The S9 is several years old now, and battery failures and charging port issues are common. Without a schematic, diagnosing a dead board is guesswork. With it, you can trace the BOOT_ON line from the PMIC or check the VBUS signal from the USB-C controller. For example, the S9 schematic shows that the main power rails (VDD_1.1V, VDD_2.0V, VDD_3.3V) must appear in a specific sequence. A missing sequence tells you exactly which IC has failed.
Liquid corrosion destroys tiny capacitors and breaks traces. Using the schematic, a technician can identify that a corroded component near the SIM slot is actually a line filter for the antenna. By checking the schematic, you find the "test points" to verify continuity, saving a board that would otherwise be declared dead.
