The Facebook App
Even when you aren’t using the Facebook app, it is working overtime by tracking your location and even storing info about the browser pages that you visit so that it can serve you targeted apps. Of all of the apps you use, Facebook is, by far, one of the most draining.
Flicking away apps doesn’t generally help with battery power — but one expert at Cult of Mac explains how the Facebook app is an exception to this rule:
“… I realized that flicking away the Facebook app did impact my battery in a positive way, since doing so meant it wasn’t able to run in the background (despite Background App Refresh being set to off).”
In addition to flicking away Facebook, there are a few more steps you can take to minimize the damage this app has on your battery.
For starters, turn off Background App Refresh: go to Settings > Facebook > Settings > Location Services > and then set it to Never.
Another good tip: stop Facebook from autoplaying videos by launching the Facebook app and then tapping at More on the bottom. From here, choose Settings > Account Settings > Videos and Photos > set Autoplay to Never Autoplay Videos.
And remember: all apps that track your location have the power to run down your battery. While you’re flicking away Facebook, flick away navigation apps to avoid extra battery drainage.
