Hey, all, This morning I replaced the power port/ Headphone jack on my iPhone 6s Plus but since then I can only charge the phone with one side of the cable. Strange, really strange as the pins are the same side in the phone and I have tried multiple chargers. It’s not that big of a deal as it actually charges now vs before I replaced but I would like to fix it. Thank you in advance.
Faulty charging port. If you got it from ifixit contact them for a replacement.
