Even when Facebook's application released for iOS sets background update off, it continues to update against the user's intention and as a resultConsumes a lot of batteriesIt turned out that it was doing. Karakuri is to constantly reproduce silent sound so that the application is in a running state and it is known that it can be taken as a "workmanship" behind the so-called system .

First of all, Matt Galligan who discovered an unusual battery consumption of the Facebook application, has released its details in a blog published on Medium of the blog platform.

According to the blog, when I surveyed from the fact that I noticed that the Facebook application's battery usage rate is unusually high, I have said that "the workmanship" as mentioned above was found. Mr. Galligan's iPhone 6s Plus accounted for 15% of the consumption in the last 7 days despite having set the Facebook application to "off" in the "Background update" item on the setting screen It turned out.


Galligan's blog posted the following points. Mr. Galligan is casting doubts on too cryptic circumstances.

· In the last seven days, Facebook app was the most consuming application of your iPhone 6 Plus battery
· The consumption is actually as much as 15%.
· Even though the background update was turned off, even though the home button was pressed, the application was not actually in the "sleep state", so it was always in a condition to consume the battery
· Especially when I did not give benefit to me, the applicationIt was twice longer actually than the time I actually used itIs supposed to
Even battery-eating apps like Safari show 3 points less consumption than Facebook apps. This is actually 30 minutes longer than the Facebook app actually used for me.

In response to this announcement, Nick Heer, who is also a developer himself, has disclosed the cause of the phenomenon in his blog and points out that it is "abusing" functions provided in iOS.

According to Heer, the Facebook appVOIP backgrounding,Audio backgrounding,Content-available push notificationsIt is said that the application is always in operation state by combining any of the functions of the application. In the following tweets, a screen showing that the Facebook application consumes the battery using the "Audio (voice)" function is released.

Heer further said, "Do not get me wrong.This is a hostile act against the user.Facebook is making its own way to direct the application to keep updating contrary to the user's intention.Ironi- cally, batteries The best way to reduce consumption is to turn on background updating, or uninstall the Facebook application and check out the application that Facebook also releasesPaper"I will transfer to Japan (not provided in Japan)" I have criticized it severely.

In addition, Federico Viticci who operates a Mac related blog "MacStories" guessed a concrete method. Viticci says, "Perhaps the Facebook app is hijacking (misuse) the iOS audio session by playing silent sound, because in the Facebook application installed on my iPhone, Wi - Since the auto play of video is turned off even in the Fi environment or the state of the mobile phone network, it seems that the Facebook application is very likely to play video and sound in the background in some way "The details are clarified.

Following these indications, Facebook announced correspondence. A Facebook spokesperson told TechCrunch that Facebook has confirmed the facts, said it is investigating details, and said it will release a modified version "in the near future."

As it were, as evidenced by these blogs is "circumstantial evidence", it is appropriate at the present time that Facebook can not conclude that such behavior was intentionally incorporated with malice. It seems likely to be said that it is a judgment. Nevertheless, it is clear from the situation that the application is performing against the intention of the user, and it is not always preferable that valuable battery capacity be consumed as a gang, so take some measures It is inevitable that Facebook does it.

In addition to this, since the Facebook application has not released its contents on the App Store etc. at the time of software update, it is in a state where it can hardly grasp what kind of change is actually made, so in the future Since it is unknown which version to release from which version it is normal, as a countermeasure that can be done immediately to avoid battery consumption, "uninstall application and use Facebook from browser" is the best choice It is.
