Yesterday was the first day it really irritated me. I took the phone off the charge around 8am and by 1pm it was dead! Texting and moderate web browsing, no phone calls, brightness down to 50%, wifi and bluetooth off. Do you think this is a defective battery? I have to carry around a usb cord everywhere I go it dies so much. I am running ATK, but all the primary apps/programs that run are always left on, I have it only killing apps that I open. So frustrated. I love this phone, but the battery is killing me. It's like having a supermodel girlfriend with herpes.
