I've had my Droid since it came out and have had this problem since I got the phone... It spontaneously begins to update itself (with the little swirly progress arrow in the menu bar at the top), gets extremely hot to the touch, and usually doesn't stop till it kills the battery - which often only takes a couple of hours, even if the phone was fully charged at the beginning. I've tried using TaskKiller to wipe everything out and stop the process, but nothing works - it keeps going till it decides to stop or until it dies. Rebooting the phone also doesn't work - when I turn it back on it picks up where it left off. It's extremely frustrating because not only does the Droid die all the time, it charges very slowly while plugged in if it decides to self-update. This usually happens once or twice a day. Any ideas? Thanks so much for any help you might be able to provide!
