iPhone 7 P Wont charge when phone is sleeping
Had a iphone 7 plus come in for no power, replaced tristar and it powers now but wont charge when the phone is sleeping. Has a steady 1amp pull while booting to lock screen, the moment the screen goes black, power draw falls to 0. If i wake it power draw is around 0.3a.
Tried a second tristar, replaced tigris and q2101 next to it, new charge port and battery with no change.
Hoping someone has either seen this or can point me in the right direction what to check next.
