Schematic for the Xiaomi Mi 5s in a zip archive of 876 KB. No board number or revision is mentioned in the name, so read the drawing title blocks for that detail. Schematics like this are used to trace power from the battery connector through the PMIC, follow the charging and USB circuitry, and locate parts on the display, camera and ultrasonic fingerprint sections. They also show which components share a rail when tracking a short. Make sure your board version matches before relying on values.
