The battery may have degraded to be fair.
Each of those times you walked away, did you ever try plugging it in, counting to ten and then continuing to use it afterwards? That's what I used to do.
I use a trackpad now though.
ill give that a shot, thanks! im pretty sure it's just a dead battery though - after i charge it for 5-10 min it shows the percentage at like 3-5% which is enough for several more hours and then i just plug it in overnight
however i will say three years in, either a software update or hardware issue is now killing the battery and i have to charge it every week or two and that sucks
salty that i now have airpod pros, an iphone 13, and the magic keyboard and mouse all with their dumb lightning bolt or whatever it's called. going to have to rebuy all this to forever rid myself of non-usb-c cables but at least in 2024 it's finally happened as an option
