Okay.... Get ready for the "yes-but"......
Yes, but, remember when Apple said on stage years ago that they weren't about being the first to market, just the first to "do it right"?
I think we should all just trust Apple that 120hz refresh isn't there for a very good reason, of which one of them might be listed here (but perhaps another one):
1. Heat
2. battery
3. ridiculous cost that they would have to pass onto consumer
A question for thought, though: does anyone seriously think that Apple COULDN'T make 120 hz refresh happen? They have a good reason for it, and 60hz isn't terrible.
But, like you said, it does seem silly 120hz isn't there in a 2020 phone. Biiiiiiiiig shrug from me why Apple wouldn't put the 120hz in.... reviewers will certianly have something to say about that. 🤷♂️
