If the phone is completely dead, locate the battery connector on the schematic. Measure the voltage on the main power line (often labeled VPH_PWR or VBAT ). It should register between 3.7V and 4.2V. If this line reads 0V or shows a direct short to ground, you have a primary short circuit. Step 2: Inspect PMIC Outputs (Buck & LDO Regulators)
Always match the voltage values listed in the service manual test points with your multimeter readings. Redmi Note 10 Pro Schematic Diagram Pdf Free Download
