Apple recently launched the latest version of their mobile OS, iOS 5.1, and according to a number of reports, the update has brought significant improvements in battery performance on a couple of iOS devices.
The improvement seem to be more noticeable on the iPhone 4S, iPhone 4, and the iPad and iPad 2 with 3G connections, with users of WiFi only models also noticing slight improvements.
