I noticed a very strange thing this weekend when I spent the entire weekend at an outdoor music festival with 60,000+ people (Austin City Limits). Usually at the end of the day of normal use, my battery will be down to about 80% full. I can usually squeeze a couple/few days before I need to recharge. But at ACL, my phone was noticeably hot the entire day and even by the time 10:00 rolled around was almost completely drained. And I hardly used it at all. Does anyone know what could have caused premature battery draining in this situation? My girlfriends RAZR didn't behave differently at all.
