If you own an iPhone, you are wasting your time whenever you swipe to close iOS apps.
You probably think that by closing the apps you are saving on battery and processing power.
However, this is nothing more than a myth and swiping to close iOS apps does almost nothing to improve battery power.
In fact, it may actually be detrimental to the overall performance of your iPhone, experts have warned.
The idea that force closing iPhone apps, which is done by double tapping the Home button and then swiping left on the app preview, saves battery power has been long been a topic of debate among iPhone users.
The function to force close apps is there to shut down an app if it has crashed or isn’t working properly. But claims that it also helps to improve battery life are false.
Now renowned Apple expert John Gruber hopes to end the debate once and for all.
Writing on the Daring Fireball blog, Gruber says because of the way iOS has been designed, there is no need to close apps that are running in the background.
“The iOS system is designed so that none of the above justifications for force quitting are true,” Gruber wrote in a blog post.
“Apps in the background are effectively “frozen”, severely limiting what they can do in the background and freeing up the RAM they were using. iOS is really, really good at this.
“It is so good at this that unfreezing a frozen app takes up way less CPU (and energy) than relaunching an app that had been force quit. Not only does force quitting your apps not help, it actually hurts.
“Your battery life will be worse and it will take much longer to switch apps if you force quit apps in the background.”
Whenever you swipe to close an app, your iPhone then needs to open the app from scratch the next time you want to use it, which is more power intensive than just resuming the app from its frozen state.
This isn’t the first time Apple users have been told there is no need to force close apps.
Last year, Apple’s most senior iOS executive Craig Federighi answered an email from an Apple customer on this very subject.
When asked if it was helpful to swipe to close apps to save battery power, Mr Federighi replied simply “no and no.”
