I am the DJI Mavic 2 Pro user. It's been 10 days since I started using the drone. Yesterday night, while the drone was operating on distance from me around 900ft and the height around 129ft it suddenly lost all its connection and fell on the street.
The battery was 96% charged, I couldn't find out the possible reasons for brand new drone suddenly dropping itself on the ground and neither could use the shot footage as well.
It hasn't hit anything or had not any obstacles or obstructions nearby,  it wasn't even windy outside.
The drone was simply in the air and all of a sudden fell on the street. There must be some internal error in the drone itself, otherwise I don't see any other reasons.


I've included the screenshots of locations where the drone was operating (if that's any helpful at all).


What could be the possible reason of such incident and who do I get in touch with to fix it now?
Our project was interrupted in the midst of the work and the deadline is very soon, so there's a big time shortage at the moment as I'm running out of days to complete it.
I am located in Ashgabat city, Turkmenistan.
What would be the best option and urgent possible solution?
I would appreciate if you could guide me to next steps please.
Looking forward to hear from you.
Thanks very much,

The main cause of such unfortunate incidents are usually 1/ a bird strike 2/ one or more of the battery cells experienced a voltage drop - this is generally caused by the battery being fully charged then left for a long period of several days without being used then after take off the cells deviate as the charge is not strong enough to sustain the inputs - you should always take off within 24 hours of the batteries being charged 3/ a critical error occurring in the drone such as the ESC failing and causing the motors to stop 4/ the pilot accidentally performing a CSC mid flight

If you have recovered the drone then arrange for it to be shipped back to DJI Support in your region. They will carry out a full diagnostic evaluation to establish the root cause and if a manufacturer defect this will be replaced under warranty given that you activated the drone within the past 12 months.

Others can look at your flight log on here to help see the details of your flight and provide further explanations but none of us will be able to replace or repair your drone so given your tight time scales I would simply get the drone back to DJI asap. It can take weeks to replace though. Good luck.

Looking at the log - the batteries seem fine and there are no reported errors that I can see - which is odd given the sudden drop. So from what I'm looking at it's a case that a possible CSC was performed accidentally by yourself and I can also see you flew in a very built up area near main roads but as you said it didn't hit any obstacles. If there were internal errors leading to the crash this would normally show up in the log. It's a strange one.

The flight logs don't show any problems, no warnings and no sign of a user initiated shutdown based on the sticks. A deeper analysis may show different, but unless you ran into a power line or something it looks like it could be another case of a M2P dropping out of the sky. Only option now is to ship what's left off to DJI for a replacement.

E-mail them - it tends to be the quickest way to make contact. Once you have a case reference number an official DJI moderator on here may be able to speed up the process for you.

There is no power lines or anything. its just drop out of sky.

My sincere apologies for all the trouble it caused. I would recommend you contact our support team to start up a ticket: https://www.dji.com/support?site=brandsite&from=nav We have the professional team who would do their best to find out the crash reason and then the corresponding resolution would be provided. Please note that DJI will not perform data analysis for cases occurring after the expiry of the warranty period; hence, valid charges will apply. Thank for your support.

i don’t think this is true, nor i think it is written in the manual. it is a smart battery, or so it says. you say that if i not fly for two or more days my m2pro may fall off from the skies? the batteries do everything by them self, on you is just to pop them in the drone and fly. thats why you payed 1500eu and 120eu per battery, to fly and not to baby seat batteries.

What could possibly happen?

Well it’s not explained in the log from your device, this shows a perfect flight up to the end, no problems with anything including yourself.
I suspect the log from your craft may show what happened, so it will be up to dji to decide, I can tell you that having seen some similar cases that it usual that warranty will be awarded.

I wish you luck, I realize time is against you getting your drone for when you need it .
