- use matcap
- disable post process
- reduce resolution in settings
- flat color background
- no outline
- no wireframe
- opaque objects
- solo mode
All of the above will reduce gpu work.
I’ve never made some tests but I’m assuming the gpu is one of the culprit.
If you don’t interact with Nomad it shouldn’t use much battery (the ui and scene is not rendered), so not moving the camera aimlessly when you are doing nothing can help.

Obviously less polygons means less work for the cpu and gpu as well.
