DCI-P3

Percentage of the DCI-P3 colour model coverage by a smartphone screen.

This space has a wider range of colours than the standard sRGB "triangle". In general, the DCI-P3 colour space corresponds to the Adobe RGB model, but with a shift to red. In fact, a high coverage rate means high-quality colour reproduction of the screen and allows finer processing of the images received from the camera of a mobile device.

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 AnTuTu

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.

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.

Navigation

Navigational features provided by a device, usually a smartphone.

It is almost mandatory for a modern smartphone to have a GPS module and a digital compass. In addition, aGPS is often provided to speed up work, and Dual GPS to improve accuracy. Here is a more detailed description of these features:

— aGPS. An auxiliary feature that allows you to speed up the start of the main GPS receiver. To work for its main purpose, such a receiver must update data on the location of navigation satellites; Obtaining this data in the classical way, directly from the satellites themselves, can take quite a long time (up to several minutes). This is especially true for the so-called "cold start" — when the receiver starts up after a long break in operation, and the data stored in it has become completely outdated. aGPS (Assisted GPS) allows you to receive up-to-date service information from mobile network — from the nearest base station (this feature is supported by most mobile networks nowadays). This can greatly speed up the startup process.

— GPS module. Navigation module that allows you to determine the current coordinates of the device through the GPS satellite navigation system. GPS is the oldest and most common of these systems. The standard accuracy of modern receivers of this standard is about 6 – 8 m, and with the use of special technologies — several decimetres. As for the GPS-mod...ules in phones, they only provide the current location; How this data is used may vary depending on the operating system and installed applications. Among the most common options are map navigation (including track recording), geotagging photos and posts on social networks, searching for various objects nearby (attractions, transport stops, shops, hotels, cafes / restaurants, emergency services, etc.) , displaying the user's location (for example, to a taxi or delivery service), etc.
Notes to this paragraph may indicate additional systems supported by satellite receivers — for example, the European Galileo system. The exception is the Russian GLONASS, compatibility with which is specified separately (see below).

— Dual GPS. Additional feature found in modern GPS receivers (see above). Such receivers do not operate at one frequency, like traditional modules, but at two ("L1 + L5") — thus receiving two signal packets at once and comparing them with each other. This type of work significantly improves positioning accuracy — in some cases up to 10 – 20 cm. In addition, Dual GPS allows you to correctly process signals reflected from tall buildings — this increases efficiency in dense urban areas. However, it is worth noting that it is not always possible to use all the advantages of this feature. Full support for L5 is available only in the European Galileo system; in GPS (as of 2020), only about half of the satellites carry out such broadcasting, and in GLONASS it is not expected before 2030. In addition, compatibility may be limited by the capabilities of the smartphone: for example, in some models, Dual GPS mode becomes available only after a firmware update.

— GLONASS. Ability to use the GLONASS satellite navigation system. It is a Russian alternative to the American GPS, also providing global coverage. In standard mode, it almost does not differ in accuracy from GPS (about 5 – 10 m), but in special modes it is noticeably inferior (2.8 m versus 30 cm). Therefore, in modern smartphones, GLONASS is practically not used as the main navigation system — usually compatibility with it is provided as an additional feature of the GPS module. The ability to receive signals from two satellite systems at once has a positive effect on the quality of navigation, especially in dense urban areas, indoors and in mountainous areas: the number of dead zones decreases, the satellite search time decreases, and positioning accuracy improves.

— Galileo. European satellite navigation system, created as an alternative to the American GPS. Note that it is under the control of civilian departments, not the military. With a full fleet of 24 active satellites, the system gives an accuracy of up to 1 m in public mode and up to 20 cm with the GHA service. Working in conjunction with GPS, the Galileo system provides a more accurate position measurement, especially in densely populated areas.

— Digital compass. An electronic analogue of a conventional compass: a module that allows you to determine the direction to the cardinal points. Usually, it uses the same principle of operation, and the design is based on a miniature magnetic sensor. Along with the GPS module, it is an almost mandatory feature for modern smartphones. However digital compasses for the most of them are not accurate — but this drawback is not critical, since in the case of a smartphone, such accuracy is extremely rarely required.

Battery life (PCMark)

Because manufacturers claim a very conditional battery life (in an unknown mode, with unstated brightness indicators and phone settings) in the specs of their gadgets, which is more marketing and is not confirmed in reality, we decided to display a more accurate picture. The operating time indicated in this paragraph is the result of the PCMark Work 2.0 Battery Life benchmark, which evaluates energy efficiency in five work formats: web surfing, video viewing/editing, photo editing, working with text documents and working with data (extracting them from different file formats, building charts). These are the main tasks that a smartphone is supposed to perform in everyday life. And thanks to this testing format, the results very accurately correspond to the actual battery life of the gadget with active use during the day.

Bezel/back cover material

The materials of which the bezel (side edging) and the back cover of the device are made.

In our catalog, this data are indicated in two words — frame material and cover material. For example, a device with a glass back and metal edging would be labeled as "metal/glass" (bezel first, then lid). Two words are specified even if the same material is used for both elements — for example, "metal/metal" for an all-metal case.

The main bezel materials include plastic, metal, glass, rubber, and ceramics. Back covers are also made mainly of plastic, metal, ceramics or rubber, and among glass there is a special variety — Gorilla glass parts. Occasionally, more specific materials are used, such as leather. Here is a more detailed description of each of these options:

— Plastic. A fairly simple, inexpensive and at the same time versatile and practical material. Actually, nowadays there are many varieties of plastic on the market, which differ in price and practical properties; so that the general property of this material depends primarily on the price category of the device. The easiest...way to give cover an unusual design is using plastic, although this design is also found in other materials. In general, all types of plastic in modern phones can be divided into glossy, matte, fluted and soft-touch. The gloss looks the shiniest, but dirt is very noticeable on it (first of all, fingerprints), moreover, such cases tend to slip in the hands. Matte surfaces are not as good-looking, but they are less sensitive to dirt. Soft touch is a special kind of matte plastic: due to the specific surface texture, this material is perceived as soft to the touch, similar to rubber. Also, it is perfectly held in the hands and almost does not slip. Fluted plastic is considered the most reliable in this regard — with signature notches on the surface; however, not everyone likes the look and feel of such surfaces when held.
As for combinations with other materials, plastic frames can be provided in metal and glass cases — for a secure hold; and plastic covers can be supplemented with metal or rubber frames for increased reliability.

— Metal. Usually metal most often means aluminium alloy. This material combines high strength, low weight and good thermal conductivity (the latter is especially important for removing heat from the hardware of performant smartphones). Metal cases are relatively rarely made in bright colours, but such a design is also possible; in addition, even without additional coloring, this material looks good. In general, it costs more than plastic, but nowadays even low cost phone models can be made of metal. At the same time, the metal frame can be combined with almost any cover material, however, such frames are especially popular in models with a glass back panel — the metal gives the case additional strength. Metal covers are found mainly among all-metal cases, less often in combination with a plastic frame (it allows you to reduce the cost and improve the permeability of the case for communication signals).

— Glass. Phone cases usually use special tempered glass of increased strength (a special kind of such glass — Gorilla Glass — is indicated separately, see below). Theoretically, glass is more sensitive to shock than most other materials, but in fact it is still quite difficult to break such a surface. At the same time, these cases look quite stylish and unusual. Their disadvantages include a rather high cost, as well as the signature features of glossy surfaces — the tendency to slip out of hands and "collect" dirt, especially fingerprints. In terms of specific body parts, glass is most often used for back covers; they are often complemented by frames made of more durable material (usually metal). But glass frames are usually part of all-glass cases — other design options do not make sense for a number of reasons.

— Gorilla Glass. A special type of high-strength glass from which back covers can be made. For glass in general, see above; and Gorilla Glass features are detailed in the Main Display section. We only note that, as in displays, different versions of such glass can be used in the rear panels of the case, differing in resistance to shock and scratches.

— Rubber. Usually, in this case we are talking about a body or a frame made of a hard material (plastic or metal) with an additional rubber coating. The use of such a coating is an unmistakable sign of a phone with a high degree of protection — waterproof, and often also shockproof. Rubber is the optimal material for such devices: it perfectly resists both moisture and shock, well insulates the hardware from cold and heat, while such a surface is pleasant to the touch and does not slip in the hand. The main drawback of this material is its bulkiness: the rubber coating must be quite thick, so that it noticeably affects the dimensions of the device. Thus, it makes sense to pay attention to this option in occasions where security is more important for you than compactness. At the same time, we note that the rubber case can be combined with a metal frame, and the rubber frame can be installed on a plastic device; these options also turn out to be quite reliable.

— Ceramics. Ceramics is material made by sintering raw materials at high temperatures. Mobile phones use special high-strength types of such materials. The advantages of ceramics include a stylish appearance and good reliability in most situations. On the other hand, such compositions are still quite sensitive to impacts (especially point impacts), they tend to slip in the hands, and they are not cheap. Therefore, ceramics is rarely used in modern mobile phones — mainly as a fashion material in fairly advanced models. Most of these models combine a ceramic lid with a metal frame; all-ceramic cases are noticeably less common.

— Leather. A rather rare and specific material, used mainly as a design solution. Leather covering in such cases is provided for the back cover, while the frame is made of metal or plastic. This material gives the device a solid appearance, emphasizing the status of the owner; in addition, it is pleasant to the touch and does not allow the device to slip out of the hand. However, leather is expensive and not reliable: it is easily scratched and torn even with light contact with sharp objects, and is also prone to abrasion. Therefore, such cases are not popular even among high-end phones.
