iPhone 6 keeps restarting after new iOS 11 update

I am currently abroad on the other side of the world and i've recently updated my iPhone 6 iOS to the newest 11 and after I charged my phone to 100% in this location, my phone keeps restarting. This is the second time this has happened. The first time after I charged it to 100%, I unplugged and the problem began. I plugged it back in and it said 1% while charging but when unplugged showed its true battery percentage. I was able to run it down to 10% where it went to Low Battery Mode and it all seemed to go back to normal.


A few days later (today) I charged it to 100% again thinking this time it will be ok, but after an all day tour (pictures and uploading included) it was still 100% at the end of the day which I found odd. I shut down my phone (mistake) the normal way by holding the power button, and after I turned it back on, it immediately said 1% and the restarting began. Even when I charge my phone now it says 1% and after unplugging still says 1% whereas before it showed its true percentage. I don't think I'm able to run it down to Low Battery Mode like last time. I'm at a loss and the nearest apple store is 2 hrs away. What are my options?

Just in case it wasn't clear earlier here is the fix released today:


Update to iOS 11.2

Settings > General > Update

Official update from Apple:

If your iPhone, iPad, or iPod touch unexpectedly restarts - Apple Support


If you can't update:

December 2 "respring" Clock/Reminder restarting/overheating iPhone bug

If you still need help try updating your iOS device with iTunes on a Mac/PC by a USB/Lightning cable connection:

iTunes for Windows: Update the software on iPod, iPhone, or iPad

(This article is for Windows, but it's a similar procedure for Mac)

My phone did this because of some unfortunate app interactions. Try this: Restore from an iCloud backup (look online to find out how to do this) then stop the backup after you have access to your phone but before the apps all redownload - you can easily stop the downloading by pausing each individual app or by turning WiFi off and by making sure the apps store cannot be accessed by cellular data. Use your phone for a couple of hours like this to make sure it fixed the problem. Then slowly add apps a few at a time. Eventually you will have the problem again and you have found the guilty app. Do the whole thing again and delete that app rather than letting the backup download it. Good luck.

I faced same problem my cellphone started restart after every 3,4 minutes. I read out here commented by some one that change your cell date to November I did same Nd it worked then I updated my phone to iOS 11.2 nd changed date to current date Nd time now my phone is working good...

Please Apple never do this type of bug fixes which create problems for users.

It seems to me that there is little point in trying to bring this to the attention of Apple. I have had this problem before, I fixed it by downgrading to 10.3.3 with an ipsw file. Now I upgraded back to ios 11.0.3 some time later (expecting some fixes to have been made) and the iphone is now restarting again every 2 minutes. Because my iPhone is old and out of warranty, and has a replacement screen on it, Apple refuse to believe that their ios upgrade is faulty .. or the cause on an iPhone which keeps randomly rebooting. Even during the setup process this keeps happening.

I spent 2 hours on the phone to Apple tech support as a result of the problems .... They will take you through all the usual resetting the software and everything else they can read off the crib-card. But actually, and despite any kind of reset or reload of the ios the handset keeps rebooting every 2 minutes. IT DIDN'T MISS A HEART-BEAT WHEN RUNNING IOS 10.3.3!!!!

As I sit here typing this my iPhone has rebooted several times ... and I haven't even touched it! Apple are quite literally washing their hands of this problem, and anyone who has had an iPhone working well previously, and now finds themselves with a paperweight, have no recourse of action. They say drop it into a service centre, get charged £200 to fix it and you can have it back working .... Apple bust it with a bad ios upgrade, and want to charge you nearly as much as a new phone to fix a problem which they caused in the first place!!!


As you can see, I am very angry about this and I think that I will now be going back to Android as they are by far more reliable.


P.S. I am a pofessional in the digital telecoms world ... this is not my first rodeo with digital communications technology!!!

Hi if you have the date bug then the clock app is greyed out when you open it. So I strongly suggest updating to iOS 11.2 no need for a new phone !

Go to settings display and brightness and change the lock screen to a more suitable time.

If you didn’t upgrade to ios 11.2 I suggest you do because it fixed the problem for me and I was on 11.1 before. I’m just a human with an iPhone.

Hopefully it works.
