Lately I have noticed an unusual drain in my battery. After identifying the cause with BBS I found it to be a wakelock related to audio. I went thru my apps that could potentially cause the problem, I didn't find any.
Do you know what the problem was? It was a problem with my notifications muted.
When you select volume for the ringer / system / media etc. When you mute the 'Notifications' you will get a nasty wakelock that won't disappear until you increase the volume a bit at least.
Just thought I'd let you guys know. Also I have noticed the same wakelock when I had my I9300 S3.
