Phone heats up after the 26 update!!

it’s still heating up very quickly and draining my battery. Also got the latest iOS (iPhone 16) and latest game update. Have tried to reinstall the app. The in game settings are all on the lowest. I have noticed no difference on the gameplay though from high to low settings. I have tried to reset these and open and close the app a few times, it’s like the gameplay settings are not taking effect? My phone has plenty of space and all other apps are working fine and not draining the battery or overheating the phone. I have followed all other advice on the job. Anyone got any other suggestions? It was working fine before the fc 26 update. It’s not possible to now play the game for more than about 15 minutes at a time.
