[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

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.

ResurrectionRemix wakelocks, any help?

Okay:
I have narrowed down my wakelock issue a fair bit. The only ROM (my favourite rom that I actually want to use, lol)
Resurrection Remix wakelocks - the ones I get are below:
*alarm* Google Play Store
Google Play Services *alarm* and "Icing"
Gmail "Icing"
And any apps open even Facebook, Instagram, Google maps - they all just stay awake.

Google Play Store and Google Play Services are being held awake under Settings > Battery as can be seen when I press on them, they're awake for hours.
I've tried turning them off in Privacy Guard
Now; I've tried BJRR, RR official, RR Sultan-ized, Old Naman RR build
All of these USED to work, then out of nowhere they've done this wakelock stuff. Also, I've used gapps packages old and new, pico.
I've tried the exact RR build I had before and gapps package and this was how it used to be:
Now; it's always 0.6-1.2% and I have no idea what has changed to cause such issue.. I've tried the wakelock blocker in RR too.
If someone can fix this issue; without me having to dowloand apps, and so on (I mean,. it worked before, so why should I need to download apps/change things?) I will send you money. Seriously, cos this is driving me nuts

No help you evil lads.

Still trying.
I've noticed in Settings > Battery
And then the list of usage.
GMAIL, Google Play Store, Cyanogen System/Android System, Google Play Services
All "Held Awake" for hours.
Why? and what can I do

Still nothing.
tried again today, same thing.
Android system stays awake when asleep.
*alarm* (com.android.vending.Google Play Store)
also that, and every app stays awake when sleeping for like 20-30% of the time, and if i go to bed for 7 hours, they are awake like 4 hours it says.

One last try before I go to bed?! lol.

Are you using amplify?

Nope, never have.
The phenomenon is unexplainable, happens on all versions of RR now where as before it didn't - doesn't happen on Nuclear, CM, OOS, etc.

I have had the *alarm* wakelock in numbers > 1000 within 3-4 hours on OOS. I found a reddit post which said that these were like placeholders for blocked wakelocks and alarms.
Now I have removed amplify completely and I get 0.5-0.6% idle drain on OOS lite with Greenify only. Ironically with amplify, the drain was about 1% per hour

RR has an inbuilt wakelock blocker right? That could cause it if I'm right.

Well you can try to flash GApps again but best would be a clean install.

Standby Drain Problem - can't find the reason

Hey guys,
i recently got a HTC 10 cause Ive dropped my Galaxy S7 in water. (insurance)
Besides that the HTC is noticeable faster, the standby drain drives me crazy.
HTC 10 @ Viper ROM with elementalX Kernel
1) What the hell is "BatteryServiceUpdateStats_3"? in 16 hours, it causes over 600 wakelocks per hour. Maybe this is my draining problem? In the Battery Historian screenshot you can see, that my phone is constantly doing something because of this process.
2) Why is there an "unknown" entry at "Kernel Wakeup Reasons"? 287 per hour... wtf?
3) In GSam you can see, that "Android OS (Kernel)" is (always) the top process...

Thankyou in advance, i can't find more tools to analyze this strange behaviour....
Edit: so i checked Battery Historian with active/inactive WiFi... and what do I see? Yep, much less wakeups from BatteryServiceUpdateStats3 & generally less Wakelock time..... why???

You might have this problem. I have it too and it's infuriating. I've pretty much stopped using WiFi unless I'm charging. Really spoiled my experience with this phone.

Do you have "ok google" hot word detection enabled? That was causing me some serious wakelocks, and I had forgotten I had enabled it to play with, it's usually not something I use or want. I'm still not sold on Google Home being a good thing because google knows everything there is to know about me. I'd rather some devices not know the pitch of my farts or where my girlfriend hides her phone when she has no pockets.
My battery life was still pretty decent though, amazing actually considering it was staying awake and always ready for my next command, but I know with it not running it will be much better.

You could have shown more infos from Battery Historian
If you wanna know what a proper Standby looks like, you can take a look at mine:
http://forum.xda-developers.com/htc...ark-thread-t3376159/post68929720#post68929720
but yeah.... there are a FEW known issues with HTC10 Standby....
A) 4g might cause more Batterydrain than 3G, but that was an early issue, and mainly on American Carriers.
B) WiFi does have shîtload of wakeups you cannot control. ExKernel has wlan_rx and wlan_ctrl divier options, set both to 8 (maximum) might help.
C) If you have Access to your router, maybe deactivating IPv6 can reduce WiFi Battery Drain.
To your 3 Questions.....
1)Already answered here:

Power Nap [Xposed Module] also blocks them. But it doesn't matter. Because they do not wake the phone, they happen when the phone gets awaken by something else.
Check this out (With Power Nap enabled and What's app excluded)
As you can see, almost no Userspace Wakelocks:
As always Google Services is the only thing you simply cannot shut up, no matter what
But yeah, the Problem is on the Kernel Level....
You see a Normal Wake due to an UserSpace Wakelock:
And one that's happening due to Kernel:
So as long as you have these Kernel wakes, the BatteryServiceUpdateStats_3 will activate at the same time. Batterylife itself is not really affected.

2) Wish i knew what these Unknown Wakeups are.... Wish i knew!
3) i don't really like GSAM, i prefer BetterBatteryStats.
What does the Battery Historian say about CPU usage by App?

Hi, did you find any solution? same thing is happening in my lenovo k6 power but only when i use jio sim. if i don't use sim there is no battery drain in standby. check my attached screenshot of battery historian.

Hi try to reinstall other kernel, im using CleanSlate v2.2.0 now so far superb. and also install htc bost to sure not eat so much RAM usage.
Last time using elemental kernel but im lazy to configure, therefore battery drain quite fast even in standby mod.

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 ?)
