    Interesting how there's usually a group of people with issues for every major update who end up calling the worst update ever. Only for later updates to that version to then be praised as an example of perfection when the next new major version comes out which is then called the worse update ever. This has all happened before, and it will all happen again.

    Just because they don't go online to complain about it doesn't mean it's not happening to them. Millions more won't notice it or don't have time to report it online and just go directly to their carrier or an Apple Store.

    I can get my work done much faster due to the different inertial scrolling in iOS 11. Therefore I find iOS 11 faster than iOS 10.3.3.

    But maybe for most people they don’t notice the milliseconds difference. I find iOS 11.1 great to use and in my circle anecdotally no one has complained iOS 11 has slowed down since iOS 10.

    Incorrect. There have been plenty of updates in the past that changed the face of the phone. Moved apps. Allowed for new features. iOS11 was rushed. The iPhone 7s/8/X was not thought through clearly. Maybe it was but there are so many issues from the start which to the public, looks and feels like a failure. I completely agree with all heavy Mac fans and users that there have always been hiccups in the past with new operating systems, including MacOS. Numbers of times, year after year, the new operating systems for desktops have been **** until all the bugs were sorted out. Cool. That's great. But why do you run a business like that? Your one of the top businesses in the world and have billions so why not spend money to properly test everything before launching it to reduce on the amount of bugs and issues?

    If you do a survey of everyone on this forum on all 377 comments and do comparisons on who is using what device, how many apps they are running, how full their phones are, how quickly they move from app to app, that is where you will separate people on this forum. The hardcore users, the ones who use their mobile device to control their life (Email, Texts, 3-5 forms of social media, business, games, etc) These users push the device to it's max. WHEN and I'm saying WHEN . . the iPhone6s came out, it was amazing. It ran flawlessly. There were not a long list of mistakes and operating system issues. The 7 came out. Still no problems. No slow downs. iOS 11 dropped and all of the sudden everything went wrong with older versions of the iPhone. Some users were so disgusted immediately after upgrading that they dumped the phone thinking the phone couldn't handle updates any longer and bit the bullet to upgrade to the 7s AKA the 8. Apple sale tactic? Who knows.

    All I am saying is out of every iPhone I have had, and I have had every phone since the beginning along with all their updates and operating systems, iOS 11 has created the most problems, including massive slow down of most apps, freezing of apps, battery life issues, etc. The company may still be moving forward financially but their innovation and creativity are dwindling down and falling apart.

    And yet all that I've said has been happening and will continue to happen nonetheless.

    Okay,

    I found out something after my long days of research. It worked for me, but not sure if it will work for you.

    I had opened all my unopened text messages. My speed has been increased by 50%. Am using Iphone 6 128 GB. After ios 11, it used to take 15-20 seconds to open google maps or photos, now it is opening in 5 seconds. Camera gets active in 5 seconds and it used to take more than 20 seconds before.

    I can feel that apple written a code to open or check the unopened messages in background or in the foreground particularly after restarting the phone and even after its idle. I would like to clear my calender as well, but i couldn't afford to do.

    Hope this might be helpful to someone.

    It's not re-indexing. It's bull ... Unless mine has been "re-indexing" for the past month or whatever.

    So, anyone affected by this got a better experience with iOS 11.1, which is now out?

    Dude, I posted that over a month ago. Mine has been back to normal since the day before I posted it. I'm not experiencing any slow downs.

    On 11.0.x my experience with my iPhone 6 was horrible. On 11.1 it's just bad, so it's definintely an improvement.

    Man iOS 11 has been a roller coaster sometimes it’s fine but iOS 11.1 is even worse on my iPhone 6s Plus the performance an everything is good its the battery life thats bad I am incredibly annoyed an frustrated with Apple right now my iPad mini 4 an iPad Air is running perfectly fine with iOS 11 in battery life there’s nothing wrong with my iPhone 6s Plus for some ppl it works good for them for some it’s not I’m annoyed that I can’t downgrade back to iOS 10 an the ppl who have major battery hit in longevity are supposed to just deal with it, well my contract is almost over an Apple just ignores this and continues to mainly focus on the iPhone 8, plus an tre iPhone X cuz it seems like ppl hat have battery issues is on older iPhones I feel like Apple did this purposely to get ppl to buy newer iPhones but I am Gunn’s go back to android if they haven’t fixed iOS 11 on my 6s within a month or two because I can’t even get through half a day on full charge it dies within 2 or 3 hours of usage...truly disappointed in Apple I was so happy when I first switched to Apple few years ago but now they are becoming careless and focused mainly out killing off older iPhones an making ppl buy new models its sad my old Samsung galaxy s4 battery life can last longer then my 6s plus now an the ppl that say Apple doesn’t make older Apple devices slower u clearly don’t know anything.

    On my iPhone 6, I had a half-day of slowdown issues (this was after iOS 11.0.1 was installed and the phone was re-indexing ifself) but the phone has worked fine with no issues with iOS 11.1.

    Wow, I updated my trusty iPhone 6 the 3 days ago and since then it’s been driving me crazy. Accessing Podcasts (and most other apps) was painfully slow. That was until of course infound this thread. So simple to hit the Reset button.Ta

    (Settings --> General ---> Reset --> Reset All Settings) - no data was lost

    Sometimes I get 5/6 seconds to open the settings app. Lovely!

    Doesn't work. Also, as a developer, I reset the device on a "regular" basis. iOS 11 is just too heavy for this device to be smooth. Even the 6S struggles with simple animations...

    Didn’t see that you’d tried it. Didn’t see your device type.

    I’m very pleased with the performance of iOS 11 on my 6S, I presume you’re on a 5S or a 6. Less than one second to open settings. I have noticed the unlocking animation is a little less fluid though, not always; a lot of times it’s perfect.

    Just upgraded to an iPhone X. I can confirm that the 6S lags a little bit on iOS11 compared to my X. I think it's a no brainer that Apple will passively push users to upgrade to newer hardware :)

    Couldn't agree more except for me this was the last straw and I'm obsoleting Apple from my tech stack. Too many of my devices have suffered the same fate and I'm done. Been curious about those Droid things anyway and variety is the spice.

    Reindexing for three weeks?! It's permanent. The bug that's keeping me from being able to directly share something via messenger (e.g. a photo from within photos) is also very real. Super disappointing "upgrade". Compatibility testing of software is a thing, it's part of my profession as a software engineer. Clearly Apple has chosen to emphasize forward compatibility a la hardware purchase.

That's exactly what I'm going to do. Hello Moto. ;-).

    So Apple has apologized for the slowdowns, the question is, what are they doing to fix it?

    I'm on iPhone 6, 64GB storage, 40GB free, iOS 11.2.1 (latest update for OS and all apps). I've done all the recommended things, like
    • update all apps
    • shut down open apps (always!)
    • hard reboot (hold down power+home button)
    • clear cookies / Safari data
    • turn off Automatic Downloads
    • disable Background App Refresh
    • limit Location services
    • Reduce Motion
    • disable widgets
    • disable Siri
    but it's still annoyingly slow.

    I've been using the iPhone almost a decade, starting with the 3GS and iOS 3 (!) and from time to time I've seen certain features get slower, mainly
    • Chrome - starting around the time of iOS 9 it became uselessly slow. I suspect either Apple or Google hobbled it, in their war to undermine each other, and we end up suffering
    • Notes - in the old days (before 2014 maybe?), I used it a lot, and had like 2-3000 notes on the iPhone, and even on the 3GS it was fast. But after Apple introduced the new Notes format and iCloud, things got slooooow. I deleted everything, and now with just 150 notes (none very big and all just plain text) the Notes app still can take more than 30 seconds for things typed on the keyboard to appear on the screen. It's bad. A while ago I switched to OneNote, which also is slow but has more features.
    but nothing like this.

    The big complaint I have is
    • Camera - the most noticeably affected function under iOS 11. When you start it up, the screen stays black for 5 up to 20 seconds before the camera starts working. Before iOS 11, the camera would start pretty much immediately.
    The thing that gets me is I've only had this phone about a year (free "upgrade" via phone insurance after my iPhone 5 died) and it's already outdated? I had the iPhone 3GS for like 4 years and it was always fast enough and stayed useful the whole time! All it ever needed was a new battery. The iPhone 5 was only useful for about 2 years before I noticed things getting slow. Now I've only had the iPhone 6 for one year and it's annoyingly slow. Are we seeing a pattern? At this rate, can I expect the 7 to become "obsolete" in 6 months, the 8 in 3 months, and so on? :-O

    This kind of thing makes me resent Apple and consider changing over to Android, but I tried that and it was painful. VERY painful. There's nothing like the iPhone. Then again, with Windows phone gone and no Linux phone, it's not like there is any other alternative!

    Makes me wonder if there is a reindexing bug. Could some people be stuck on that? Mine has NOT returned to normal

    Thanks for posting this. It's very similar to my issues, albeit with a different phone and mine is completely brand new!
    Apple just sent me a brand new iPhone 5s instead of replacing the battery. Didn't even know they still had any. But similar problems, exacerbated by them forcing IOS 11 on it, which slowed everything down. :(

    The way to rule out throttling is checking CPU clock with CPU dasher x (appstore)

    All the recent things in relegation to power management changes that can throttle the CPU aren't really related to the iOS 11 release. The changes were introduced back in iOS 10.2.1 days for some devices, and expanded to some more devices with iOS 11.2.
