Aight so I was just in class and i had 70% battery. So I go to check my facebook, battery is still at 70%, refresh my notifications, still 70%, then go to the home screen and kill most of my apps, save handcent and taskiller, and lock the phone. About 15 minutes later, I get out of class and the red light is blinking and my battery is at 5%! Wtf, mate? Less than 20 minutes later, I lose over 60% of my battery? Also, I just plugged it in and in less than 5 minutes it's back up to 60%. Any explanations, is my battery/whatever reads the battery life going funny? Or is this likely some freak happening?
