Facebook is one of the applications that consumes a lot of battery power even when you don't use it, and yesterday a hallucinatory explanation was offered for how the application consumes an extremely large amount of battery when theoretically it shouldn't.
Although Facebook application is closed by users and left in the background, where it should not generate traffic, especially when the Background App Refresh system is disabled, the reality is completely different from what you imagine.
More precisely, it seems the Facebook application abuses certain APIs for VOIP in the background and audio in the background, through techniques of this kind the application continues to function even when it should be completely closed without generating activity in the background.
Everything seems to be related to the video clips displayed by Facebook in the News Feed, the Facebook company abusing the APIs for background audio to keep the application active even when it is closed in the background, such practices being theoretically prohibited by Apple.
How does Facebook do everything? Well the Facebook application automatically plays video clips with the volume set to minimum when it is closed in the background, the video clips being played when users surf the Internet using Wi-Fi connections, but also when they use a cellular connection.
The good part is that Facebook can only automatically play the video clips on the main screen of the application when we use it, so theoretically we are talking about reduced activity in the background, until we open the application again and a video clip is automatically started again.
My guess is that Facebook is hijacking audio sessions on iOS by keeping silent audio in the background whenever a video plays in the app. And because, by default, videos on Facebook auto-play on both Wi-Fi and Cellular and few people ever bother to turn it off, that means there's a high chance the Facebook app will always find a way to play a video, keep audio in the background, and consume energy to perform background tasks.
The worst part is that including additional cellular data consumption without Facebook to pay him and that's how Facebook surpassed YouTube in the number of views for video clips, stealing and cheating to get what it needs.
What Facebook is doing violates all Apple rules, but unfortunately those from Cupertino do not stop such practices and we are left without battery in our terminals. The solution to this problem is not to delete the Facebook application, but to disable the automatic playback of video clips.
Here I told you how to stop the automatic playback of video clips in the Facebook application and theoretically you should improve your battery autonomy, my recommendation is to completely close the Facebook application in the background when you are not using it.
