Mobile devices, such as smartphones and tablets, don't like cold weather. When a lithium-ion battery is exposed to cold temperatures, it can drain faster than normal or indicate it has ample power remaining and then suddenly go dead. Low temperatures can also make a device's glass surfaces more sensitive to cracks and breaks, especially if there's already a nick.

Here's what to do:

• To keep your device from getting too cold, don't leave it alone for long in frigid places such as a parked car. It's best to stash it inside pockets closest to your person, where it can absorb some of your body heat. 

• In the event your device does shut down, do not restart it until you're inside and have given it time to warm up. Restarting immediately could actually cause more harm and shorten your battery life. 

• Cases also help to keep devices warm. You may want to consider the cases designed to regulate a phone's temperature in extreme weather.

To get specifics for your device, consult the manufacturer's website.
