So if an iphone 7 is dead it's not the classic Tristar? It's the U2101 now ? I have an iPhone 7 reballed the Tristar and nothing. I will check the Tigris now

Iphone 7 charging only when is powered off

Hi i would ask if someone have any experience with IPHONE 7 that charges only when powered off.
Firstly this have U4001 completed dead and in short (found with freeze )
Now the phone charge perfectly but when APPle logo is shown phone stop charging.
We replaced U2101 and bypassed Q201 but always same thing.

Maybe someone has any experience

Thanks in advance
