The issue here is the Battery Percentage is based on a static voltage value.
The MilliAmps is where you get how full the battery really is......if you start a flight with a battery that was flown 5 days ago to say...80%......then it sat for 4 to 5 days....when you put that battery in the AC it might read a battery % of about 50-60%
HOWEVER, and feel free to test on your equipment.....put your AC in the air, stay low and close....then TAP the battery % to see the cell voltages.......if the cells are under 3.7 volts then at 60% you are already in trouble..... 3.7 volts / cell is similar to 25 to 30% battery......
As your flight continues and you get THAT battery down to 30%, check your cell voltages and see they are in the YELLOW and even RED below 3.6 volts per cell.
Please test and report your results based on this...... The P4Pro, and V2 as well as Inspire 1 and Mavic 2 Pro are all the same.......Put in a 50 to 60% battery and the voltages WILL NOT support a 15 to 20 min flight...might not even support a 5 minute flight.
There are so many posts in this DJI forum about "Why did I loose my aircraft?" and when the flight logs are reviewed, they started with a battery at 40-50-60% and lost the bird 5 to 10 minutes into flight.
Many don't understan why the AC "just landed"....it's because your 40% reading was incorrect and the bird landed because NotEnoughPower To Fly To HomePoint.
FYI my flight milage is over 4,300,000 ft ( not updated by DJI for some reason ) Over 1060 flights and 300+ hours of flight time.......I have not had a battery issue related to starting a flight with 100%.
