iPhone 4 battery draining fast all of a sudden - Is there an app for that?
I've had my iPhone 4 since July and have actually been pretty happy with the battery life. However, over the last 3-4 days, the battery has all of a sudden started draining very fast. In the past, I've been able to go a whole day without charging. Now I can barely make it to mid-afternoon with the same usage pattern before I'm down below 10%.
I suspect there's some app that's chewing the battery up but I can't seem to figure it out. I've killed all the background tasks and deleted anything I've installed in the last week.
Does anyone know of a good app to track battery usage to help me pinpoint the problem?
