Sentry Crash Report:

Description The Feren OS Dev 2019-12-11 22:22:03 UTC 
SUMMARY
When running off a machine that is only powered by a plugged in power source (not a laptop or tablet) the Battery icon remains in the system tray as a redundant item in the tray by default.

STEPS TO REPRODUCE
1. Boot into Neon on a no-batteries machine
2. Check the System Tray

OBSERVED RESULT
There is a no batteries detected icon in there and its only use is toggling power management

EXPECTED RESULT
The icon would change to one of the following:
- Brightness icon if brightness can be changed still (Cinnamon)
- Power Symbol such as a lightning bolt if only toggling power management is available

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: KDE neon
(available in About System)
KDE Plasma Version: 5.17.4
KDE Frameworks Version: 5.64.0
Qt Version: 5.13.2

ADDITIONAL INFORMATION
Having a no batteries icon on a computer that is only powered by a plug is pointless and just feels out of place.
Comment 1 The Feren OS Dev 2019-12-11 22:24:08 UTC 
Slight bonus suggestion: Add an option in the Battery Plasmoid's settings to not hide the Plasmoid in the tray overflow menu when the battery is fully charged.

applets/batterymonitor: Improve for desktop systems

As it was so far, it looked like the system was malfunctioning because
we were showing a battery with a big fat red mark. If there's no battery
we can show the default icon.

As for the name, we only say "battery and brightness" when there's
both of them. Otherwise we show either title.

If neither batteries nor brightness are available, we mark the applet as
passive so people can at least still access the power management blocking
checkbox which lives here.
FIXED-IN: 5.24

The icon is no longer monochrome on Plasma 5.24 beta, it's green instead.
Is this intentional?
I'm using a desktop computer.

Hmm, that should have been fixed by https://invent.kde.org/plasma/plasma-workspace/-/commit/471cc3745b3a51a8b427fc1b44a22de228cbd945

Either way can you open a new bug report for it?
