Check to make sure connectors are not bend etc. After that, check the charging port. Clean it of any debris etc, use a few puffs of air to clean it out. If none of this works, get a USB ammeter and see if your phone draws and amperage from the charger. if it does not it is possible that this is a charging port issue or a bad battery. Both can be repaired
