Schematic diagram and service manual for the Redmi Note 4, a Xiaomi phone, provided as a 13.7 MB ZIP archive. The name does not say which chipset version is covered, and the Note 4 shipped in more than one hardware variant, so compare the board against the drawings first. Although catalogued as firmware, the contents are repair references, used for tracing rails, diagnosing charging or power faults and locating components. Unzip and open the documents with a PDF viewer.
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 @SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
