Hello dude,[br]
Just had the EXACT same problem, solved it by opening the phone (2 screws to be removed next the charging port), disconnect the battery (just a small cable, it's easy af, many tutorials on youtube), plug the charger, reconnect the battery.
I read somewhere that it's due to a desync between the battery and the phone.
Good luck, I hope it'll be useful for someone ! I'm so happy to have repaired my phone <3
