Here's a screen-cap published by Apple blog, 9to5mac.com:
Though he didn't receive a reply from Cook, he did get a response from Senior Vice President Craig Federighi, who answered: "No and No."
A more detailed response was provided by former Apple technician and CEO of software company MartianCraft, Kyle Ritcher.
He said: "Force-quitting suspended apps will under most circumstances drain your battery faster than simply waiting for the user to return."
Quitting the apps you use all the time is even harder on your battery.
"The very process of quitting an app will use up a measurable amount of battery life." He continues: "This is doubly true for any app that you are frequently launching and using, these apps in all likelihood will never need to be closed and the repetitive exiting and relaunching can have a very noticeable toll on your battery life."
So there you have it bros. Stop killing those apps every now and then because it makes no sense...unless the sheer thought of all those apps opened simultaneously on your gadget keeps you awake all night.
