Removing this one app could increase your iPhone's battery life by 15%

The Android edition of the official Facebook app was recently confirmed as a major battery hog. The iOS version, however, doesn't appear to be much better, and according to testing carried out by The Guardian newspaper in the UK, the app will eke away precious droplets of juice even when not in use. With a 15 percent improvement after deletion and a switch to the mobile site, the difference is slightly below the 20 percent gains Android users can enjoy by removing the social network's famed app. Still, given that battery preservation is a top priority of smartphone owners far and wide, sacrificing the Facebook app may be an advisable step to all.
