    So IOS 11 has completely crippled my iphone 5S. Everything has slowed to a crawl. The phone lags constantly. The screen freezes for long periods of time. The phone completely reboots often. Apps crash, the phone crashes, everything is now completely miserable. Not to mention that less than 24 hours after updating, my battery swelled up and had to be immediately replaced. I should say the phone was working 100% perfectly well before the update.

    So, go back to 10.3.3 before it's to late.

    Is that possible? And advised? I've heard trying it bricked some phones. And how do you do it anyway? Are others having the same problems and is this the best solution? What's the consensus?

    You can roll back to 10.3.3 before it's no longer being signed. It Has to be completed through iTunes.

    Something went wrong with the install it seems. Might be worth reinstalling. Going back to iOS 10 is an option as well (for now at least).

    It is completely up to you whether downgrading is a good idea. It won't brick your phone but it does require a backup from iOS 10 if you want to keep your app data. Just be advised that downgrading is only available for a limited time. Here's a link on how It's done: http://osxdaily.com/2017/09/20/downgrade-ios-11-to-ios-10-iphone-ipad/

    Hi,

    It might be worth you trying a DFU mode re-install of iOS 11 in iTunes first, and see if that helps. My iPad Pro 9.7" was behaving terribly: random resprings, taking about six seconds to unlock, and huge lag and sluggish performance all over in general. Last night I took an encrypted backup in iTunes, did a DFU re-install of the 11.1 beta image, and restored my backup. After that all these problems went away, and it's been as smooth as butter and behaving like I'd expect an iPad Pro to, performance-wise. So this couldbe something you might want to try before you put 10.3.3 back on, as you'd have to use iTunes to do it anyway.

    My 5S I have for work was having a tough time on iOS 11. I did an iCloud backup/device wipe/iCloud restore, and it is running MUCH better. Granted, I was on the last few betas with it as well, to test some work-specific apps, so it may have been something to do with the beta cycle, but either way it is running good for what it is (4 year old hardware).

    I have upgraded my 5S to iOS 11 via iTunes and it is running smooth so far. This isn’t going to help you now, but just letting you know it should run iOS 11 without problems.

    Hmm I also would try to reinstall. iOS 11 feels better on my 5S than it does on my Air 2.

    I have upgraded my wife's 5S two days ago and performance wise it's ok (not noticeably different from iOS 10.3).
    Battery life definitely is reduced by about 15%. I hope Apple will address this point.

    10.3.3 is as well, it stopped being signed on Wednesday, then magically on Thursday it started being signed again and has been ever since.

    Questions: What is DFU? And does installing the latest updates work the same as a reinstall? Or I still need to do a total reinstall? And should I reinstall the latest update or stick with 11.1? And for the reinstall, is iCloud backup/device wipe/iCloud restore recommended? And what method to use to wipe the phone? Thank you all! This has been a helpful thread and hopefully will work.

    Hi,

    DFU mode is Device Firmware Update mode. Basically it's as close to a format and re-install as you can get in the iOS world. It bypasses the boot loader and re-creates everything it's possible to re-create from scratch, essentially over-writing the current contents of your iPhone's OS storage with a clean OS image. It's not actually as scary as it might sound, however, and is an entirely Apple-supported method of re-installing iOS via iTunes.

    The basic procedure would be:

    1. Connect your iPhone up to iTunes in the normal way.
    2. Whilst still connected to iTunes, hold down the power and home buttons on your iPhone simultaneously.
    3. Keep holding both buttons for ten seconds. You will find after a few seconds the screen goes blank.
    4. After the ten seconds have elapsed, let go of the power button, but keep holding the home button.
    5. iTunes should eventually report it has found a device in Recovery Mode, but the screen of your iPhone will stay blank.

    At that point, you can let go of the home button on your phone. In iTunes, click the Restore button, and iTunes will re-install your iPhone. Note that this will entirely wipe everything in local storage, and basically make your iPhone factory-fresh again. So if you want to keep anything that's currently on it, make sure you have a known good backup before doing any of this. Once the iPhone is re-installed you'll have an option of restoring either an iTunes or iCloud backup, or setting your iPhone up as new.

    Hope this helps !
