ios 11 update phone freezing

Hi, I updated to ios 11 on my 64GB iPhone 6s without any issues. But since doing so my phone has stopped working 3 times. The problem is that the phone freezes and I can't press any apps or open app switcher, it's just dead. I have to do a force restart to get back up running again.

iPhone 6s, iOS 11

What troubleshooting steps have you tried so far?


One that frequently helps after an update is to kill all processes, then restart the phone. This is non-destructive; it will eliminate the possibility that there is a "stuck" app.

  • Double-press the HOME button to display the quick-launch screen
  • Swipe up on each screen image to kill each app
  • When there is nothing left except the Home screen image, double-press the home button
  • Hold the SLEEP button until "Slide to power off" appears, and do so
  • Wait about 1 minute, then restart the phone by holding the SLEEP button until an Apple logo appears.

Same issue. iPhone SE less than a year old. Not acceptable to have to do a factory reset. I have to hard reset 3-4 times a day. It seems to *really* dislike following links that open other apps - for example clicking someones profile link in instagram.


You have several options:

  • Troubleshoot the problem, which may or may not require a factory reset.
  • Live with it
  • Throw the phone away.

That's about the limit of your choices. If it is truly not acceptable to have to troubleshoot it, you might as well throw it away. There are no other solutions.

Some IPhone 6S Plus models have Samsung chips as well. You may want to use the Geekbench app in order to know the exact chip model you have in your iPhone. If you have N66AP then it’s samsung as well.


For your reference:


iPhone 6s – Model N71AP – Samsung A9

  • iPhone 6s – Model N71mAP – TSMC A9
  • iPhone 6s Plus – Model N66AP – Samsung A9
  • iPhone 6s Plus – Model N66mAP – TSMC A9

I am using iPhone SE 64GB with latest iOS 11.0.3. I am not seeing a crash or freeze anymore and the overall system is stable and running smooth.


Here is what I did and I strongly feel that the freezing is related to location services: [Before making following adjustments, my iPhone used to crash or freeze many times]


  1. Make sure under Settings -> Privacy -> Location Services, choose "While Using" or "Never" depending on your preference for the apps. Try to set "Never" for apps which you need location service. Avoid "Always"!
  2. Under Settings -> Privacy -> Location Services -> System Services, turn off location service for all system services [under PRODUCT IMPROVEMENT section too].
    • I kept following turned on as I need them:
      • Compass Calibration - For Google Maps, to get the direction arrow [blue one]
      • Emergency SOS
      • Find My iPhone
    • For every other system services, I turned off location service.
  3. Under Settings -> Privacy -> Location Services -> System Services, turn on "Status Bar Icon" so that you will see if any app/service is trying to access location and find out the culprit when your iPhone is freezing or crashing.
  4. Delete apps which you don't need!
  5. Under Settings -> General -> Background App Refresh, turn it off.
  6. Under Settings -> General -> Handoff, turn it off.
  7. Under Settings -> General -> Date & Time, turn off, "Set Automatically" if you do not travel often.
  8. Try to turn off other services or settings, which you do not.

My iPhone 6S 128gb froze for the first time this morning. I have taken the IOS 11 updates over the last 4 weeks or so, which slowed it down a lot over IOS 10 (which I would have reverted to if it had not been withdrawn).

For what it is worth, while frozen it

  • would still show the control screen
  • play music - 4 pieces cycling for which I could control the volume and jump forward or back
  • the Safari button was greyed out
  • nothing else responded

A forced restart appears to have returned it to normal function for now. Let's see.

Hi Lawrence,


I tried this and it settled down for a day. It then froze again. I have since upgraded to an iPhone 7 plus (didn't fancy the 8 for some reason) and it has again frozen. I keep my phone and message apps in a folder. I had gotten a missed call, I opened the folder and pressed the phone app. The app would not open, I could close the folder then my phone was again frozen. There is definately a bug in the ios 11 that needs addressing.

If it was definitely a bug in iOS 11 then I would have it also. And about 100 million other users. And I keep my phone and several other apps in a folder also. If you just wait for Apple to fix this non-bug that is actually something wrong on your phone you will grow old first.


Restore the phone using iTunes and set it up as New. Don't add any apps, don't set up any mail accounts, don't even log in to iCloud. See if it works. Most likely it will, meaning it is not a bug in iOS, because if it was the problem would still be there. Then start adding stuff back. First, log in to iCloud. If that is OK then add your email, and apps, a few at a time.

Not entirely true Lawrence. There have been instances over the years where Apple have issued software updates to fix various issues such as battery drain etc. I haven't been affected by these issues when lots of others have which would suggest that not every phone gets affected by software bugs.

It is also a huge waste of my time having to reset my phone and lose lots of data at the same time. I pay premium money for my apple products so I don't have to do these sorts of things.
