iOS 5 Battery Life Issues

Many users who have upgraded to iOS 5 have noticed decreased battery life, the problem seems to effect iPhone and iPad users the worst, but some iPod touch users have noticed battery reductions as well. Even without heavy usage and when a device is in standby mode, the battery seem to drain much quicker than usual, suggesting something running in the background is causing the battery to drain all the time. Nobody has found the exact problem yet, but we’ve compiled a variety of tips and suggestions that help the battery life issue quite a bit with any iOS 5 device. Try them out and let us know how it goes for you.

Nuclear Option: Backup & Restore
The nuclear approach is a full restore of your iPhone or iPad, as there are some indications that completely restoring the iOS device can recover battery life quite a bit. If you go this route, be sure to backup your device first, and you can either download iOS 5 IPSW to restore from manually or try the standard iTunes Restore method. Either way you’ll need to then manually restore from the backup you made beforehand after iOS 5 has been re-installed.

I had the most success with disabling bluetooth and resetting network settings and then selectively disabling notifications for things I don’t need, but your mileage may vary. Interestingly enough, the battery issues weren’t present in iOS 5 betas, suggesting that a minor software change caused the battery life to worsen in the final release of iOS 5. Until an official update and fix comes from Apple (iOS 5.0.1?), try these fixes to stop the battery draining, and let us know what works and what doesn’t for you.
