I have a iphone 6s plus and it will not take a charge. If I use a new battery it works fine, but will not charge. I tried a new charge port and battery and newest update. I also tried many different apple charge cords. Nothing works. Any Ideals?

U2 Tristar charging IC needs to be replaced, only people that do micro-soldering can do it. Maybe you can find a Mobile Phone repair shop near you that offers this service.
