Mine has been terrible for awhile. Even Odin back to stock and it wasn't any better. Now I'm on a clean flash with very little installed and I've only seen minimal improvement.
Here are a couple of screenshots from this morning looking at while I was sleeping. Lost 25% overnight. Had an hour of awake time with near zero screen time, seems like a lot of battery lost
You're letting way too many apps sync in the background, your phone is not reaching deep sleep. I bet you left your Google account on auto sync. Your email is syncing too often. don't leave wifi on overnight. You're getting poor signal too.

25% loss is not bad at all. I've had 68% loss complain about that lol

I've always let my Google account sync and left wifi on at night. It just seems like the last month or so it's chewed up lots of battery. Heck with my old desire it'd only use 3-4% (with basically the same setup) overnight.
I had this problem and was able to fix it by repeatedly throwing my battery on the sidewalk. It helps to re-excite the electrons in the battery and improve battery life.
I am trolling, in all seriousness, lithium ion batteries significantly reduce in capacity over time. It is perfectly normal for the battery to last 25 to 50 percent less long just a year in. Pro-tip, you can find replacement stock batteries on Amazon for about $10, just make sure it is an OEM battery. If you are nice to the tech or store manager at your local sprint corporate store, sometimes they will give you a replacement battery for free.

Thanks. I'm with us cellular and the phone is only two months old. They do have a battery swap benefit, but I think it can a crap shoot on the quality you get back.
I un installed that hacked s-voice app, that seemed to help quite a bit.
So it must be something with wifi. Had wifi off all day yesterday at home and last night (just using 3g connection) and I only lost 2% overnight. On 16 hours with an hour of screen time and still at 79%. Not seeing the wake ups and wakelocks like I was before.

Sounds like you've got apps set to sync when on Wifi only then. To confirm, try leaving Wifi on but turning off background data. If your battery life improves, it's definitely an app. Then you just have to go through your apps and figure out which one it is.
Gmail can be set to push so you don't have to worry about it syncing unless necessary. But if you get a ton of emails, it's still going to hurt.
Also, I disagree with revamper, if you get poor signal you should leaving Wifi on as much as possible. Being connected to solid Wifi will drain less battery than your phone constantly polling towers for a better signal (given identical app behavior, which you don't have atm). I'd still turn Wifi off when moving about, as you won't be on a single, solid Wifi connection and you phone will be polling both towers and Wifi networks, resulting in increased battery drain. You also want to set Wifi Sleep Policy to not sleep when the phone screen is off (otherwise as soon as you turn off the screen Wifi is disabled and you're polling towers again). From what you've said, it sounds like this is already set though.
The best thing I've ever done for my battery life was flash Calkulin's ICS ROM. 4 days of standby or a full day of some really heavy use. Email is the only thing that syncs automatically (push). Other apps like Facebook aren't that important to me so they only sync when I open them.

I had a battery cook in the phone this weekend and this is what the sprint tech did. I picked up my phone after being on the charger overnight and it was almost hot enough to burn me. I took it in, they popped it out and spun it like a top... Handed me a new battery within 5 minutes.
Yeah it's probably wifi. I also have much higher idle drain on wifi than 3G right now, although I haven't had time diagnose it. Actually, I hadn't bothered because I was planning to move to an AOSP ROM from stock ICS once kernel source was published, but I'm losing my patience. The AOSP guys seem to have things worked out without source anyways.

I also have extremely high drain while on wifi, I just made it so the wifi shuts off when the screen shuts off
I haven't seen a battery life thread for the AT&T S3, so I'll start one.
Mine is around 13 hours with moderate use. I listen to podcasts for an hour in the morning (commute to work), read Pulse News and Facebook for about an hour at lunch, and listen to another hour of podcasts for the commute back home. By the time I get home, I'm around 13% life. I usually get the battery warning while listening to my podcast. In comparison, my GNex GSM gets 17 hours with the same use pattern. When I get home, I'm usually around 37%. Besides Samsung's and AT&T's bloatware, same apps, no widgets.
All told, I am very disappointed with battery life. I don't believe in underclocking my CPU in or disabling haptic feedback. I use the "Power Saver" mode, but only use the reduced screen power consumption feature (reduces framerates and brightness). WFI is always off (I don't have WIFI at work). I also disabled all of the Motion features. I disabled S-Voice (it monitors for the Hi Galaxy, and disabling also allows for a very responsive Home button).
I calculated my idle battery drain (unplugged when fully charged and not touch it) at around 4.4% per hour. That only gives 22.7 hours of standby! My Galaxy Nexus GSM can go at least 2 days (sometimes I forget to charge it at night on the weekends - also not used the phone).
Is it AT&T's LTE? Is it the Gsiff_daemon process? Is it TouchWiz? Or is it just my phone?
What's your battery life like?
You pretty much hit it right on the head. I had the extended battery from Samsung on my Gnex and could easily get 20 hours with moderate usage.
This phone despite using CM10 or AOKP with the JB kernel I never see battery life that good. I'm in the 14-15 hour range with about 3 hours of screen on time. That's with wifi off, and we don't have LTE yet. All in all, it isn't very good.

Stock? What features do you have turned off? Do you use WIFI exclusively? Do you turn off your data network (LTE/HSPA)? Did you turn off Sync?
I don't use WIFI, and I leave my data on (as it should be - just like I had it on my GNex). I also leave sync on. I understand that using these decrease battery life, but come on... not like this. The GNex faired very well, and it had a smaller battery. Besides LTE and an S4 (and the S4 should be more power efficient), there isn't much different between the GNex and the S3.
If I turn on the screen for 8 hours, there won't be enough for sleep time! It'll just die... if it even makes it to 8 hours...
20+ hrs with multiple accounts syncing at 1 to 2hr intervals, screen on time of average 4hrs. Heavy use. Wifi on all the time.
stock, rooted, debloated, super-aggressive power management I was getting maybe 12 hours with 2 hours screen time.
I saw you didn't believe in underclocking, but I started using Cpu Editor http://forum.xda-developers.com/showthread.php?t=1798765 and am loving it, can do 16 hours and 4 hours of screen time with no problems, will do the trick for me.

my battery drains a lot when i'm on wifi even when my screen isn't on. I get on average 14 hours running 1.4 GHz
You have a faulty radio.
I consistently get 40+ hours off charger with 4-5 hours screen on time with a couple hours of browsing, 3-4 hours of music, texts, an hour of calls or so, playing casual games for another hour.
Stock. No hacks. No root. Disabled all unnecessary carrier and samsung apps and disabled GPS unless i need it. Auto brightness, 2 hours sync for weathereye, flipboard and gmail syncing all the time. I do mostly use Wifi at home because my signal at home is bad and that quickly drains my battery. At work my phone idles for eight hours at a 2-3 % loss with 3G on (i use my old SIM, i do not have an LTE plan, I am on Rogers Wireless).

You consistently (or have ever got) get 40+ hours off charger with 4 to 5 hours of screen time? Do you have your phone hooked up to a car battery?
I just factory reset (wiped data and cache) the phone and installed the apps I need (maybe something was badly configured or something) - did that yesterday night. Charged it up for this morning, and now I got 18 hours and still have 17% left. Screen on time says 1:38 hours.
This is on the same stock rooted and deodexed ROM. No hotboots either, so gsiff_daemon didn't rear it's ugly head.
Also no CPU Sleeper or any of these underclocking apps. I'm happy now, but wondering wtf was causing the problem... and will it happen again (after all, this is only day one).
I'm getting about 13 hours with 5 and a half hours of screen time. Underclocked to 1.2ghz and I have my own screen off profile. Great battery in my opinion

Phone finally died. Just over 19 hours. Heavy use towards the end because I was downloading and installing the rest of my apps from Google Play & Amazon App Store. Was also setting the apps up ( accounts, settings, and notifications...). Final screen on time was about 2 hours.
It's only been two days since I've had the phone, I've gotten about 14 hrs with roughly 3.5 hrs screen on time. I hate when I see people with 2 days off the charger and ridiculous screen on time. If you put the phone in airplane mode and ran just the screen you probably wouldn't last 10 hrs unless it was on low brightness. I had the Razor Maxx and I could get around 30 hrs usage with 4-5 hrs talk and 6 hrs screen on and that's the best battery life I've ever gotten on any phone with real usage.
I would like to get better stand by and more screen time out of this phone without getting an extended battery.

No airplane mode. Cellular connection is always on even during the night. Only difference is at home i have wifi on instead of data.
Flipboard, weathereye and an appsales app syncing every 4 hours. Auto sync for google account and facebook. Automatic brightness. Almost all samsung and Rogers apps disabled (except for myaccount and a couple samsung apps) and motion disabled since i have no use for the gestures apart from being a novelty the first week.
No root. No hacks. I am actually amazed. This is the first android phone that has battery life on par with my iPhone 4 and the unparalleled smoothness. My HTC One X lagged, this never does even with a few apps installed now including games. I look at my iPhone and think "why do i still keep it? It is no longer relevant".
Ive got my UV tweaked just right on my ktoonez kernel and keeping my screen level as low as can be and I'm now practically making it to TWO days battery life! Plug in every second afternoon or evening after moderate use. Occasionally it doesn't last as long. Quite happy now. Oh and that's with this baby cranked to 1.809Ghz! But obviously tweaked to use that under strain otherwise using lower clocks and deep sleeping with 384mhz.
Got a 4200mah extended battery on way and can't wait to see how much I can squeeze out of it too.

My GS3 i747m lasts around 50-55 hours per charge cycle..
It is running stock Rogers GS3 ICS, not rooted, all stock. Battery is stock as well.
Not using LTE, using HSPA+ ("4G") with data turned ON with Sync turned OFF
(**NOTE: sometimes, the battery is drained due to poor reception, and the phone will use more power for the cellular signal.. In my case, my 3G connection in my area seems alright for the most part, about 1 bar less from full)
Power saving is turned ON. WiFi powersave is turned ON.
Moderated WiFi usage in 2.4ghz 802.11g-mode only.
Every night when I go to sleep, my flight mode is turned ON. (I sleep around 9-10 hours everyday, so the phone stays on flight mode for 9-10 hours a day)
In the morning, I turn the flight mode OFF.
Bluetooth, GPS both are turned OFF
Screen brightness turned 1/4 brightness
LED notification turned OFF
Also, I have a task killer killing ALL BACKGROUND SERVICES every half hour.
Without killing all the background apps, my RAM usage is around 600-700 MB out of 1.6 GB of RAM
Killing all the background apps brings the RAM usage to around 360 MB of 1.6 GB
Without killing background apps, my battery life is shortened even when the phone is on standby.
Do this, and your battery life is pretty good..
I noticed my battery life is terrible. My phone is only like 5 weeks old. I've tried the battery saver apps, power-saving, and pretty much every other tip. I start off with 100% in the morning with brightness turned down and everything else and I mainly listen to music more than anything so the screen is usually turned off. It still manages to go from 100% at 7:30 to about 17% at about 4:30. And the phone is turned off for about 3 of those hours. Also the other day I started playing TDKRw/100% battery life at 7:30 on high brightness and power saving was off. At 10:00 the battery life was at 15% not to mention I paused the game a lot. Is this normal at all?
Seems ODD. My phone is like that as well but one thing that i noticed is turning off cellphone data. that helps battery life big time. try that and see how it goes.
The TDKR, would be normal, the high end games just gobble up power, often even consuming more power then a charger can keep up with.

I was like that when I bought my phone, but after playing around with some ROMs and kernels, I found what's working for me - ParanoidAndroid + Ktoonsez kernel = 2 days moderate use and over 5 hours screen time with 100mV undervolt
OP might have bad reception too, that'll eat your battery up
Reception is a killer battery eater.
Especially for me, just moderate texting and some short phone calls will drain my battery.
It's because where I live, the signals are fairly weak and I will get EDGE or 3G data most of the time.
Additionally, check your wakelocks. Sometimes applications run during when the phone is supposed to be asleep. Getting a handy battery measuring app will help.
Also try turning off sync or turning your settings for e-mail, google services, etc. to manual so they won't run when you're not using the device.
Otherwise, the forums probably have dozens of posts with tips on increasing your battery life.
There are many battery threads, true. But as of a day or two ago, you only need one!
Woodrube ported his thread over for us. I highly recommend evrryone take a few min to read it!
http://forum.xda-developers.com/showthread.php?t=1969741
For those of you with poor signal and wind up on Edge, turn on wifi if possible. It uses less power than your data connection, plus, by having it on it disables mobile data leaving only the voice connection which is much easier to get a strong signal for. So in every way this could help with battery savings.
Even if you have a great signal, your wifi will still use less power. I always connect to eofi when I'm able and the sleep policy is set to always stay connected. If you set it to disable while asleep it simply will activate mobile data in its place.

Sorry for the slow response. Haven't had time to get on here. Thanks for all the help though. I was mainly scared though because I heard some of the phones had a bug in them to where it drains the battery life like crazy. I think that woodrube thread will help me tremendously.

The only thing about that is, I barely make phone calls or text at all. Like I might text 3 times day and make calls like 3 times a week.

I use TTPOD to listen to music,its free for the full edition and has great equalizer....
I hate to be the guy that asks this, but I just want to make sure as from what I understand this is different from phone to phone. From what I understand, Li-Ion batteries, like the GN2's, do not have a memory effect of any kind? And thus all battery calibration rituals and nonsense are entirely pointless for this handset?
The reason I ask is because I wasn't able to charge the device to 100% before use like I was always told to do with new phones. My device was turned on and used until it drained to around 10% at which point it was charged to 100%.
Now, after 2 weeks of use, I feel that my battery is not as good as it should be. I'm barely able to get more that 12 hours. I'd be happy to post some battery graphs in the morning.
One last thing, if I did mess up my battery, or if my battery is messed up or less functional than it should be, would buying a new battery fix all my problems?
Youvare right. All that calibration stuff is nonsense.
I have never charged my phone to full before using and draining the battery and my phone still lasts all day on mostly heavy use.
Could you post your batt stats?

Today I ran my phone with the "lowest" possible settings, that is lowest brightness, CPU power saving, and no haptic feedback. I did not turn off wifi. Doing this I was able to get a surprising 16 hours, although you can see from the graph that I didn't use my phone as much. Attached I have a screenshot of what it's like with the highest possible settings (no power saving stuff, and brightness all the way up, but no GPS). Sorry I don't have a pic of the percentages for the high settings, I never thought to do that.
What concerns me the most is this: even with the lowest settings, I'm only getting 2 hours screen time. (last pic)
What's interesting is that you would think that if I'm getting such poor screen time, there would be something else using a lot of battery, but there isn't. This led me to believe the problem was with the battery. I discovered a pretty big scratch on my screen the other day, and I have some monthly insurance plan from best buy, so I was thinking of just getting a new one. The longer I wait to get a new one, the harder it will be to set up everything again. lol
I noticed that compared to other GN2s, mine seems to wake up a lot when the screen isn't on. The awake periods tend to correspond with drops in battery and also when I have a poor signal. Could this be caused by my phone trying to look for signal and using battery?
Yes poor signal that results in the phone searching for better 3g/2g will drain the batteey faster.
Can you try using it in airplane mode with wifi only for a day and see how that goes?
Also install Better Battery Stats and after a day or so of normal usage check your partial unlocks to see if a rogue app is preventing deep sleep and sucking your juice.

K, I agree with my week signal using battery. I only have 75 apps on my phone and they're all pretty mainstream, no obscure apps. Right now im in school with 86% battery, I'm turning on airplane mode now. I have noticed however that when I clear my ram it closes like 50-60 processes each time. I am always closing my apps, but 50 seems extremely high. im gonna turn on airplane mode and see how that goes...
thanks!
Yes, you do have poor signal but that's not all. You have terrible wakelocks pal. Install BBS and monitor which apps are the culprit. It's not about 75 apps, even 2 or 3 bad apps, which have hidden advertisement going on could suck your battery flat in no time.
So first thing, install BBS. 2h screen on time is horrible!
Btw- If you're on 3G, try to switch to 2G. Difference will be unthinkable.

Thanks everyone! I'm really loaded with school work, so I don't have a lot of time right now. But long story short, airplane mode saves my battery like crazy. I started school with 86%, turned on airplane mode, and I'm at 79% right now! more later
Is it safe to say I fixed it?
3h screen over 2 days isnt bad right? Perhaps just a bit worse than what others are getting?

Hello guys.
I've been reading these forums for a few months now and find it very very helpful in configuring my device. It's just now that i decided to sign up so i can be part of this great community.
This is my first ever post and i would like to get help regarding my battery life.
Ive read a few articles about battery saving and also from forums where people usually get more than a day's worth of battery life. That got me wondering why i only get around 8-10 hours average considering i only use it very lightly as im usually busy at the office. My actual usage time range about 60% of those 10 hours when i use the phone during breaks.
Here are example screenshots of my daily usage:
Here are some details about my configuration:
Brightness set to auto, most of the time at 75% level
Wifi, bluetooth, gps always off
Haptic feedback set to minimum
Mobile data always on and set to WCDMA only, area where im at is usually weak peaking at 2 bars of H and H+ signal strength
Gmail set to push notify
A few apps and widgets set to sync after every few hours(accuweather, flipboard)
Ive been considering getting an extra battery because of this but i really want to make sure first whether i could still do something or whether im doin something wrong thateads to the battery draining too fast.
So please if you have any more tips i could use, please help me out on this.
I thank you in advance.

Their battery lasts whole day long. It means that they get 10 hours of screen on time only. Not 24 hours.
Sent from my GT-N7100
Yeah. But in my case the 10 hours is the total life of the battery from the time it is charged until it dies. I'd be lucky if i even get 4 hours screen time out of it.
Do you have an idea why this is so?
Im guessing its because of the weak signal where im at and the fact that i set my phone to search for WCDMA only. Although im not sure whether this is really the culprit. I'll try setting the network mode to auto for now and see if anything changes.

Looks like it.
Try better battery status.
Sent from my GT-N7100
Well after i changed it to auto it improved a bit. Its currently at 14% after 11 1/2 hours with 4 1/2 hours of screen on time. The phone stayed on full edge signal for most of the time (which kind of sucks because internet became painfully slow on edge).
But still, i think this is far too short when compared to those who can get it to more than 24 hours battery and more than 10 hours of screen on time.
Is it possible that i have a defective battery?

i got exactly the same problem, whats your firmware?
since i updated the phone to 4.1.2 the battery drains alone, every 8 hours it discharges 25% without using the phone, i am lucky if i get 5 hours of screen. The android os is the one draining all the battery in my phone. On 4.1.1 i could get 7 hours of screen time with 20+hours overall.

i got 4.1.2.
I can't compare mine to 4.1.1 because when i bought mine it got updated to 4.1.2 after a few hours.
having to charge at least two times a day really negates the otherwise great features of this phone.
I really hope we figure this out. I'll try UtkarshGuptas suggestion using Better Battery Stats and let you know what i find out.
I did they and found Google location services is the culprit.
I'm am referring to the locations services found under location setting in the actual Google maps app. I believe turning of location reporting may disrupt Google now features. Google locations devices is reading out as the main reason for nine consistent partial wake locks on better battery stats.
I'll try turning these features off and awe how it affects battery life and Google now tomorrow.

I'll try turning these features off and awe how it affects battery life and Google now tomorrow.

Please let us know.
after doin some tests with bbs i found the wakelock is mhl_wakelock,
First off, forget all the battery programs. Factory default your phone and add an apk at a time and use. You'll be able to tell what apk is the problem with a lil testing. Slow process yes but pretty straight forward and to the point. I do have a Note 2 and have no battery issues being rooted and having tons of programs, etc. Basically, I use and abuse my device as per my job and still get a day and a half out of the battery.
People who can get 24hr coupled with 8hr screen time most likely have their phone on low brightness and on WIFI not data.
I got a new battery and its still lasts the same as the other. Yeah it may be because of the mobile data always on that eats up my battery.
Problem is my data connection is my primary internet source i dont always have wifi hotspots. So i might just have to live with the short battery life or learn to turn off my data when i dont need it.
I'll still try looking for other things that contribute to the battery being drained though.
Thanks everyone.

I have GPS disabled, auto brightness (but fairly high level) and that improved battery life quite a bit. I then changed kernel to NEAK kernel, reduced the voltage levels for the CPU and that further improved battery life. I can get a full 24 hours on one charge and with normal (?) usage). With the new kernel I can also modify the charging current to a slightly higher level which reduces the time to bring to a full charge.
All in all not too bad but to expect more than 24 hours is unrealistic in my opinion as it is a big handful of electronics!
Not sure what you guys are are doing different. This is my first full month with my note and the battery is a beast. GPS is enabled at all times but all other syncs are disabled. That's just from previous experience. Sync will always drain the battery. So mine is off. I went as far as removing all the extra chargers around my office and home. .now I only need one. And I alsi don't see a need for an extended battery unless I'm going to be away from civilization for a few days. By the way..that was the only time I've killed my battery..kinda. see screenies
--I forgot about brightness- mine is set to 50% and 4G/LTE ..if the device is always searching for it, it will kill your battery. I turn it off at the office as much as I can.

I get between 6-7 hours of on screen time on mine.
Using dark backgrounds really helped the bettery life for me. I use a dark wallpaper for touchwiz, whatsapp, and also carbon as my twitter client.
Using Perseus kernel also helped because it doesn't ramp up the cpu as high as the stock kernel.
Wanamlite rom.
Brightness set to lowest at home. 25-50% when outdoors.
Two MS exchange emails set to push.
I use wifi all the time unless it's not available I switch to HSPA+. what a waste of a paid data plan
Google now disabled because it's a battery hog. location services kept on though.
