Schematic for the Apple iPhone XS, supplied as a single PDF of about 934 KB. The name gives only the model and no board number or revision, so check the logic board against the document. A phone schematic like this helps you trace the power rails from the PMIC, check the lines from the battery connector and charging circuit, and follow signals to the display, camera and baseband sections. The PDF can be searched by net name in any PDF reader, which speeds up locating a rail during a short-circuit diagnosis.
