Hi.

I just get my Mavic and have some problem.
After connecting phone to controller anr turnig it on, controller is charging my phone :-(.
I tried changing settings in phone (connection type: phones or files), disable/enalbe USB debugging.
I searched DJI go app and tried find some settings - no success.
My phone is android, all firmware, dji go updated yestarday.
I connected phone using left small port and tried using bottom large usb port

Can somebody help me?

Anybody have same problem?

I think that's just how they work, just have your phone charged before connecting and you won't have to worry about it draining the rc's battery.

It apparently will give a very slow charge nothing to worry about...

Just as hallmark007 mentioned,  you don't need to worry about it.

My concern is the other way around. My device is draining the controller!!
Unlike the P3/P4 GLXXX controllers, the mavic's rc controller battery is tiny.

Before the flight, please double check all devices and make sure all are fully-charged, including battery, remote and mobile device.

If your phone is charged before flight, like the controller and flight battery, then there will be little drain. It will just assist the phone. The additional drain on the controller should be minimal. If not, then your phone's battery is probably bad. Or, your phone is a Samsung (yuck) which are prone to charging controller problems inside the phone.

If your Android phone is rooted try : "Disable ADB USB Charging ROOT"

It will make no difference with a fully charged phone. The screen on the phone will chew up phones battery and the controller will start charging the phone instantly. This will drain the controller. Only way around is to use the Mavic Battery bank adaptor and charge the controller when you are no where a power source.

Rather than repost - can I give a link to my findings here so the DJI admins wont miss them...

But summary: I can see the I'm getting Half the life when using Android over IOS - I measured time to discharge and the actual electrical current draw on the wire from the remote for IOS and Android phones.

Id prefer to use Android but the battery wastes so fast - Thanks for any help!

Has anyone else tried this suggestion?

It is very bothersome to have the phone chewing on the RC battery and no way of turning that .45A drain off.
Thanks for your research Ozmo, hope there might be a work around as im not sure DJI will/can address this via FW

If it's an 27th just disable fast charge to avoid further battery drainage on the controller. Nothing to worry about.

That doesn't work. I tried it and my S7 would still drain the RC very quickly. "Fast Charging" is a very specific and different type of charging. It will only Fast Charge when connected to a suitable PSU. The kind of charging speed my S7 gets from my RC is not Fast Charge speed, but it does seem to be equivalent to normal charging from a wall charger.

The only fix for me was to connect my S7 to the bottom port instead of the side port. It now draws far less current.

Have you tried using the bottom port instead of the side port? This works for me. Although I notice that Ozmo's tests showed large current draw even from the bottom port. That is strange and I don't seem to get that from my setup (Galaxy S7).

Funny thing is that while Samsung users complain on the phone being charged while connected, iPhone users complain on the opposite

it's now March 2018

Was this issue ever resolved, I also have Samsung s7 edge and disabling debugging is not stopping the RC from charging phone, killing the RC battery life.
