How we test
TechRadar aims to produce the most helpful phone reviews on the web, so you're able to make a more informed buying decision.
Part of this testing process includes benchmarking. It's a good way of measuring the overall performance of a product's internal hardware components.
We use Antutu System Benchmark to test tablets. It's a comprehensive Android benchmarking app and produces consistent results.
Antutu measures an Android device's CPU performance, 2D and 3D graphics performance, memory speed and internal and external storage read/write speeds. It combines the results for each test and gives the device a final score.
We test each device three times and take an average.
