When the snow, ice, cold and wind are making life miserable, you may have noticed that your phone’s battery drop fast outdoors, especially when you calls or texts outside.
That’s because smartphones are not built for the extreme cold. They have the optimum range of temperatures in their technical specs. For example, the iPhone 5S can withstand temperatures between -4° and 113° Fahrenheit, but Apple suggests 32° Fahrenheit as the lowest operating ambient temperature.
When cold, the lithium-ion battery that exposed to cold temperatures can drain faster than normal, or it might say it has ample power remaining and then suddenly go dead. Of course, the problems are only temporary and the battery should behave normally when the device is brought back up to warmer temperatures. But other delicate electronic parts, like their LCD screens, that can also malfunction in extreme temperatures. Freezing temperatures can also make a phone’s glass surfaces more sensitive to cracks and breaks.
So what can you do to prevent your phone freeze?
First, don’t leave them alone for long in frigid places. Stashing them inside pockets closest to your person, where they can absorb some of your body heat, is best.
Cases also help to keep phones warm. There are even cases especially built to regulate a phone’s temperature in extreme situations.
One last tip: If you’re depending on a phone to make outgoing calls in case of an emergency, keep a portable charger with you — that would allow you to keep your phone charged no matter where you are.
But if your phone does freeze up in the cold, most phones will come back to life. Set it down, leave it warm up to room temperature, and don’t try to shock it.
