I have the phantom 3 Advanced, and I can't get through 1 flight without my iphone battery going down to 1% and subsequently dying. The phone isn't even a year old. I need options. I already have tried: *turning off wifi *using airplane mode *reducing video quality Nothing seems to make a difference. One time I lost 40% of my phone batter while the IMU was just warming up. Is there a way to both charge the phone and run the app? VERY ANNOYING I need options!
