What do you thing could be wrong with your iPhone not charging even after battery and charging port replacement the next component in the line is charging ic which also known as u2 charging ic or tristar charging ic part number 1610a2. Replacing charging ic is very skilled job. This is one of the smaller ic / part on iPhone logic board. Other than iPhone not charging even after battery and charging port replacement are also fake charging where iPhone will show different percentage of iPhone charged and dropped quickly within minutes and iPhone will turns off. One of other faulty iPhone u2 charging ic is very slow charging and then battery drains quickly.
We have seen unskilled technicians try to heat u2 ic thinking this might fix the problem but this will make it even worse. iPhone u2 charging ic is underfill ic so don’t try to heat it as the solder joints / balls on underfill ic with heat will explode and will damage the lines. See in the above picture we have taking the iPhone charging ic and clean the surface area and the pads on the logic board are exposed and shinny and ready to take new charging ic.
If you are bit familiar with ic replacement on iPhones specially one of the tiniest on iPhone logic board like this u2 ic you will appreciate the high level of skilled work you see in the above picture. No mess around the work and a clean pull and board is ready to adapt new ic.
