If You Uninstall This One App, It Makes Your iPhone Last 15% Longer

Here’s the good news - if you uninstall just one app, it can boost your iPhone’s battery life by as much as 15%.

Now the bad news: the app you have to uninstall is Facebook.

You don’t have to stop using the social network altogether - you just switch to browsing it via the Safari web browser instead of the app.

Last year, people complained that Facebook’s app drained iPhone’s batteries by remaining active even when not in use - and tests on Android phones showed the app drained batteries.

Tests by tech writer Samuel Gibbs, writing for the Guardian, show that exactly the same is true for iPhone.

Gibbs says, ‘Using an iPhone 6S Plus for a week without the main Facebook app installed, I recorded the battery life at 10.30pm each day for a week comparing it to a daily average taken from a week with the app.

‘I discovered that uninstalling Facebook’s iOS app and switching to Safari can save up to 15% of iPhone battery life.

On Android, the app is even more power-hungry.

Many report that battery life goes up by 20% just from removing the app, and there are lots of anecdotal reports of boosted speeds, too.

The good news is that (on Android at least) Facebook Messenger isn’t quite so bad - so if you DO decide to ditch the main app, you can run Messenger, and just stay logged in to Facebook on Chrome.
