iPhone 6 keeps restarting after new iOS 11 update

They have not fixed the problem. I can’t even type a message longer than this without my phone rebooting. My clock was frayed out but isn’t any longer. My phone updated automatically even though I have declined the upgrade several times.

Jackie, thank you very much. It actually did something by itself and allowed it to finish the update. This "patient" has been stable for a while now. LOL I pray it stays that way because today is shopping and errands day, so being out there without a phone is quite an inconvenience. I am an older person not as tech oriented, so I am so happy (for now) that it fixed itself. Thank you for the prompt response. Have a great day!

Started last night (Dec 2 at around 1:00AM, My phone keep rebooting. It seems that upgrading to 11.2 solves the problem, but how can you upgrade if the phone keep rebooting all the time??? I can't even connect my Iphone to my computer to backup data. Please help!

Not in my case, the only stable version is iOS 10.x. iOS 11.x has killed the phone. I have all notifications turned off, time rolled back, network data off, everything switched off basically. There are many potential fixes, but the one thing that stands true is that the iPhone 6 was not an ideal candidate for iOS 11.

With that said ... I see no representative of Apple making apologies or offering anything to those who now own a brick.

For some reason I can't mark "Helpful" on comment above, I have the same problem and my phone is only usable if plugged in at this point. iOS 6 should not have been upgradeable to 11. Apple needs to allow a downgrade for this phone rather than forcing people to buy a new device. If a fix is not presented in the next couple of weeks, I'm going to Android (that will happen regardless after this mess but I prefer not to spend money I don't have to replace what was before a perfectly good device).

I have had no issue with my iPhone 6 apart from yesterday’s date bug which was fixed by updating to11.2. Yes it took a while to update with the screen locking but I left it to its own devices and it works a charm now.

Ah well at least you looked at your Clock app to ascertain this wasn’t the problem.

I’m assuming it was a pain to update to the most recent ios11.2 yesterday to see if it fixed it then update all your apps only to have to reinstall from your earlier iOS back up.

I got told about an app called BSSM it tells you cool info about your phone chip etc Actually probably from this thread.

Good luck with your issue hope the phone shop can sort it out.

Thanks. If I I stall as a new phone I can just about get to the end before it restarts .... there is no way on earth I can get to the end of an icloud restore. Even so, whilst the new iOS loads there are 3 restarts. Now I have a clean 11.2 install which restarts every 2 minutes! Sadly, the only answer hear is to allow iPhone 6 users to downgrade to iOS 10.x

I can see a lot more of this coming to the fore before much longer!

I've just installed 11.2 a few hours ago and I'm testing. I'm having better luck than dybmowst but it did restart twice when it hit about 65%. I was being super intensive with it (I was listening to downloaded music with headphones and it was in my pocket, screen dark and most notifications off) ; ) The camera was snappier so it seems to be quicker, but I have to test it at battery level below 60% to really see, that is when it usually goes into the restart loop.

I spent several hours in the last 24 hours or so helping many people who posted roughly 20 different questions about the same problem in this site and others. I could have just told everyone to "you need to read the whole thread" but I elected to answer their questions instead.

I upgraded my iPhone 6s plus to IOS 11.1.2 yesterday evening and my phone has been restarting randomly all day at intervals of about 2 minutes! I have done hard reset. I have disabled third party notifications under settings but all these dod not fix the problem. I cannot type a complete sentence on the iPhone and making or receiving calls is with many disruptions. I bought this phone (new) in September 2016 from Apple store and it has been working fine before the IOS update. I will appreciate any suggestion to fix this problem.

I am pleased that it works for you, sadly many of us are still suffering restarts even after a clean 11.2 install.

I wonder about having replacement parts in iPhones causing problems with iOS 11.x?

If the other chaps are following this, how many suffering continual reboots have one or more of the following ...

Aftermarket screen, aftermarket battery ... or a faulty home button through using a replacement part.

There has to be a commonality somewhere!

Hey Levinac,

I hope you managed to get your iPhone working again.

I have been sitting on the side-lines for a month, waiting for Apple to contact me ... Which they did, and then collected a couple of hundred MB's of log files from my iPhone. But, as an update for the many who followed this conversation, I will just say that Apple disappeared into the ether and have never contacted me again. I emailed the support person for an update, but got fobbed off with "I am typically not informed of any updates once the diagnostics are submitted. If at any time you would like to see what service options are available for your device, you can call 1-800MyApple for this information."

This doesn't go anywhere in as far as delivering satisfactory customer service, and certainly has not brought my iPhone back to life! All of the tricks, tips & hints found in this conversation have not worked, and whilst Apple showed a spark of interest, it has dwindled to nothing.
I am glad I have my trusty Android at my side .... not a glimmer of trouble!

Start a new thread for your answer so that the people following this do not get confused about the different answers.

I have the same problem, phone is unusable. Apple keeps censoring my post.
