Hello

iPhone 6s charging well, but when the device turn on charging stoped and dont recognize the pc.
I changed:
Tristar twice
U2300
C2300
Jumper on Q4500
Try with other battery and dock flex.

Any idea?
Thanks

This symptom refers to Tristar fault, because it's high speed switcher.

I think you need to remove it and check all rails between CPU PMIC & other.
