Schematic package for the Xiaomi Redmi 5A, filed as firmware although the name marks it as circuit diagrams. The 2.8 MB ZIP likely contains PDF pages that open in any reader. Technicians use such drawings to trace power rails, find which component sits on a shorted line and check signal paths for charging, display, camera and SIM circuits. No board revision is given, so compare part designators and layout with your own board before relying on specific values or connections.
