iPhone Users Complain of App Slowdowns and Performance Drops After Installing iOS 11

Wanted to chime in with a me-too. No issues so far, and in some small cases - faster app performance.

Nothing personal, but the “me too” responses aren’t particularly informative in tracking down ephemeral issues or those affecting a minority of users. When these issues crop up as they inevitably do, there seems to be a general attitude that being unaffected is a tacit denial of the existence of the issue.

Now, if you were to specify, say, your phone configuration, your carrier, if you had been running the beta, etc, etc that might be helpful.

But I can absolutely say that the issue is real and not in a subjective sense that things feel slow. Bad enough to essential render a phone unuseable*

Again, nothing personal!

* haven’t yet had a chance to do normal diagnostic steps yet as it’s not my phone and not physically in my presence.

Me-too as in me-too to who I quoted. iPhone 7+ and did not run the beta. I have the beta on my iPad mini 2 and have not seen battery issues there. I don't really care if you found my me-too useful. I wanted to throw in my 2 cents that so users are aware this isn't a universal issue.

I blame the Russians
but serious...I see some "sticking" when doing things...a 2-3 second phase and then a frantic catch up...like in typing. Something is not finishing its task and then handing off

Yup, experienced this today on an iPad. Animations seem janky, control center, notifications don’t register as smoothly...I wish I would have waited.

I’m absolutely going to wait for the update after High Sierra for MacOS...I don’t need a three way gang bang.
 
I'm on an iPad Air (1). I can't say it was the fastest machine on the planet, but I could always get the job done. Since iOS 11, it is slow as hell, the screen for some reason is not responsive (touch the app icons, nothing happens). Battery life is weird, last longer while watching Netflix, but drops pretty fast as soon as I lunch any other app. I got a 1%/minute drop while reading a few feeds on Reddit...
Bluetooth keyboard is hit or miss, it disconnects quite often.
Not really happy with this update.
 
I went back to iOS 10. My battery life was ridiculous. And everything I did was at least 25% slower. I'm not falling for this again.
- iPhone 3G iOS 4
- iPhone 4 iOS 7
etc.

I learned my lesson. Go back while you can, or you will be stuck with lag forever. I just extended my iPhone 6's life for another couple years.

Planned obsolescence? Yeah, iOS11 is super slow. I love my iPhone, but seems like a sales tactic.

I find now however that the issues are related to slow unnecessary animations apple puts in. These appear to run slower on older hardware too. Another thing related to the animations is that apple is locking the screen input during these movements, so it takes longer to start using an app after unlock vs older iOS versions.

Speed should be number one in UI and taking a hit there for no real extra gains looks darn suspicious.
 
I have no issues with iOS 11 on my iPhone SE. Some minor (mostly cosmetic) bugs, but it's overall as fast and stable as iOS 10.

It's a very different story on my admittedly ageing iPad mini 2: everything's much slower, and I encountered a bunch of bugs that were severe enough to force me to restart the iPad. I'll probably try to completely reinstall the iPad from a backup (that can help with some issues), but I don't expect much.

Hmmm if you don’t mind you could screenshot the latest messages so you have a reference of where they left off. Apple turned off iMessage in iCloud for now.

No thanks. It's a UNIX based OS, wiping and restoring should not be and isn't necessary. Fix the issues which are causing the problems.

I believe people who are claiming a full wipe and setup as new phone have something else going on as in it's either in their head the performance improvement, or on the phone something needs to be adjusted.
 
My 6S is doing fine. Apps and overall usage has been even more snappy. I have found a few little bugs and had it glitch on me occasionally. The biggest downside for me is my battery which was bad is now worse.
 
I have a 6S with iOS 11 which I use as a test device. My daily driver is an SE with iOS 10. Both phones have the same processor and should have equal performance. The camera app definitely opens slower on iOS 11.
 
I've noticed everything mentioned in the article even after trying a restore. It is not re-indexing. There are many bugs in iOS 11.

I have an iPhone 6, surprised they even included it in the list. Not gonna upgrade

Anyone knows how to prevent iPhone from auto downloading the upgrade?

iOS10.3.2 jb wasn't broken here - no reason to fix it.
Little appetite for that huge control centre, endless appstore scrolling, health-, home-, car-, research, or animojie kits, -libraries, -extensions bloat
Neither for a notch. And my home button is super.
Happy Halloween !

iOS 11 seems indeed to either run into RAM/CPU limits. Upgraded my iPad mini 4 and noticed significant lag when switching apps -even with only 2-3 "background" apps (background app refresh is disabled entirely, so RAM consumption should be rather low). Upgrade to iOS 11 has been performed using iTunes, so that's as clean as possible. That said, I don't care about the lag. Although, I would still apprecate if Apple would allow real multitasking, i.e. leaving Apps selected by the user running in the backgroud and put 6GB RAM in the iPads to deal with the increased RAM usage.

Agree. iPad mini 4 is well equipped CPU-wise but as most Apple stuff, RAM-underdimensioned.
iOS development isn't meant to make full use of resources - rather requiring more.
 
Hmm - I haven't had any such problems and I've been on it since the first beta. Wonder what makes the difference.
