Persian-language PDF explaining how signal and power line names are used in iPhone schematics, according to its title. It works as a reference for reading Apple net labels, such as the prefixes and suffixes that mark power rails, buses and control lines, rather than as a schematic for any one model. No specific iPhone generation is named. It is useful alongside a real schematic and boardview when tracing a fault, but naming conventions shift between generations, so confirm against the diagram for the exact phone.
