Controller battery life is limiting factor.

    I have a Mavic Pro Platinum

    From the few flight sessions I've had so far it appears to me that the battery life of the remote control is the limiting factor for a day out.

    I have 3 batteries so that's around 1 1/2 hours of flight time. The ipad I have connected to run the DJI Go 4 app, has a battery life of pretty much all day.

    Flying recently, by the time my 2nd battery was used (so an hors flying time give or take) the remote control was indicating low battery. It had been fully charged when I started.

    With it's integral battery (not swappable etc) this seems to be a major problem !

    1. Is this typical of remote control battery life? Should it be longer?
    2. What solutions do people use when going for a day out?

    Shouldn't be doing this, are you using an OTG cable between your controller and ipad? If settings are not correct, the controller will be charging the ipad and cause the controller to drain much quicker

    OTG cable? I googled and it says OTG = 'on the go" but that doesn't make clear what one actually is?

    I am using the charger cable which came with the ipad.
    Connecting it to the bottom full size USB port on the controller.

    Is there some special USB cable I should be buying (keeping in mind its a new iPad)

    OK I think this is what I needed to know ?!

    So now I just need to find an OTG cable with right angle lighting connector at one end (for ipad) and standard usb size plug for controller end - and which I can get promptly here in Australia.

    That has a USB female though, surely a male is needed?

    What about this on my ebay?

    That wouldn't work as that is just a data transfer cable. Sorry I wasn't explicit enough in my explanation, you need 2 cables. The OTG cable I linked plugs into your controller. Then you have a short cable with a male end that plugs into your phone like below. Male end of this goes into the female end of the OTG cable. Now you have a physical one-way connection between your ipad and controller

    Cheers but both have lightning? Surely that's only for the ipad end?

    Yes, controller and ipad both have lightening connectors so you'd think that you could just connect them with a cable. But no, the OTG cable has a "dongle" that converts the sent signal. So you have an OTG cable connected to your controller, and a USB cable connecting the OTG to your ipad

    Which essentially just makes a longer OTG cable. yes.?

    I thought the connector on the controller is micro-usb.... ?

    Anyway if your way definitely works and doesn't drain charge from the controller, then that's what I'll do :)

    A picture is worth a thousand words, here's how it's connected. OTG cable plugs in to controller, then cable goes from OTG to tablet
