Despite promises of fixing the battery related problems of iPhone 4S users, iOS 5.0.1 has failed to do the expected.
People who were unhappy to see the batteries of their iPhone 4S and iPad getting drained so quickly have a reason to smile.
Apple has released iOS 5.0.1 that fixes these problems. Apple claims that this update fixes the bugs that plague the battery life and document syncing. It also re-enables the app switching gestures that developers could previously access on iPad.
