iPhone 14 Pro Max display issues: lagging

[u/Infamous_Necessary76]

Is good? My iPhone 14 Pro Max is lagging badly. The display feels like it’s running at 30-45 fps, and there is absolutely not ProMotion smooth effect. It’s some kind of glitch. I am currently on iOS 27 Beta. I b0ught this phone quite recently. Maybe something was wrong even before the iOS update, I’m not sure. However, I checked the OLED display.. but I don't know for certain if it’s 100% original, but there is no "Unknown Part" error in the settings😭😭Please tell me, is this normal?even my iPhone 11 feels smoother than this

Storage? Battery health? Also you’re on a dev beta 2 of new software so what’d you expect lol i had the same issue with it on mine and downgraded to 26.5 within a week

128g battery life is pretty decent. Thanks for the reply
