My drone was on a mission and I received a message that the drone needs to return home due to the remaining battery level.  I accepted the message and the drone started to fly home.  Half way through the flight, I noticed the drone reversed path and started to go in the opposite direction of the home point.  (It should be noted that the RTH homeport was properly updated prior to take off).  In any event, the drone flew a few meters opposite of the home point, maybe less than 10 or 20 in the opposite direction and then it landed.  Fortunately, I was able to recover the drone using the find my drone feature in the DJI App.  There was no connection to the drone (battery had died by the time I got to it - about 1 mile away from home), however, the remote controller showed the last location where a signal was registered.  Since I record all my flights, I was able to view the footage of what took place when it tried to land itself (halfway on the RTH trip).  
Essentially, the drone hovered in place for several minutes over the landing area, as if it was waiting on a command from the controller, and then it landed in a slightly wooded area.  Fortunately, I did not see any noticeable damage to the drone.  My question, however, is why did the drone not finish the RTH fight?  According to the flight records, there was about 20% battery life when it decided to land (about 1 mile away from the home point).  Where can I attach the flight record to for your analysis?

I think the auto land feature activates at 20% but can be canceled if still connected to the remote, I may be wrong about that though....Without seeing any flight logs it sounds like you had a head wind on the way back that the drone does not factor in when the low battery RTH ativates. When planning long distance flights you need to take consideration of the wind whch direction it is and how strong it is.

As usual, the answer will be in the flight data.

The out of the box auto-land preset is 10% and the out of the box low battery warning is preset at 30%

got that, those are all good possibilities....i was flying back at 120 meters....there was a fair amount of wind....when I eventually found the drone and reviewed the video, i noticed that it hovered for over 3 minutes in someone's back yard then it eventually landed, probably due to the battery running out...when i noticed it was about to land, I tried to cancel that but it immediately said the RC was disconnected from the drone...

Can you put up flight log as Labroids asked?

Sounds like you might have unknowingly canceled RTH.  

Please see Post 3 and Post 6.

Ahhh yes you are correct, at 20% it will pop up with the low battery RTH  message again, which you can still cancel out at that time.

Your Phantom will land when  the battery level is at a low. Does to matter what the commends are. Low battery, down she goes.

Hi there, it's lucky that the drone does not suffer too much damage. Is there any error message in APP and how about the performance? If yes, please kindly offer your DJI Account and sync the flight records, we'd like to look into.

yes, they were already synched....thx
