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
Replacing the battery is the only way for your phone to regain full performance - and that at all battery load levels.
I just had this done this morning. Now my phone runs at the nominal CPU frequency (1400MhZ) just like when it was new.
There is no "big mess" to solve. All Apple did was to gradually reduce CPU speed as the battery degraded to protect it and extend its life (and prevent sudden phone shutdowns).
Have you tested the battery? Call Apple and they can test it. Or get the iPhone app Battery Life, or the computer app Coconut Battery.
Yes, it will!
If you have an iPhone 6/6S/6S plus that is close to two years old, replacing the battery WILL restore your iPhone to normal operations!!!
Apple has āofficiallyā admitted that is was purposely slowing down the CPUs in ONLY all iPhone 6 and iPhone 6 variant models to preserve the continuous working of these iPhones that had older, aging degrading battery performance issues, by the time of the introduction of iOS 11!
Apple has admitted this and HAS implemented in the U.S. (soon to be introduced in other countries) a reduced priced battery replacement plan for ALL iPhone 6 AND later iPhone models!
The iPhone battery will only cost $29 U.S.D. ( the normal iPhone battery replacement cost is $79 U.S.D., a savings of $50 U.S.D.) and WILL return ANY iPhone 6 or iPhone 6 variant back to its former, normal operations and performance speed!
This reduced priced iPhone battery replacement program will stay in effect until December 2018!
Stop treating me like some sort of village idiot!
If you have a two year old iPhone, get the battery replaced as soon as you can!

I guess some people would prefer that their phone shut down randomly.
I'd prefer that my phone shut down randomly once a month (which is what it was doing) than that it be very slow and difficult to use every day of the month.
Even better would be to have iOS tell me that my battery needs to be replaced, and that my iPhone performance will be compromised until I replace the battery. That feature is coming in the next iOS update, thankfully.
Best of all would be if Apple didn't push the CPU+battery combination to its limits, so that iPhones could continue to operate at full speed for several years, even as the battery ages. This used to be the case, but with the CPUs in the iPhone 6 and 6s (at least) they began running into this problem.

If my laptop is being used on battery power, I can choose to allow the power management to reduce the CPU and other hardware performance and use it longer, or I can disable power management features and use the hardware at full performance capability up until the last few % of power remaining before I get the critical warning and it shuts down - I know the consequences, it is my choice. I would never intentionally buy anything that did not give me this sort of choice.
The problem is that iOS devices with weak batteries don't give you critical warnings - they just shut down abruptly, frequently with battery percentages of 40% or higher. They don't give you warning. If you go back to before 10.3 was released (the first version with this feature) there are constant reports and complaints in the forum about devices abruptly shutting down, usually during phone calls or video games. Those complaints have pretty much disappeared. Laptops with weak batteries have the same problem, and any other battery powered device with batteries that have developed high internal resistance. I've had laptops fail this way many times over the 20+ years I've been using them - until I got my 2 Macbooks. The oldest is from 2010. Neither has ever failed this way.
How old is your iPhone 6?
They were discontinued in March 2016.
If you purchased and iPhone 6 anytime in 2016, your iPhone 6 is going on two years old.
Apple has already admitted to slowing down all iPhone 6 variants with degrading performng batteries.
Apple has the new reduced priced IPhone battery replacement for iPhone 6 and later models for only $29 U.S.D..
So, make the appointment and get a new replacement battery.
The replacement battery WILL restore your iPhone 6 to its former, normal performance under iOS 11.
Good Luck to You!
If your iPhone 6 battery is bad or not performing at a certain threshold of acceptable performance, this iOS 11.3 update does NOTHING to change the condition of your iPhone battery!
If you turn off the CPU throttling and your iPhone 6/6S/6S Plus starts having random shutdowns due to CPU and battery overload, you will STILL need to have your iPhone battery replaced!
If you think your phone got faster with iOS 11.3 and you haven't disabled the throttling, then, the difference is not in the phone or it's behavior but in your perception.
When you install iOS 11.3 throttling is disabled automatically. You don't have to take any action to turn it off. Throttling will only be turned back on if your phone has an unexpected shutdown.
So, this is not perception or imagination. iPhones with old batteries that were being throttled under previous versions of iOS 11 get an immediate performance improvement when iOS 11.3 is installed, even without a battery replacement. Of course, if you experience unexpected shutdowns or other battery problems, throttling will be turned on. At that point you can live with it, you can turn it off and take your chances with shutdowns, or you can replace the battery.

what happened to this fix you speak of?
Make an appointment at your local Apple Store and have your battery evaluated.
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!
Did you try restoring as a new phone and NOT restoring from the backup? I have a slow iPhone 7 plus and this is my plan to fix it. If it doesn't work, I'd have a faulty phone I wouldn't be able to sell anyone because they'd be going through the same process and ending up with the same slowness.
It's still about choice and laptops don't do that - the iphone 6 does!
Let's get real - we know that mechanical hard drives fail - it is a risk, that's why we take backups of our critical data. But with power on laptops the user can manage power features from CPU usage to suspending USB ports and just about every other battery saving feature - we have choice and almost infinite reconfigurability of the power saving features. We have no say currently on the performance-throttling situation with the iPhone.
Now, had Apple instead opted to say something like the following, do you really think we'd be having law suits, class action and thousands of complaints if they had been upfront and honest to start with?
"Hey everybody, we'd like to share something truly remarkable with you today.... (š) We'd like to tell you that our incredibly designed iPhone hardware and software has a bug, flaw, design fault new feature. When your battery starts to get old, is not fully charged, or cannot hold a full charge any more, it may cause your phone to malfunction or crash. However, this new feature we are introducing will automatically reduce CPU / GPU performance of the phone to prevent this happening. We appreciate this is not what you want to hear and realise that your phone will start slowing down, the keyboard response will lag, apps will crash or stop working - but hey! we are giving you the choice to enable or disable this feature - so you are always in charge - and remember, we care....š"
Ok, maybe not so sarcastic as that, but what I bitterly dislike about this entire fiasco is that I spent months and months with these problems, with a phone that was effectively non-operational, wasting my time, troubleshooting, listening to crackpot BS theories, solutions and the 'Apple can do no wrong' worshippers blaming users on their usage habits, with no acknowledgement - nothing but silence from the people in the big apple that knew about this and did nothing to explain the deliberate throttling until just recently, culminating in an almost unheard of apology.š®
So now, lets wait for the 'fix'. If people will be given the choice to disable the feature if desired - great - if they don't like it they can always vote with their wallets and that will be their choice too. The condescending 'we know what's best for the plebs' attitude will always backfire in the end.
My iPhone6 worked perfectly fine - up until the iOS 11 upgrade. Only now, after the upgrade, do I have a "slow almost inoperable iPhone".
So, yes, I am looking forward to a iOS 11 fix that lets me diable Apple's throttling down of my iPhone CPU so it becomes usable again.
To be clear, I have never had the sudden crashes.
I am also going to take advantage of the cheap battery replacement offer. Why would I not ?
Make an appointment with your ālocalā Apple Store to get a new replacement battery for your iPhone 6.
Hereās what to do here in these Apple website/webpage links.

Good Luck to You!
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.
The full story is here: https://www.macrumors.com/2018/01/17/tim-cook-on-iphone-battery-controversy/
You forgot to mention that Tim Cook also promised an option in the upcoming IOS 11.3 for owners to DISABLE this CPU performance crippling feature!
He is giving the owners a choice to use it or not, something we currently have no control over.
And let us also not forget that this performance throttling āfeatureā will NOT be limited to iPhone 6 models, but will be applied to ALL iPhones in future.
iPhone 6 very slow with IOS 11 update
