What were the longest flight times you could get? In my case, the longest time is 24min 09 sec. in flight mode N. Mostly, however, I have about 20 min.

21 & 20 minutes at around 20% battery left (low battery alarm)

Hello there. Good day and thank you for the inquiry. I hope that our fellow DJI co pilots can share there longest flight time when flying there DJI Mini 2. Just a reminder that the DJI Mini 2 has a Maximum Flight Time of 31 mins. ( measured while flying at 4.7 m/s in windless conditions ). Thank you.

It always best for the battery to land with 20-25% battery left,  you batteries will last longer for it.

Longest flight time: 25 minutes with 6% battery, total of 5.8km flown,
Longest total distance flight: 7.8km in 18 minutes with 25% battery remaining at landing.

When I talk about total distance, it isn’t the distance from the home point to a BVLOS but it is the total distance flying in VLOS in a grid or circular pattern, depending on the photography mission. Max distance with VLOS is around 500m to 600m, depending on the weather and lighting conditions.

Sadly the weather has been rather poor of late, too wet and windy. Weather improves next week but will a wait and see how I am after surgery tomorrow.

I always try to land with a minimum of 20% battery remaining.  22 minutes is about average for me.

I believe the length of the time depends on speed: mode (Cine, Normal, Sport), temperature, wind, starting/stopping, gimbal position (straight down would be less aerodynamic)? Even full speed on Cine mode is about 8m/s and DJI Stephen says best is at 4.7m/s (no wind)

I tend never to look at my length of time flying until I review the flight statistics in Airdata. As soon as that little machine says low battery, I'm looking for the quickes and easiest way home. Airdata shows a couple of my flights at 24 mins duration with others between 19 and 23 mins.

24mins at 5 degrees. I think it will be much better at 15-25 degrees

I have calmed down a bit after what you write. I'm on average because I already thought my batteries were defective. The Airdata website shows large spans on the electric capacity scale from 1900 to 2100mAh.
