@mike It’s really a daft design, I mean, the rechargeable “Magic” keyboard becomes a wired keyboard & the BT is shut off when the charge cable is connected. I just cannot see why the mouse couldn’t employ the same functionality. I use a Logitech M558 BT mouse that’s designed to last at least a year on a pair of alkaline batteries. @phocks
