iPhone 6 very slow with IOS 11 update

After receiving IOS 11.01.1 on my MGCT2LL/A1522 (iPhone 6), my phone is super slow. Apps hang, then close (like the Starbucks app), my purchased music would just stop in the middle of a song, then I had to close the app and re-open.

In general, everything is very slow to respond, and I have rebooted twice.


Any suggestions

Many apps unresponsive. Phone also running extremely warm and battery draining very quickly. Turning off background app refresh makes no difference whatsoever. Hard reset has no effect. I have 78GB free.

I too was seeing in the battery usage info that my 'No Mobile Coverage' was the highest battery drain at 53% over a few days. I have no mobile coverage at home, so use the WiFi calling option, However, as the phone boosts power to try and get a cellular signal (which it won't if you are in a no coverage area of course) - it can cause a battery drain quite rapidly.


In these situations, at home, you have to put it into Airplane mode, which turns off the cellular and then re-enable WiFi so stop this happening. Don't for get to switch off airplane mode when you go out again!

Not only is mine slower but now needs to be placed on a hot radiator for 10 minutes to get it to switch on in the morning. This is absurd.

Either you're living in an unheated location in a cold environment or there's something seriously wrong with your phone. Putting it under a heater will only make things worse. Make an appointment at the Genius Bar at your local Apple Store and have them evaluate it.

You go to bed and turn off your phone at about 43% battery remaining, leaving it on the table. The heating is off overnight and so room temp drops to between 12 and 14 'C in winter. You wake up and go to switch your phone on, but it shows the charge symbol. You then keep the phone in your pocket for 20 minutes or place on a warm surface for 10 minutes (radiator), it then not only switches on but shows 41% battery remaining. This never happened until iOS 10 installed!!

That's not correct. If you are in a no coverage area the phone will still try to connect periodically (it has no way of knowing it's a no coverage area until it checks), and it will do so using its maximum output (600 mw). It will thus put a significant load on the battery. If you are in an area that you know has no coverage but you have Wi-Fi put the phone into Airplane mode, then turn on Wi-Fi.

Good news. Tim Cook says that a future version of iOS will let users control this feature and turn it off if they don't want it.

We will tell someone we're reducing your performance by some amount in order to not have an unexpected restart. And if you don't want it, you can turn it off.

It seems that they will roll this out in a developer beta next month, so it will take some time to get to users. But it's very good news, and what they should have done from the start.

A big part of the problem is the training Apple gives their tech support people.


I contacted Apple tech support about six weeks ago to discuss the slowdown on my iPhone 6. At that point, the connection to the battery was being discussed widely on websites and in newspapers. But the tech support reps I spoke to had no clue about it. They wanted me to do a factory reset on my iPhone and then reinstall all my apps one at a time. That's right, they said I shouldn't restore from a backup because that could perpetuate the slowdown.


The "solution" they offered would have been a lot of work for me and it wouldn't have solved the problem. Meanwhile, anyone paying attention to Apple news knew what the problem was.


Why doesn't Apple train their AppleCare representatives on the technical causes of these common problems? Let's hope they do much better when this next update comes out. It's not rocket science.

I feel the same way... also, the new iphones don't have an output for headphones and I really need one that has an output. :/

This is such a same. I never thought I'de be thinking of moving to Android. I'm going to wait and suffer a bit to see how things will turn out before I buy an Android. But it's so frustrating having to charge constantly. It's affecting my work too!
