[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

This amount of Power Manager Display and Wakelocks especially are to damn hi, can any1 help me, I'm on HTC10 nougat, Ice, clean slate.

@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.

[Q] juice defender's extreme profile 10% battery after 10 hrs?

So I haven't got a chance to root yet, but i got juice defender on extreme profile and I got 10% battery left after 10 hrs and I haven't even used it that much. I remember before just using the free version I was getting more. I use wifi over mobile network when possible and I make sure wifi is off when leaving the house, but I was home all day. What is everyone else getting and any help? Here is a screen shot.

Obviously screen brightness is the most of it, but do you think thats accurate? I have it on auto? What should I put it on? How many hours are you guys getting with or without juice defender?

I average around 12hours with 2.5 to 3 hours of screen on time. That's without any kind of battery saver. I have 4g on all day, auto sync on, full brightness on all day. Usually leave my house at 2 to work and when I get out at around 11 I have around 60 to 70%.
Sent from Flip's S3

I get typically 3-4 hours of screen time, it seems like, but I'm not doing the most I could.
The total time really just depends on how long it was idle - I've gone over a day, but also used up battery much faster. I typically charge once a day, 16-ish hours from last charge.

I am thinking that you have some other apps running in the background that are polling for notifications. I am also betting that you are not getting very much Deep Sleep due to wakelocks. The only way to really tell is to use Betterbatterystats from the market, but that is a root app, so no joy there.
Only thing that I can offer is the simple approach. Check your Auto-Sync -is it synching all the time, do you have Maps/GoogleNow running all the time, Locations/GPS, Manage Apps>FC apps that you are not using, maybe take a look at your JuiceDefender preferences (I have used JD+ for years and love it-Don't use JDExt though), Lots of downloads/surfing (see Browser is up there on your list),...
Really without Root, it would be hard to diagnose what is "really" eating your battery.

Why not the extreme profile? Right now I have jd-ultimate and on extreme profile. No good? It basically has all my data off completely. Then I enabled the apps that I use in configuration. This then only allows data for these particular apps but only when I open these apps up for use. I appreciate the help and by no means second guessing you. I just dont understand why the jd plus not using extreme profile is better than jd ultimate using extreme profile. By the way I turned the brightness from auto to all the way down and it seems the battery is a lot better now, but I haven't used the phone as much as the other day so idk.

No, no you are fine. I don't think you are 2nd guessing me at all. I just don't use Extreme because I use the Customize option myself. Plus I have JD+ and not JDUlt. If you want more about my set up, go to my battery guide and post#4. It has my specific settings and how JD really works.
Also, just because you are not actively "using" the app, doesn't mean that it isn't running. If you say set up Twitter to poll for notifications every 15mins, well, that is a User Preference which will take priority over JD's Preferences and will open up your radios, thus causing battery drain.
My main point above was that you need to look at your background processes and see what is running. I am betting that you have some things that are running that you are not aware of and which can be shut down (i.e. media scanner, picasa,...) Get Betterbaterystats from my guide or the market and it will tell you what is running/eating your battery and also what is causing wakelocks and preventing Deep Sleep.

Betterbatterystats is really worth it, I have the apk from here, but plan on buying it next pay cheque.
It will tell you where your battery power is really going. It can be a bit to figure out for a noob, but I just Google things I wasn't sure about.
I think that controlling things myself is the most effective thing to do since I know what I really need I can Erma of functionality and where I can compromise.

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)

Only fixes when reboot.

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.

Battery Saving mode not working as expected in stock OxygenOS

Hi,
I got my OnePlus 3 nearly 4 days back from the date of this post and I have been experiencing issues with the "Battery Saver" mode. When enabled, I still get all the notifications and from applications like WhatsApp, Facebook, etc. leading to battery drain issues and poor user experience.
Check attached screenshot for more details. I was in battery saving mode and still got a WhatsApp notification, and with 95% of charge and it shows me 4hrs of standby time.
Please guide me at the earliest if this is a problem with the device(H/W) or the operating system, so that I can ask for replacement if required.
Current OxygenOS version : 3.2.7
P.S. I moved on from Nexus 4 to OnePlus 3

Your OP3 likely is fine. You probably have an app not behaving well. I would try a wakelock detector or some battery savings tips posted in the forums. You could also try greenify and/or the kernel governor profiles listed in the news section. Some members have their device so well optimized they are getting 7-10 hours SOT. I am sure with a little more reading you will come across a solution that works for you.

I also moved from N4 to the OP3 and am loving it. I get 7+ hours of SOT.
You can do a factory reset and check. You can also calibrate the battery once by allowing the phone to reach 0% charge and shut down automatically. Then charge it to 100% while it is off and when fully charged, boot up the phone.
Most probably your issue should be solved.

Thanks for sharing,
I too loved my rooted Nexus 4.
And I think that I am getting a better battery backup on my new OnePlus 3 since past two days after using Greenify and by calibrating phone's battery(I was avoiding Greenify to benchmark this phones performance ).
What's still bugging me, is that after doing some comparison tests on other phones, when the "Battery Saver" mode is ON and I am on "mobile data" I still get application notifications on my device, which is in contrast to how other devices behave.
Behavior was similar when "Battery Saver" mode was ON and I was on "WiFi".
Devices on which I tried were OnePlus X, Moto X Play, Moto E3.
I have checked the battery optimization option, nothing there. I hope I am making sense !

Hi,
Thanks for sharing,
Yeah I am regular follower of XDA and used some nice optimization apps(greenify, wake detecter, leandroid, xposed,etc.) myself earlier on my rooted Nexus 4.
Whereas in my new OnePlus 3, what's bugging me is this :
After doing some comparison tests on other phones, when the "Battery Saver" mode is ON and I am on "mobile data" I still get application notifications on my device, which is in contrast to how other devices behave.

Devices on which I tried were OnePlus X, Moto X Play, Moto E3.
I am starting to believe that this should be a software bug and not hardware issue, but wanted to be sure and learn from the community here if they have faced something similar.
I have uninstalled some apps to get a better feel for this devices performance while its still in warranty.
I have also started using Greenify to get a better battery saving experience, which I was avoiding just to benchmark my device's performance.

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.
