I use Plasma on my PinePhone Pro with the Pine keyboard (that includes additional battery).
Powerdevil detects that the phone is charging, while it actually not.
Sysfs reports that both batteries discharging:
```
shatur@pinephone-pro ~> cat /sys/class/power_supply/rk818-battery/status
Discharging
shatur@pinephone-pro ~> cat /sys/class/power_supply/ip5xxx-battery/status
Discharging
```

Here is the output from `upower -d`: https://pastebin.com/YaiQGqAx
Everything is discharging.

But powerdevil thinks that the phone is charging for some reason. I would expect it to detect charging only when at least one battery is charging.
