Schematic for the iPhone X, 2.48 MB PDF, with a contributor handle and a misspelled word in the name. Apple schematics map the PMU outputs, charging circuitry, audio, baseband and display or Face ID connector signals across the board. They are useful for measuring expected voltages and tracing a short to a specific component. Open the file in a PDF viewer with search to find nets by name. Pair it with a boardview file for the same logic board to locate parts physically.
