My charging pin not working

@jogindarsah you are not telling us how you determined this issue is your charging port. At this time, with as little information as we have, my suggestion would be to replace the battery and the charging board which holds the charging port. Since iFixit does not yet have a specific guide for that, use something like this video to work on it. Also, do not forget to check the flex cable which goes from the charging board to the main board. Check for micro tears etc.

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 issues with their device. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
