Yes, I am so torn on this, too! I had trouble with the XS two years ago and had to trade it, and have been back on LCD models since. But I really want to get the mini for the size, and like the OP I was hopeful that the smaller screen = less sharp light and flicker blasting me in the face= less discomfort. But who really knows!
But I also am really interested in the Pro, for the extra features, higher specs, the 3rd lens, etc. A concern was not so much about cost, but more about the fact that it is a big screen- bigger than the XS was- so I was worried it would be bad for my eyes with the PWM flicker.
I got the 12 Pro. It doesn’t give me headaches but it makes my eyes water and I have had trouble focusing on print. It’s helped to switch to dark mode. And I absolutely can not have True Tone on.
This is the opposite case with my 11 Pro. I can’t use my 11 Pro on dark mode! Lol I don’t know what the hell is going on.
Still, the 12 Pro display isn’t nearly as difficult for me as the iPhone X display was. And there’s signs my eyes are gradually adjusting.
I haven’t gotten any headaches, but I have gotten fatigue and it makes me sleepy due to the eye strain.
I am returning my 12 Pro but not over the display issues. I feel over time my eyes will adjust or I will just use my Android phones more for things like ebooks and email and keep the Pro around to be in the ecosystem and keep up with iMessages. And use the great camera.
No, the killer for me is I can’t hold the device without really nasty hand pain. It’s just too heavy. Possibly too wide, too.
So I reluctantly am sending it back. I don’t know what I’ll do next. My 11 Pro also hurts my hands. The SE display causes a white flicker at the edge of my vision that happens after I’ve been using the phone for a few minutes.
I need iMessage while I still have kids in school. Even with them home schooling I’m getting frantic texts. It’s a stressful school year. In another few years I’ll just stop using smart phones. Maybe get the landline working again. I’m not aging well and it’s time to just let go.
