my phone is not charging even when i am using the new battery and how to resolve it.. i think the charging port is damaged and please help me is repairing that…..kindly send me the repairing formats …..

@logesam the USB port is soldered to the logic board.

To remove it you will have to disassemble your phone. Use this document Samsung-GT-S7562.pdf to disassemble your phone. After that you will have to unsolder the port, find a replacement and then resolder the new port.

Hi Logesam, I apologize for not being too familiar with that device in particular. It appears to be very similar to the Galaxy S3 though. When you open it up is the charging port soldered on the main board, or is it a separate component attached by a ribbon cable? If it is truly similar to the S3, it may be easier to repair than you think.
