So you guys have battery problems? Cool. I never did, until....I installed a screen protector!! I realized after a few days that my battery life was drastically shorter. I also realized that I had inadvertently covered one of the sensors on the front of the screen by the speaker with it, because the whole was not lined up perfectly. My guess is that it is possibly misreading the amount of light entering the screen and my "auto" brightness is pulling a lot of battery. I took the screen protector off, put on a fresh one - lined up properly - and POOF! Battery life was doing great again. Just thought I would share.
