I routinely get 35-40 minutes, filming about half the time. That's using sport to and from where I'm filming. I return with between 20-10% battery left. That's with landing gear, a battery lock and a tracker as a payload. I don't fly when it's real windy but it's generally a mountainous region so we deal with the mountain draw, lee waves, and regular up & down valley type winds. So depending on the time of day I'm flying the wind effect is different. I use this to my advantage. This drone handles the wind like no other! It barely budges from the flight path. I plug the batteries in the night before or morning of flying. This system works fine for me. I'm still on my original batteries and they work as good as new so far. There has been times the wind picks up unexpectedly (my grandpa would call this the rotor) & I ended the mission & returned home with the battery depleted more than usual. The return flight is usually windward when I'm not filming, while going to the site is most often down. I save battery this way. Although it can be a risky approach. As coming home is when I see the battery depleted the most. I also use the terrain with something called the ridge effect to help mitigate the battery loss. But I know the area & its behavior well. I come from a family of small aircraft pilots, mainly dropping off skydivers, hang gliders and training pilots. I myself never had the stomach for airplanes though. Depending on the conditions my battery can be depleted more or less than normal but it's usually to be expected. I would actually expect better battery life in a less mountainous region.
