My Charging port malfunction

@dawitshemsu your charging port is soldered to your motherboard. You will need to remove that. Since iFixit does not yet have a guide for this, use the one from here Now, you have to desolder the old port and solder a new port on. Replacement ports are available at places like this and many others. Check something like this video to check the whole repair.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
