7) “The reason why digital devices are so vulnerable to the cold is the battery,” said Doctor Lee Jin-ho of the Electronics and Telecommunications Research Institute.

8) Most digital devices are equipped with lithium-ion batteries. These batteries produce power and operate devices using a chemical reaction from liquid electrodes.

9) In sub-zero temperatures, liquid electrodes freeze and power goes down temporarily. If left in this state, battery life is rapidly reduced.

10) Doctor Lee says that you would only be able to use 10 percent of a 100 percent charged battery in minus 20 Celsius.

11) When a smartphone or a camera dies in the cold, it is unwise to move it somewhere hot and humid and turn it back on right away.

12) If you turn on the power when dew is gathered on the surface of a cold electronic circuit, it can cause a short-circuit failure.

13) Rather, wait about five minutes before you turn your device on in a warmer place.

14) These sensitive phones may need new coats for the winter.
