Verizon Galaxy S4: 1013 System and battery drain.
Recently my wife's S4 started draining the battery a lot faster than usual. I installed Battery Monitor and Wakelock Detector and it took a few days to figure out what was going on.
The Battery Monitor app show 28 distinct batter drains. About 2-3 per hour. I cross checked with Wakelock Detector and found that the 1013 system had 28 hits. So I opened it up and the "AudioOut_2" was on for 50 seconds and had 16 hits. Although it's not a crisis battery draw it is substantially more than usual. She use to end the day with 80%+ battery left over and now she ends up with 30%. She is definitely not a power user LOL. She just uses the phone and text and the occasional browser search.
So what is the AudioOut_2 connected to? What is the app or program that uses this. She doesn't play any music on her phone.
