Check the voltage or diode drop on the capacitor closest to the USB Control IC (e.g., C6312 in iPhone XR, or C9610 in iPhone 14 Pro Max).

This line is located on the motherboard and is part of the circuit connecting the charging flex cable dock to the main charging ICs.

The voltage moves to the motherboard through the PP_VAR_USB_RVP line. pp-var-usb-rvp

Carrying the incoming 5V charge from the USB port to the charging dock area.

If you measure 0V on this rail while a live, official 5V charger is connected, look closely at the control signals enabling the protection gates. For instance, checking relevant enable test points like PWR_GATE_EN_VBUS_1_VALID will confirm whether the device's USB controller chip is actively commanding the safety gates to open. If the enable signals are missing, the fault lies within the logic of the USB IC rather than a physical short circuit. Summary for Micro-Soldering Technicians
