iPhone SE fake charging


Hey guys,
I have an iphone SE here that is fake charging. I've already replaced tristar (u2) ic but same result.
It would pull 1.15A during boot and then it would drop to about 0.01-0.20.
Just not charging.
Any ideas?

Hello

Check R4640 (1Kohm) replace if necessary.
Check the voltage on C4503 (5V), if missing remove Q4500 and make jumper on PIN3 to PIN2.

Hi,

I've problem with SE.
It's stuck at 5% charge, won't charge above 5%, seems fake charging.
Someone tried to replace the screen before I received this iphone.

I think that in my case C4503 is short.
Is there any alternative replacement I could use? I don't want to remove C4500, I'd prefer to replace C4503 with another capacitor.

I've some iphone 6, 5s motherboards so could use them as a donors.

Anybody can point me which alternatve capacitor I could use to fit C4503 ?

Many Thanks in advance.

I'm sorry for another post but I've noticed FL2400 and C2400 missing near the battery connector, so soldered new one but the same, iphone se stuck at 5% and won't charge more than that. I also replaced usb flex and the same.
I reflow Q2, 1 fuse near the usb connector was loose so I soldered it back on.

Any more ideas what that could be? What else could I try? Tristar is ok.
