iPhone users who have been suffering from worse battery life since upgrading to iOS 9 may want to try deleting Facebook’s iOS app.
The social network confirmed reports that surfaced earlier this week claiming the iOS app uses a heavy amount of resources in the background to run processes. The big problem with the battery drain is that it occurs even if iPhone owners have background app refresh disabled. It’s actually worse with the setting turned off. because Facebook is sneakily creating channels to continue refreshing its app in the background, even when users tell it not to.
