My phone has terrible battery life... And yes wifi, gps, 4g, etc are all off. The screen isn't too bright. When I play games it goes from 40% to almost dead in about 30mins. I also have a 1750 mAh battery so it should be better than average. So is there a way to test it? I went to a Sprint repair store and they couldn't test it because its a 3rd party battery :/ Thanks!
