The mouse I use can charge wirelessly from a special mouse-pad. I’ve never had to think about batteries as a result. Pricey though. Combined the mouse / charging pad were close to $300 CAD
Using a mousepad at all is a nonstarter for me, and I avoid wireless charging generally because of the power waste that comes with it (I know, I'm weird).
Cords on my mouse and keyboard (aside from the one use case I mentioned) give me exactly no trouble anyway, so wireless stuff solves no problem I generally have.
That’s fair. For a keyboard I agree: mine has Bluetooth I’ve never used before. For a mouse though the lack of a cable is nice for playing FPSes and my work setup does double duty as my gaming setup.
