iPhone 17 Pro Constant stuttering and frame drops

[MothJab]

I have not seen much discussion on this yet, but I am experiencing constant frame dipping and stuttering on my new iPhone 17 Pro. It’s particularly bad when scrolling on white backgrounds such as Safari or Reddit, but also seems to happen when scrolling left to right on the home screens where there’s a widget.

I’m also seeing constant redraw of icons so like when you go into settings, it’ll take a half a second for them to start appearing.

Is anyone else having this issue?

Welcome to iOS26. I had the same choppy and laggy experience on a 17 Pro, on top of the WiFi/Bluetooth issues. Same on my 14 Plus that I sadly updated to iOS26, while my 13Pro has zero issues on iOS 18.7 😞.

No WiFi issues here but I use MLO network.

But yeah the stuttering is rough and it seems to get worst over time. If I do a restart, it briefly stops and then starts again.

I was considering doing a reset and setting up from new, but that is such a pain in the ass. And I’ve not seen anyone say it actually helps.

Yeah ProMotion is trash with iOS 26, it’s better capped at 60hz. Sucks we can’t downgrade the new iPhones.

Update: iOS 26.1 beta solves safari stuttering. BUT widget scrolling on the Home Screen still lags and so do other apps like reddit
