Reading some of you guys posts I think I may need a new battery. I've had my phone for about 3 weeks and only get 6 maybe 7 hours usage before I have to recharge. I do admit that is with heavy usage especially since I work nights a lot so my screen is constantly on. I believe I conditioned my battery right. 3 cycles letting it full discharge although I'm not sure if I plug it in when the battery indicator is red or are you supposed to let the phone turn off itself first? Anyway my main culprit is my display it always takes like 80% of my batteries life even though it is set to auto with the slider below 50 and power save mode is on. So am I doing something wrong or do I need a new battery?
