Brightness
The maximum brightness in nits provided by the smartphone display.
The brighter the display, the more readable the picture remains on it under intense ambient light (for example, outdoors on a clear sunny day). Also, high brightness is important for the correct displaying of HDR content. However, a large amount of brightness affects the cost and power consumption of the screen. Manufacturers can specify standard, maximum, and peak brightness values. At the same time, an equal sign cannot be put between the maximum and peak brightness. The first indicates the ability of the screen to produce the specified brightness over its entire area, while the peak one — in a limited area and for a short time (mainly for HDR content).

Knowing the name of the CPU model installed in the smartphone, you can find detailed data on a particular CPU and evaluate its level and general capabilities. This is especially true in light of the fact that these capabilities depend not only on the number of cores a
...nd clock speed, but also on the specific nuances of the design.CPU frequency
The clock frequency of the CPU that the device is equipped with. For multi-core processors, which are standard in modern smartphones, the frequency of each individual core is implied; and if the processor has cores with different frequencies (see "Number of cores") — usually, the maximum indicator is given.
In general,
high performance smartphones have high frequency of the processor. However, note that this parameter itself is not directly related to the capabilities of the CPU: many other features of the chip affect the actual performance, and often a low cost solution with a higher clock speed turns out to be less performant than an expensive one, and at the same time, presumably, more "slow" processor. In addition, the overall performance of the system directly depends on a whole set of other factors — primarily the amount of RAM. Therefore, when evaluating a smartphone, it is worth focus not so much on the frequency of the processor, but on the general specs of the system and visual indicators like the results in tests (see below).
Processor rating
End-to-end processor rating (regardless of chipset manufacturer) for Android smartphones. It is based on a set of maximum performance indicators of the processor itself, the memory bus, the graphics core, etc. Processor ratings can be useful to enable comparison and easy selection of similar models.
GPU
The model of the GPU used in the mobile phone.
This module is responsible for all tasks related to graphics; accordingly, its specs directly affect the efficiency of processing a particular picture. This is especially noticeable in the example of modern 3D games. Therefore, the presence of a powerful video adapter is especially important for
gaming smartphones. And knowing the model of the GPU, you can find detailed data about it and evaluate its capabilities.
Max. memory card storage
The largest volume of memory card with which the phone supports. For more information about the cards themselves, see "Memory Card Slot"; here we note that capacious cards often use advanced technologies that are not supported by all devices, and sometimes phones simply do not have enough power to process large amounts of data. Therefore, for the convenience of choosing in our catalog, the maximum supported volume is indicated.
In fact, there are cases when some devices may exceed the claimed characteristics. However, it is worth focusing on official data, because, if officially supported volume is exceeded, normal operation of the card is not guaranteed.
Test results
The test results are specified either by a younger model in a line or a particular model, made for a better understanding performance of phone models if you compare phones against these parameters. For example, the 128 GB model has test results, and the 256 GB model has no information on the network, and in both models you will see the same value that will give an understanding of the overall performance of the device. But if the editorial office has information for each model individually, then each model will have its test results filled out, and the model with bigger RAM will have bigger values.
AnTuTu Benchmark
The result shown by the device when passing the AnTuTu Benchmark performance test.
AnTuTu Benchmark is a comprehensive test designed specifically for mobile devices, primarily smartphones and tablets. It checks the efficiency of the processor, memory, graphics and I/O systems, thus providing a fairly visual impression of the capabilities of the system. The better the result, the more points are given at the end. And
high-performance by AnTuTu rating are smartphones that score over 750K points
Like any benchmark, this test does not give absolute accuracy: the same device can show different results, usually with deviations within 5 – 7%. These deviations depend on many factors that are not directly related to the system — from the load of the device with third-party programs to the air temperature during testing. So, it is possible to speak about a significant difference between the two models only if the difference in their indicators goes beyond those 5 – 7%.
Main lens
Specifications of the main lens of the rear camera installed in the phone. In models with several lenses (see “Number of lenses”), the main one is responsible for basic shooting capabilities and does not have a pronounced specialization (wide-angle, telephoto, etc.). Four main parameters can be indicated here: resolution, aperture (
high aperture optics are quite common), focal length, additional sensor data.
Resolution(in megapixels, MP)
Resolution of the sensor used for the main lens. Budget options are equipped with a module
8 MP and
below, many models have
12 MP camera /
13 MP, also recently a trend towards increasing megapixels has been popular. Often in smartphones you can find the main photomodule at
48 MP,
50 MP< /a>, 64 MP and even
108 MP .
The maximum resolution of the resulting image directly depends on the resolution of the sensor; and the high resolution of the "picture", in turn, allows you to better display fine details. On the other hand, an increase in the number of megapixels in itself can lead to a deterioration in the overall image quality - due to the smaller size of each individual pixel, the noise level increases. As a result,
...the direct resolution of the camera has little effect on the quality of the shooting - more depends on the physical size of the matrix, the features of the optics and various design tricks used by the manufacturer.
Aperture
Aperture describes the ability of a lens to transmit light. It is written as a fractional number, for example f/1.9. Moreover, the larger the number in the denominator, the lower the aperture ratio, the less light passes through the optics, all other things being equal. For example, an f/2.6 lens will be “darker” than f/1.9.
High aperture gives the camera a number of advantages. First, it improves the quality of shooting in low light. Secondly, it's possible to shoot at low shutter speeds, minimizing the effect of "stirring" and blurring of moving objects in the frame. Thirdly, with fast optics it is easier to achieve a beautiful background blur ("bokeh") — for example, when shooting portraits.
Focal length(in millimetres)
The focal length is a distance between the sensor and the centre of the lens (focused to infinity), at which the most clear image is obtained on the matrix. However, for smartphones, the specifications indicate not the actual, but the so-called equivalent focal length — a conditional indicator recalculated using special formulas. This indicator can be used to evaluate and compare cameras with different sensor sizes (the actual focal length cannot be used for this, since with a different sensor size the same real focal length will correspond to different viewing angles). (It is also worth saying that the equivalent focal length can be noticeably larger than the thickness of the case — there is nothing unusual in this, since this is a conditional, and not a real indicator).
Anyway, the field of view and the degree of magnification directly depend on the equivalent focal length: a larger focal length gives a smaller field of view and a larger size of individual objects that fall into the frame, and a decrease in this distance, in turn, allows you to cover more space. In most modern smartphones, the focal length of the main camera ranges from 13 to 35 mm; if compared with the optics of traditional cameras, then lenses with equivalent focal length up to 25 mm can be attributed to wide-angle lenses, more than 25 mm — to universal models “with a bias towards wide-angle shooting”. Such values are chosen due the fact that smartphones are often used for shooting in cramped conditions, when a fairly large space needs to fit into the frame at a small distance. Enlargement of the picture, if necessary, is most often carried out digitally — due to the reserve of megapixels on the sensor; but there are also models with optical zoom (see below) — for them, not one value is given, but the entire working range of the equivalent focal length (recall, optical zoom is carried out by changing the focal length).
Field of view(in degrees). It characterizes the size of the area covered by the lens, as well as the size of individual objects "seen" by the camera. The larger this field, the more of the scene gets into the frame, but the smaller the individual objects in the image are. The field of view is directly related to the focal length (see above): increasing this distance narrows the field of view of the lens, and vice versa.
Note that this parameter is generally considered important for professional use of the camera rather than for amateur photography. Therefore, viewing angle data is given mainly for smartphones equipped with advanced cameras — including in order to emphasize the high class of cameras. As for specific values, for the main lens they usually are in the range from 70° to 82° — this corresponds to the general specifics of such optics (universal shooting with an emphasis on general scenes and extensive coverage at short distances).
Additional Sensor Data
Additional information regarding the sensor installed in the main lens. This item can specify both the size (in inches) and the sensor model, and sometimes both parameters at once. Anyway, such data is provided only if the device is equipped with a high-end sensor. With the model, everything is quite simple: knowing the name of the sensor, you can find detailed data on it. The size is worth considering a little more.
The size of the sensor is traditionally indicated in fractional parts of an inch — accordingly, for example, a 1/2.3" sensor will be larger than 1/2.6". Larger sensors are considered more advanced, as they provide better image quality at the same resolution. The logic here is simple - due to the large sensor area, each individual pixel is also larger and gets more light, which improves sensitivity and reduces noise. Of course, the actual image quality will also depend on a number of other parameters, but in general, a larger sensor size usually means a more advanced camera. In advanced photo flagships, you can find matrices with a physical size of 1”, which is comparable to image sensors used in top compact cameras with fixed lenses.
