Why is the CPU usage so high?

As I mentioned in another question, I’m making a video game for android - but for some reason even though the RAM usage is now about 50mb, the CPU usage is still at almost 50%.
I would like to know ways which I can reduce the CPU usage

above is a picture of the average statistics of my game (draw calls goes up to 83 though) but apart from Tris and Verts every statistic looks really small - what could I have done to this project to make it so CPU intensive?

I don’t know what device your are testing on or what your game is about, but I can run way over 58 draw calls on my iPhone 4.

What you might want to consider are the Phyisic Calculations and PhysX that caused my CPU usage to go crazy.
