secret process causing battery drain anyone notice suspicious battery drain? i've noticed on one day I can play mp3's for 30 min, surf the web, do messaging, make a few calls, and my battery lives on for the full day (16 hours) without an issue. on two other occasions i BARELY used the phone, maybe 5min of total talk + internet time, and the battery was dead in 10 hours. i'm thinking some rogue process was running in the background. unfortunately there isn't a great way to see whats running and switch to them and kill them off. anyone have this and what do you do?
