Home animation lagging in iphone xr ios 15

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.

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.

iOS 15.2.1 is a God sent update for XR users like us. This swipe based lag/stutter is reduced to a healthy 90% after updating to 15.2.1. Almost not happening in my iPhone XR nowadays. I was actually hopeless till 15.2. But now I'm very very hopefully that the next week update of 15.3 would iron out this issue completely and bring us the 14.8 level performance rightfully back to our XR devices. 🤞

15.2.1 has definitely improved the stutter by a lot, but I do get some stuttering still when swiping up during more intensive applications like, "air visual" and my browser "firefox" (when on a more intensive website). I'm hopeful iOS 15.2.2 or 15.3 will really improve these glitches even more.

On a side note I just reinstalled iOS to see what would happen and the stutters and animations when swiping up are definitely smother but there still is the occasional stutter as always. The Xs Max is a great phone and the Apple a12 chipset is still more powerful than the google Pixel 6s' Tensor chipset by comparison benchmarks. So there is no reason this can't be resolved in the near future if Apple's team is already at work on it.

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 😞

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.

I know this isn't related to iPhones or iOS, but I have a 12" Retina MacBook that stutters on webpages like twitter or YouTube. It shouldn't do that though seeing my much older 2011 MBP doesn't stutter. However I haven't found any sources besides you that have this issue. I just thought that was interesting that you brought that up.

Anyone else here have that issue on Mac OS Monterrey or iOS 15?

i have 2 Xs Max 512 and 64. 512 running fast zero problem while the 64 stuttering so annoying overall in every situation. both have sufficient storage. on 64 especially while working on keyboard and swipe up to home mostly will go to app switcher. same model with different feeling of transistion, scrolling, etc. weird

So far… just little improvements. Twitter, YouTube and occasionally the App Store… all still stuttering.

I read that frame drops is occurring a lot in games too… so maybe there’s something happening in iOS and this is affecting everything.

Different phone of mine to compare. Just for comparation. I used to have two Xs Max at the same time which is 512 and 64. Did reset for those 2 phones and updated to 15.3 use same wifi. While 512 run very well no stuttering at all, at the same time the other 64 stuttered like i used old iPhone. It was not about internal storage of course because for sure both are fresh. I don't think it was software related. If it was, all phones with related ios version should experiencing the same feel. And Apple will mention it on each update regarding that. I think perhaps hardware related. For example on SE 2016 there are 2 chipset manufacturer Samsung and TMSC that has different characteristics. Samsung is more powerful but hot. TMSC is below Samsung's performance but cooler. For my Xs Maxs case, i think maybe there are different parts on each phone that we don't know what it is that responsible for kind of lag and bit unresponsive touch here and there like on typing with keyboard, etc. Lucky phone will have good software on top of its certain hardware and unlucky phone vice versa

Another example: between two cars that exactly same type. One with grade A+ battery while the other A- grade of (same) battery installed. One with perfect tire and the other with "near perfect" tire. Something like that

Do you think that battery health may be a part of the problem? I checked my phones battery health in the normal battery tab in settings and it said "Peak Performance Capability" saying it was at 84% health. But when doing further research in settings it actually had about 600 battery cycles which is a lot for any iPhone. So I'm starting to think my problems may relate to that.

Mine XR battery health is 98%(In 2020, I replace a new battery by Apple Authorized Repair Center) Unfortunately, It still jitter when I done using Safari or Shopee APP and back to home... I miss iOS 13 so mach

I’m sorry but just to clarify, I don’t think the battery health indicator goes below 60 because then the battery becomes too difficult to accurately get a reading on. But I do get what you mean, if it’s not battery related it seems that it’s probably software unfortunately.

For me- I’m still getting my battery replaced if it drops any farther just because it’s old.
