I received a Phantom 3 standard for Christmas and today was her maiden flight. We had it in the air for about 10 minutes, it was amazing, very stable, easy to maneuver, fun. Until I looked down and my iphone had shut off. I landed the drone and tried to get my phone back on with no success, it wouldn't tun back on until i plugged it in, here's the weird part, I assumed the battery had been drained, but when i plugged it in, it was still at 85%. What could cause this and how do I keep it from recurring?
