FPS drops from 60 to 15 after 3 minutes of playing?

Question

Unity

In general, I’m making a game for Android, I did a lot of things with optimization, but when I launch the finished apk on the phone, at first everything is fine 60 fps is stable and after 3 minutes the fps drops to 15. How to solve?
