It was 7 the last time I noted. Was a little busy flying. 
I had just done an auto take off so altitude was ~10 ft. Was in "Fly" mode. It came to a hover and began small movements on x and y with the controller when it stopped responding and started to slowly drift and lose altitude until it hit the ground. Motors didn't stop so had to carefully release the battery without slicing my wrist.
