A little history from this thread: https://forums.macrumors.com/threads/12-pro-stutter-when-closing-apps.2263484/

  • At some point in iOS 14, we started seeing this animation stutter when swiping up to go home. It was bad and got worse over time (until a device restart)
    • It was so bad in fact that it would often interrupt the action of going home and throw you into the app selection screen
  • It was completely hardware agnostic. It didn't matter what model of iPhone you had or even what apps you were using
  • This persisted for many months. We have reason to believe it was VERY widespread (100%?) and that some people were a lot more sensitive to the stutter than others. I remember seeing it random b-roll on a MKBHD video and no one batted an eye
  • Regular support was unhelpful and often just suggested that people factory reset the device (it only helped for a while)
  • I certainly don't mean to take credit, but after months of it, I was losing my mind. I sent one of those angry emails to the tcook address and a member of the executive support team called me the next day
    • Over the next couple of days, they had me install a special piece of diagnostic software and also run in a super high diagnostic mode for the next 24 hours. They wanted me to log when I saw the stutter. I stopped logging after the first 50 or so
    • A week later, Apple reached out and told me that they found the issue from my logs and are working on an immediate fix
    • A couple days later, build 18E5154f was released and this specific stuttering bug was finally squashed
All good for about a year and a half.

Then, a flash of PTSD when a couple hours after I installed one of the iOS 16 betas, I experienced the very same issue on my iPhone 13 Pro Max.

I immediately opened detailed feedback (that hasn't been touched since beta).

The issue has been in every iOS 16 and iOS 16.1 release since, even to this day.

A couple things to note about this one:
  • It is also hardware agnostic, though maybe a little less so (how quickly the issue surfaces)
    • I saw it on my iPhone 13 Pro Max
    • I saw it on my iPhone 14 Pro Max
    • I saw it on my iPhone 14 Pro
  • It does not seem to be quite as widespread as before
    • I do NOT see it on my wife's iPhone 14 Pro Max (yet?)
      • I looked for any difference in settings, usage, etc. Was unable to reproduce it
This still sucks. It's frustrating that there isn't any noise about it in the media. And it's frustrating to think that we might have to deal with it for another 6+ months like last time.
 
Why hello Plexicle from Reddit ;)
Hello! It's already been a month and a half and several builds where this feedback is ignored. I just don't want us all to have to wait another 7+ months like last time for this to be taken seriously.

@antiga Yes, this regression is very frustrating. It actually started for many people with iOS 13. We suffered with it for over a year until the finally fixed it in 14.4. I'm worried the same might happen with iOS 16. I'm an iOS developer and I sent them feedback and logs for over a year before it was finally resolved. The issue is with how iOS manages memory. In iOS 13, Apple increased the amount of apps that can run in the background before being terminated. That increase seems to have caused some performance hits on the system. Honestly, I wish they would go back to how it was before. I'd rather have a smoother experience than more apps resuming from their background states. It's probably going to take another year's worth of people complaining before they look into it again. My question is how do all the execs (Cook, Federighi, etc.) use their phones on a daily basis and just accept this? Wouldn't they be embarrassed by how laggy/stuttery their new flagship phone is?
 
I notice AOD caused this closing animation stuttering. Stuttering stopped when I disabled the AOD.

Why isn’t there any noise in the media about it yet? Can we do something? I have 3 iPhones 14 Pro Max with this issue. My old 13PM didn’t have it and I had the iOS 16.0.2 installed and later the beta2.

Some people seem not to care about this or say their iPhone is flawless and it runs like butter.

Macrumors can help us! Some YouTuber also can do it. I’ve already sent emails to Apple and reported the bug in several foruns and in the beta program. I don’t have access to famous YouTubers or people inside 9to5mac or macrumors. Can anyone do something about it?

It's simple, Apple is more concerned with new features than something cosmetic like stuttery animations. They also have other bugs to fix that aren't cosmetic. The fact some people either don't have the problem or not notice it makes it even easier to ignore. News sites will report on those other things first.

In short, it's low priority.

Has anyone heard anything back from Apple on this? I remember when we went through this with iOS 14, to took MANY people opening tickets with them before we got any traction. My ticket hasn’t been answered.

Do you have AOD turned on? I replied MKBHD tweet. Not sure whether or not he read or notice it.

Some experience on this issue:

After restart issue is not present until using the phone a while.
How longer the device is on, the stutter becomes more noticeable.
Even hanging more than 1-2 seconds even.

Before I always restart but after you said: do you have AOD turned on I tried to turn it off.

Suddenly the stutter was gone even when turning it back on. It appears after a time so it’s the same as a restart

I also think this issue returned with the AOD feature. Very annoying…

Update: the stutter appears again even with AOD off after a While

Also experiencing this, and it’s very frustrating. Wondering if it’s tied to some setting on my iCloud account - setup as new and still persists.

As the OP said, this had been fine for over a year - I also experienced it on my 11/12 Pro beforehand.

I think it doesn’t have anything to do with iCloud account. My 13PM was perfect with iOS 16.02. You probably didn’t set up as new during the first configuration. I guess some iPhones may have a hardware predisposition that may be aggravated by an iCloud backup triggering iOS 16 issues.

What’s the rational for a specific iCloud setting or account triggering this bug?

Everytime there’s a software bug only some devices show it. This indicates a hardware predisposition. Backup from iCloud always trigger some bugs in apps. Apple support recommended against backup in the initial, first configuration for this issue.

Does Tim Cook’s and the Others’ iPhones have this issue? I bet they don’t.
 
I’d like to know the reasons why it could be related to ICloud itself and not the backup. It doesn’t make sense to me and it would have no correction at all.
 
A lot of people in this thread claims they don’t have the bug. Surely they didn’t change any ICloud setting previously.
 
I had all iPhones since S Jobs introduced them. The problematic one was the 6S Plus which had a blur on the display. Every single unit had it, but almost nobody could see it. I’ve never seen a bug like that and I am totally disappointed at Apple. I’m having some Samsung thoughts, what is in incredible for me.
 
As noted, I don't see it on my 14 PM and I have iCloud backup turned off.
Thank you very much! I’ve disabled it on my iPhone.

Everything I’ve alreadydone to try and fix this (nothing works for more than a few hours)


1) Force restart
2) Turn off and then on
3) Delete IPhone and set up as new. (But I cant go back in time and do it during initial configuration)
4) Change system language
5) Update software
6) Try all betas
7) Turn off always on display
8) Delete some apps like WhatsApp
9) Change and delete widgets
10) Change background picture
11) Turn off deep effect
12) Log in to other ICloud account
13) Change iCloud settings.

Next: Throw out of window (Defenestrastion. Almost there!) and buy a Galaxy S22. Nope, no way. I’d rather buy an IPhone 13PM.

If we could feed this list and send it to Apple, maybe they could acknowledge it. People and companies have difficulty saying I’m sorry, I’ve made a mistake.

No better explanation than multiple defective units prone to this iOS 16 issue which may be trigger by a backup from iCloud.
