Xiaomi Mi Max 3 schematic, a compact 1.00 MB zip archive. No board number or hardware revision appears in the name, so verify the version on the schematic pages themselves. Such drawings are used to follow the battery and charging circuits, trace PMIC outputs and locate the parts feeding the large display, audio and camera sections. For a short-circuit diagnosis they show which capacitors and ICs sit on a given rail. Match the PCB markings to the document before replacing components based on it.
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 @esquematicosparatodos. Enginerys does not host this file.
