I too have this problem in KDE Neon, however I tried Wayland to see how things have improved and the battery indicator was there.

Battery monitor has nothing do with the other system monitor plasmoids

Comment 5 Sam 2020-06-10 18:34:14 UTC

Facing same issue on kde neon after latest updates. 

using 'kquitapp5 plasmashell && kstart5 plasmashell' I get my icon back till next reboot.

Cannot reproduce, but we are getting multiple reports of this.

Comment 7 Petr Bartos 2020-06-10 20:05:28 UTC

Hi,
I've same problem on Fedora. I've found out that if I change visibility of any other tray icon in tray setting, battery indicator appears.

Comment 8 Eric Donkersloot 2020-06-10 20:35:41 UTC

Ignore my comment #3 that seems to be related to a different bug and I erroneously placed it here. My bad.

Comment 9 Eric Donkersloot 2020-06-10 21:08:35 UTC

The workaround Petr is suggesting in comment #7 doesn't work for me.

Comment 10 Jack Todaro 2020-06-10 21:29:43 UTC

Enabling the weather widget in the system tray (rather than as a separate widget) resulted in the battery and brightness widget showing up - but it stated 'no batteries available'. Manually querying the battery with upower showed that the battery is indeed detected, and its charge and other statistics correctly displayed.

When my laptop hit critical battery, I did get a plasma notification about it. But the battery and brightness widget remained hidden from view.

I'm on Gentoo Linux with the same OS type, KDE, Qt and Linux kernel versions as the OP.

Comment 11 Jack Todaro 2020-06-10 21:46:49 UTC

I should add that contrary to Sam Dyer's experience in comment #1, this only occurs for me in the Wayland session. The battery indicator is functional and visible in the X11 session.

Comment 12 Sam 2020-06-11 08:41:07 UTC

For me wayland session it is showing, but not in standard plasma session.
restarting plasma shell gets icon back.

Comment 13 David Edmundson 2020-06-11 10:21:58 UTC

Reproduced, attached gammaray and have a relevant data point.

SystemTrayModel  has an entry "Battery and Brightness" but hasApplet is false.
