Even if Facebook's application for iOS turned off in the backgroundConsumes a lot of batteriesWhat has been made clear from reports by multiple users, but Facebook has officially approved and sold the latest version of the application about battery problems.

Ari Grant, the engineer manager for the Facebook application for iOS, said that the application development team reviewed the battery consumption problem of the Facebook application in response to many users reporting.

According to Mr. Grant, the reason why the application wastefully consuming the iPhone's battery is twofold, the first being "CPU spin" in the network code, than by assuming that processing is constantly requested from the CPU The battery consumption was getting higher.

The second problem is related to the sound pointed out by the user's report. When playing a movie in the Facebook application, the function "Audio Session" which controls the operation of audio within the iOS device may remain on even after the movie is ended, and the movie is being played silently It is said that it will be in the same state. Although it does not actually sound, it seems that it consumed the same battery as opening music app in the background and keeping music running. Version 42.0 has been fixed so that it does not play videos and music in the background.
