Repair staff rely on such pages to identify which capacitor or coil sits on a shorted rail, to follow battery, charging and PMIC supply lines, and to check signal paths between the board stack and flex connectors. Open it in any PDF viewer and search component designators or net names. Verify the model code on the back label or in settings before trusting values, as other regional variants may differ.
