So I thought I would talk about the battery life between JB and ICS. Right now, it seems I am getting less battery life with JB. Anyone else feeling the same way?
I can't get 2 hours of screen time since JB, I was 4+ with ICS, doing the same things daily. Or is it just me?
Same here... around 3.5 hours on WiFi. Where I was getting 5 hours. not just you. Something interesting though. In log cats... it seems to being freeing up memory ALOT. GC_CONCURRENT happens after just using the phone for a simple task such as opening the settings.

Currently I am getting 5+ Hours on JB with stock OTA with all original but I just switched to Franco Kernel and underclocked so I have yet to see batterylife with tht.
EDIT
-Wifi is always on for me and im constantly searching the web, youtube videos, 3d applications, games etc..

Possibly result of Project Butter. The increase in frame rates etc, and what you have seen in log cats, is probably putting more strain on the battery than did ICS.
The increase in performance means decrease in battery I assume.

The problem with that is... my kernel developer... was delving into my logcats and couldn't get his phone to spit the same results. I also notice an abnormal amount of heat which is result of it staying in 1200mhz too often. So something IS overworking the CPU question is... WHAT?.

Ok so here are my results. Some screenshots will follow soon.
screen brightness around 20%
mobile data OFF all the time and only 2G connection selected
Wifi ON about half the time
ALL sync off
I used the phone mostly for browsing and playing youtube videos, just a little 3d gaming
In these conditions, I got 4 h 53 min screen on time, in 10 h 30 min total on battery charge.
Using all stock JB 4.1.1
I am totally in the dark here. Is this a good result or not really?

Not very stellar if you never have mobile data on and only connect to 2G, with WiFi on 1/2 the time, and no sync. I'm not at all surprised by those results.
With JB : +3h
Better battery drain than ICS for me
I'm in stock JB, all day with data connection (3G), screen 50%, no GPS, no Wi-Fi (or sometimes).
I never got more than 3 - 3.5 h of screen time on a full day use of the phone. That's exactly what I get now, nothing has changed.

I'm assumning you are not overclocking the CPU. However, it varies from build to build. In my experience with 4.0.4 ICS yakjuzs build the CPU was set at 1200 MHz which casued the phone to overheat and the battery only last for 6 hours. Yakju build ICS and JB the cpu is set at 700MHz which made my battery last for 16 - 18 hours. Now there are other factors too, for example screen brightness, 3G will consume battery power, brightness takes the most of battery power. So check which build you are using and see the CPU settings, I use quadrant standard app and saw the settings under system information.

dude... you are confused. The processor that is mounted on our gnex has the stock frequency of 1200 mHz. Having it at 700 would be a serious and probably dangerous underclocking
Yep same problem ,
with ics I averaged about 5hrs of screen time
with jb only 3hrs =(
With ICS 4 hrs + screen time and
With JB 2 1/2 hrs.
Became worse.

Hi,
I just got my Galaxy Nexus, flashed with AOKP build 18 and i gotta say that the battery life is unacceptable. It drops 10% in less then 1h while the phone is sitting there doing nothing. Wifi, bluetooth, location services, GPS are off. All background apps closed.
It lasts about half the time my iPhone 4 does and it is a year and half old.
I see some people showing examples of how their battery last for more then 20h but all these are BS tests as they leave the phone on standby all day or have some very light usage.
Is there a real fix for this? Am i forced to drop another 50$ and buy Samsung's 2100mh extended battery?
btw i tried setCPU also to lower CPU to minimum when in standby but doesnt do much. I want a solution that will enable me to use my phone, not something that makes it last 40h in standby and then kills it in 2h when i use it.
please help!
So everyone that posts four hours of screen on time is bullshitting? Did you know the first 10% isn't even that accurate? If you're on Verizon turn off LTE. If you're on GSM and you don't get three hours of screen on time you have an app that is killing your battery. It is as simple as that.

Try toggling Bluetooth on and then off, then grab CpuSpy from the market and check out if the CPU is pegged at a certain speed.
Some builds of ALL the custom ROMs have had issues where the phone wont sleep correctly, high %-age of Android System process, etc.
I disagree that its silly to talk about idle time on battery, because idle time is the closest we can all get to apples to apples comparison. We all USE our phones differently, the closest we come to using them the same is when they are just sitting there idle (not quite exact because some people sync data, some people only have 3G, etc, but a lot closer than person A playing games for 3 hours at a clip vs person B browsing for 3 hours)
I *still* havent seen anyone come up with a template like setup to report battery life. Like you said it does me no good to know someone dropped 3% "overnight" without knowing how long "overnight" is, if they had 3g/4g/Wifi enabled or even disabled completely, sync on/off, etc.
Personally, Ive seen 1.5%/hr drop with my phone idle. Running AOKP b19, LeanKernel, interactivex governor, undervolted (-75 mA at each level from 180 mhz to 1200 mhz), 4G on, BT on, GPS on, sync on (1 gmail account).
I imagine with all that stuff running 1.5%/hr isnt half bad. Screen on time isnt incredible but its not bad, but again my screen on activities can (and probably will) be different than your screen on activities so take that with several grains of salt.

It's not the first 10%, it's all the time.. it drops for about 10% or more every hour. Less then 3h of screen time.
I'll give cpuspy a try and see if some app is killing my battery.
I used AOKP rom because most of the people in the thread were saying that rom fixed their battery issue but for me it made no difference.

Yea somethings not right. Off charge at 8am and its 4:30pm now. Got 61% left at time of this writing and been using it quite alot. Typically have about 75% left about this time.
I just use an AOKP like yourself and a custom kernel. I'm on the phone like every 15min reading emails, SMS, word feud, twitter news, Facebook, Gmail.

It's actually 2000 mAh not 2100 mAh.
You can use a custom kernel such as Franco Kernel. New version came out today and includes more battery improvements (according to changelog!)

As you can see, if my screen is on the graph drops, when it's off the graph flattens out and the battery barely moves. I used to be sick to my stomach of the battery life until I realized it was because I wouldn't put the phone down and always had the screen on thus killing the battery.

Just a word of advice. Whites consume more power on AMOLED screens. You'd probably maximize your battery a lot more if you went back to a "Ice Cream Sandwich" feel or at least apply a black themed MIUI.

I had something similar and it was recommended to me on these forums that I log out of Gtalk.
Before people come out and say it makes no sense - it doesn't really matter if it does or not - it worked for me. I get a full day out of a charge now, which doesn't really matter because as someone said above it's all relative. What DOES matter is that my phone is now sleeping properly, so the battery doesn't drain when the phone is idle. That's the part that wasn't working on my phone.
If you feel so inclined, give this a try and see if it works for you. Just log out of all Google talk accounts and see how your battery life is - you'll know within a day if it's helping.
Have you flashed the new radios yet?
You can also try different kernels and see which one works best for you.

I think MIUI is pretty much at the same state as CM9. Just lots of work needing to be done since ICS revamped Android in so many ways.

not quite.
can i preface by saying that there are two types of Gnexus's out there? the SCH-i515 (CDMA/LTE Verizon) and the GT-i9250 (HSPA+, AT&T).
The 2000mAh is for the HSPA+ version
The 2100mAh is for the LTE version.
i see a LOT of bad advice on these forums here.
my best advice to you (from one Verizon Nexus owner to another), is to keep at stock 4.0.2. Root it, and apply a custom kernel. Only apply custom kernel if you feel that you're still not getting decent battery life for a whole day on 4G stock ROM/kernel.
As far as I know, Verizon Nexus owners' max on-screen time with 4G enabled all day is about 3 hours MAX, and thats if you disable everything else but LTE, with very low brightness settings, and on extended battery.
imo, the next 4.0.3 or 4.0.4 update hopefully will mitigate some battery consumption issues.

You were on wifi the entire day.
You are using the HSPA+ version of the Nexus. HSPA+ version gets better battery life.
Try being on HSPA+ the entire day with wifi disabled. you will not be getting 4 hours of battery life on-screen time.

Most of the time I was on wifi, but not all.
But fair enough, I will test on 100% without WiFi. However, we don't have HSDPA+ unfortunately. Only HSDPA or 3G.

sounds dumb, but are you sure you have Verizon's GNexus? Your profile shows an AT&T carrier... otherwise you should probably update it.

I think the Kernel is what makes the difference. It seems to be the only difference i see between myself and the people like you have a reasonable battery life.
which one do you recommend? And i'm a noob at this so could you point me to a thread the explains how to flash it? If u cant its ok im sure i can figure it out.
I had the Thunderbolt with OEM extended battery, AOSP rom (TH3ORY roms), and imoseyon's lean kernel and used to get over 24-30 hours of battery life.
I've tried the 4.0.2, 4.0.3, and 4.0.4 with imoseyon and franco's kernels and still 7-8hrs is all I could hope for my Galaxy Nexus(stock battery). I've ordered the bigger battery with Costco but not here yet. Any suggestions other than the obvious: (please add to the list and I will update this original post)
1- Keep on AUTO brightness
2- avoid widgets
3- use a custom kernel (which one?)
I use francos with CM9. I always have everything switched on (Data, Sync, Wifi, GPS) and it only goes to about 50-40% after a days use and I consider myself a heavy user.
Edit:
As for using an extended battery, am I right in thinking that its only a 10-15% increase in capacity?

I have not had the extended battery yet, I will let you know when I get it. Do you change anything in Francos's kernel? I had a terrible experience. Isn't CM9 just a nightly release? Stable?
What radio are you using? I'm on the 4.04 radio
Hi guys, new here. I'm on the same boat as you on the battery, I'm running AOKP25 with Franco Kernel 18... I run a Hyperion 2000mAh battery and get about 8 hours with normal use , WiFi on, GPS off, Screen Brightnes on Auto, some whatsapp, emails, a couple of calls, a bit of browsing, and about an hour worth of reading in the kindle app... I know this should last longer... any ideas?
I can't post pic of the battery usage because I'm new but it basically is:
Screen: 57%
Android OS: 26%
Voice Calls: 4%
Phone Idle: 4%
Cell Standby: 3%
Browser: 2%
MediaServer: 2%
Android System: 2%
Thanks,

I'm on the latest European radio (cant remember the code).
No I don't change anything in francos, but you can if you want to boot it some more.
And yes CM9 is just a nightly but super-stable still in my experiences, definitely worth trying for a week or two.
I'm on a gsm nexus stock battery running codename with francos kernel. 18.4. I just had a super heavy day, 12 hours and I'm down to 13 percent. 3 hours screen time plus 3 hours playing music with poweramp while the screen was off. No wifi - 3g hspa all day. Kernel set to 700/1000 conservative. Running juice defender on aggressive. 1 push email and one email set for once every hour.
If you are not getting acceptable battery life after running a custom rom and kernel with juice defender (not even sure if it helps) then download cpu spy and see if you are making it to deep sleep. 99 percent of the time it is an app.

Thanks for the suggestions. I do also think there is something that is causing this. I do get a heated screen also at times. I am running the FA02 for both CDMA and LTE which is the latest radio. I did change to franco's kernel but may go back to CM's stock if I don't find anything.
Also, I'm on 4G 24/7. No 3G area where I live and work anymore (Chicago) which is great but I think it eats up battery. Will report my findings after cpu spy.
Used 10% in 1 hr and 30 minutes.
Most definitely suggest CPUSpy. Another option is BetterBatteryStats to find out what has your device in a partial wakelock. I had an issue with my Desire Z prior to moving to the Galaxy Nexus where a piece of software attempting to access the GPS would get stuck in the background, and cause a partial wakelock. Going from 20+ hours of usage down to ~11 was a bit of a downer, but BetterBatteryStats helped me find the problem.
My battery is pretty bad too. I'm running Apex (latest) and the lean kernel (latest).

I have frozen the maps app as well ( this was a major battery drain as it would constantly reopen) but it only gave me ~1 hour more.

Try running Codenamed Android and Franco Kernel.. I'm on my second day with this setup, and I'm really getting impressed. Running the stock battery. I have an extended one waiting to install once I've maxed out usage with the stocker.
Instead of starting a new thread I thought I would add to this one. My battery life just went from acceptable to abysmal and I also don't know why. I'm running latest Codename ROM with latest Franco kernel along with Gapps from 2/18. Kernel was installed after wiping cache/dalvik. I am lucky to get 12 hours without even touching the phone. Here are some screen grabs:
Please help me if you can!!
I'm no expert on radios but it looks like your signal sucks (all yellow) which can cause an insane drain on battery. Download cpuspy and make sure you are getting to deep sleep(your graph looks like you are watching a movie or 3) . My battery graph looks similar to yours when I use my phone constantly.

Sorry I didn't see that you have already downloaded cpu spy. My next thought would maybe it's just your connection. Try looking into flashing newer radios or disabling lte/4g, your area may just not be good for it.

I usually have good LTE coverage but I'll try tomorrow with it disabled. Also if I am using WiFi, will LTE still drain the battery?

Instead of starting a new thread I thought I would add to this one. My battery life just went from acceptable to abysmal and I also don't know why. I'm running latest Codename ROM with latest Franco kernel along with Gapps from 2/18. Kernel was installed after wiping cache/dalvik. I am lucky to get 12 hours without even touching the phone. Here are some screen grabs:

Maybe I'll try a new radio - I'm still on the original. Is there any other program besides Better Battery stats to find wakelocks?
Ran CM nightly with Franco's latest kernel and had some improvements but the battery on this thing is nothing compared to my extended Thunderbolt. I guess I was spoiled by that huge battery. How about CM's kernel? Anyoone has an opinion on that?
Having just the screen on will eat the battery at a 10-15% per hour. Using the phone, browsing XDA site, playing a game, using the Facebook app, or basically doing anything else eats the battery at even a higher rate. I don't understand when people say they are a heavy user and have 45% after 10 hours.Ccan't see that happening!!!
I'm using Juice Defender on aggresive, bought the BetterBattery Stat and nothing seem out of the ordinary, and CPUspy says that deep sleep is achieved when it is supposed to (over night 95% or more). I just think that this phone is a battery hog. I guess it's time to buy some spare batteries and an external charger. Any thoughts?

Heavy users do not get 10 hours of use with 45 percent left so don't believe people who say that.. At most that is moderate use.

I'm using AOKP b40 with the kernel that it comes with and I'm getting terrible battery life. I flashed Popcorn Kernel and Franco kernel once, but I had the problem where GTA III and other games would not start. I tried flashing the /bin/sdcard file but that borked the entire sdcard from mounting in Android so I had to reflash everything through adb.
I looked at Better Battery stats, and my phone is deep sleeping and nothing is wakelocking for longer than 5 minutes. I'm down to 67% after 15 minutes of screen on time and being unplugged for 2 hours. Is it just a bad kernel and should I try something else or is it my habits of using my phone? I'd like to get a lot more battery life out of this. I'm using the Verizon Galaxy Nexus with LTE turned off, GPS off, and Bluetooth off.
Thanks!
While my battery life is not as bad as yours, I too suffer from poor battery life. I can never squeeze any more than 2 hours of display on time at 45% brightness. I have tried AOKP and Slim ICS but they both give me mediocre battery life. I heard there was a franconkernel release which was by far one of the best released (r158?) I'm beginning to think I have a faulty battery as some people manage to get 4 hours of display time with descent standby.

Five minutes of keep awake is a lot for two hours.
I'm looking at Kernel Wakelock in BetterBatteryStats and it says PowerManagerService for 49 minutes. I'm at 54% now. I've been playing cached music for about an hour now with Google Play. Is there any more information I can give to see if I can rectify this problem?
Power manager is just charging. I would say that is a real issue though it shouldn't have dropped that quickly. What governor what frequencies and under volted?

I'm going to try with FrancoKernel and getting the sdcard file working properly tonight and see if it makes a difference. I leave it on overnight, it deep sleeps, but i still lose a good 15% battery. It's a bit ridiculous.

I don't turn data off, I keep 3G on. I have Facebook that syncs every 4 hours. My Google account syncs (not sure if there are intervals set elsewhere), and weather every 6 hours. Nothing else syncs to my knowledge.
EDIT: I didn't see your questions about my CPU settings. 1200MHz max, 350MHz min, interactive governor. I haven't touched voltages.
Okay if you can't live without sync your battery will always drain. Also change your governor to on demand or lazy if available. I usually just refresh everything manually and I get over 15 hours and 5 hours of display. Over wifi and maybe 2.5 of display over my terrible 3G speeds.

hol up, hol up....u mean to tell me I cant to use Facebook on this phone????? Im kind of mad I sold my Droid 3 to my mom....
After long being one of those people who would never post a thread with bias questions or answers.
It's come to this.
I long for the battery I had from ICS, I never got less than 4 hours screen on and 16 hours standby together.
The best I got was right at 5 hours screen on with 18 hours standby.
All with wifi/3G only, very little to none 4G, it's fine with me.
AOKP M6.
_____
Every single ROM/Kernel combination since I've moved to JB has provided me with just......crap......
AOKP, AOKP kangs, CM, Liquid, CNA, and Eclipse along in different combinations with
Faux, Lean, stock, 007, TinyKernel, and Trinity kernels.
It does not matter what combination I use.
I can barely get over 3 hours-ish screen on time with about 12-18 hours standby.
Now if I use the screen less than 2 hours, I can get up to two days standby, which is nice but not the overall complete usefulness I had.
I know battery has long been an issue for many of us, but I see people in threads talking about their 2 hours of screen on time like it's amazing when it's awful, especially when some of us, could, and used to get close to 5 with stock batteries or 2100 extended (mine)
If you're using LTE all the time, only 2 hours screen on is justified because it should be common knowledge what happens.
Point of the thread is this, I want to know, those on JB with stock or 2100mAh battery and can manage 4+ hours screen on and still close to a day of screen on, what's your secret? Every detail, spill them.
Is it our fault or are we just in a down time of battery efficiency in the ROMs and kernels?
There is no secret, jb is crap when compared to battery usage on ics

Couldn't figure out why my battery life was so poor the for the last month or so. Good to see I'm not the only one with the problem.
AOKP ICS with Franco kernel gave me amazing battery life. Jelly Bean not so much.
I personally believe that anyone getting more screen time than you (this goes for anyone) is:
a) Using their phone in an environment that is less bright than you (indoors, on the bus, in the subway)
b) and / or not syncing as many things as you / not as often as you.
Reverse the above for people getting less screen time than you.
This is the truth of the matter.
Personally, I get 2 to 3 hours to 3.5 hours of screen time on JB, depending on usage.
4 hours if I read in bed at night.
Edit: Kernel / ROM be damned, maybe it'll make 10 to 15 minutes worth of difference. NOBODY has presented scientific proof of any ROM/kernel being different from any other. It's always "oh yaa best battery life ever with this rom". It's just noise and cherry-picked screenshots.

I usually get at least 1 day worth of charge. My set up is pretty easy tho. Since I am in front of a computer 75% of the time , gmail sync is turned off, twitter is @ 4 hours, Facebook set to never with location turned off. Phone gps and location are also turned off unless I M walking towards the bus stop. I don't need to be checking my phone every 5 minutes so my useage is pretty stable and predictable. I wonder what you guys are doing to make the battery die so quick? If your usage patterns are pretty high with checking email 100s of texts and lots of twitter and Facebook well yeah I'll die quick.
Also I seem to get the same results with custom kernels and stock. I have little experience with CPU controls and and such so maybe setting a lower frequency will help?

Battery can be related to many causes leading to user error. I never used ICS on this phone so I honestly have no idea how great the battery was.
Google now, project butter and many other optimizations are to blame yes.
Depends how much you use it and what is going and the vary of networks going on and off and switching. I can normally pull off 3-4 hours of near heavy use. My droid incredible could only get at least 1 hour max. So maybe it is me but the nexus is a godsend for me.
Leaving the governor at interactive with low max and undervolting will help battery and a specific kernel. I can normally roll with 0-10% brightness and have all networks running and syncing.
I'm tired and ready to cook my tacos I'll be back later with more input.

Try this...
I have an old Android phone that my boy plays with...so I turn the cell radio off & have it on the wifi signal only. Even with him having the screen on for hours & hours (usually playing games), the phone will stay on battery for almost 4 days!
Turn your cell radio to airplane mode & then turn on wifi only...mess around with it, play games & see what the difference is. When I have a Sprint signal (usually junk 2g one) at home I get poor battery life...when I hack the PRL to choose a 3g (better) signal I get twice the battery life...
I've seen other battery life threads where the signal is a MAJOR factor & even with a strong 2g signal the 3g is probably better at not wasting battery. (4g is a whole other story)
I've found 4 things that almost double my battery life
1) Google Maps: huge battery drainer. freezing it doesn't help either, it has to be uninstalled. Mapquest from the play store is a decent battery friendly alternative. or if you really need gmaps, copy the .apk file and install it when needed, then uninstall afterward.
2) Push Email apps: i.e. Yahoo mail app, Gmail app... use the built-in email app and set the refresh limit to every hour.
3) 3G/2G: when your not using data, put it to 2g networks only. huge battery savings especially if you're somewhere with a weak 3/4g signal.
4) NFC/WIFI/GPS : turn them off if your not using them (obviously)
your results may vary, but doing these things did wonders for my battery. I average 23-26 hours with 2.5-3.5 hrs screen on time. before that I was getting 14-16 hrs with about 1.5-2 hrs screen on

Well, Switching 2g/3g is pretty battery draining, too. So better be sure you don't use 3g networks for a while. constantly switching just to be a minute or two at 2g just drains more
Turning of WiFi is pretty obvious but NFC and GPS shouldn't take any battery juice if they arn't in use... Someone tested it and could proove, that gps only uses battery power if it's searching for a connection.
As you can see, you basically need t neuter your device and constantly worry in order to get 'great' battery life, lol.

What is your brightness and do you have the wifi or LTE version?
On Wi-Fi with low brightness (25%) and no games I can get 8-9 hours screen time
If I play games... 6-7 hours
If you can't get more than 4-5 hours and you don't have LTE, your battery is probably defective

Before you go buying apps, find the root of the problem. Get BetterBatteryStats (must be rooted for kitkat) from the play store and see what is using your battery or keeping it from going to deep sleep.
Then look at ways to get even more battery life using apps like Greenify and others.

How many of those apps do you really need to constantly bug you when you're not using them anyway? I even greenify Facebook, basically because it's a memory hog.
I finally solved the problem, i flashed stock rom with factory images and installed elementalx kernel, needless to say now i am draining 3% for 30 min of on screen time and in the past it would have been over 10%
