DJI Mavic Pro test 6500m Europe long range flight with 12% battery left

This is a EU version of the drone, with no modifications on the battery.
DJI claims the range is 4km, as you can see in perfect conditions you can reach much further.
No Sport mode used (consumes much more battery).
Returning was in Auto RTH Mode.
At the end of the video I tried to suck out all the battery to see how much longer can it go.
