I made an appointment to go to the genius bar to talk to someone about my iPhone. it has a serious battery issue. i got it on launch day and the battery sucks. it drains 30% after just 30 minutes usage with safari. i'm on 40% right now and i only talked for about 3 hours total today. it drains soooo quickly. i have recorded alot of usages and battery readings. what do you think they are going to do? thanks!
