The iPhone 13 Pro & Pro Max having PWM with a frequency response time around 480 Hz at 50% brightness and above is a big deal, because it means we're now making progress.
I want to stay in the ecosystem. Its a PITA that they know about it and have not produced an option since the IP11. So, I will hold out hope with my IPP 2018 and XR. Will possibly upgrade to a IP11 256 soon as stock on those are drying up locally.
Frequency isn't everything while Modulation also matters (according to IEEE standards 1789). Higher frequency can be even more risky if Modulation is high.

401 ppi LCD (vs 326 on the 11)
It seems like it absolutely could be the phone, but there are also several legitimate confounding variables. Maybe it’s good that you have two weeks, so that you can see if the bad is consistent daily or changes. Good luck!
It is still there, but 480Hz makes it a lot easier on the eyes.
I think that’s ultimately what I’m going to do as well. I’m still using the 13 pro and while wayyyy better than my previous experiences it’s still not as pleasant as my 11. But one thing I’ve found is I’m longing for the max. This regular pro feels small to me. I think I’ll give the max a go during the holiday return window.
This has been my experience too. My eyes are still irritated but I'm hoping that they'll get used to the new phone. They're not "sand paper gritty, wanna rip your eyeballs out" annoyed like they were with the 12 Pro though so I feel like the 13 Pro is definitely a step in the right direction. My eyes get super angery when things change though. It takes me at least a full month to get used to new glasses, even when there's nothing wrong with them. I'm going to keep using it until at least next weekend and then maybe decide. I'm cautiously optimistic that I'll be keeping it though. At least right now.
I'm one of those people who can't use the 11 or the Xr for that matter. I've tried every OLED iPhone. The 13 Pro Max, while not perfect, has been the most tolerable of all the previous OLED screens for me. I'm going to give it a week to see if it works out, but I'm not optimistic. I'll just go back to my trusty 8 Plus. To be honest, until I read this thread back in 2017 I never knew that I had an issue with OLED screens on phones. It's very frustrating! I've always upgraded my iPhones every two years since the original. But that ended in 2017. 🙁
@spillerz I really don’t know. A few people have mentioned temporal dithering being the reason. However, I use a 2020 iPad Pro without any problems.
Yeah, that’s weird. I haven’t heard people having problems with the 11..
Thanks for posting this. Disappointing to see that they’re going the wrong way 😐Frequency isn't everything while Modulation also matters (according to IEEE standards 1789). Higher frequency can be even more risky if Modulation is high.
Please see my replies below for details. TL; DR PWM is WORSE on iPhone 13 series than iPhone 12 Pro. It's not progress but downgrading due to LTPO display and of course the manufacturers' pursuit of display image quality rather than consumers' eye health (esp. in the long term)
iPhone 13 Pro: Screen PWM flicker at ALL brightness
Whoever says 480Hz PWM on iPhone 13 series is better/improved over 12 Pro is UTTERLY WRONG. The negative impact of low-freq PWM doesn't only correlate with the frequency but also (as pointed out above) with pulsation coefficient and modulation. iPhone 13 Pro/Max is terrible at both for ALL...
From my understanding of this issue, there are several factors in flicker sensitivity, and certain devices may trigger symptoms depending on a person’s individual threshold for flicker. The vast majority seem to have no issues whatsoever. A small minority seem to have issues with severe flicker (like with PWM). An even smaller minority have trouble with devices like the iPhone 11, iPad Pro, MacBook, etc depending on their sensitivity level.
