iPhone 11 Pro Overheats & Lags After iOS 18 Update

After updating to iOS 18, my iPhone 11 Pro has become unbearably slow and overheats frequently. The worst part is the keyboard lag—typing has become frustrating because the phone freezes mid-use. Before this update, my phone worked perfectly fine, but now, even basic tasks feel sluggish.

Apple, you need to fix this immediately. I expect software updates to improve performance, not make my device worse. I don’t want to be forced into buying a new phone because of an update that clearly wasn’t optimized for older models. When will we get a proper update to fix these issues? This is unacceptable!
