Iphone 6s suddenly stopped receiving charge. Loud speakers, headphone jack all stopped working as well. I factory reset and had the charging port and battery replaced, yet the problem is still there. What could be the problem? is it a motherboard issue? Thank you. Lun
Sounds like the Tristar charging chip and audio IC both blew at the same time. Have you checked inside the phone for signs of liquid damage?
