Home animation lagging in iphone xr ios 15

I can confirm this issue as well on my XR. I am experiencing very annoying stuttering in animations ever since I've upgraded to iOS 15. As others mentionned, I've also tried IPSW restore without restoring any backup, and this didn't resolve the issue as well.

I'm glad other A12 users are experiencing the same issue as me, and hope Apple ever addresses it. I feel like this "upgrade" ruined my iPhone for little new features.

I've noticed the battery life being worse as well. I think it relates to the "CPU core theory" , where iOS 15 would use eco cores ineffectively causing animation lag. If that's the case then Apple might have tried fixing this by just enabling the power cores to do the animation instead. But as a result there is worse battery life.

Yeah I herd it happens on and off with all gesture model phones at least Xr and up. People that have the XS max (my phone) report not having it so it seems random. A iPhone 12 I tested also had small stuttering when swiping up from intensive applications so it’s there just not as visible.

Regarding this,

i read in forums that Reupdating ios 15 through IPSW (without restoring) is fixing this lag issue for XR. Can someone try and confirm this ? Am not having my pc with me.

update : the IPSW method is not working, I tried it again.

I request all of you to send feedbacks to Apple regarding this issue so that it can be fixed soon.

we all must report about this problem to get solved

No. I witnessed 11 pro original apple battery, the health written 22%, ans still in good performance. Smooth as it should be. It's not battery. Mistery

I am facing the same issue on my Iphone XR after updating to IOS 15.0.2

Animations have become laggy.

Storage is 45GB free

Whenever I open Apps or Switch Apps from Recents Tab, The UI Becomes stuttery.

What should be done can somebody help ?

it is so annoying!!

The same thing happens with my iPhone XR. As it was said above, neither resetting nor flashing helps. it seems to me that we are unlikely to be heard by the Apple. The first time I encounter such freezes in the iOS.

I reported the issue in the feedback app. That's the only way to reach them. But I have very little hope that this will ever be addressed 😞 since this is occurring to few phones and fewer people out of them would even notice this and even fewer people out of them actually escalates this issue in forums. So yeah! It's hard to get it to Apple's attention.

Even on the iPhone 13 is this present? Strangely enough, I thought it was happening on older iPhones, like XS, XR, maybe 11 the problem with freezing and stuttering of animations and applications. Do you have the same problems on a iOS 15.1?

Yes it is, it happens when I have many apps opened in the background.

when opening or closing apps there is a frame drop, scrolling down or up goes at 40 fps or so and opening or closing the camera is very laggy

it happened on iOS 15, 15.1 and 15.1.1

Unfortunately I have the same issue on my iPhone XS. I even changed the battery, because I thought it might be the reason (it was 78% of original capacity). After change I felt it is super smooth, but after some time this swipe lag is back there. Any ideas how can we push it to Apple? I see that many models are affected...

I have the same problem with iPhone 11 as well. The jitters are everywhere. From Twitter to the App Store. Swipes are horrible.

Bought the phone last December because it was still at the lineup and it had the same 4GB ram as iPhone 12 and iPhone 13.

Sadly nope! It's a big disappointment. Feeling hopeless that if it'd ever be fixed hereafter when it's not fixed even in a dedicated .X bug fix update of around 1GB. I guess it's time to stop dreaming about a fix and start getting used to these nasty stutters or to buy a new 'new' iPhone. Clearly apple isn't listening 😞
