Yes, I've been experiencing the same issue too on my iPhone 14 Pro Max. Still going after iOS 16.1. Did a full back up and reinstall and still the issue persists. Switching back to Android until Apple finally sorts this shambles out.Running iOS 16.0.2 on iPhone 14 Pro Max (512G).
When I open an application (random) and use it for a while, there will be a lag when I swipe up and close it. If I immediately reopen the same application and close it, the same problem will not occur. This doesn't happen every time, but from time to time.
Restarting the phone fixed the issue briefly, but it would come back after one day.
