    How about setting a tasker profile to do this toggle for you. It can be based on triggers that are time based or also battery related.

    Does "simulating" monochrome consumes more battery than normal RGB ? Why I am asking this…I imagine "simulating" something means some extra calculations the CPU/GPU needs to do… that turns into more battery consumption.
