Comparison Realme 11 4G 256 GB / 8 GB vs Realme 10 128 GB / 8 GB

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).

The ratio of the screen area to the total front panel area of the phone. Simply put, this spec describes how much of the front panel is occupied by the screen; the rest is the bezels.

This indicator is given exclusively for smartphones with touch screens — it is for them that it is most relevant. The larger the percentage of the body is occupied by the screen, the thinner are the bezels, the neater the smartphone looks and the more convenient it is to work with it with one hand. As for specific numbers, the average values are 80 – 85 %, the higher values allow us to talk about a thin bezel, and more than 90 % — about a “bezel less” design.

Separately, we note that this parameter has nothing to do with the aspect ratio of the screen. The aspect ratio describes only the display itself — its proportions, the ratio between the larger and smaller side of the rectangle.

The type of RAM installed in the smartphone.

All modern devices use LPDDR format RAM ( LPDDR4, LPDDR4x, LPDDR5, LPDDR5x, LPDDR5T). In addition to its miniature size, it differs from conventional computer RAM in supporting special data transfer formats (16- and 32-bit memory buses). But versions of such memory can be different:

- LPDDR3. The earliest current generation of LPDDR was introduced in 2012 and has been implemented in devices since 2013. Standardly operates at speeds up to 1600 MT/s (megatransactions per second) and frequencies up to 933 MHz; The “improved” version supports speeds up to 2133 MT/s. Nowadays, this standard is rarely found, mainly among outdated mobile devices.

- LPDDR4. The successor to LPDDR3, officially introduced in August 2014 (although the first hardware developments were released at the end of 2013). The operating speed, compared to its predecessor, has doubled - up to 3200 MT/s; frequency increased to 1600 MHz; and energy consumption was reduced by 40%. In addition, the data transfer format has changed - in particular, instead of one 32-bit bus, two 16-bit buses are used, and some security improvements have been introduced into the standard. This memory can be found in some medium-range smartphones. - LPDDR4x. An improved versio...n of LPDDR4 with reduced power consumption - the standard uses a voltage of 0.6 V instead of 1.1 V. In addition, some improvements were implemented in this type of RAM aimed at increasing speed (it reaches 4266 MT/s) and general optimization of operation - for example, a single-channel mode for undemanding applications. Thanks to such characteristics, this version of memory has become noticeably more widespread than the original LPDDR4. You can find it in mid- and high-end devices.

- LPDDR5. Further development of “mobile” RAM, officially announced at the beginning of 2019. The operating speed in this version is increased to 6400 MT/s, a differential signal format was introduced to improve resistance to interference and errors, and dynamic frequency and voltage control was introduced to reduce power consumption. The use of such memory modules is typical mainly for high-end smartphones.

- LPDDR5x. A more energy efficient and faster version of LPDDR5 RAM. The data transfer speed in it was increased to 8533 MT/s, and the peak throughput indicator was increased to 8.5 Gbit/s. The number of memory banks per channel in LPDDR5x is always 16. RAM of this standard is typical for advanced smartphones of the highest grade.

- LPDDR5T. T is for turbo. The operating speed of the LPDDR5T standard RAM has been increased to 9600 MT/s, and devices with such memory modules are about 13% faster compared to LPDDR5X. The memory operates in the low voltage range from 1.01 to 1.12 V. The corresponding modules are aimed at use in high-end mobile devices.

The volume of storage installed in the phone.

This volume directly determines how much data can be stored on the phone without using removable memory cards. This indicator is especially important for models that don't have memory card slots. However, even if memory cards are supported, built-in storage is still preferable: at least it works faster, and it usually has fewer restrictions on its use (in particular, most smartphones allow you to install applications only on storage).

As for specific volumes, the actual minimum for a modern smartphone is 32 GB; less “capacious” devices are becoming increasingly rare these days. 64 GB is considered a comfortable minimum, 128 GB is considered average indicator, 256 GB - above average. Some high-end devices are equipped with 512 GB and even 1 TB< /a>.

We also note that the actual amount of memory available to the user will inevitably be somewhat less than the total, since part of the drive is occupied by operating system files.

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.

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%.

The result was shown by the device when passing the Wild Life (Extreme) performance test (benchmark) from 3DMark.

The Wild Life (Extreme) benchmark offers two ways to test graphics performance: a quick test that evaluates instantaneous performance, and a longer test that subjects the device to sustained load. This way one can evaluate how stable performance remains and does not drop due to overheating or throttling. The benchmark is cross-platform, which makes it possible to compare devices running different OSs and even different classes (for example, smartphones and laptops).

It is important to understand that this test does not provide absolute accuracy. The same device can show different results — they depend on many factors not directly related to the system. The error caused by these factors is often on the order of 5–7%. So we can talk about a significant difference between the two models being compared if the difference in performance goes beyond the mentioned error.

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 le...vel 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.

The resolution and maximum frame rate provided by the phone's main camera when recording Full HD (1080p) video at normal speed, without slow motion (if available).

The standard resolution for this format is 1920x1080; but there are other resolution options, though they are almost never found on mobile phones. Note that this can be either the maximum resolution or one of the relatively simple options in addition to more advanced standards (such as UltraHD 4K). At the same time, Full HD is considered a decent resolution by modern standards, and at the same time, it can be supported even by fairly simple and inexpensive smartphones.

As for the frame rate, there are actually two options: — Full HD 30 fps and Full HD 60 fps. A higher frame rate allows you to achieve very smooth dynamic scenes — even fast-moving objects are seen as clearly as possible, with almost no blurring. However, 30 fps also have its advantages — it allows you to reduce the size of videos shot. Therefore, in smartphones with 60fps support, it may be possible to reduce the frame rate to 30 fps. Speeds above 60 fps are used for shooting slow-motion video (slow-mo); see "Slow-mo" for more on this.
