Hey gang, Ok Phantom 4.. Standard I guess. I charged my battery last Sunday. Before I went out to fly today I put my battery on the charger to see if it would charge any, like I said it has been a week. I plugged it in and the lights didn't start scrolling so I figured it was still fully charged. So I went out to fly. I flew for a while and landed when it got down to like 15%. So I figured I would just let it sit and idle with the props on and drain it down to 8% but when it hit 9% it shut down on its own. Just sitting, not flying. Now, my question is did this happen due to the battery sitting for a week and then when I flew maybe the calibration of the battery was off? I have the auto discharge set at ten days. Thanks for the help
