I had a fully charged iPhone 6s plus, which after 3 flights died mid-flight. For one, that's terrible battery life, so I don't know if DJI GO is to blame or my iPhone has issues. I'll definitely put it on Battery Mode next time to avoid background apps. Do folks fly in Airplane mode to disable cellular data being pulled constantly by DJI GO (for map data)? I see the other upside to this being less interference with the controller signal.
After this happened, I was luckily in line of sight, so just flew manually with the controller to run down the battery. However, since I didn't have a screen I couldn't cancel the RTH. I was <10 ft from home, so according to the manual it should have not gone up to RTH altitude at that distance, but was trying to. I was 5 ft off the ground, so pushed down on the controller to land, and it refused. It just hovered. And every time I let go of the controller, it tried to take off. I ended up switching from sport mode to standard, which for some reason allowed me to land it, but WTF happened? In retrospect, I should have pushed the Flight Pause button, which my have stopped RTH, but why were manual controls not overriding RTH and why did it try to gain altitude when it was literally <10 feet from home? Cornfused.
