Facebook acknowledged this problem and partly fixed it.
However, the solution doesn’t seem to be satisfactory.
Ari Grant of Facebook offered two reasons for the problem: a CPU spin and poor audio sessions management.
A CPU spin is a complex mechanism.
TheCPUis the microprocessor of your smartphone.
It services (runs) threads, which are tasks to be executed by running programs or apps.
This is a CPU spin, which consumes battery power and other resources affecting performance and battery life.
It is suspected that there are other problems related to the app running in the background.
Like the audio, several other parameters might have been poorly managed.
It could be that inefficient management of the Facebook app causes inefficiencies with those other apps.
It will work just like on your box.
