The charging management IC measures this rail to verify the integrity of the physical connection.

Poor quality chargers can send erratic voltage surges, killing the USB control IC or damaging the line. 5. Conclusion This link or copies made by others cannot be deleted

PP_VAR_USB_RVP refers to a specific power rail or "line" found in the charging circuitry of modern (specifically iPhone 11 and newer models). It stands for Power Positive Variable USB Reverse Voltage Protection 📱 Function and Circuitry

Due to the sheer volume of low-quality aftermarket chargers on the market, the inline resistor on the line takes a massive beating. Sudden spikes blow the resistor open.

Remove the shorted capacitor. Often, the phone will turn on without it (though it is best practice to replace it for long-term stability).
