Schematic archive for the Xiaomi Redmi 3S smartphone, with the code 88537 and 1.20 in the name, likely a document number and revision. Although listed under firmware, the file name indicates circuit diagrams. Use them to follow power rails from the PMIC, check battery and USB charging paths, and trace signals to connectors when diagnosing no power, no charge or display faults. Compare the board revision and component references on your phone with the drawings, since later production runs can differ.
