Has anyone noticed a slight stutter when closing apps on iPhone 7?

With my 6S on iOS 10, the closing animation was smooth and fast. I've noticed on my 7 that when I close an app, there is a slight stutter in the middle of the animation. Just wondering if it's just my phone or if others noticed. Thanks!

yes i have the same issue. same when going from an app into Multitasking. hope they will bring an update soon :/
 
I noticed it as well. I compared it to a iPhone 6 Plus and it definitely stutters. The iPhone 6 Plus takes much longer to close apps though, but the animation is smoother. If you go back into the app right away and close it again, is it smoother? It is on mine. Only for short period of time. I was starting to wonder if it was the backup I used to restore the phone. I am tempted to restore the phone to factory defaults and see if it does it. Thats a PITA though.
 
first i set the phone without a backup. stutters appears. after i "backupded" my iPhone its still stutter :/
must be a Software issue together with the darker Display...
 
Yeah it seems like it doesn't recognize the input for a half second or so while quickly swiping up to close apps. I'm on a 6S Plus with iOS 10 too.
 
I believe it may be this way by design. You may have never noticed, but on every iPhone there's always been a slight delay upon clicking the home button once. That's because the phone is waiting to see if you'll click it a second time to initiate multitasking. It looks like since iOS 10, has Apple tried to eliminate the apparentness of this delay in a couple of ways. The first is that, if you click the home button while an app is animating open from the home screen, it won't wait for a second click and will immediately close the app — it all feels very snappy. But one thing unique to the 7 is that, while in an app, instead of waiting for a potential second click after clicking once, it does a slight animation where the app in view "shrinks" inward a bit. If you don't click a second time, it speeds up and closes the app all the way to the home screen. If you click a second time, it then enters multitasking — all together, this animation looks like the app is shaking a bit as the whole device clicks when double clicking the home button, which is neat. But I agree it looks a little buggy while going to the home screen.


TL;DR it seems intentional, I can see them getting rid of it in an update, and I need to learn how to be concise 🙂

Yes I've also experienced this app exit animation stutter, and as an OCD user who paid so much for a device I expect animations to be perfect on day 1. Issue persists even after updating to 10.0.1, it's unacceptable. You'd think Apple engineers would fully test the phone on iOS before giving a thumbs up to ship the product. Very disappointed at this botched launch.

It kinda bugs me too so I went into Accessability options and enabled the Reduced motion option which completely eliminates any lag as it changes how apps close. Only temporarily until I see a new software update and I'll test it for a fix to this
 
Here is my thought: that animation may be fairly processor intensive... but remember that the iPhone 7 runs on the 2 puny underclocked cores most of the time.

It could be that those cores aren't up to the task of that animation... but the fast cores don't spin up fast enough to make the animation smooth (and / or the stutter you see is the fast cores taking over).

This idea also explains some of the above statements about how it will be smooth for a little while afterward. Most likely the fast cores are spinning up to finish the animation... and they remain active for a period of time before shutting down again and handing off to the slow cores to save power. During that time everything will be fast and smooth.

This is Apple's first attempt at such a setup in a mobile device... so it may take a bit before they figure out the right way to integrate the software with the hardware.
