People also seem to underestimate how complex resource management on a mobile OS is. That's not exactly an easy problem. Currently used apps scheduled background work currently active foreground services like the navigation app you are curently using, the image that is uploading in the background or the music that is playing .. stuff without a visible UI (except for a notification so you know what is going on). All important but not the main thing displayed right now. You also need to throttle the CPU when the phone runs too hot. But not run it at minimum speed either because it would make everything laggy. Also, if you pick up your phone out of your pocket, it automatically wakes up and increase CPU frequency because it is likely you are going to use it. Etc .. This is very complex problem, it is ok to let a machine balance this for us.
