Apple iPhone 5S schematic for logic board 820-3292, revision A, a large 72.5 MB PDF. The 820- prefix is Apple's standard numbering for main logic boards, and the letter suffix marks the revision. Technicians use these pages to trace power rails from the PMU, follow signals between the SoC, baseband and peripherals, and find components on a shorted line. Open in any PDF reader and search net names. Check that the number and revision printed on your board match before relying on the values.
