i don't know if I received a "dud" unit in the sense, but i have noticed INCREDIBLE battery life on my Nexus S with moderate use. the first day i had it (2 days ago), I charged to 100% and then started using it. I would say I did about an hour of browsing, an hour of talking, an hour or so of texting, maybe 10 mins of GPS use, and an hour of unlocking, rooting, etc. also just left the phone unplugged from charger overnight. on the first charge, there was a point where i was at 1 day 12 hours and 16 mins on battery and still had about 40% left or so. I even have a pic of the battery usage page I will post. *it should be noted that i turned off wifi, gps, etc when i was not using it. and did not use a live wallpaper. *edit: i also had background sync turned on the entire time. syncing gmail, contacts, calendar, etc.

That's over 2.5h "display on"-time and still 40% left, sounds quiet impressive. There's something wrong with your phone, in a good way.
If your numbers aren't accurate though, it's "normal". Idle use of 1% and less per hour w/o widgets and background active apps is nothing special.
it may also be related to you being on AT&T. i've read in various forms where people say that AT&T's mhzs (don't know the technical term) use less power than T-Mobile and WAY LESS than Sprint, which results in better battery life (the whole CDMA vs GSM thing).
The Sprint CDMA ones seem to have the most battery issues.

I'm actually seeing an increase in battery life with GRJ90....
My phone without mobile data on lasts about 20 hours...with mobile data enabled, but not necessarily active because i am usually on WiFi the battery life is reduced to maybe 5 hours...pretty bad...mobile here is Edge
Could it have anything to do with being in a bulding with thick walls? maybe the phone is using more power transmitting just trying to figure out where the cell is?

While it is true that bad signal harms battery life, 5h is ridicously low. Those 5h, how long is the display active in that period?
Check the battery status and see what is draining your battery so fast.
Try to change the WIFI rules from "turn off wifi when display is off" to "never turn off wifi" (you can still disable wifi the normal way, it just won't time out if there's a valid connection available), you can also set your phone to "2g only", if - as you said - your area has edge only anyways to further safe battery.

well its not a cdma vs. gsm thing, if sprint where able to purchase those frequencies they would have and it would have been different.
Much the same with tmobile them being so late to the game those are the best freq. they could obtain.
much like how sprint/clear's wimax sucks really due to bands it had to run on.
during the 5 hours, display is on for very little time....wifi is not a problem..when the display is off i still get email notifications and all that...i dont turn wifi off when i go out to the street and its constantly searching and i still get like 20 hours...but with 2g on, battery goes fast. I am not worried YET though, as my time at this 2G only location is about to end soon, then i will test 3G. I will spend some time in the US and plan to get simple mobile there...i belive that will be 3G with the Nexus S.
I do more tests once I get there...here I cancelled the 2G data this week since it drained the battery and i barely got 20kbits downloads (literally useless).

Out of curiosity, how much time were you getting before and after the update? I sold my two Nexus phones because I was getting maybe 5 hours tops with average (not heavy) usage!
I am hesitant to try the Nexus again, unless everyone says the update made the battery life much better for the CDMA version.

This is around what I'm getting (without a LOT of Wifi usage, maybe an hour 1 tops.....the rest is on 3G). The way I like to test my battery is to see how far I can go WITHOUT Wifi because of course it will last forever with Wifi on (should anyway). I can average like 15 hrs a day, with around 3.5 hours of display time on (really depends on what I was using it for) after the update....
Along with that, the new Gmail update will most definitely increase the battery life even MORE now because I keep EVERYTHING on, including:
- GPS AND 3G location services (use to turn 3G location services off, but the battery has been so nice on the Nexus I never found the need to anymore)
- Auto-sync turned on for Google Account services (Gmail, back-up, etc.) and Exchange account
- Exchange Push account (syncs 3 days worth of stuff)
- Auto brightness for my display (I drive 2 hours to work and 2 hours back, and on the way home the sun is constantly on the screen so it has to auto adjust for the brightest setting for however long I use it driving home from work).
I don't have many accounts syncing or anything (not into Facebook, although I have one) so that may be why. But prior to the update, my 3G signal was weaker so my battery would die a little faster (although I've ALWAYS been able to make it through a day of work with my Nexus). For me, the battery life has always been the best of any smartphone I've used, but after the update it seems a little bit better; not DRAMATICALLY better, just a little better (still can't touch the iPhone 4 on-call phone I had for work for a week......didn't have to charge that thing but one time during that week )
Again, this is with the Nexus S 4G
I meant 5 hours when it is sitting idle most of that time. Maybe 2-3 hours of actual usage.
I have going long as 15 hours with normal usage.

You seem not to be on Sprint (cdma) so this particular battery issue is not related to you...
I'm really amazed to be hearing about all of these phones with such terrible battery life. I have a Nexus S 4G & my battery gets me through half the day now this could be due to the 1750mah battery I'm using & then I'll switch to the stock 1500mah to finish out the day. I consider myself to be a fairly heavy user because I'm always on it sending text, emails, web surfing, phone calls, utilizing it as a hotspot & the only thing I've noticed that really puts a drain on my battery is downloading massive amounts of data, streaming data & watching movies on Netflix. I even use it to game online with my PlayStation 3 because I'm in an area where there is no internet & signal strength is all but none. I guess I too have an anomaly but nothing like a day & a half I wish. If there is anyway to extend battery life any further I would love to know.

I get amazing battery life on my Nexus S 4g. I owned the Epic and the Evo before the Nexus S and I gave up on those because of the battery life. I'm usually at over 30% at the end of the day. I do have the latest stable build of netarchy installed. I undervolted using setcpu and have 1 profile. Underclock to 200mhz when the screen is off. I sync my Gmail as well.

Hi to all!
I'm thinking of buying either the Legend or Desire. There are two things that are important to me. The battery life and storing applications on the memory card. I suppose that the latter will be taken care of by the upcoming update to Froyo (if it ever happens!). How about the battery life? How long does it last on the Legend? Would anyone have any experience with the Desire vs the Legend on this? All comments appreciated!
Thanks in advance!!!
I don't have experience with the Desire but my Legend performs battery wise as expected from a smartphone I guess.
After the last update I discovered for example that leaving Google Reader open in the browser in the background drained power, so I now leave the browser always on the google homepage or kill it altogether when I'm not using it and I've seen an increase in battery life.
Anyhow, I give it a pretty intense use, on a work day I listen to podcasts on it for some hours at least, I connect it to my car bluetooth on the commutes (40 mins average total), read email, etc. And it lasts me the full day without problems, usually ending the day with 30% or more battery left.
It obviously depends on how each one uses their phones, as tricks like the Reader one I mentioned can make a difference.
The Legend seems to have slightly superior battery to me. My legend ends the day at about 30 percent after 2 hours of Bluetooth stereo playback, and plenty of latitude use and web browsing. My partner's new desire ends the day about about the same but without the music playing I do.
I was jealous of the desire when my partner bought it but If I had the choice of legend or desire again, it would be a hairline decision to buy legend again. If Legend had live wallpaper I would choose legend without doubt.

My battery life is even better than my old dumbphone. With medium use and pretty stringent management (ie. a task killer, bluetooth and wifi off unless I need them), I can get about five days on a charge.

Are you sure you are using the original battery ? I have never heard anyone reporting 5 days on any smartphone on even minimal usage. Legend seem to give 1 to 2 days max on minimal usage.

I have on two occasion to manage get three days but five days? Naah, not with the original battery.
Well if you disable APN the thing can last 5 days, but with net connection active definitely no way.
I can believe he gets 5 days out off this phone. I can get 3 days out of it with very good reception, some hours of browsing and 20 texts a day. Almost no calling and 3G always on AND WITH A GOOD TASK KILLER I always kill almost every app before putting it in standby you just need to know what you can and can't kill.
I can do 3 days with low use (maybe 10min calls and 20sms a day) and APN off most of the time.
With APN on I don't think it will last more than 2 days max
Just to clarify, I do turn off my mobile internet unless I'm using it at that moment, and yes I'm using the stock battery.

Sure, if you turn everything off it'll last a few days, but then might as well carry a dumbphone
Hey all,
I've been using Azure 1.0 on my Legend.
In case anyone is wondering what battery life is like on this ROM [I know I wanted to know before I decided to run it...] :
I've just got the best usage for this ROM in terms of battery life, since I started using it [0.5].
I haven't gone for Azure 1.0.1, and have stuck to 1.0 as I didn't have any APN issues...

Voice calls = 1hr 3m 15s + SMSing
WiFi = 6hr 46m 46s
For the hours that WiFi was not on, Data [H/3G] was always enabled.
Approx 1hr 45min of browsing
Approx 10 emails received and replied to
Battery life was pretty poor when I first installed the ROM.
Then I used SetCPU to help....but it didn't seem to help too much...
Now I am seeing better battery life, like the above.
No idea if this is good/bad for this ROM, but for me, its the best I've seen yet....
...though still probably not as good as I first saw on the stock ROM before the update which messed up the stock SMS app was pushed out...
18 hours ~ 24 hours average. 1 and a half day or so if I'm lucky.
2G network. only switch on 3G when it's needed.
Wi-Fi, gps and bluetooth if needed. If not, it's turned off all the time.
always leave my Trillian (MSN/YM/gTalk) turned on almost all the time (like 75% of the time).
WhatsApp for 24 hours.
Mail fetching every 4 hours.
Twidroyd fetching every 15 minutes.
Urbandictionary widget fetching every hour or so.
15 minutes of call average.
Texting about 10-20 times a day.
And data counter widget running all the time.
Rooted and using a nice clean ROM called "CleanEclair 1.6.2"
Got a good Task Manager too.
It's definitely better than my old iPhone 3g.
BUT, if you are asking "Desire or Legend"
I may choose desire for it's better hardware.
PS: Sorry about my bad english.
Just to echo previous statements about battery life, I too get an easy 24 hours from my UK Legend. It usually has at least 30% charge left when I plug it in at night (10-11pm), this is from about 6am. As I type this as 4.30pm it has 69% left.
I leave data and wifi on all the time but only enable GPS & Bluetooth when needed. The phone connects by wifi at home but is in a marginal 2G location when I'm at work (cheers, Vodafone!) so probably has to work quite hard to keep connected to the network.
Google services and Twitter update constantly, Facebook every hour.
Don't run any task killer apps as I found they made naff all difference.
I do watch how many browser tabs I have open and what's on them thought as I notice that some pages really suck the battery dry.
Navigation is the real killer on the Legend (or any Android I guess); the combination of screen on, GPS enabled and heavy duty data use means it can go flat in as little as 3 hours. A power cable in the car will only supply 500mA, rather than the full 1A that a main scharger will, so it only really slows down the drain on the battery.
Other than that I expect the phone to fit my life, not the other way round. The effort that some expend to micro-manage their battery life really baffles me!
I get terrible battery life...
Typically 7-8hrs , now I use it for work but today I did 30ish minutes of calls, + maybe 1hr's worth of reading emails, sending data etc etc etc.
From looking at the "battery" part of the settings/about screen I can see that Display seams to be the thing EATING the battery..
is this normal?? I do use the power widget and put the screen down as low as it goes when I can however im really shocked at the power usage..
Ive tried using a task killer (advanced task killer) and JuiceDefender and neither make much difference...
any comments?? am I being realistic? I used to have a blackberry 8900 and it would easily last me a whole day , doing the same email load, websurfing, syncing etc, might even last 1.5days but I tend to plug the legend in whenever I can....
Is this normal???

Yup. Try lowering your screen brightness and see the difference. Screen and gps is the most battery-hungary.
Everything depends on how you use your phone. Try to avoid GPS and max screen brightness. And always remember to kill aps with any of the app killers, after you finished with it.

Good advice. Except on the task killing. Google around why task killing is not healthy for your phone.
my battery doesn't seem to show the correct level...I can charge it overnight on the mains an in the morning it has only got to 38%. Take the battery out and it goes up to 60ish%. Phone will last about a day, but can't seem to get a full charge into it.
You may notice if you turn off Sync from the power widget and turn off cell data from the wireless settings menu, you can get the 4 to 5 days of standby. Of course then you have essentially a dumb smart phone.
Cell data is primary power drain in typical usage. That is partly why android tablets can go for weeks without a charge but phones just last a day (of course tablet has much bigger battery). Because of the variance in cell signal strength depending on location, you'll notice variable battery life especially when traveling. Also, having sync enabled wakes up the phone frequently even with cell data off. You can observe this in the battery use graph.
Juice Defender
https://market.android.com/details?id=com.latedroid.juicedefender&feature=search_result
Juice Defender uses this knowledge and turns off wireless data when the screen is off. Giving 1.5x battery saving. The pro version is even better and smartly turns off sync and only syncs at users option e.g. 30 minutes up to 2 hours.
Result is much improved battery life on any android phone with minimal loss of "instant" type notifications for email.
Apps like JD defeat the whole purpose of having push email/calendar/talk/voice e.t.c on a phone. I like use Gmail/calendar/e.t.c and like having those apps push info to my phone instantly, ofcourse at the detriment of battery life. Throw in apps like Skype and Trillian that i sometimes have running in the background and you can see where it's not too viable to have data turn off when screen is off. I thought the whole advantage to push anything was that it would save on battery life vs having to pool every x amount of time.
If JD Pro like you say only pools for data every 30 mins when screen is off then it might be worth it to some folks.
My thinking is that Android phones and good battery life do not go hand in hand. I've been wondering whether to stop using the Gmail app and experiment with setting it up in K9 mail since K9 mail supports IMAP idle push (and pushes my .Mac and AIM email accounts just fine).
Battery tech in just has to get better. I do get jealous of my friends iPhone battery life with all the push notifications going on and music and video playing, he still pushes 2 straight days sometimes on one charge. Me, i bought 2 batteries and a desktop charger on eBay for 9.99 and also have an iGo 1800mah portable dual usb battery charger thingy that i toss in my man-purse. So battery in NS4G (which dies by ~5-6pm usually), 2 spares and a portable charger.
I've always had a negative opinion of JD, but i'll give JD Pro a try and see how it impacts my need to instant gratification of push..
Let us know how you fare with the JD. I don't want to buy it if it doesn't improve battery life. I recently invested in the Just Mobile Portable USB Power Pack and that helps if you're away from a computer and a wall plug and need to get your battery recharged.
I use jd when I'm at work because a lot of the time I am in the ffield and just leave my phone in my car. If I need to call or text someone I just use the company blackberry.
I can come back to my phone after hours and only have 2-4% gone on my phone. Then I just use the toggle widget to disable jd when I have my phone on me after work and on the weekends.

I used jd for half a day
I am a huge slacker (radio) and it caused my radio to wig out bad
I am sure this was the culprit even when disabled
Turning off data while screen is off is akin to stop and go traffic and your car getting worse gas mileage, everytime it turns on you have to reconnect and search for signal actually using more battery. Also, why buy a smartphone and not want 24/7 instant data access.
I keep wifi set to never sleep, and leave 4g radio off and location to gps sats only and get through my day with 0 issues on my battery. I took my phone off charger at 9am yesterday and now its 130am and i still have 20% battery, 2 gmail accts syncing mail and calender, 1 exchange set to push, twitter, google+, score mobile tracking 3 games today. Keep your backlight low and manually turn off the screen instead of waiting for it to timeout.
This is my usual rationale. I shall still evaluate JD for another day just to see if it actually does anything useful in my use case, otherwise I'll just carry around 2 spare batteries fully charged.

WHAT is it that you people do that you need to carry TWO batteries lol.
This thing lasts me all day. I mowed my lawn for 2 hours the other evening streaming slacker the whole time and barley made a dent in the battery.
But then again I have been used to my Iphone which had major battery issues to me. Where as this I might throw on the charger at work for a few or charge in the car while i drive, the Iphone I had to basically RUN everywhere on a giant wheel to continuously charge the stupid thing.

I swear I'm not war driving or trying to crack nuclear codes on my phone. The battery just drains like I can't explain. I'm not a power user, nay, regular use. For example, 1 Gmail account pushing mail/contacts/Calender/Google+, K9 mail with 3 accounts and that's it.
I hardly dare even use it to play music or videos (have a Galaxy Tab 7 for those uses).
I think the radio isn't efficient enough and just uses too much power (at least on some units I'd hypothesize).

I'm definitely doing away with juice defender, and just carry 2 extra fully charged batteries on my person and set certain apps not to sync or sync. Disabling 3g and wifi adnaseum defeats the whole purpose of having a smartphone and I find myself managing JD more than I care to.

i have only had my phone for like 4 days. Between mine and my buddies S we think the biggest drain is the screen.
it always shows up as the largest draw especially on auto.
Dont keep it on auto. keep it LOOOOOWWWWWWW.
I keep a brightness widget and if it gets to dark where i am (one in a thousandth of a shot so far) i tap it up a notch or two.
then reduce it when im not needing it anymore. Even on low brightness its really clear, but i have good eyes.
I also have my screen to time out in like 15 secs.
about the radio though, i think it depends on your local.
My iphones used to CONSTANTLY search and shift 2g/3g which made my batteries drain like crazy here in CT. this phone doesnt do the switch nor care to search that much.

Must be your locale. I'm sort of in what I thing is a bad luck fringe zone where it searches between 1x and 3g quite a bit. For example I was on the bus today and couldn't stream constantly with Tune In radio cause it would switch to 1x part of the way even though I'm in a solid 3g coverage area.
In the subway where my Treo would hold on to a weak but usable 1x Sprint signal, the NS latches on to Verizon (free roaming anyway) like Succubus. If I set it to Sprint only, then no service.

How does GMail use more battery then display, I mean you can't read&write mails w/o display active.
Here is another tip, underclock your CPU to 800 MHz instead of 1000 MHz. With that setting and JuiceDefender Ultimate, I'm starting at 9am with 95% battery and at midnight I still have 65% battery. (Only 30% loss over 15 hours.) Or about 45 hours on a charge. Of course usage dependent. And my cell signal isn't spectacular either, usually between -105 and -96 dBms.
I'm happy with the balance I have between functionality and battery life. I can go a full day using my phone as I desire with push and sync active all day.

I don't see that. Have you ever overclocked?
I wish folks would stop crowing about juice defender. It's defending nothing by shutting off data and so forth and gimping your phone. I'd rather carry a spare battery and actually use my phone to the best way it suits my needs. My opinion.
No matter what I do the battery will not last me a full day. A full day for me is about 18 hours. I use my phone almost none at all while at work and I use juice defender to keep data and wifi off while I am not using the phone. I would say 80% of my day is wifi and only a little is LTE. I monitor my task usage and the only thing that ever shows up is screen...there are other apps but very little usage. I use auto brightness. Could that be it? Unless JD doesn't work well with these phones, I just can't figure out what it is. Unless of course its just normal...
Phone has to last me 18 hours with moderate usage. If it doesn't, I need another phone.
Post some screenies?

The big killer of battery life is when LTE doesn't have a good signal (inside a large building). Connecting and reconnecting to the tower is what always kills my battery. I suggest you look and try those "turn of LTE" hacks around. My battery lasts me about 20 hours with moderate usage (but I am always in a great LTE location), and about 12 hours with heavy usage.
As long as your signal (wi-fi, LTE, HSPA, whatever it may be) remains good, you should have amazing battery life. I often take my phone out for 16-17 hours between charges and have ended the day with anywhere from 60% to 25% of the battery life, ranging from light to moderate usage.
For me, an average day is on wi-fi for at least 90% of the time, but a recent trip I had to Chicago (LTE all day, no wi-fi) showed similar results - and that was with some more moderate use while traveling! Not sure if there is much you can do about your signal, but I know my last phone (Captivate) got worse signal in my pocket vs. on my desk. SIII doesn't seem to be having as much of an issue, but still something to consider if necessary in your case.
I live in Dallas and have great LTE.
I just copped the sgs3 today and have not put it down my batt isn't that bad. 8 hours st8 on it lol

OP, one suggestion I have...
What makes this phone a winner over my One X is the removable battery. I believe you can get a second stock battery for about $30, and I saw a charger and battery for around $40 earlier. Maybe you should pick up a spare? I realize it's not ideal, but it's an option.

I'm in Vegas, lte rocks and I use my phone constantly. I can't get 4 hours so I just ordered an Anker 2200mAh.
I'm not on wifi but the Lte network in Vegas flies too which is just an additional $$. I've just got juice defender ultimate. I know a lot of people swear by it but I can do it better and faster myself. I'm a heavy user and if we could just turn off the Lte u and then maybe slow down the processor., I would be fine. It's ridiculous we still need additional batteries.
Whenever I leave my house I do the following in settings.
Power Savings I now just leave on.
I either completely Restrict background data or you can do by application in Data usage and go into Accounts and Sync and turn most off. Anything not Google is off and under Google I just sync my calendar, address and Gmail.
Now if we can turn off Lte, I will be fine I think.

I flashed back the complete stock rom and I got great battery life. 12 hours, 3 phone calls, 3 push mail accounts, yahoo checks every 15 minutes, 1 hour streaming and the Windows Weekly podcast and I still had 65% left. I was moving so I didn't get a chance to browse or do work crap on it.

I live/work just outside of an LTE area, and lately have been using my phone pretty light due to not being able to use it at work other than when I'm on lunch. I get almost no signal in my entire building, so 75% of the day I turn airplane on so my battery doesn't get raped.
So for me and my use recently, the battery has been doing good enough for me.
the standby thing raping my battery is weird,same thing with maps even though i never use it... but i guess both are common. Chrome use was at 3% and i forgot to check screen on time.
On the current charge I'm siting at 47% at almost 24 hours, about 1hr 15 mins of screen on time. 30 mins of voice, 10 of chrome...but i accidently unplugged the phone right before i went to sleep last night instead of starting this morning, and i just took a nap so again there is a lot of sleep time
Take all that for what it's worth, which I have no idea lol

I had the same issue, then discovered that going through a charge cycle fixes the issue. I got only 5.5 hours of use off my first charge (80% of the time on standby), but things improved enormously after recharging it to some extent, then unplugging it. See my post http://forum.xda-developers.com/showpost.php?p=28742643&postcount=297
I've had my phone unplugged for an hour now after the last partial charge, and it's actually gone from 48% then to 51% now, as the battery is still recalibrating.

While my battery life is nothing amazing (3hrs of screen time/12 hours full usage) it's not nearly as bad as yours. This is strange. I thought tests indicated that the average battery life was 4 and a half hours of screen on time? I'd love to know if there is a possible battery problem that is causing fluctuation in battery life between phones.

Yes, I seem to be. Usually good with battery management too. Very similar statistics for me. What is your brightness set at?
Sent from my Nexus 4 using xda app-developers app
automatic brightness, this is discharging from an overnight charge, so 100%
Automatic brightness tells people nothing.
Depending on your environment it can range from almost the lowest brightness setting to full if you're out in sunlight
I'm sure the terrible signal isn't helping much. Try switching to 2g when you aren't browsing etc.

My nexus on auto doesn't go as bright as the highest brightness setting. It's about half way or default.
Switching to 2G when I'm at home with wifi coverage helped some. The improvement wasn't dramatic, but it was noticeable.
Are there any apps that will turn off mobile data after a certain period (say 15 minutes?) to save battery life? That is the only thing that I can figure is killing my phone so much more quickly. I have unlimited data and no wifi at home, so I leave it on at all times. My old phone, however, had a setting that would turn it off after the screen had been shut down for 15 minutes (and turn it on occasionally to sync).
I don't want to have to toggle my data on and off all the time to make the phone last more than 7 hours.

Unfortunately, I don't have any tips. I have the same usage (though mine was all on HSPA, no WiFi) in a fairly bright room with auto brightness and nearly identical battery life. My Galaxy Nexus under the same usage conditions would get significantly better (3-4 hours of screen on time instead of 2).

Hey, I am still getting similar statistics to you. I turned off Google now last night and set the brightness to just over quarter (in case it was the auto brightness that was the problem).
Still getting terrible numbers compared to others, it seems that those of us getting bad batt life have very similar numbers in terms of time off charger and screen-on time.

I have had greatly improved speed and battery with Code fire X BR2 ( haven't tried BR4) and Matrix 2.0 kernel. Also I set my cell radio to GSM auto PRL which prevents the phone from constantly searching for 3g if signal isn't strong enough (or something like that) but helps. I also left the screen setting on auto brightness.

3hrs 30min screen time.
Running 4.2.1 rooted with the Matrix 2.0 kernel and gov set to interactive. No other tweaks or anything special done to try and increase battery life. 2 mailboxes using push mail and on Wi-Fi for the better party of the day.
I would check using CPU Spy and Better Battery Stats just to make sure your phone is getting in to deep sleep, and nothing is holding the device awake.

Auto Data is much more lightweight and has less settings to get lost in than Juice Defender. You can set it to turn data off immediately or after fifteen minutes

For some reason I think the numerous stock google apps spend a lot of time phoning home. I disabled seversl of them that I don't use in the app settings (G+, Currents, Magazines). That changed seemed to help and it's easy to try.
I recently got a razr HD and i noticed my battery barely lasts a day. I had a flip phone before and it would last a week on one charge, i know i wont get the same type of battery life. I downloaded juice defender and set it to turn off my wifi/data when not in use. It has helped a bit since before that my phone would lose 2% battery an hour just in standby. I haven't downloaded any task killers, but when i'm done with my apps i go in to the settings and close them.

Two things to fix,
one, adjust your brightness to auto. The higher the brightness, the faster your battery dies, that is massive screen use.
two, poor wifi/cellular reception = ****ty battery, the phone uses more power to lock onto signal.
Dont use task killers, they do more harm than good.
I adjusted the brightness on my tbolt and I doubled battery life

Hmmmm. i wasn't very through with my post, but i have mine set on auto brightness. My wifi at home is usually 4 bars and 3 if im in the basement. I get 4 bars LTE for 95% of my day. In the main building on campus i get 1 bar if im lucky but usually its out of service so i depend on the wifi. The only thing i use my phone for is listening to music on my way to school, texting, email (but i set it to sync every hour), some light internet browsing, and calls.
Edit: Also on a sidenote is the smart actions useful? It seems like it does the same thing like juice defender.

yes, smart actions does the same thing with less battery,
UP your sync time! The more often you sync the more battery you use! I would put it on 4 hours and only sync if you need something important.
Turn of your cellular radios at school and that will help battery
Clearly your screen is consuming most of the battery. Try lowering your brightness, If you used it to text and kept the screen on for long time.. it might have consumed battery in that period. Not sure if its helpful or not .. but here are my battery stats after a normal usage day.

The 3 hours in sync shouldn't be eating up my battery though, but i guess every bit helps.

nah, just change the sync settings to longer and set your brightness to auto and see what happens over the next few days and report back.
I noticed the biggest difference when turning off WiFi and mobile locations.
Also 4.1.2 seemed to increase my battery life dramatically too.
I don't think setting the brightness to Auto is the best for saving battery. When in auto, the light sensor is turned on and some processing has to be done to define the brightness every time the screen is turned on. And that consumes energy.
I always keep mine at 50% and, when in very bright places, I go for 100% brightness.
Hi again, today i disabled my wifi and data manually whenever i wasn't using them and manually enabled it whenever i needed it. It worked a lot better and i left my house with 85% charge and i used my phone a little bit more than yesterday and it used up a little bit over 25%. I also played around with my juicedefender settings and hopefully it will work better. I will set my brightness to 50%. I'll post back in a few days. And is my battery working properly, because i honestly expected it to last a lot longer. Also thanks for the suggestions.
I really like 2x battery for controlling battery usage by data connections. There a light version as well. It basically turns off mobile data when the screen is off and turns it on when the screen is turned on. It can do the same for wifi as well. The light version will reconnect and sync everything every 15 minutes (or you can turn sync off). I paid for the full version and it allows you to change the sync time to longer increments. I use it mostly because I don't want to have to remember to toggle and where I work the 4G signal isn't so great.

Have the same problem! Brightness is low, internet is off, when I don't need it, still the battery is weak!
You said you had a flip phone before and the battery lasted a week, is this your first smartphone?
Smartphones have a 24 hour battery life at best, This phone has an above average battery I have had 48 hrs out of it..
other things to get in mind is the ROM you are using, I see you are on stock Ice Cream Sandwich, ICS have a good battery life, I have tried Telstra Jellybean and it was not as good, I also get excellent battery life with epinter's CM10
I am very satisfied with the battery life! I also recommend x2 battery, which seems to prolong battery life with little to no impact on the usability of the phone (at most a potential short delay on emails when not on wifi). I generally use wifi whenever possible which use much less battery than the mobile modem. Also I have disabled a few stock apps that I don't use e.g. the non-gmail (stock) email app. The phone is not rooted and using stock o2 JB rom.

Also have a look using Better Battery Stats app to see what your most battery hungry wakelocks are, especially Kernel wakelocks.
I had issue when I first got my razr as I was using it on a network that doesn't have Fast Dormancy yet the phone has fast dormancy enabled, so i had to freeze it and battery life improved a little.
But unfortunately fo me the main problem was where i live. I'm in a city, so it's not a lack of cell towers, but for some reason at home my battery usage is insane while connected to mobile data, 9%-11% an hour with no use compared to 2%-5% elsewhere around the city. (Am thinking it must be getting bounced from tower t tower trying to get a better H+ connection) As soon as I switch over to wi-fi tho (which I have set to always on,) my battery usage drops to about 0.8%-1.2% per hour in standby.
