Schematics for the Apple iPhone 8 Plus, compressed into a 2.54 MB RAR archive. No board revision or modem variant is noted. These pages are used to follow the PMU power tree, inspect charging and USB circuitry, trace audio and display signals, and find which part pulls a rail to ground on the logic board. Extract with WinRAR or 7-Zip and read the PDF in a standard viewer. The 8 and 8 Plus boards are different, so confirm the model before matching component designators.
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 @Schematic_ir20. Enginerys does not host this file.
