[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.

Don't worry you won't lose any important data.

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] Samsung Galaxy Note 10.1 2014 Temperature , is this normal?

I have just purchased a used Galaxy Note 10.1 2014 and have had it switched on for 2 hours tops, I have noted that the temperature of the Note on the top right hand side is very warm indeed. I have downloaded the System Tuner Application from the Play Store and note that the CPU temperature with no open applications is varying between 45 and 55 degrees centigrade and when for example I watch a video this can go up to 70 degrees , can I ask is this normal for one of the 2014 10.1 Notes, I have a 2012 / 13 version and it never goes over 45 Degrees whatever I throw at it task wise?.
Can anyone let me know if this is normal please as I've read that the tablet shouldn't exceed 45 degrees with all apps running?.
Thanks.

1. What build number are you on?
2. Are you using a microSD card with pdf's on it?
3. Are you rooted?
There have been reports of this happening due to S-Finder trying to index either the internal memory or an SD card. If 2 is yes, try removing the card and check the temps again.
If that doesn't work and 3 is yes, try greenyfying or freezing with S-Finder with TB and recheck temps.

On Android 4.4.2 and build Number is KOT49H.P600UEUCNI1
I am not Rooted and No SD card is in the Machine.
I have only today purchased this machine, temperature is currently 48 degrees but reached 72 degrees 10 mins ago whilst watching a TV program online ?
Any further advice appreciated, should I ask for a refund please?.
As it does seem rather hot?.

It is, not sure about the refund, it is an issue with this model. Try turning off S Finder first

Yeah mine doesnt have option to turn off s-finder either. I'm on 4.4.2 in the UK [emoji53] .... odd.

Could anyone possibly let me know a solution to this problem please?, is it directly related to android Kit Kat, is there a solution to it without losing functionality or having to root the Tablet please. I'm in the UK also and as the previous poster has agreed you cannot stop S Finder.

From my point of view, you'd have to root to have more options.

Yes, the only problem with rooting is that you lose functionality of the Sky Go Tv application here in the Uk. And also use the S pen which I find very useful and was the purpose I bought it for, can any of you guys post your CPU temperatures under average load please?.

On mine, normal temp around 35-45deg .C for normal usage (include watching video). For gaming possible up to 65 max. If your cpu is high, check for one of the app is stucking doing something. Since you don't have root, it's hard to pint point, but let start with put device in battery saving mode and turn off wifi and see if that help. By turning off wifi, this will shut down all the apps that try to sync data through the internet. Also, go into settings -application-> running apps and see what running the most. Last case, try a factory reset see if that help.

I believe Greenify can now hibernate some apps/services in non-rooted devices?

[TIP] Solve SW2's constant conecctions-disconnections [ROOT].

Well guys, I have a short tip to solve that common problem on the SW2 (as far as I read). I have only tried it on my smartphone, but it worked and you could try just in case. You´ll need root for this. Don't worry, if it doesn't work for you, you can go back to normal easily.
In my case, my phone killed the smartwatch service and then it "revived". So I put the Low Memory Killer (LKM) (not sure if is that the English name, in Spanish it's called "Prefijos de Limpieza de Memoria") into a lower value that it had (depends of the phone). After that, my disconnections problems disappeared
To change it, I recommend use Kernel Adiutor, an awesome kernel tweaker.
I hope this works for you. Tell me your results. Peace

I think this do not happen on modern phone with 1 Go or 2 Go memory.

This is interesting and I would like to try it. Which low memory killer value did you change? I assume you changed 'hidden applications' but I thought I would check.
Thanks,

But yeah, the smartwatch service is just that, a hidden app, so if you just want to change hidden applications it should be enough.
I would change empty apps a little too because when the smartwatch isn't doing anything, my phone thought the service was one. (?)

Thanks, I have Kernel Audiutor as part of my ROM anyway so it is easy to do. I was thinking of playing around with the LMK after reading your post, which preset profile did you finally choose? I actually use two Smartwatches:
An SW2 is attached to the handle bars of my motorcycle for a variety of reasons
I sometimes wear a Cogito Classic
I have many more problems with random disconnects with the Cogito than the SW2 but I will play around.
I also have the canonical problem of the phone randomly disconnecting from my car's Bluetooth and this could be the cure for that ill as well. Of course, it is very difficult to prove the absence of a problem like that.
Thanks again,
Fred

This is the most annoying issue on this phone. It happens seldom, and the only solution is to restart, but sometimes it doesn't work at all.
I can't find a trigger to it, as I open the same apps each morning in the same order: endomondo, sports-tracker, biko and strava. All of them use the GPS and usually work ok. But suddenly, last week GPS dated started to malfunction and first no satellites in view, then after reboot the problem on the screenshot arises: many satellites in view but no fix.
I tried GPS test and GPS status apps to clear GPS cache, but it doesn't work at all. But sometimes just opening this apps kind of "un jams" the GPS and it gets a fix.
Any idea if this is an Android issue, a Huawei problem and if there is a solution to it?

Bad news, it's back again.
It's not even cloudy.
I've noticed it happens more often in the mornings, at night GPS locks almost immediately. Also, a reboot fixes it most of the times. It has to be something related to system. But what?
Enviado desde mi P6-U06 mediante Tapatalk

Hmmm, i still get problems with the speed but not as badly as i used too, i always leave my gps on so its a warm start, it can take up to 4 mins to download the catalogs from the sats with a cold start, i am afraid the gps will never be perfect ob this phone the best thing is tp try to manage it as best you can, leave it on with gps test and let it download all the catalogs, this will take about 15 mins then always keep gps on, this will help it retain the catalogs, it wont use much battery mine doesnt, this will reduce the lock time, i would also change the setting to autonomous in the setting instead of network assisted and try that.

That's weird ?
I haven't this issue, maybe it's an app which is responsible for that. Go to the developer options and search for "memory" or "Running services". There you will find the apps which are running in the background and it will show you how much memory it need.
If you can't solve your problem a Hard-Reset might work. I think it's a software problem because my phone works very stable with Pie and without such memory problems.

Have you checked battery optimize and modify draw over apps etc settings?

I have the same damn problem with multitasking... Tried everything, went through all battery settings, developer's settings and such. Tried every option. Multitasking is simply impossible on Mi A2 Lite (Pie 9.0). Apps turns off instantly after I leave them. Optimization for each app is turned off, Adaptable battery turned off, Battery saver turned off, also. Nothing helps; So sad, and it seems there is no solution for this.

Xiaomi is famous for theirs memory management algorithms. They are too aggressive, leading to premature app killing.
