Just to post an update and close this thread I will explain how I found what’s wrong with the motherboard… The problem was with the bad solder on Zener diode D7012, and I found this by measuring the voltage on the capacitor C7012 - on pad 1 of the capacitor I was getting around 15V (voltage from the MagSafe) but on the pad 2 of the capacitor I was getting around 14V which is not good. The voltage on pad 2 of C7012 needs to be around 6.8V because of the Zener diode (GDZT2R6.8) that pulls down the voltage. This voltage drop is needed in order for Q7010 to open and send the same voltage on pin 1 (6.8V). Since I was not getting the right voltages I checked the diode under the microscope and found that one pad was not soldered correctly. I also replaced the diode with another one, but since I didn’t have the MacBook donor board I used the diode from the iPhone 5S motherboard :) It is the same diode but the one from the iPhone board is rated at 6.2V instead of 6.8V, but anyway it works :) This diode is placed...

Can I use 610A3B for iphone 8?

I have the same issue, only that my iPhone 6S is taking 0.02A before prompt to boot. The phone is working fine, the only problem is that it discharges the battery overnight, even when the phone is off. The battery is new. I checked all capacitors on that line and none of them is shorted. In diode mode, all capacitor readings are around 0.910V. I replaced the Tigris and MOSFET from the donor board (I tested the board before taking these 2 IC’s so it’s a known good donor board) but there is still 0.02A draw on PP_BAT_VCC line. Any ideas?

At this time I know for sure that I have good PMIC on board but phone still doesn't boot up. Any suggestions on what to check? I checked all capacitors arround PMIC and all are good (compared to my icloud locked board).

I'v had this problem with iPhone 6 (ghosted loudspeaker button) and replacing the AUDIO (codec) IC solved it.
