So I have iOS 9.2 and the latest firmware on the bird and version of the DJI Go app. Today me and my brother went out for a flight. Tested the new version at home first, everything seemed fine. When we got down to the beach I plugged my device in and suddenly my iPhone 6+ rebooted and told me I had to plug inn a charger. So I though I maybe had not had 50% of battery left after all. So we downloaded the app on my brothers iPhone 6+ with 9.2 also.. he had 54% battery left. after 6 mins of flying, his phone also booted and went into "need to charge mode". So I landed manually and went home. When I stuck my phone in the charger and booted it said 32%. My brother also had juice left. 40%.. Its a couple of minus degrees here, not to low. When I flew a month a go with iOS 9.1 in -4 there where no problems.. so I guess there is a problem with iOS 9.2?? anybody else have this issue?
