Hi, I have replaced tristar two time but having same problem. iphone 6s is not charging above 4%. But it is charging when i turn it off and also not detecting lighting cable when on. but booting with plug in the charging cable. Please provide some solution and what is this problem?
Have you tried the simple stuff such as trying another charging port / battery? The ohm of resistance measurement value will depending on what components are between the circuit from red probe point to black probe point. Each capacitor / resistor or other SMD components directly on that line will increase the resistance on that circuit. The schematic will tell you how much ohms some components are so you can add them up to match your measurements.
