Wireless Mouse & Battery Usage

Relitively simple question: I’ve recently configured a system where by I broadcast audio/video from my tv into my living room. I was pleased to find out that my logitech cordless mouse/keyboard are able to still receive their signal from the living room. What I was wondering is if their battery runs out faster if I’m using them from the next room versus using them right next to the computer?

Hope thats enough details, please don’t hesitate to ask for clarification, thanks.

The mouse and keyboard are unaware of the distance that separates them from the base, thus battery usage is a constant.

You might experience performance drop offs, but I think the battery usage is constant.
