Diode mode on gate of Q7055 0.641 original Apple 60 W charger Bad battery seems like, the one in the macbook has 794 cycles, tried with a 2 cycles one and it shows 1h10 min to charge from 47% Thanks Duke

Hi, I have a 820 2936 mb that charges very slowly. Already changed Q7055 with a known good one but no change, same thing with U 7000. U7000 area look good no water damage. Any idea where to look next? Battery at 95 % and the estimated time of full charge is 35minutes. Thanks

Ok, thanks Duke...

So, based on Louis ideea I've checked resistance over C7050 and everything was ok, then I've measured R7021 and got 175K so I replaced it then R7022 showed me 4.10Mohms, at this point I assumed the U7000 is broken so I replaced it an now I have a good 8.4 V on PPBUS_G3H, PP3V42_G3H is stable at...
