I’m used to the battery behaviour on the Mavic and this is the first time I’ve experienced a reporting problem in 12 months / 160 flights ownership. The error occurred within the aircraft as both Litchi which I was using as the flight software and Airdata which shows the data uploaded from the aircraft gave a landing battery of 80%. Airdata showed that the 80% level had been reached a 03:27 and was reported as 80% for the rest of the ten-minute flight.
I haven’t had a chance to fly again, a combination of windy conditions and my time being taken up with the forthcoming Reason to Fly photo competition I will take the props off and run it indoors to see what’s reported by the battery. Signal downlink was patchy as there were distances and trees involved but the data shows a downlink at varying strengths all the time.
So it’s bench testing and keep an eye on flight times when I get it back in the air.
