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?
In: 5
The remote control consists of three components, besides the battery:
* The buttons, which are electrical switches that can be on or off
* The microcontroller, which can either have enough power to work, or not
* The infrared-emitting LED, which sends signals to the TV
Of these, only one of them can get stronger or weaker, rather than just being OK or completely failing: the infrared LED. It will get weaker if the battery cannot provide enough power, which happens when the battery starts to run down. The other components will either work 100% or fail 100%; the infrared emitter is the only part that can “kinda-sorta” work.
