The phones we chose for the testing were the HTC Evo 3D, the HTC Sensation 4G, the HTC Thunderclap, the Motorola Droid Bionic, and the AT&T Samsung Galaxy S II. We reset each phone to factory settings, with Wi-Fi disabled and 4G happening. We typeset the phones to play a high-def picture connected a loop, with the screen at supreme brightness level, until the phone battery died.

Advanced Task Killer has a assortment of kill modes (Safe, Aggressive, and Crazy). We left it on the Safe place setting and had it stop apps every half hour; this setting kills apps that aren't unfold but quiet devour memory. The developer recommends the Innocuous setting, since the other 2 settings can cause some apps to become unstable.
