Apple double-checking iOS 5 post-patch battery bug
Apple in a statement on Friday said it was looking into persistent battery issues for some users following the iOS 5.0.1 update. It stressed that the fix worked for "many of the battery issues" encountered with the original release, but added that it was working on more. No immediate estimates were given for if or when a follow-up fix might arrive.
"We continue to investigate a few remaining issues," Apple said.
Most of the customers still facing battery issues are iPhone 4S owners. Apple hasn't narrowed down exact causes, although some have speculated that the cause is excessive use of location data, corrupted contacts that repeatedly try to sync, or a very active infrared proximity sensor.
The issue isn't consistent, and some with the iPhone 4S and older devices haven't noticed any significant difference.
