I thought so, I deleted all my remote apps, (XBMC, Utorrent Remote...) I still got this wakelock, what else could it be? Because my phone drains now at 7% per hour, that's quite high compared to my normal 0,9%.

Have any other network devices gou might not normally use? Maybe a NAS attached to your router? VPN? Remote control app?

Thanks again, guys. I set her to 144 screen off and I stopped getting the mmc_s, but it still could just have been the install settling. Ive made some other changes since then. On TPR 3.10, she got 14 hours of my heaviest use to date, with 4.5 sceen on, 2.1GHz, ktoonservative, row. Felt fast and responsive doing a little bit of everything I ever do on the phone. I'm super happy. Thank you for this informative thread.

Hey guys I have been getting a lot of wlan RX wake lock. Is there any way of finding out using bbs if the cause of this wake lock is due to my WiFi or the kernel I'm using. I really want to get to the cause of this wake lock and possibly fix it if I'm able to. I'm using my schools WiFi so if the problem is WiFi related and not kernel or app related there is very little I can do unfortunately. Any help would be much appreciated:confused:

l2_hsic KWL

Hi folks,

I was under the impression that this forum was purely for developers. I am not a developer so I'm pleased to have just registered on a forum with those in the know.

Right, so just wanted to propose an addition to the list of troublesome KWLs in this thread. I am referring to l2_hsic. This wakelock has come to the fore since updating from Honeycomb to ICS on my Samsung Galaxy Tab 10.1. It prevents my tab entering the deep sleep state for 90% of the time. Battery suffers big time - capacity falls at typically 1.4% per hour even when the display is off and the tab is in airplane mode. Unacceptable. I've read that one possible cure on phones is to disconnect, then reconnect, the battery. Can't do that on my tab. Any other ideas? BTW, my tab is not rooted.

[Android General] T.J. Bender:
Turn Wifi off, reboot, let the phone go. If it's kernel or app level, it's likely to keep going.

I turned WiFi off and rebooted the phone and I'm still getting the wlanrxwake :confused:

bam_dmux_wakelock and GTALK_ASYNC_CONN (AndroidEndpoint)?

Anyone get SMS dispatcher wake lock? There would be times it would drain 5% in 15 minutes screen off and other times would deep sleep just fine. Any fix?
[Android General] T.J. Bender:
Stop your messaging process would be my suggestion. SMS dispatcher controls the sending of text messages.
[Android General] rccar:
That's upsetting because I'm constantly texting around 200 a day
[Android General] T.J. Bender:
That probably has something to do with the wakelock. If there are SMS in queue to be sent when the screen turns off, that wakelock will appear as the process holds the phone awake to send them. Nothing you can do about that.

Most comprehensive wakelock guide I've ever seen, I am going to link to this thread in my Sprint gs3 FAQ thread if you don't mind me doing so! Again, thank you for the guide

Sprint GS3 FAQ THREAD
[Android General] T.J. Bender:
Link to your heart's content. All I ask is an acknowledgement and that others not steal content from this guide and claim it as their own.
[Android General] flastnoles11:
Not a problem, I will make sure I put your username with the link on my FAQ...

Something like T.J. Benders guide to wakelocks as the link work for you? So it would look like this T.J. BENDERS FULL GUIDE TO WAKELOCKS

Don't mean to clutter your thread, any more questions about my FAQ I will send in pm, thanks!
[Android General] T.J. Bender:
I wouldn't call it a "full" guide by any means; there are tons of wakelocks out there, even on the Skyrocket, that I haven't mapped out yet. Start throwing other devices and other manufacturers in there and you'll probably come across hundreds that I've never even seen lol

But yeah, I don't even care if my name's in the link. Just like to make sure credit is given for the work I did here (and may add to in the near future, more on that later). My big thing is not having text copied and pasted out of here into someone else's thread without permission or acknowledgment.

Switched my router to an Asus N66, have been pleasantly surprised by battery life on my Skyrocket instantly improving thanks to wifi related wakelocks dropping under a percent over 1.5 days - that is with wifi never going to sleep and the optimize wifi battery use option turned on. LTE radio and GPS also always on. Before I'd have wifi turned off on sleep, GPS off and occasionally LTE and mobile data to extend battery life.

How to disable Google Services Framework without disabling your phone

I'm reading through this thread in search for more info on the cross-device Android OS/Android System battery hogging disease. While I have not found anything new yet I might have some news for you. It is definitely possible to freeze gsf and its ilk, I've been doing this for about as long as I've used Android.

To freeze Google I use the following incantation:

#!/system/bin/sh
# disable-google-services
pm disable com.android.vending
pm disable com.google.android.gsf
pm disable com.google.android.gsf.login
pm disable com.google.android.location

To revive Google for those rare cases I feel the need I use this script:

#!/system/bin/sh
# enable-google-services
pm enable com.google.android.location
pm enable com.google.android.gsf
pm enable com.google.android.gsf.login
pm enable com.android.vending

I use these scripts on a Motorola Defy+ (mb526) running a slimmed-down version of cm10 with a very slimmed-down version of Google apps (only vending and related bits, really). The phone runs fine without gsf. I might go so far as saying it runs better. The only slightly annoying aspect of this way of corralling Google is you'll be asked for your Google account every time you enable gsf - It'll remember those details until you use the disable script. I don't see this as a big minus but if you dislike typing or have difficulty remembering passwords you might.

If your phone runs essential code which hooks into gsf this might not work. You could replace that code with something clean, or learn to love Google. Not having a Samsung I can not vouch for the applicability of these tricks to those phones but for me there is a clear distinction between Android and Google. The one can exist without needing continuous access to the other.
[Android General] axpira:
Great but when I run

pm enable com.google.android.location

i need to restart my phone to use Network Location again.

Do you have the same problem?

In my case the dialog "Location Consent: Allow Google's location service to collect anonymous......" only appears when i restart phone.

Thanks

smdcntl0 kernal wakelock

I have seen that this has come up a few pages ago and I did not see a response to the orig poster. I too am having this issue and not sure what the culprit is? I have searched to my hearts content and have not found what the cause is.

Any help?
[Android General] razen_kain:
Awesome thread. I read and re-read the op. Then read it again and took down some notes.

I was wondering if you knew anything about the kwl L2_hsic. It's been giving me fits and I can't seem to find find any definitive info on it. Most of the time it its very small but every once in a while it will get very high. Thanks

[Android General] T.J. Bender:
Quick Google search suggests that L2_hsic is caused by fast dormancy.
[Android General] razen_kain:
Yes. I read that in my more than quick Google search. It ALSO says that it is related tip hi speed interconnectivity chip and also says that no one really knows what it is.

While searching Google and XDA the only solution I could find to it was to pull the battery, replace it and reboot. Which solved the problem, as one might expect, only temporarily. The offender still comes and goes at will.... I am beginning to think that the latter answer is the correct one.

And again, thank you for this. It was quite informative :)

[Android General] T.J. Bender:
How long has it been since you did a full-wipe install of a ROM? Anytime I've had an issue like that where pulling the battery and/or rebooting gave me a temporary fix, it was a rogue process and a full-wipe reinstall of my ROM did the trick. Not necessarily endorsing you do that here if you've found a solution you can live with, but make a note of it next time you wipe and see if it comes back.
[Android General] razen_kain:
I just recently did a full wipe, about three days ago, and the wkl has gone back to staying below 1% since.

From experimenting with bbs I think you are correct about it having to do with fast dormancy.

Last night my phone got 97.8% deep sleep even with the wkl being at the top of the list it was less than one percent

EDIT: checked my notes. It was actually 98.7%. It is the highest I've ever gotten. :)

[Android General] T.J. Bender:
97.8 deep sleep is about as good as it gets. My Skyrocket was typically around 94-97% when I was using it as a phone and leaving it idle, and I couldn't even tell you what my Note II's idle DS % is, because I hardly ever stop using the thing.
[Android General] bso44:
Anyone know what "Event Log Service" is and how to stop it? For a past few days, it's been the number 1 cause of my partial wakelocks in BBS. Just as an example, in a little over 7 hours since boot, "Event Log Service" has kept my phone awake for an hour and 22 minutes.

Ccci_MODEM Wakelock

Hello folks. I'm currently trying to track down what eats up battery so much in standby on my Wiko Cink Slim (MT6577-based Tinno rebranded phone). I've read the excellent writeups (thanks!), I've

bought

(yes I did) BBS, and now I've nailed it to a kernel wakelock called CCCI_MODEM

This guy is on over 20% of the time and obviously prevents the phone from staying in deep sleep (it is only 60-70% of the standby time)

No useful Google hit on this one, searching for this string in the kernel sources published by Wiko has failed to find anything.

Not much useful coming out of BBS stats apart from this: no offender app, not much in partial wakelocks.

I'm stuck. Anyone would be willing to define "CCCI" for me for starters? or point me to the right direction? many thanks in advance for any (even tiny) bit of help you can provide because I have no string to pull at this time.
[Android General] sh0cka33:
Have you tried other modems? That seems to sometimes fix modem- related wakelocks...
[Android General] Lannig:
Huh? what do you mean by "other modem"? It's my understanding that the term "modem" actually refers to the built-in 3G hardware, not an external modem (no such thing anyway).

Or I am missing something here?

Based on my findings the only reference to this "CCCI_MODEM" string found in the /system filesystem is in a kernel module called ccci.ko which seems to be among the closed-source bits of the Mediatek kernel :(
[Android General] xcrazydx:
Modem= radio(software flashable)
[Android General] Lannig:
Thanks for your reply.

You mean the firmware image that is -I presume- loaded into the 3G chip at startup time? (or only once? I don't know)

Yes, there seems to be such an image in /system/etc/firmware/modem.bin if that's what you mean, but I don't have the slightest idea of

- where to find another one (I have the most recent phone firmware update from vendor), I guess that it's very model-dependant and maybe even country-dependant isn't it?

- how to flash it into the 3G chip if that's necessary

Other people using the same phone don't seem to suffer from the same issue, although we are at the same phone firmware revision level.

I'd say that it doesn't seem to be caused by an application, obviously there are other possible causes (such as which operator, which location) that I haven't ruled out yet. I was just trying to make sense out of this CCCI_MODEM name and get clues at this point.
[Android General] xcrazydx:
What phone and Rom are you on? If you have a skyrocket, we have a section for flashable radios.
[Android General] mtdew:
Our actual modem firmware is not located in /system but exists in its own partition untouched by the ROM or anything else we flash.

What's in /system is likely used to communicate with the modem.
[Android General] Lannig:
Ouch. Sorry folks, I've just realised that this thread (that Google had found for me) is not a generic discussion on wakelocks, but is part of a model-specific section of XDA. I had missed this. So I'm kind of off-topic here, having a completely different phone from the Galaxy S II Skyrocket (an obscure chinese no-name rebranded by a french importer). Anyway thanks for the tips, it's quite possible indeed that my problem is linked to the modem firmware. I won't find more clues here, since it's likely to be specific to brand+model. Sorry for the noise again.

Hello guys,

Im having AudioOut_2 wakelock and I have been trying to remove it with no success.

I have untick all system sound exept auto haptic.

Music player is n7 and I have untick all headset options.

How can I get rid of the leecher?
[Android General] odub303:
That wakelock is held any time the device is supposed to be playing sounds, regardless of whether the screen is on or off. I doubt it's causing you undue battery drain.

[Android General] deom2i:
This wakelock prevent my phone to go to deep sleep. Thats the problem. Its 100% active and no deep sleep at all.
[Android General] Neverender326:
So it's active while you're not playing media? Try rescan media root from the playstore...disables media scanner.
[Android General] mtdew:
If you read the op it tells you that wakelock and how to kill it if memory serves.
[Android General] sh0cka33:
Any apps that produce a sound will cause that wakelock in order to produce the sound. Minimizing it would require you to monitor the wakelock while removing certain programs.
[Android General] T.J. Bender:
This. You have a rogue app, and the only way to find it is to try them one by one and see which app causes a wakelock that sticks a couple of minutes after it's off. Target media apps first, then games.
[Android General] andd64:
+1, any idea if something like this exists?
[Android General] deom2i:
Mate, how to deal with this? By uninstalling all apps or is there any software that can track this?

Give this app a try. Takes a few days to gather data and figure out what's draining your battery though.

Couldn't media scanner fall under media wakelock.

Pretty sure the Media Scanner only shows up as MediaScannerService (or something like that). Don't think I've ever seen it as the name described or just "Media".

IF you uninstall Google Maps, how big of an affect does it have on getting the best out of Google Now? I probably won't uninstall it anyways, as there's a point at which you end up not having a smartphone anymore, but I'm just curious. Thanks.
[Android General] bobdoblo:
A little tip is to unistall it and redownload it from Playstore so then it is a user app not a system app.

It supposedly has less wakelocks and you can now Greenify it. http://xdaforums.com/showthread.php?p=38192418

Also set it up in Gemini to stop autostarts on it.

[Android General] Eason85:
I thought I was experiencing high battery drain last night, so I left my phone (Xperia V 4.1.2) off the charger and compared it to the drain of my Xperia P (4.0.4 stock). My V lost 17% in 8 hours, the Xperia P lost 6%. The weird thing is, I checked CPUSpy- it reported that the phone was in deep sleep for about 7.5 hours out of those 8- yet the battery graph showed a lot of wakes during that time. Also strange is despite the deep sleep %, BBS reported that there were about 2 hours of wakelocks- both alarmmanagers. The top was android system, the other was media. I checked a dumpsys alarm and found nothing out of the ordinary, however. WTF?
[Android General] razen_kain:
I've been having the same problem with bbs giving me stupid wrong %'s. The only fix I've found is, when you unplug it set a custom reference point then.

I know that this forum for S2, but I have big problem,and plese you to help me,or explain me what I do. I must say that thic ROM, is notgood, he get very much errors,and I think that it maybe cause for drain battery.When go in wake lock detector I see, that some app running,but I this app off before some time,and screen goes in off,and this app work.Maybe ROM dont work good, and dont put app in off when phone go in deep sleep.I think this,I dont know nothing about battery,and what is cause for drain.

Hello, I have Alcatel ot 990 and AOKP Milestone #6. Somthing drain my battery very fast.Example when battery full - 100% for 4hours battery spend about 50-55% in deep sleep, I dont touch phone. In Battery better stats app, when look somthing which name is this AWAKE - alwys over 30%, NO DATA CONECTION 100%, NOOR UNKNOWN SIGNAL-100%, SCREEN ON alwyas show like work full time, I must say that this options shows when phone in deep sleep. I confused with this no or unknown signal and no data conection, why always show 100% when phone in deep sleep. And this-awake.When look in applications/running, only work app which I rigged to work, and some app of system.

Here screen shot for this options .

[Android General] aca89:
@dejanxxxx, you have tons of deleted wakelocks. You were obviously trying to delete unnecessary applications without clearing cache and data of those apps. See second post and what it says about deleted wakelocks.

And this is layman's opinion someone please correct me if I'm wrong.
[Android General] dejanxxxx:
I see, and I clear from CWM-Wipe dalvik cache, and use app Sd Maid and clear rest of app which I deleted.
[Android General] aca89:
Your deleted_wake_locks time is still very very high. It shouldn't even exist and in your case it's there almost always. If it doesn't represent a problem, I highly recommend you a clean install of rom.

If you decide to do make clean install;

backup your apps with titanium 'cause I can see that you're using it, wipe everything (data, cache, dalvik), flash your zips (it doesn't matter if it's the same rom as in zip file, flash it anyways). And this time if you want to remove undesirable apps,

first go to manage apps, force stop them, clean cache and data where available and then delete them using titanium or manually

. Afterwards, restore apps you backed up earlier.

Greenify is a bandaid for lazy people who refuse to put in legwork to find the real problem. Seriously it's like putting a bandaid over an area that needs stitches.
[Android General] NoSpamDan:
Ever tried Greenify?

The beauty and power of Greenify is for apps that don't have the ability to disable push notifications, or things like Google Maps that you don't want running all of the time in the background, but still want to use them occasionally.

You could use Autostarts, or ROM Toolbox's Startups utility, or freeze apps manually that you don't use, but when those apps are opened they can start chewing through your battery unless you tediously re-freeze them. Greenify gets around this, and quite nicely, I have to say.

Whatever gets better battery life without turning my smartphone into a dumbphone is fine by me. Never was particularly fond of stitches anyway, LOL
[Android General] whatlobster:
Except it obviously works for that poster. I don't understand why you have to keep repeating that bandaid thing. Not everyone wants to disable all notifications/data activity. It's about finding that happy medium, which differs for each person. There's no need to call people lazy.
