The Redmi 13C (codenamed "gale") is built on a cost-efficient yet robust architecture centered around the chipset. Understanding its schematic layout requires focusing on three primary subsystems: Power Management (PMIC), Baseband/AP, and Peripheral Interfacing. 1. Core Logic & Processing Unit The heart of the schematic is the MT6769V/CZ AP/Modem SoC.
Verify if V_SYS is active (around 3.7V–4.2V) near the main PMIC.
