Suitable statistics for mobile game?

I am experimenting and developing small open world game.
to have 80+ FPS, how should i optimize?
my game statistics:
static mesh tris 350k+
skeleton mesh tris 30k+(for 1player)
mesh draw call 800+
triangles drawn 650k+
in a viewport.
what other statistics should I look into?
and how to minimize it?
