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
HERE'S THE FIX: Go into Settings> General> Reset> Reset All Settings (this will reset iOS settings, won't touch your apps)
WHAT THIS DOES: This will *not* erase your phone, but will reset most of the things you can adjust in settings on iOS (you'll need to re-enter you wifi, adjust notifications and privacy settings again, reset your default account for Calendar and Notes, etc, but all your email accounts and iCloud account will still be logged in and all working).
FIXES THIS ISSUE: I had the same issue: iPhone 6S. Upgraded. Even with 25GB free, I'd press a button and often have to wait 1-3 seconds for a response, or copy and paste selectors would be really slow to appear, even the keyboard was unresponsive... phone was barely unusable, literally. I think most people don't get it because most who updated to iOS 11 noticed it being a little slower but not 90% slower. Those like us need to take this step.
BACKGROUND: When I was scouring I found that erasing your phone and restoring from backup worked for people on Reddit, and that should be reliable. I was in the process of doing that myself and accidentally chose "reset all settings" instead of "erase all content and settings". My phone rebooted and all my apps are fine, just needed to go through iOS settings and readjust things.
ALTERNATIVES: This is obviously better than either (a) downgrading to iOS 10 or (b) making sure your phone (as it is now on iOS11) is backed up to iCloud, erasing it, and restoring from that backup.
The difference in speed is shocking.
Pretty sure this will work for you too.

Apple Does Make Your iPhone Slower As Its Battery Gets Older
I checked with a couple apps and I fall into this category - will be going to an Apple Store on Friday to get a replacement battery (iPhone 6, 3 years old). I'll report back.

Wrong. My battery isnt old at all, i got this phone last year. It is deliberate cpu throttling with perfectly capable hardware.
Battery age is not a question of months or years but of charge cycles. Depending on how and how much you use a phone, a battery can begin to show age after less than a year or last for two or three or four. Download the app Battery Life and see what it says about the health of your battery. If it indicates that it's failing, contact Apple for a diagnostic.
I still haven't updated to iOS 11 for fear of a slow phone. So when I do, I'll follow all the suggestions here. If its still slow, I'm gonna take the iPhone 6 to Apple and have them deal with it. Whatever the cost, it'll be cheaper than buying a whole new phone.
Download Battery Life and/or CPU DasherX (both are free) and check on your battery condition. If Battery Life says your battery wear is high or very high, get the battery replaced before upgrading. Definitely cheaper than a new phone!
I think that there are at least 2 different issues here. There are phones with worn batteries and there are phones with relatively good batteries (like mine, at 91% factory level as reported by Coconut Battery). In my case, my iPhone 6 was very “laggy”. Apps took a long time to launch, “Hey Siri” was very slow to respond, keyboard was ”laggy” and home button occasionally unresponsive. All of these problems were resolved by resetting to factory state.
Even though CPU Dasher reports CPU running at 600 MHz when battery is low, those problems have not resurfaced.
Yes, the phone seems a little less snappy (subjectively) then before. It is not bad.
I really think that people should give the factory reset a try if their batteries are in good shape. I think that Apple considers a battery needs replacing if capacity falls below 80% of new.
This, as most of us here already suspected was a deliberately engineered slow down and has now finally been admitted: Statement.....
A Message to Our Customers - Apple

So time to get in the queue for a new replacement battery.
I still think the user should have the choice of whether to throttle the CPU / GPU performance though, as this is the one main thing that is making the phone unusable for me - the slow laggy display and response times of doing nothing more than trying to scroll through an email - forget Landscape zooming in Safari, it just freezes, App store won't load - takes 2-3 times of closing it before it opens. All immensely annoying.
So thank you for the apology Apple, though a long time coming.
This is not exactly true. Replacing the battery will stop the phone from reducing CPU speed and improve performance a lot, to the point that the phone is usable again, but it will still be far from buttery smooth as it was with iOS 10 (at least with an iphone 6, maybe faster phones do fine).
I've had a slow, buggy iPhone since updating to iOS 11 and my problem was solved by completely wiping my phone. I said I was going to do this in earlier posts and just wanted to confirm that it did solve the problem. I did not restore from a backup since I was told that this would not resolve the issue. I set it up as a new phone and just re-synced with iTunes to get my music back and logged back into iCloud. Be sure to backup all your photos and videos and anything else you want to keep before doing this. I'm not saying this solution will work for everyone but it did for me.
You can't restore a previous version of iOS.
Apple is currently testing iOS 11.3, which will allow users to control the speed-throttling feature. This feature was implemented to prevent unexpected shutdowns by iOS devices with old batteries, but unfortunately it also degrades performance. When iOS 11.3 is released, users will be able to control whether this feature is turned on. You'll be able to choose the tradeoff between speed and safety.
If you want early access to this release, you can join Apple's iOS beta test program. The new feature was just made available to developers today. If Apple follows its usual pattern it should be available to the public beta testers in the next few days.
8 Days later my wife iPhone 6 still working like a new iPhone after the Apple replaced the battery for $29 bucks. I know it might be difficult for some folks to get to the apple store for the $29 dollar replacement, I had to drive an hour to get to the closet store, but i found a few things to do while i waited the hour for them to replace her battery. She is happy with the performance and no issues with slow downs.
Just checking in a few weeks after my wife's iPhone got a new battery, it has still been working like new, only costs $30 bucks, and a 1 1/2 wait at an Apple Store. She has an iPhone 6, her old battery had many cycles on it, and after the battery was replaced, no troubles, all apps work very fast,
I had the same experience. It's like night and day. I have my great old fast iPhone back. It just goes to show how much Apple messed up the operating system update.
I highly recommend anyone with performance problems upgrade to iOS 11.3 to get this fix.
Latest iOS upgrade 11.0.2 resolved my "super slow" mode on my iPhone 6s+.
I update software on my Iphone 6s+ today. Ufff it's faster than before.
Please update your device to the latest iOS version 🙂
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.

Serilio posted the fix: above: Go into Settings> General> Reset> Reset All Settings (this will reset iOS settings, won't touch your apps)
I’ll follow up to say that my iPhone 6 condition continues to improve with these steps and updates. I previously posted on the extreme slowness of my device after installing iOS 11, but I found that this improved significantly after performing a Reset Settings as suggested by Serolio.
Since then, I installed 11.1, and found that speed improved even more after the installation. It is almost back to the perceived speed of my device in iOS 10. I don’t have any more granular information to identify if this is due to 11.1, or just an overnight installation process itself, but can only contribute my empirical experience. I’ve had the device on 11.1 for ~48 hours, and it has been experiencing “normal use” (extensive emails, web browsing, social media, etc.) throughout each day. Much much better than the initial iOS 11 installation.
