For years iPhone users have been swiping to close apps after each use, in a bid to maintain a healthy battery life.
Whilst it seems like common sense to close apps that we aren't using, it can actually damage our phone's performance over time, it's claimed.
The apps that are shown in the carousel aren't actually running, they're temporarily frozen.
Which means they're not draining your battery whilst you do other things.
Apple experts say you only need to close an app if it is frozen and is completely unresponsive.
They explain: "When your recently used apps appear, the apps aren’t open, but they're in standby mode to help you navigate and multitask.
"You should force an app to close only if it’s unresponsive".
But, part of the issue may be that due to the speed at which apps load after they're selected from the carousel, users assume they haven't stopped running, hence, draining the battery – but they're not.
CJ Phillips for ConnectItCompany said: "When you quit an app, it unloads the app from the RAM (short term memory), and when you need it again it has to load it from scratch. All of that unloading and reloading causes more drain than simply letting the iOS system do it for you."
Simply, reloading apps requires more power than when they're left in standby mode.
