iPhone 6 USB and U2 been changed but still not charging - GSM-Forum

VeeFTeeS · 01-30-2016, 22:38

Hi guys,

I have a problem with my iPhone 6 after a minor water damage. All looks working fine except charging. It shows charging but percentage not incrasing.
I have already changed the USB flex and U2 IC but fault remains.
Does anyone have idea what can be next?
Thanks in advance!

Reball or change u2 again.

Thanks for answer.
Do you think the new U2 is faulty as well? In this case I have to contact to ebay seller because I ordered from there.

iphone 6 no charging, check U1401 (charing IC) and Q1403

I have changed U2 second time. Still fake charging. :/ Does Q1403 controls charger or just switching? Does anybody have a schematic? I read in other thread (can't put a link) about L1401 do you know where it is on the board? Or is it in the charger circuit?

Unfortunately I've done a mistake. My tweezers slided under the shield accidentally and pushed the antenna switch ic up. So now I have a big mess between the lte ic and antenna switch ic (right-bottom corner). Can somebody please put a photo of that area at least I can see where I have to put the capacolitors and where the coils.
I can see on this photo but I think not all of them mounted on the board.
