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.
LTE EX Galaxy Nexus - AOSP KANG
Asus Transformer - 3.2.1 OC/UV
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!)
My phone essentially sits idle unless my screen is on...

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.

Yeah I just installed this today, giving it a trial run. It's OK so far.. I think just growing pains so far. Also, I don't think themes work just yet.. At least last I saw.

Ah okay.
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.

Are you talking about 3 hours MAX browsing or just being POWERED ON?
If you are talking about just being on for 3 hours, you are GROSSLY incorrect.

See my screen on time?
4 hours screen on time including 21 minutes using gps for Sygic Navigation is not bull****. Stand by for up to 61 hours, easy.
And I was using the phone extensively for web browsing, facebook, gplus, xda, games, etc.
All with stock rom and stock kernel, extended battery 2000mAh, gsm.

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.

Please reread what i wrote. MAX ON-SCREEN TIME.
it is not possible to go 4 hours of on-screen time with LTE enabled all day.

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.

I went 13 hours yesterday with LTE on all day and had almost 4 hours of screen on time. I'm running stock ICS unrooted and all of my sync stuff is enabled. I'm also using the extended battery.

would like proof. afaik, its impossible to get 4 hours of battery life with LTE enabled all day.
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 just flashed my GSM galaxy nexus to aokp build 22 and mated it with franco kernal 16.2. NOT using any extended battery.
im not sure if this is good or not. but 10 plus hours of battery and 3 and a half hours of screen time. near the end all the way to two percent i was tangoling with my girlfriend for an hour or so. CRAZY BATTERY LIFE ANYONE？
Sent from my Galaxy Nexus using xda premium
Yeah I am getting crazy good battery life too...Almost 22 hours off charger, 2 hours of screen time, and almost 50% of my battery remaining. This device is a beast, the battery is awesome.

Are you both using the same rom? Can this be the same with stock? My experience so far has been no where near that....unfortunately. Haha. Maybe I need to root and get this thing cranking!!!

No with stock I was getting much less.
I was running Gummy when that screen shot was taken. I have since moved to AOKP m3 but I don't find the battery as good so I am switching back to Gummy.
I consistently get atleast 15+ hours of battery with 4 hours of screen time on stock everything including battery. My brightness is around 25-30% percent though. I also keep my gps, bluetooth, auto sync off. Only use 2 widgets that refreshes automatically at a set time interval. Standby time is outstanding on this phone, it's just the screen that kills the battery. I can easily get through a week on standby.

I bet he also had an hour of screen on time..
I've searched the forums but found nothing. I'm using Codename Android with Lean kernel and it barely lasts 7 hours with moderate use. I turn 4G off whenever I'm not using it so I'm at a standstill.
Anyone having better experiences? What're YOU using..?

I got mine running AOKP Milestone 3 with Francos 16.1 running at 1350000-700000 with francoTurtle. I lose about 2.5%/hour with the screen off, and get about 5 hours screen time. Set to update weather every 4 hours and gmail pushes auto, and gtalk is signed out. I would say thats about normal for most people. O also running the 2100mhz battery. I can easily get through the day with a charge, although I prefer to plug it in whenever i get a chance.
I'm running AOKP build #23, Franco's kernel build #17.2 (just jumping from #16.2). And I'm using the original battery.
What I care is on screen time, I've got around 3h30 - 4h on screen time, depending on how I use my phone.
I am stuck deciding between this and the galaxy s3 for verizon. The biggest selling point to me is battery life. I want to be able to last a full day of texting, and tweeting then having to charge my phone when i get home. I don't want to have to carry two batteries around and the extended 3500mah+ batterys seem like overkill and make the phone huge. I guess my question is will i be able to use my phone for a day with the Verizon LTE version of the galaxy nexus. Sorry if this has been asked a million times.
It has been asked 10000 times, yes.
And the answer still remains the same.
Usage varies.
Look at your current phone.
Settings>battery>screen.
Screen on value of ~3 hours can be reached with the Toro.
If that's what you're getting...you can get that here too.

My current phone is a blackberry curve.....
But thanks for your answer, what ROM would you reccomend to get the best battery life?
There is no best rom. Every phone works differently in different environments... just download them all and try them!

You'll have to turn off LTE to do that. Same will be true of the SGSIII.

I am serious about to go back to GB. ICS is sucking in the category of battery life. I need to know what is going on.
I am running Re-Calk 0.1.17 with Agat 4.3 and CPU Sleeper. Took my phone off the charger at 8pm and already down to 85% with it being in nothing but deep sleep. Same thing basically happened on Blazer also.
I need something to keep me on ICS. Someone please tell me what you are using.
I have had the same issue. Ive tried many combinations of roms, kernels and tweaks but I still haven't been able to match calk's 3.0. Curious to see if anyone is getting decent battery life on ICS.
I'm getting good battery on aokp m6 but it also varies widely depending on what I do. if I play alot of games or watch alot of video I have about 10% after a 16-18hr day if I just browse and txt I go to bed between 30-50%. Only tweaks I did was disable the capacitive buttons and led by deleting their files from inside the he folder in /system
We are legion, for we are many.

i use system tuner pro and change the cpu setting power save plus all add all the tweaks
I dunno, whats good for you? I am back on my trusty CM9 Nightly 7/17 which has the FF18 repack kernel which was supposed to be worse on battery life than the FF11. I get 30 hours or so on my days off or days at work when i might check the phone a couple times an hour.
Heavy usage any rom, any android version can kill an E4GT in 3 or 4 hours most days i get 6 to 8 with an hour of 100% brightness screen on time.
I am on the sprint official OTA and I avg around 13 -18 hrs with 5-6 hours screen time....could be more if I wasn't a heavy usage type

2% screen on how many minutes was ur screen on
i think the reason why Calk 3.0 have superb battery life is because the CPU is underclocked at 800Mhz instead of 1.2Ghz
Just my $0.02
I was Super Galaxy ROM for a while and my battery life wasn't ever that great
I had to take my phone in for a signal problem (which ended up being a downed tower that the Sprint rep didn't bother to mention, don't get me started) and so I flashed to GB and then did the OTA update to ICS
I've been getting awesome battery life outta this thing now.. It was a really light use day today, but I'm at 60% after 13 hours (only 1 hr of screen on-time though).. but on SuperGalaxy I would usually be at about 20% of less even with little to no screen time.. (I did love everything else about Super Galaxy though)..
But I've seen lots of people say they got horrible battery life on the OTA... (I did start from a completely clean phone though if that matters)

no clue, i played a bit of temple run, made a few calls, and did a bit of texting
I'm running stock ICS and get the same battery life as GB. I can get 12-16 hours 8 if I'm on the phone constantly reading and browsing. Glad I don't have the issues others have had. At first my battery was pretty bad but it continued to improve over time.
