Bug 361708

screenshot of the problem

Same exact issue - on Neon Xenial running Plasma 5.13. `acpi` and `upower` will show the battery charge/discharge status correctly responding to AC plug on/off events, but the plasmashell battery icon will remain on "plugged in" mode even if I unplug.

Strangely, sometimes the battery icon will still say "plugged in," even though when I click on the battery, it still says "discharging". Screenshot attached below.

Battery inconsistency

Note the tray icon still has the battery in AC mode, even though it is listed as "Discharging" in the panel.

More importantly, the power management settings still respond as if the AC were plugged in. I want it to auto-suspend only if battery is discharging and not suspend if AC is plugged in. The result here is that it thinks the AC is plugged in, discharges, and drains the battery.

All charging

One more - now things are plugged in. Note that the tray icon is "charging", and now the battery icon in the panel dropdown is also "charging." In the previous screenshot, the battery icon in the panel dropdown was the normal "discharging" battery.

However, crucially, in both cases, the battery tray icon was charging -- even though it is only really charging in this one and not the last one. The tray icon seems to dictate which power management behaviors are followed, so that it always does AC mode even if discharging.

Finally, I note the problem may result from a discrepancy between upower and acpi. Note the following terminal results. Both of these are in the state where the AC is not plugged in, but the tray icon still says discharging (even though battery panel icon says discharging):

Sorry if there is a better place to report this but cold not find any more recent bug report on this issue.

Sometimes my battery indicator in sys tray still says "plugged in" (and the icon has the power plug in it) even though I have unplugged the power adaptor . 
When hovering the mouse over it, it says "Plugged in but still discharging".
When clicking on it, the indicator says, "discharging", and the battery icon inside the popup window is the correct one (i.e. without the power plug in it).

See screenshot attached.

The issue is that he system does not go to sleep any more.

For info, I have rule to stop charging at 85% and start at 45%.

I "think" the issue happens after a wake up from sleep but I'm not sure and it is a bit random.

Plugging back the power adaptor and unplugging it does not solve the issue. The only thing that seem to solve it is rebooting (then it works fine). 

I saw the issue being reported here too:

- https://forum.manjaro.org/t/battery-icon-is-constantly-in-charging-mode/27605
- https://bbs.archlinux.org/viewtopic.php?id=236409 (in  here it says it is a bug in upower, but I cannot test that as I cannot downgrade to the version proposed in the article - I run upower version 0.99.11)
