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

Frustrating Battery Situation. Let's figure it out! help??

I never had a good battery on this phone since I bought it (second hand)
my average SoT is about 2hrs for around 15h uptime daily
I formatted many times trying to fix it, changed roms, kernels, governors, interactive profiles. nothing worked
I thought it was the battery. so I changed it by myself and it's the same, or even worse than before (lol)
Yesterday I removed my google account to see if I have too many services running. and still have 25% active drain and 3% idle (ex kernel manager stats). too much
I don't know what to do now.
1) someone suggested me to watch wakelocks but I need help on that because I don't know how exactly and what look for
2) do you think that could actually be the device? is it possible that lg could accept it as defective? I don't think so. they should be able to repeat my issue, and we know that isn't possible since battery usage is very personal
3) do you have any configuration you suggest me to try.....? maybe I'm missing something
Thank you for your attention, I hope that this thread will be useful for everyone

Personally, that's just about right for me. I think I get about the same SOT if I had light usage. Usually though I get 3-3.5 hours SOT with around 12 hours off the charger. I top off for an hour on the charger once a day everyday and just got used to it. A lot of times if people have longer​ uptimes, doze was working overnight​.

Have you tried to flash it back to the stock nexus image? (Return it entirely to stock) That would be my first step in nailing down battery issues. It will completely wipe your device, but it rebuilds all the partitions and updates everything to the newest images. (Assuming you've downloaded the newest release from google). Then you can run it on pure stock for a few days and monitor it. My n5x isn't the greatest either with battery, and standby drain is brutal on nougat no matter how you configure it, but I usually get at least 4 hours of sot. It also depends what you have running. If you're using bluetooth and location services, google assistant ect, it follows the battery is going to drain much quicker. If you flash the stock image, you need adb and fastboot installed. There's lots of guides here on XDA.

@throcker, my advice: try a ROM, stock or PureNexusc, clean flashed, without GApps, any Sync off, GPS and mob data off. You should get 5-7h SOT.

I wiped completely several times, downgrading to 6.0, updating via ota, flashing lastest image, with and without encryption
I use bluetooth (g watch)
I'm very experienced on flashing and stuff, tried everything by myself, this thread is a desperate thing

You all wanna know what's going on now?
battery 23%
Google play services 18%
whatsapp 11%
screen 10% (1,12h)
and I don't even have google account.

@throcker: GPlay-services means, you flashed GApps. They are busy in the background without account.

That's an extreme exception. You're on the far right side of the bell curve in battery life. I bet I can't even let YouTube play for 8 hours straight to get that kind of SOT. LOL

oh $#!T.
but...I'm really bounded with google services stuff, I sync my pc chrome, keep, docs, maps....
I think I'll give this a try, but there is no way I could run that setup as my daily.....

Same here and I don't really know what to do... Really frustrating and I don't even have BT, NFC and GPS toggled on!

Use BettetBatteryStats to check for wakelocks during the night to see if something is keeping the phone awake. Then I also recommend either unplugging the phone from the charger right before going to bed or setting a custom reference point to check how much the phone drains during idle. I had the problem that my phone was draining about 2.5%/h in idle even with nothing installed, airplane mode, everything off and so on. This turned out to be a hardware problem which could only be fixed by replacing the motherboard. So check if you have the same symptoms that I did.

Battery Question

Guys,
i need some help. Over the last two days, my battery has just gone. The attached screenshots are from earlier this morning. I'm really not sure what's causing this. I lost 11% in under an hour and my phone was telling me it has 4 hours of battery left. I haven't installed anything new in the last two days.
I've tried using better battery stats in the past. I'm not sure how these apps work. I noticed my cell service isn't that good but I'm at home, always on WiFi. Can someone point me in the right direction? This phone is not even two months old.
Thanks in advance.

I highly advise you to turn aeroplane mode on and enable WiFi calling if you have it. It saves so much battery! This is whilst your indoors of course. Keep your brightness below 40, disables location when you don't need, disable auto update and sync behavours, disable NFC and Bluetooth if not being used. Disable animations via developer menu.

Your screenshots don't seem to show how much battery Android OS is using and there's nothing battery draining in what you did include, so I don't know that anyone can really do a lot to help you beyond offering very general suggestions.
What Rom or version of Android are you running? If you are running stock did a monthly OTA update install recently? It is that time of the month.
It's possible you have a rogue app but there's nothing showing up in your screenshots. It's possible that Google, Facebook or some other app is getting sync errors. Where you would check for that would depend on what OS you are running.
You could contact Pixel Support but my guess is that they would have you try a factory reset, which might be your best course of action based on the limited information you have provided.
My battery percentage currently shows 61% 1 day and 7 hours left, so you definitely have something wrong.
I would personally start with a factory reset. You could also run the phone in safe mode for a while and see if the problem persists. If it doesn't then the issue is likely a third party app.

When I had my battery issues, I factory reset and just ran stock for a couple days. It turned out I had to RMA it due to a bad battery. Phone was dying between 20-60%. I would barely get 1 hr SOT

Your screen was on for the majority of that time. And that 4 hours left means at the current rate you're going you'll only get another 4 hours. That is nothing more than an estimate and it will change all throughout the day based on you're use. Try letting you're battery drain all the way to zero 3 times. This should calibrate the battery. Try monitoring it after that.
And a side note. Use you're web browser for Facebook. The Facebook app has been a known battery destroyer forever.

I:m running Pure Nexus ROM with the Elemental kernel.
Thanks for all the responses everyone. I will try to drain my battery and see if that helps.

I had this problem. I went in and disabled all of my Google apps. I then went back and re updated them in the Play store After that I did a restart and I haven't had one since. I also recommend not having a battery case as both the Mophie and ZeroLemon both caused huge wakelocks for me. Cheers. ?

Terrible battery life since Android 10

Since the latest update of Android 10, my phone will not even last me a day. I've asked Google Assitant if my battery is bad and it told me it's fine. But I can do 30 min of light new reading and it's dropped by 20%, previously I could easily get an hour of Reddit and reading and it would drop to 90-91%.
I've tried many things, like clearing cache of Google App and Google Play Service but it still drains. I have no apps running the background that I see are taking a lot of resources.

Try a custom kernel; there are a number of good ones out there. I use caesium.

I'm using latest: 10 factory image, EX kernel, twrp, and magisk.
Today I was at 2hr 55 min with 47% remaining, and my overnight drain is about 6%, which are both about the same as what I was getting on 9x.
IIRC "wi-fi and BT scanning" (location) were turned ON by default when I switched to 10, so I turned them off. Not sure how much, if any, additional drain that might cause.

Yes...this ^^^; I am experiencing the same as well...
I noticed I used to have such excellent battery life on my 2XL, but no longer... I used to use it pretty hard (SOT plus apps like GPS or streaming music/video), and still have a good percentage leftover at the end of the day (15-20%)....
I'm unsure what, if anything specific, might be causing such the drain, but I "chalked" it up to the new OS version....maybe it's inadvertently attempting to sense off-screen gestures for all i know (which would be an understandable loop with that being a Pixel 4 particular and makes sense of the drain)...
Just some basic info on my device: October patch, Magisk v20, custom kernel: Caesium (successor of the legend Flash kernel), AOD is enabled, manual brightness but usually at 80%-ish, “Saturated” color scheme, Dark theme enabled (in both Display settings and in Developers settings), “Optimizing battery use” is enabled for most apps….

How old is your Pixel 2 XL? Google Assistant also says my battery health is fine but I definitely have battery degradation and I'm not surprised after 2 years.

Thanks my battery is good. Although it's only been 10 months. I hope dark mode is supported in more apps specially WhatsApp, Chrome and Facebook. That will help the battery even more.
October update is really buggy. I didn't like it at all

My battery life is about the same. But my phones takes WAY longer to charge esp if i am not using a google quick charger.

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.

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. ??
