Take a look at this full detailed review, read the battery life report.

http://hemorrdroids.net/samsung-galaxy-nexus-review/

I think the battery is amazing.

And from tests here :

http://xdaforums.com/showthread.php?t=1366878&highlight=Max+brightness

You can get max 5 hours screen time with full brightness and all white.

While on min brightness all black, you will get 10 hours ... Screen time.

That will be less while you are doing something!
[Samsung Galaxy Nexus] case0:
At least Apple admitted a problem and fixed it..
[Samsung Galaxy Nexus] psycho2097:
+1 on that. I get 12 hrs out of my cappy,with 2-2.5 hrs n no cell signal 20%, inside the factory. But really, I was hoping to improve on that...hows the this compared to the gs2 or sensation?

[Samsung Galaxy Nexus] darkoroje:
3 hours of screen time is bad. Galaxy S II can do 4 hours, so saying that 3 hours is good doesn't sound right to me. Coming from a Galaxy S II I was expecting to get the same screen time but unfortunately that is not the case.

I think we are reaching the point where screens are getting to large for current battery technology.
[Samsung Galaxy Nexus] pukemon:
Yeah but the screen is bigger on nexus and op's usage is not light. More medium and leaning on heavy. I can get 7 hours straight on my atrix which is not typical use, my typical use allows 3-5 hours depending on my signal for the day and usually its not very good in downtown houston. On the weekend at my apt or my folks, typical usage allows me 4 hours plus easily on wifi and sometimes some gaming. I expect ~3 hours + to be typical for most users in a typical 12 hour rundown. Hopefull after some undervolting and tweaking that will be pushed to 4 hours and more.

[Samsung Galaxy Nexus] vapotrini:
Let's not forget that the GS2's battery life was pretty **** when it first came out. Hardly fair to compare a phone on mature software to a brand new phone on new software.
[Samsung Galaxy Nexus] darkoroje:
The problem is that the screen is #1 battery consumer, and no software can improve that.
[Samsung Galaxy Nexus] Annie the Eagle:
To be fair, battery life on Smartphones is never going to be fantastic. It just won't happen until some much improved battery technology comes out. People can "optimize" their ROMs or install Ultimate Juice Defender but lets face it, the actual reality is that the changes are minimal.

I'd say the graphics on some games (ShadowGun and Riptide GP) are close to PSP style graphics, what battery life does that have? 3 hours (maybe 4). And that hasn't got any things running in the background (Twitter, Facebook, Market Update Checks).

I can make it through a day of my usage just fine, which involves quite a lot of twittering and a bit of texting. I mainly use my phone as an internet browser as well and I can get through a day fine, I always carry my USB cable and powerplug with me, and while I understand that the whole point of a phone is to be mobile, I'm fine with that, just like someone carries a laptop charger with them when they take their laptop.

Comparing the iPhone 4S' battery life to the Galaxy Nexus' (or any Android Phone for that matter) is frankly a worthless comparison because they are COMPLETELY different. Android and iOS are totally different, and the processor on the iPhone 4S is underclocked to 0.8 GHz Dual Core anyway. Android does auto-sync alot, iOS relies heavily on Push (and therefore doesn't need to check every hour).
[Samsung Galaxy Nexus] Matcarroll:
Have you turned off active wallpaper? That saved me quite a lot. Also uninstalled my task killer and now battery is much better. Nothing like my iPhone 3gs, however this is so much better!
[Samsung Galaxy Nexus] Martinp86:
You do realise thats 25% of your waking day is spent with you looking at your phone.
[Samsung Galaxy Nexus] teleknEsis:
My previous phone was a G2x and I got my Galaxy Nexus on Monday. The battery life on the G2x was killing me. I'd regularly get ~6 hours, 8 if I was lucky. I couldn't even leave the phone unplugged overnight or it would die before I could wake up.

Cell Standby was mainly the culprit eating up ~50% of my battery, so needless to say I was very nervous about battery life of the Galaxy Nexus especially considering what I'd read so far.

My Galaxy Nexus had about 50% battery out of the box so I played with it for an hour or so and then charged it all the way to 100%.

Unplugged the first night at 6:30 pm and it didn't die until the next day at 11 pm!! I also had to turn on GPS, turn up screen brightness, and do everything possible to drain the battery by 11 so it could die and I could charge it overnight.

This was also with many sessions with the camera, video camera (my kids played with the real-time face altering effects for at least 30 minutes), web browsing, lots of email, texting, google talk, maps, twitter, etc. I did not take it lightly on the phone the first day.

After charging overnight, I unplugged at 6:30 am yesterday morning and as of right now (9 am) I still have 29% battery left.

I think it goes without saying I'm completely blown away by the stellar battery life. I was hopeful because I know several people with the Galaxy S II on multiple carriers and they all get outstanding battery life. Very, very happy with my purchase.
[Samsung Galaxy Nexus] oilfighter:
That's incredible. Would you mind posting some screen shots of the battery usage? I have a g2x right now, so your experience is very relevant to me.
[Samsung Galaxy Nexus] teleknEsis:
Here ya go. Still at 24% now after almost 29 hours.
[Samsung Galaxy Nexus] cenwesi:
woooahh...i am speechless.
[Samsung Galaxy Nexus] richmelchr:
wow, your screen % is so low. do you just keep it at 0% like me or is it on auto and you haven't been using the phone at all?
[Samsung Galaxy Nexus] teleknEsis:
Screen brightness is set to about 1/3 of the way up the slider, no auto-brightness, and I've been using it pretty heavily, but I haven't really played any games (other than maybe 20 minutes of Fruit Ninja).

Like I said before, I've been absolutely blown away by battery life given my heartache with the G2x.

http://www.androidcentral.com/samsung-galaxy-nexus-battery-life-some-updated-impressions

Here's a post from androidcentral from their reviewer that has the Galaxy Nexus. Just a follow up on his experiences with the battery life after a week or so. Seems pretty promising to me anyways.
[Samsung Galaxy Nexus] leyvatron:
What is your display usage time?
[Samsung Galaxy Nexus] farrock02:
That looks pretty good cause im getting about 10hour less battery life that i getting with ny at&t gs2. So from 20 to 10 hours. Also the pic that you posted shows that you charged it a little within that timeline. That meter only resets when you hit 100%
[Samsung Galaxy Nexus] jhericurls:
Goes to show, not all GN are equal. I'm lucky to get 12 hours.
[Samsung Galaxy Nexus] rye&ginger:
OP you are a heavy user, not a light user.

Invest in aftermarket batteries and wall charger for them. I have 2 for my SGS and it makes it simple.
[Samsung Galaxy Nexus] teleknEsis:
Right now display usage time is 1 hr 59 min and I now have 4% battery left.

---------- Post added at 10:58 PM ---------- Previous post was at 10:56 PM ----------

Actually what happened on that power spike was that my phone froze and I had to pull the battery. When it started back up it was over 10% lower than when I pulled the battery. I plugged the phone into the computer to run logcat when it rebooted to see what was going on, and while it was plugged in for less than 30 seconds it jumped the 10% battery that i lost when I pulled the battery.
[Samsung Galaxy Nexus] denero1:
OP your not a heavy user android phones don't allow for heavy usage when I got my first android I thought it was a faulty battery it drained so quick come to find out it's the norm what is happening is users and their love for a product overshadows their rational thinking so before they accept truth they will bash you and tell you what your doing wrong

i also love android products but we have to accept right now the tech for batteries isn't there so it will result in sucky battery life for smartphones period
[Samsung Galaxy Nexus] lokhor:
I have a 2000mah battery in my SGSII and I am lucky to get 3.5hrs screen time, so far with the Galaxy Nexus I have reached 15hrs with 3hrs screen time before it died and that was on the second battery cycle. Pretty much all the same apps and stuff syncing as well.
[Samsung Galaxy Nexus] McCadi:
FAAKE! Lol jk but seriously how did u do it? Look at a clip of mine after 4 days:

He said he played the game days ago, and it's still showing up days later. Geez..
[Samsung Galaxy Nexus] republitarian:
OP: try using black.PNG background. Doubled my battery life after switching to black background.
[Samsung Galaxy Nexus] :
This is what I got from moderate to heavy use. Playing games, browsing web, lots of chat and about 20 min of phone call.

Here are some pics with my battery life with moderate to heavy use.
[Samsung Galaxy Nexus] jhericurls:
I had very bad battery life < 12 hrs and read all the threads and didn't find any useful information.

So after a few tweaks I'm 10 hours in and still 45%... how? Read on

- Install Green Power to monitor mobile data.

- Settings > development options > limit background process to 3.

Also I disable a number of apps:

- NFC services

- Setup wizard

- Talkback

- Talk

- Google Bookmark sync

- DRM protected content
[Samsung Galaxy Nexus] joshnichols189:
Are you retarded? 25% of his day he spent on his phone and he's not a heavy user? I think YOUR rational thinking is being overshadowed by your perception that our rational thinking is being overshadowed.
[Samsung Galaxy Nexus] wrayrb:
In other forums, members have noted that conditioning the battery before first use significantly improved battery life. Have you tried that?

BTW, conditioning means fully charging it out of the box, fully discharging it, and repeating this cycle 3 times. I am not sure how you "fully discharge" it, other that to play a video repeatedly til it dies.

If anyone has tried that, let us know if it helps.
[Samsung Galaxy Nexus] rashad1:
I think certain apps suck up juice. Facebook was constantly syncing since there was no way to stop until, I cut off it's background data and I'm noticing better battery life. It could be because the battery life is improving as I break in the battery. I have yet to see it last more than 8 hours though
[Samsung Galaxy Nexus] sjauquet:
It looks like you do a lot off little usb charges isnt'it ?

with the resolution fo the screenshot it's not well visible.

Am I wrong ?
[Samsung Galaxy Nexus] Danny80y:
Heavy or light use gives me an easy 12hours......What more do you want? :D What did you guys expect... did you want this phone to run 5 days without charging? :confused::confused::D Also, this isn't IOS so YOU MUST manage how many apps are running and working when you have the screen off......
[Samsung Galaxy Nexus] teleknEsis:
Wrong. As I said before, it was plugged into USB for under 60 seconds after I pulled the battery when it froze so I could check logcat. Other than that it didn't touch a USB cable or charger the entire time. Ended up getting 33+ hours before the phone finally died yesterday.
[Samsung Galaxy Nexus] TroyBoy30:
yes! :p

ios does a great job of managing apps on its own! guess ill have to learn to kill stuff?
[Samsung Galaxy Nexus] Danny80y:
Not really kill them but if stuff is set to run when your phone should be sleeping you will notice less battery life. If you want a more IOS feel use something like juice defender.... but if you set your apps right and watch what apps are doing after your screen is off its pretty easy to spot battery hogs (unlike IOS where you have no idea what apps are using battery and they get randomly shut down) Here is mine running lightflow as well as my normal use.
[Samsung Galaxy Nexus] paOol:
ok guys, so we've seen evidence of the OP claiming poor battery life.

and we've seen evidence of telekenesis showing great battery life.

here is something to consider, how you charge the phone can impact the battery life.

what does this mean? If you have an A/C adapter and charge your phone from dead, you will notice that it gets recharged quickly and the battery life is also not that great.

If you charge via USB (connected to a computer), it takes longer to recharge but the battery life is also longer. It has to do with the amperages while charging, but I don't remember the numbers off the top of my head and don't want to give inaccurate info.

EDIT:

I suspect that the OP charges his via a/c adapter, thus the shorter battery life. It may also be some background services that are draining the battery as well.
[Samsung Galaxy Nexus] Luxferro:
I just got my phone a little over 4 hours ago. Played with it for 20 minutes, then charged it to full with the wall charger it came with. Right now it has 73% left. about 3 hours since fully charged, and 1 hour 7 mins of screen on usage.

To me, that seems fine, as I know after the battery gets a few charge/discharge cycles it will improve just like every time you flash a new rom. Takes a bit to build up battery stats.

I forgot to mention that all that time I been at work where I get no cell reception.
[Samsung Galaxy Nexus] Super Chimp:
I have only just got my Nexus and the battery life seems about average for an Android device considering how big its screen along with the high resolution nature of it. But I will keep a close eye on it.
[Samsung Galaxy Nexus] aindow:
Here's my latest results
[Samsung Galaxy Nexus] dnlsmy:
Nice Text.;)
[Samsung Galaxy Nexus] kam187:
LOL, i love how finishing taking screen shots was more important than reading and replying :P
[Samsung Galaxy Nexus] freshlycutlawn:
OP is right, that is terrible battery life, on my GS II I can get at least 12 hours before I stop counting and could easily go a whole day if need be, on the stock rom with WiFi running all day as well as browsing and social networking plus music, a good 30 mins to an hour of each and a couple of hours of music. This is a 4.3" display but consider how much of the GN screen is black, the buttons are combined in so the screen is not really that much larger in comparison in terms of useable space. Today I'm running 12 hours strong, its about 6:40 and I plan to get easily enough battery until about 12-1 am. Not to mention I heavily text all day (over 500). I agree with OP there is a problem. I'm not trying to flame anyone, just hope this helps.
[Samsung Galaxy Nexus] Matcarroll:
I just played a game for the first time since getting the phone 2 weeks ago. Tetris used 12% of my battery which is now only at 11% and I only used the game for 15 minutes! I roughly calculate this to be about 2h30m on full battery if gaming alone which is not very good at all!
[Samsung Galaxy Nexus] martonikaj:
Not really. You kill more battery managing tasks than letting them run lol.
[Samsung Galaxy Nexus] pukemon:
Awwwwww.

Sent from my samsung gt i9250 which is in the wrong state.
[Samsung Galaxy Nexus] Danny80y:
But if you want them running..... most are better managed than not.....yes.. I think we all know if you don't run any apps you use less battery....:p
[Samsung Galaxy Nexus] syntrix:
No, it has to do with amperage available, not voltage. Voltage is a constant.

Most usb connections are less than .5 amps.

Most wired chargers are around 1.0 amps.

Please don't spread inaccurate information.
[Samsung Galaxy Nexus] kam187:
After a pretty mediocre first day of about 13 hours, I set the screen to auto dim using the power widget, and when i did some light browsing i set it to half dim. I also set background process limit to 3 in settings -> development.

I have 5 email addresses on auto sync, facebook (although only used it for 10 mins in the morning), and twitter (didn't use it today).

I had a long phone call this morning, but mostly sms for the rest of the day. So far so good. Although today is definitely not a usual usage day for me its still an interesting experiment.

Edit: sorry forgot the screen time one, Its 1 hour 7 mins 25 seconds.
[Samsung Galaxy Nexus] Spybreak:
My first day with my GNexus has netted me:

12 hours on battery

3 hours 45 minutes display time.

I've been on wifi almost all day and being the first day I've played with the device quite a lot. Not bad so far for the first full charge.
[Samsung Galaxy Nexus] Tjotte:
Turn off unneccessary (or how you spell it) updates, for example, set FB to update every 4h or never, it will still update on opening app, weather widget to every 4-6h(or look at the sky) etc, etc...
[Samsung Galaxy Nexus] helen_xxxx:
Quite happy with my battery life.
[Samsung Galaxy Nexus] kam187:
You can't access the facebook menu yet :/ They really need to update that app!
[Samsung Galaxy Nexus] paOol:
edited my original post. the point is unchanged, I just got the jargon mixed up.
[Samsung Galaxy Nexus] McCadi:
So I just ran a screen on test from fully charged to 1% at lowest brightness while browsing web articles and texting. 2:04 hours. This phone would suck balls for gaming.
[Samsung Galaxy Nexus] kam187:
what?!? Not that I don't believe you, i have to see this for myself :/
[Samsung Galaxy Nexus] paOol:
are you charging via your computer/laptop?

or a/c adapter?
[Samsung Galaxy Nexus] McCadi:
a/c. I should try using USB to conputer tonight to see if that changes anything.
[Samsung Galaxy Nexus] Luxferro:
Something is off with your results. Here is my phone on it's first charge out of the box today. Played with it for 20 mins. Used wall charger that came with it to charge to 100%. Went to work. And I have crappy cell service in the building at work.

There are 2 gaps in my graph. One was from a reboot, and the 2nd one was when I was playing in fastboot and the stock recovery trying to see if I can force it to update manually... but no write access to /cache/ which is where the phone downloads it too when it gets it.
[Samsung Galaxy Nexus] McCadi:
interesting. What setting are you using? Here is a screen shot from my test at 22%. Oh the call in there was 20 minutes fyi.
[Samsung Galaxy Nexus] Luxferro:
I keep my screen on min brightness from the power toggle widget thingy. Only setting really.

Just how I always use my phone (coming from nexus s). I haven't signed into google +, so there is no instant uploads, or data syncing from it. No facebook app, so no syncing there. I tested navigator on the way to work. Used google voice texting all day, XDA app all day. I played with browser some, redid my chrome sync so all my bookmarks are on the phone. Played a HD video from youtube to see how the screen looked... did that a few times. Played one level of a puzzle games. Updated and installed a hand full of apps from the market.
[Samsung Galaxy Nexus] Arcadia310:
I figured out that my Exchange e-mail account was set to Push for the syncing. I'm no expert but I think that means instantaneous syncing right? I disabled that and put it at 30 minute intervals and that alone increased my battery life a good amount. I'm still not seeing the 15+ hours with 30% left that others are seeing though. I average around 2 1/2 hours of screen time daily and around 12 hours I'm pretty low. I try to shy away from heavy web browsing, YouTube, or games because I know those will rape battery life. Really wish I could do whatever I want and not have to worry about it but oh well.

The main culprit here is the screen and no matter what I'm doing the battery drains as long as the screen is on. When its off it can last a pretty good time.
[Samsung Galaxy Nexus] basizeland:
I noticed something weird with my battery life I had to pull the battery out and put it back in, I then check my battery stats a little while later to find that it dropped a heap when i pulled the battery out and put it back in.
[Samsung Galaxy Nexus] voxigenboy:
heh... on my Thunderbolt w/ stock battery & under constant use w/ 4G on, it lasted about 1 1/2 - 2 hours before it got to 0% and shut down. on my Rezound it lasts about 1/2 hour longer. seems Dec. 9th will be the day for us Verizon folk & i just know i'm going to have a similiar battery experience with the Nexus.

i guess you could say i'm a "heavy user" as i'll have the phone multi-tasking(downloading a torrent, streaming music/video, browsing the web & IM'ng at the same time). then again, i am also on an extended 4G network(not a true 4G) so because of that the radio works overtime and my phones get hot easy... thus also causes the battery to drain quicker.

i just hope Mugen or Seidio release some gigantic extended battery for it similiar to the 4500mAh for the thunderbolt.
[Samsung Galaxy Nexus] Clyzm:
That's been the pitfall of many Android phones this generation. A 4.65" screen just uses a ton of power. There's no way around it.

I haven't had a phone last me two days properly since my Xperia Play, and that's only because the screen is utter garbage on that phone.
[Samsung Galaxy Nexus] Luxferro:
@basizeland,

you sure your phone didn't lock up and it was draining battery while locked? That would account for lose of time in your graph. If the phone was working fine before you pulled the batter, and it dropped that much, then something is wrong.

I'm gonna go with it locking up, or partially locking up and the battery stats froze at some point.
[Samsung Galaxy Nexus] basizeland:
Yeah it did lock up but I pulled the battery out basically straight away so I wouldn't think it could drain the battery that fast :confused:
[Samsung Galaxy Nexus] aindow:
Well spotted. Lol.
[Samsung Galaxy Nexus] addicted2phones:
Guys just wait for a bigger battery from Samsung like they did with the galaxy s2. I'm using the galaxy note and the battery life is very good. All the nexus needs is the same 2500ma battery like the note and everyone will be happy.

[Samsung Galaxy Nexus] pukemon:
lmao. the note battery might fit a little funny in the nexus. there is hope that the 2000mah battery for the nexus in korea might work and be able to purchased.
[Samsung Galaxy Nexus] nizmoz:
I wish. I returned after 3 weeks my Skyrocket due to Battery life because I need a phone that will last me a full day. I had to charge that phone mid day to make it. Sometimes 3 times. My iPhone 4 only drops 20% from the same usage. And I am in IT and this was my 2nd android phone. Loved the o/s but battery life ruined it for me.
[Samsung Galaxy Nexus] Super Chimp:
The battery life of the Nexus seems very much par for course for Android handsets of the class, though I would say the Note has a better battery life, but then that's a rather different device and not strictly comparable.
[Samsung Galaxy Nexus] nyijedi:
How did you cut off background data for facebook? I want to keep facebook installed, but since we can't access the menu in the app yet, I'm not sure whether it's syncing all the time.
[Samsung Galaxy Nexus] king23adrianc:
actually, i dont change anything with my nexus s before, i kept it syncing 1 hr and push notification if that is the default?? i just kept that and my battery was pretty good in nexus s

now with galaxy nexus, no menu key cuz using stock rom now, screen off idle, i get probably 1% drain with wifi on per hour with default setting of facebook. so i dont see it draining that much battery.

The phone is also very thin, so I wouldn't mind putting on a new back cover with an extended battery.

The stock back cover is flimsy plastic anyway.
