The battery life is Godly on the Galaxy Nexus (Mine's a GSM model...I have no clue about the CDMA version)
With around 10 calls made, my brightness using the power control widget at "half" (I think its something like 40%), wifi on all day, data on, bluetooth&GPS off, NFC off, and almost 2 hours of onscreen time spent texting, surfing the web and gaming I got almost 22 hours on battery with 46% remaining! Pics for proof:

For those interested in getting this type of performance, I have sync OFF and manually sync whenever I want to check something (mail, weather widget, etc)
I have not had a phone with this great of battery since the Xperia Ray. This is unbelieveable though.
Also for those interested this is what I am running for ROM:
Android version: 4.0.3
Kernel Version: 3.0.18-imoseyon-1.9.0-04417-gcef4285 [email protected] #408
Build number: Gummy-MAGURO v0.7.6
Now how should I kill off my remaining 46%? Because web browsing, playing Nintendo 64 games, Facebook, are not cutting it! LMAO
100% WiFi use and no auto-sync or background data on, that's not surprising whatsoever.

On another note, could you tell me if games are able to push background data with auto sync off? I've always wondered that.
For what it's worth, Samsung said this phone should have a six day standby time and twelve hour usage time...
Maybe turning all the features of the phone off will help, but then why have a phone like this if you limit it so much?

Its not really limiting it though.
If I want to see the weather, I touch the widget to sync. If I want to see if I got any mail, I go into the app and it will sync...I get my data when I choose to.
I don't own anything to hook up via blue tooth, and I will just turn GPS on when I check google maps, takes an extra 3 seconds.
I am not missing out on anything, I am literally getting 2 days between charges. But I charge every night anyways, so I can basically surf the web or do whatever on the device all day and still have a ton of juice at the end of the day.
hey man, if thats how u use your phone, then u have great battery life! everyone's uses are different! people can say "oh your bluetooth isnt on" but not everyone uses bluetooth, or needs their auto sync on, etc! some people like to check these things manually
you should update your kernel to 1.10, reports have said that it brings back battery of 1.7.4 but also ups the overall speed/smoothness of the phone

Yeah I mostly just call, text, websurf, and game. So it works for me.
In comparison, using my Xperia x10, Samsung Captivate, Desire Z, Desire S, Xperia Arc, Nexus S, and Xperia Ray I never got battery life like this. The Ray was close, but this is even better...considering the size of the screen this is really great in my opinion.
I just love this device so much, I am thinking I will just always stick to the Nexus line of devices for now on.

I think I am just impressed with this so much because next to what I was running at stock (4.0.1) this blows it away.
Having the screen on for ~2hours is not a clear representation of it's battery life.

Look, Samsung has NO way to give standby times when everyone uses their phone differently. I sync differently from you. This phone WILL get six days standby. My old Vibrant is rated at 16 days standby, and you know, it just about will get that. "Standby" times aren't "my screen is off". Standby times are no data/wifi/sync and my screen is off. My mother has my unlocked Vibrant on AT&T. She doesn't have a data plan. Data/Sync is off. It's used as a PHONE. After her normal use, which is about 10 minutes of talking a day, it'll be at around 40% after 6 days. At that point, she usually charges it... and that's with evil, battery draining TouchWiz! There is no way for a manufacturer to adequately predict standby times with a device connected to a data network.
Honestly, for the life of me I can't figure out why this is an amazingly hard concept for people to grasp. Just because it's a "smart phone" doesn't mean that manufacturer's test battery life with data/wifi on. Probably because unlike the majority of people in every random battery thread on the internet, manufacturer's realize that once a data network comes into play, usage/sync WILL be different. Even power consumption can vary from tower to tower.

then I destroy that as its unlimited data plan inc tether is my broadband at home.

Perhaps you're giving Samsung too much credit. Apple lists the details of their battery tests on their site, and when they say "10 hours of use", it's not piddling around with sync off, location off, etc. it's actual use (calls, web browsing, video, music).
Look at gsmarenas battery tests http://blog.gsmarena.com/samsung-galaxy-nexus-battery-life-fully-tested-results-come-out-disappointing-test/.. Galaxy Nexus is tied for second worst and all phones were tested the same way. Maybe "real world" use will affect a single device from day to day, but when a phone is compared to close to twenty other phones under the same conditions, it makes you realize how poor the battery life is. Maybe 4.0.5 will make things better... I hope so.
Sorry for a newbie question.
I've had Auto Sync ON all day and I wonder what Auto Sync does exactly ?
Can someone light my day ? Thanks

So I've had my Defy a week and I like it, more than I thought I would to be honest.
However, one thing that's bugging me is the battery life.
In their review, Engadget actually highlighted the battery life as one of the big plus-points of the Defy.
They state:
Engadget said:
In our experience, the Defy seems to have stellar battery life, which is relatively hard to come by among Android phones. Not only we were able to consistently make it comfortably through an entire day on a charge, but we were surprised to find that after putting the phone away with about 75 percent charge, it was still on with 21 percent remaining two days later. Granted, it spent most of that time in WiFi calling range (which disables the cellular radio), but many smartphones give up the ghost from 100 percent charge in less time...
Click to expand...

Now, I'm not using wi-fi calling but I don't think that should excuse or explain the fact that my phone barely lasts a day when at least one other handset has such significantly better battery life.
Anyway, I was just wondering how everyone else's Defys were performing.
Im coming from a vibrant and the battery on this is the best on android so far that i've ever used(g1, mytouch, mytouch 4, vibrant, etc.

If you don't mind me asking though, how long do you go between charges?
As I said, I'm lucky if I make it much more than a day - certainly two days isn't possible.
But I'm not a particularly heavy user, a bit of internet and a few texts here and there but very little in the way of calls, so I kind of feel like I should be getting more out of the handset.
When I check the battery usage, it's quite often ~40% each for 'Mobile Standby' and 'Phone Idle'.
So the vast majority of the drain is just from the phone being on, not from anything I'm actively doing.
Is this your first smartphone? =)
I go a day and a half or so. I'm heavy on web use and playing 'slice it' all day.
for my usage, im THRILLED to have a phone that can still have 30-40% at the end of a long day.

Just try to reboot the phone after fully charged and detached from power. There is an issue with the "suspend" process in some cases (not only on Froyo 2.2) which disappears after rebooting. Mine lasts 2-3 days with average use.
The issue at Google (I am not allowed to post links as a new user )
code.google.com/p/android/issues/detail?id=11126
I can use the web steady for 5 hours, this includes some streaming video, if I start at 100% its down to 10% by then. At work it lasts easily all day but it gets little web usage and maybe an hour of talking. I use battery booster and advanced task killer, my backlight is set at 70%.
With moderate use (some calls, lots of texts, some web browsing) I get 2 days. It needs to be charged at the end of day 2, but I'm happy with it. I don't have any ot the social networking crap on so it's not constantly syncing. I think that may have something to do with it. I keep my backlight way down too.
Battery life? i got defy just a week ago and first impressions are good. You know, in the first days you make yuor phone working a lot, testing all the features, trying new apps from the market (so internet connection always on) , watching some movies, playing 3d games!
So a really heavy use, but power lasts at least 1,5 days. So i think using the phone moderately makes the battery life easily up to 3 days.
Try some task-killer app, and then test the power duration. Some softwares stay in background and keep draining power.

No.
And I don't see what that's got to do with anything.
My battery life seems to be noticeably poorer than what the majority of people here are quoting.
If I were to use the web for 5 hours, there's no way I'd have anywhere near 30-40% of my battery left.

Having looked at your link, it sounds as though when that's happening, people can see the Suspend process listed in the break-down of what's using the battery.
I've never seen it listed, so I'm not sure that's the problem here.

I've got Spare Parts installed and it's set to 'aggressively' monitor and kill processes.
A friend recommended it over the likes of Advanced Task Killer because it's supposed to be better at differentiating between apps that are safe to kill and parts of the core software/system that could cause issues if closed.
I get what you're saying about using the phone more than normal because it's new but in the 8 days since I got it, I've spent 7 at work, so I haven't had that much scope to mess around with it.
I've switched the screen from automatic brightness control and I've disabled the background syncing for facebook, so hopefully that'll make a difference.
If not, since it's just over a week, I'm well inside the 28 days I can have it swapped for being faulty.
Quadrant: 1100 points, Linpack: 6,49 Mflops
Edit: ooops, should read the title more carefully next time.
My defy runs for about 40 hours on one battery charge.
i have to charge mine everyday at night after using it whole day, time to time. Not bad tbh.
A task killer is NOT necessary.
It seems like blur services are push rather than pull which uses much less battery (think blackberry). But im not 100%.
I've set up yahoo, corporate, facebook, and picasa just to test it out and it didn't make much difference in my battery life.
I consistently get a day and a half (unless i play games). Can push to 2 days if i put on airplane mode overnight.

Found this on a german forum, as you can see, he was not in flight mode. I guess my desire's battery won't last that long.
I can go about one full day with moderate/somewhat heavy usage. Won't last 2 full days though.

People keep saying that but I'm not convinced.
I mean, if I use my browser say and then finish using it and know I won't need it again for a while, why prevent me from actually closing/killing it?
It seems so ridiculously counter-intuitive.
Plus, if it's really not necessary, then why are so many of them being developed?
Even Samsung are producing task managers now for devices like the Galaxy Tab - if it really wasn't necessary, surely one of Google's top hardware partners would know that.
And samsung is so great at making stuff...? Touchwiz??
Also, samsung's task killer does not show inactive or background apps like most task killers do.
What is the harm in the browser being open? It uses no cpu+ this phone has more than enough ram that it doesn't need you to close apps to keep things running smoothly.
It also will not improve your battery if you arbitrarily close an app only to re-open it later and use more processes.
Just my 2 cents on this topic.

Something i already posted in a german forum about my battery life:
2,5h gaming (Zenonia),
3h mobile internet (ICQ, Yahoo-mail, web, market)
2h of activated WLAN and deactivated sleep to copy stuff from pc to Defy
1,5h music (radio)
and 1h (and 6 minutes lol) of phone calls
After that day, i still had 30% of battery.
The maximum i reached were 75 hours including MY normal use with some mobile internet, some texting and 1 or 2 calls...maybe an hour of gaming at most.
I did not charge it first when i got it, because the battery was at 80% already/still and i wanted to play around.
Current running time: 26 hours...i activate plane-mode at night from now on. Low 70s now.
Everything at minimum display brightness (30%?)

In my opinion, a task killer is absolutely necessary.
All the apps launched keep consuming RAM even if they're not in use. I brought back 106 mb last time i performed a task killing! In most of the cases less ram means worst performances / more work for cpu.
I LOVE the Galaxy Nexus, but the rate at which the battery discharges is just ridiculous. I'll use the phone for 15 minutes doing things like Twitter or Web Browsing, and it'll discharge 5% in that time. To me, that is horrible. I'm being really conservative too. Throughout a day I try not to play videos, games, or anything else intensive because I know it'll ruin my battery life. Even on standby it discharges 5% in an hour. Typically I lose about 10% an hour and my max has been 12 hours so far.
I have auto sync turned on and keep the screen low when possible. I NEED auto sync on because of the nature of my work. Compared to my iPhone 4S battery is downright pathetic.
Today my usage consisted of one phone call, a few text messages, lots of Twitter, and light web browsing. Nothing too crazy. Again I'm being really conservative with my usage whereas on my iPhone I can do whatever I want and not worry. I'm just not seeing how people are getting 15+ hours and claim heavy usage. I'd love to believe that! The battery drains so fast during normal usage it may be a deal breaker for me.

It sounds like your definition of light usage is wrong.
I wouldn't consider heaps of twitter and some web browsing light usage. I would consider it moderate usage, in which case you seem to be in line with everyone else.
I agree with you in that the battery life isn't quite what I would have liked. Ideally I wouldn't have to worry about battery at all, and I'd be able to play games and browse the web as much as I like, but for normal usage it's fine.
The next Nexus though, man, that will only have to be charged once a month. I can't wait.

Twitter hardly taxes the processors at all. Refreshing it every so often should hardly take any battery life at all. Web Browsing I can understand, but my total time browsing today probably amounts to 10 minutes total.
I wonder how much of the drain is attributed to the 4.65" screen. It's a monster.

I expect the battery life go improve within the first few cycles. I had a similar experience with the Nexus S last year.

People using a G2x claim to get a day and a half... I'm lucky to get out of work. Push email for work is to blame I think. I get tons of emails (100 a day) and I think its taxing. From your pics, the screen used over 50% of it. That's a lot.
Sucks.
Also make sure your aren't turning on the screen every 5 minutes to check the status. Since your coming from an iOS, are you closing apps properly (back = close, home = minimize).
I'm not saying your crazy but just saying.

I had the same thing happen with the Nexus One. The battery wasn't that great but, got better after a few charge cycles.
I've never had a Android phone that could match the battery life of the Iphone. I can sit the iphone down at night without putting it on the charger and, if it's at 100% it will be at about 90-95% when I wake up. I did the same thing with my Mytouch 4G and, it was at 15%
To the OP, I would recommend keeping a charging cable with you when you out and about especially in your car. I've had car docks with a few of my android phones and, always keep the phone docked when I'm driving somewhere. It really helps.
What you also need to remember is this is the first release of ICS and is still in development so battery life my be improved in the next update. Like you mention iPhone4S there was massive battery leakage in the first release of IOS 5 which Apple apparently fixed in the newest update.. So maybe in the next update we can expect some bugs ironed out.
Used to only have ONLY 2-3 hours screen ON on my Vibrant so I know how SAmoled looks like.
I know iphone battery is good, but you need to consider the screen size too..
Get a spare battery with your "light usage", but I am thinking how much would it cost becoz of the NPC antenna.
Too good thing is, unlike iPhone, you can buy a spare battery and carry it with you.
3 hours of screen use is what the problem is. That is a long time. I wouldn't complain about that at all.

I already said I didn't play any games today and my screen brightness is low. For some reason Shadowgun stays in the battery info screen. I played the game two days ago and manually closed it out. Even after rebooting the phone its still there.
I'm being 100% real, stop trying to make excuses or act like I'm an iPhone fanboy. The Galaxy Nexus combined with ICS is the best phone I've ever used! I'm just terribly disappointed with the battery life.
Twittering all day is sucking up battery because of all the data use. Dude, youre not a light user with 3 hours screen time moderate, possibly heavy depending on background stuff sycing automatically. You have some tweaking to do, not whining.

3 hours is not that much. Seriously. It shouldn't be damn near dead after 10 hours. Imagine if I decided to play a game for 15 minutes or watch 2 YouTube videos.
I bet if people were getting an hour and half with this phone, all the fanboys here would say the same thing. "Man, an hour and a half is a long time! You should be happy with that!".

I've tested out the battery difference by turning off auto sync. Doesn't make a difference at all. Fact of the matter is that the battery drains like crazy when the screen is on.
I'll just turn my phone on because actually using it is frowned upon here.

I will defer to the xda mods if they think this thread is redundant. I have been using my Galaxy Nexus now for ~3 weeks. During that time, I have seen my daily battery life improve from ~10 hours to a little over 24 hours before needing a charge.

2.) While on battery power, set your Nexus display's brightness level to ~30%. I've found that particular brightness level to be a sweet spot. Auto brightness does not work for me, so I hard set the level. I am able to get between ~4 to 5 hours total of screen time a day on battery power at that level. There are many Android Market apps/widgets that will allow you to set power profiles depending on your location and power draw and/or charge.
3.) Along with conservative display settings, I turn off cellular data entirely, or only use 2G (Edge) when connected to a WiFi hotspot. I have an unlocked I9250 Worldband GSM Galaxy Nexus, so I'm unable to address 4G LTE. But if I did have access to 4G LTE, I imagine the only time I would use it would be for tethering while the phone is plugged into a power source. Regardless, 3G (HSPA+) can be a significant power draw, and 4G doubly so. When on WiFi, 3G and/or cellular data is off entirely. My guesstimate is this saves me between 15 - 20% battery power throughout the day.
4.) I set application accounts to sync and updates only when on WiFi.
5.) Avoid rebooting or powering off the phone while on battery power. I've noticed a loss of between ~2 - 5% when rebooting the phone on battery.
6.) No live wallpapers, and the image I do use for a wallpaper is very dark. I set the homescreen widgets to nearly transparent and white text. I'm certain this conserves battery power, but by how much I can't say. [REFER]:
7.) During a typical day for me, I'm constantly using Twitter, Google+, Facebook, Gmail, the ICS Browser, TapTalk, and of course the homescreen widgets connected to network services. I would consider myself an average to heavy user depending on the day. All Gmail is pushed. My widgets update between 1 - 3 hour intervals. You can tell by the screenshot provided my WiFi signal is always on, my Awake and Screen On times are between 4 to 5 hours total of the 24 hours available. As you can see from the screenshot, during that 24 hour period I did not top off with a power charge during that time.
Any other tips for extending battery life are welcome. I hope this helps.
Cool. I keep my phone plugged in when I am in the car or desk and that seems enough for me without having to compromise. 4G is a real killer
Are you using Tasker to kill data when on wifi and enable it when not?
I was under the impression the OS did this automatically

FYI, the original poster is a HSPA+ user. Entirely different experience from a LTE user.
Err... if there is anything I take away from this thread, its: "If you want 24 hours of battery life on your Google Nexus, don't use it."
It's hard to say for certain, but it sure doesn't look like you used your phone very much over 24 hours. :|

Total time the screen was on was between 4 to 5 hours total out of that particular 24 hour period. Depends on your definition of "use", but I've seen definitions of moderate to heavy smartphone use defined in various forum posts throughout XDA somewhere between 3 to 6 hours of screen time on a single charge. YMMV.

I'm certain it was over 4 hours, I remember digging into the screen stats under the battery settings before taking a screenshot. I don't have a screenshot of the screen stat window during that 24 hour period.
Don't believe me? I don't really care. I have nothing to hide and nothing to prove. Just relaying my experience with the GN battery over a 3 week period.
I would rather keep 4g on and just charge throughout the day. Why pay a premium if you're not going to use it, but I suppose you don't have 4g so you don't care.

This. Doesnt look like 4-5 hours screen time because the phone isnt awake enough.

I don't see a problem with the battery life for the size of the phone.
I'm sure it would go a day and a half before needing a charge with my usage (which I consider 'normal') but I plug it in everynight while I sleep anyway.
The battery life definately improves after a few charge cycles.
I agree with sc4, you basically are saying not to use the phone. You do not have to take such extreme measures just to get good battery life. I get pretty good battery life and I don't disable anything.
Well I thought it was a nice post. Jeez. Especially if you compare to most of the crap that comes up in the general section.
I couldn't find where he said "dont use 4g der". I believe the idea he presented was to turn off 3g/4g while you're on wifi. Do you need 4g AND wifi? Easy, common sense. Thumbs up.
Just so you know: WiFi uses the same amount of power to transmit/receive data as 3G. You're not saving anything by turning off the 3G radio while on WiFi since the only thing it's being used for is phone calls and text messages.
In addition, being in WiFi all day long can *really* improve your battery life. It's easily the biggest thing on your list. Why? Because the cell radio isn't constantly trying to maintain a data signal to the 3G towers. It maintains a connection but it doesn't have to negotiate for it almost at all...saves a lot of battery life.
Oh, and that Battery Calibration post is ridiculous. When you first get a phone just discard it fully then charge it up fully. Do it once every few months for the life of the phone and you'll find you maintain great battery life. Outside of that, keep it plugged in as *OFTEN* as you can to maintain longevity.
Also, according to your screenshot, your screen was on a *maximum* of 3 hours, but most likely around 2 1/2. That means the data connection most likely wasn't used much more than that, as well. That's very light use over a 24 hour period.

Well, no, you wouldn't...but it turns off the LTE radio when on WiFi anyway...so that's a moot point.
One more tip:
If you use vibrate on keyboard, shorten it to as low as possible.
This is possible using SwiftKey

Agreed that is not 4-5 hours of screen time. It is blatant in the graph u provided. Look at the screen and awake times. Here is mine with only 2 hours of screen time but over an hour of voice.

To push more, set the animation etc. to 0.5x in the developer options. This should reduce the cpu usage a little bit.
And turn off auto rotate as it consume quite a lot of cpu power. Most probably this is just a bug, there has been a report in the Google code bug yracking.

I agree. I did not get a screenshot of my screen time when I took the screen pic of the timeline graph. I was relying on memory, but after comparing republitarian's pic which has roughly the same timeline span, looks like my memory failed me. Mine is somewhere between 2 - 3 hours of screen time as well. My bad.

Before you all start to yell at me, hear me out. I always see people posting screen shots of their amazing battery life, but there's just one problem -- it's not really "real world." What I mean is that I always see people with sync off, brightness 10%, gps off, data off, and wifi on. I don't think it matters that much when a phone can last 20+ hours sitting idle with 20 minutes of screen on time. I want to see people using 3G/4G with sync, gps, bt and all the good stuff ON.
That being said, yes I have searched the forums and I couldn't really find any thread like this so here it goes. If you feel like it's a double post or anything, just let me know and I'll delete it! Thanks.
I don't have a screen shot, but the "best" battery life I can get is ~14 hours with 2 hr 30 min screen on time.

What you consider 'real world' may not be what others consider 'real world', perhaps there are some people who just don't use Bluetooth, leave WiFi on even when they have no network to connect to or have sync set up for things they don't need syncing for.
At least 4 hours screen time with:

Daily, I use: Netflix/Poweramp/Spotify/Reddit on my daily commute. Phone/Poweramp/Spotify/Reddit/Browser+ in between commute.
I know, that's why I put "real world" in quotations. Obviously people will have different uses with their phones, but I just wanted to see what people were getting in terms of battery life with 3G/HSPA/LTE actually on... most of the screen shots I see have wifi on all the time with 20 minutes of screen on time, and that's not really I'm looking for.
hmm
I'm not getting anywhere near those numbers with stock rom enough for me to remove exchange account from the phone
I got about three hours twenty a few days ago, I don't know how, I am usually lucky to get more than two. I have weather sync every four hours, push Gmail, I usually have ~10% brightness but just lately I have been using auto, which eats battery.

I hot plug core 1 when the screen is off, use aggressive SetCPU profiles, don't let anything but weather sync. It doesn't really bother me, I'm never far from a power socket!
What is the point of having bt, GPS and sync on if I don't need it? I understand the threads that have 20 minutes of screen on time are stupid, but my real world use doesn't include bt or GPS, and sync only when I need it. I'm at 43% with 2 hours of screen on time.

Totally agree with your call. We should not need to kill some service with the goal of prolonging battery life.
Real world should be defined as on a typical day,with services not intentionally shut for saving battery ,what is the battery time. For example,Facebook loading uses GPS all the time. For another example,I don't need to turn off bt with purpose of saving juice if I use them 3 times a day.
But if I never use bt for a week, it make sense to shut it.
Will monitor and put here. I am on gummy 0.7 with Francisco kernel 15.1 . With 4.0.3 LTE radio and 4.0.2 CDMA .
a disturbing note: I found the combination of above radios works the best for me,no I did not dial *288 sth

50% brightness, location services on, GPS off and I get around 3 hours of browsing. Easily makes it through my work day, which is all I care about
GSM. Everything stock and on except email sync off (annoying for me).
2.5-3.5 hrs screen time.
Standby time is excellent. Could get at least 30 hrs.
Only screenshot I have, but I tend to get at least 20 hours with regular use.
Charging my phone at night, unplugging it before I go to bed around 10, wake up, work, get home around 5pm and plug my phone back in around 10.
Screenshot has some overnight in it, but still looks good, WIFI on always, constantly losing signal because I live in a rural area.
In total standby, I could probably get more than 30.

I get 2-3 hours screen on time, that's browsing , taking pictures, YouTube, and apps.
And I get 8-12hours all up before a charge.
This is pretty good but I would say that 2-3 hours of use is light to moderate , heavy use would be 4-6 hours and for that you would need an extended battery

Very similar to my usage. Only had it 2 days though so haven't really fallen into a "groove" with the device yet.
GSM with the Korean 2000mah battery, I am down to around 15-20% left after 6-7 hours. Then the screen have been on for around 3 hours.
I am lucky to get 2 hours of screen on time, but most of that time is playing games. Stock GSM battery, ARHD stock kernel + MID brightness mod; WiFi on at home, BT off (rarely use it), quite crap signal at school.
I'll see what I get today and take a screenshot. I want to buy the extended battery; I won't remove the MID brightness mod, the screen would be way too dark on auto.
I received my Galaxy SIII on Monday and haven't been able to complete a full day with light to moderate usage. Yesterday after about 11 hours of mainly standby / light usage I had about 3% battery before I was able to charge it.
Is this normal? I'm coming from an iPhone 4 (this is my first android phone) and was quite excited about this. But if I can't make it through the day what's the point. I have noticed at times that the back of the phone can get quite warm, not hot, but definitely warm. Perhaps I have a faulty battery?
I've heard Android can be a bit notorious for poor battery life, but I didn't expect that I wouldn't be able to use it for the fear of the phone not lasting the day.
My iPhone 4 I could use it quite often throughout the day and end the day with close to 40% battery life and if needed I could last through the night well into the next day without a charge.
Will I have to carry around a spare battery / charger at all times.
Here are some screen shots from today. I've been awake and unplugged for nearly 3 hours, barely used the thing and I'm already at less than 70% with HIGH cell signal standby.

Hmm, looks like yours may be fairing better than mine based on your usage. Looks like you used it for a good 40 minutes.
When I use mine I can watch the battery percentage drop. I really hope that this is an issue with my phone and not the phone in general. I really like the phone and it's a nice change from the iPhone (little quirks here and there but still nice).
However, if the battery life is this bad (bad IMO perhaps this is actually good), then I think I'll have no choice but to return this phone - assuming I can. Otherwise I guess I'll have to drop the money for extra batteries.
I've gone as far as basically making email manual. I've turned off that stupid S-Voice thing so it won't wake up by me saying "Hi Galaxy". Guess I'll turn off WiFi and GPS (though I feel I shouldn't need to). I have battery saving mode on as well and I've dimmed the screen down to what looks like 20%...
EDIT: also, the maps that used 6% of total battery usage was me just taking a look at the widget and disabling it. Less than a minute of usage...
Your phone is not sleeping. Install better battery stats to see what is keeping it awake.

Unfortunately I can't do much about that since I'm at work
Do you have a recommendation for a good battery monitor? One that preferably doesn't cost money?
When it was awake I believe I had been messing around with it. I've checked it again and it hasn't been awake that often (just spurts). Looks like it's periodically syncing with my email, while I realize this will cause the battery to be drained I wouldn't expect this to be too large a deal. I would think I should be able to have my phone idle and still be able to receive emails without it causing too much of an issue. All my accounts are set-up through IMAP (minus my exchange account - which I've set-up to run manual during peak hours and check once an hour during non - peak hours) so the emails should be pushed to the device since I shouldn't be polling the servers (although it's possible I don't know too much about IMAP....).

I just got and activated my S3 on Wednesday and am having the exact same problem. I'm also on ATT and am coming from an iphone 3GS. First day I had the S3 I barely got 8 hours out of it, most of that time in standby mode and with nothing but the stock apps installed. Yesterday I cycled the battery and drained it to completely dead to where the phone wouldn't even try to turn on. I then charged it to 100% with the phone turned off. I then unplugged it to see how much battery life it would drain on standby overnight. In about 6 hours while I was asleep it went from 100% to 93%. Then I left home and between that time and now, 7.5 hours, with minimal use which included less than 20 minutes of phone calls, downloading 3 apps, syncing email a couple of times, etc.. no games, no videos, no music, no internet browsing, nothing....
Battery is now down to 24%
Screen - 1h 42m 26%
Android OS - 10m 7%
voice calls - 17m 5%
and the rest of the stuff at about 5% or less,
basically, in 7.5 hours of doing almost nothing, with power saving mode turned on and juice defender also active, my phone has gone from 93% to 24%.
Before I got the phone I read several reviews that said the battery life on these phones was supposed to be excellent. I can't imagine that this is what would be considered excellent. My iphone, which I replaced because the battery was dying, would easily last twice as long as this and that's with heavy use including games, pandora, youtube, and internet browsing.
Aside from the short battery life I'm also experiencing horrible wifi issues. On my wifi at work it will constantly disconnect and reconnect over and over. I had my iphone sitting next to the S3 and the connection was rock solid.
I contacted samsung and ATT and they did not have any suggestions or solutions but the guy from ATT did suggest taking the phone to an ATT store and they would give me another battery to try and if that didn't work I could exchange the phone.
I hate running around exchanging stuff but I'm very disappointed with this phone so far. Half the battery life of my iphone and horrible wifi connectivity isn't what I'd expect from a phone which has been touted as being significantly better than the iphone 4S and possibly even the iphone5 when that's released.
Any suggestions? I'm really trying to love this phone but so far...meh....not so much..... I love the screen, the interface is very cool, it's lighter than my iphone, but if I can't get more than a couple of hours of very light usage and no solid wifi connectivity, I don't know.... Once I get these problems ironed out I have a couple of other total newb questions about things I need to do with it but first things first...if I can't solve these problems, this phone won't work for me. Hope you guys can help! :good:
I'm glad (but not glad) to hear I'm not alone. It really is frustrating. I've been in the process of charging my phone which is taking a long time in and of itself (although I am connected to USB on my PC). It's been plugged in for 2 hours and gone up 24% eh.
I'll probably take it to the AT&T store and talk to them about it. If I can't get is solved I'll probably exchange it, but that exchange would have to be a guarantee that I'd either get the iPhone 5 when it comes out without having to pay full price, or perhaps the HTC One X, but I hear that isn't much better either. I have a friend who has the HTC One X (or the variant of it on Sprint) and he get's two days of battery life with some gaming even.
I do not want the 4S since IMO it's a worthless upgrade from the 4.
I'm located in the suburbs of Chicago so I have 4g LTE just about everywhere, granted my signal is a bit weak in my building... by a window.
If you come up with anything let me know and vice versa.
Yeah, you're definitely not alone. I've read some other posts on this and other forums of people complaining about the same thing. I have 30 days to return it so I really want to see if I can figure out how to make it work. If not, I'm going to do the same thing you're thinking of -- take it back and hopefully they'll let me go back to using my old iphone until the iphone 5 comes out, then get that one at the new contract price. Like you, I have zero interest in the iphone 4S.
I have to say, this is really frustrating and disappointing. I was expecting an "iphone killer" and instead I've wound up with a phone that with light to normal usage is pretty much dead by 3 in the afternoon. I can't work like this.
And like you've noticed, it does charge very slowly. Even through usb my iphone would charge very fast. 20 minutes in my car would give it about 15% more charge. The S3 goes up maybe 2 or 3% in the same time. I can live with this but not with the battery life or wifi problems.
btw, I'm trying another full discharge cycle tonight to see if that helps any. I really hope I can get this resolved. When I got the phone I started shopping for accessories like a car dock, screen protector/case, etc.. and was ready to order some but held off when I saw how crappy the battery life was.
No one has said this yet, but you are using a different version of SGS3 from us. You should go over to the ATT LTE boards and get help.

I am also in the Chicago area weak signal will destroy your battery so that could have a LOT to do with it. The sprint One X also is 3G only for the time being, so it doesn't have those life-sucking "4G" issues.

I just got and activated my S3 on Wednesday and am having the exact same problem. I'm also on ATT and am coming from an iphone 3GS. First day I had the S3 I barely got 8 hours out of it, most of that time in standby mode and with nothing but the stock apps installed. Yesterday I cycled the battery and drained it to completely dead to where the phone wouldn't even try to turn on. I then charged it to 100% with the phone turned off. I then unplugged it to see how much battery life it would drain on standby overnight. In about 6 hours while I was asleep it went from 100% to 93%. Then I left home and between that time and now, 7.5 hours, with minimal use which included less than 20 minutes of phone calls, downloading 3 apps, syncing email a couple of times, etc.. no games, no videos, no music, no internet browsing, nothing....
Battery is now down to 24%
Screen - 1h 42m 26%
Android OS - 10m 7%
voice calls - 17m 5%
and the rest of the stuff at about 5% or less,
basically, in 7.5 hours of doing almost nothing, with power saving mode turned on and juice defender also active, my phone has gone from 93% to 24%.

Almost 2 hours of Screen On, is not bearly doing nothing. It's nearly a 5" light bulb you're leaving on.
Your signal may also not be as good as on your iphone in the same areas. But both of you seem to be on par. Yes android devices don't last as long as an iphone. There's more to do and more do on an Android than an iphone. You're also in your honeymoon stage..
Did some research found this link to force hspa so it disables lte or wont connect to it. Going to try that. Not sure if this disables the antenna and you'd still get the battery drain.

No you will not experience the battery drain if you disable LTE in this way.

If I'm understanding you correctly, are you saying that the ATT S3s are different than the other S3s and are expected to get less battery life?
btw, where are the ATT LTE boards you're talking about?
