Pilots,
I'm going to revisit my suggestion about turning off sensors etcetera.
The response I got was that the motors are the primary energy hog, and everything else is insignificant in comparison.
I'm going to challenge that argument. While doing something as simple as a firmware update, my Mavic Air gets quite warm, even hot, and consumes a rather significant amount of battery. The motors never start (beyond a little twitching, as they do), let alone fly.
That heat generation is a clear indication of substantial power consumption. The LED lights may be insignificant, but the sensors, especially the downward sensors which are, I believe, radiating a signal, plus the electronic load in doing all the crunching to figure out if something is too close...
I'm not saying he's going to double his range, but the gains aren't nothing either.
