I started a new thread since, although there are a ton of "get better battery life" threads, this doesnt really fit. And which one should i put it in? Yesterday, I unplugged my phone from the wall at 3pm. I performed many tasks on it through the day, never any prolonged activity. A few phone calls, occassional Twitter checks, some email (gmail) checks, and maybe 45 minutes of sustained web browsing while I watched TV. The phone showed "49%" battery left. I went to bed at 4am (F'ed up sleep schedule), rebooted the phone to clear any background apps that might be running, made sure that wifi and gps were switched off, plugged the phone in and went to sleep. I woke up this morning at 8, left the phone where it was, and at 9am, the phone beeped. I though it might be an alarm that was set, but it was a beep notifying me that the battery was dead. It turns out, the plug had come out of the wall socket, so the phone wasnt getting any power. Fine... I'm an idiot...but what I dont get is how the phone lasted 13 hours making phone calls and browsing and app playing, etc., and only got down about 50%, then in 5 hours just sitting there, it drained the remaining battery. Something was happening. (I had no twitter, email, calls, or SMS over the night.) I just dont know if the battery meter is off, if BatteryLife app is off or whatever else the problem might be. It no big deal that it happened NOW, but bad battery life or night, I need to at least be able to trust the power information I'm given. Any ideas?
