Well summer is upon us again here in the South West with its heat, and it heats up quick! My iPhone 6+ keeps shutting down while I'm in the middle of flying around. I use a sun hood but it keeps saying operating temp is to hot or something like that and turns off. I end up just bringing the drone back for a landing and try to cool the phone down with the cars AC. Still a pain and tried different times of the day as well. Also my ipad mini does the same thing.
