A lot of users noticed a drastic decrease in their battery level after using the Facebook App on their iOS devices. No, your phone is not at fault for this one, it’s Facebook itself. The social networking giant has finally acknowledged the problem and introduced an updated version of the App today.
“The first issue we found was a ‘CPU spin’ in our network code. A CPU spin is like a child in a car 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.” Facebook’s Ari Grant wrote today.
The second issue with the App was the in-App videos, which play automatically. “If you leave the Facebook App after watching a video, the audio session sometimes stays open as if the App was playing audio silently. This is similar to when you close a music App and want to keep listening to the music while you do other things, except in this case it was unintentional and nothing kept playing. The App isn’t actually doing anything while awake in the background, but it does use more battery simply by being awake.” he said.
Grant clarified that none of the issues identified were related to location services. “We are committed to continuing to improve the battery usage of our App and you should see improvements in the version released today,” he wrote. The problem was noticed by some users after installing iOS 9- which shows how long Apps are active and their respective battery consumption.
