If you thought your cell phone, laptop or other electronics were draining faster than usual during the unusual bitter cold, you’re not wrong.

Electronic experts say the bitter cold drains batteries faster so people who depend on their cell phones in remote locations need to make sure they recharge often and have chargers in their car in the event of an emergency.

One computer expert said that Apple computers are especially vulnerable to the cold.

“Apple is rated from I believe 32 degrees to roughly 95 degrees,” David Greer of Digital Doc told CBS. “Samsung is rated from minus, negative 4 to up to 128.”

Greer also warned of the importance of not trying to rapidly heat your phone or computer if it’s cold. Greer said you risk major damage to the devices if you do not allow them to slowly reach room temperature.

He suggests making sure you keep your phone in a jacket or close to your body to keep it warm.
