Anyone ever replace the battery connector (not usb port)?

So it would appear that the battery connect that the battery actually touches, not the usb port, is damaged and charges my phone extremely slow because of the bad contact. I've tried adjusting the spring type prongs on it to no avail. Have any of you guys ever replaced one of these or know someone who has? It is similar to replacing the connectors on the older iPhones? I just bought a Note 5 and am keeping this phone as a backup, so I need to have it working properly, I don't want to have to buy an external charger.

Thanks guys,

Jeff
