Android 2D platformer, low fps

Hi,
I am trying to make rogulike 2D pixel art platformer for android.
But i am struggling with optimization. I am trying to get on stable 60fps, but for some reasons, on most phones, i have low fps (about 20-40). I am using tilemaps and universal render pipeline with their experimental 2D renderer. With tilemaps on, I am getting on Nokia 8 about 60fps, but on phones like Samsung galaxy J5 or Huawei P9 lite 2017 its about 20-40 fps. And with tilemaps off i am getting at least 55fps on every single one of these phones. I have no idea what to do to get at least 50fps with tilemaps.
