Won't Work Unless Plugged In

[romulus]

My pinephone gets stuck in a sort of loop of having me enter my password, then the screen flashes a few times and kicks me back to the lockscreen. It only does this while not receiving power. If it is plugged in and getting power everything works fine. If it is plugged in while I am using it then I unplug it, it turns off. The battery percentage also moves around quite a bit. It changes by a few percent more right when I unplug, then shows over 10 percent more when unplugged and on lockscreen. It is completely up to date as of today, running Manjaro with KDE Plasma. 
Any and all help is appreciated

Can't confirm here.
At some stage of development, the Setup->Screen application wrote incorrect values to /.config/powermanagementprofilesrc file. There are several posts with solutions here so do a search
Or flash a fresh image - that bug has been fixed.
