Game draining battery


My game is draining too much battery. It sucks almost 5-6percent battery in a 5 minute gameplay session. I am making the game for PC. Please help me.
I tried everything, disabled the vSync. converted all my text to text mesh pro. forced the target framerate to 40. But nothing helped.
Here is the screenshot of my profiler.

Thanks a lot

The plugins that I am using are Puppet2D and text mesh pro.
