I ran a test to see how long my battery would last if I powered on the controller and the Phantom 3 pro and let both devices sit with no activity. The battery drained linearly from 98% to 60% at 1% every 3 minutes. I have a plot but I cannot get the excel chart to paste in this thread. I think I could have saved a little more of the battery if I turned off the red LEDs by de-selecting "Arms LED light". I logged the remaining battery percentage from my tablet every 3 minutes while I was in P-mode. The temperature outside was about 65 degF. It took me over two hours to compete the test. After the test, I activated the props and started flying. I had about 12 GPS satellites during the entire test.
