DJI MIC 2 (DMR02) Not Charging In Case

DJI Mic 2 Charging Case

The charging case contains the spring-loaded pogo pin assembly which is the most frequent point of mechanical failure. If the internal springs lose tension or the pins become stuck due to debris ingress, they cannot maintain the necessary normal force against the receiver's contact pads to complete the circuit. Additionally, the case's internal PMIC may fail to detect the receiver's presence, preventing it from switching the 5V rail to the charging pins.

DJI Mic 2 Receiver

The receiver's external contact pads are susceptible to skin oil contamination and galvanic corrosion, which increase electrical resistance beyond the threshold required for the charging case to initiate a charge. If the receiver charges via its direct USB-C port but not through the pads, it indicates a failure in the internal trace or the secondary charging protection circuit specifically linked to the docking interface.

Internal Li-ion Battery (RX)

If the 360 mAh Li-ion battery has reached its end-of-life or entered a deep-discharge state with high internal resistance, the charging case's safety firmware may reject the battery to prevent a thermal event. While the USB-C port might provide enough current to bypass certain logic gates, the case-docking logic is often more restrictive regarding battery health signatures.
