Something is keeping my device awake (and occasionally warm)

Something is keeping my device awake (and occasionally warm) - General Questions and Answers

I have an Asus Zenfone 6 running 4.4.2 (yes, I know there's an upgrade out - I tried it and downgraded again because of performance issues).
Everything was going fine until a few days ago, when I did an app update (I set the store to notify instead of update by itself, because there are a few apps I want to hold back). Ever since then something is keeping the CPU awake all the time; battery life suffers, and when I use it the phone gets warm in no time, when it took some serious work to get it to do that earlier. It also occasionally slows down. Reboots don't seem to achieve much of anything.
A malware scan with malwarebytes got zero hits.
It's rooted and I have Better Battery Stats as well as Wakelock Detector and the onboard stats in the options menu, but I can't figure out what is doing this. Here are the screenshots (note that I have BBS set to Kernel Wakelocks by API, otherwise I get a permanent "no stats collected yet" screen on the kernel wakelocks menu):
BBS: Other
BBS: Kernel
BBS: Partial
BBS: Alarms
BBS: CPU states
WD: CPU wakelock
WD: Wakeup triggers
Battery utility
Power manager utility
What do I do now?

Do you mean the screen won't turn off?

I would factory reset it if there seems to be no way to fix it. Or u can try to back up ur apps to ur Google account u r using on the phone (sync it.) Then, u can factory reset it and try to restore the data u backed up.

No, the screen turns off.
I would really want to avoid a factory reset if at all possible.

Hmm... it may be the only way, I don't have any other methods/ideas... sorry... I'll try to think of some...

Tap and show the info about Android OS battery usage. Usually if keeping the phone awake can be solved by rebooting the phone.

Without root and a lot of advanced tweaking there is only one simple thing you can do - turn off WiFi and Mobile Data before you go to sleep. Eventually as an even bigger step you can also go to Airplane Mode but obviously you will not be able to take any phone call. See what battery drain you get under those conditions.

Thank you! Thought I had to unroot my phone. Already tried rebooting but did mot work but O tried factory reseting my phone and solved the problem.

1st picture
i think dropbox is eating up your battery
2nd picture
your mobile network signal is weak, this could be the culprit
3rd picture
same as above

post some wakelocks. Otherwise this is useless.
The 1st picture it's obviously dropbox. In the other two, who knows. without wakelock stats this thread is useless

Worth rooting...
If you root go for :
- Wakelock Detector (find out exactly what caused the drain: screen / cpu)
- Greenify (hibernate apps regularly)
- ROM Toolbox Pro (disable startup and other related intents)
Since I did (I stayed on stock) : I don't have to worry about charging during the day + all lag is gone (even with 500 apps and >100 more frozen).

wakelock detector works just fine without root greenify partially

Turn off the wifi

Battery Drain during idle time

This problem only appeared for me when I upgraded to 4.4.3. 4.4.4 didn;t solve it too. I'm on stock ROM, rooted.
Basically instead of draining 2-3% over 8 hours of sleep time at overnight, it would drain about 16%. There are no wakelocks, and the battery monitor on Android doesn't reveal much... maybe Android System is draining more than usual but I can't be sure, and everything else looks normal. I really can't pinpoint the root of this.
What I do know is this - if I reboot the phone the problems goes away, for one or two days. And then for no apparent reason the phantom drain comes back. Only solution to it is to reboot every now and then. Very annoying. Anyone else has encountered this?

you gave us no screenshots, logs or anything.
how can we help you determine the issue if you give us nothing?

Sorry about that. I'm attaching a few screenshots that hopefully give you a better idea of what's happening. Ignore the media player drain as that's just my Poweramp. As you can see it seems like all the Android processes (idle time, Android System, Mobile Standby) are just a bit higher for the high drain screenshot. They probably add up and result in a much higher overall drain.
Once I restart the phone the drain becomes normal again, but after one or two days the problem just inexplicably comes back.

I am having the same issue periodically. And the ONLY solution to fix it (temporary) is to reboot. As far as I remember it was happened to me on 4.4.2, 4.4.3 and now on 4.4.4.
BBS shows nothing major. There are no rouge processes in memory (checked in terminal), CPU deep sleep is fine (another fact saying that this cannot be a wake-lock). LTE/GSM signal is good and consistent (same place all the time). I have tried an airplane mode when drain has started but it does not matter.
If drain has started - phone would loose about 20% overnight (8-9 hours) when completely idle. Normally it should be 2-3%.
So, the source of such high drain is more likely somewhere in hardware/drivers etc.
I cannot determine which part of the hardware is draining current - baseband processor, digitizer, busmux, DAC or else...
PS: so much for all that google gimmicks about battery life improvement in every new Android OS.
Speaking of which I find out that Google Services in 4.4.4 are always trying to connect to "mother ship" even if Data Connection is turned down.
Some google developer explained algorithm they use for framework communications like this: if connection is failed then double wait time and repeat until it reached max wait time around 30min.
Well, last night (7 hours), with data connection explicitly turned off through Android Settings UI, Google Framework attempted to report to "central office" 246 times! - max wait time was about 1 minute and half.
Clearly, developers of framework know nothing about Android Settings API and continue "pinging" - well, but this is another problem.

100 cookies says its simply your poor signal.
Turn data off, not airplane mode, just data for awhile and i bet your drain is half what it is now.
Or get on WiFi.
You'll still get calls and texts with data off. During this test, toggle data on only when needed then off again.
See how that works.

Nope. No Xposed (Xposed won't run under ART anyhow). Funnily I had Xposed when I was on 4.4.2 and I didn't have this problem.

Any news on this ?
Having the same annoying problem as well, normally it does not even drain 1% an hour while idle'ing and indeed sometimes (not always) a reboot does fix the problem.
Nothing to see with BBS or Wakelock detector

I am also getting this at the moment - I only noticed it since the 4.4.4 update. Overnight drainage is now in the region of 15% where it used to be around 5%.
I guess that isn't terrible but the idle time I got on this phone for the first few months was one of the great things. Hopefully a future update resolves it.

99.9 percent chance its location services. It seems to get worse every update. Try a night with it off.
If its already off. Try turning Google now, sync and put it in airplane mode.
If it is good....its one of the above. If its still bad.... Its a rogue app. A bit harder to track down.

I'm on 4.4.4 with all that off, and my drain is about 0.5 percent per hour....not in airplane mode.

Actually... I do have sync on for gmail, contacts and calendar.

We already tried all standard suggestions like the ones you're telling us again, the problem is there's a drain somewhere we cannot find.
4.4.3 had probs as well, in the beginning with 4.4.1 or 4.4.2 (don't know exactly) it was draining only <1%/hour (even with a lot of apps installed, I've greenified them)

Then its app related, or possibly carrier. Or I suppose the old "not all devices are equal.". And my reason for saying this is that many, many people still have perfectly good battery life and standby drain.
All those with the issue could have the same app or apps.
Whenever a battery issue seems unfixable....my advice is always do a complete wipe (except internal SD) and reflash firmware. Then go a day, or two and see how it is. If it seems OK....then start installing your apps...but only like 5 a day. So if your battery suddenly isn't good again, you know its one of the last group of apps you installed.
I'm sorry, but I just can't possibly imagine its just Android draining the phone. If it were like that, reports would be pouring in about this. And they aren't.
Yes, it can be work to track down a tough battery issue. But its do that work and practice patience.... Or go back to the last Nandroid version that was OK.... And stay on it. Or live with the drain. For me the first option seems most logical. Spend the effort and track down the issue until its solved.
But, to each their own. No one can force anyone to do anything.
Good luck!!! ?
---------- Post added at 12:28 PM ---------- Previous post was at 12:25 PM ----------
Oh....and after flashing firmware...turn off every feature. Go one day like that and no apps installed. Day 2....try services you like on. Day 3....start installing apps a few at a time each day.
Just wanted to be clear. When/if battery goes bad....you know its whatever you just did.

No CPU deep sleep

Hi,
I am not sure if this should be posted to specific forum for my Moto X. If so, please let me know.
The battery drains very quickly. I used CPU spy and it showed that phone never enters deep sleep, even though I barely uses it.
How could I found out which application is preventing the sleep?
Thanks

Like Sewrizer said, search for a wakelock detector on google play store and lock your screen for some time
It should show you which app is causing this problem

I have Moto X with 4.4 and no root. It looks like Wake Lock Detector would need root on 4.4. Is that right?
Thanks

betterbatterystatus is also a good app that helps with analysis of battery drain.
Anyway in the case you know you only need to check wakelocks, but I would still recommend BBS for you (of cource, BBS can analysis wakelocks as well)

@redhonker
BBS did not work in 4.4.4 in non rooted mode.
It happened to me on Moto g. Some culprit app drained battery. So i used DS battery and greenify together.
DS battery- Slumberer mode (This forces deep sleep i guess)
Greenify- Allows you to shut down nonsense background apps.
Now phone is back to normalcy. Again CM battery doctor listed some music app as "Fast draining" I uninstalled some.
As general advice:
Disable auto sync and poll frequency of your email and other apps and get back your motto x. Enjoy
Press Thanks if helped.

I thought greenify needs root as well. Will try it.
This KitKat change is really bad. I don't know why they want to prevent users to know more about their battery usage.
What is CM battery?
Thanks

Greenify has a hack for non root. You can enable hibernate feature from home up button for screen lock pin enabled devices through experimental menu.
For non - pin screen lock devices go to experimental menu click "automated hibernation". This will enable hibernation after screen off.
I prefer home button scroll up menu for " hibernate + lock screen ".
CM battery doctor was previously KS battery doctor. I just use it to kill apps and know battery % left in status bar.
Remember no battery saver app is useful for non root devices because ability to control is much lessor.
Rooted battery savers can limit cpu usage, kill apps and prevent again from Android picking up.
Greenify an exception beyond 4.0 devices.

This post will benefit all not just @OP
To identify bg apps that suck your internet and battery just install No root firewall and check access log. Uninstall those apps that keep pinging servers outside for adverts etc.
https://play.google.com/store/apps/details?id=app.greyshirts.firewall&hl=en
Eg: Nova launcher access advertisements on avg of 4/sec. Do decide which one is best for you.
You can even control system apps like Motorola updates etc.

CM/KS battery doctor

As you see CM reports higher battery available time than DS battery saver.
I suspect former (CM) is more publicity driven and not sure about its performance. While DS is good.

This does not require memory intensive app or root as it comes pre installed on your phone. Enjoy.

I run Mobiwol and block all apps I don't think need internet access. Plus AdblockPlus to remove advertisement trafficc. (I wish I have root then I need only one app).
Without root on 4.4, how much these can do?
I installed GSam. The frustrating thing is that most of application usage is by Android System and Kernel: 9 and 5 out of 34.
Thanks

Thanks for all the pointers.
With a few tries with GSAM, I was able to identify 2 rouge applications. Surprisingly, one is Google+. Since I don't use it, it's uninstalled.
I also recently moved to a different spot in office. The data signal apparently is bad from time to time. So I used llama to turn off data in office and wake up every 10 min to check for message.
This allowed me to go through the day without a recharge. Still not happy about battery life but that's ok for now.
Thanks

Try the Deep Sleep Battery Saver app mentioned earlier. Should solve your issue, since it forces deep sleep!

what on earth is keeping my phone awake? wakelock detector screenshots included.

I recently installed wakelock detector to help me save battery life with greenify. Looking at what it says it seems my phone never goes into deep sleep. This screenshot only shows the past hour and a half as before that I greenified things that looked like it might be causing the problem, but it looks the same now as it did before, 0.0 of deep sleep no matter how long I leave it, but none of the listed wakelocks seem to be that long, so I can't figure out why my phone wouldn't be deep sleeping.
Its a rooted Sony Xperia e4 running 4.4.4
Any thoughts?

You should also check Settings -> Battery -> tap on battery graph to open History details. There can be some dependencies between 'Awake' data and other data. Or you can post the screenshot of it here.

Hi, Sorry it took so long for me to respond, I was hoping to get a screenshot from a period where I hadn't touched my phone for longer but I kept forgetting at night time. I notice this time it actually says my screen has been on the whole time (though I never used it in this period at all, and when I picked it up the screen was off) So I have also included a screenshot of the screen wakelock page. Frustratingly, a lot of the things on the cpu wakelock page are already greenified and I manually hibernated them before turning the screen off, so not sure why they are still causing issues.
Either way, none of it adds up to the time awake

I posted a reply on this earlier but it seems to have disappeared. Anyway, I installed betterbatterystats and it showed that *backup* was keeping my phone from sleeping.
Google suggests it isn't altogether unconmon, and following some instructions I found I disabled back up, cleaeed dalvik cache and enabled back up again
So far its worked brilliantly, hopefully it stays that way.

Just an update on case anyone googkes and reads my solution above, it didn't work. Restarting my phone makes it go away for a little while and my phone gets plenty of deep sleep even in only a short space of time, but then *backup* comes back and its all over again. I can't keep restarting my phone every couple of hours. Maybe turning backuo off permanently will help, but then I have no backups, so hardly av good solution.

Hi,
*backup* is a wakelock from Google's Backup service. Wakelocks are so crazy because it regularly backups your data (such as Contacts, your Play Games' progresses, WiFi passwords, app data, etc) to Google's server. Disabling this equals to no longer having up-to-date backups.
You could actually disable the automatic backup, but make sure you backup your data periodically.
It's better for me to use BBS instead for checking for wakelocks.

So I've been browsing for the past 2 hours on wifi and these are my stats.
Battery: 2200 mAh
SoC: Extremely Power Hungry MT6591
Brightness: Adequate

Now at 35%, the phone was being used pretty much constantly (chrome, a movie in mx player, imgur, 2 hours on whatsapp, light CoC)

Blue Blood Modified Battery Profile (SOT) for L Speed + GovTuner
NOTE: This profile and the configurations for GovTuner is entirely based upon the need for more SOT or 'screen-on-time'. Performance improvements are not the 'primary' objective, but there are some.
Name: Sorry but I couldn't make up a better one. LOL.
This profile will try its best to give you a better screen on time taking into consideration there will be some decrease in performance (some visible, some not).
Installation Instructions
Part 1 - L Speed
1. Download the .zip file attached.
2. Open it with any file manager/archiver and you should see the profile file.
3. Goto your SD Card -> LSpeedBackup (create folder if it doesn't exist) and paste the file inside the .zip there.
4. Open L Speed -> Backup -> Restore: Blue Blood.
L Speed's done.
Part 2 - GovTuner
1. Visit GovTuner's XDA thread and download the latest zip file.
2. Flash the zip file and install 'Terminal Emulator' from playstore.
3. Open 'Terminal Emulator', and type 'su' and enter. Grant the SuperSU request and you will now be in a root shell.
4. Now type 'govtuner' and enter.
5. Choose battery profile by typing '1' and touching enter.
6. After activating battery profile, enter 'i' and enter '2' as the value.
7. Now you can press the 'X' on the top right hand corner to close the window.
GovTuner is now all setup.
You are pretty much ready now. Enjoy your extra SOT!!
I SERIOUSLY RECOMMEND USING AppOpsXposed, Greenify, Amplify and Powernap with this to get rid of the idle drain because in the end that too translate to a better SOT. :highfive: (The below results are obtained with the help of those applications too)
My phone which is an extremely battery hungry thing needs to be charged atleast 3 times a day to last from morning to night. With this I've managed to get away with just 1 charge for 14 hours (4-4.5 hours of SOT vs 1-2 hours).
Please do reply back with your experiences. I'm waiting for some happy faces. :fingers-crossed:
Also criticisms. :angel:

Hey, thanks for sharing this! Much needed for my phone htc desire 816 (a5dwg) running lineage 7.1.1 and at any rom, it is hungry. I mean literally I've purchased a new original 2600mAh battery for this reason. Still the problem persists. Today only, I've charged the phone to full and kept it on airplane and silent (took the phone to school ), and found that after 3 hours, battery is 20-25% reduced. I'm a little noob that's why I'm asking you that "what are the steps that should be followed / apps to be installed to maintain the battery like yours
Thanks in advance ?

Glad I can help. Something is keeping your phone awake all that time that its's not going to deep sleep. That's mostly Google to blame but let's start with the basics
Before that don't call yourself a noob. You got a custom ROM running, most people I know can't even do that.
To fix Idle Drain
First find if you have Idle drain.
Install Better Battery Stats and open it, grant root etc. Now plug the phone to the charger and hit refresh. Now unplug the charger, turn the screen off for a minute or so.
Now turn it on, you should see the device state. If it says Deep Sleep 0%, then the below things can help you.
Disable background Wi-Fi scanning.
Your phone scans for WiFi even when you turn it off. The steps below are based on my Lollipop 5.1, but I believe it's the same on 7.1 too.
Goto Settings -> Wifi -> The three buttons on the top right -> Advanced
There disable 'Network Notifications', 'Scanning Always Available' and 'Keep Wifi awake during sleep'.
Greenify
You must already be using this.
As a rule of thumb, greenify any app which requires an internet connection, those keep waking the system over and over again. Just make sure you don't add any core system apps.
If you have Facebook's app installed, remove it. It's the biggest battery hogging app ever happened (i don't agree that's made) in human history. Use it in chrome. Or any wrapper apps from Play store: Metal, Friendly are a few options.
If you have xposed installed,
Powernap
Set it to endurance mode and that's all. Whitelist amplify, greenify and lspeed. You can whitelist more apps later if you feel the need.
Amplify
This is a must in reducing wakelocks. Unfortunately I can't write the whole procedure here because it's been done before. Check this.

Still, every phone is unique. After following that thread, IF your device still isn't sleeping (after trying the below too), try blocking more wakelocks. Do a search if you are not sure of a particular wakelock. It will take some time, but it will be worth it.
AppOpsXposed
You can disable some of Google's data collection and analytics whatever stuff using this. Follow this nice thread. It helps massively.

If you have managed to get that deep sleep in BetterBatteryStats almost 90% of the time the screen was off, then congratulations you have fixed your Idle drain.

Glad I can help. Something is keeping your phone awake all that time that its's not going to deep sleep. That's mostly Google to blame but let's start with the basics
Before that don't call yourself a noob. You got a custom ROM running, most people I know can't even do that.
To fix Idle Drain
First find if you have Idle drain.
Install Better Battery Stats and open it, grant root etc. Now plug the phone to the charger and hit refresh. Now unplug the charger, turn the screen off for a minute or so.
Now turn it on, you should see the device state. If it says Deep Sleep 0%, then the below things can help you.
Disable background Wi-Fi scanning.
Your phone scans for WiFi even when you turn it off. The steps below are based on my Lollipop 5.1, but I believe it's the same on 7.1 too.
Goto Settings -> Wifi -> The three buttons on the top right -> Advanced
There disable 'Network Notifications', 'Scanning Always Available' and 'Keep Wifi awake during sleep'.
Greenify
You must already be using this.
As a rule of thumb, greenify any app which requires an internet connection, those keep waking the system over and over again. Just make sure you don't add any core system apps.
If you have Facebook's app installed, remove it. It's the biggest battery hogging app ever happened (i don't agree that's made) in human history. Use it in chrome. Or any wrapper apps from Play store: Metal, Friendly are a few options.

Sorry, I've switched to stock to check battery capabilities but still problem persists
Battery droppes from 100 to 83 in 30-35 minutes

in govtuner change the gov to ondemand, i guess u use perfomance.

What can I do, I got a notification that L speed us eating my battery...but if optimized will not work as it should right?
Today update my Rom and got error. Not working because if use 3th party kernel ini.t emulator...but I'm not using one.

What ROM are you using?

FreedomOS for oneplus 3t.

@Adithya FRK
Choosing battery profile from govtuner is the same as choosing it from Lspeed CPU menu, right? Or is there some significant change between the two?

Both are the same. See post #2 of GovTuner's official thread here - https://forum.xda-developers.com/an...mod-gov-tuner-project-29th-june-2016-t3407828
But don't enable both of them at the same time.

After 1 whole month of tweaking with various functions of L Speed, finally found a combination to improve the battery even more.
BlueBlood v2.1 (Download link in Post #1)
Tested on L Speed Beta from Play Store.
