I am unable to charge the phone

John flint, seems to be somewhat common. The charging port is soldered onto the logic board. Here is a good video on how to disassemble your phone. Then you will have to desolder the port from the logic board. Not an easy task since it has small contacts. You'll need some good skills and good equipment. the port is available at places like this. If you have never soldered on a logic board or if you do not have the tools, I would just have somebody do it for you. Not a complicated repair for somebody with experience. Hope this helps, good luck.
