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.

On a conventional TV remote, when you press a button, you’re just completing a circuit for something that controls a non-visible light at the end of the remote. In the same way that a flashlight will get dim as its batteries die, the light on the remote won’t be as strong when the batteries start to go for it. As the light gets weaker, the TV can’t necessarily see it as easily.
