Apple’s iOS 5 Update: No Battery Drain Fix?

Some iPhone 4S users are still complaining about rapid battery drain following Apple's iOS 5.0.1 system update that began rolling out to users Thursday. IOS 5.0.1 was supposed to fix several bugs that caused some iPhone 4S and older iPhone devices to rapidly discharge their batteries. The update also brings more multitouch gestures to the original iPad, several bug fixes for iCloud, and improved Siri voice recognition capability for Australian accents.
