Apple VP: Force Quitting iOS Apps Has No Impact on Battery Life


Many iOS users (I’ve witnessed a few around me) have grown into a habit of quitting all their background apps in multitasking view frequently, hoping that it would improve the battery life and speed of their iPhone or iPad. To confirm if this actually has any advantage, a user by the name of Caleb sent an email to Tim Cook asking whether he quits all his apps and if this has any impact on performance (via 9to5Mac).

The guy was lucky enough to get a reply from Apple iOS chief Craig Federighi, whose short but succinct reply was ‘No and No’… After answering the question, he thanks Caleb for being an Apple customer. Below is his email reply, which has been verified by the source for legitimacy:

So there you have it, a simple understanding of how iOS multitasking works shows it is completely unnecessary to close every app in the multitasking view, which we’ve all heard before.

    I’ll keep closing all but my 3 most used ones (and the stupid Pebble app), but just because I’m a bit obsessive about keeping things tidy.

  • I remember the same thing was ask several times on Android as well. The answer Google developers gave was closing all of them can actually decrease your battery life.
    Once you close, the app has to load up all over again, rather loading from a sleep state or cached position. I would think the same would apply to our iPhones, but that’s only a theory.

    For most apps this is correct, But how about the infamous Facebook app? Even with background app refresh turned off, if I don’t close out Facebook there is background time being reported.

  • Force quitting your apps can actually decrease battery life. When you leave an app open in the background it saves its state, so that when you come back to it it can pick up from where you left off. When you force quit it, it has to reload the whole app the next time you open it, so this uses more battery life than just switching back to the saved state. (Now granted, it can only keep doing this for a limited number of “open” apps, but even if the saved state expires, you’re no worse off than if you had force quit the app.)

    Of course, every now and then there is a misbehaving app, and yes, closing those down is a good thing, but unless you’re experiencing higher than normal battery drain or an unusually warm iPhone when you haven’t been using it recently, don’t bother force quitting your apps.

  • Yes, I’ve heard the same thing about iPhones. It makes sense to me. Sorry, I didn’t see your comment before I posted something very similar.

  • Hey, no worries. I don’t always read all the comments either 😛
