iphone 4s battery life
I fully charged (100%) my brand new iphone 4s (ATT) at night and went to bed and woke up with 87% battery life remaining. I closed all background apps, reduced brightness to auto, minimum, and turned off location services for many apps. I also turned off wifi, because I have a good cell signal at home and want to stick it to ATT because I have unlimited data plan. Other than setting my alarm for wakeup at 6am, what is draining the battery so much during a 7 hour sleep cycle?
iPhone 4S, iOS 5
