For a certain sort of smartphone user, closing apps becomes almost automatic. You double-tap the home button on your iPhone or hit the multitasking key on your Android, and you just start swiping. You close all the apps you've been using. Days, weeks, months' worth. Not only is there something deeply cathartic about it, but it feels like a cleansing, a reset. Best of all, with no apps running, your battery's in great shape! Right?
Wrong. In the last week or so, both Apple and Google have confirmed that closing your apps does absolutely nothing to improve your battery life. In fact, says Hiroshi Lockheimer, the VP of Engineering for Android, it might make things worse.
