links are just blocked at work, nvm.

Links working fine here...
That's probably what I'd get out of my NS if I used it fairly heavily... the display is a battery killer on that too. So about average, then.

Don't know what happened to the quality though,looked OK when I took them!
Hoping when this mobile data problem gets sorted battery life may increase as my phone was all over the place today!

Ouch, thats some serious drain. I was hoping for at least 18hrs. Still not a deal breaker for me.

Gosh, why is yours so much better than mine. Feeling like I have a dud here :/

3 hours damnm

Thats right around what I get on my charge on 3g only.

2H 55 of screen time looks to be pretty lacking if I'm not mistaken?
The Galaxy S II video run downs get like 8H or 4H on web browsing.
But yea, diff situations

Your pictures are broken can't see any of them.
Edit: 3h screen on sounds pretty normal to me. Depends though on the brightness of the screen.

Those are completely different. They start with a full battery and just play videos or browse the web for that amount of time. With this he was using for the phone for random things and still had the screen on for 3 hours.
On that note, how is it possible to have the screen on for 3 hours of a 12-hour day? You literally spent 1/4 of your day looking at the screen? Do you not have a job? My phone sits in a dock on my desk, but I probably use it around 15 minutes per day while at work, and then another 45 min or so after work (so total screen time, if it wasn't sitting in the dock, would be around 1 hour for an 18 hour day).

Those run down tests are from 100 to 0 doing 1 thing. This is throughout the day. The phone is still draining when the screen is off.

yea i understand.....but basically the screen time is how long the screen has been on throughout the day correct?
I had a galaxy S and it used to get like 4-5 hrs of screen time throughout a 12hr day. With the extended battery i could get about 6-7hrs of screen time.
Now on the iPhone 4, i get 2hrs of screen time with 80% battery left and had a standby of 6hrs. But yea....its iOS
Idk, 3hrs of screen time seems ehh to me. Im still probably gonna get the phone though, tired of iOS once again. Went from 3GS to Galaxy S to iPhone 4 and now possibly Galaxy Nexus....or wait for GS III

Wifi radio power on all day?

Several people who've had the phone for a few days have said the battery life gets better after a few charging cycles.

Calibrate the device, leave it off then charge it till it's full. Then use it till it is dead, then charge it again while switched off and keep doing that for the first week when you buy a device any device that uses a battery. I've always done this to my phone and my wife's sometimes friends too. After that the battery is calibrated, then if something goes wrong with the drain you would know, or if the battery life actually sucked Case 'n point EVO 4G.

yea, 3 hours used 56% of the 85% of the battery that was used. so really should be able to get 5 to 6 hours of just screen on time.

I uninstalled my virus protection yesterday and turned off sync and wifi whilst at work today about 11am and battery stats better today. Haven't been in a low signal area today so no problems or slowdowns caused by 2g/3g.
Taken off charge about 9.30am
Wondering if its the virus protection taken off or disabling sync and Wi-Fi or the fact I was in 3g area all day that's improved it.

Signal strength is usually the main problem I have...
Is there a native ability in ICS to disable WiFi scanning? ie - Leave WiFi on, but disable scanning for networks...

OP, I'll bet your batt life would be 3x better with something like Tasker managing your Wi-Fi connection.
IMO, BEST.ANDROID. APP. EVER.

Greatly improved battery life (CDMA)

Last night I restored my phone using the factory image. For some reason I anticipate an OTA soon so I wanted to be ready. Anyhow, before I suffered from the battery drain bug. I forgot to charge my phone last night, and didn't realize it until I got in my car and put it on the car charger and it said 89%. My first thought was that my battery drained over 10% in the hour I was getting ready and not using it! Then I went into battery settings and found out I never charged it.. then I found some pleasant... well, I'll just show you.

As you can see, I lost less than 5% battery during the 6+ hours my phone was unplugged. I had the phone in the living room charging while watching a movie. Then I unplugged and used it for about 20 minutes in the bedroom which accounts for the first rapid drop in battery. But after I set it down, the phone went into a coma. And I can't see exactly, but it looks like it was only 2 or 3% which is great!
Not sure what changed, I still have the same apps installed, even Facebook. I did, however, NOT disable VZ backup assistant like I normally do. Maybe that is what causes the OS to go bonkers? Thoughts?

I got about 20 hours out of mine yesterday (extended battery) with moderate usage (texting, ebay, facebook, web) This is after unlocking the bootloader and rooting. Unlocking the bootloader resets the phone to factory state. I've read a few other posts around the web where battery life is greatly improved after a factory reset. Android OS is still the main things devouring my battery, but I almost don't care with the performance I'm getting. I should also mention that I wiped battery stats from CWM and then calibrated the battery on first charge.
I'm no dev, so I don't know why a reset would help. Then again, maybe it was wiping battery stats and calibrating that helped me. Just my $.02

How did you calibrate the battery?

There's a free tool in the market that will calibrate for you. Have to be rooted though. Just search for calibrate.

Surprised this isn't getting more acknowledgement. Any one else experience the same after a reset?

Guess maybe I'm one of the lucky few...I've always had this type of battery life. The phone just sips power while the screen is off.
While it is on...well that's different. I keep the brightness high and get about 2-2.5 hours of screen time before it powers off.

The interesting thing here is that it seems that you have the Android OS constantly waking up the phone but yet it still barely uses battery.
Do you have location services turned on or off?

Turned on. I noticed that too but the overall awake time is low. Usually it would be over half of the entire time on battery, sometimes 100%.
Sent from my Galaxy Nexus using XDA App

I used 50% in about 3 hours on my extended battery.
fml.

Great battery life, but you didnt really use your phone much.
Your "Screen on" is only about 15% of those 6 hours. Which ends up being about an hour.
Still, none the less, great battery life/power consumption.

I think you missed the point. I said this was done while I was sleeping. Many people are experiencing extreme battery drain even when they aren't using the phone, as was I. After restoring from the factory image, my issue seems to be gone.

I unplugged my phone at 11:30 pm with 98%, woke up at 7:30 am today and it dropped to 76%. So a 20% drop in 8 hrs with the phone just sitting there with wi-fi on and no apps running. It'd be very interesting to see if a factory restore would help.
How's the battery life now that you're using it?

Im thinking of unlocking and rooting mine tonight. havent had a moment to read the walkthrough just yet.

i noticed this too last night/today. i went to sleep after installing bugless beast 4.0.3 cdma, left it off the charger, and today i saw the chart was pretty much a flat line. i don't recall the exact times, but i'll try to time it out. about 8 hours
i wonder if all the initial extreme battery drain reports are due to the 'wowanewphone' effect, where you are molesting your phone 24/7, as opposed to the typical day-to-day use you'll eventually fall back into

3% battery drain every 5 min. normal?

I know this is another battery topic, but specifically I am getting a drain of about 3% every 5 minutes while browsing the web on data. I am getting this drain at both 50% and 20% brightness. This drain seems high to me. I mean, during that 5 minutes, I am mostly just browsing one long page, so there is not much data activity going on in any case. Bluetooth, gps, and wifi are all off. I would like to hear other folks' experience.
Edit: my old hd2 with a small 1250 battery is running android and is only losing 1% every five minutes while doing the same thing!!

Possibly. Screen white or black factor. Type and speed of connection. Background processes. Battery temp. But that is a little higher.

Same for me. I'm not on LTE, I'm on 3g in Sweden. Just tried it myself and it drained 3% in 5 min of surfing with the stock browser.
And 2% more while writing this reply, that took 2 minutes.

I went out to do some Boxing Day shopping in the morning and used the phone quite a lot. Came back with 48% battery about 2 hours ago, haven't used the phone since and it still has 48% battery lol.

Your not supposed to use it, just keep it in your pocket.

Its probably down to bad battery calibration. This is a lot less to do with 'conditioning' the battery - which you don't need on Lithium based batteries - and more to do with Android understanding what level is 100%, 99%, 98% 50% and 0% etc.
Until you've been through a few real cycles from full to empty, the % is pretty inaccurate. Most people recharge at around 20 to 40% just because a charger is near by or its bed time, and that usually results in the levels being even more inaccurate at the higher end.
For example my battery will drop from 100% to 70% very quickly, the next 30% even slower and the last 40% seems to last forever :/
If you're rooted wipe your battery stats, do a full charge and let it drain to 0. The type of usage probably isn't that important, so play a game for 4 hours if you want . If you're not rooted, doing the same will still help make it more accurate, but of course previous usage will mess with those results.
---------- Post added at 04:05 PM ---------- Previous post was at 04:02 PM ----------
EDIT: In fact try this.. turn off the screen timeout temporarily, and leave it on the web page. Check the % every 5 minutes and keep a note of them. You should see that its not 3% over 5 minutes once you get past the first 10 to 20% of the battery.

Here is my overnight battery drain test. My phone was idle the whole time. Only on 2G mode and no wifi, no gps and no bluetooth.

Silly GSM users commenting on LTE device. tsk tsk... they just don't understand the immense power + battery drain of LTE.
LTE drains battery much much faster then GSM/3G. That's how it is on ALL LTE phones & the fact that the GN also has the biggest screen helps rape the battery. Sadly, what you are experiencing is normal for LTE. Im on my 2nd Nexus & calibrated both of the ones i had. Same exact issue as you and regardless of what apps/settings you adjust/disable, it's not going to help with battery much at all unless you turn off "mobile data"/LTE(or go into airplane mode).
When i have LTE on and am actually using the phone it seems like it's going through 1% battery every 1-2 minutes.... yet if i turn "mobile data" off it goes through 1% every 8 - 10 minutes instead. oh and all you weirdo "look how long my battery lasted NOT using my phone!" freaks... if i activate "airplane mode" & turn off the screen the battery will last 2 days. wee!!.. (why even have a phone lol)

I had both the LTE and GSM models. While both are terrible on battery, they lasted about the same. I did have the extended battery in the LTE, so I take that in consideration when saying they lasted about the same. No huge difference on the LTE.

I'm using an LTE Nexus with the official Sammy ext. Battery, yet my battery life is ****. After playing temple run for about 30min in total over a typical class day and tethering for 10min, my battery is down to less than half already. Is there something I'm doing wrong?

Well its not great either way, but the screen on and awake time in that screenshot looks more then half an hour. Looks at an estimate to be nearer an hour and a half which is a total screen on time of about 3 hours which is fair.

That's well over 30min of screen on time, and with a bad signal at the end that drains.
Doesn't seem super out of the ordinary, honestly.

In total I'd say my phone was playing Temple Run for 30-40 mins, and then frequent on-and-off with google talk and text messaging. I don't believe what its saying for the screen on is true, because it definitely looks to be on more than 50% of the time, but in reality I haven't used it more than 50%.
Are there apps that can be running in the background that's making my Nexus think that the screen is on?

No. The screen on time will be precisely (as much as it can be) displayed in that settings menu.

Why don't you put your phone down and pay attention in class?

Yup, your info shows lots of screen on time and hammering the processors with playing games.
And the LTE network takes a larger toll on the battery compared to GSM/HSPA.
The stock 1750mah hour battery is only good for maybe 5-6 hours of screen on gaming hammer time. With more modest normal voice/data usage the battery can go 24-48 hours.
USB chargers are easy to keep around. Bigger fatter 3300mah batteries are another option.

I have battery life that bad when I'm in the office, but I think it is because I have very light service...not enough service that it is totally usable, but just enough that the phone keeps trying to establish a connection...

Click on display in the battery usage to get your screen on time.
Expect 2-3 hours of screen on time with the LTE Nexus.

As others have said, check your screen on time. Just to clear something up the % listed next to the object in the battery menu tells you the percentage of the battery used, not the overall battery. For example, 50% used by Screen, and the battery level is at 30% means that the screen roughly used about 35% of the overall battery, not that the screen used 50% of the total battery.

iphone 4s dont have that kind of problem.

My maguro with the 2000 mah battery lasts all day with half a charge still left over with AOKP/Franco kernel, undervolted and hotplug mod.
I'm usually on wifi though, since I have wifi at both work and home. That definitely helps a lot.

Is this normal, an hour of web-browsing with screen on auto-brightness and phone drops from 100% to 71% ? Wifi was off, bluetooth on but not connected to anything. I have Better Battery Stats too, shall I post up? On stock ICS.

He said the wifi was off, please read people.

not sure if "insane" means bad or good. But it looks about average. The average screen on time ranges from 3.5 to 4.5 hours. Mine is dead center of that.
Bluetooth not connecting to anything still drains a lot because it is constantly scanning for other bluetooth devices.
BTW your reception is in the YEllow. that means that also leads to battery drain.
So if you have better reception and your bluetooth is off then your battery would last longer.
Note: I use bluetooth a lot and I find it to be one of the biggest factors for draining. more than GPS and Wifi. Although, using wifi with strong signal actually saves battery.

I really doubt that, because I did the same battery test Techradar* does, which is:
screen on full bright
Wifi on
Gmai, FB, etc all set to update as often as possible
Run a 1.5 hour long HD video full screen
At the end of that test I was at 84%. (the Video was on my SD card, not streaming)
In the video they have a graph of their stats for different phones using this test. GS2 and GS3 are top 2.

You're doubting that our phone doesn't last that... Uhh.. Short? I've had this phone since December and had many discussions with others on here about it and we agree that 4 hrs is about right.
So with that test you're saying that our phone can get over 6 hours throughout the say with normal use? Highly doubt it. You have to realize a couple things.
1. Wifi consumes less battery than 4g
2. You should factor in a normal days use that means including idle time i would say about 2% per hour maybe less.
3. Watching a movie means no "touch" interactions which means it consumes less battery than Web browsing or playing games.
So yes if you just leave the phone on the entire time without touching it. It'll last a long time. But with actually interacting with the phone and using 4g data. Most gets 4hr. Screen time in 17 hours of use ( you guys do get 7 hours of sleep right?)
I don't really believe that test. I know that the 4s battery sucks balls. Our phone lasts longer with our 4g on. It is saying that the one x is shorter?? One x and s lasts longer than our phone. So yeah.
