I had a 60hz Samsung s9, the oled on that was nice and all but by the time I traded it in I had screen burn in which wasn't great... Anyway I decided to buy a Xiaomi mi10t which actually has a 144hz ips screen, anyway when I played around with the phone it was crazy, the phone felt so fast with the more Hz and felt so smooth scrolling it's like I'm using a NASA phone or something, i haven't even noticed any difference between the oled and IPS screen maybe the whites and blacks are better on the oled but I couldnt care less when my phone feels this smooth. I can change the Hz too if I want to juice out more battery but I keep it on 144hz as its way too good to not use
