The good news is that an update is available that is said to fix the battery issue on the iPhone 4S. In addition, this is the first update available "over the air." No need to connect your iOS device to your computer. You can download it via Wi-Fi, though apparently not 3G or Edge. The not so good news is that according to PCWorld, some iPhone 4S users are still complaining about rapid battery drain.
