Possible to reduce CPU usage for static UI?

Noob here investigating Bevy.

I'm toying with the idea of getting bevy to run on android. But the examples use a pretty considerable amount of CPU even when doing nothing. I assume its rendering X times a second no matter what. That's great for a game where objects move and etc and the view needs to be constantly updated. But for a more static UI its a waste of CPU, not good for a battery powered device.

Are there any alternative approaches that might be more event driven for rendering? Or is that still just in the planning stage right now.

This example should have everything you need to make bevy only render on user input https://bevy.org/examples/window/low-power/
