It is believed closing background apps in the iPhone will save battery power, but head of Apple's operating system iOS, Craig Federighi, confirmed this is not the case.

The rumours were put to bed when an iPhone user asked Apple's CEO Tim Cook in an email whether multitasking apps should be shut down to save battery life.

According to blog 9to5Mac, the customer asked: "Do you quit your iOS multitasking apps frequently and is this necessary for battery life?"

Federighi simply replied "no and no", along with a smiley face.
In fact, most apps are suspended when they are sent to the background and if the user re-opens the app, it comes back from its frozen state, meaning they remain dormant until the user uses it again. However some apps, such as music apps or GPS navigator apps, will continue to run in the background. These are the recommended apps which require to be shut down.

9to5Mac reporter Benjamin Mayo said: "Quitting all your apps is clearly not supposed to be a thing, as it involves laboriously swiping up on tens to hundreds of individual app windows in the multitasking view. On a technical level, most of the apps are either frozen in RAM or not running at all, the system just displays them as a history for consistency. This is why the battery life impact is negligible."

However, other smartphones such as the Nokia Lumia and the Galaxy 6, benefit from app closure.
