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.

New original battery + Full first time calibration = 4h15 of screen time

I just bought a new battery this weekend ( original 1750mah ) and i did a first time calibration ( charging for 10h without unplugging and drain it all until my phone closes by itself). Now i have a freaking awesome battery life with mid-heavy usage. 4h15 of screen time with 50% brightness, wifi on all the time, gps, auto-sync, franco kernel #11, XDA for few hours(white background), youtube, about 250 txt messages, 30 min of talk time. I just beat a new record submit your best screen on time.
**next step : 5h of screen time ( 30% brightness, no facebook app)

If you search here, someone made an experiment. He set to airplane mode and set the screen to display all pure black with lowest brightness. That resulted with about 10 hours 40 minutes.
So, that's max screen on time with standard battery.
Here my battery life with extended 2000mAh GSM battery
Granted, I don't sync and I set to brightness at 10%. But that's enough for me. Mostly I use my phone for web browsing, fb, g+, xda, games, etc. The stats below include Sygic GPS navigation for about 20 minutes.
At 61 hours stand by with 4 hours screen on time, I am very happy

I've gotten 5.25 hours as my record. Was strictly a wifi data run. I've also got 4.75 twice, HSPA data, but your 4.25 is probably more impressive if your background is that and the other stuff mixed in. All 1750 mah. Just got my 2000 mah yesterday.

I am getting about 5 hours of on screen time with my gsm Galaxy Nexus with the 2000mah extended battery from simshop,wifi on,100% brightness always & none of my settings are focused on saving battery life.Here is a screenshot of the wallpaper I usually use,sometimes I throw a lwp on.I also for testing purposes put Netflix on at 100% battery and streamed until the battery got to 5% and ended up getting 4 hours 23 minutes with the same settings as I wrote above.I am running 4.0.1 stock deodexed rom.Stock kernel.
Maybe this will finally be the thread where everyone actually shares the relevant information like Rom & Kernel,GSM/LTE,Extended or Stock battery, Screen Brightness,Sync on/off,Wifi/Data,Static or LWP.On screen time as opposed to just how long the phone has been in idle & even possibly the technique used to calibrate the battery.

Using redemption rom with stock kernel. Yeah I have wifi on the whole time I'm home. Which is usually from 4- til I plug in. I am on the extended battery. But I don't notice much of a boost from the normal battery with it. I also have gtalk signed in all day and use that almost constantly. Although today I haven't. My phone also always stays cool. It never gets warm.
Also I have everything on normal sync. Gmail,fb,twitter. And auto brightness.

If you're using 4G+wifi, aren't you really just using wifi? With wifi on, I can make it through the weekend easily with light to moderate use. 4G, not so much.

Have you managed to get over a day of battery life?

The phone is great but the battery really bothers me.
If I use my phone a bit it doesn't get me through the day. Sometimes i get as low as 8 hours of use with tops of 20 or so hours.
How do you manage it?

I use an Apex kernel and a 2000mah extended battery

Mines been great. Yesterday I was at 17+hrs which included over 3hrs of screen time and 1 hr of voice calls. I've only had my phone for less than a week, and have twice gotten over 4hrs of onscreen time (all with stock battery).
Running AOKP Milestone2 ROM with stock kernel.

I about a day and a half nearly 2 with stock and moderate use.
Batteries pretty damn good, you must have something installed that's eating it up. There's a good battery guide somewhere on these forums, usually helps track down the cause.

I usually get about 3 hours of screen time before I need to recharge. That should be normal.

AOKP + Franco kernel + 2000 mAh

Got two days of battery life just now (1 day 20 hours, to be exact). That's with 2h18m of screen time and 4h2m of voice calls. Screen time is mostly due to text messaging, Facebook, Foursquare, Twitter and Google Currents, so I guess... light to moderate usage?
WiFi is always on, Data is off, Sync is on (except for FB sync), location services off. Didn't sign out of Talk, but did sign out of Latitude.
Also, since I installed Facebook, when you run it for the first time, it downloads a lot of background data, regardless of sync settings. I let it do its thing while it's still charging, and it was all good after that.
Using AOKP b20, Franco 13.1, and stock battery.

36 hours is the most I've gotten out of the phone, but I did screenshot this not too long ago.

I would say the stock battery is borderline adequate. I find that on the stock system, if I use the screen for more than 3hrs, and have all my services sync'd, bluetooth, a few calls once in a while... I would have a hard time struggling to get to the end of the day without the phone giving me a battery warning.
How I've managed it is to get the samsung 2000mah extended battery. It's not a dramatic difference, but enough to make it noticable.
As well, I've kept the screen to about 40%, used a dark wall paper, loaded franco kernal and tweaked some of the settings to be more battery efficient.
Overall, I think it's acceptable right now. At least for how I use it.
I also find that my battery drains quite a bit where I work as the cell signal is on the borderline between no signal and 1-2 bars. That's why I keep a charger at work as well as in my car to give it some extra juice.

I find the battery is actually quite good.
I upgraded from a blackberry tour, and with similar moderate use the nexus actually gets me more battery use. However both phones being idle the blackberry lasted for days.
Overall i'm never away from a power source i can charge my phone, so as long as it lasts me roughly 1 day i'm good

Stock battery
Rom: aosp self-built from aosp master branch
Kernel: at the time, franco's nightly #8 or #11, can't remember exactly
Usage: light (3h screen on)
Went almost 3 days on one charge.

If you can't get days while idle with your GN, then something is definitely wrong.

Sent from my Galaxy Nexus using xda premium

I got my nexus 4 days ago.. Since then im harassing my phone.. Literally.. Im constantly installing application, customizing the homepages, making icons, widgets etc, surfing on web, exploring the market. 100% of time, Wifi or mobile data is in use (although i got unlimited data plan here (with speed of 4 mbits and 1 mbit upload), my wifi is more faster than mobile data.).
So i havent had a day with "normal" or "moderate" use on my GN.. And, battery lasts for over 24 hours.. And, autosync is always on, brightness is on 40% aprox, screen sleep 45 seconds (basicly its not sleeping cause im harassing it all the time )
Im all stock to the bone, just unlocked bootloader and rooted..
Im wondering what will happend when i start using my phone with moderate usage ..

Hmmm there are some interesting answers on this thread. The battery and the low sound have been the sole disappointments for me on the GN.
I get about 3.5 hours screen time before i have to recharge.
I guess if i turned everything off i could get better performance battery wise. But why would i spend almost $300 on a phone only to not use it? I am complete stock at the moment because i don't want to void the warranty but while i waiting for 4.0.3 i will be regularly using the hell out of my phone with a spare stock battery.

batteries have yet to perform at the level of the rest of the hardware, it's a fact. bear with it like the rest of us. of course we bought the phone to use it.
if you need battery life above all, turn off sync, it will do wonders.
personal pref: for more available resources, uninstall that widget crap, homescreens full of that i dont know whats the point of using them, even multiple homescreens, i rather have really important stuff on the launcher and just one homescren, black bg, no widgets. these are cpu and memory hogs, as well as 3rd party task killers, system monitors... keep it simple. less is more.

I assume no more than a day on my gn, but, as stupid as it sounds if you turn off the 3g and only enable 2g you improve your juice a lot. Most of the time we only need 2g.

[Q] How many hours do you get before you charge your HOX?

I did not see a thread similar to this for HOX. People have been saying that HOX battery is not as good as SG3 but I just wanted to get an idea how much other users are getting.
MY HOX White is giving me an awsome backup for 48 hours average with 2 hours screen time and 45 minutes talk time. I think it is awesome. Post your hours here.

Not to bad almost 3 days before I had to put it on the charger 5 hours screen time. Running Charmeleon v5.0.0 with stock kernel.

Hey man;
Sure the battery life in SGS3 is better, it has lighter processor (which doesn't help in heavy gaming, very fast in normal use though), more energy efficient AMOLED screen (which has less quality, but better brightness), and also the simpler TouchWiz UI (which is a bit childish in my opinion, but does the job well)
I get about 8 hours with heavy gaming (near 1 hours continuously) and web surfing (actually downloading, almost 500MB in total) and something like 1 hour watching music videos...

I get 2 1/2 - 3 hours screen time max! In the battery drain test my battery reaches 84% by the end of the hour, which I thought was great, but then again that test requires you to put your phone in Airplane Mode. The screen is a battery-hog imo, but its beautiful even with the stuck pixel I have haha.

LEt us get some more people to answer this one before we reach any conclusion.
Results are inconsistent for sure. Few people like me are getting 2 days average and few 2 hours!

For me it depends on what is running.
Normally I get about 14 hours of moderate use with 2-3 hours screen time.
Today I'm at 10hrs with 1.25hours screen time and I'm down to 11%. But I believe it is due to having wifi and viber running.
Personally it's my wifi that is really killing the battery. But given how I use it, it is perfectly acceptable

Is it true that non-rooted HOXs have poorer battery stats as compared to those that are rooted? If so, why?
I'm not rooted and am on stock everything.
How exactly do I go about testing the battery on my HOX?
Any tips for better battery for non-rooted devices?

I get about normal usage ( 3G-1 hour, Tegra games- half our, Music- 2 hour, SMS and Calls) 10h, just SMS and Calls about 30h.

The number of hours i get varies from time to time . On normal usage including listening to music, messaging, playing games and talking on the phone i get approx 4-5 hours max.

@Skywalker, I am all stock. How do I go about making the tweaks in the Rom?

Very frankly after receiving OTA 1.28 my battery lasts 2 days after every charge . some tips.
1. While you are listening to music keep the screen off as screen sucks up most of the charge.
2. I do not let my battery go below 15 %, I have read that letting them go below a particular level reduces the actual life.
3.Try these small steps, it resolved the issue of low battery life for me as I had read it somewhere:
> Turn Wifi and then 3G off
> Turn either Wifi or 3G on again
> Do not keep both "On" at the same time.
4. Kill the Maps process by going to the task manager ( If not using it all the time).

Just how TERRIBLE is the battery life ?

I wanted to get this phone as a replacement to my Nokia N8.
Having been loyal to Nokia over the years, I'm used to absolutely excellent battery life, where I get a good 2 days of normal use, or easily get through 1 day of heavy use.
Would the Galaxy Nexus be a really bad step down ?
Can anyone suggest their average battery life when having:
25% screen brightness,
GPS/BT/NFC/etc off until needed.
Sync only for WhatsApp
Messaging 1-2 hours a day
Music 2-3 hours a day
Browsing 1 hour a day

I get 8-9 hours standard usage

If only 3G, you'll probably pull about 12 hours and a little under 3 hours screen on.
-Brought to you by Marino's Galaxy Nexus-

Mine's on WiFi all the time with all the syncs and stuff. A few calls and messages + mild browsing. Normally I get 14-16h. Maximum was 24h with the wifi turned off I guess. Not the best results, but bearable.

I get about 4 hours screen on time, and a full day no problem.
Just charge when you go to bed at night and youll be good to go

I usually get one and a half days of standby time (average 37 hours as reported by GSAM Battery Monitor). So I usually only charge every other day. However, my screen use (1-2 hours) is much less than most people on this forum. If I use my phone heavily with screen on >2 hours, then it lasts just one day.
1-2 hours screen on time.
Brightness: 11% indoors, auto outdoors
GPS/BT always on
40 mins/day streaming Pandora music over HSPA+ and BT with screen off
Wifi + Airplane mode always on at home, with Wifi High Performance Widget
VoIP (Sipdroid) connected whenever on wifi

It's comparable to the selection from any OEM, though 4G and Jelly Bean's Project Butter are the top offenders (alongside display, that's more a given, though.)

These statements are invalid, people have reported great battery life with almost every combination out there. Secondly, OP you won't last more than.. Well could be 14 hours maybe 18, 14 especially assuming you use data to web browse. but it really depends on screen on time and, how spread out your usage is.
Sent from my Galaxy Nexus using xda premium

It will be a step down.
You will never get 2 days of battery life under any useful circumstances.
Unless you neuter your phone, as I've mentioned in another thread.

In all honesty, the gsm/cdma versions need to be compared totally different. I've had both and can say the gsm version can easily get 3 hrs of screen on time without even trying and the cdma version (toro) struggles to get 2hrs. So, when somebody replies about battery life, they really need to specify which version of the gnex they have or you could specifically ask for maguro/toro/toroplus users.
BTW, the screen on times I'm specifying are not on wifi and are using HSPA+ for the Maguro and LTE for the Toro.
On Maguro (GSM Version), I routinely get 2 days out of my gnex with light/normal use.

I have the GSM Galaxy Nexus and I keep my phone on Airplane Mode at home, work, & school (since all my calls & texts are made through google voice anyways) & data while I'm on the go. I mainly use Facebook, Google Voice, Groove IP, Instagram, Light Flow, Google Search (4.1), Google Maps, & music. Occasionally I game, watch movies, etc. Here's a typical day of use, 5 hours of screen time:

We don't have 3G where I live - but I have to charge my phone every night.
My usage is something like this: random surfing at work (read news and all), send quite a few texts (or Whatsapp messages), play music for almost 50 minutes straight... when I'm home, I'm left with 60 or 50%.
I do have a charger at the office though - but I don't always use it.
It depends on how strong your cell signal is; if you're in a spotty area, the battery drain will be higher. It also depends on the kernel you use (right now, I'm trying to find a decent kernel - not the stock one since I get random reboots on the stock kernel... my phone didn't have this problem before, oddly - even with Jelly bean on it... yeah, confusing... but I digress).
Anyway - it will last you a day easily. 3G? I think it'll last you a day there as well. It depends HOW you use your phone.

Thanks for all the replies. As a reply to one poster, yes I am getting the GSM version as there is no LTE really in the UK. But it seems my battery concerns are true looking at most of your answers. I'll have to be really really careful in order to get two days use out of it. Probably best to spend a bit more on another phone. Perhaps the GS2, but that doesn't seem to be much better..

If the battery lasts you one day, you shouldn't be so concerned about it. Not like you can't charge it during night... Also with a little optimization, it can easily last you a day. If you are still concerned about your battery, get an extra battery or an extended battery. Also I had SG2 before and the battery is better than Gnex, but not enough to get it over Gnex.
