However as it turns out, it is completely unnecessary. According to a report from 9to5Mac, they have managed to get their hands on an email sent by an iOS user to Tim Cook, asking him if quitting iOS multitasking apps is necessary and if it might have any kind of impact on the phone’s performance or battery life.
While Cook did not reply, Apple’s iOS chief Craig Federighi did and in his reply, his answer was basically no, it does not matter. While he did not dive into the details, Federighi answered by saying no to both of the user’s questions regarding whether or not he closes apps often, and if it impacts battery life.
In fact Federighi’s response is similar to what we have heard back in 2014, in which a former Apple Genius said that quitting apps could lead to battery drain simply because the apps are taken out of the phone’s memory, and that by having to relaunch them, it will actually consume more battery, but hey if it puts your mind at ease, more power to you.
