Hi,

thanks for the quick reply!

What exactly do you mean by "on battery"? When I am on AC, but the battery is 
plugged in, "acpi -b" prints
Battery 0: Unknown, 98%
After plugging AC off, it says
Battery 0: Discharging, 98%, 02:12:32 r
emaining
And when there is no battery it's empty.
As far as I can tell, it also does that when KDE displays the "no battery" 
icon, which is however hard to catch since it only lasts for a fraction of a 
second.

However, you gave me the idea to look for a CLI for upower, and there actually 
is one. "upower --monitor" prints this when plugging in AC:

[...]

So the problem is definitely within upower or even further down the stack, but 
not in KDE. I'll report a bug against upower.

Kind regards,
