[Q] AudioOut_2 partial wakelock drains my battery

Renecek · Mar 30, 2013

Hello, I know, on XDA is a lot of topics with this problem but I didn't find any solution there.

Some days ago I flashed my device to stock ROM 4.1.2 [XEO]. Of course, I made full wipe before flash and I didn't root my device.

I installed apps which I use and problem is here. I read, Viber is draining battery, so I went to settings of Viber and checked "Use System Sounds" and disabled vibrate when somebody sends me a message.

In android settings I disabled system sounds and vibrate too.

List of my apps:

Code:

AirDroid
Any.DO
Apex Launcher
BetterBatteryStats
Business Calendar
Cerberus
Dolphin Browser
Dropbox
Dropsync
EZ File Browser
Facebook
Feedly
Keep
Messenger (Facebook)
MX Player
PicsArt
SMS Backup & Restore
SoundHound
Swapps
Tapatalk
Tasker
Tinylight
Twitter
Viber
Waze
WeatherPro
WidgetLocker
Zooper Widget Pro

At night, tasker turns my device to airplane mode from 03:00 - 07:30.

Battery is really important for me so I will be really very thankful if somebody helps me to fix my problem with drain.

Here is BetterBatteryStats screen:

Thank you for your answer.

Tip 1:
- doesn't work for me. I wrote to CurrentWidget support. They tell me, problem is with Samsung devices (still shows 0mA)

Tip 2:
- have all disabled / enabled

So I found, I must close all aps before I lock my device or use Advanced Task Killer. I read a lot of articles and they don't recommend use 3rd task killers apps and auto-killing is bad for android. So I don't know what I can do now.

Bs. If you configure it to automatically kill all apps at screen off then nothing is gonna go wrong. I have set it up and everything is good here. Also use greenify to stop apps from running in the background that you don't want.

I just uninstalled Viber, hope, it will fix my problem. / installed Whatsapp

I had this issue, i downloaded installed and ran "Rescan Media Root" from the Google Play Store. Problem solved. Without having to uninstall Whatsapp or Viber etc.

Thanks but I don't have rooted device. Btw still have AudioOut_2 problem.. BetterBatteryStats shows me 15 minutes of AudioOut_2 now..

It is not Viber, despite what many people say on numerous threads.

I uninstalled Viber and the problem is still there.

To this day no one knows what the cause is. There have been many suggestions but no definite answer.

And to make it more difficult to solve, it looks like it's completely random.

I hate this kind of problems, the intermittent ones...

It is due to any app that uses audio. To shortlist it is generally in apps that use audio and continue running in background.
The only solution is to kill all apps before letting it sleep.

Thank you for all replies. Hmmm today I get good stats of battery and AudioOut_2. I don't understand

I can personally confirm that both Viber and Skype (when signed in) cause this wakelock. Also, this wakelock appears regardless of whether you turn off your screen. Play 15 minutes of audio with the screen on, you get this wakelock. Play a game, kill the process, you get this wakelock. It occurs even if you're using the phone, not only during screen off.

Edit: What I meant to say was, Viber and Skype cause this wakelock during screen off time.

Some hours ago I sent some messages via fb messenger and whatsapp, read some topics in tapatalk and read rss via feedly. AudioOut_2 is high again.

Basically an instruction to the CPU that stops it going to deep sleep. But try what I said, set a custom reference in Better Battery Stats, play music for 15 minutes while using the phone. You will get 15 minutes of AudioOut_2.

I have the same findings as you. Get lots of AudioOut_2 wakelock but it actually corresponds to the time i spend playing games with sound on (which obviously happens when screen is on). And even with high amount of this wakelock, i still get my normally great battery life. Hence i conclude this wakelock is wrongly captured, at least for me. :cyclops:

Black Dawg Down · Apr 1, 2013

Getting high audioout_2 while playing music or games or anything else which produces sound is of course normal, it's common sense.

The problem is when you have 8 hours of awake time when you're sleeping due to audioout_2. My battery went down by 11% overnight because of this.

So you want your cpu to go into deep sleep while you are using it?

Just configure advanced task killer and greenify. That's all you'll need.

Hello UtkarshGupta,

so I tried to install Advanced Task Killer and here is my setup:

In settings I checked Ignore service, fron app
Auto Kill Level: Crazy
Auto Kill Frequency: When screen off

I created recommend ignore list and add some apps but I don't know if I can kill for example Clock too.
BTW I see S Suggest and S Voice are runned. I don't know why, coz' I didn't start these apps.

UtkarshGupta · Apr 1, 2013

I don't have any ignore list. In fact I deleted the ones which were pre configured. I don't have any issues.

but i.e. I'm using WidgetLocker or Apex Launcher. If I kill one of these apps, it will be not a good solution.. hm?
