Cedar Rapids, IA – According to wireless carriers, it is the lithium-ion batteries in smartphones and other connected devices that often create an issue in cold temperatures. Lithium-ion batteries contain liquid. When extreme cold temperatures are introduced, the molecules shrink, which causes potential issues for displays, buttons and battery life.

“We typically think of hot temperatures causing issues for smart devices, but extreme cold can do the same. Anything below 32 degrees is going to start slowing down your phone,” said Joshua Olbricht, UScellular’s director of sales for east Iowa.

“We use our smart devices for nearly everything these days, so it’s important to keep them protected in extreme temperatures in an effort to maintain their functionality.” With cold temperatures in the forecast, follow these tips to keep your devices safe and working properly:


1.) Charge your device. Because battery power can be reduced in cold temperatures, it’s best to keep your device fully charged to avoid the battery being completely drained in outdoor temperatures. A portable charger is a good thing to carry.

2.) Keep your device in a case. Think about it like a winter jacket. You would not go outside without one, so don’t do that to your phone. When it comes to protecting your phone, a case is a first line of defense. It can create a barrier between your device and the outside elements.


3.) Keep your device in a pocket. Humans are a natural source of heat. When you are out in the cold, try to keep your device in a coat pocket rather than in a purse or bag. This will help protect the device from the shock of the freezing conditions.

4.) Let your device warm up before you try to use it. For optimal performance, users should avoid storing devices in frigid places, such as a parked car. If a phone powers off due to the cold, give it time to warm up to room temperature before you hit the power button. You should never use heating sources, such as a blow dryer.
