[Updated with info from AOL on the "meeting managment" bug] Some iPhone owners are complaining about battery life and/or overheating after upgrading to
iOS 6.1, according to
multiple threads on Apple's support forums. The exact cause of the problems is unknown, but one owner notes that their phone appears to have been running something in the background, and that a factory reset fixed the situation. Some
reports specifically suggest that the problem is related to Mail's handling of Exchange.
