Had my first 'pit of your stomach' moment the other day. Flew a 1000m across an abandoned gravel pit then straight out over open ocean. Took a picture of a tanker anchored, but kept my distance so I didn't get any interference. Checked my signal, which was great at 4000m out, but then noticed I had dropped from 17 to 13 minutes of flight time over 10 seconds.
Thought something had gone wrong with the battery, or RTH, so all I could do was head back and hope the Mavic didn't die over open water.
Of course, I never looked at the battery % in my light panic, and see now it was just extra draw against a stronger breeze. Made it back with 30%; helped that the wind was against me going out (had checked) so less power consumed coming back. Was a relief seeing the flight time stabilize and making it back over land!
