Battery charging problem

You could also try to load the battery not in the phone, but with an external charger.
I got me this one , pretty cheap and does the job if needed.
It’s a generic China piece being sold under different brand names all over the internet.

… I think they sell universal external chargers (with adjustable contacts to fit different batteries) in shops all over the world, too. And buying locally takes care of power socket design and voltage.
