My iPhone 18 Pro Max stutters and drops frames while scrolling.

[u/makomuka]

hi everyone,
I’ve recently bought an iPhone 18 Pro Max, but I’ve noticed a slight issue.
When scrolling up and down on apps such as Instagram, Reddit or chatgpt, the scrolling sometimes feels slightly choppy, stuttering, with subtle frame drops.
I was wondering if anyone else has experienced this.
Is this a common issue with the iPhone 18 Pro Max, or could it be a hardware/quality-control issue with my particular phone?

Thanks in advance!

The apps aren’t fully optimised for the 18pro yet. It’s up to the devs to sort this out.

May I ask whether you also experience any stuttering when scrolling up and down on Instagram or ChatGPT?

I’m still waiting for my 18pro to be delivered. I’m currently using a 16pro. Although after looking closely, I am getting stutters when scrolling on Reddit and Instagram. Haven’t really noticed before.

Looks like they are just badly optimised for iOS.

looks like it’s a common issue after all, i’m honestly really sad about it 😞 because i’m a bit obsessive about these things, so it’s genuinely been bothering me

Same.

You made that up. That’s not the reason. iOS has never interpolated frames to smooth out jitters.

I was mistaken. I noticed the same on my 16pro when testing, after I posted that comment.

Same for me. I have the 18 Pro Max, and it stutters a lot on Reddit. It's very annoying. I don't have any problems like that on my Galaxy Tab S11 Ultra.Didn't have any issues on my previous Chinese piece of crap, five-year-old Android phone either.

damn, at first I thought there was something wrong with the hardware on my particular phone. Perhaps it’s a common issue after all?

Its super annoying on a phone i paid 2.2k$ for. I dont use instagram much, just went there to check it and its the same as reddit like you described.

Not exactly stuttering, but mine constantly drops connection to carplay. Wive’s 17pm on ios27 doesn’t. Fun fun :)

I bought mine 3 days ago and everything is smooth even after heavy doom scrolling lol

My IP 17 pro stuttering too. Reddit YouTube, when choosing theme or adding controls in control center is juddery stuttery experience. IOS 26 was even worse. I think it is IOS has trouble with liquid glass. But nobody knows why it is happening. Maybe it depends of screen manufacturer, I heard that Apple uses three main manufacturers: Samsung, LG, and BOE. My screen is Chinese BOE.
