How to find issue of slow charging and fast discharging?
Hello! I just bought used, damaged iPhone 6s.
First I replaced battery for branded Apple - and phone wake up.
Next, I replaced flex cable with charging port and jack, because jack was not working - now it works.
Now everything is good except… very slow charging, and fast discharging. I’m using good quality Mcdodo cable, tried with every possible chargers and also other cables.
Can you tell me what could be faulty? Best advice would be, what should I measure to localize the issue. Any iPhone schematics source? Can it be just Tristar power management chip?
Please help :)
