Have my iPhone + Control (using RC). After not long time using, I noticed that the baterry gets drainned pretty quick on the iPhone. Anyone noticing this behavior?

Thanks!

Are they both fully charged when you started?

Kind off, iPhone dropped from 73% to almost 40% in 15 minutes. The iPhone baterry stats, shows that DJi GO is using around 91% of battery.

I'm sure many people have reported that the little short lead from iphone to transmitter uses it as a charger, hence draining the iphone. I'll have a look round the forum for examples.

I flew in very cold weather last weekend - my first two flights drained the battery on my iPhone 7+ from 100% to 60% then my 3rd flight drained it from 60% to 3%... freezing cold temperatures massively drains iPhone's. Flew today in warmer temperatures and it had 52% left after 3 back-to-back flights!

Thanks A CW, charging full now my RC and iPhone.

I always head out with everything 100% charged mate - especially if flying in cold temps. Keep the phone in an inside pocket when walking to your flight location to keep it warm. & I have my screen brightness level at around 90% rather than max - that helps too.

I have the same issue with my iphone 6 and Mavic pro, where the battery drains out very quickly. The max would be one battery (or less) with a fully charged phone. Possibly the RC is being charged by the iphone. I live in warm country in southeast asia and have never flown the mavic in a cold climate. I always use a USB (iphone complient) cable which is connected to the bottom of the RC. This is a serious problem. I wonder whether there is any way to overcome this issue?

Have glanced thro many posts in this regard but no solution seems to be available.

I hope the engineers at the DJI will address this if possible with a firmware update.

iPhones and all iOS devices are basically allergic to the cold.

Can turn that option off. Never noticed the battery on my iOS device run down down quickly. More specifically my iPhone battery seems to use surprisingly small amounts of power after drone use. What’s the health of your battery like?

Of course Always make sure all other apps are off and maybe consider flying in airplane mode .
Good luck and happy safe flying

My iphone battery health is 90%, which is OK. RC, MP and iphone 6 is fully charged. I fly on airplane mode and in a warm climate. I suspect that the Iphone charges the RC while flying ! Can this be turned off ?

Pretty certain this can be turned off. My iPhone has never charged from the remotes but after setting up a new Nav Pro 2 I'm sure I saw an option regarding charging external device. Too long ago for my Nav Pro and Air and as you can imagine I don't use them as much now as my Mav 2.
