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 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%.
Geekbench
The result shown by the device when passing the performance test (benchmark) Geekbench.
Geekbench is a specialized benchmark designed for CPUs. Since version 4.0, the test has also been applied to graphics accelerators; towards the end of 2019, the benchmark was released under the number "5". The characteristics of portable gadgets usually provide data specifically for the CPU. During testing, Geekbench simulates the workloads that occur when performing real-world tasks, and takes into account both the capabilities of a single core and the efficiency of multiple cores running simultaneously. Thanks to this, the final results characterize well the capabilities of the processor in everyday use. In addition, the test is cross-platform and allows you to compare the CPUs of different devices (smartphones, tablets, laptops, PCs). The help information only lists the multi-core test values for CPU.
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.
