Problem with quick recharge.

Hello everyone(sorry for my bad english)

i got a problem with my device, i noticed recently to slow recharge as original battery charger and as with a wireless charger battery ravpower; indeed the battery life go down in fast way.

When battery works good i can notice an overheating(when was in recharge), since it doesn't work this overheating is no longer present.

Wich test(app o pc software) i can use for test the battery first i send it on official samsung assistance.
