Yes, the issue is that Androids do not provide a means for apps to disable charging, and USB standards state that a USB host, RC in this case, needs to provide at least 500mA to a target device, the phone/tablet in this case. So, the Android goes into slow charge when connected to the RC, drawing up to 500mA from the RC.
In other Mavic models, you could connect the phone/tablet to a USB A port on the bottom, and a power bank on the side port in the same way you'd be charging the RC.
For the MIni though, there's only one USB port, the one on the side. It can only be in one of two modes:
A/OTG mode: acts as if it is a PC from the phone's perspective, providing power to the connected device.
B mode: Accepts power for charging, also accepts connection as a device, usually with a PC for transferring files from the SD card, and communication with Assistant for firmware updates.
So how about opening the controller, and placing a jack in parallel with its battery? Then "plug in" an external battery / power pack?
