No, i'm at 6%.
something you are running is causing the activity to spike.

Percentages like this are meaningless without something to compare it to. 40% isn't unheard of if you never use the phone, for instance.

I was having this issue yesterday. I installed FAUX kernel and it went away; screen: 28%, mediaserver 16%, rocket player 13%, android os 10%. Yesterday at this time my battery meter was 40% ; today 67%.
That could be coincidence and not correlation though. If you are up for the challenge, a custom kernel could help.
However, like vincent law said, it's all relative. If android os is 40% and your battery is at 95%, that's not really so bad is it...

When android os is high... It's an app keeping your phone awake 90% of the time

Reboot when you see this happening.
I've seen it once before... I didn't think to check OS monitor before rebooting to see exactly which process it was though.

I have this problem. Anyone got solutions to it?

Try disabling some location features in Google now. I found the traffic cards to give big battery drains in Android OS. Or you can check which in settings - double slide down from top > location, to see which app is using the highest request. Google play service was usually high when I had huge android os drain.

I have also noticed that at times google play services has a huge drain on the battery. I was wondering if play store setting had anything to do with it. I have mine set to " do not automatically update".

I have both facebook and google search on low battery use. For Google location reporting, I only have location history turned on. I don't know if this helps.

I start getting the same issue since yesterday.

I've also been experiencing the same issue. Started a few days ago. Checked tonight right before I put my phone on the charger after a full day of use, and Android OS had 9+ hours of awake time. It's driving me crazy and I can't figure out what is causing it.

I am so disappointed!!! I have the same bug. I had it on my old Phone (Samsung Galaxy S). I flashed 3 different firmwares on my i9000. Nothing helped. Now I bought the Nexus 5 and after one day it starts again
I went to bed with 97% Battery. Woke up and it looked like this:
It is stock Firmware with no changes. Maybe it is because of my google account? I am using the same google account for my nexus5 and i9000.

Check your WiFi connection. I don't really know why (yet) but sometimes, being connected to certain WiFi networks increases Android OS usage. This happens a lot in my college's network so I believe it's a problem with that, because it does not happen at my home's WiFi. You could try disabling WiFi in the different networks you use and check which is draining.
Hope this helps.

Yes I had this problem. I flashed factory image and enable high accuracy location AND reporting. My problem I pinpointed was Google Now NOT refreshing.
It would hang there trying to update and without location it didn't have anything to report and it would eat battery. I would force close the launcher and notice the wakelock stopped shortly, to return to Now not updating.

I found a way to prevent the Play Services and the Android System from eating my battery.
First I noticed that it was only happening, when the location services were enabled, and then I found the App Ops App for KitKat.
All I did was disable the rights for those two Apps to use location and to keep the device awake.
I'm having the location services on - and working in 4sq, Maps, etc,.. - and no more drain.
Maybe you can verify this?

Try this
My Android OS is at 3% after 19 hours.
Google services not enough to even show.
Battery 75%.
Light use 55 minutes screen time.
Google auto sync off, i sync when i need to.
I don't let play store check for app updates .
I turn location on when i need it.
I use mostly wifi some LTE
Unchecked wifi scanning always available.
Keep wifi on during sleep
Minimize battery use when wifi is on is checked.
I refresh my email accounts when i open them so it's not being checked automatically.
No battery or services complaints (Google services is so low it doesn't even register), give it a try?

The problem is definitely caused by the Wifi! I am using my College-Dorm-Wifi over night. When turning it off, the battery life is normal.
But turning off the Wifi is no solution! I don't have data so I am only using my phone in college networks
There musts be another way.

Excessive battery drain?

Hi, think im about 2 weeks into my ownership of my N5, and over tha last few days ive noticed that the battery seems to drain far quicker now than previously. For example, my phone was 100% when I unplugged it at 8am this morning, and at 12: you can see the drain with very light use. I notice android is using a lot? Is this normal?
Any tips etc?
Thanks

i also have this problem, since 4.4.1 update Android OS is draining a lot

i read somewhere this could be down to fast dormancy??

I have a new "winner" in the battery drain category - this morning, I looked at mine & "Exchange Service" is now #2 on the list when I tap on the Battery.
Can I say, let's see what 4.4.3 is going to bring in terms of fixes & breaking more ...

Well, whatever it was, a factory reset resolved It! Been running sweet since i reset the old girl.

I've been having issues for a week now with Android Os/Kernel killing my battery. Just figured out in my case, it was having the "Enable Battery Stats" module in Xposed. Been running it for a few hours and everything but this Damn Audiomix wakelock seems good

I have the same problem in my nexus 5 after updated to 4.4.3 the use of batery for Andoris OS is around 20 % higher

Incorrect/Unreliable battery reporting?

So I was charging my N5 and rebooted. As you can see, the reported battery level jumped ~25%. I am under the impression that "battery calibration" apps don't do anything, but should I try something to fix this? Or am I wrong about calibration apps?
Sent from my Nexus 5 using XDA Premium 4 mobile app

na, just use and charge it like you normally would, itll work itself out the next 1 or 2 charges. its been like that since the first day android was public with the g1, and every device after. its not perfect, but its usually pretty accurate. when its not, it generally works itself out quick. only rarely are their other issues involved.

You're going to have to supply some information from gsam or better battery stats for anyone to help you. It could be anything that is keeping your phone awake

google search would normally be up there, it also includes the launcher plus other things. you use googles launcher dont you? the play store and calandar storage is being used too often.

Did this issue appear in the last weak or so? I'm encountering the same issue, it drives me nuts.
Using same apps as usual, no gaming and still my battery drain is far worse than before. I have even disabled Google Now and Location all together.
Installed GSAM now to analyze the stats, nothing unusual in Android battery stats compared to the stats I had before.

is google play services showing up for you guys?

I wouldn't necessarily say my drain is bad, but yeah google play services did start showing up for me the past two days. I think it might be because of the google search update. Could be from the parking location feature.

the play services showed up on mine as well, 2 or 3 days ago. my phone normally sleeps better than a knocked out baby, but since the play services showed up, i see it wake every few minutes on my battery usage chart(draining some extra battery). been changing my permissions not allowing anything to wake my device, but it still does.

It could be that mine doesn't usually sleep that well that I'm not seeing a huge difference. Speaking of permissions though, I actually made it so G+ can't wake the device because I don't use it, and it still wakes it sometimes.

Try gsam from play store. And if rooted....gsam root companion as well.
Do a full charge, 100 to low....no reboots. Then print a few gsam screens. The main screen, app screen, and in app screen.... Click the drop down and screenshot time held awake and kernel Wakelocks. Also, maybe "screen" screen and radio screen.
I know its a lot, but between all these your issue should show up.
Tho....if you have terrible signal ever while on data....that will crush your battery.
Good luck!!

Yes I have noticed that now my Google play services is right at the top. I might as well try a placebo and do battery calibration. Fingers crossed lol

You're battery calibrates every time you charge it. No need to do anything else.
I'm noticing more than the normal amount of "suddenly my battery is draining" threads. Seems to coincide with the update to Google Search. I also noticed my battery draining itself with nothing being reported in the battery page last night but a reboot put an end to it as usual.

Massive drain with no wake locks

Hey all
I had a wake lock trigger that was draining my battery so I decided to try and find what was causing it. I turned off all background sync and disabled GPS. I charged my phone to full and then let it drain over night. As you can see in screen shots... Massive drain occurred with no visual signs of the cause. Anyone have an idea?

Did you get any shots of the Kernel Wakelocks and Partial Wakelocks screens in bbs? That's where you would see the culprit(s). Also, do you ever do soft reboots? Some people (including myself) have experienced increased battery drain with no visible wakelocks after soft rebooting. Doing a full reboot seems to fix it.

I checked those but there was nothing abnormal. I'd done a reboot when I flashed the kernel back to stock pa.

I've disabled wifi and it drained to dead. Going to recharge to full and see what it does off wi-fi. What could I do to see why/if wi-fi is killing it?

You can see it is draining it in your screen shots. Maybe you didn't fully disable the background Wi-Fi usage. "scanning always enabled" for example

Doesn't look like its disabled correctly. Your screenshot shows nearly 8 hours Wi-Fi.
Maybe there is a bug in your settings data.
Not sure if you're rooted or not but maybe a backup / wipe is the best course of action

Here's the current setting. I guess I can factory reset again. I'll try that after this current charge cycle.

You could try booting the phone into safe mode to see if it's a 3rd party app, though unnecessary if you plan on trying a full reset anyways.

Factory reset, no syncing enabled, no auto updates, google now disabled, no apps other than stock gapps installed. Still high android os usage.

while at first it looks high, in reality it isnt(yet). in your screenshot you have only lost 5% battery so far with light use. at this point you really cant tell what your battery will be like with use.

ahh, thats a little better, but itll drop a little more with use. while 20 is a little high, id still classify as normal. really anything up to 20% is normal. typically, after a full cycle, i see android os between 9-15%. but it would all depend on exactly how you use your phone.

i see that chrome(and chrome sandbox) is taking a huge amount of battery for very little use. 21% together, just to respond to xda..

Install system monitor from play store and check CPU freq and number of CPU's online while screen on.

As said above....use the phone normally and check when its almost drained. It will surely be much lower.
If location is on...it will probably be higher than 10% I'd guess. If so....completely normal.
