Greece is a hot place, namely in summer. Leaving the iPhone out in the sun earlier today, the device stopped working at over 50 Degrees Celsius.
OK, let’s cool it down I thought putting it into the freezer …where I forgot it promptly.
3 Hours later at -25 Degrees, the iPhone did not show any sign of life anymore the device being supposed to function between 0 and 40 degrees Celsius.
After an hour at room ambient temperature (35 degrees) the device started working again … perfectly :-).
