My Galaxy S3 used to show, on the battery, under settings, the apps that were draining it (Facebook, Outlook, Twitter) and the percentage each was using. Now, it only shows screen (which is always at 90% or so) and other basic functions, like Cell Standby and Device Idle, which are around 4%. This happened after an update. It'd be nice to know what apps are draining my battery, which tends to drain quickly. Any ideas?
