Here's what Candy Crush Saga and Kim Kardashian are doing to your phone's storage and battery life

Kim Kardashian doesn’t look like she works very hard in her reality show, but her game is definitely making your phone sweat.

Some of today’s top mobile games don’t make millions of dollars by going easy on your smartphone and tablet hardware. In fact, they are often one of the biggest drains on the performance of iOS and Android devices, according to utility developer Cheetah Mobile. Games like Bejeweled and Candy Crush Saga require ample storage space and a ton of memory when running. That can cause your battery to poop out much faster than if you were just using your iPhone to text or send email.
