Layered Power Management

Back in the day when batteries in remote controls ran low, they would be working one moment and not the next, right?

Apparently though, based on how different remotes are designed and how power is distributed, different buttons and functions are affected differently when power starts running low.

I noticed this over the weekend when the batts on the Fire TV remote were low. Volume and power buttons stopped working. However, I could still select movies, rewind and forward, and move back to the main menu.

A logically layered power management plan would be a good thing to have on gadgets and remotes, so that even in the absence of an power indicator, one becomes aware of low power and can still use essential (or important) functions on it for a while before the batteries completely die out.

Like when you are on 7% power on the arc reactor and in a mid-air combat with a much stronger Iron Monger (in Ironman 1).
Or are watching a movie over the weekend and are a bit lazy to get up to change batteries on the remote just to be able to pause or change the volume.
