    I actually never flew a drone before and my first try was quite frightening. But it went well. I got the feel for it and flew around although not too far (about 500m away and 120m up in the air).

    1) I got the fly more pack and I must say, it's a must. But I want a 4th battery. The big charger supports 4 batteries. I however noticed that my controller had about 15% battery left when all my 3 Mavic batteries discharged (and I swapped them out at 25%). Is there a way to boost the battery on the controller? Without more battery on the controller, getting the 4th Mavic battery would be a waste. Is the controller maybe charging my phone while it's connected? Edit: it seems it does. How do I turn this off?

    2) Are there any bigger Mavic Pro bags? The one that comes with fly more pack is fantastic, but it can barely fit everything, and if I get the 4th battery I will not have a place for it. And I'd like something to fit my DJI Goggles as well.

    3) I'm unable to set head tracking. There is simply no option for head tracking in DJI Goggles (although it does have head tracking sensitivity option). I watched some YouTube videos but could not figure it out. I have the latest firmware on everything.

    4) Compass calibration, where is it? Mavic never asked me to calibrate the compass and I'm unable to find that option.

    This thing is a blast!

    Welcome and Congratulations! The Mavic is a lot of fun.
    For your questions:
    1) The fly more kit includes a Mavic battery to USB adapter. You can use that to plug a mostly used Mavic battery or a USB battery pack into the side port of the RC while you use the RC USB plug to connect to your phone. People have tried various hacks to cut off the phone charging with mixed results.
    2) There are many bags for the Mavic. Just do a search on this site and you will find many discussions complete with pictures.
    3) Can't help, I don't have the goggles.
    4) If Go 4 does not tell you calibration is needed then you can skip it. Compass calibration instructions start on pg 54 of the manual. There are also many videos on line that show this.

    Read the manual and have fun!

    Thanks for taking the time. I did some reading and since my phone is rooted, I will try one of those apps that stop USB charging. It seems to be the easiest solution.
    I will post the goggles question in the correct forum.

    I wish idiots would read manual before asking a bunch of questions.

    Oh look, it's me who made this thread! :rolleyes:

    Today I almost learned the hard way not to mess with low battery.

    I was about to land manually around 4 meter from RTH location (while in fact it it was about 16m, I think it miscalculated during RTH setup), but the Mavic suddenly initiated RTH and started ascending.

    There was a single power line straight above it and I can tell you I almost pissed my pants but managed to avoid it.
    Then it suddenly started flying past RTH location and away some 20 meters before I stopped it and flew it back manually.
    Update: this is because of me. I pushed forward instead of up because I am still not experienced with the controls.

    It was at about 18% battery. When I reviewed flight logs it initiated RTH because battery was only enough to get home. Which is weird as RTH spot was 16m from it.

    Is this a bug or a normal safety procedure? I almost crashed it because of RTH option. I know there isn't, but I wish there was a way to turn RTH off completely.
    I can imagine there are plenty of crashes because of it even though people just wanted to mess around with their drone in 5x5m radius.

    New MPP owner too, and while I'm still wet behind the ears, I was able to solve the controller battery burn pretty quickly. Firstly make sure whatever device you are using to run the DJI Go 4 app is fully charged. This is important as the controller will cannibalize itself to charge that device, so starting with a fully charged device will minimize the loss. Also, instead of using the adapter to waste one of the drone batteries, just get a cheap Anker battery bank. I already had a 20K model and I've found this is pretty handy to have out in the field. Good luck.

    Perhaps you did not notice but Go 4 gives a notice it is going to RTH with a 10 second count down. This notice has a cancel option in it. You can also cancel by pushing either the RTH or Pause button on the RC. I think switching in and out of Sport mode also cancels RTH.

    Thanks for the input but I don't have the same issue as you.

    I don't waste drone batteries to charge the controller. The controller is nearly drained after using 3 batteries because it's at the same time charging my phone.
    I need to stop it from charging my phone before I can get the 4th battery.

    Perhaps the volume was turned down and you did not notice the announcement or you do not have Smart RTH turned on.

    Never mind then. Seems odd that after 3 batteries I have well over 35% left in the controller, but it sounds like you have it all figured out. Good luck.

    BTW, as a follow up for the others. I did a little test today to confirm a hunch.

    I brought the controller battery down to 50%, and my tablet down to 90%, so I knew the controller would be cannibalizing itself. I connected the two via the center controller USB port. I then started the bird and let it hover.

    I then connected my Anker battery bank via the left controller port and stuck it in my pocket. I could easily see the controller battery was charging, and even under the load of itself and the tablet, quite rapidly. By the time I finished my first flight, the tablet was at 100% and the controller was at 60%. So there you go - Easy solution.

    I actually like the fact that the phone gets a charge from the RC. I also have the platinum fly more combo. Somtimes when im done with 3 batteries the RC is still at 50%. Sometimes down to 40%. And my average flight per battery is around 19min down to around 20-30%.

    Just try to start off with everything close to 100% charged.

    Yeah, I don't know what the root of the OP's problem is, but you can easily get through 3 fully batteries (1-1/2 hrs) of fly time with a fully charged controller, if the device is fully charged. As matter if fact, going through 4 or perhaps even 5 batteries should be within reach. If you use an decent size Power bank that you can run concurrently, the number of batteries you can use consecutively is pretty much unlimited.

    I have a Note 8 and set the brightness to highest because I can't have it lower while I'm out in the sunny day.
    Currently there's no way I can use 4th battery without finding a solution. Connecting a power bank is a possible solution but I would rather stop my phone from charging.

    I would hazard a guess that the note 8 is quite power hungry at full brightness! I also run full brightness. A power bank might then be your only solution.

    I run a full size Samsung Tab A 10.1" at full brightness and like I said, I am not encountering the drain anywhere near what you are reporting. You might want to look into what might be running behind the scenes on that phone, turn off Bluetooth, put it into Airplane mode, and make sure you don't have a bunch of widgets or apps running in the background. Check the battery icon to see what are the worse battery hogs and shut them down. Seems to me, if you are truly starting with a fully charged phone and controller, unless something really wacky is going on with it, the phone should not be that voracious. If you cannot sort out what's going on with the phone, then you really have two choices: A) be happy with running 3 batteries during your outings, or B) get a battery bank. Good luck.

    The FMC set comes with a Mavic battery to USB adapter. After using the battery for flying there is enough power left to run the RC.
