I bought a DJI Mic last month and have used it a few times. To my surprise, every time I open the case, the receiver battery is dead, even if the case itself has plenty of battery (i.e. 4 solid LEDs on the case).

The act of opening the case triggers the receiver to re-charge (which of course takes quite awhile). But if I leave the receiver in the case (closed) for about 24 hours, next time I open the case, the receiver is dead again.

Thankfully the transmitters record locally so I was still able to get the audio I needed, but in a much less efficient way.

Is anyone else seeing this problem?

Oh, and receiver and transmitters both were immediately upgraded to the latest firmware, and the menu confirms that the latest FW is what is running.

Yes and how do we avoid having a dead receiver when we want to use it.
