Yesterday I was browsing thru my 80+ flights and was astonished that I had No 20 min. flight (longest was 18-19 min.)So today I was cruising around and achieved 22 min. with 36-41 km/h and landed on 12% mark, so my question has anybody had 27 min as in specs?  

I got 21:45 with 21% remaining.

This guy was testing carbon fiber to OEM Props, interesting flight times under ideal conditions.

From the Mavic specs:
"Max Flight Time: 27 minutes (no wind at a consistent 15.5 mph (25 km/h))"

Hi Alex, the max flight spec of 27 min means flight must happen in most ideal circumstances which includes no wind, no extreme temps (esp cold) and also at most optimum speed for best battery efficiency which is 5m/s and which will not include hovering as this consumes more energy than slow forward flight.
Also it is apparently not good to delete your mavic battery to zero and i always like to be landed with some battery life to spare.
So for me i will probably never get 27min :-(

I don't believe the specs, there's no way the mavic fly's for 27 minutes going 15 mph. Under normal conditions i get around 18 minutes.

I regularly get 25+ minutes per battery.

Batteries are relatively fresh - all have no more than 10 charge cycles each.

I have my critical low battery at 10% and low battery warning at 20% - I often land with 12-15% battery life remaining and flight time of 24/25 mins

Do you understand the specs given by DJI?
What are "normal conditions"?

I get between 20 to 25 minutes from one Mavic battery flying a mix of P and Sport Mode with a wind blowing at around 2 to 3 Beaufort.
And with at least 10% battery capacity remaining.

Today I have tried with 25 km/h (roughly ;) ) and achieved 25.08 min ;) - it's very difficult to maintain this strange speed - I have tried tap to fly set to 25 km/h but sun as usual mad sensors stop the drone avoiding imaginary obstacles so in this direction I have to switch off VAS and tap to fly was not available for a while ;)Landed on 8% battery fighting urge of my Mavic to land immediately ;)

Exactly, no one gets 27 minutes, so in disagreement you confirmed what i said.....

From 27 flight so far, my longest lasted 22:03, with me landing at 18% battery. Half of the flight had two tours out with maximum distance of 500m and the second half of the flight was spent trying out various intelligent modes near me - a lot of hovering. Total flight distance 2458,8m.

I think if I were simply cruising and went down at about 12%, I could have stretched it to 24 minutes in the air.

Not true!
If you fly your Mavic as specified in the specs by DJI, i.e. no wind and a constant 25 km/h, 27 minutes flight time ought to be possible.
What other values should DJI mention in their specs?

BTW, I did a test this afternoon: Wind speed around 8 km/h and I flew the Mavic in square circles in P- and in S-mode.
I ended the flight time at 23 minutes and 48 seconds with only 5% battery capacity remaining.
That's not too far off of the DJI specs.

... if DJI had put max. 20 minutes in their specs everybody now was happy and not complaining they never reach max. fly time

You should be flying now...

It's a consumer grade UAV that comes packaged with marketing speak. There are UAV's with longer flight times. I bought my Mavic for portability and convenience. 20 minute flight time with acceptable video quality seems just fine. I'm not certain why this is being seen as an issue. We shouldn't be pushing the quad to the dregs of its battery in the first place.

I agree 100% with you,i never fly longer than 15 minutes minutes, the point im trying to make is that under any condition the mavic will not fly 27 minutes as it is advertised....

Absolutely.

As an aside, you seem to own a ton of DJI products. You probably understand the marketing speak better than most!

R&L Aerial  Posted at 2017-8-6 11:42

If you create the same conditions as the specs: Yes.
What other specs would your prefer? Your specs?

You are not making a point, because I'll bet you haven't tried.
I have come very close to those 27 minutes specified by DJI when flying my Mavic in P-mode only and with little wind at +/- 10 km/h.
Don't even expect to get 20 minutes flight time with a force 4 Beaufort wind.

" very close" let me tell you something, being close only counts when your throwing hand grenades or playing horse shoes. I have tried, no wind, 70 degree Fahrenheit, buzzing around at 15 mph and guess what? I got 22 minutes till auto land because of low voltage...not 27 minutes............

I get 23-24 mins regularly with it so 27 in ideal conditions is fairly plausible.  Seems an accurate figure to me.

Then again i fly it to take photos and seldom video so distances are never far, it spends a lot of time hovering and sport mode is used very very rarely.  I also havent butchered my craft with things such as skins, long legs, floats or anything to create more drag and weight.

I have a 25:15 flight and I was not trying to maximise  flight time. Just stooging around up to 500' and total distance was only 2 miles flown. Took off at 98% and landed at 10%.

I read a report of someone getting close ~ 28 min on a single battery, using fixed wing mode, which seems plausible. Fixed wing is much like a cruise control, so would do and excellent job of maintaining a constant power setting.

How many different batteries did you try?

Your screen shot shows that you rose up 3 meters and you flew out 3 meters then hovered. The specs show 27 minutes @ 15 mph, nice try though......

No, his record shows over 10 km of flight. 3m is the reference to the last point of flight as he landed.

...and he had 8% battery left.  Extrapolating to 0% battery, it takes the time  just over 27 minutes.

The mavic auto lands at 8%, so nice try skeeter.... What i want to see is a video of someone flying around at 15 mph for 27 minutes before auto land kicks in and until i do the mavic will not fly for 27 minutes as advertised.......

Then send it back.....

Flycaster Posted at 2017-8-8 11:43

You talkin to me????? You talkin to ME???????

Have a few flights of 25 min, otherwise they are usually between 20 and 24 minutes. It's not that bad for this bird.

You can override the autoland by simply holding the altitude stick up.  So as he said, 27 mins.

A completely plausible figure in ideal conditions.  Nothing i've seen elsewhere suggests that figure is inaccurate.

We've proven that the battery capacity is what DJI says it is.  I don't understand why you're still arguing the point.  It like saying that Ford lied about the capacity of my gas tank because even though they *say* it's 16 gallons, I can't realistically use all 16 gallons because then I'll be stranded.

When someone shows me a video of a mavic flying at 15 mph for 27 minutes, i will believe the specs. Until then....... As cuba gooding jr.once said " show me the money!!"

Approx. 21 minuttes "random" flight. Not trying to be energy effective, and recording video while flying.
Takeoff at 98%, landing at 22%:

Theoretically that would get me very close to 27min if I took off at 100% and landed at 0%, though that would probably be a very bad idea to try.

I'm very happy with the battery performance.

You simple bring a 1 gallon gas can with you,the same as bringing another battery." show me the money!!"

You mean like these from airdata which is what it could have done if i hadn't landed it early.  Still had 16% remaining so would easily have done 27 mins.  That was in a 18kt wind, high altitude and lots of hovering for photos so hardly the most efficient a flight could be.

i have a lot of 22-24 minute flights, but i usually don't go to the limit. as you can see, 23:49 with 19% battery left.
