Statement:
'The theoretical max flight time 16 minutes (no wind at a consistent 12.4 mph (20 kph)), and the max hover time is 15 minutes (no wind), power consumption will speed up due to the different flight environment and usage of sticks.'

You can hardly reach these numbers, but what's your Spark's max flight time?

Open your GO 4 app, and via menu you can open the Flight Record section.
You should be able to sort your records by tapping Time.

Do not post screenshots, you are a pilot..we trust you!
But we love stories. Please share :-)

DISCLAIMER:

• Do not try to push your limits to improve your maximum flight times, we do not want to hear about lost Sparks.
• The only situation where forced RTH will happen, is when connection is lost between remote and aircraft.
• If you cancel any onscreen low battery warning about RTH, there will be no automatic RTH.
• At 10% battery, your Spark will start forced landing! Will be initiated earlier if your Spark needs more battery to land safely.
• You will be able to have some control, most important is to push stick to gain height.
• If you are concerned about battery health, do not drain your battery below 10-15%.
  

My own record is 13m 49sec...hence voted 13+.
Landed with 6% remaining battery.

To your one disclaimer-point,
"At 10% battery, your Spark will start forced landing!"
I can add something:
That is, when it will always critical battery land.

But the critical battery landing batt-value is calculated by the height over HP
That can start at 15%, 19%, ...., all a question of your actual flight height.

I have a couple of 14:xx min flights

Good point, it will not drop like a rock!
Thanks... updated poll.

Did hit 15:32 once with my spark in near windless conditions

Hello and good day Haggi. Thank you for reaching out and for this inquiry. I hope that you will get the best information from our valued DJI co pilots on what's there DJI Spark's maximum flight time? Thank you for your support.

14 and a bit minutes for me but still had a good percentage of battery left that could of squeezed out some more time.

If I go past 13, it wants to return home before I can land it in my hand.

Hit just over 15 min once. Generally I hit 14 min.

13 min 18 sec is my max. Landed with 6% battery.

13+ for me. Could probably go slightly longer, but I like to keep it safe and have enough juice in the batteries when I bring the Spark back.

My longest is 12 mins, but i'm still set to the default RTH settings (20% I believe)

I scored a 14:06 in my longest Spark fight, which according to the DJI Go 4 Application equates to 15 minutes of flight time....

Usually its 10 mins until battery goes down to 30%. I managed to do 15mins couple of times but that was silly, basically drained battery to 1%.

mine launched like 15:40 0r 50 ish

You can get a long flight time at the expense of battery life.
