RAM
The parameter determines the overall performance of the smartphone: the more RAM, the faster the device works and the better it copes with an abundance of tasks and / or resource-intensive applications (ceteris paribus). This is even more true in light of the fact that large amounts of "RAM" are usually combined with powerful advanced processors. However, only devices with identical operating systems can be directly compared with each other, and in the case of Android, with the same versions and editions of this OS (for more on all this, see "Operating system"). This is due to the fact that different operating systems and even different versions of the same OS can differ markedly in terms of RAM requirements. For example, iOS, thanks to good optimization for specific devices, is able to work efficiently with
3 GB of RAM. For modern versions of Android in the regular edition (not Go Edition), the mentioned 3 GB is actually the required minimum. Under such an OS, it is better to have at least
4 GB or
6 GB of RAM. In high-end devices with powerful electronic "stuffing" you can also find more impressive numbers -
8 GB or even
12 GB or more.
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.
Battery capacity
The capacity of the battery that the mobile phone is equipped with.
Theoretically, the high capacity of the battery allows the device to work longer on one charge. However, actual battery life time will also depend on the power consumption of the gadget — and it is determined by the hardware specs, the operating system, special solutions provided in the design, etc. So in fact, phones with capacious batteries in general have
"long battery life”, however, the actual battery life can differ markedly even for two models with similar specifisations. Therefore, for an accurate assessment, it is better to focus not on the battery capacity, but on the operating time in different modes directly claimed by the manufacturer (see below).
