3D performance on mobile terrible LWRP. 60 draw calls and 12k tris

SetPass Calls: 48 Draw Calls: 63 Total Batches: 57 Tris: 11.3k Verts: 18.4k

These are what I'm getting from the unity profiler. I've tried the game on a Samsung Galaxy S6 so far and have abysmal performance. The fps never goes beyond 20 unless I look up a the skybox. I have trees in my scene which are supposed to be optimised for mobile and I also have a particle system that I use as a camp fire but have basically eliminated the fire system as the culprit as this point.

Is there something that I'm missing when it comes to mobile performance? I've tried both the LWRP with baked lighting, as well as the standard built in pipeline. I've only recently got back into this and was never a pro the last time I tried my hand at game development so I definitely could be doing something fundamentally wrong.? Is there settings I should be using? Thanks
