4. Delete the Facebook App
If you’re like the majority of people, you’re probably on Facebook, and you probably have the Facebook app downloaded to your iPhone. But while the social media app is a handy way to keep in touch, it can also wreak havoc on your iPhone’s battery by auto-loading /auto-playing videos and continuously searching for your location. If you’re willing to trade a little bit of convenience for top-notch battery performance, one of the simplest ways is to delete the Facebook app, and use iPhone’s web browser to log onto Facebook instead.
Pro-Tip: Add a Safari shortcut to Facebook on your Home Screen for easy access. When browsing Facebook.com, just tap the Share icon, and then tap Add to Home Screen.
