Facebook today began to update for the iPhone Facebook app to fix a battery drain issue that the company touted last week, Ari Grant, a Facebook engineer, said: “We found a few key issues and have identified additional improvements, some of which are in the version of the app that was released today.”
The first issue lies in the networking code, “CPU spin is like a child in a car constantly asking” “Are we there yet? Are we there yet? Are we there yet?” with the question not resulting in any progress to reaching the destination. This repeated processing causes our app to use more battery than intended. The version released today has some improvements that should start making this better.
The second issue lies in the audio. ” If you leave the Facebook app after watching a video, the audio session sometimes stays open as if the app was playing audio silently.” and thereby draining more battery.
Grant also asserted that the other issues we have found are not caused by the optional Location History feature in the Facebook app or anything related to location. In the end they also said “We are committed to continuing to improve the battery usage of our app and you should see improvements in the version released today.”
