Full schematic set for the Apple iPhone X, delivered as a PDF inside a 10.7 MB ZIP archive. The name gives no logic board number, so confirm the 820-series code on the board you are working on matches the drawings. The larger file size suggests a complete set of pages covering power management, baseband, audio and display circuits. Technicians use it to trace rails, check expected voltages and find the cause of no-power or no-boot faults on the sandwiched logic board, ideally alongside a matching boardview.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @Schematics_Mobile. Enginerys does not host this file.
