: Pinpoint specific failure-prone ICs, such as the Power IC or Display IC.

These give you a higher-level, simplified view of how different subsystems (Audio, RF/Antenna, Cameras) connect to each other.

: Technical references for the power distribution network, which are critical for fixing "dead" phones or power-cycling issues. Hardware Solutions

Identify critical test points to measure with a multimeter, ensuring the battery (typical 3.7V to 4.2V) is delivering correct power.
