Here's how you can extend your iPhone's battery life

Uninstalling the Facebook app from your iPhone can save up to 15% of your battery life, a new test found.

One of the most downloaded apps on iOS, Facebook has long been cited as a cause of fast-draining iPhone batteries. The secret to maintaining up to 15% of your battery? Uninstall the app.



In 2015, the app was accused of using background tricks to stay active even when it wasn't being used. Although Facebook admitted that bugs existed and claimed to have fixed them, questions of the apps impact on battery life remained.

Similar concerns about Facebook's Android app led to the discovery that deleting the app saves up to 20% of a phone's battery. Following the revelation, a user set about seeing if the same was true for iPhone users.

To ensure the test was valid, several other Facebook-using iPhone owners conducted the test. They all uninstalled the app and switched to the Safari browser and all found similar results; such that deleting the app saves up to 20% of a phone's battery life.



After uninstalling the app, users browsed Facebook for the same amount of time on Facebook's mobile app for Safari and charged their phones overnight.

Users found that using Facebook on Safari was just as good as using the app, although, the share-to function was not available without the app. Further, features of the app, such as Instant Articles, are also not available. Tapping a link on the Facebook mobile site opens a new Safari tab.

Many took to Twitter sharing the news.

I have uninstalled the FaceBook app from my iPad 2 and it works much better now. I can still easily access FB... https://t.co/eygBeDsw5e

@sprest11 uninstall & then install Metal a wrapper app linked to FB & you get the best of both worlds. I did this earlier & will see 😊

Really happy to see the "uninstall FB app and use the mobile site" advice spreading in my non-tech circles. Hopefully a sign of the times.

Apparently, you can save 15 to 20% battery life if you uninstall the FB App from your iOS or Android phone. Use the web version instead :)
