Apple yesterday released the iOS 5.0.1 software update which, among other fixes and features, included optimizations for battery life of devices running iOS 5. In particular, a number of users in the past weeks have reported shorter than normal battery life on the iPhone 4S, Apple’s latest iPhone model released on October 14th. Apple promised that the iOS 5.0.1 update would fix a software issue that had affected battery life on iOS 5, not just the iPhone 4S.

Yet after the release of iOS 5.0.1, which was distributed over-the-air to iOS 5 devices as well as through iTunes, several users on Apple’s Support Communities reported battery life issues similar to pre-iOS 5.0.1 scenarios, if not worse after the upgrade. In a statement issued to All Things D, Apple says they will continue to investigate issues with battery life:

The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices,” the company said in a statement. “We continue to investigate a few remaining issues.

As Apple keeps working on iOS 5 and improving the system’s battery management, a number of users suggest that disabling some of iOS’ Location Services and Notifications might improve battery life dramatically. Apple doesn’t specifically recommend any of the “tips and tricks” found online, though it does offer a Feedback page for all users willing to report back about their experience with iOS devices.
