What were the temps? If it was below 24 degrees F you can be sure the iPhone contributed to the issue. Iphone's and some other smart phones do not handle cold well, especially outside the safety of pockets etc. Google IPhone cold rapid battery drain. I have a 6S plus had 100% charge took it out in 10F weather and after five minutes said battery was dead. Warmed up inside for 10 minutes, hit power button and back on at 97%, recreated the again without the DJIgo app even running.
If you google around, People have done tests to see at what temp different smartphones fail, and they were reliably able to make the iPhone battery appear drained when exposing it to temps below 24*. These tests were general cold weather tests and were not related to DJIgo app, but I believe shows there existing issue with the iPhone, that may or may not be exaggerated by the intensive processing that the GO app requires.
edit: I also tried the mini 2, which held up longer but also would crash in extreme cold. Plus common sense tells me an ipad with Larger screen (light source) Larger batter (power source) probably will retain its heat longer than a small device.
Not to sound like a jerk, but you can't really fault DJI for this happening if it happens when you are operating outside of the stated safe operating temp by DJI (Not saying you were but I have a hunch based on my own experiences.)
