I’m a student.iPhone 15 is my first iPhone and I bought it for its smoothness and fast but unfortunately I have been encountering several lags and screen shuttering and glitches whenever I unlock the phone ,swipe between home screens and closing apps. The becomes heat when I shoot photos and after that the phone become very laggy for few minutes . After updating to iOS 17.5 I got this problem and it still continues to iOS 18.0.1. Finally the iOS experience is very poor to me and my friend’s old iPhone XS doesn’t have these type of problems. Apple please fix this problem.

There is no Apple here in these user to user technical forums.

Basic troubleshooting:

Restart, Reset, Restore from backup and Restore as NEW.

I tried them but it didn’t work

You already restore your phone as NEW and not from backup?
