Okay thanks! New iOSes traditionally cause a hit on the battery, and smartphones don't excel in battery life as it is... I guess I'll wait a month or so after it is released to see how it does for those who upgraded iPhone 5's. Really not much in iOS 7 that makes me want to upgrade anyway. I'll probably upgrade my iPad 3 though once it is released since I keep it plugged in most of the time anyway. It will make a good test device to see if I want to upgrade the iPhone 5 later on.
