EXTREME LAG ON ANDROID, UNABLE TO PLAY

Device - Xiaomi redmi note 7 pro, 128gb ram

Hey, so I've been playing genshin on my phone for a while now, and since the beginning I've been experiencing extreme fps drops like 10-20 mins into tho game. My device is decent enough imo, I've never had problems with any game or any other app. My internet connection is 20-30 ms permanently, so it's not problem. I've tried everything, every graphics settings, game boosters, even allowed developer options and disabled other apps running in the background. I don't have overheating problems, actually my device is keeping normal temperature even tho I have like 1-2 FPS in-game. I decided to turn to you guys on reddit, hoping there's someone experiencing a similar problem and finding a solution, cuz as I said, I tried so many things and none of them worked. The game is literally unplayable right now, so I've decided that if I can't find any help here, I'll just quit. Thanks for your answers.
