Today Apple released its first update to iOS 5, earlier than was generally expected. Along with the usual bug fixes, this update brings aid to the dwindling battery life experienced by many owners of the iPhone 4S.
Users of the beta have reported that the improvements have been notable and they can generally make it through the day no problem. If you weren't lucky enough to test it out early, go and run Software Update on your iPhone and get it right now. It took a few minutes for our phones to realise an update was available so be patient and don't worry — it's there. Check out the Gizmodo post below for a more in-depth overview of what's changed.
