Facebook fixed its app for iPhones. It came as a relief for all the people who had been waiting on the bug fix. Imagine that smartphones are not exactly your battery friendly type of gadgets. Even with casual use, we still have to recharge every smartphone on a regular basis, iPhones included. But what do you do when you see that your Facebook app drains the life out of your gadget? You got to Facebook and report it, of course.

Not only did Facebook deal with their gone astray app, but they also reached out to the community in a post, explaining what the sources of the issue were and thanking all the users for their patience and willingness to improve the experience rather than just letting it dry out. The truth is that it can be extremely difficult to cope with such an issue, especially since Facebook is the most used social media app at the moment.

The two issues were a “CPU spin” and sound sessions that were not appropriately turned off. We are going to explain each issue in turn, so that you know exactly what you were up against.

The CPU spin was compared by a Facebook representative to a child asking if it arrived at the destination multiple times. Imagine a marathon runner who was to run 10,000 miles and he is wasting his energy on wondering when he will arrive rather than on the journey itself. The CPU was practically tiring itself for no reason and it was killing the battery while “wondering” where it was going.

The sound session was something else entirely. You do watch videos on Facebook from time to time, right? Well whenever you open a video, you open a sound session as well and the sound session is consuming resources for it to work. The problem with the Facebook app was that, even if you stopped watching the video and closed the app entirely, the sound session would still be active, thus wasting your resources for no reason.

Facebook fixed its app for iPhones now and everything seems to look ok. The company has also declared that there was no virus or intentional misuse of the app, but just these two issues that were rendering batteries useless. It is also very important that Facebook communicated with the community during the problem, showing that they are interested in getting things done. If they had just sit silently without saying anything, even if they had released the bug fix, the response would not have been a good one.
