GPU Acceleration and Battery Life During Video Playback on Windows 8.1


This is what I have been doing for the past few days: draining the battery of my new Dell Venue Pro 11, a Windows 8.1 tablet (the real deal, not RT). I wanted to find out how good Windows has become at battery-efficient video playback and how that is affected by GPU acceleration.

Measuring Video Playback Battery Life

Have you ever asked yourself how battery life during video playback is measured? Apparently hardware testers configure a video to play in a loop and ping the device from another computer. When the battery dies, the pings are not answered any more and, voilà, you have got your result. In another variant a batch file is on the device to be tested. The batch file regularly writes the current time to some file.
