DxOMark test (display)
DxOMark is an independent private research and development centre, which operates a department for evaluating the quality of mobile phone screens. DxOMark tests smartphone displays for comprehensive analysis, from image clarity and responsiveness to artifacts and rendering issues. After passing the test, the smartphone is assigned points for the quality of the screen.
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 a device when undergoing a performance test (benchmark) in AnTuTu Benchmark.
AnTuTu Benchmark is a comprehensive test designed specifically for mobile devices, primarily smartphones and tablets. It evaluates the efficiency of the processor, memory, graphics, and input/output systems, providing a clear impression of the system's capabilities. The higher the performance, the more points are awarded. Smartphones that score over 900K points are considered
high-performance according to the AnTuTu ranking.
Like any benchmark, this test does not provide absolute precision: the same device can show different results, usually with deviations within 5-7%. These deviations depend on various factors unrelated to the system itself, such as the device's load from third-party programs and the ambient temperature during testing. Therefore, significant differences between two models can only be noted when the gap in their scores exceeds this margin of error.
Geekbench
The result shown by a device when undergoing a performance test (benchmark) in Geekbench.
Geekbench is a specialized benchmark designed for processors. Since version 4.0, it also includes tests for graphics processors, and by the end of 2019, version 5 of the benchmark was released. Typically, the specifications for portable gadgets include data specifically for the CPU. During testing, Geekbench simulates workloads that occur during real-world tasks, evaluating both single-core performance and the efficiency of multi-core operations. This provides a solid overview of the processor's capabilities in everyday use. Additionally, Geekbench is cross-platform, allowing for comparisons between the CPUs of different devices (smartphones, tablets, laptops, PCs). In reference materials, only the multi-core test results for the processor are usually provided.
Wild Life (Extreme)
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.
Form factor
The form factor of the front camera determines, first of all, the features of its location.
Nowadays, you can find such form factors of such cameras:
teardrop,
notch,
retractable,
in the display (island),
under the display (hidden). Here is a more detailed description of these options:
— Teardrop. The camera is located in a signature cutout on the top side of the display. Such a cutout is small (slightly larger than the module itself) and is shaped like a drop hanging from the top edge of the screen — hence the name. Thanks to this arrangement, the camera takes up very little display space, and most devices with this feature have a very large screen-to-body ratio (see above) — 80% or more (although there are exceptions).
— Notch. The notch is also at the top of the display; however, unlike the “drop” described above, such a cutout is quite large — it usually houses not only the camera, but also the ear speaker, as well as proximity and light sensors. The fashion for this design was set by the iPhone X released in 2017, so devices with a notch are sometimes called “iPhone clones”. However, this is not entirely correct — most of them are completely independent devices, similar to the iPhone X only with a cutout at the top of the screen.
— Retractable. A camera that
...is completely hidden inside the phone and is pulled out of it only for the duration of use. In modern devices, such a camera is usually built into a small movable module, which, if necessary, “pops up” from the top end of the device. This design allows you to allocate maximum space for the screen on the front panel and significantly reduce the thickness of the top bezel; at the same time, the retractable module can be large enough, which allows you to install an advanced camera in it. The disadvantages of this option are the complexity of the design and the relatively low reliability (due to additional moving parts).
— In the display (cutout). The camera is located on a round cutout at the top of the display. Such cameras differ from the teardrop cameras described above in that the cutout does not come into contact with the edges of the screen. This design also allows you to significantly reduce the thickness of the top bezel and allocate maximum space for the display.
— Under the display (hidden). The most advanced of modern front camera form factors: the module is completely hidden under the display. Thanks to this, the lens on the front panel is almost invisible (except that the screen area under which it is located can slightly stand out from the rest of the image). Such a design is very expensive to implement, and therefore is found mainly among flagship models.DxOMark test (battery)
Mobile phone battery testing by the independent organization DxOMark allows you to get an informed assessment of the device in terms of the quality of the battery used and its performance. The tests take into account the dynamics of charging, energy efficiency, performance in various scenarios for using a smartphone (the load is simulated in games, during video streaming, voice calls, etc.). The final rating is formed according to the results of three parameters: battery life, charging diagram and efficiency of consumption of accumulated energy reserves. After passing the test, the phone is given points for the quality of the battery.
