I'm also facing this issue. Do you guys use PowerAMP to listen to music? I don't know why I think at PowerAMP, but I've had this issue also with my old Nexus 5 (now I'm on a OnePlus ONE), and NEVER found a solution. I really don't know what to do. That's even more strange thinking that some days ago I did not noticed this problem, now apparently random it started draining battery..
Ok just tried with some basic tests:
tried disabling sound at pressure on screen and lockscreen sound, checking with BBB it seems it's stopped now. Also it seems to stop using vibration instead sounds. Every time the phone emits a sound (coming from a pressure on the screen, such as the BBB refresh button, or any other sound) this wakelock happens for about 3-4 seconds, then, keeping refreshing BBB statistics it seems to stop. With vibration mode and without sound at pressure on screen this wakelock seems to be ok. But if I turn on the sound checking every checkbox in Audio settings, every time I refresh with BBB the phone emits a sound, and in fact this wakelock never ends and keeps going.
Now what I'm asking is why this happens randomly to someone and why some others don't face this problem. Also because for me started 2-3 days ago, but I always checked every checkbox in Audio Settings.
