Schematic and block diagram for the Xiaomi Redmi 3, with code 88509 and 1.27 in the name, probably a document number and revision. It is listed as firmware but contains circuit documentation by name. The block diagram shows how the main subsystems connect, and the detailed pages help trace power rails, charging, USB and display lines during fault finding on a dead or shorted phone. Check that your board version matches revision markings on the drawings before relying on exact part values.
