So I did a hover test today with 2 Zippy 1300mah batteries. I started with 96% on the mavic battery and and I hovered for 24:31 as you can see in the screenshot. When I uploaded the flight log to "Airdata UAV" it shows a much different story (see bottom pic) where it states that the flight was only 10:31 and that I landed with 62% battery left when I really landed with 13% battery and the flight time was 24:31.
Was the flight log just incomplete or is something else going on? Again this was only a hover test. I only took it up to around 3 feet.

The logs for battery life I think are mostly based off of the protocol communication from the mavic battery. So it Depends on how you have the mod wired. If your soldered to the main board the power may be bypassing the mavic battery board completely so it doesn't get logged.
Other mods that went to the pins may have had the energy charging the mavic battery, and then going back out to the mavic so the whole discharging time and data was logged and reported.
It's hard to say, especially when mixing different battery types together and how the mavic battery board handles the power, if it charges with it, passes it through and stilll logs it, ignore it beucase the of some built in safety shutting off a path?
Or the battery just is not logging for some other reason, bad contact on the data pins from the mod to the pins being to thick?
It's also hard to say for sure without knowing how the data logs are gathered and mixed to create these reports. I'm sure if they are looking at battery data for the flight time then it might be wrong. They should look at another log for flight time, maybe compass, GPS, motor RPMs or something else to figure out total flight time.
Could also be a simple error on the log application from some update.
