How to troubleshoot iPhone5′s battery life drain issues
Many users are reporting problems with battery life on iPhone5. Whilst we’re waiting for Apple to acknowledge this fact and hopefully provide a firm solution, here are a few tips for how you may be able to improve your iPhone5′s battery life:
Tap SETTINGS > GENERAL > RESET > RESET ALL SETTINGS
This will reset general settings on your iPhone such as your saved wifi networks, passcode lock, homescreen image etc.
It won’t delete any of your data though (eg: your apps, music or photos).
I tried this on an iPhone5 earlier today and have noticed an improvement in battery life as a result, so this is the one I’d recommend you start with.
2) Full Battery Drain & Recharge
Try letting your iPhone5 battery drain fully to 0% so the phone switches itself off. Then connect it so it starts recharging and don’t disconnect until the battery is back up to 100% again.
Tap SETTINGS > ICLOUD and swipe the ‘Safari’ option to OFF.
This will stop Safari from syncing your open tabs from all of your supported devices that have iCloud Safari preferences enabled.
(To use this feature, your Mac must have OS X Mountain Lion and Safari 6, and your iPhone, iPad, or iPod touch must be using iOS 6).
4) Full Restore To Factory Defaults
Finally, if all else fails, some users have reported that when restoring an iPhone5 to factory defaults and not backing up from a previous iPhone has shown improvements in battery life. This involves plugging your iPhone5 into iTunes and clicking the ‘Restore’ button.
It’s strongly advised that you backup your phone before doing this. However this also means your phone will be wiped of all data and you’ll have to start from scratch installing all your apps, syncing your music, etc. But if you’re at your wits end and have explored every other option it could be worth a try.
