Electronics tend to like it around 15 degrees celsius ambient air temperature. They start failing above 50 degrees and below 5 degrees. Military grade electronics can be made to work down to -10 degrees but the temperature at 20km is around -30 degrees. Also, stuff like your iPhone and Arduino (the most common hobbyist UAV platform) are not military grade.
