iPhone 11 Pro Performance problem - brutal lagging

[Nickelback21]

I have the iPhone 11 Pro Max 256 gig and it gets hot and lags. It’s playable but make sure your phone isn’t charging when playing. It’ll get too hot.

Same here - iPhone 11 Pro Max 256 GB. It seems you, CG, have a memory leak of sorts.  It starts fine and dandy but gets worse with every passing hour. Phone becomes hot and slows down to prevent overheating and ultimately failure.

Before reinstall I also had constant redownload of the last of 346 MBs. Maybe it has something to do with it.
