I have an Evo 3D and last night, before going to bed, I plugged it in till fully charged, listened to a couple songs on Last.fm, then on the standard Music app (maybe 10-15 minutes worth) and went to sleep. As always, I opened the task manager and killed all the applications (refreshing them since a few tend to pop back up a couple times before indefinitely going away).
I woke up today about six hours later to check the time and found that my phone was turned off. After I turned it back on it told me it had 1% battery life left.
Needless to say, I'm flabbergasted by such an absurdity. My phone's battery hasn't exactly been great, but it's at least held a charge overnight (until now). Since I killed/closed all the running applications before falling asleep, I don't know how it would have something out of the ordinary running.
Anyone have a solution to this?
