iPhone 6 multimeter keeps changing?
I'm testing the charging port as my phone has a the fake charging issue and gets very hot. I've tested the pin on the battery terminal to the metal piece on the SIM card holder with a multimeter, apparently the voltage should be between 1.8 and 4.2 V but mine goes from 3.8 volts and jumps down to 0.3 and up again with the battery disconnected and the charging cable in. This continuously jumps from 0.3 to 3.8 so I'm wondering if I need to replace the charging port, I've disconnected the charging port flex from the loudspeaker while the phone is on but the same issue occurs and will just continue to get hot and lose battery fast.
