Can someone tell me what this wakelock is/means? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

My battery has been excellent with this phone since I rooted it and froze a ton of unwanted apps. Especially when the phone was idle "sleeping."
I woke up this morning about 40 minutes ago and unplugged my phone. I was on the phone for about 10 minutes checking emails and such. I came back to the phone just now and noticed I had drained an unusual amount of battery over a very short proud.
I screenshot a few BetterBatteryStats pics and some pics of my battery drain and screen time. Thing I am concerned about is the phone being awake for so long and that "deleted_wake_locks" kernel wakelock. Can someone tell me what it is and why its destroying my battery out of no where?!

This is what deleted wake locks means from BBS: https://github.com/asksven/BetterBatteryStats-Knowledge-Base/wiki/deleted_wake_locks
Basically its a lumped up category for wakelocks that have been deleted from your system such as lets say you were using some App, that caused wake locks as normal, then you deleted that app, those wakelocks are still logged but now are unknown since the app is deleted, so it puts them in this category.
Technically a reboot would eliminate this wake lock, but if you still seeing it, wipe the cache and dalvik.

Walk me through what you do to attain zero wakelocks please.

Juice defender, no juice defender, ATK, no ATK.
I get great battery, but betterbatterystats is still reporting wakelocks from google services and facebook.katana. Sync is on ONLY for facebook with 3 hour interval.
I used titanium backup to freeze:
-email
-gmail
-maps
-kies
-talk
You will never have zero wakelocks, as they are how the OS works.
If you have apps keeping a wakelock longer than they should, or when the screen is off you have a problem.
Also check the graph in settings > about phone > battery, if the awake and screen on lines line up apart from where you may have been downloading stuff, talking on the phone, listening to music, anything else where it would make sense for the phone to stay awake when the screen is off, then you are ok.

oh the phone sleeps perfectly, I just thought there was room for improvement what with 2 minor wakelocks. just a junkie for tweaking .
I un froze everything gonna scope out the batt life with no power saving apps/features.
[edit]Success! I got around to freezing some more .apk's with Titanium as per https://spreadsheets.google.com/spreadsheet/pub?hl=en_US&hl=en_US&key=0Ag43oj7rLQP4dENZcmhGN0ZUa3pHSENVeXlqUm5vV0E&single=true&gid=0&output=html
and I'm getting 1mA power draw in idle/sleep according to BetterBatteryStats. Before I froze a few extra apps my best was 20 mA in idle.

you want zero wakelocks? buy a nokia 3410. As mentioned its excessive wakelocks you should worry about. Zero wakelocks means no point having these type of phones as you wont be using any of its features.
A logical step would be to actually use the phone for a week or two and monitor the wake locks in conjunction with what you are using on the phone .

The easiest way to do this - completely serious - is to just shut the phone off when you're not using it.
When you want to use the phone, you need to wait for it to boot up. That's one button and 30 seconds or so.
To freeze and unfreeze apps as you need them will take just as long, be MUCH more tedious, and still drain more battery while the phone is in sleep mode.
booting the phone drains a fair chunk of battery though (at least on my previous 2 phones)

Battery problems?

My new note's battery seem weird after I let it run to 1% and then charge up to 100%.
After that, it seems to lose battery very much faster.
Left overnight, it went from 79% to 49%!! a 30% drop!!
I checked Battery status report battery health is good and average 33-35 degrees temperature.
Bulk of battery usage is reported for Display (62%, "time on" of 1hr 30m) ...
Is this normal??
What can I do?
Thanks.
Maybe the battery needs some recalibration, run it down to 1% then charge the phone while its still off.
Here's the battery level profile...
Not sure what is keeping the phone awake even while screen-off??
Any help or advice to diagnose and resolve the battery issues appreciated.

Try a factory reset and then calibrate the battery.
Just woke up after the first night with the Note. I had 45% battery left when i went to bed, and now 9 hours later it's at 43%.

You diagnosed the problem correctly by identifying the device being awake while the screen is off. I suggest two tools to narrow it down:
1. Cpu Spy, Market, free, displays how much time the CPU spent in the different power states. During the night it should almost completely be in deep sleep.
2. BetterBatteryStats, Market, ~2.50$, allows to identify apps with wakelocks, apps which prevent the system to enter the deep sleep power state while the screen is off and the device basically is idleing. On CM Spareparts xan do that for free, for Samsung devices I first have to find a free alternative app that works...
No wipe needed (yet), no delete this or do that. First find the villain, then shoot em, not the other way round.

Installed BetterBatteryStats,
but there is lots of information, and I have little clue what these constitute or how to identify what apps cause the issues??
You could post screenshots of all the screens of betterbatterystats and we will try to help you.
Charge the phone to 100% and disconnect it right before you go to sleep, enter cpuspy and reset its counters. Then enter task manager and kill all the programs and clean the memory. Now go to sleep and when you wake up post screenshots of the built in battery stats, betterbatterystats and cpuspy.
Hi
I have a similar problem, my battery keeps draining entirely too much for what I think it should. Mine gets drained about 40% in about 10 hours of very light use.
BetterBatteryStats shows it is WiFi that has a humongous amount of wakelocks, but the thing here is I have WiFi disabled.
Image (BetterBatteryStats): http://antti.vahtera.org/images/SC20111221-020623.png
CPU Spy shows nothing that looks that weird to me, although I rather wonder why so little deep sleep and so much 200MHz, but that might be if deep sleep has a longer "counter" than it did on SGS/SGS2. If I use the phone to check time, or twitter from a widget couple of times per hour, does SGN enter deep sleep during those "breaks"?
Image (CPU Spy): http://antti.vahtera.org/images/SC20111221-020441.png
But, the one that caught my eye, was the stock Battery Info window. During the (almost) entire 10h time the phone was awake?! Why in the whole wide world? Does SGN really have some bug with WiFi keeping it awake even though it is disabled?
Image (Battery Info -window): http://antti.vahtera.org/images/SC20111221-020744.png
I really wanna get behind this. I love this phone, but this battery drainage begins to be a problem for me. I got about 2-5% drain per night with SGS2 and 10-15% per day on similar usage.

yeah, there's something seriously wrong with your phone. Are you rooted ? would you consider a full wipe and maybe a different ROM ?
Not rooted, not modified in any serious way either. (Using GO Launcher EX, not TouchWiz launcher, that's really the extend of modification on this phone.)
Android version is 2.3.6, Baseband N7000XXKK5, kernel 2.6.35.7-N7000XBKK4
This is what was shipped with the phone. It's unbranded and unlocked.
I haven't really done anything to it but installed apps from Android Market (and a couple with Samsung Apps).
EDIT: This is my day-to-day phone with all settings as I like them and all things set, so I would like if I wouldn't have to do a full wipe. But if nothing else helps, I guess I'll have to, in the end.
I hope someone will be able to help you cause I've never seen anything like that.

This might help...
I had the same problem. The first night my Note was dropping from 100% down to about 50% when I was asleep and the screen was off.
In the battery stats I could see that it was the Android core that used all this power.
So I tried a couple things to see if it helped:
1) I went to WiFi-settings and set it to turn off WiFi when screen off. This is a setting that is not on by default, you have to set it yourself.
2) I turned off AutoSync (Google account and so on)
Those to settings removed the overnight powerdrain problem. The next night it only went from 100% to about 98% when I slept
And since I am a serious betterysaver I also turned off autolight on screen, and set it to lowest light possible (still nice picture). I turned on the "Autoadjust screenpower), turned off all animations, turned off all kind of vibrations on the phone.
I left the"System powersetting" alone. It didnt save much power and it made the phone slower.
All in all, now my battery is great, I still have lot of juice left after a full day of using my Galaxy Note
I seem to have fixed my problem, without having to do a full wipe. I don't know which part it was that finally did it, but I'm glad it now behaves like I think it should. (about 2% battery drain in ~5h in pocket, one 1min phonecall and two or three times checking time from lockscreen.)
Anyway, I apparently ALSO had the infamous problem with Mediaserver eating humongous amounts of battery, so I'm not sure if that had anything to do with the WiFi keeping it awake or was just a separate problem.
Long story short, here's what I did:
a) installed JuiceDefender, had it manage Wifi
b) turned Wifi on, restart
c) turned Wifi off, restart
[d) installed nomedia manager and excluded most directories from mediascanner]
e) turned phone off, recharged to 100%.
Seems to be working now. No WiFi wakelocks, no mediaserver eating CPU, deep sleep ~70% of the time.

Finally fixed my battery drain!! Turned out to be Yahoo Mail!!

I have been reading a lot at this and other forums trying to find out why my phone would drain 5-7% per hour with screen off even though after installing various combinations of custom roms and kernels and following suggestions made by other users such as monitoring partial wakelocks in BBS, freezing applications, undervolting, turning off sync etc.
Having spent many frustrating days on this I finally managed to locate the root of the problem and wanted to share this with other i9100 users and hopefully this helps someone out there.
What I noticed was that after installing a customised rom (i used checkrom, hyperdroid, villainrom) the battery drain would be <1% per hour and the screen on time closely matches the awake time. However, once I had restored all my apps using titanium backup, the battery drain would go back to 5-7% per hour. I checked BBS but there was no particular app showing which was causing partial wakelocks (except the usual alarmmanager, etc) so I always thought it was a rom/kernel problem and not an app problem BUT i was wrong, it was an app that was causing my battery drain (in my case it was the yahoo mail app) and for some reason it was not showing up in BBS as causing wakelocks but u knew it was chewing up my battery as the awake time kept on increasing while the screen on time was not. Now I am using k9 install of yahoo mail and battery life is great!
I found this out by simply doing the following:
(a) Install a custom rom and kernel (I used checkrom HD v4 and siyah 2.6.6)
(b) Turn off sync, notify new apps, google ad
(b) Install cpu spy and BBS
(c) Open cpu spy and reset times and then quickly exit the application and then press the power button.
(d) About 10 minutes later, turn on the phone and quickly check cpu spy. It should say that the phone was in deep sleep at least 9x%. Also check BBS, the wake on and screen on time should be very similar.
(e) Then install titianium backup and start restoring 5 applications (I chose 5 but you can choose more or less)
(f) Go back into cpu spy, reset times and then press the power button
(g) Repeat steps (d) to (f) until you find that the deep sleep % falls below the 9x% and then delete each of the recently restored apps and repeat the process till you get back to 9x% deep sleep.
(h) Hopefully you would have found the rogue app then its time to find an alternative app!
Hopefully this helps!
Weird yahoo mail doesn't seem to drain that much of my battery, but I'm not really sure as I change roms so often I have no idea what normal drain for LA2 is(probably 2mA). I did noticed that it almost never used 2mA with data on.

A suggestion for you since you don't seem to be aware of it.
You didn't have to look at it for days and days looking only at partial wakelocks pull down tab.
All you had to do, was to go to bed on a full charge, then read the text file that you can dump from that app.
It contains partial, kernel, alarm wakelocks and processes.

2mA is bogue, in fact, all mA reading is bogus.. it's an estimated value by an app calculated every 5 mins or whatever you have set at, unnecessary wakelocks justs so you can get some fairy/harry potter numbers.
Only way this could be true is if you wire a multimeter to it.
It may be bogus, but it still shows drain somehow. What other could I ever place on my 3rd screen without the big battery usage history?

I agree that yahoo apps are bad. At least when I bought the phone with stock 2.3.3 and installing yahoo mess & yahoo mail my battery drained very fast and I didn't know the cause. The phone stayed awake most of the time even if the screen was off.
I had a hunch that maybe one of the 2 yahoo apps caused this and uninstalled everything yahoo related. Since then, my battery life was great.
Yep....and most of the time there are better alternative apps....just need to look for them. The battery still drains fast when i am using it but at least when i am not using it (which from my usage history is about 60% of the time on a normal day) its taking just taking 1% per hour and allows me to survive till i am back home to charge for the next day!
I never use yahoo mail in my sgs2 but my battery drain as normal, so i think no reason to talk yahoo mail is the reason.
He is right. I had problems with yahoo mail too.
One thing I noticed is that even though it has sync it does not show up in bbs. I mean it has sync so it must be using some battery over time, but it does not show up at all in partial wake locks. It show that the system is not reading the drain by yahoo mail. Such kind of battery usage shows up as android os.

Just use gmail instead =]
Yahoo messenger is really bad, it does cause a lot of drain, it runs about 13 processes, whilst skype hardly runs 2 or 3. Disabled start up for yahoo messenger using startup manager and running processes by AutoRun Manager. Unless necessary I don't use yahoo messenger, skype only
Never used yahoo mail in my phone.
Yahoo mail and Facebook apps were draining my battery,just stop auto sync and it's fine. )

Excessive Deep Sleep Battery Drain

Some of you may have noticed that battery life on this phone can be both unbelievable and mediocre. I've been trying to figure out what can trigger and cause mediocre performance and I'm at a loss. The problem is, there doesn't appear to be a smoking gun. No obvious wake locks. No rogue Apps. I have Carrier IQ disabled by System Tuner. Google Now is off. What I'm running right now is pretty bare bones. And the kicker is my phone is sleeping, as can be seen in the shots below. The vast majority of the time my phone was off the charger it was in deep sleep mode.
I noticed my phone in excessive drain mode Saturday so I let it run over night and into the next day, so that BBS and GSam could pick up as much data as possible, including sitting idle overnight and very little use throughout yesterday.
Here are some shots to show the story. The graph, which is definitely steeper than when idle drain is normal, which resulted in idle drain of about 6% per hour. Also as can be seen in these shots, there is not a wakelock problem. Deep sleep shows as 12 hours 38 minutes, Awake time of 1 hour 8 minutes, and screen on time of 1 hour. So, my phone was only "awake" for 8 minutes when the screen was off out of almost 14 hours according to BBS.
I did notice and oddity here though. BBS listed the unplugged status as 13 hours 47 minutes, while the phone's battery meter listed it at 12 hours 13 minutes.
Attached are the shots I took at 19%, as well as a final battery meter shot after charging the phone to full while powered off and restarting, where it's been purring like a kitten in deep sleep.
Part of me is beginning to believe there is a bug with the battery gauge. What do you guys think is going on?
Try clearing data for google play services,google services framework and playsore than reboot and check if things changed.
And i would recommend uninstall the updates related to those apps and let them update itself again.

Done. Although I won't know if any attempts to resolve the issue have worked until the idle drain triggers again (or doesn't).
Thanks for the advice.
Well unfortunately that didn't solve the issue. The heavy deep sleep drain again triggered after a bit over one full day. I charged to full last night and let sit over night where it drained 6% per hour with no obvious culprit. Anyone else have any suggestions?
It seem that your signal is week, did you get stable signal and have you tried airplane mode, to find out how much battery drain in this mode?
Also, did you disable LG MLT? This is a massive app from LG, can consumed about 150 MB RAM.
This might sound boneheaded, but what about just resetting the phone. Maybe some system app is causing some type of memory leak and thus draining your battery. Also disable wifi when you're not using it.
I don't think it's signal related. I get an excellent signal at work and the idle drain still occurs. Also, it happens whether wifi is on or not. I have not disabled MLT, as I'm not concerned about RAM, just running processes. Rebooting the phone eliminates the issue, so something is obviously getting hung. The really odd thing is I was draining 6%/hr overnight, all while the phone was in deep sleep, yet my top battery consuming category was the screen at 35%, with just 1 hour of screen on time of 10 hours off the charger. If something was cranking in Android System that caused 40% drain overnight I would have expected Android System to be higher. It doesn't make any sense.
I may just have to factory reset.
My battery's been great until couple of days ago when I turned on GPS and Voice Notification (for speaking out names when phone call/message comes in). After I noticed the abnormal battery drain, I turned off those two options, because that's the only thing I did differently before noticing the drain. However, that didn't help... yet. I needed to do a reboot and battery's been fine again. Not sure if those two were the actual culprit, or just coincidence.
Have you changed any settings right before you noticed the drain? Just a thought.
had the same issue., wakelock detector, BBS, GSAM nothing could show what was eating the battery. i use mobile browsing a lot and almost 8/10 times this battery drain was happening with chrome , chrome beta and firefox browsers.
Only thing thats helping me is the Greenify app . Greenified the chrome and firefox and almost all the cloud apps and the battery is now much much better.
still ...IT IS AN PROBLEM to be found..
To provide a bit more info on this, attached is a pic of my reboot a couple hours ago (marked by the thin white vertical line). The change in the slope of the drainage line is drastic. Also, notice the small hump after the reboot? The line actually increased a bit, fell, then flat lined. More and more I'm beginning to suspect the battery gauge, but I just don't know.

I have the same situation after charging. Even in"deep sleep" it would chew through the battery. Now I just reboot the phone after charging and it plays nice. The gerbil on the wheel seems to take a break and rest.
To all who have excessive battery drain, did you charge your phone while it is on or off?
Some where in this forum (if not mistaken), I read that there is a bug while charging G2 when it is on. You should reboot your phone after it is fully charged otherwise you will experience excessive battery drain.
Mine always charged it while it is off and never had problem with battery life.
i got the same issue which is very annoying, have over 85% deep sleep, no wake lock, battery draining like crazy, and it happens randomly. I wonder if factory rest fixes the problem, or hardware issue
i have done a bit testing for this random drain,
with mobile signal on ==> huge drain
without mobile signal on and only phone signal ==> huge drain
airplane mode ==> no drain
so i believe it is a bug within the phone software, actually sometimes the random drain started after a phone call
I've been getting the drain too in the past few days. Last time i could fix it by factory resetting, but obviously I don't feel like doing that once per month. What I do know is that flashing another stock ROM (kdz) without factory resetting doesn't fix it. However last night I figured i'd try disabling WiFi (kept it on during the night until now) and I only drained 1% in 5 hours, down from 3% per hour. Perhaps this bug is related to WiFi.
Have you disabled LG MLT? It acts like CIQ for internal LG purposes. I have personally seen it cause mass wakelock in unexplained situations. If I leave everything on overnight under 95% battery, I will get around a 3% drain in about 7 hours. Pretty normal. The first 5% on these batteries seem magical. At 100%, with everything on, I wake to 100%.
Yup, frozen in TiBu. Will be factory resetting however when I get home as GSAM grabbed my attention. Never were system things so high up the list when i had no drain.

I been struggling with this since I got the phone (almost a month now). I've done all the usual:
Removing bloat
Disabled CIQ
Disabled Google Now, Location, GPS
and I have the same apps as my Nexus 5
Just last night I realized that this battery drain only happens after taking it off the charger. This got me to add the word "charging" in my search and I found this thread.
Is this hardware related, or would a custom ROM resolve this? I have the AT&T version.
Ok and which stock rom does not do that?

Guys could you write which stock rom does this wakelocks for you so we could eliminate corrupt firmwares?
For example I experience these wakelocks on latest F international version.

Massive battery drain

Hey guys. Recently my battery has been dying at an alarming rate. According to BBS it's from a process called diagnostics.client.Wakelock, does anyone have an idea what could be causing this?
I started noticing the drain after setting up my Galaxy Gear, don't know if that may have something to do with it.
Thanks!

Thanks! I'll give that a shot.
I am facing a huge battery drain as well after the recent update was pushed. I don't have the "diagnostics.client.Wakelock" in BBS but Samsung Push Service was hogging a lot so I turned that off. It was 80% at 11PM and today morning it was down to 59% .. that's 21% in standby mode. Is it not going into sleep mode or is something else causing this? I have almost everything turned off. Any ideas guys? Thank you.
MJ7? (not sure why but like other people remarked - the battery life looks to have somewhat declined - 30-60% less?)

Yes MJ7. I hope this is a bug that can get fixed sooner than later. It's horrible. I just got 1h 37mins of screen time and now I am down to 12%. Just a few calls and some Instagram. Nothing else. Would removing the battery for a while or something help? I haven't installed any app since updating to MJ7 (2 days ago).
I've had this issue with MI7 and MJ7 so the update is not the problem. My guess is me freezing most of the samsung bloat on the phone through Titanium is causing this. Maybe there's a process trying to find something thay I froze?

I fixed it by charging my battery up to 90% then removed the battery and kept it aside for a while ~10 mins and then plugged it back in and charged it to 100%. Now it seems to be normal again. No drain last night. Moved only 1% from 12AM to 9PM. Cheers!
I have the same issue with MJ7 firmware; the phone sometimes doesn't get into deep sleep while the screen is off.
A possible cause of the issue: switch off wifi when data are off.
So now I switch data on before turning wifi off.
Anyone ever find a solution to this? It's killing me.
Same here, my battery declines almos 1% every 5 minutes just texting via Whatsapp and I know Whatsapp is not the guilty. Using Wakelock monitor shows 30% Android System usage with a lot of entries in Gpslocationprovider (even with GPS off and everything on Location settings off), SyncloopWakelock and AlarmManager... MJ7 here too... My Note2 wasn't like this... I finished the day with 5% of baterry after heavy use from 8am til 10pm (including 45' watching videos)... With my Note3 at mid-day I have my battery death!! I can't believe it! and I don't know what is happening (I only have 4 days with my new Note 3) and I have tried almost everything (deactivating) except wipe data/factory reset (I've tried soft reset and nothing)
Anyone ever find a solution to this wakelock?
anyone find a solution?
Delete Google search from system apps and deleted Google play services. Redownload both from play store. Seems to help.

I noted that my GN3 would have great and then poor battery drainage. It seemed to happen right after my first long call of the day. I noted in my wakelock app that diagnostics.client.wakelock was using a lot of time.
I decided to take more drastic action by doing a factory reset and restoring apps one by one. I first used Kingo Root to root my GN3. I had to uninstall Kies and the Samsung driver to get the rooting to work.
Then I backed up with Helium and Titanium backup.
After a factory reset, my battery usage was about 0.2 percent per hour. I use only data and no wifi.
I have now restored most of my apps and still have 0.3 percent per hour usage. I have not updated any Samsung or ATT apps.except for ATT code scanner. i have not "used" any of the google apps except for gmail, search, google+ (signed out). Google music is turned off.
Diagnostics.client.wakelock still shows up but with low time now.
After twelve hours, the GN3 is at 96 percent including a two minute phone call and email updates.
------
After a long phone call, I once again saw my battery usage increase and stay up after the phone call.
-----
I re-started with a factory reset and only restored the minimum apps that I use to browse, email, text, phone, and backup.
So far it is performing well in battery usage.
I will be adding more apps until I find the one that breaks the good performance.
-----
So far I have been able to make it through 24 hours using only TEN percent battery usage. I have added TextPlus, BofA, drippler, Helium, Titanium Backup Pro, CPU Spy Plus, Wakelock Detector, System Tuner Pro, Battery Monitor Pro, AutoBluetooth, Maps, Youtube, YP, Total Commander, Visual Voicemail, Quick Boot, Root Checker, Turn Off Screen. Everything else is stock without updating AT&T apps or Samsung apps.
I am seeing an idle usage of less than 0.3% and that is with two widgets for Battery Monitor and System Tuner. They and Textplus use up the most power. I also talked on the phone via bluetooth for about 30 minutes.
I still get the diagnostic.client.wakelog but only getting about 5 percent awake time.
-----
I did another factory reset. This time I did not allow any app updates.
I installed Titanium Backup, CPU Spy Plus, Wakelock Detector, Battery Monitor Widget Pro.
I have not seen a diagnostic.client.wakelock at all after one hour of use.
-----
I added TextPlus, System Tuner Pro. I put the widgets to System Tuner pro and Battery Monitor on the home screen.
I have not updated any apps since the reset.
I have counted about 7 diagnostic.client.wakelocks for a total of 4 seconds of wake time. My wake time percentage since yeaterday is around 1 percent.
I plan to update apps one at a time to see which one kills the battery usage with wake locks.
I just added AT&T Visual Voicemail, PayPal, BofA, and Evernote to my GN3.
The diagnostics.client.wakelock started climbing and keeping my phone from sleeping.
Uninstalling the four apps did not help.
I think that the problem is with the Visual Voicemail.
----
Factory reset my phone and am back to 1 percent wake state and very low battery drain.
----
The cause of the bad wakelock was due to restoring APP+DATA in Titanium Backup. I did that to save setup steps.
I had restored BofA and Shazam with data and the wakelocks started up.
After I factory reset again, I installed apps the normal way and have been seeing a 0.3 percent use per hour.
Samsung's own software is most garbage in my opinion.
If you use ChatOn and Samsung Hub, etc, disabling this may have an impact.
Here's how I've solved the problem with this pig of an app.
1) go to application manager under settings.
2) go to the "ALL" tab
3) find that "samsung push service"
4) uninstall - this will only uninstall the updates. Once all the very useful updates are gone, the option changes to disable.
5) disable and good riddance.
On a side note, search for this on the playstore. the reviews are hilarious.

Nothing I had tried up to today has fixed my battery drain and diagnostics.client.wakelock issue.
However, today, I got a software update OTA (nb4) on my phone and it appears the problem is fixed.
