The wind, how fast you fly and other factors influence the total flight time. The advertised flight time is at the optimum. Hovering, no wind, no video camera recording. Be sure you don't try to push the envelop on the batteries until you get a few flights on them. I typically fly and record video for 12 minutes and that gives me time to land with 30% battery left. If I went 15 minutes, that would run the battery down to 10%, which is not a good practice-- that is pushing the envelop IMHO.
