I just got my Nexus S on April 12th, don't have many applications installed. My battery only lasts about 10 to 12 hours and I haven't been able to figure out why. I've noticed other people have much longer battery life than this. I have 3G and mobile data disabled and use only WiFi and that too only when I'm home. From the "About > Battery use" place I discovered that Display uses around 50%. I had my brightness settings set to auto always. Today I fully charged it and after an hour or so it was on 83%! I didn't even touch it. It sucks to have an awesome phone and to not be able to use its features because of fast battery drain! please help.
Check email sync ...
Check always sync ...
Check weather sync ...
Check facebook sync ...
Check all syncs
Mine can last up to 2 days
But I don't sync like crazy ...

my brightness is on 0% are you using any white wallpapers?
set everything to black if you can.
what about apps that auto sync? set the interval for sync to be longer
Whatever you're doing, you're doing it wrong.
Provide as much detail about apps and running services and someone can help you.
The battery will last longer if you don't use it...just saying.

It is about using your phone, clearly you can't get that through your head. I'm not going to keep defending arguments against someone who can't understand simple concepts. Consider yourself blocked, so it doesn't happen again.

Cool, you're just doing me a favor because I'm getting sick of you mocking me in every way possible.
Agreed with ScooterG. Pretty much johnz had a thing against me because of a previous battery thread yesterday.
How do I change sync settings? I thought all syncing was disabled when I turn it off on the widget (the one with wifi, bluetooth, etc.). I have sync turned off from there always and enable it when I'm in a WiFi range.
@zephiK I have a dark wallpaper, I'll try setting brightness to zero.
I unplugged around 8am and now its 12am here and the phone is down to 86%. only 4 hours later. And I didnt use much during those 4 hours. No texts, no calls and just 1 email after I turned sync thing on and used WiFi to browse this thread. Thats all I did. Battery use shows Display using 69%! This is not normal right?

Well 86% after 4 hours is a great battery life! 96-86=10% It gives you (4/0.1) a theoretical battery life of 40 hours !!!
On the battery manager click on the graph to see what causes your battery life to decrease very fast: GPS, Wifi, Awake or Screen on.
I also noticed the battery meter app used quite a bit of energy you should remove it, remove also the task killer it may drain you battery as well.
I'm trying out the suggestions in this thread right now. They seem reasonable. It might be useful for you.

Yes! Thats great battery life! You see, after I made my first post I read somewhere that you should drain the battery completely and then do a full charge. So I kept on playing with it until the phone shut down and then plugged it in before I went to bed. I made the second post after I woke up and didn't realize that at that time the battery life has increased. I havent charged since that post and been using it, the battery is now at exactly 30%. Been running for 17 hours and 45 minutes.
I guess my problem is solved
I have been obessing over my battery stat page and am trying to figure out what exactly "Android System" is. It is usually consuming the highest percentage of battery power. I have tried everything to figure out what action exactly makes Android System get added to the battery stats page. I have disabled everything, every radio, syncing, deleted all widgets. I hardly have any apps as it is. It just seems rather inconsistent because sometimes Ill check the page after making a call and will find that Voice calls has consumed a small percentage of battery and Android System isn't even on the list. Other times I will take it off the charger and make a 30 minute call, but when I check the stats page 70% battery was used by Android System and only 3% was Voice Calls.
Can anyone tell me exactly what triggers Android System so I can make sure I cut down on its battery usage in any way possible

What would you guys do?
Android system will occasionally use CPU as well, as shown in the following screenshots. Also! My good buddy let me see his Droid x recently. He had 42% battery life left and android system had only taken up 4% of that.
I'm pretty upset about this.

If you asked me I would say all your values are a little screwy. Do you even turn the screen on, on your phone and use it? If you use your phone the Display should be by far the most used. To me it looks like you physically use your phone very little. That is why Phone idle and Android System seem to be the higher numbers.
Guessing you have many accounts syncing in the background. One of the biggies for Android System. So its not that Android System is using so much, the rest of the processes are using so little.
Oddly enough the same thing started happening with my phone recently too.
@Agoattamer
The system wouldn't eat most of the charge in less than 8 hours in normal circumstances. Also about your question concerning accounts, while I'm not seh6183, personally I only have my email account synchronizing and the very same thing happens.
Something is causing the CPU to remain awake, in my case stuck at 800MHz.
The factory reset will most likely solve it, but it'd be best to find the culprit to just try and rectify a specific anomaly rather than reinstalling the whole system.
Has recently any core Google apps been updated? Email, Maps, anything?
I do agree that in 8 hours of non physical use your battery should not be going dead. So I couldn't sleep last night and I did some google searching. Here are some things I found out.
Do you have Googles Goggles installed? Seems it may have a bug where it keeps the camera on even when the phone is supposedly asleep.
Seeing that seh6183 always has his wifi active maybe it has something to do with wifi. I found this from Juri's TechBlog
couple of days ago I finally got the eagerly awaited system upgrade to Gingerbread on my Nexus One. The update went pretty well, although some Nexus One users reported about problems with the updating process. The only thing I noticed is that Dropbox didn't work after the upgrade.
A re-install solved the issue. All-in-all Gingerbread is great. Beside UI enhancements it feels also faster than Froyo. However, after trying it for two days now, I noticed a substantial increase in battery consumption. By looking at the system battery stats (Settings -> About phone -> Battery use), Android System was listed to consume 23% of the battery .
Apparently the problem is a bug in Gingerbread version 2.3.3 (you know there is 2.4 as well) on how the system handles the Wifi adapter. If you go into your Settings -> Wireless & Networks -> Wi-Fi settings, press the menu button and click on "Advanced", you'll see a menu entry "Wi-Fi sleep policy". Gingerbread seems to have a problem when that option is set to "When screen turns off". While that may sound to be the most energy-saving option, the bug turns it into a battery killer. If you switch the option to "Never", the Android system will only consume ~3% in the battery stats.
Obviously, in addition to this, the best battery saver is to just turn Wi-Fi off when you don't need it . Caution, if one of the future updates fixes this problem (which I strongly hope), you have to set the option back again.

Something I didn't see but killed my battery on my windows mobile phone was instant messengers. Do you use any apps that are for instant messaging.
Found this thread also talking about the same bug with wifi
http://code.google.com/p/android/issues/detail?id=15057
So it seems that if you (cmdr001) also are a full time wifi user, you may be affected by the same bug. Check your wifi sleep policy and adjust your settings to "Never".
Install a battery monitor app from the market or spare parts to see what is using your battery. Install Juice Defender to stop all that excessive useage.
Excellent find!!!!!
Just switched the sleep policy to "never" (which ironically I've always used until very recently). Ill return with results after about 5 hours. The only thing is that I'm on android 2.3.5 not 3.3 so we will have to see if the bug was affecting me.
I also don't have Google goggles. And to the above poster, my phone regularly went into deep sleep so it wasn't my CPU that was staying active.
Oh and I've been using watch dog to look for rogue programs for the last 24 hours. I haven't got a single alert.
Sent from my Microwave
I guess the first question should have been what ROM were you using and to try a different one then. Needless to say it still has 2.3.3 components in it. And if you recently changed that setting then my bet is thats the issue. Goodluck.
Watchdog may alert you if you are using too much cpu at one time but I don't think it will let you know what is constantly using the cpu.
Ok there's a glitch somewhere in the battery tracking. I just checked it and android system was consuming 12% battery. I placed one 17 minute phone call and re checked it, I then had 57% android system consumption.
No way.
I'm using a cm7 nightly and I'm about to flash the stable version with a different kernel. Ill do a full wipe as well.
Sent from my Microwave
You could check your wakelocks.
After recharging my battery to 100% and wiping the battery stats, my android system consistently uses 2% of the battery, while the display sucks up around ~40%.
I haven't completely figured this out yet so you'll need to be patient with me.
Basically there was a new update for Es Task Manager which made it a whole lot more advanced, giving you control over not just running tasks but what tasks autostart at startup etc.
Anyway, i was playing around with it and decided to kill everything that i dont use and prevent it all from restarting for a laugh. The one thing i added to the "ignored list" - a list of apps that it never kills - is adw launcher.
Now im not sure which particular task it is but there must be some piece of LG software which is seriously eating up the battery because with all the ancillary background crap killed and just usual phone use (calls, texts, emails, some browsing, one or two photos and a pair of short 1080p 2D videos) and then a whole nights sleep with 3g on the whole time i have mamanged to retain 71% of the battery after 16 hours, 56 minites abd 30 odd seconds.
Im gonna investigate it more to find out what i did but so far this looks promising in helping fix this horrible battery life some of you have been getting.

Most LG apps are blockable, latest update however made com.lge.omadclient (the update checker) semi unblockable but blocking that breaks settings app so have to live with it until that's fixed.
But yeah, seems weird that the phone uses 2/3 of the power that the screen requires for Phone idle (% used divided by time) guessing there are a lot of things that currently are using too much juice from the battery for no reason, hopefully this will change with CM7
Third party apps can still access the setting even when the settings app itself force closes. I had to find a way around that previously when i removed the fonts app and discovered that display settings no longer worked. Most of the "battery optimization" apps allow you to change most of the settings you might need to if any part of the menu becomes innaccessible.
I noticed that omadclient seemed to be running forever and not achieving anything. Also com.lge.hiddenmenu is a suspect for using a bunch of battery.
Im hoping that some serious efficiencies can be discovered with the wifi adapter too cuz it seems to absolutely ruin the battery life even when just idle.

I am on V10F today. I got the update yesterday night.
I have unplugged my phone at 07:20 this morning. I have made some calls, recived and sent a couple of texts. 3G data was always on, FB, Google+, Twitter, Gmail, Market, Weather App were always syncing. I have played a couple of games. Some surfing etc. It was a very ordinary day for my phone.. It is 22:44 now and I have 61% battery left. I think it is doing quite good.
I am using Automatic Task Killer and deleted my corporate e-mail account from the phone. E-Mail app of LG is a true disaster. Havent tried Touchdown yet, probably it will solve the case.

Screen brightness is always automatic.
Today, I have 77% battery left and it has been 7 hours after unplugging.
Data, 3G and Sync was always on. I havent played any games yet but used 3D camera which also consumes a lot.
I've got something incredible for me:
2 days, 2 hours, and 44 minutes. And I still have 8% remaining:
Details:
- Default launcher.
- 3G always off.
- Wireless is one when needed, first day it was on for about 4 hours of usage, and the second day for about two hours. During that time Sync is on, checking emails, using twitter app, reading Whatsapp messages, surfing by Tapatalk, youtube 3D, and downlading some videos.
- Taking some 3D pictures and some 2D/3D videos.
- Showing off 3D videos for friends.
- Playing a little bit 2D games before sleeping, about half an hour.
- Using TwinPic app and viewing 3D pictures.
- Receiving and making some calls.
Note that I have 14 3D app,42 default app, and 120 downloaded apps.
What helped me is Advanced task killer app, I used this configuration:
- Auto kill level: Aggressive.
- Auto kill frequency: When screen is off.

hey guys,
i made the experience, that the LG battery widget is one of the major problems for me. I just deactivated that and couldn't believe that this helps so much.
would be nice if you could test it for you and share your experiences.
check if there is a battery widget running. usually they drain battery. have optimus 3d and with everything off (wifi, bt, gps, no sync, no email, no skype, default task manager shows 0 apps running) from durning 8 hours of standby mode got from 90% to 6%. charged till 97% unplugged from socket in 20mins lost 3% battery. after 2 hours 50 was left.
removed LG battery widget from the desktop. charged back to 100%, unplugged. 2 hours passed: 99%.
seems that was the issue. hope it helps someone

As soon as I got my phone and set it up, I disabled all the AT&T bloatware in addition to google+, twitter, ypmobile, etc. Phone was always running great, but I kept wondering why I could never get over 3 hours screen time.
Fast forward to this morning....I re-enabled every app that I have disabled, and now I'm sitting at 3 hours screen time with 35% battery left. Didn't change anything else.
So I'm not sure why disabling apps caused a huge battery drain (I thought it would help with battery), but it did for me.
Might be something to check out if you are having battery issues.

You said as soon as you got your phone set up you did this. That brings a few things to mind:
1) It sounds like it was your first or second battery charge. You need to fully charge/discharge a couple times before the battery's properly configured and you'll experience the device's full battery life.
2) Being that you just set it up, auto-sync would be working overtime for the first-time sync. You know, pulling in all your contacts, emails, calendar events, facebook everything, and so on, causing a higher-than-normal strain on the radio (either wifi or LTE, doesn't matter) and CPU.
Now that your battery's calibrated and your first-time sync is done with, give'er a full charge, disable the same apps again, and let us know how that goes.

I mean when I first set up the phone I disabled the apps. I've been using the phone for a few days with the apps disabled, so I just re-enabled them this morning.
This seems counter-intuitive. Until a few more people report similar situations I'm reluctant to believe that it was one of the apps being enabled/disabled that caused and fixed the problem.
I personally disabled all the bloatware that was possible and I've had phenomenal battery life. Sounds like your phone just needs to go through those first couple charge cycles to get the battery going properly.
yeah mate, have to agree with the guys above. i disabled all the ATT crapware and haven't had any problems. sounds like you've got a wake lock somewhere. download CPU Spy from the market and search the forums for Better Battery Stats to find the culprit
I've got quite a few things disabled and I hit 34 hours on a single charge earlier today. Sadly I had to reboot so the uptime chart only shows 24 hours.
After seeing this I've re-enabled all of the HTC bloatware (facebook, twitter, etc.). I have a feeling that my crappy battery life may have something to do with HTC's Sense software somehow trying to interact (with their widgets and whatnot) with my disabled apps. If that doesn't change anything, I'll try to enable AT&T's bloatware too and see if that makes a difference.
Hi,
The battery life of my Nexus 5 has taken a dramatic hit since the 4.4.2 update. I think the culprit is Android System but the GSAM battery graph seems to suggest that the culprit is Android OS kernel. My Nexus 5 is on 4.4.2, unrooted, stock ROM and the build no. is KOT49H.
In short, my phone does not seem to have a wakelock issue but I can't verify because 4.4 does not allow wakelock access without root. It sleeps fine at night and in daytime when it is not in use. I only lose around 5% or less overnight with 2x battery turning off the data connection and only turning on data connection once every night. The problem is the Android System which drains at least 17% (sometimes 25%) of battery everyday and routinely sits on top my of battery usage chart with or without me actually using the phone. My usage per charge is typically around 6-7 hours with around 1 hour 45 minutes screen on time. I had extraordinary battery life before the update to 4.4.2 (lasting more than 1 day with over 3 or 4 hours screen on time). Now my battery life is completely shot. The battery graphs attached already represent one of the better days. Some days the Android system will drain at 25% or more. You will note my phone relatively slept fine without draining at night in the first 7 or 8 hours and then the battery drain started to take a nose dive after I woke up. I feel that whenever I start using the phone (with the screen being turned on), the battery drain will occur. My observations are as follows:
1. I use LTE but the reception at my home and work for LTE is not good so the radio jumps between LTE and H+ from time to time however I do not think the radio jumping contributes that much to the drain. The drain stays the same even when I am at a place with good LTE reception. I use wifi at home but i cannot connect to wifi at work (which sadly is another issue). The wifi is always off unless i use it at home. I do NOT have wifi scanning in the settings. I have wifi battery optimization on. I never use bluetooth.
2. My google now is off. My location setting is completely off with no location reporting etc..
3. My Google + auto back up is off. I do not use Facebook, Facebook messenger, Instagram, snapchat etc. I mostly use Feedly, Whatsapp, Gmails and look at stock quotes every day. I seldom take pictures, videos or listen to music.
4. I only have one widget dashclock widget. I have removed feedly and stock quote widgets from the home screen but they don't seem to affect my battery usage that much.
5. I use Automateit but only have a few rules such as setting vibrate on weekdays etc.. I do not have any profiles which are related to GPS or location which i understand would drain battery. I also use Dynamic Notification, Light Flow, Lux, Nova Launcher, Notification Toggle and the memory in general is always below 65% in the background. I also use 2x battery to save battery which is set at switching off data after I turn off the screen and it will only turn data in the background every 10 minutes.
6. I have tried safe mode and 9 out of 10 times the Android system drain remains the same. The only way to lower the Android system drain (albeit temporary) is when I turn off the phone and plug it in for a charge, then turn it on when it is full and still plugged in. After I unplug it, the Android System drain will lower to say 7 or 8 % but it will slowly creep back up to 20% within an hour or so.
7. The CPU usage overlay routinely has 9 + readings on the top when the screen is turned on (but with no app running). I think it means very high CPU usage.
8. I do not think Feedly is causing any problems. I deleted the app and the drain remains. I also do not think GSAM is that useful as pointed out by another member here. It points to one app. You delete that app and then the drain remains it will point to something else.
9. I have been using Greenify (non-root) but it does not seem to help with my battery drain as the drain might be caused by system apps or processes within the OS.
I don't know what else to do and this problem has been troubling me for more than 1 month now. Please help !
Update on 24/2/2014:
I have given up and factory reset my phone. After I reset my phone, the apps were installed via Google Play automatically. I also switched to ART. It was fine initially for at least one day. The apps were there but I did not use or enable most of them as I wanted to transfer all my data and tweaked the settings in one goal. I mostly just used Feedly, Whatsapp and Maps for navigation. Even with Maps and high accuracy GPS on, the Android System would go below 10% even though it would temporarily increase to say above 20% during navigation. This morning, I thought the battery seemed ok so I enabled Lux, Dynamic Notifications, Lightflow, Automateit, Nova Launcher and restore the settings to most of the apps.
The Android System drain came back within 2 hours and hit 25% of the total battery drain. My phone's battery dropped from 100% to 40 % in less than 5 hours and the screen on time was only around 1 hour! I never did any battery intensive actions. The most was turning on the phone to check my battery and whatsapped less than 10 messages back and forth ! Since the drain re-appeared, I have turned off completely the location setting, Google Now, sync for Google Plus, auto-backup for Google Plus. I have removed all widgets and disabled Dynamic Notifications, Nova Launcher, Light Flow, Lux. The drain still remains the same at 23% or more.
This is driving me absolutely crazy and I am sick and tired of spending so much time and energy on sorting out the cause for drain (and to no avail!) I spent a lot more time on trying to fix the phone than really utilizing the phone for my benefit !! I just sent an email to the Google tech support and hope they will help instead of sending me generic self-help sheet. Thanks all for listening and trying to help. I am just really disappointed with Google this time.
Use bbs to get wakelock info.
Feedly has got to go too

Thanks for your reply. My N5 is not rooted so I do not have access to wakelock stats anymore.
I have removed Feedly but the android system drain persists.
Not a lot that can be done without knowing the cause. Consider factory reset?

I am hoping I don have to resort to factory reset and can wait for the 4.4.3 update but I guess my patience is running out.
Thanks for your help.
My missus' LG-P880 has exactly the same problem. Just started happening one day. It seems to be wakelock locator alarms according to bbs but there doesn't appear to be any reason for it. Its been driving me mad too. Luckily tho she's rooted so using app opps i disabled Google services location and it's kinda helped

Did you try another kernel ? When I changed to franco kernel, my battery life is better.
having weak LTE signal kills the battery but it should not be this bad.
Maybe you should try a factory reset and see if the problem still persist, if not then you have an rogue app somewhere.
You can use the process of elimination.
Start with disabling Dynamic notifications and Light flow as those have high potential for battery drain.

Restart your phone in safe mode, and see the battery drainage...maybe it can help you.
It seems good for me

I had this same problem the other night. Get app ops starter from the play store. In there turn location off in Google play services and android system. Note, this may impact other apps. I don't use any that I need location for so it works for me.

I had a similar issue as well. For me I turned off a couple things and it really helped:
1. Turned off Cerberus, I believe checking location too often or incorrectly or something.
2. Turned off Account sync for Play Newstand. Noticed when a sync would occur, it would hang on Newstand for much too long which I think was waking device and keeping device awake during it's long syncs. Everything else would only take a min or two total.
3. Set G+ photo sync to only sync when on wifi and charging.
4. Removed Yahoo Weather app. Noticed yahoo weather app staying alive a lot too.
5. Removed Whatsapp. Probably unnecessary really, but any of those messaging/weather/location apps that I don't use often (if ever) I removed to make sure they weren't checking location in the background.
So far, I'm at 78% battery today when I would have been at around 30-40% usually, so that combo has made a huge difference.
It's going to be different for everyone I think, but basically just make sure you don't have any excess apps checking location in the background. And at least for me there seems to be something wrong with Play Newsstand sync hanging for long periods of time.
Yea... Even i had the same issues... Latest version killes ma deep sleep mode nd also some of a rules disappeared....
I was having similar issues and was able to narrow it down to syncing Google Services...
I found that often times Google Drive would get hung up when syncing in the background and chew up my battery.
What Google Services do you have set to auto-sync? I would narrow it down to the ones you only really need to have synced in the background and have the others sync up for you when you open them.
Also, in regards to your LTE/H+ signal, have you tried to flash another radio to see if there is any improvement? A poor signal can have a pretty significant impact on battery life as well.
Lastly, as mentioned by another user, Better Battery Stats, though requiring root, will make it a lot easier to track down the culprit of the issue if it indeed a rogue app somewhere.
Try different keyboard. I've a suspicion that latest Google Keyboard is the culprit.
I was having some unexplainable with BBS (no locks, etc.) battery drain. Which can only be resolved (though temporarily) with reboot.
So, I installed alternative keyboard (Swype in my case) and using it. So far, second day I don't have battery drain.
Update
Please refer to the OP for update. Thanks all.
battery after reset
After a second factory reset, I did not install a lot of the apps which I suspect have something to do with my drain - including Swype, Dynamic Notifications, Nova Launcher, LightFlow, Task Manager, 2x battery, Lux, Notification Toggle, Dash Clock, Automateit. I have also set my location to device only with no location history and history. I have also disabled Google Now. I have not restored my photos, music and videos to the phone yet. I have disabled sync for Google Plus, Google Drive etc.. I have also disabled auto back up for Google Plus. I am on ART.
The battery life (with around 25 % left) was around 6 hours 30 minutes or a bit more but with close to 2 hours 40 minutes screen on time. The screen was the biggest draw. Android system comes in second with around 13%. This is obviously better than before where I managed to squeeze maybe a hour or 30 minutes more but with 2x battery turned on in the background. I mostly used the phone for battery checking, whatsapp, Feedly, web surfing. I played games for around 20 minutes. I was not on wifi most of the time. Is this battery performance normal?
Thanks in advance.
Replacement offer by Google

I have reset the phone three times. After the third attempt, the battery drain for Android System would go back up to 20% plus. By the test of elimination, I thought I narrowed down the possible culprit to Light Flow and Dynamic Notifications. I uninstalled both of them but the battery drain remained 20% plus.
Google was willing to replace my device. I asked them whether the battery drain is likely a hardware or a software issue or a combination of both. They said (to my surprise) it is hardware issue. It seems they have come across quite a number of similar cases. I always thought it was a bug within 4.4.2 or in the google apps such as Google Play Services etc. and could be fixed by a patch or something. The phone also means a lot to me as it was a gift from my gf. I just don't want to go through the hassle of replacing the device if it is a software problem but I guess I am running out of choices unless I decide to wait for the update. What do you guys think?
It's definitely not a hardware issue. If you Google it there's threads all over the place with all different makes and models of phones having the same problem and no one can figure out why, apart from it definitely seems something to do with Google services (GmsCore.apk)
Your best option is to root your phone and use app ops and turn location access off for every app that doesn't need it. (pretty much everything apart from maps and weather apps)
