Drone lost after 2nd Battery Change - Did not return Home
I was flying today and on the second battery change on same mission the drone initiated the RTH at 20% Battery.
It then stated it lost RTH and started flying in the wrong direction. It would not allow me to control the steering controls and but allowed me to control the Camera.
I was able to see the drone land in woods but can't find it. Is there a way to pull up the last known coordinates?
Currently I have an Air2s missing in the woods and hope to find ASAP.
I have the Elite Membership if that helps.
Thanks in advance

A few ways but easiest would be if you use Airdata for your logs. You can also look at that flown mission in the Web app and see where the last recorded location was which will be the drone Icon. It will give you at least an idea of the area and which way it was heading. You can also access the logs on your device as explained I the help article I’m sending a link to. You can try find my drone but it will only give you the same last recorded location as the Web app does. In the future if this happens you can go to that approximate location where you saw it descend and wait for it to connect again and then use the find my drone. If it does connect then it will show where it is on map and you can trigger the lights and a beep sound. Also a link to how to take control of the drone a few ways. I have a feeling while returning in went into critical low battery and then at that point it will auto land. If it disconnected for whatever reason then you would have no control but to would still try returning until the critical low battery. Also if it did trigger RTH on the low battery then it would return to the recorded home-point so it would not go in another direction. If it did then there maybe somehow it got changed or possibly a drone issue. The DL app doesn’t control the RTH behavior as that is all controlled by the drones firmware same as when using the DJI Fly app. Let someone know if any other questions. If you want to share the plan maybe someone can find a possible reason why it reacted the way it did.

Thank you for the quick response. I was able to download the flight log but I can't seem to figure out how to view it.
Thanks again for help
I don't know off hand if this will work if the drone is no longer connected. I know if you were using the DJI app it will remember the last location.
If you're really lucky you still have a connection and this could save you.

I was able to recover the drone with no damage.
Downloaded Flight Data
Processed in AirData
Exported KML
Used Google Earth Pro on Computer for initial reference
and
Used Google Earth Mobile Edition on iphone to use my phone to locate myself in relation to drone.
5-10 min hike in the woods and it put me on the exact location where it went down.
It was .55 miles away from original location.
Drone is ok and I am very happy to have recovered it.
Thanks to all that posted, much appreciated.
Good to hear you recovered it ok, I know what a relief that is had a similar experience myself last year
Airdata - Notifications - HD Flight Player was very detailed but it just stated that it was Mode Changed to Go Home
Maybe I flew the mission to soon after battery change and closed the DJI fly before it got the proper RTH?
It marked this as B on the Map and B was home.
Without seeing the entire log there is no way to see exactly what happened. All the screen shot indicates is the initial status of Max altitude, RTH altitude and the take off. Would need to see what the battery percentage was, when RTH was triggered, how far away from the recorded home-point. Also it doesn’t matter if you closed the DJI app or DL app the RTH is controlled by the drones firmware. So if RTH is triggered by a low battery, triggered by the pilot, or a disconnect between the drone and controller it will RTH based on the drones firmware. Once a mission is completed DL has no control of the drone. If you want to find out exactly what happened you could save the flight log to something like Google drive and share it. Since you found it a half a mile away it sounds like it was farther a way then that at some point and while returning the battery hit the 10% critical low battery which then goes into auto land. In the future when flying any mission at a far distance you are better off triggering the RTH manually at maybe 30% so it has enough battery to return all the way back. You don’t need to wait for the low battery to auto trigger RTH. This way you won’t take the chance of coming up short. If you want further help just ask. Enjoy.
When i lost mine and looked at the Airdata log afterwords it showed a loss of power, and on another occasion when i clipped some branches on a tree the reported indicated the drone was at an acute angle before it miraculously recovered and carried on flying twice, so yeah give the Airdata report a good read especially the notification tab
