One of the most common ways people try to save their iPhone battery doesn’t work

Have you ever tried this?

One of the most common methods iPhone users employ in an effort to save the battery on their iPhone doesn’t actually work, according to a high-ranking Apple official. If you’re an iPhone user, chances are you’ve quit all of the apps in your multitasking feature in an effort to save battery life; it would seem to make perfect sense in fairness. According to Craig Federighi, Apple’s senior vice president of Software Engineering, it doesn’t work at all and though he was a little light on details, he was fairly upfront in his opinion on the matter. Federighi provided a response to an email sent by a reader of influential Apple website 9to5Mac to Apple Ceo Tim Cook inquiring whether he quits his multitasking apps as a method of preserving battery life. Cook didn’t respond, but Federighi did (the e-mail below has been verified by 9to5Mac) with a blunt but unambiguous response. That’s us told.
