I ran an old game on my laptop testing running on battery and it quickly drained the battery down to 20%
but is it worth it when game only needs 1.5ghz P4,so save battery,lifespan or not?
or its the gpu that needs that takes most energy?
or screen brightness?
but if the outside has record 33+C it might be good to not run fullspeed?
if its a game that is of the old design to run as fast as possible,cpu will run fullspeed
