MX Keys battery % incorrect if charging when turned on, and typing input lags
My MX Keys keyboard reports that it is 0% battery (despite being 100%) when I turn it on if it is plugged in and charging at the time. If I unplug it, though, it will quickly update to show as having 100% battery. If I plug it back in after that, it correctly still shows 100% battery.
I think that this contributes to a very annoying issue where the keyboard input "lags" very badly when typing. I think this could be related to the computer thinking that the keyboard is low on battery, so it tries to save battery by reducing power consumption or something?
I have this issue on my company-issued Dell Latitude 7290 running latest Windows 10, but not on my personal computer (MSI laptop).
