iPhone 11 Lag

My IPhone 11 lags when playing pubg mobile...mostly in the last circles the game becomes unplayable with Frames ranging from 5-15fps...Any solution or i have to return the phone and buy oneplus instead..
Bro, which Settings you are playing on? Are you charging while playing? Do you youse Bluetooth headphones? Phone case mounted? I am sure it gets to warm or battery to low. I am playing PUBG mobile on iPhone 11 Pro Max on hdr/extreme without anti alansing and without shadows. Works like a charm....ping is always at 20ms here (sometimes it lags because charging while playing and the ping remains at 20ms - I turn on my blackshark fun cooler and it is okay again).
cheers
