Why does my drone never hit its advertised flight time?
Short answer
Because the number is measured under conditions nobody flies in, and because several makers add two batteries together. Expect roughly 60 to 75 per cent of a headline figure in real use, land with a reserve, and read the conditions the maker quotes — they are printed beside every flight-time figure on this site.
Three different tests, one number
DJI quotes the Mini 3 at 38 minutes "hovering in a windless laboratory environment, in photo mode, from 100% battery level until 0%". It quotes the Air 3 at 46 minutes at a constant 28.8 kph with obstacle avoidance off, AirSense off and the camera set to 1080p/24. It quotes the Neo at 18 minutes flying forward at 2 metres per second, which is a brisk walk. These are three incomparable tests reported as one kind of number.
The addition trick
At the budget end the headline is often arithmetic rather than engineering. "62 minutes" on an Atom SE listing is two 31-minute batteries. "80 minutes" on a Holy Stone HS600D is two 40-minute claims. "64 minutes" on a Ruko F11GIM2 does not even match the maker's own 28-minute-per-pack figure. Nothing in any of those boxes will stay airborne for an hour.
What the gap actually measures
Where a third party has measured a drone, this catalog records it. Holy Stone's HS600D claims 40 minutes per battery and reviewers measured 20 to 25. Potensic advertises 32 minutes for the Atom 2, a reviewer could not exceed 20, and a Potensic spokesperson put typical real-world endurance at around 20. Those are the largest documented gaps here, and they are documented rather than estimated.
What costs you minutes
Wind is the biggest factor — a drone holding station against a breeze is working constantly. Then hovering, which costs more than cruising on most airframes. Then recording: higher resolutions and frame rates draw more, and the video transmitter draws more at range. Cold weather cuts lithium capacity sharply. And every sane pilot lands at 20 to 25 per cent rather than at zero, which removes a fifth of the quoted figure before anything else.
