iPhone 4S battery bug confirmed by Apple

Apple has confirmed that the unusually low battery life seen by some iPhone 4S owners is down to a bug in iOS 5.

Some iPhone 4S owners found that battery life was very low and a number of workarounds circulated that improved matters for some users including disabling the time zone feature.

Apple have now confirmed that a bug in iOS 5 is to blame but characteristically refused to be drawn on what users might do as a workaround.
