Updated the firmware to .0800 and also updated the battery firmware. Did all the calibrations then performed test flight.
Summary:
DJI Go 4.1.0
iPhone 6s Plus iOS 10.3.3
Airplane Mode On
Max Height 500m
Total Distance 9688.2m
Flight Time 16:22
I also recorded 4k the whole way.
Zero issues.
PS I had Low battery warning set to 30% so it called it back very early. It his exactly 30% when it got back to me so I could have gone quite a bit further.
