iPhone 6 very slow with IOS 11 update

11.0.2 has done nothing to fix how slow everything is. My phone started not “waking up” after 11.0.2 update. I have to wait several seconds after pressing home button or lock button for it to wake up. Usually after about 6 or 7 tries.

Same here. I'm for the moment using my old iPhone 6 and it's super slow.

After upgrading from 11.0 to 11.0.1 the problems disappeared for one day. Now its back.

I tried force restart but it didn't solve it.

My iPhone 7 (which now is at service center) didn't have this issue in iOS 11.

Any idea?

I'm on an iPhone 6 as well having the same problems after this update too. It is also effecting the GPS with some apps. Navigon keeps saying it can't keep a GPS signal while Waze is complete fine. This is a very frustrating major update.

I have the same problem with waking up my phone, ever since (pretty sure) 11.0.2. This was not happening when I first upgraded to 11.0 or 11.0.1. My power button works to turn the screen off, but when I press the home button to wake it up, I'm staring at a black blank screen for several seconds until it will finally wake. The wake action is slow also,... it will show a bit of the screen like the time, then pause, then open the screen, like the animation to wake is hesitant. And yes, I am using both a passcode AND touch ID. I'd been dealing with this for a few days and it's very frustrating. I started to wonder if my touch ID or the home button itself was going bad, then I decided to test out a theory last night. I turned my touch ID off, but left my passcode on, and I got the same results. THEN, I turned off my passcode too, and as soon as I did that, my wake action went back to normal. I was surprised, because this means my home button is FINE,... it must be the iOS being buggy. But then I wondered, if it was a fluke and if I put my passcode and touch ID back on, if it would be fine now or if it would go back to being glitchy... unfortunately, it went back to being glitchy. I turned it all off and on several times, and in different combinations, with only the passcode on, but touch ID off, and using 4 digit code vs a 6 digit code vs alpha code, etc... but no matter what, as long as touch ID OR passcode is on, I get the glitch. It's very frustrating. So, for now, I decided to keep them both OFF... just so that my phone will wake up properly at least. I'm hoping that the upcoming iOS updates will fix this bug soon !!! Because not only is it highly frustrating, but it's a little scary knowing that my phone isn't passcode protected at the minimum, and another disadvantage of not having it on is that I can't use Apple Pay until I turn it back on. Once I turn that off, my stored credit cards in Apple Pay get deleted (for security reasons, which is good), but I do enjoy using Apple Pay at my stores I shop at that take them :-( I'll take my chances tho for now leaving it all turned off, for the wake of not pulling my hair out having to deal with a 10 second wake to use my phone every single time. Ugh !! If anyone else has this issue, I'd like to know your scenario, and also wondering if you could test out turning your passcode and touch ID off, to see if it works. I'm definitely going to report all of this to Apple. So far, everywhere in forums where people are complaining about the wake being super laggy, no one has mentioned that they tried to turn off their passcode and touch ID. For me... this at least allowed my wake to work, but now I'm not secure and locked. 😟

I’m starting to think the fault is from when I restored from a iCloud backup.

I have tried a friends iPhone 6 and we doesn’t have this slow issue.

I’m going to restore my phone again and see what happens.

It is very frustrating when it happens, as you have to wait SEVERAL seconds (as in a minimum of 7 seconds) to be able to use your phone. Mine does it at least twice a day now. God I hope they fix it I don’t need a new phone it’s not like I’m using a 4s...

Didn’t you read my post? I’m fully aware of that fact!

I’ve clearly stated I can’t downgrade because I’ve already upgraded my watch to watch iOS 4! What’s the point of repeating what I’ve already said?

Serolio I must say thanks to you. I actually purchased an iPhone 6 today while I am waiting for the iPhone X. I did a 100% fresh install of iOS 11 and it was truly awful.

So I followed the 'Reset all settings' trick - and so far it actually worked!!

Thanks!!

@Serolio: Well, I've got nothing to loose so have tried the reset settings option. I am currently trialling it and will see how it responds over the next few days and report back - it is too early to tell at present.

However, as of writing this, IOS 11.03 has miraculously appeared - so it must have heard all the complaints.

I'm installing that now and then we'll see what else it has broken.

Oh, and on the listed bug fixes for IOS 11.03 - it is BLAMING the poor and unresponsive touch display for iPhone 6s users on having dodgy, non-Apple replacement screen repairs!!! I can't believe they just said that - what about the rest of the iPhone 6 users who have newish original phones with no replacement parts except the ones Apple put in there in the first place????

Thank you so much Serelio.

My IPhone 6 became almost unusable after the 11.0.1 update.

The phone beeing 3 years old I figured it could not cope with the new system.

Thanks to your tip my phone works perfectly again.

It actually feels like a new phone, no delays etc..

Thank you!

So after a week of trying out the info supplied by Serolio, and applying IOS 3, I can say that the iPhone 6 Plus has improved no end, so thanks for that - very helpful, but completely illogical, considering I set the phone up with both backups and as a new iPhone - so completely weird.

It is still shocking that they released this version of IOS without proper testing, but thanks for the suggestion and I would also advise others to try the 'reset all settings'.

After some improvement in speed performance after 11.0.3, my iPhone 6 has suddenly become almost completely unusable. The scroll gesture (swiping up or down to scroll up and down pages or menus) doesn’t work. I can select by single tapping, but anything involving a swipe does not register. I can’t swipe the button that appears at the top to shut off the phone, and just pressing and holding the power button will not shut it off either. It eventually just returns to the home screen.

I have been trying to “ reset all settings” but apparently I set my restrictions passcode to something that I would never remember. I don’t know what I’ve done but I’ve tried everything and nothing works, I’m starting to think someone set it as a joke because every code I can possibly think of that I would use for something has been rejected.

So now instead I’m doing a restore from itunes which has been going for over 2 hours now.

This is painful. I’m really upset that a new iOS would do this to a phone. Apple is starting to get really sloppy in some of their decisions and execution.

Why, Apple? Why?

Unfortunately, I doubt this will fix your problem. I also tried this 3 times and also set up as a new iPhone 2 or 3 times with no difference. The only way I got mine to drastically improve was the 'Reset All Settings' option and I can now use my phone. If you have a pass code issue - I think this is going to stay with you until you either erase all your data to clear the passcode and then restore from a backup.

You will still need to use the 'Reset All Settings' after you have restored it though as I still had the issues after 3 restorations until I performed the fix from Serolio.

Thank you I will give this a try.

I’ve finished restoring and swiping now works again, I’ll wait to see how speed and battery life go. If it’s still bad and I still have heat issues then I will be going the full monty and wiping the whole thing.

Cheers

Don't forget - I also did this and no difference at least twice as brand new iPhone - didn't work. Get your passcode sorted and then do a reset all settings - I really hope this works for you too as I was about to give up and bin mine it was that bad.
