ZIP archive of 10.8 MB for the Samsung Galaxy A6 with model code A600FN. The name does not describe the contents, so open it to see whether it contains schematics, a service manual or board layouts. Such documentation is used to follow battery and charging paths, identify PMIC outputs and find the component responsible for a short or missing voltage. Verify the model code on the phone label first, since related A6 variants can use different boards.
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.
