Facebook apologises for iPhone battery drain issues, releases partial fix.

Facebook has apologised for bugs in its app which ate up users’ iPhone battery power even when they weren’t actively using the app, and has released what appears to be a partial fix in an update.iOS users have been struggling with poor battery life on their devices for a long time now, and one of the main culprits has been Facebook’s official app.

Last week, several stories circulated about users’ Facebook apps were clocking up absurd amounts of “background activity” relative to how much screen time they actually spent with the app, with many theories floating around as to why. In his post, he detailed the two main issues: a “CPU spin” in the network code causing repeated processing and a problem with audio session management, when the audio remained running silently in the background.

This background activity is the kind of thing that, say, a radio streaming app would register while you’re listening to audio, but not spending active screen time in the app. While the update to the app claims “some improvements that should start making this better”, Facebook is not guaranteeing that it will improve phone battery usage. The second issue he pinpointed was “CPU spin” in the app’s network code – which works kind of like a never-ending feedback loop so the app is never really sleeping. “A CPU spin is like a child in a car asking, ‘Are we there yet?

Facebook came under scrutiny for similar reasons in April last year, when a former Apple expert discovered the Facebook app was continually requesting resources, hogging battery power as a result. • Set your phone to low power mode. This Apple iOS 9 feature will temporarily reduce power consumption by either reducing or turning off a bunch of non-crucial features, like Siri and automatic downloads.
