PITTSBURGH (KDKA) – More than ever, people are relying on their smartphones to make calls, text, and use the internet.

In fact, statistics show more than 70 percent of cell phone users turn to their devices for help in an emergency.

So, it’s important to make sure your phone is in good working order and that can be tough to do during a deep freeze.

If you’re heading out in the bitter cold this weekend, there are simple steps you can take to keep your phone protected.

The key is keeping your phone warm. Smartphones were developed to function above 32-degrees.

“I just keep it in my pocket, it’s too cold to play with,” said Sarah Youngblood of Brentwood.

Thats what you should do. If you’re outside, keep your phone in your pocket, rather than in a purse or other bag. Your body heat will help. A pocket closest to your body is best. Another tip? Take a good look at your case.

“I do have a decent case, but its not heavy duty, so its not as protected as it could be I’m sure,” said Jessica Mellors of Greensburg.

If you’re out in the snow, a heavy duty waterproof case can help keep your phone operating, especially long term. Plus, a heavier material means more insulation.

Don’t forget your screen. Extreme temperatures can cause your smartphone’s screen to crack.

When it comes to battery life, the cold can be a real killer. An extra battery pack is a good idea. If nothing else, keep a car charger close by if you’re traveling in winter weather.

“I have noticed that the cold has been affecting my smartphone when I go walking around the park, it will die at like 60 percent,” said Spencer Huff.
