Facebook acknowledges battery issues with iOS app

facebook-search-update-011

You’re not seeing things: Facebook’s app for iOS 9 really is draining your iPhone’s battery, and at an alarming rate. Luckily, Facebook knows there’s a problem, and says a fix is on the way.

Facebook’s Ari Grant acknowledged the problem in a Facebook post on Thursday, explaining what’s causing the app to suck so much battery.

“The first issue we found was a “CPU spin” in our network code,” Grant said. “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. This repeated processing causes our app to use more battery than intended. The version released today has some improvements that should start making this better.”

Grant also said there was a quirk regarding video playback, explaining that when someone watched a video and left the app, the session sometimes stayed open as though audio were still playing. The feature is a lot like a music application being closed but continuing to play music in the background. The only problem was the Facebook app wasn’t doing anything, causing your iPhone’s battery to drain.

“The issues we have found are not caused by the optional Location History feature in the Facebook app or anything related to location,” Grant said.

So now you know why Facebook is so hungry for battery life on iOS. The good news is things should be back to normal soon after a few more bugs are squashed.
