Home animation lagging in iphone xr ios 15

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!!

Exactly! Currently on iOS 15.1. My XR, which has 92% of battery capacity and with moderate usage, drops exactly 1-2 frames while swiping up to go home from few apps like browsers (in iOS virtually all browsers are safari reskinned), camera, YouTube etc., Especially Safari!! Every single time I'm able to reproduce this swipe up lag. I tried literally every single remedy I could think of. Settings tweaks like turning off live text, tweaking touch accommodation settings, Soft reset, hard reset, settings reset, factory reset, clean install iOS via ipsw with backup restore with iTunes and even without backup restore, clean install of iOS via iTunes under DFU mode! Nothing resolves this issue. Absolutely nothing!! Couldn't understand what's causing this. Being a Sucker for performance, I couldn't tolerate this frame drop in my otherwise flying iPhone XR!!

Tried to replicate the same issue in my wife's 12. I couldn't which obviously means that this is an OS optimization issue in XR. Guess either A12 Bionic - iOS 15 pair is being too aggressive with the battery saving by handing over the light weight tasks prematurely to the efficiency cores or it's not transferring the data quick enough from efficiency to performance cores to avoid the frame drop. Either way, l really doubt that this will ever be rectified as it affects only one old model iPhone which is going to be noticed and raised to the forums by far fewer people like us. Not sure if this issue is present in 11, X, 8 or 7. Hence, the chances are slim!!

No. Not at all! I tried to cleanly reinstall the entire OS even via DFU mode which is the deepest possible installation known to us. Nothing ever changed. This is not a bug in firmware installation to get rid of. The problem is in the firmware itself. Issue is gonna be there until it is specifically fixed by Apple themselves which I feel is not happening anytime soon.

But I can give you one thing. Enable 'raise to wake' & disable 'follow focus' and disable 'live text' in the settings. Although it doesn't make the issue disappear, this has reduced the issue vastly IMO.

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.

Overall the UI is fairly smooth across the OS be it dark or light mode except for the swipe up gesture to go home or multi tasking in both modes from some apps especially Safari. I'm now testing the beta of next iOS in my XR. Will keep you guys posted on its progress. If I get to experience such lag or stutter in the way, I'll also report it to apple through the official feedback app for beta testers.

Something quite interesting happened to my iPhone today and don't know how to explain:

I was using my iPhone Xs in German language, and today I have changed it to my mother language, brazilian portuguese, and after this change all the hiccups and stuttering just stopped.

I'm using it for a couple of hours and so far everything is working perfectly.

I don't believe it's a placebo because I'm trying to stress it a lot to see any stuttering.

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.

Was reading a lot of chatter about this over on Reddit. Someone suggested turning off iCloud backups fixed all the lag with iOS 15 on the XR. I tried it and holy crap so far it’s day and night better. It’s only been an hour or so but everything I try is back to how it was performance wise before updating to iOS 15. Leave it to Apple to have one of their own services break their crap.

Everything seems fine, I left iCloud backups turned off for now. My phone now performs like it did before the upgrade. Turning off the backups just stops your phone from backing itself up to iCloud, it changes nothing else

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 an iPhone XS Max with iOS 15.1 and it has optimal battery health. Not to mention, this iPhone also has the A12 Bionic chip found inside the XR as well. I have noticed occasionally lag when swiping up on more intensive apps. (The animation where the app returns to the Home Screen will almost get stuck in the process for a brief moment). But once I try to replicate the lag a second time the animation will be as smooth as ever.

I personally think it could just be an software optimization issue or a problem with core optimization on the A12 Bionic chip. Whichever of the two I hope Apple addresses this soon.

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.
