Service archive for the Honor Play smartphone from Huawei, packed as a 2.32 MB RAR. The name only identifies the device and says nothing about the document type, so open it to see whether it contains schematics, layout images or something else. Such data guides a technician through power management circuits, battery and USB connectors, and test points when diagnosing no-power, no-charge or short faults. Verify the board marking against the documentation before measuring or replacing parts.
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.
