Coming from a X, iOS 12 on the XS isn't nearly as fluid. I'm getting a lot of stuttering when closing apps and scrolling, specifically if I don't touch the display for 10 or so seconds and then swipe home. Is this anyone else's experience with the new phones?

How long have you had it running?
If its a new setup then the software could still be indexing in the background....

Got the phone Monday. I don’t think it’s indexing anymore at this point.

This was the main reason why I returned my Xs Max. My X is totally smooth so I just could not "upgrade" to a stuttering phone.

Having the same problem and you can find many thread on macrumors with the same problem.

Tried everything, only apple can solve this with a software update. They focused a bit too much on the older devices with ios 12.

My XS Max runs as good if not a hair faster than my X when doing side by side comparison. Definitely something is wrong

Huh, so you were having the same problem?
Yes, that stutter after about 10 seconds idle made reading news very annoying. Tried to read only from center of page and scroll more often to prevent stutter, did not work of course as it distracts too much from reading the article. :)

Mine was faster too but still stuttered.

To be fair, we shouldn't have to wait for an update to make Apple software run smoothly on a premium Apple device. It should be completely smooth from day one.
I wouldn't expect anything less TBH.
I have yet to set my XS Max up (coming from an X) and if mine is not smooth after a few days of use I will be returning mine too! I didn't pay this much for a stuttering device and having to wait an unknown length of time in the hope the next update will make it run as it should have from day one. Even then, an update wont guarantee a fix....

And IOS 12 should be performance update. In fact we all see IOS 12 is full of bugs just like it's still in beta. They fix one issue but make another. Remember when I updated From IOS 11.1.2 to 11.3.1 on my iPhone X and after unlocking phone you have to wait about 5 seconds for 3D touch to work. They fixed that in IOS 11.4 but it's not like it was before. I'm tired of this updates and testing and will stay on 11.4 which is optimized for iPhone X.

But the X runs better on iOS12 than 11.4?

To be fair iOS12 works wonderfully on my iPhone X.
Hope the same is true when I switch to my XS Max this evening....

Xs Max here. No issues with the stuttering. Smooth and quick. Have had phone 5 days now.
Did not set up as new, restored previous 6s Plus back-up.

Here’s what’s interesting- I’m not sure if it only impacts some devices or if some people just don’t notice it, but I tried to file a bug report and was going to use screen record and it would not stutter. Makes me believe there’s an optimization issue. Also, I tried to replicate this problem of four different XS and XS Max phones and couldn’t.

I’m giving it until 12.1 beta 2 or 12.0.1 to see if this is resolved before I return my XS and stick with my X.

Tried to show the stuttering when screen recording is running in the background and it doesnt stutter anymore (not looking at the video of the screen recording)

If no screen recorded in the background it stutters again

Which is what makes me believe iOS 12 needs better optimization for the newer phones. There’s some kind of throttling going on in the background.

Crazy because my old 6s runs like new on iOS 12.

So far all is running smoothly on my Xs Max with one exception. About half the time when I open the settings app it frees for about 15-20 seconds. I can’t scroll or select anything. After 15-20 seconds it works fine.

XS Max in UK, EE network, since my upgrade to this phone I am losing 4g indoors in places where it was fine on my 6S+
Anyone else in UK having indoor signal issues with the XS?

These stuttering that people are talking about are just small animation stutters where it drops from 60 FPS to 50 when opening an app. Which also only does it sometimes..
But yes.. all new things have bugs. That’s how software works.. iOS 12 had to be done by a certain day for them to be ready to go. They’ll release iOS 12.0.1 with bug fixes and improvements. This isn’t the first rodeo.. most of the time you have to look for bugs to see it. I didn’t even notice it until I started reading about in the forums.
