Facebook is draining your iPhone battery
That's right - the app is ravaging your juice, and Facebook have said that they hope to fix the problem 'soon', according to TechCrunch. The problem is that the iOS app is running in the background, and it is killing your battery while it does it.
The spokesperson from Facebook said: "We have heard reports of some people experiencing battery issues with our iOS app. We’re looking into this and hope to have a fix in place soon."
If you're thinking that the battery drain will stop if you disable the background app refresh feature? No dice. It'll still drain your phone.
Facebook aren't forthcoming when it comes to saying why this is happening, but they will get 'round to fixing it 'soon', which sounds like 'when we can be arsed' to Bitterwallet.
So, what can you do to stop this from happening in the meantime? Well, there's no clever workaround for this problem - the advice we've got is that you should delete the app. That's the only thing that'll do it. You'll still have your Messenger app, so you won't miss any messages from pals. Until then, get rid.
