why do TV remotes get “weak” when the batteries start running low?

Question

I’d instinctively expect it to be more of a binary thing: they work, then when the batteries get to a certain level they completely stop working.

Instead you get this in between phase when the batteries start getting low, where you have to get closer to the TV for them to work. Why?

Answer 1

It is the taper of effect from batteries not being able to provide the necessary power. Unlike your tv where if you cut the power the tv instantly switches off the remote continues to receive power from the batteries but not enough to work properly. The same thing occurs with toys where as the batteries drain the sound becomes distorted and diabolical sounding.
