My S10 will only charge when it is plugged into a power outlet attached to the charging "brick". It no longer will charge in my car or on a portable charger. I even switched out the chargers and cords and no luck.
Go it. So this is not the solution but better, clean your charging port and get a mi power bank they are cheap and had fast charging. I have kinda same issue so I use my wall charger or power bank. For me it will show normal charging even tho I connect my mobile to a fast charging
