It's a simple solution for sure -- you've basically got a teensy icebox in your car -- but it could go a long way in keeping your phone happy and healthy. Prolonged exposure to heat often means bad news for the lithium-ion cells that keep everything running, and really, the last thing a worried driver needs is their phone shutting off mid-navigation because it's suddenly running too hot. Chevy claims they're the first manufacturer to focus on the plight of our nation's hot smartphones, but the answer they've cooked up is so simple we'd be surprised if other car makers didn't take the hint. Until then, though, you'll have to own a 2016 Volt, Cruze, Impala or Malibu with the wireless charging option to stay frosty.
