How many cell phones are there in the world? How to choose the right smartphone based on parameters - expert advice

Hello Dear friends, today we’ll talk about how to choose a smartphone in 2018 and what characteristics you should pay attention to. If you look at the mobile phone market in 2017, approximately 97% of it consists of smartphones and their number is growing every year. If you do not want to read the information in full, you can watch the thematic video below in the article. For those who want to understand in detail the choice of the best smartphone, below we will talk about it in great detail.

For what purpose?

This is probably where you should start; some are inclined to believe that you can buy a regular push-button telephone and enjoy life. Yes, of course, for some residents of our country such a phone will be enough. The phone allows you to make calls and listen to music. The entire minimum of functions is presented in full, but good smartphone In addition, it performs more complex tasks. It can become a real assistant in a variety of matters: how to choose a place to relax for the evening, find out reviews of a particular establishment, find the way to an unfamiliar place using a navigator, while away the time playing logical or entertaining games, take high-quality photos in any weather and much more.

Many people simply choose a smartphone based on price-quality ratio and don’t bother with the rest. Of course, this is a correct and competent approach; you don’t need to overpay for additional options if you won’t use them anyway. There are many categories of citizens, and each has its own specific type of smartphone. For some, the best smartphone is the one that allows you to run all existing toys; for others, it’s just a work assistant that allows you to exchange information with other people by mail or edit office files, or simply increase self-esteem or maintain your lifestyle .

Therefore, when purchasing, you definitely need to pay attention to this so as not to overpay for something that you don’t need at all!

Well, we’ve already sorted out the simplest part, now there will be a maximum of technical nuances, because every year smartphones become similar in characteristics to laptops and an 8-core processor in a phone won’t surprise anyone, as well as a 6-inch display, but we’ll talk about that more details

From the very beginning, a very difficult question arises: which diagonal to choose? In 2018, fashion dictates the rules and now you can find a smartphone with 4 inch screen it is very difficult to meet, although this is the figure with which it started Apple company. Well, today the average display size is about 5-5.5 inches, which is enough for all modern needs. Only those people who use the phone one hundred percent can experience all the delights of a huge 5.7-6 inch screen.

Don’t forget about ergonomics, because a smartphone should not only be multifunctional, it should also fit comfortably in your hand!

A very important indicator - screen resolution. It can be very diverse. Of course, it is best to buy a model that has a high-definition display, that is, Full HD 1920*1080 pixels, or at least HD 1280*720, if you want to buy a smartphone larger than 5 inches, although of course there is already 4K resolution, it’s simply unrealistic for an ordinary person to see the difference from Full HD!
Also, do not forget about the type of display (matrix). The quality of the picture, the presence of glare, contrast and viewing angle directly depend on this. A high-quality display allows you to view everything that is presented on the screen from any angle and always with a beautiful and rich color scheme. IN this moment 3 types of matrix are used:

1. Super Amoled is the most common matrix of Samsung smartphones, which is famous for its black color and brightness.
2. IPS is the most popular matrix in the world, with over 70% installed.
3. Retina is installed only on Apple phones, and Samsung developed this technology together with LG and today it is the best matrix in the world.

Currently, smartphones are supplied to the market that can have three types of operating systems, namely: IOS, Windows, Android. There are, of course, others, but they are less widespread and therefore we will not dwell on them.
Android

Currently, more and more manufacturers are abandoning their own operating systems, giving preference to this one. This is due to the fact that a huge amount has been written for Android free applications, plus it is easy to use, and also allows you to optimize the interface for yourself and your smartphone will be unique.

iOS is operating system, which was created specifically for Apple smartphones, it is unique in its simplicity and optimization for all applications. Compared to its competitors, with lower specifications, this OS works better and faster, plus there are no viruses for it.

Of course, this OS ranks third in the world in terms of the number of users, since it appeared later than all others and the smartphones themselves with this OS are much smaller than those with the same Android. And all because it still needs to be polished and many different applications need to be made, but the potential is very great.

Since two processors with a clock frequency of 2 GHz seem to be the same, in reality one will be faster than the other, since the clock speed indicator is not always the key to success, my advice is to build on such indicators if you plan to use your smartphone to its full potential. Therefore, it is better to compare processors special program Antutu benchmark, or look at performance graphs.

The next important factor is the number of cores, here in principle everything is simple, the more the better, but there are some nuances:

A processor with 4, 8 and 10 cores consumes a large amount of energy and therefore discharges quickly, although many manufacturers make a smart move and change clock frequency to a lesser extent, and also disable some kernels in those moments when this is permissible. And of course, they are turned on at full power as soon as a powerful application is launched.

Thus, they killed two birds with one stone, but my personal advice is that if you are not a gamer, then an 8-core mid-range processor will be enough for you! And if you need just such smartphones, then follow the link Here are the 10 best smartphones in terms of price-quality ratio.

The best processors in 2018

1. Samsung (Exynos 9810, 8895 and 7885)
2. Qualcomm Snapdragon (435, 625, 630, 660, 835, 845)
3. MTK (Helio x20, x30, P25, P30)

Video accelerator

Video accelerator or GPU is an auxiliary microprocessor for games that only handles graphics processing.

Memory

Memory is very important parameter, but it’s quite easy to figure it out, you just need to know that there are two memories:

• For data storage (smartphone main memory)
• To accommodate command data for the processor to perform the necessary tasks (RAM or random access memory).

RAM

The more random access memory, the faster and more you can run simultaneously applications and games. The maximum amount of RAM today is 8 GB, but for normal operation For a smartphone, 3-4 GB is enough for every day, but you shouldn’t consider less, since the operating system itself takes up memory and you will have very little left to use and you will have to constantly close applications in order to open the next ones.

Main memory

Some expensive smartphones have only one memory, which is offered by the manufacturer itself from 16 to 256 GB, and it is impossible to change its indicator. But there are also powerful smartphones with an additional connector for flash drives (popularly called MicroSD flash drives) and with its help you can increase the memory up to 2 TB, you just need to ensure that there are no slowdowns in games or recording videos with high resolution. But there is a nuance here:

In most cases, downloaded programs are installed only on the main memory of the smartphone and it is not always possible to transfer them to a flash drive. For example, the well-known Navitel navigator with maps of Russia takes up about 1.5 GB, and in many budget smartphones the main memory is only 8 GB, plus the OS itself takes up about 2-3 GB, and you still have about 5 GB for downloading games and applications, which is extremely small!

Camera

The camera has become one of the most important parameters in choosing a smartphone not so long ago, but has already taken a leading position. And all because people increasingly began to use the camera with or without reason, as the quality of the pictures became better and better every year.

A pixel is a small dot that makes up an image, and for example, 6 Megapixels is 6,000,000 pixels, and the resolution is 3000x2000, which is enough for a high-quality photo, since a printed 10*15 photo has a preferred resolution of 1712x1200 (2 MP), draw your own conclusions.

Therefore, it is advisable to take a selfie camera from 8 MP. It will allow you to do not only good photos, but also shoot videos for streams. Some modern models have highest quality photos of 20 or more megapixels, and the record so far is 41 megapixels from the Nokia 1020. Of course, such a camera is very cool, but in order to make a camera super cool, megapixels alone are not enough; optical stabilization, automatic focus, camera sensor, ISO come to the rescue - light sensitivity and the best camera of 2018 is only 12 megapixels from the Samsung S9.

• Autofocus - makes your photos clear by helping the camera focus and select the right settings for a particular shot.
• ISO is an equally important parameter; the larger its operating range, the better the pictures will be in different conditions, be it twilight or very bright lighting, the pictures will always be super!
• Optical stabilization helps make the picture clearer when moving, improving significantly especially video recording.
• The quality of the optics and its size are purely individual and can rarely be boasted, but there are exceptions, as we already said Nokia 1020, this smartphone is included in our rating best cameras ofofons.
• Well, the last thing is a flash, you can’t live without it, in almost all smartphones it is LED, of course there is dual and xenon.

Well, with video recording everything is simple, it is desirable that the recording be in FullHD resolution and have optical stabilization, so that the picture does not shake, and again, the presence of a flash, so if your phone has all the above parameters, then the recording you saw will be excellent.

Battery

The battery has a very important role in the process of its life. In fact, everything is quite simple - what more powerful device, the more energy it consumes. Battery capacity is measured in Amperes. This parameter should be the maximum possible, especially if we are talking about a gaming smartphone. The maximum battery size for today is 10000 mAh. Here, in principle, everything is simple, the more the better, my advice to you when choosing a price-quality smartphone is to try to buy one with a battery of 3000 mAh, but even here there is a catch:

Many manufacturers write beautiful numbers on the packaging, but you should not always trust this information, especially if you choose chinese smartphone!

Appearance

Not the least role is played by appearance gadget. Of course, it can always be changed with the help of various accessories: covers and films with stickers. The phone itself must fit the person perfectly in order to fully highlight his style and, of course, fit comfortably in his hand. Here, as they say, there are no comrades for taste and color! Therefore, many manufacturers make a wide range of colors.

Which company is better to choose a smartphone?

According to statistics, the telephone market is growing exponentially. This forces marketers from around the world and representatives of large companies to regularly monitor sales indicators. Phone statistics allow you to see supply and demand, highlight the most popular gadget models, and evaluate the dynamics of sales growth in the regions.

For example, the US and UK are leaders in smartphone use. In terms of popularity, the iPhone tops the ratings of America and European countries. In 2017, the growth of smartphone users reached 4.77 billion people. China accounts for 1.4 billion people. Statistics cell phones has 1 billion users in India.

Leaders of sells

Samsung and Apple are the leading smartphone suppliers, accounting for about 18% of the total. New phones are coming out with enviable frequency, which cannot but please sellers.

Phone usage statistics:

• 94% of adults (over 17 years old) have a mobile device;
• 56% of them are smartphone owners;
• 29% of users say they cannot live without a phone;
• 9% have used a mobile device at least once to participate in charity.

The cell phone is recognized as the fastest-adopted innovation in the world. Mobile devices are seen as the main key to socialization.

In 2017, 74% of users made purchases through Phone purchase statistics also show high figures. 56% mobile devices were purchased through cell phones. What criteria do buyers use to evaluate mobile devices?

• by manufacturer;
• by productivity;
• by quality;
• by sales.

Statistics best phones updated quarterly so that the user has the opportunity to choose new products and high-quality products in the industry mobile communications. As phone statistics show, at the end of 2016 the flagships were:

1. ASUS ZenFone 3 Zoom ZE553KL 64Gb – a mobile device with the most powerful battery. The average in Russia is 28,000 rubles.
2. HTC U11 64Gb – presents itself as the best smartphone in the world in terms of power and performance. The device has one of the best cameras among the presented flagships. In Russia, such a smartphone costs from 45,000 rubles.
3. LG G6 64GB is a new product that has a number of additional functions, has a stylish design. However, it creates a feeling of copying another sales leader - Samsung Galaxy S8. The starting price is 42,300 rubles.

Global phone statistics show that this is not the entire list. But in addition to flagships, smartphone manufacturers produce budget options of its products. Statistics of purchased phones:

1. Samsung Galaxy J1 Mini.
2. LG K7 X210DS.
3. Xiaomi Redmi 4.
4. Samsung Galaxy J1 (2016).
5. LG K5 X220DS.
6. Lenovo Vibe K5.
7. Samsung Galaxy J3 2016.
8. ASUS ZenFone Go ‏ZB452KG.
9. Meizu M5.
10. Meizu U10.

Mobile phone usage statistics in 2013 :

Phone statistics show that Apple and HTC are the most resilient. The components of mobile devices allow us to believe that smartphones will last for many years. However, you need to use gadgets carefully.

Additional bonuses

It is also impossible not to take into account the statistics of the phone accessories market. There are a huge number of them, for every taste and color. This includes cases (of all shapes and sizes) with their bright pictures or a strict design, various laces, holders (for amateurs), Bluetooth headsets (optimal for drivers and businessmen). And this is not all that designers could come up with to maintain the level of sales of mobile devices.

Smartphones for everyone

Telephones in Russia are very popular. The market is flooded with gadgets with different properties. There are phones for children (with built-in function parental controls) and phones for the elderly Chinese manufacturers produce cool phones made to look like toys or cars.

However, the real BOOM in the world of new products occurred relatively recently, when they were released waterproof phones. Covering with expensive material affected mainly flagships, but the demand did not decrease.

Telephones in Ukraine are no less in demand than in Russia. Stores offer telephone catalogs for any age, financial ability and consumer demand. The cost of mobile devices ranges from $100 and above. Latest phones have such a strong signal level that they can easily maintain communication in deep subway tunnels.

applications for increasing sales through mobile devices. The user can only buy the smartphone he likes and improve the quality of his own.

If you don't constantly monitor the smartphone market, then it can be difficult for you to choose the right phone that you won't regret buying later. The site’s experts have collected for you answers to the most important questions about choosing a smartphone. Here you will learn how to choose the phone that is right for you, which phone is best to buy in 2018-2019, and how to save on your purchase.

What do you expect from a new smartphone?

Before buying a smartphone, you should decide on the set of features that you expect to receive. Do you need a powerful device or just a dialer? Do you want high-quality photos? Do you expect your smartphone to work for several days without recharging? Do you need metal case and features like a fingerprint scanner, water resistance or frameless?

Today you can find a smartphone to suit every taste, but it is better to avoid some misconceptions. For example, if a phone has twice as many processor cores and RAM, the screen resolution and the number of megapixels of the camera have increased, then it will definitely be better. This is not entirely true. , obtained by our experts after testing devices in the laboratory and during daily use, clearly showed that many parameters and characteristics do not directly affect the quality of the phone. Therefore, if you have a smartphone from last year or the year before, then it is absolutely not necessary to change it precisely because of its “outdated” characteristics.

If you still decide to change your phone, pay attention to the constantly updated website compiled by experts. With it you can compare smartphones by various parameters or just find out which smartphone is the best today. This became possible due to the fact that for the first time all phones were tested using a single method. Also, every year we take stock by making selections, as we did in 2016, or by choosing best smartphones years, as, for example, they did it in and years ..

Which operating system should I choose?

The smartphone can run on the operating system iOS, Android and some others, for example, Windows. But these two operating systems are the most popular.

iOS- Apple's operating system that runs everything portable devices companies: iPhone, iPad and iPod Touch. The main advantages of the system are ease of learning and a high level of optimization, and at the same time stability, high speed and excellent compatibility with applications. Another plus is the constant system updates for most of the company’s devices, but keep in mind that older gadgets may slow down after updating. The main drawback of iOS is that the system is closed; for example, you can’t just download a movie from your computer or put a song on a call. iOS is also characterized by limited support for multimedia formats, and it is also impossible to replace many basic applications and change the appearance of the system without doing a Jailbreak - the operation of opening access to file system to expand the capabilities of the device. Just keep in mind that after Jailbreak you will lose the warranty on your gadget. Over the past couple of years, Apple has been working on fixing the shortcomings. For example, they are expanding the options for setting up the phone - adding support for third-party keyboards, the ability to transfer some media files to the iPhone without iTunes Help and already allow you to delete some pre-installed applications. Also keep in mind that iOS devices are, on average, significantly more expensive than their Android competitors.

Android- operating system from Google with wide customization options. Standard browser, writing utilities text messages and calls, calendar, notes, keyboard, mail client- Most of these applications can be removed and others that are convenient for you can be installed. You can even change the appearance of the interface. This system has many settings and changeable parameters, and the number of applications and games for Android is huge. Disadvantages: the degree of protection against malware is not as high as in iOS, and the simultaneous coexistence of a huge number of models on different versions systems. This can lead to difficulties with optimization and compatibility with different applications and devices. Another drawback is the limited time support for the gadget. So, most devices receive system updates within a year or two, no more. Then you have to either buy a new device or stay on the old OS.

Windows Phone- operating system from Microsoft, which has almost disappeared from the mobile device market. Its features are the “tiled” style and high speed of operation even on frankly weak hardware. The disadvantages of the system are an unintuitive menu and a small number of applications and games in the store. Now this system is living out its last days on smartphones; you are unlikely to find a Windows phone in stores, except perhaps a budget one.

Which display diagonal is right for you?

One of the main parameters of a smartphone is the diagonal and screen resolution. The dimensions and such an important point as the ease of use of a smartphone directly depend on this.

Examples of smartphones with different display diagonals.

Less than 4.6 inches — compact smartphone with a small screen that is comfortable to hold in your hand, carried in any pocket (this is an important point in the summer, when we walk around in light clothes) and on which it is comfortable to talk even for a long time due to its small dimensions. The downside is that operating a smartphone with such a screen may be inconvenient at first. If you have big fingers or are choosing a smartphone for the older generation, it is better not to consider this option. Due to the increase in device diagonals, finding a phone of this size with good characteristics not easy. These are mainly budget or old phone models, for example. Exceptions include 4-inch or 4.6-inch.

4.6 - 5.3 inches— universal screen sizes. These can be either budget or mid-segment models, or flagship smartphones (for example,). If the diagonal is closer to 4.6 inches, the device fits comfortably in the palm of your hand and is easy to operate with one hand. A smartphone with a diagonal closer to 5.3 inches is not very comfortable to hold in your hand, but on a larger screen it is easier to work with small icons, play games, watch movies, read email, and so on. In this category, you will find both small phones (like the 4.7-inch) and larger models (like the 5-inch or 5.2-inch).

Over 5.3 inches— a separate term was invented for such phones: phablet (phablet, combination PHone + tABLET). Such devices combine the capabilities of a smartphone and a tablet, so they need to be controlled using two hands: with one you hold the smartphone, with the other you touch the screen. Phablets are difficult to carry in clothing pockets; most often they simply do not fit there. A device of this type is suitable for those who are willing to put up with the huge dimensions and corresponding inconveniences of a smartphone. But it seems that today this no longer bothers anyone, and people are ready to endure it for the sake of big screen. Typical representatives of phablets are (5.5 inches) and (5.5 inches). There are also larger models, for example (6.44 inches).

What type of screen do you need?

Manufacturers of modern smartphones, as a rule, indicate information about the type of screen directly on the box. This can also be found in open sources (for example, on the manufacturer’s official website).

TFT/TN— screens based on this matrix are usually used in the most inexpensive smartphones. Key Features- low contrast, narrow color gamut, faded image and small viewing angles. Of course, when purchasing a budget smartphone, you should expect good quality there is no need for pictures. Owners of such a screen are extremely budget smartphones, for example, and .

IPS/S-IPS/PLS— screens based on such matrices have a natural color gamut, wide viewing angles and high level brightness Also this type The matrix has good readability in the sun - this is important if you often use your smartphone outdoors.

Some manufacturers use specific names to refer to this type. For example, HTC indicates “Super LCD” screens in its smartphones, while in reality it is the same IPS matrix. IPS matrices can be found both in inexpensive phones, like, and in flagship models, for example, or.

AMOLED/Super AMOLED— previously, screens based on these matrices were used only in flagship smartphones Samsung, but now they can be found from other manufacturers, for example, in phones or. In addition, AMOLED matrices have spread to inexpensive models, such as. Distinctive features: very juicy and contrasting colors, good viewing angles, wide color gamut, perfect blacks and energy saving. Flaws - high price and “burning out” of blue pixels over time, which is why the service life of such a display is shorter than that of screens based on IPS/S-IPS/PLS matrices. Also, some Super AMOLED screens use Pentile technology, which consumes less power, but the image on it appears grainy and unnatural when viewed closely (with a red halo around letters, icons and other elements).

Screen resolution- another parameter that sometimes leads to confusion. It would seem that everything is simple - the higher it is, the better the image will be. But in reality, you are unlikely to see the difference in picture clarity between a 5-inch Full HD screen (1920x1080 pixels) and a 5.5-inch 4K display (3840x2160 pixels).

In our opinion, HD resolution (1280×720) is optimal for smartphones with a diagonal of up to 5 inches, and Full HD for phones with a screen larger than 5 inches. Extremely clear Quad HD, firstly, will only be useful for tablets or phones with glasses virtual reality, and secondly, this often has a bad effect on the autonomy and performance of the smartphone.

How to choose a smartphone camera?

It is believed that the more megapixels there are, the better the pictures - and this is true, but only partly. The quality of a photo depends not so much on the number of megapixels, but on the size and quality of the matrix, optics, image processing algorithms and a number of additional options. Therefore, first of all, we advise you to look at the quality of photos taken on your phone (you can test the camera yourself in a store or look at the pictures in reviews of the device). In our opinion, some of the best smartphones in terms of shooting quality are LG G6, iPhone X. Of the cheaper models, we can recommend any of last year’s flagships, for example, or. Among state employees there are also good cameras, for example, y.

What should the battery capacity be?

Predict time battery life smartphone, based only on technical characteristics, impossible. It depends not only on capacity battery, but also on the “gluttony” of the filling, resolution, screen brightness, type of matrix, device optimization and, of course, the mode of its use. That is why we check the operating time and test the autonomy of smartphones using a single method. It would be wrong to give a specific value for battery capacity and say that it is optimal. But we can still give you approximate guidelines for phones based on screen diagonal:

• for a smartphone with a display up to 4 inches, we recommend a battery capacity of at least 1400-1500 mAh;
• for a diagonal of 4-5 inches you will need a battery of 2000 mAh;
• with a screen from 5 to 5.5 inches - at least 2400 mAh;
• For displays larger than 5.5 inches, a battery of at least 3000 mAh is required.

What stands apart from other models are “long-lived smartphones” with huge-capacity batteries, such as the popular ones (5000 mAh) or (4100 mAh). There are also models with a battery capacity of 10,000 mAh, for example.

Do I need to pay attention to the case materials?

If you are buying a device based only on technical characteristics, then you can skip this point. In another case, before purchasing, you should decide what kind of smartphone you want: made of plastic, metal or glass. So which phone should you buy? Let's figure it out in order.

Matte plastic is a commonly used material and is usually smooth. Plastic is inexpensive and practical, it does not leave marks or fingerprints, and if scratches appear, they are almost invisible. This material is used in .

Glossy plastic is a shiny plastic, usually plain, but sometimes with graphic effects on the surface. Such smartphones look impressive at first (especially on a store shelf). However, the “gloss” quickly loses its original appearance - the body becomes covered with fingerprints, greasy stains and scratches, which are clearly visible. Popular smartphones with a glossy plastic body - and.

Polycarbonate- one of the plastic options, externally something between smooth and glossy plastic. A universal material used in most Microsoft smartphones or any others, for example, an old or .

Coated plastic Soft-touch— plastic with a special elastic rubber-like coating that feels like a rubberized surface. Pros - a smartphone with a soft-touch coating is comfortable to hold in your hand; it will not slip out, even if you take it with wet palms. Disadvantages - after six months to a year of active use, the case begins to wear out: the “soft-touch” coating peels off and a surface with simple plastic is exposed. As an example of a device with such a coating, we give.

Metal- usually an aluminum alloy is used, less often - stainless steel. A smartphone in a metal case looks and feels more expensive in the hand than any plastic one. This effect is difficult to describe in words; it is much easier to understand it by simply holding such a phone in your hand. In addition, people always think that such a smartphone is more reliable. There are also disadvantages: painted metal wears out over time - the paint peels off, scratches and dents appear. The most popular smartphones using metal casings are and.

Glass- hardened or simply with increased resistance to scratches and impacts. Used to protect the screen from damage and sometimes as an anti-glare layer. This material is used in almost all modern devices, usually this is Gorilla Glass from the American company Corning, DragonTail Glass from the Japanese Asahi Glass or others. There are smartphones on the market that are covered with glass on both sides, for example, and. It looks beautiful, but such surfaces get dirty and slip easily, and you are unlikely to be happy if you suddenly drop such a “glass” phone.

How productive should a smartphone be?

The performance of a smartphone depends on the processor, the amount of RAM, as well as its firmware and optimization. As a rule, everything modern phones are powerful enough for basic tasks and simple applications. And when buying a mid-level device (for example), you can reasonably expect that it will run any applications and heavy games, perhaps sometimes with graphics limitations.

If you need maximum performance, then take any modern flagship, for example, or. But a noticeable difference with the same “average level” will be noticeable only in the heaviest applications and games. Therefore, when choosing a smartphone, it is not at all necessary to focus only on top-end hardware. By overpaying for the flagship hardware, you are most likely buying a supply for several years in advance. But during this time, the smartphone may well break down, or it will become outdated for some other reason (for example, the manufacturer will stop updating the operating system).

Some limitations and performance problems can only be noticed in the budget segment. Here we would advise focusing on at least 2 GB of RAM and at least four cores in the processor, with operating frequencies from 1.3 GHz, for example, like or. Going lower, you risk experiencing delays in the daily operation of the device.

How much memory should a smartphone have?

Any smartphone has a certain amount of built-in memory for storing user data: music, videos, photos and more. Cheap memory models may have 4 or 8 GB, but we would advise targeting at least 16 or 32 GB. Although today there are models with 64, 128 GB and so on. As an additional option, you may be offered a slot for a microSD memory card, but not all smartphones have it.

How many photos, applications and hours of music will “fit” in a smartphone?

Important: in any smartphone, part of the built-in memory is occupied system files and is not available to the user. The amount of such memory depends on specific model and manufacturer. If the smartphone's specifications indicate 8 GB of memory, approximately 3-6 GB will be available to the user; if 16 GB is specified, approximately 10-13 gigabytes will be available. Before you buy a phone, consider how much memory you need.

16 GB- if you buy a smartphone mainly for making calls, checking email and the Internet, a version with a built-in memory of 16 GB or even less is suitable. The presence of a slot for a memory card will allow you to expand this volume and store additional photos, audio and video.

32/64/128 GB- if you plan to use your smartphone as an MP3 player, store captured photos, play like on game console or make a DVR out of it, it is advisable to choose a phone with a memory capacity of at least 32 GB.

Smartphones with a memory card slot offer another 32 to 200 gigabytes of memory. Moreover, budget models, as a rule, support microSD cards with a capacity of 32-64 GB, and more expensive devices - up to 200 GB. The expanded memory capacity will allow you to use your smartphone to the fullest: play games on it, listen to music, download and watch movies and TV series. But keep in mind that memory cards do not last very long and break easily, that is, one day you can suddenly lose data from it.
