choosing a phone, look at how much he dials in the programAntutu. Benchmark. (This information can be easily found on the Internet). This will make it possible to actually see how powerful one or another model.

Criterion №4. Working hours

How much time the device can work directly depends on the battery. The battery capacity is measured by milliamperes. Of course, than them more, the better.

Approximately in phones with 2 GB RAM and the processor frequency of 2 GHz should be at least 3000 mAh.

This will give the device the opportunity to work about two days with a small number of games, a large number of use of the Internet and working with documents.

If you continuously play some heavy games, For example, GTA or NOVA 3, then the device with 3000 mAh is enough for about 6 hours.

But even on the most powerful phones Rarely when there are more than 4000 mAh. Yes, there are some "unusual" models with 5000 mAh, but they work for a short time.

This is very clearly visible on the example of the BRAVIS POWER phone. The phone is 4500 mAh, but there is practically no capacity and, judging by the Internet reviews, the phone has about 4-5 months.

It costs 115 dollars. The combination of such a price and such battery capacity causes many questions. And not in vain.

From the above, you can conclude the following: if the phone costs less than 150 dollars, and the battery capacity on it is more than 3000 mAh.

It is very strange and such a device is unlikely to work for more than a year.

On the other hand, often manufacturers try to save on this parameter and try to take the processor, RAM and other parameters.

Yes, a capacity of about 2,000 mAh is allowed on budget phones. After all, there all other elements do not consume so much energy.

Therefore, you can withdraw a certain gold parameter.

Tip №5: The battery capacity must be from 2000 mAh up to 4000 mAh.

Criterion number 5. Built-in memory

This parameter determines how much data is placed on the phone.

Usually, on budget phones, manufacturers try to put no more than 16 GB, in more expensive phones there may be 32 GB, and 64 GB.

But, depending on this parameter, you need to consider only one condition - is it possible to use the memory card.

If you can insert an additional card, then the small amount of the built-in memory is not trouble.

But it happens that there is no such possibility, and then it is the built-in memory that will play a major role.

True, there is still the ability to use cloud storage, but then you will be tied to the Internet - if it is not, then you will not see your files.

Therefore, it is ideal that the phone was about 8 GB of internal memory and the ability to insert a memory card.

About the memory card worth saying something else. Often manufacturers make the phone in such a way that he can take SD cards to 200 GB - 1 TB.

The fact is that if there are too many files in the phone, about 100 GB, it will slow down and something will have to be deleted.

After all, even himself powerful processor and a large number of RAM not enough for the processing of such a number of information.

Accordingly, there is simply no meaning in too roomy memory cards.

Tip number 6: Choose phones with the ability to insert a memory card up to 100 GB.

Criterion number 6. Camera

Check how high-quality and clear it turns out a photo on a particular phone is very simple.

To do this, you need to take a picture of something and maximize some part of the picture, that is, apply the zoom function.

If the enlarged part of the picture breaks down, it turns out to be fuzzy, then this means that the camera on the phone is not very high quality.

But sometimes it is not possible to take the phone in the hands and "try it to taste."

Then you need to look into two characteristics - the number of megapixels and the diaphragm.

Today, almost all manufacturers of phones and cameras try to attract people with the number of magpixels.

This value reflects how many pixels form an image. But not one of this feature affects the quality of the picture.

Still affects the size of the diaphragm or relative hole. You can explain the value of this value on the example.

Imagine that you are in the country, it is raining and you need to assemble as much water as possible.

If you put a conventional mug with a diameter of 15 cm, then it will not get a lot of drops, and the water will be gathered slowly.

But if you put a large bowl with a diameter of 50 cm, it will get more drops and the container will be filled much faster.

In the same way, the diaphragm reflects how much light falls into the camera lens.

The diaphragm size is indicated as "f / size". In the picture you can see the dimensions of different diaphragms.

It becomes clear that than this number is less, the more the diaphragms are more, respectively, the more light it can catch and the better the pictures are better.

Megapixels + diaphragm

It is interesting that now on the Internet they write a lot about the fact that nothing depends on the number of megapixels and only the diaphragm affects the quality of the pictures.

In fact, this is not quite true, because there were cases when the developers, using this myth, put little megapixels on phones, and the diaphragm did large, as a result, the pictures were not very high quality.

Therefore, it is better to choose phones with a minimum value "F /" and with a maximum number of megapixels.

On the other hand, it is very rare to meet a phone with a large number of magpixels and a large value "F /", manufacturers combine these parameters.

According to these parameters, SAMSUNG cameras show themselves very well. In general, this company has many of their technologies, one of them concerns exactly cameras.

The favorite in this respect looks like SAMSUNG GALAXY S6 with the main chamber of 16 megapixel and frontal 5 megapixel.

To clearly display it, here is a night landscape shot, made on the iPhone 6.

But a snapshot of the same terrain made to Samsung Galaxy S6.

Agree that the photo made on the Samsung Galaxy S6 is brighter, saturated. In the end, it is more permission that allows you to see the smallest details in the picture.

Tip number 7: When choosing a camera on the phone, focus on a combination of megapixels and aperture.

It is not worth paying attention to only one of these parameters, because often manufacturers, trying to deceive their customers, write only the number of megapixels or only aperture (more often first).

Criterion number 7. Screen

Everyone wants to make the picture on the phone, too, was bright and rich. But what to watch to choose such a phone? Brightness and saturation depend on four parameters:

• Diagonal.
• Resolution.
• Pixel density.

Consider each of them in more detail.

Diagonal

This characteristic reflects how much the distance from one corner of the screen to the opposite one. The figure below shows this distance.

Screen diagonal should be chosen depending on why a phone is needed:

• for calls and basic functions - 3-4 inches;
• for Internet surfing and reading books - 4-5 inches;
• for games and watching movies - 5-6 inches.

Everything is very simple here.

Resolution

Screen resolution is directly connected with a diagonal in such a relation:

• for a diagonal of 3-4 inches permission can be 480x800;
• for a diagonal of 4-5 inches permission can be 960x540;
• for all the rest, permission can be 1280x720 (HD), 1920x1080 (FullHD) and 2560x1440 (QuadHD).

Of course, the more permission, the clearer it will be a picture.

Pixel density

Writing as PPI (PIXELS PER INCH) and expresses how many pixels are placed in one inch of the screen. It is clear that than this characteristic is higher, the clearer should be an image.

Usually manufacturers try to make the number of pixels on an inch corresponding screen resolution.

So, on screens with a resolution of 1280x720 can be up to 300 ppi. In principle, choosing a phone depending on this characteristic no meaning.

You need to look at the previous two parameters - diagonal and permission. In addition, the following parameter is very important.

Screen type

To date, the most popular types of screens are the following:

• OLED;
• AMOLED and SUPER AMOLED;
• AFFS.

In our area, you are unlikely to meet the phones with the screens of the last two types, but in the West they are very popular.

It is very interesting that from the first three types best of themselves show models with Super AMOLED screens.

The phone with HD resolution and the SUPER AMOLED screen will look much better than the model with the fullHD resolution and the IPS screen.

In particular, the viewing angles will be much better.

This parameter means that the phone can be viewed almost at a right angle and at the same time be able to see what happens on the screen.

In the figure you can clearly see the comparison of these two types.

Especially it concerns samsung phoneswhere many of your unique technologies are applied, so Samsung with Super AMOLED is much better than any other phone with Super AMOLED.

However, other screens look quite well, and attention should be paid to this characteristic only if you are really important saturation and clarity of the screen.

Tip №8: If you are important saturation and brightness, choose the phone withSuper Amoled. screen.

Here is another photo that confirms that it is best to choose exactly super amoled screens.

The most extreme left phone here Sony Xperia Z Ultra with the TRILUMINOS screen, the second - Samsung Galaxy Note 3 with Super AMOLED, then comes Sony Xperia Z1 with the same Triluminos and the last - LG G2 with IPS.

It is clearly seen that samsung looks better than the rest.

Criterion number 8. Brand phone

As for the brand of the phone to choose, the following provisions will help:

• If it is important for you that the phone can be fixed in our area, then it is Samsung, Lenovo, Fly, Prestigio, Asus, Philips, Sony, LG. The fact is that in the CIS countries there are certified centers that carry out repairs.
  The remaining phones will need to be sent to repair, most likely to China, and this means that it will have to pay about 150 dollars for shipment. It turns out that there is no sense from the guarantee.
  You can, of course, find a local master, but then no one answers the quality.
• If productivity is important, then Xiaomi, Meizu, ZTE, Sony and the vast majority of other Chinese brands. In principle, SAMSUNG shows well, but it costs more.
• If a good camera is important, then Samsung, Sony, Apple, LG, HTC, Lumia and some Lenovo models.
• If it is important for usability, then all OS phones operating system Android.
• If it is important, the time of work, DEXP, Fly, Philips, Highscreen, Lenovo and Samsung.
• If reliability is important (so that the phone does not break), then Sony, Samsung, LG. Everything else most often fails after a year of use. Yes, if among the same Samsunov exception, but mostly all models work at least 5 years.
• If you don't want to spend a lot ("I want inexpensive, but good"), then Xiaomi, Meizu and other Chinese brands.
• If you want to show that you have a lot of money, iPhone. The fact is that some special characteristics do not possess these phones, and they are expensive due to advertising. Therefore, buy an iPhone only in cases where you just want to spend money.

In general, choosing a brand, you need to focus on what is important to each specific consumer.

Criterion number 9. Protective characteristics

I really want the phone to do not crash, endured in the water and other emergency situations.

Of course, you can cover phone covers, protective films and generally wrap in the film and wear in a velvet container, but I want the phone to and can withstand at least fall on the ground.

Find a smartphone with a high degree of security is very simple - usually written "IP ...", for example, "IP67". This means the level of protection.

By the way, the most secure phones and have the degree of protection IP67. Therefore, if you plan to often drop your gadget, it must be "IP67".

An example of such a device is the Samsung Galaxy Xcover S5690, which is withstanding entering water, finding in the ground and can even withstand if the car moves!

Tip №9: If your phone's strength is important, select devices with IP67 protection level.

But without this level of protection, the mobile phone may well be reliable if it has a special protective glass Gorilla Glass.

This glass has a high degree of resistance to scratches and shocks.

With such glass, no additional protection will be needed.

Of course, if the phone moves the machine, the screen will still crack, but it will endure the fall on the pavement road calmly.

But even if on the phone it originally does not have such a protective glass, you can always buy an extra glass.

But here it is important not to be mistaken and not to buy the usual film, you need to choose exactly the glass!

Tip №10: Choose the phone C. protective glass Gorilla Glass or together with the phone immediately buy additional glass.

In addition, choosing a reliable phone. It is important to look at the material of the housing.

Best of all, of course, buy devices with a metal case. But the good plastic in a high-quality protective case will also endure the blow to the Earth.

RESULTS

If you want to hear the opinion of a specialist as to which phones you can buy this year, then experts agree that the most interesting models in all characteristics will be the following:

• SAMSUNG S7. - 4 GB of RAM, 2.3 GHz processor frequency, 32 or 64 GB of integrated memory, camera for 12 meters and 3000/3600 mAh and, most importantly, curved display.
  In principle, the popularity of the phone and will be due to an unusual display. But all other characteristics are pleased. There is such a pleasure about 900 dollars.

• Xiaomi Redmi Note 3 and SAMSUNG GALAXY J7.. Undoubted leaders of phones in the budget category (up to 300 dollars). Both diagonal is 5.5 inches and 16 GB of integrated memory. Samsung has a camera on 13 megapixel, but she takes better than Xiaomi.
  RAM at Xiaomi 2 GB, Samsung - 1.5 GB. In Antutu, the first is typing about 50,000 marks, and the second - 41000. Samsung wins due to best Display. If you are important than performance, choose Xiaomi.

• Sony Xperia Z5. 5.1-5.9 inches screen (depending on the modification), 28 MP Main chamber, 4200 mAh and durability to dives in water - all in the best traditions of Sony. The cost of about 800 dollars.

How to choose a phone - the main selection criteria

Articles and Lifehaki.

Over the past few decades, the mobile phone has passed the way from the subject of luxury to the subject matter of the essential, and today it has become accessible even to schoolchildren. But I must say that many people do not even imagine what is the mobile phone, not to mention, and it is, in principle, and nothing to know. Although there are also those who seek to learn from what is such an important thing today. Just on such people and the information of this article will be calculated.

The main details of which the mobile phone consists

1. Electronic board. This item is the heart of the mobile device and ensures its basic functions.

2. The details of the housing to which, first of all, the keyboard includes, as well as body components depending on the device model (slider, monoblock, flip, and so on).

3. Display. Displays are classified into two groups:
- Displays connected to the electronic board;
- Displays soldered to the housing.

4. Battery that provides offline mode Mobile phone operation (it may be nickel-metal hydride, lithium-ion or lithium-polymer).

5. In addition, answering the question about what a mobile phone consists of, you must not forget to tell about the chamber that allows you to make a photo or video.

Second components of mobile phones

The group of secondary components of mobile phones includes the details described below.

1. Dynamics and microphones. These are quite important components (although they refer to the secondary class), as they are responsible for the sound quality and its playback. In modern models of phones, about three microphones can occur, the first - for conversations, the second - to record the sound to the voice recorder, and the third is to suppress noise when telephone conversation.

2. Clay. This is a detail that is capable of connecting several movable parts in the phone, in addition. Special attention is paid to the plumes.

3. The vibromotor, which is responsible for all the well-known vibration on the phone.

4. Antenna (antenna module), which is intended for listening to radio stations. Antenna, as a rule, is located inside the housing and is a pin or plate of a specific form.

Summing up, you must say that this idea of \u200b\u200ball components of a mobile phone can be called conditional, as some of the listed elements may not enter the basic configuration of mobile phones, because their equipment may vary depending on their price category.
