If the device shows 0.00A or fluctuating low current on a USB boot meter, the primary power rail is likely compromised.
: Often based on the MediaTek Helio P35 (MT6765) architecture, detailing internal connectivity between the AP, memory, and sensors. Power Management (PMIC)
Indicates a short circuit to ground.
Integrated overvoltage protection (OVP) and switching charger circuit.
No. Do not confuse them. The A15s uses a different PMIC. Using an A15 schematic on an A15s will destroy the motherboard. The fixed PDF clearly states CPH2185 only . oppo a15 schematic diagram pdf fixed
Trace the VBUS_5V line coming from the sub-board via the main FPC flex ribbon cable. Ensure 5V arrives at the test point near the mainboard interface.
