Hello! Scaling down or using a power_save_governor sounds like "energy saving" but in practive this is often not the case. If you slow down your processor, it will take more time to fullfill it tasks and therefore more time until it can go into a deep sleep state.
There are better ways to save energy:
Reduce display brigthness, turn off bluetooth or wifi, avoid using GPS and prefer cell-tower based services for location, turn off Android-Support...

A well known example is the p_state driver from Intel, basically it let the processor decide upon the tasks pending, the power consumption and used cores how much voltage and clockspeed it wants. It aim is it, to finish the work as fast as possible without wasting to much energy and then go to sleep and stay there as long as possible.
