We’ll discuss a handful of free tools here, but many other benchmarking tools are available, too. The same approach is appropriate for Android-based devices.Ī number of benchmark tools are available online and in the Google Play market for testing device performance. Instead, we run a host of different tests to gauge how well various individual components work, then we weigh the results, and finally we reach a judgment about overall performance. When benchmarking a full-fledged desktop PC, we don’t declare that system faster or slower than another after running a single test that stresses a particular component. In evaluating the performance of an Android-based smartphone or tablet (or any other modern smartphone or tablet), it’s best to think of the device as a tiny PC. A handful of the tests that we’ll be covering here are cross-platform or run within a Web browser, meaning that they’ll work on iOS or Windows Phones-based devices–or even on desktops and notebooks–as well. Since Android’s ecosystem is far more diverse than its mobile OS rivals’, we’ll focus on testing an Android-based device here. As is true with desktop and laptop PCs, establishing the relative performance of mobile devices requires testing. Because of these hidden variables, a vendor’s list of specs doesn’t reveal the whole story. In addition, the two devices’ SoCs may be outfitted with different GPUs, different amounts of memory, and different versions of the mobile OS. A device produced just a few months ago may have the same numbers of processor cores and be clocked at the same frequency as a brand new device, but its underlying architecture may be far less efficient. The storage test will run for one scan of the available storage or for a maximum of about 1.5 minutes.The standard SoC (system on a chip) powering one of today’s mobile devices, however, is advancing at a rapid pace. not a MicroSD card) and this has more available space, then this will be used instead.Īn incrementing test data pattern is used. If the storage is split with a separate “primary shared storage” that is not removable (i.e. By default, the Internal storage will be tested (here internal refers to the internal storage available to applications). The storage test will write, read and verify available storage. The memory test will run for about 0.5 minutes. Varying test patterns are used to try and uncover different types of memory problems. The memory test will write, read and verify memory available to andTest. This can be impacted by factors such as the immediate previous usage, the ambient temperature, the case, holding the device and of course the device itself.Įach CPU test will run for about 1 minute. In this case, you will notice that the increase in the number of operations will reduce and the temperature will start to drop. 100C) and then throttle the CPU frequency to a lower value to reduce power and hence reduce the temperature. It is interesting to note that some phones very quickly (e.g. 8 CPU tests will run simultaneously on an 8 core CPU). A test is run simultaneously for each CPU core (e.g. The CPU test includes integer and floating-point tests. Often high battery use is due to the display (high brightness), poor cellular signal, an app using processing power or a battery that has had a lot of charge cycles (or damaged). If battery discharge is high (NOK), it is worth checking Android Settings –> Battery, to check what is using your battery. The battery discharge during the test will be checked and compared against predetermined percentage drops and if greater than these, the battery will be deemed NOK. To test the battery discharge this test should not be skipped, should be started with greater than 30% battery, should be run on battery power (not charging) and should be run while in a normal battery mode (not a battery saver mode). The temperature sensor shown is the temperature sensor with the maximum temperature. Battery and temperature information is displayed during the test (where available). The next screen starts some automated stress testing of the CPU, memory, storage, and battery.
