Smartphones are replacing regular phones, but their choice is not easy for most people, because even any simplest smartphone is accompanied by a long list of characteristics that are "extremely important" for the buyer. Let's try to understand and decipher some abbreviations.
So, the most important and expensive part of a smartphone: the display... The cost of the device is mainly determined by this particular module. Screen size is measured along its diagonal length in inches, for example: 5 ". However, in addition to its physical dimensions, its resolution is important, i.e. the number of vertical and horizontal dots that it can display.
The higher the resolution with the same screen diagonal, the better the picture will be. For this parameter, the density of the placement of dots on the screen, the term PPI (points-per-inch, dots per inch) is responsible. Currently popular resolutions for 5 inch screens are HD Ready(1280x720) and Full HD(1920x1080), for the latter, the value is usually indicated PPI about 400-440 units.
If you suddenly come across a smartphone “ big screen»And an unexpectedly low price, pay attention to its resolution, if it is below the listed values, you should not expect a good picture from it. Another important characteristic of the screen is the type of matrix on the basis of which it is made. Ultimately, for a smartphone, this directly affects the quality of color reproduction, how rich and believable the colors will be. At the moment, the best among the displays are matrices of the type IPS and Amoled.
There is an area directly adjacent to the screen that is responsible for the response to pressing - TP(touchpanel). She is characterized by one important parameter: The number of simultaneous presses that the panel can register. This value starts at 2x (for smartphones with a small screen size) and can go up to 10 (typical for tablets). The ability of the touch panel to understand a lot of clicks can come in handy in games, but if you play rarely, two TPs will also be quite enough.
A special glass is now glued over the TP area in modern smartphones, which protects the screen from damage, scratches and others. external influences... It also protects the camera lens on back cover if the manufacturer cares about its users, since this part is even more prone to damage than the screen with which the device is usually placed upside down. If you see a word in the list of characteristics Corning Gorilla Glass 1-2-3 or AGC Dragontail, the conversation is about him.
The 3 components described above are usually made in the form of a one-piece module from plates glued to each other, bearing the name OGS(one-glass-solution). This decision is due to 2 reasons: there is no air between the layers, which distorts the picture if you look at the screen from a non-right angle, in addition, the thickness of the device as a whole decreases, which affects ergonomics. At all modern technology"Full lamination" GFF(glass-to-film-to-film, literally: glass to TP film to screen film) implies that the 3 components are glued together so tightly and efficiently that the screen seems to be at the very top, and not in depth, which attracts the device with its quality pictures and affects the same final case thickness.
V recent times on the above 3 layers, a thin 4th layer was applied, which has the name "oleophobic coating", which is a thin "nano" -film that repels fats from the screen. Another application option is an anti-reflective coating, its meaning is clear from the name.
The next important characteristic of a smartphone is its battery capacity.... Besides the fact that it can be removable and non-removable (affects the thickness of the device as a whole), the main parameter of the battery is its capacity. It is clear that the larger the capacity, the longer the smartphone will work, at the same time, you need to remember that the capacity increases the weight of the device (not everyone is comfortable wearing a brick in their pocket). It should be borne in mind that the main consumer of energy is the screen. If it is large, with high resolution, then he needs more current. But a larger battery can be placed under a larger screen area! Summing up, one cannot say, for example, that a 2000mAh battery is not enough, for smartphones with a small screen diagonal this will be quite enough. For 5-5.5 inch devices, of course, it is better to have a higher capacity, from 2500 mAh, and if it has a 4G communication function (LTE), then from 3000.
Battery charger from the network consists of 2 parts: the actual power supply and the cord. Often people, having bought an additional charger in the nearest store, complain that it somehow charges "badly". This is really a problem, since a smartphone, despite its size, can easily consume 600-800mAh at peak load, so you shouldn't be surprised that after playing games or watching a movie, you find out that after 3-4 hours the battery is discharged. We divide the conditional 2000 capacity by 600 and we get 3.5 hours of work, there are no miracles. Those. the question itself: "How long do you have a smartphone?" is fraught with a catch, if you use it, then it is obvious that it will not last long, and if you do not use it, the question arises of acquiring a toy with so many functions, most of which are not used in any way. Since the smartphone consumes current in such a volume, the charger should produce it significantly more. Now on the market, the minimum current value issued by the charger is 1A. If you connected your smartphone to a new unit for charging and it charges "somehow wrong", touch it, it should not be hot. High temperature is detrimental to the battery, most likely overheating means that the declared characteristics of the output current do not correspond to the real ones. If there is no replacement at hand, reduce the consumption of your smartphone, charge it with the screen off, or turn it off altogether for a while.
Many modern smartphones support technology quick-charge (fast charging), which allows you to speed up the battery charging process (the stated numbers are up to 40%), such units usually give out 2A at the output (at 5V voltage). A separate important point is the quality of the power cord, which has its own resistance, which ultimately affects the value of the current coming to the smartphone connector. If the cord is bad, even the highest quality Charger may be ineffective.
As for charging from a computer / laptop: the USB 2.0 standard allows you to power devices with a current of up to 500mA, 3.0 - up to 900mA, respectively, charging from an old computer will be ineffective, or even vice versa, cause the smartphone to discharge.
Smartphone Now it is very difficult to see a person without mobile phone... Especially the one who takes pictures, goes online, shoots videos, works with documents, etc. In this article we will talk about a smartphone and what functions it has.
Smartphone from English translation means "smart phone".
The main functions of the smartphone:
- it has the ability to access the Internet;
- you can take videos and photos, as well as a voice recorder;
- you can play video and audio;
- communicate on e-mail;
- available GPS navigator;
- various records: memos, contacts, lists, databases.
- all kinds of games;
- you can work with office applications;
- of course, you can make calls, SMS, MMS;
The smartphone also has disadvantages:
- these sometimes include the size of the phone, since the display is 5 inches and it is not very convenient to put it in one hand anymore.
- many smartphones discharge quite quickly;
- when using such a phone, you need to be careful. If the screen is large, it will stop working when dropped.
- many smartphones are sensitive to environment... For example, if the temperature is below zero, the screen may freeze and not be pressed. If it is too hot, condensation will form under the screen.
- those who developed this phone want to know everything about you. And all the time, when installing various programs, request personal information from you.
- modern gadgets cause addiction in people.
- people who do not understand anything in technology will find it difficult to understand the phone menu.
Characteristics of smartphones
1. Manufacturer. First of all, when buying a phone, a person looks at the manufacturer. Indeed, even with the same characteristics, the device can work in different ways and differ in speed. The leading smartphones are: Apple, Samsung, HTC, Lenovo, Nokia, Sony, LG.
2. The number of SIM cards. Previously, when a person had several SIM cards, he had to open the phone cover and change them all the time. And now there are many models with two slots.
3. Display. The screen has several indicators
Is the diagonal. Choose a display that fits comfortably in your hand.
- type of matrix. The most famous are AMOLED, super AMOLED and IPS. To each his own.
- screen resolution. The bigger, the better.
- the screen has protective film, with which you can avoid the ingress of dust and moisture.
- there is a special glass that can protect the screen from scratches.
4. Processor. All smartphones, like a computer, have a "brain". The processor comes in 1,2,4,8 and 16 cores. The speed of your phone depends on the number of cores.
5. Random access memory. This characteristic affects the speed of all applications, watching a movie.
6. Permanent memory. This is the amount of information you can store on your phone. If there is not enough memory, then before recording, you will have to delete something. It is best if the internal memory is at least 8 GB.
7. Internet connection. Connected via 3G / 4G modules, standard mobile operators or using wireless wifi module.
8. Camera. There are smartphones with one or two cameras. Front and back.
9. Charge your phone. Battery capacity is measured in mAh (mAh). if this indicator is large, then the phone will work for a long time. Many smartphones have 1800 to 3500 mAh battery.
10. Can be expanded internal memory... Increase memory with a USB flash drive. When you choose this device, pay attention to its class affiliation .. The higher the class, the faster the flash drive will work.
11. Design. Choose the design you like. You can put a funny case on your phone.
Additional phone options
It all depends on the manufacturer, many have additional functions:
FM radio;
You can connect a function where the phone is activated using fingerprints.
LED flash;
A program that edits videos and photos;
Standard programs - calendar, alarm clock, weather, and much more ..
Have you seen touch screens 55 inches diagonal? Such touchscreen kiosks (information terminals) can be installed in airports and shopping centers. The main task of such screens is to convey information to the consumer. You also constantly encounter them when various payments in retail outlets.
Xiaomi was able to quickly gain a large customer base by offering smartphones to the market High Quality on reasonable price... But initially the lineup Xiaomi was not as diverse as its main competitors, and it was obvious that the Chinese manufacturer would be developing new phone models for the foreseeable future.
To date, the Xiaomi lineup has become very diverse, but at the same time, you can easily understand the features of a particular branch of smartphones, unlike, say, competitors such as Meizu or Samsung.
In order to make it more convenient for you to choose the suitable version of the Xiaomi phone for yourself, we suggest comparing all the models that have come out of the company at the moment, finding similarities and differences in them, and, thus, deciding on the competitive advantages of each.
Widget from SocialMartIf we want to compare Xiaomi based on all known models of the company's gadgets, then we can distinguish three main lines: 
For convenience, each of the lines can be subdivided into several more categories, which we propose to do now in order to fully compare Xiaomi across all models on the market.
Features of the Mi line
In general, we recommend considering the Mi line in three main branches. We compare them in the table for ease of understanding.
| Branch name | List of models | Peculiarities |
|---|---|---|
| Xiaomi Mi |
|
There is only the best hardware and a 5-inch screen with slight deviations in the larger side in some models. Models from Xiaomi Mi 1 to Xiaomi Mi 3 are no longer relevant, although it was with them that the conquest of the market by this Chinese company began. For the summer of 2011, when the first model in this line appeared, the 8MP camera, dual-core processor and 1.5GB RAM were impressive figures. Today, models starting from the "four" and higher are relevant. Mi 4 with a diagonal of 5 inches, a camera of 13 megapixels and 3 GB random access memory became a discovery in 2014, and its technical characteristics are relevant to this day. The developers realized that the model was becoming more and more popular, and therefore released three more "fours" with minimal differences, but only the Mi 4 version turned out to be successful. In 2016, the Mi 5 finally came out, which surpassed all the "fours" in quality. She had a 16 megapixel camera, powerful Snapdragon processor 820 and comfortable and attractive design. Later, the S-version of the "five" came out with an even larger battery capacity and clock frequency processor. The newest Mi model at the moment is the "six". It's still cooler here: 6 gigabytes of RAM, two excellent cameras (even the front one has 8 megapixels) and the Snapdragon 835 processor - the best among all Xiaomi. In 2016, the original model Mi Max was also released, the "chip" of which was a huge screen with a diagonal of 6.44 inches with the competitive characteristics of the filling. |
| Mi Note |
|
The difference between Note models lies in the large screen diagonal. Xiaomi Mi Note is, in fact, the twin of Xiaomi Mi 4, but with a 5.7-inch screen. Mi Note 2 is not much different from its predecessor, but it has a slightly larger diagonal and various additional bells and whistles like a fingerprint scanner. |
| Mi Max |
|
The similarity with Mi Mix is noticeable to the naked eye - the 6.44-inch screen diagonal allows you to call this branch a classic "shovel". The indicators "under the hood" are far from flagship, so you should choose this option only if you really like the larger monitor size. |
Features of the Xiaomi Redmi line
We also propose to carry out a comparative analysis of the "state employee" on the basis of the table:
| Branch name | List of models | Peculiarities |
|---|---|---|
| Xiaomi Redmi |
|
These smartphones are the most compact of all with a screen diagonal of up to 5 inches. Initially, a polycarbonate case was used, but starting from the "three" is installed metal case and there is a fingerprint scanner. All Xiaomi smartphones from the Redmi series that came out later have improved qualitatively, and looking at their characteristics, you can't even say that they are "state employees". |
| Xiaomi Redmi Note |
|
As with the Mi, the addition of Note to the name speaks to the enlargement of the screen. Starting with Redmi Note 3, Xiaomi phones are produced in premium style, have an aluminum casing and got a fingerprint scanner. |
Features of the MiPad line
It is easier to make comparisons between Xiaomi tablets - only three models came out here. Xiaomi Mi Pad was trial version to see if the tablet will be as popular as smartphones. It turned out that everything is in order, and therefore the Chinese launched the Xiaomi Mi Pad 2, from which they firmly established themselves in this niche on the market.
The differences between the first and second models are visible to the naked eye. The body of the "deuce" is made of metal, not polycarbonate, operating system you can choose between Android and Windows 10.
Xiaomi Mi Pad 3 has gone even further - here it will already be possible to choose between two basic configurations that differ in the amount of built-in and operating memory: 3 GB of RAM with 64 GB of built-in or 4 GB of RAM with 128 GB of built-in. The chipset has also been improved in comparison with the more budgetary "two" - instead of Intel Atom X5-Z8500 appeared Intel Atom X7-Z8700.
What to give preference to?
Before choosing a particular model smartphones Xiaomi decide why you need a phone. If you plan to use it in everyday life or for business, then you can safely choose one of the "state employees", saving money and getting a completely high-quality product for the invested funds. If you want to follow the latest fashion trends, trying out every newly released game, then it is better to immediately consider one of the flagship Mi smartphones.
Besides the price, one of the parameters for evaluating Xiaomi's compliance with your expectations will be the screen size. There is a lot to choose from - from small and stylish business models to "shovels" with a huge monitor. If you are just attracted to the "shovels", then it is very easy to find them - find a name that contains Note, Mix or Max, and after that it remains only to decide on the preferred technical characteristics of the device.
What parameters influence the buying decision when choosing a new phone? Camera, display resolution, performance or additional features suggested by the developers? The main characteristics of a smartphone are certainly important, but the main selection criterion for the majority is battery autonomy. Nobody wants to go around with a discharging phone and live "from socket to socket"!
Performance is the second most important characteristic of a smartphone for more than half of users. The list of main parameters also includes: price, software and screen diagonal. And now, after we have answered the main question of the publication, I propose to talk about these layers of the smartosphere in more detail.
The main characteristic of the smartphone: battery autonomy
A few years ago, we all used phones with a battery of about 2000 mAh and were generally satisfied. At the time of publication, I counted in 29 models with a 5000+ mAh battery capacity. If we apply a 4000 mAh or more filter, we get 101 samples. The record holder is generally equipped with some kind of portable power station - 12000 mAh!
The battery has really become the main feature of the smartphone. Today in any more or less self-respecting mall there is a zone for recharging the phone. Almost every active user always and everywhere carries a charging cord with him, and many also carry a portable charger.
What explains such a depressing situation with autonomy in the era of the rapid development of other basic parameters of smartphones? There are several reasons. First, the load on the computational core has grown. Yes, processors are manufactured in 16nm and 14nm process technology, but another problem has arisen: the number of applications is growing exponentially.
Additional functions appear in smartphones, which are not always useful, but they work non-stop and consume energy. The amount of RAM has increased. Someone will say that this is great! RAM capacity - important characteristic smartphone, but increasing it has a side effect: Android or iOS leaves the application in active mode, even if you have not used it for a long time, and the application consumes energy.
Developers have stopped optimizing software. What for? There is already enough memory, you can spend it right and left. The same Twitter “sits” on the Internet all day and night and eats battery power. Messengers and applications behave in the same way. social networks, and this negatively affects the autonomy of the phone.
Let's add an increase in the screen diagonal with a sharply increased number of pixels, and we get an explosive mixture that kills the battery charge. In short, you won't go far without recharging. It shouldn't be surprising that autonomy is the main characteristic of a smartphone for 67% of users. 
If you want to increase the autonomy of an electronic friend, stop applications often (Force Stop) in forced mode and disable unnecessary functions, especially in branded casings like MIUI or TouchWiz.
Key features of smartphones: performance
One of the main characteristics of smartphones for 61% of users is performance. Performance affects the user experience directly: we want the interface to be responsive to our actions, switching between applications was smooth, and their start - instant. For gamers, smartphone performance is generally main criterion choice, because if the phone does not support the game, why is it needed then?
The choice of really smart phones today is very large. Huawei managed to break into the elite with the release of the very cool Mate 9 on the Kirin 960 chipset, which is in many ways not inferior to the flagships. It's unnecessary to talk about the capabilities of the Apple A10 Fusion and Exynos 8890. As for Qualcomm's top processor in 2016, the Snapdragon 821, its potential is also well known. 
Since the main characteristics of smartphones for more than half of users are autonomy and performance, the “ideal device” should be equipped with a top processor and a cool battery. And there are some on the market.
