My game is lagging with no apparrent reasoning

I’m making my game for android and for some reason the game lags pretty bad on my decent phone (around 10-30 fps on an lgv30). One of the maps in the game is practically completely empty too and the fps doesn’t improve even slightly. I’ve tried all the techniques now. I’ve added occlusion culling, lowered render distance, lowered texture quality, turned off vsync, baked shadows, no shadows, and every other little quality setting you could think of. All of this caused little to no FPS increase at all. I’m completely lost now, so any help would be appreciated

Here is my profiler in the practically empty scene. Looks almost no different than the one on the full scene anyways
