Battery showing no charge when not plugged in but 100% charged when plugged in

My video doorbell hasn’t worked in some time. It is showing as 0% battery (and doesn’t work at all) when it isn’t plugged into the UBS charger, however, when I plug it into the charger it shows as 100% and detects motion, any suggestions?

Hey @westxxax. Have you tried charging it up for the time it needs to be charged (after 8 hours) to see if it works after a full time’s charge?
