How will your phone battery hold up in the cold?

(FOX 9) - If you enter these frigid temperatures with a fully-charged phone battery, it might not last long. 

As FOX 9 Chief Meteorologist Ian Leonard shows, less than two minutes in temperatures like these can kill your phone even if it was fully charged. 

Phones are our lifelines in case of emergency, but in temperatures as low as 30 below zero, you can't count on them if you leave them out in the cold.
