android os always on 'keep awake'

Hi guys,
Got my lovely new galaxy nexus and have been absolutely loving it apart from the battery life. Its not uncommon for it to be in the red after 8 to 10 hours with only an hour or less of screen on time. Im not new to android so ive tried the usual stuff like checking sync settinga... the culprit appears to be android os. According to the battery use screen, the android os 'keep awake' time is the same as the time on battery, so about 10 hours. This seems ridiculous. Has anyone seen anything similar and what can i do about it?

When you go to battery and click Android OS - are you seeing the keep awake time here as very long? Or are you talking about the awake graph when you click the graph at the top?
This shouldn't be happening in any case. Click through all the apps on the main battery screen and see which one is awake the most. Some app must be calling some android API and keeping things awake. Worst case uninstall apps a few at a time and try to narrow it down.

If you've recently installed any new apps one of those may be misbehaving, otherwise you may need to do a factory reset to fix it.
edit: sounds like you may be seeing the same thing others are here

Its when i click android os- the keep awake is the same as the time on battery, or sometimes more. Ill double check the graph.
Its been like this since I bought it I think, but since it automatically gets the apps I had on my old phone on first boot, it could be one of them. Ive also been splashing out in the 10p sales.
So probably just factory reset and gradually reinstall things? Thanks.

Are you running stock rom ?

All stock at the moment.
xhausx - My problem doesn't seem quite the same- they're reporting a high percentage on the android os process, but for me it's more like 20% rather than 40 or so. It's more the lack of ever sleeping that's the problem I think.
I've got watchdog installed- what should I be looking for exactly?
Looking through my installed apps I realised that Flash was there even though it's not supported. I've removed that, time will tell if that was relevant!

A not for anyone else having this problem - It's early days but battery life seems better and the phone now sleeps! I removed a few items but Flash stands out as the suspect. So anyone who migrated from another device with flash installed, make sure that flash didn't end up on your nexus when it resynced apps with your google account.

I did the Google 'resync' but for some reason Flash 11 didn't transfer over. Same for Air.

Just as a comparison. My SGN has been on this charge for 1day 13 hours and my Android OS keep awake time is only 2 hours 28 minutes and I have about 45 apps installed. So if you have high keep awake time one if your apps is causing it.
I got such good battery life this run cause I wasn't using it with the screen on constantly.

That I know, but wasn't aware the sync option also looked at this. First time transfer from Android phone to Android phone.

Sorry how are you running flash?
Now I'm not sure if you checked this but in the "developer options" of the settings menu there is a "stay awake mode" and even though it says "only when powered" but could it be that is checked and working all the time?

I had this problem too, and in true IT Crowd fashion, turning it off and on again sorted it out. Problem is, now I've found out GPS isn't working on my phone. Goddamn it.

Hi,
Can you explain in more detail?
Are you saying that you had this Android OS keep awake time, but not anymore?
And you fixed it by turning off the phone and on again?
Thanks

[Q] WIFI and android OS Causing battery drain. How to fix?!!?

I have some battery problems with my ASUS phone. It spends so much energy without any reason. I have tried to change OTA ( 2.17.40.12 [no root] and 2.13.40.13 [root] ) a couple of times but still nothing. Even when I try to reset factory settings, I have no results. Another wrong indication is that it shows wifi on, but I have it off. I don't use the device at all, but I see the battery goes down 3% every 10 minutes.
plz help me

Same problem with me. I can't figure out what's causing all the battery drain and the phone heats up a lot. I have used other phones before with all bt, wifi, data on all day I have no issues with them. Only with this phone. I can only get a 4-5 hours usage time. charging takes up to 3 hours?
Anyone can clarify this? I have the Ze551ML Asus_Z00AD version 1.8ghz, 4gb ram, 32gb internal. I don't have the fast charger either

Try going into the WiFi settings to see if WiFi scanning is on. That has been known to drain battery

It's a native 5.0 problem. I'm sure everyone has this problem right now. We just have to wait for an OTA...
Best now, is that you use amplify, Greenify, and servicely to minimize wakelock

Having "Android OS" as the top consumer isn't a native Lollipop issue. I haven't seen it jump so high on my Nexus 4, which I have left on an older version of 5.0 from last year. When 5.0 was 1st ported to the G2 some kernel changes later fixed Android OS, so I believe Asus can fix a problem that was fixed by non-professionals.
Wi-Fi should also perform better too, looks like Asus' engineers have a lot of work awaiting them. Too bad for them b/c when that ZenPad and selfie release things will get worse.
"I'd Totally Hug You, If That Was Something I Did"

I had battery problems too upon purchasing, then i suddenly thought to cycle the battery, charge it up then let it drain without using it until it turns off and then charge it up until full while turned off. My battery now is much better

Mine was great until the most recent OTA. It installed on 05/31, I don't have the phone with me to see what the build number is, but I am now experiencing the battery drain. Before this OTA I would have 50-60% battery left at the end of the day, last night it died well before then.

I want asus support unlock bootloader
Tks

I tried to clear my cache hoping it would help with the battery drain. I wasn't patient and thought the phone froze while clearing the cache and restarted it. I've now read that it can take 10 minutes to clear. When it restarted it was the flashing dead android. I was able to fastboot erase cache (took a couple of seconds) and It was good to go. I went ahead and did a factory reset. My NFC didn't seem to be working, so I wanted to see if that would fix it. It may still not be working. My phone now has much better battery life. It has been downloading and installing apps for three hours now (slow internet loading ~65 apps), and I have been setting up my home screen. It is at 90%. Doing much better, like it was before.
I'm on Z00A-2.17.40.12_2050515
Tl;dr: a complete wipe helped with my battery after the most recent OTA.

My battery lasts four hours without even using the phone. We shouldn't have to jump through hoops to get something that is even usable. THIS is ridiculous.

did the factory reset restore all the bloatware for you? i want to try it but i don't want that bloatware to come back

The bloatware was back, but the battery performance is better. I removed the bloatware I could again. I haven't rooted the phone.

So non-root performs better?

I don't think so. My wife also now has a Zenfone 2. Same model as mine, the 4gb ram 64gb model, also has the most recent OTA. Hers is non-rooted as well and has the battery drain, but only if the wifi is on. We tried a factory reset and clearing the cache. It didn't help.

Actually, it is. It has to do with play services. Good for your nexus 4 but read up on the forums. It's an android issue. Every ROM I've used for my HTC one has it, gpe, aosp, sense.

Had a nexus 5 and It sounds like that native 5.0 lolly pop issue, where it as constantly scanning for 5HZ Frequency, you could try and lock it in to 2.4GHZ setting under WiFi advanced. See if that helps.

Root the phone and delete the crap with titanium backup. I did this on the latetest update and battery is better then my Samsung s5. Turn screen from auto to quarter of the way. I have WiFi and my data is with wind mobile in Canada so it is always looking for signal. Take a look at battery from today. Been off charger since 5am til 10pm.

Crazy Android System ?!

About 3 days ago the battery drain on my Nexus 5X went crazy. I found out that the "app" Android System do not let the phone sleep and keeps it awake all the time. That is why the phone can not even get into doze mode and drains about 8% per hour when the screen is off. I tried restarting the device and also force stopping the Android System. Both without any succes. Do anybody knows what to do with it? Or should I just wait if it will go back to normal? I do have screenshots, but the XDA will not let me post outside links...

Interested about that.
Ur screenshot may be useful, host them in a site like imgur and replace dots by other letters.

Well just delete the two underscores and the "dot" thing

I am having the same problem. It occurs randomly, most often when I have just charged the phone and removed the cable. If i am correct, a wakelock under the name *backup* is holding the phone awake, it might be the same in ur case. I've done a research on this, turned out this is unfixable unless you have some sort of wakeblocker, which my current rom lacks of. I tried using xposed with its modules, but it gave me a ton of bootloops and i gave up on it. The only temporary fix for me is to reboot the phone. Until it happens again. No clean flash nor anything i have tried seemed to have helped. I even tried disabling all services and receivers from Android System, no luck again. That is one hefty problem

I have exactly same problem with wakelock. It happens only after charging. Everything is OK after restart.

It has happened to me sometimes on my old HTC One X and I think it happened also once on this 5X, but it was just for about a day or so. It disappeared itself with time, I didn't do anything with it then. Now it's been 6 days, I have to charge the phone twice as frequently and neither the reboot nor the force stopping everything works. I really don't know what to do in this case. Also this phone isn't rooted yet, so I can't just flash the system again as on my old HTC... I'm still hoping it will disappear by itself asap
But do you anybody have any other ideas what can I try to do to stop that crazy system app?

same problem here...
had the phone about 350 hours with no restart and i thought i would give it a reboot..
same think happened...android system was going from 2% to 20% in a matter of hours..
installed an app called GSam Battery monitor..showed me the phone was not going in deep sleep (Doze mode) at all...
here is an attachment if anyone can understand better than me..

I posted a similar thing in the battery life thread. Very odd really as I've had the phone a few months now but it also only started with me a few weeks ago. Really can't think of a trigger for it... I doubt the April update would have been significant enough to create an issue, but who knows.

Exactly. After about 4 months of working excellently and about 400 hours without restarting, after charging it's immediately goes into this "mode" when the Android System won't let the phone sleep. Even restart didn't help me, but now after 3 restarts it goes to normal. One bad thing... after every single one charging, every time I put the phone on the charger it goes crazy again and I have to restart the phone after every cutting of of the charger... it makes me really angry when the phone is only 4 months old and even the "okay" battery life isn't that good on this phone... God I just need to find a solution, that's insane...

THIS!!!!
the phones battery life was a big "ok i can just play a bit less so i can get through the day and IF anything happens i know it has fast charge so ok"
nowadays i have to reboot after EVERY charge....
p.s.
anyone that faces the same problem but WITH mai's security update? do we have any hope that it will fix that problem?

Not sure if it's a one-off, but I decided to uninstall the game "8 Ball Pool" by miniclip as it appeared on my battery usage stats when I'd not opened it in days. Since then, even after a recharge, the phone seems to be going to sleep as normal.
I'll monitor to see how things go but perhaps it could genuinely be a rogue app. It's a little disappointing that doze wouldn't block the keep awake requests - I thought that was one of the main purposes of it.

The same issue occurs for my Nexus 5X: after device disconnected from a charger, Android System process starts to keep device awake until next restart. As I understand from comments above factory reset does not help to solve a problem. Has anybody met the similar problem with custom ROMs/kernels?

It started with the latest update I think. It hasn't happened once ever before. I hope they already know what's happening and with the May update it will be gone. I don't think there's any other solution when you don't want to flash custom ROM and stay on stock... :/ we have to wait.. :/

Hmmm, sorry for offtopic clarification... as of now I'm little bit confused about Android versioning, especially it's unclear for me: whether you mean as latest update: 6.0.1 or april security patch or model build number (like MHC19Q, which is currently on my device)?

I guess it must be April security patch. Some kind of problem in the Android System app that comes with the security patch. I don't really know in this case, but as I've said, it hasn't happened once before the April patch

I rolled back to MHC 19J. The April MTC19T Build cut my battery life in half. Android system being the top culprit. Deep sleep never going over 80%. Horrible idle drain. Would drain 15% over night while i slept. Exact same setup as before, no new apps. SOT went from about 5 hours to not even 3.

MTC19T is May update. I've updated my device to it yesterday and the issue hasn't been fixed yet: a device is still kept awake by Android System after disconnecting from a charger. @ScumDroid, could you please confirm there is no such issue on MTC19J after rolling back?

Same issue. After running it for few months flawlessly, the Android System is keeping the device awake and only restarting it solving the problem temporarily. Charging the phone again starts the wake lock..
Most disappointing is it's the 'Android System' that causing the problem. If any app/game is linked to this, it should have been appeared as the culprit but unfortunately it's that 'System'.
Waiting for solution.

Samsung users are having the same problem.
I have found something on my Samsung Galaxy S6 in regards to 'Android OS' killing the battery. It might be the same for Nexus users, I've confirmed this on a Moto G 2015 running the latest MM update and on a Samsung Galaxy S6 Edge. By latest update, I mean the April security patch.
Check this and this.

Android OS and System suddenly eating battery

Hey everyone,
So i have a stock HTC 10, no custom rom or whatsoever and the battery drain suddenly got very bad. Android OS is on 49% and Android system on 28%. Battery drained 8% over the last hour with 3 mins SOT. I've set back the phone to factory settings and didnt install anything back on it, turned stuff like the GPS location to power saving mode but nothing seems to help. Tons of forum posts also didn't help. I don't want to put a custom ROM on it for now, so i can always send it back to HTC.
One thing that i keep noticing is my CPU usage. Im checking this with the stock android CPU checker and the load is 12.13/13.28/13.68 with only the systemui active. I have forced all apps to stop once but there was no solution. This problem is occuring since mid august. Hopefully somebody is known with this problem.
Edit: running wakelock detector atm

I experienced something similar, funnily enough it was the charger cable causing it. Not sure how or why but as soon as I swapped from the faulty HTC official cable to another cheaper cable the drain stopped. Worth a try

I tried another cable, didnt solve the problem unfortunately.

I'm having a very similar issue. Battery drains way quicker in the last few months (20% in 30 minutes) just from web browsing. A factory reset didn't help me either.
I'm trying safe mode now to see what happens (hold the power button, then tap and hold the "power off" option).

Android 11 update - serious battery drain issue

Hello,
2 weeks after Android 11 update, my pixel 2 xl started to feel hot and the battery was discharging quickly. On Google help, many people were in my case, and many of them mentioned about unstalling Tunein. Which I did, then my phone stopped to be warm but this didn't stop the drain issue. What I have noticed is that if I don't touch my phone, the battery acts as normal, slow discharge, but when I use it, meaning when the screen is on, the battery just discharges at a crazy speed. It was not like that just before the Android 11 update. Anyone got this problem and found the reason / a fix ?
Thanks

I am having the same issue. An have not found a solution as of yet. I thought it may be the Pixel Launcher. So I changed it to Nova Launcher with no change.

Yes, strange. Mine gets a serious battery drain from 100% to 50% in a short time, even when I don't use it. Then below 50% it is very stable as long as I don't use it. Never experienced this before.

I have the same problem. before that, I was calmly getting 4-6h SOT After updating to Android 11 as lucky as I get 4h SOT. Mostly, however, I have 2.5-3.5 hours. The standby time seems ok, Only during use the battery disappears very fast. ? In my free time I will try the factory reset.

I think i got it...
Hello gentlemen, i got this problem with october update in particular.
So, digging in a google forum i found a user who recommended to install an updated version of Android System Webview (maybe you should download it from apkpure or apkmirror) , Carrier Services and.... uninstall Tune-in (yep... the radio app)
I don't know which one did the trick... but it just did..
I hope it helps!

Can you comment which versions of carrier services and webview you installed?

Sure, i installed webview 86.04240 and (there was a mistake in my prev post) Device Health Services 1.17.0.331553323.
Anyway, i got 2 webview updates since then... so, just install the last one... if you got auto-updates enable you should have your problem fixed by now (i guess that happened to the op).

thanks for the info, unfortunately I checked and I have exactly the same version of the application installed. the problem with the battery remains. the strangest thing is that I have no problem with idle drain, but when used with the screen on, the phone uses almost twice as much energy as before ?

I have the same problem, idle drain is ok, but whenever I use the phone, the battery drains very fast.

finally someone with the same problem. did you do factory reset before updating to Android 11? Because I don't, and I think I'll try to do it.

NO, i didn't do a factory reset because I have seen a lot of people (online) doing it without success. You can see this thread here on Google support, over than 580 comments today...https://support.google.com/pixelphone/thread/70445129?hl=en
But apparently some people fixed the problem with a factory reset...

finally someone with the same problem. did you do factory reset before updating to Android 11? Because I don't, and I think I'll try to do it.

I actually did a factory reset today but the battery drain is still there...

NO, i didn't do a factory reset because I have seen a lot of people (online) doing it without success. You can see this thread here on Google support, over than 580 comments today...https://support.google.com/pixelphone/thread/70445129?hl=en

I had the same problem and it was a new (at least to me) Google program called "Digital Wellbeing". I had to turn it off, which wasn't a straight forward proposition. I even "uninstalled" which just uninstalled the updates and they came back.
I don't recall exactly all the steps I took, but I now have my trusty Pixel 2 XL back to it's previous battery usage. Which is excellent for a three year old device.
Anyway, turn it off, take away all it's permissions, and do everything you can to shut it down. I was almost ready to root my device just to really get rid of it.

I disabled digital wellbeing, stopped the permissions, and uninstalled the update on the play store, but it didn't fix the battery drain...

A few days have passed and I can see a significant improvement. Honestly, I don't know what actually helped. some app update or maybe something I did, but there's a significant improvement.
In general, I would like to remind that from the update to android 11 my battery was tragic but only when using it, there was no problem with standby.
I was barely able to get 4 SOT hours. Now I can safely exceed 6 hours.
The only modifications I made were:
- leave beta program of digital welbing and its complete shutdown app
- disabled wifi scanning
- disabled Location service for emergency calls ELS
Since then, battery consumption with the screen on has dropped from 25-30%/ h to 12-16%/h. The phone is like new again. In addition, everything works very quickly and smoothly. ??
