Same issue for us in the Lite Plus forum. Autel has not updated the Apple Store with v1.7.25 so we can’t get the latest firmware either. Autel support notified me they don’t have a schedule yet for when it will be released.
Are you REC. the whole flight ?On purchase, I upgraded mine to 1.98 and only every used it on that firmware.
Does anyone notice poor battery life on the latter firmware? I have no comparison. All 3 brand new batteries have horrible endurance.
I get horrible endurance (battery life / flight times) on all three brand new supplied batteries (Nano+ package with the 3 batteries etc.)
Typical flight endurance is maximum 17 minutes, despite "specs" stating around 28 minutes and anecdotal reports of around 24minutes.
All batteries have now cycled about 6 times and all batteries show no improvement for flight endurance.
The LONGEST flight I achieved was 17 minutes and that was hobbling home with barely a few percent in the tank. ie. Endurance is around 15 minutes safely.
STATIC TEST
I've also completed hovering test (garage...no wind) and still only achieve 15 minutes (landed at 9%).
CONCLUSION
Battery life is terrible, well below manufacturer claims and allowance for real world conditions, regardless of conservative flight modes.
Turn off OA, for the test.
