Schematic documentation for the Xiaomi Redmi 10X smartphone, a 3.65 MB PDF. Smartphone schematics of this kind cover power management, battery and charging, display, camera, audio, SIM and memory card circuits, and the connections around the SoC. A technician uses them to find which rail a shorted capacitor belongs to, what voltage should appear at a test point, and how flex connectors are pinned out. Open the file in any PDF reader and check that the model and board version of the phone on the bench match.
