Over the past couple days my battery has recently just been terrible. I go 3.5 hours, screen on for 22min an my battery is at 60%. I use to get around 14 hours out of my battery an now its not even close. I haven't changed anything recently, still running BB.4. Could my battery just be near its end an its just starting to deteriorate now? I know batteries get worse the more they are charged an lose their life. I've had my droid since release. Is this possible?
