[Q] PowerManagerService wakelock

I am monitoring my battery through BetterBatteryStatus. I see that the PowerManagerService kernel wakelock is keeping my phone from going to sleep. It keeps the phone on for nearly 120 mins in a day. Any idea of what that could be? I suspect that it is due to the Smart Stay feature of Galaxy S3 and I just disabled it now.

I'm getting this on CM 10.1, so no power stay. Wondering what it is too though.

PowerManagerService is basically a catch-all for partial wakelocks (wakelocks requested by non system apps). To see which apps are actually requesting the wakelocks, go to the Partial Wakelocks screen.

Is there any way to drill down this service and detect what exactly is draining the battery?

Use Better Battery Stats. instead of looking at the Kernel Wakelocks, switch it to partial wakelocks, and if I understand correctly, the sum of the partial wakelocks is effectively the powermanagementservice wakelock

Just wanted to say that i too had a lot of partial wakelocks draining battery on my SGS3 CM11 (using ART) but I've managed to solve the problem via cleaning the cache in settings->storage. Since then, the CPU is awaken only 19% of time and my batt last 5/6 days with WiFi, Now etc.. (I have a 7000mh zerolemon)

Have you seen any benefits by switching to ART?
If I clean the cache, what will it delete? Will I lose all my App settings and game levels? I have about 54Mb in there.

I just tried clearing and a message came up saying "Security policy restricts clearing of this app's cache."
Is this normal? How can I find out which app is causing the problem?

I have a Samsung galaxy note 2 and every time I lock lock my phone it suddenly turns right back on. It's been happening for two days now. I've tried factory reset and hard reset.. nothing seems to work. Looked at several forums but none seem to help either. Use wake lock app and it says this ..see attachment

Same here with various audio partial wakelocks that add up to 12 days of kernel wakelocks. This started when I upgraded to:
gapps-kk-20140606 & cm-11-20140611-snapshot-m7-snapshot kernel 3.0101-cyanogenmod-g329d6a1 build03 #1
I have gmail sync disabled but contacts sync on. I notice CM have added apollo to the lockscreen so this could be a bug I need to search for

@kmry Gave you resolved your battery drain issue?
I'm on HTC 10 and have the same issue with huge amounts of wake locks. The device basically never goes into deep sleep.

Google Maps-GPS consuming battery time even when turned off

If I turn on the GPS, do some navigation or maps and then I turn it off the GPS, google maps keeps draining battery, like in this picture (not mine)

As you mention here on basis of that Sir,i would like to tell you that try making app forced closed and check,because sometimes app like Google Maps or may be Google+ they try to run on background in order to get accurate results,my advice is to use Greenify to hibernate your app,it will not drain your battery or simply just force closed after each use.
Thanks.

Thanks for your reply, but force closing nor greenify solves the problem.
It's weird since the GPS is disabled but keeps showing battery running time

Probably...

Sir,as far as i know than only remaining issue related to your rom's kernel because it might happen that unsuitable kernel drains battery more faster than ever you could imagine.
That's why i only use those ROM which i think more like stable and smooth along with Awesome kernel regarding battery work.:good:
Hint:Turn off display basically for android is hibernate mode,in which phone usually in standby mode so battery remains that much as much you have seen last time or may be few percent less but not that huge as in your pic shown.
Try flashing different ROM,like for now i'm using CM11 Mustaavalcosta's kernel which is quite stable since first day for me to use it daily basis.
Give a try but make backup first.
Thanks.

Sorry for replying so late and thanks for your reply.
I've been very busy with my final exams.
The only thing that annoys me is the GPS running time even being turned off.
At the moment I fix it rebooting the phone as I don't use the GPS frequently but is very annoying.
When I have enough time I'll test other builds/kernels.
Thank you.

Weird wakelock behaviour

The battery of my G3 drains really fast since yesterday. Both when screen is on and when it's in standby, the battery life is awful.
Yesterday, BBS said that "wake:com.google.android.gms/.auth.be.proximity.authorization.userpresence.UserPresenceService.com" is causing a heavy wakelock. I googled it and found out it has to do with Android wear and fitness services, so I disabled the service causing the wakelock and any service that had "wear" or "fitness" in it's name.
Later that day I checked BBS again and then it said that "wake:com.google.android.gms/.config.ConfigFetchService" is keeping my device for hours, so I disabled that service, too.
Today, BBS doesn't display any unusual amount of wakelocks. But I still feel like the battery is awful. Now check those screenshots:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
You see that my device is awake and BBS isn't showing it. What can I do about that?
I'm on Stock V10h and my Google service version is 6.1.11.
It took me 20 minutes to create this post on my G3 (23% brightness) and it consumed 12%, I think that's really awful.

I have the same problem and tried the same things you did. This damn wakelock is still murdering my battery.
-Nexus 5, rooted stock ROM

Now I reenabled all Play Services and the wake:com.google.android.gms/.auth.be.proximity.authorization.userpresence.User PresenceService.com" Wakelock is back. The "Stay active" (or how it's called in English) is still longer than what BBS says about how long it's awake.
Now I saw something in BBS and I'm not quite sure if it's normal:
I've got like 30 of these _sensors.qcom kernel wakelocks and some other ipc000000 wakelocks. Can someone with a normal battery life please confirm if he has them too? And do you, hucifer, have then?

i have this problem and i cant solve it with disable all fitness and wearable services! **** google play services always has a problem !

I am pretty sure you can. Don't forget do disable "wake:com.google.android.gms/.config.ConfigFetchService".
If that doesn't help you could upload a screenshot of you partitial wakelocks, !aybe I can help you.
Currently, my problem isn't the wakelock caused by google play services.
Could you please do me a favor and check if you do have all those sensors.com kernel wakelocks, too?

i have that user presence service wakelock....go to system tuner - services and disable it...also disable anything which says games if u want

I'm also getting this, any fixes?

Got same wakelock with Motorola MotoG. Anybody know how to fix this?

yeah me too

I have the same issue and Google search redirects me here.
Here is the solution: http://forum.xda-developers.com/showpost.php?p=55640325&postcount=5

*alarm* / Icing / Net_scheduler wake locks

Anyone know how to fix this? I've been looking for days, cannot find a way to actually stop it, right now it's the only thing keeping my phone awake.

It's driving me crazy!

What browser app are you using???

It is safe to temper this wakelock with Amplify. Therefor, you have to install Xposed. Easy to do and works great for me

I've turned it off now with wakelock blocker in RR, however, googleplay services stayed awake for 4 hours last night even though its set not to, I used to lose 1% at night now 4-6%
I really don't get it.

Have you tried DisableService? Very usefull app, you can find it in the PlayStore for free. It simply does what it says, disables services like some of Google Services which keeps your phone awake.

I haven't, that is a last resort I guess.
But they don't seem to stay disabled anyway; it's weird. They are all disabled in RR, etc Privacy Guard, but it isn't working.
Is there any explanation to how a month ago everything was fine, nothings changed, and now it's not fine?

I've tried clearing cache, data, etc of Google play services AND google store. Re-flashed (Clean) entirely my phone, also internal storage.

I get lots of wakelocks on CM ROMs but with OOS 3.2.7 they are gone..
1h47min awake with almost two days of standby.

This is taken now..it is a new cycle, not the same as before.
Basically I really like CM but things like this and a few other issues are keeping me away from it. Flashed OOS three days ago and battery life and those tiny bugs that CM has are gone.

Yeah, mine isn't like that, but it used to be.

I managed to resolve this issue by wiping cache/dalvik then wiping data for Google Play Services from the android app settings.

Wiping cache/dalvik in twrp? and then google play services in settings > apps?
There is no wipe data in there, just cache (on google play services)

Yes wipe cache and dalvik from twrp
Settings/apps/Google play services/storage/manage space/clear all data

Okay, I'll try that tomorrow if it doesn't settle down tonight. (trying something else right now, wanna do things one at a time)

Fair enough, let me know if it works for you.
It was a PITA to troubleshoot the issue, I tried removing my Google account, wiping data for play store/Google now, disabling Google Now, disabling location services and after each change reboot and monitor for an hour. The fix I posted was the only thing that made a difference.

Battery drains fast ( + screenshots)

Hi,
I noticed lately that my battery is draining fast. Like 1 percent for 50 minutes (In the best case) when the phone is on airplane mode and I don't touch it at all.
When I actually use the phone it goes down to like 2-3 minutes to 1 percent of battery.
I don't have root at all but used my PC to gain access for Wakelock Detector and as you can see in the pic I got 30 minutes of malwarebytes (I have the premium version with real time protection)
But usually Whatsapp is the one on the top with the most time on CPU
I have a few screenshots of Wakelock Detector in CPU, Wakeup triggers, and kernel wakelock. And almost a screenshot from AccuBattery app. I hope I can get to the solution with your help
Also I heard about AKT that you can get 7-14 screen time hours with it. Can I use it on my device? (of course after I root it)
Thanks in advance

you should uninstall malwarebytes if you want battery drain to stop. malwarebytes is malware by itself
And then, you may want to tweak whatsapp, it consumes too much power

How can I tweak whatsapp?
Btw I noticed that when I close whatsapp my battery is pretty normal so I think whatsapp is the main cause. I got pretty good battery even when malwarebytes was on and whatsapp always seems to take most of the battery bt AccuBattery app.

So 50 minutes for 1% with apps running isn't bad... And I see you're connected to network with two bars on 4G is that LTE or HSPA variant like TMobile does? 2 bars is going to drain your battery because your modem is going to keep trying to get better signal.. none of your screen shots show you in airplane mode as well

I said that I tried to put the phone in airplane mode and even closed all no-system apps with greenify but even then the battery went down 1 percent every 50 minutes.
Btw can resetting the device can work?
If I will choose reset it I will unlock the bootloader and root the phone too
And I still don't know if I can use AKM on my phone with snapdragon 845 after & after the phone is rooted)

Of course no, if you'll continue to use watsapp.
How to tweak it must be described in general android discussions, I bet there's plenty of advices

Lol I accidentaly commented from another device so it's a different account. Anyway, do you think the problem appears because it's Whatsapp Plus (which has a kind of malware in it which stoles data, but still I decided to keep it because of the features) or it's like that in normal whatsapp too?
If I will root my phone I will be able to find an alternative for the Whatsapp Plus features while using the normal whatsapp from the playstore so just wanted to know if whatsapp has this wakelock problem globaly (Don't know if this is the place, tell me where I can open a thread on it if this isn't the place ?)
