Facebook is draining your iPhone’s battery

Users of the Facebook app have experienced huge loss of battery levels even when not using the app.

It’s been reported that this is due to the app running in the background, even when setting background refresh off. The cause of the battery drainage was discovered and explained by Facebook’s Ari Grant.

“The first issue we found was a ‘CPU spin’ in our network code,” Grant said in a post.

“A CPU spin is like a child in a car asking, ‘Are we there yet? Are we there yet? Are we there yet?’ with the question not resulting in any progress to reaching the destination,” he explain, adding that this repeated processing was causes the app to use more battery.

A second issue was also discovered that Grant also addressed.

“If you leave the Facebook app after watching a video, the audio session sometimes stays open as if the app was playing audio silently,” Grant said. This is similar to when you close a music app and want to keep listening to the music while you do other things, except in this case it was unintentional and nothing kept playing.” Facebook’s app isn’t actually doing anything in this state, but draining battery in the background
