Sounds like good advice to me - just wish there was a way of turning off USB charging at will, seems like a flaw not a benefit. Maybe DJI will come up with an upgrade for the controller that will enable a charging disconnect

DJI already enable the no charge message to the mobile device; some android devices choose to ignore this. iOS devices also use to charge but listen to upgraded controller firmware message and doesn't charge anymore. In fact on initial connection an iOS device will initially indicate charging and then shuts off charging. Bottom line, you probably will not see an update from DJI because they already did; balls in googles court or your mobile device vendors court.
