Apple released the iOS 5.0.1 firmware yesterday to fix numerous issues with battery life that users were facing while running the iOS 5.0 firmware. Although Apple has managed to fix a lot of errors that were associated with the official iOS 5.0 firmware, there are still some users reporting the same battery life problems after updating to the latest iOS 5.0.1 firmware. To make matters worse, some people have even noted that they are experiencing worse battery life after updating.
According to AllThingsD, Apple is indeed aware there are still issues with the iOS 5.0.1 firmware, and they are further looking into fixing the remaining battery life issues. Apple commented:
The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices. We continue to investigate a few remaining issues.
If the above statement is indeed true, we are sure to see iOS 5.0.2 released within the next coming weeks
