Repairers use such diagrams to trace battery and PMIC output rails, follow charging, USB and SIM lines, and pinpoint parts responsible for display, audio, network or no-power faults, including shorts on supply lines. Any PDF reader opens it, and component designators can be searched directly. Compare the board marking printed on your handset's PCB with the document before relying on its values.
