Apple iPhone 4S schematic in PDF form, about 650 KB. A circuit diagram like this helps trace power rails, check connections between the processor, PMIC, charging circuitry and connectors, and identify component values when diagnosing shorts or no-power faults. Any PDF reader opens it, and text search for net names is useful if the file is not a scanned image. Because smartphone logic boards have several revisions, compare labels and part numbers on the actual board with the drawing before relying on specific values.
