I have been looking for my problem and it seems to be common among people who use kde, the battery icon shows that it is charging even if it is not connected.
I have used the upower command for more information on this in case it helps to solve the problem:

I can’t think of what to do from here, any help will be appreciated!
PS: I have tried installing upower-git from the AUR but nothing changed after reboot.
