TechSpot has done some testing to see what video formats and what video applications give the best battery life on Windows 8 based tablets. The results surprised me. Testing various formats, resolutions with battery life and CPU usage can take a long time. Hope he had some good movies and a lot of popcorn!
Over the course of the last two weeks, I’ve been digging deep into what the optimal playback setup is for lengthening battery life. Throughout more than 145 hours of testing, I’ve looked at a range of Windows video players, including the stock Windows 8 app, Windows Media Player, VLC and MPC-HC, plus many encoding formats such as H.264, Xvid, and the all-new HEVC format.
