Today we are releasing a major update for our PCMark for Android benchmarking app. The update adds two new benchmark tests based on real-world activities and an exciting new way to compare the performance of devices across Android OS version updates. The best way to benchmark smartphones and tablets is to look at the performance of the device as a whole. PCMark for Android uses tests based on everyday activities. By using real applications and native APIs, scores from PCMark for Android better reflect real-world performance and battery life. Alex Voica, Senior Marketing Specialist at Imagination Technologies, says, "PCMark is actually a solid example of mobile benchmarking done right."
