If your iPhone’s battery life seems to be going the way of the dodo, the Facebook app might be to blame.
Per Cult of Mac, the iOS developer behind Home Remind has published a blog post about the Facebook apps for iPhone, iPad and Facebook Messenger. He says that according to his testing, the Facebook apps consume way more CPU time than is strictly necessary. Excessive CPU time can lead to battery drain.
The developer used Apple’s own Mac-based app, Instruments, to look at what was running on his iPhone, and found that his Facebook app was activating, doing something for ten seconds, then going back to sleep. It did this all day long during his test. He tested the Messenger app and the Facebook iPad app, and found the same pattern.
If that’s the case, the Facebook app is never truly going to sleep and then terminating like a good app. As a result, it’s using up CPU time, and a lot of your battery.
According to the blog post, Facebook is able to do this because it meets the criteria for two types of apps that Apple allows to run in the background: audio apps and voice over IP apps. Facebook apps are operating under these two backgrounding apps privileges, and, as such, are actively chewing up your battery time.
The developer doesn’t say that Facebook is doing this on purpose, and it hoping to make the company aware of the problem, so that they could possibly fix it in an update. Until then, he says, there are only two options.
You can delete the Facebook apps from your iPhone or iPad, and then just use the web version of Facebook, or you can force-quit the app when you’re not using it by double clicking the home button, tapping and holding the Facebook icon in the multitasking bar, and then tapping the little red minus icon. That way, he says, Facebook apps will well and truly be terminated.
If you’ve seen this battery drain on your end or have two cents to throw in on the issue, please let us know in the comments.
