One redditor talked about a strange problem where the iPhone – after upgrading to iOS 7 – turned off abruptly (and suddenly). Not only this, but the iPhone could be switched back on only after a few minutes of waiting.
This problem doesn't seem to be very common or widespread – I've only seen remote cases of these being discussed on the web. There's a couple of things you can try to fix this issue but as far as I've seen, Apple hasn't acknowledged this. We're on our own.
In one instance of this, the issue seems to be with a battery false-caliberation. So what happens after an iOS 7 upgrade is that the battery shows 10% but it's actually at 1%. The iPhone turns off even when, apparently, there is enough battery left to last a few minutes or an hour (depending on the usage).
In another case, the sudden turning off did not have anything to do with battery. It just happened randomly – a few times a day – and it took some time to turn on the iPhone back on.
Judging from the way this problem is shaping up, it's hard to fix the issue to one particular bug. The problem could be caused by a lot of factors:
- Bad battery caliberation
- One or two buggy apps that are quietly doing the deed
- Problem with iOS 7 installation/settings
How to Solve Frequent iPhone Turning Off Issue After iOS 7 Upgrade?
This is where it gets a little tedious.
The first thing you can try is this:
- Let your iPhone drain out completely (use it till it switches off on its own). Don't charge it at all.
- Once it loses all the charge, connect it to the charger and let it be. Don't use till the iPhone gets charged to 100%. You might want to do this overnight.
Does this fix your problem?
You can try removing certain apps that have not yet been updated for iOS 7. If you have a limited number of apps, you might want to test and tweak the app usage to see if that has an effect on the problem. However, a large number apps means you can't do that without losing your mind.
The other thing you can try is a simple restore.
- Have your data backed-up to iCloud
- Restore as a new device (or through Recovery Mode)
To put the iPhone in recovery mode, press and hold Power+Home button till the screen goes blank. Connect the iPhone to your PC and iTunes will recognize a device in recovery mode. Restore firmware to install iOS 7 as a fresh copy.
- Then, after the restoration, get your data back from iCloud.
