My battery life has been pretty poor to this point, so I have been going from full charge to completely empty. I was doing that today when my phone shut off because it was out of battery. I then went and plugged it in for about four minutes, then realized I needed something so I unplugged and turned it back on, and now am showing 43% battery! I figured it was a glitch with the stock battery display, so downloaded the BatteryLife widget, which confirms I have 43%... Does this mean I need to complain to AT&T to get a new battery, or a new phone? Update: I rebooted the phone again and was at critically low battery life. I reseated the battery and rebooted again, and now I'm at 5%. Weird.
