Stop using the light and orientation sensors. So turn off auto-rotate and don't use auto-screen brightness. Also use wifi when possible; 3g will consume more power if your signal is weak.

It is not good for me either. I am loosing about 15% a hour with the screen off and not even using it. If I use the phone i can just watch it fall about 1% every 5 min. I don't get it. the only thing i have in the background running is weather, twitter and gmail. That is it nothing else. The Android OS sits about 86% use in the batter use screen. I have no idea what is causing this. Any help would be great.

Run the phone down completely, to the point where it shuts off. Then charge until the led turns blue(fully charged), then turn it on. I'll screenshot my battery status tonight.

Yes it is always posted that high. I have also already tried the suggestion of completely draining the battery and charging to 100% twice now. Doesn't seem to help. This is not my first android phone so I have tried all the typical turn stuff off. I started with the hero and then went to the evo. Then jumped to verizon for thunderbold and now back on sprint for this phone obviously. So far this is the worst battery life I have had yet. Seeing what you guys are getting though gives me hope.
I have tried using spareparts to get more battery information but get a force close when trying to do that.
Man I know that battery results range pretty wildly, but I'm averaging 10% loss per 2 hours.
On launch day I was on it from about 3:30pm until about 10pm and only lost about 40%. And when I say on it, I bet the screen on time was 95% of that time.
So far, the battery life is one of my favorite things about this phone. First time I've felt comfortable enough to run a live wallpaper.

You are lucky then, If i use the phone I will loose 40% in about 2 hours no problem. Also if you are loosing about 5% an hour that will only give you about 20 hours total before your dead. I see people reporting they are getting over a day. Just don't see how. Are they just not using their phone at all.
What does everyone have there screen brightness to if not set to auto brightness? Also what is everyone's screen mode set to?

I have mine at manual and just under the A. I have the mode at standard.
What I do is look at my active app widget to make sure I have no apps running. It is nice being there. Messaging sometimes hangs, I have noticed that.

You SHOULD always when you get a new battery fully Drain it and then fully charge the battery with the device OFF. Thats what I did with my phone. I kept using it once I got it, it lasted around 5 hours before the phone shut off during a phone call. then when I plugged it in to charge, I plugged it in and did not turn it on and waited till it fully charged with the Blue Light. I dont know about the normal thing now adays with lithium ion batteries but you were always warned in the packaging to let your battery fully cyle its first cycle with no use at all. The cells in the batteries have a memory type of design and if you dont fully charge the battery you can prevent it from knowing its full capacity.
Now I dont know if this is true anymore with the new battery production of the manufacturers now may power cycle the batteries before they seal the whole package so the customers dont have to do it. Maybe why when you get your device the battery is around 50% now like mine came. I remember older devices you could not use your device until you fully charged the battery the first time.
About Screen Brightness, I learned from a Epic user that the best way to conserve battry usage was to always keep your Screen Brightness at 10% (Gotta love the Touchwiz Brightness Changing with the Top Notification bar, this device will not show the slider bar like Touchwiz 3.0 on the Epic but IT STILL WORKS!!!!). I have noticed that at the lowest brightness setting I can still see everything vividly enough to work with it and im getting over 24 hours with moderate normal usage (like only 1-3 5-10 minute phone calls, surfing the net, surfing for new apps) This is my first android phone. I also have had 4G turned off and Wifi off all this time as I have no way to access those right now. I also have GPS turned off because I havent needed to use it yet. I pretty much have everything but Basic needs turned on besides all the Factory default presets. I also Turned my screen mode to DYNAMIC, which seems to show more vivid colors like I use on my Samsung TV for my computer usage.
Now I turned off Live wallpaper and im using one of the preinstall basic Grey ones (the one with the asfault looking spot light) (I have been trying to hit the crazy benchmarks people are getting trying to find out why I am not getting the 93+mflops mine keeps hitting 80's) So I dont know what heavy usage is doing to my phone.
but then again this is only under 48 hours of ownage. My first full night off the charger was 1 day and 3hours before it said I was 5% battery life and I plugged it in.
-Wifi and Bluetooth on whole time
- Tons of texting, a lot
- Over 1 hour of phone calls on Bluetooth
- Over 3 hours of A2DP streaming
- Periods of no signal (subway)
- Screen on for 2 hours
- Google Reader and Web browsing
- Used the phone as I would normally without thinking about battery at all.
Very very happy. UPDATED with recent screenshots before I plugged it in.

Out of interest, how many times have you charged your phone (0%-100%)?
Never drained it to zero and started using it right away without charging it. Its been charged to 100 twice already. My uptime is 73 hours and that's exactly how long I've had the phone.

Wow! I wish mine was as good as that, seems to be getting better with each charge though, which is a positive.

Honest question, how many times are you more than 12 hours from sleeping or relaxing in your house?
12 hours is more than adequate for a normal user
This is mine after a fresh wipe and no apps installed. Just thought i`d see how it did with normal use.
Here's mine; at a point the phone got itself shut down for some reason, and I couldnt get it restarted at that moment, so I left it like that, and when I could turn it back on, it was quite warm around the camera unit, and also the battery was pretty much drained - thats what you can also see on the screenshot at the "20minutes" part of t he scale. After I've removed the battery and put it back, the phone was working for quite a while again, like 12 more hours.
I'm sure auto brightness helps as it keeps screen dim but during my use it was brighter especially outdoors. My whole point is there is no secret, you should use the phone as you would like it. One thing I could have done I'm sure to improve battery life is turn off wifi and bt when they weren't in use and possibly not have as many apps running but then what's the point in having the phone?: D

I get around 11-13 hours. Not too impressed. My iPhone 4S gets 20 easily. I'm really conservative on my Nexus too because doing anything intensive (games, video recording, youtube etc) really rapes the battery. I'm guessing some of you turn off auto sync or something.

I'm currently on 1 day 1 hour, with 50% left. Although with light usage.

I was able to do that last night but honestly not a big deal plugging it in.
It's simple really - the more you use the phone the worse battery life is but that's because you used the phone more! I never use the phone LESS just for battery life because then you're doing yourself and the phone injustice.
43% - 14h.. screen taking up 48%
from what I can see, apart from the screen, the biggest battery hog is wifi/3g
I installed Juice Defender and I am getting fantastic battery life now:

So JuiceDefender works fine for you? I just read that alot of users had problems with ICS and JD. Would be great if it worked though!
Here's mine. Since I was at work all day I only got time to play Dillo Hills for about 20 mins but I've found the battery is REALLY good after flashing the Android Revolution ROM. MoDaCo causes too much drain IMHO.
Battery life isn't too bad on mine. I got mine on the 10th and I used it right out of the box. Battery life wasn't that great until I did a charge to 100%. The OTA update didn't change much for me in regards to battery. Currently at 21h uptime and I'm at 32%.
I bought a used Galaxy S3 just a few days ago and have had pretty crappy battery life, or at least crappy when compared to what I read in some reviews. This guy claims that a 90 minute video with sync going on in background drained the battery to only 82%. I'm seeing much worse numbers. Leaving the screen on for one hour drained the battery to 75%. Other than occasionally touching the screen, I didn't use the phone for anything else during this time. Screen brightness was set to about 60% and wifi was off. The phone is rooted but still on stock UVLH2. Screenshots of the battery usage screen are attached. Does it sound like I have a bad battery?
Most people are getting about 5 hours of screen on time per battery charge.
At that rate you get 4 hours thats what I average with 2 different batteries.

But I'm not using the device for anything. There is nothing running. You can see in the screenshot that the only two things using the battery are the screen and the system process, which is at 2%. Is the number cited in the review I linked to in the original post simply BS?

I don't understand what you are trying to say. I left the screen on as a mean of draining the battery that can be easily and consistently reproduced. Browsing the web, playing a video, or running some app introduces additional variables that I can't easily control for. If, as dkmlb says, most people are getting about 5 hours of screen time while also using the phone (browsing the web, playing a game, etc.) and I'm getting only 4hrs while not using power for anything but the screen, then there is possibly something wrong with my battery.
you need to use the phone more for the battery to adjust itself. I set the brightness at 50, wifi on (when outside, 4G on), GPS on. My daily usage includes checking email, reading news on Pulse, check google play,etc yesterday the total screen time on was 3 hours. All of that last over a day (24h) and I still had 10%. (I dont play video, music, games, etc..)
What you said was true I didn't even think about it, but give it a couple days and cycle the battery normally (don't let it go past 3% with out plugging it in) and use it as a daily use and see if its good for you.

Background: Rooted, stock rom.
- Just bought the phone on Saturday, charged it fully and played around with it on Sunday literally just moderate texting, making short calls, and taking a couple of pictures and the battery pretty much dies by 2 PM. Will the battery life improve over time?
This is with the settings tweaked to maximum battery conservation (15% screen brightness, NFC/S Beam off, No motion controls, battery savings on, the works.)
- Also, in that time the phone seemed to be fairly hot, I cannot recall the temperature, but it was hot to the touch. And when I tried downloading the OTA update from T-mobile, the bottom half of the phone (everything below the battery) became drastically hot. But the battery remained relatively cool. Is this something I should worry about?
I'd just like to know so I can exchange the phone while I still can.
I just got mine on Friday and I noticed the same issue. It seems to get hot whenever its doing something data intensive live streaming a youtube vid or downloading a app.
Thanks for the response.
I used it for about 15 minutes this morning reading a web page on Chrome and it seemed to get warm.
Also streamed HD YouTube as well as Spotify for about 15 minutes and it's still warm.
The thing is, these are the first really data-intensive things that I have done so far.
I'm going to go through a whole day just to see what happens.
Forgot to add that I even reduced my CPU through SetCPU to 1.2Ghz the since I rooted it
It's at 87% after 2h 20m 46s on battery.
With only 42m 23s of screen time.
It should calm down after a couple of charge cycles. For battery. Also make sure auto brightness, auto sync is off, gps, motIon control, voIce cmd, etc.
I dont use the battery saving feature and get great life. But I remember a few times it getting hot after a fresh flash but it always calmed down for me. Getting warm is normal, especially if on the charger while using.
Theres a lot of features I like but dont use much so for me its worth the few extra seconds to turn it on/off.

Update
So I have completed my school day.
11h 25m 45s on battery
Battery percentage is at 57%.
I barely used the phone however.
Sent about 10 texts, went on Chrome and searched the web for about 15 minutes, took 8 pictures, instagram for 3 minutes.
Also kept getting e-mails (probably like 10 of them)
I turned on Power Saving mode as well.
Screen is the highest with 1h 32m 24s using 38% on my battery.
Would this be normal on the stock T-mobile rom with no updates?
I've never had an Android phone before so I wouldn't know.
But after researching, some people managed to be at around 70% usage by the end of the day. While doing more intensive tasks.
It's probably the service when you're inside buildings. If it's bad service it'll drain your battery.. if it's constantly trying to connect 4g you're going to have a short time *insert ski instructor meme*

At home, I literally get 0-2 bars. But at school I can consistently get anywhere from 1-4 bars.
This could possibly be it, but I am not too sure how much my signal fluctuates throughout the school.

I had given my local T-mobile store a call and they said that smartphones should be regularly heating.
It's strange to me how I can do a task a simple as texting and it heats up though.
How long did you have the borked S3 for?
I 2nd the bad carrier coverage notion. Just as a test, I put my phone into airplane mode while watching a video. I watched the same video while out of airplane mode. The battery drained faster while on the carrier's network than not. I noticed the signal meter was at 3 bars before I played the video.

Better Through Time
I decided to instal CM10 on my phone and it really did help.
I just got home from school/finished most of my day and here's the update:
63% left
9h 45m 29s on battery
1h 21m 33s screen on time
This makes me feel so much better considering that I actually used the device more today than ever before.
(HD YouTube videos, streamed Spotify, lots of internet browsing, more calls/texts.)
Even with the added usage CM10 seemed to have improved my battery life by a lot!
Not sure if I can totally attribute it to CM10 or just more charge cycles, but everything seems to be working better for me.
Thanks for all of the help!
The phone still runs hot sometimes but it has decreased over the last couple of days.
I have noticed on my phone that since installing Liquid Smooth rom has resulted in much better battery life than on the stock rom. However, ever since I have owned the phone, if i have the screen on for more than 10 minutes or so the screen gets really warm right above the home button. Anybody else experiencing this?

Same problem. I just assume that's where the processor is? It doesn't bother me. Its quite funny because the top of my screen is cold. And it doesn't get hot when I'm using it for browsing, texting, the usual. Not unless I play a game.

I'm assuming that Samsung's stock TouchWiz isn't as optimized as the ROMs that the devs make on here.
Which is a definite plus to having a device that has a strong community of developers behind it.
That happens to me as well. I have kind of gotten used to it. Just slip on a case so when you hold it your hand doesn't get sweaty and you should be fine. I would assume that's where the processor lives, but I am not too certain.
I know most of you already notice this but if you don't:
In Setting/ Power saving mode, check the "CPU power saving" then your phone will be limit to 1.1GHz max from 1.6Ghz.
I would suggest to tick on the "Screen power saving", "background color" and "turn off haptic feedback" to save some extra juice.
LTE on. 24h unplugged. 75% screen brightness. Full heavy haptic feedback. Heavy gaming and Internet use. Phone calls. Texting. 3D live wallpaper. Still 7h screen on time before the phone finally had to be plugged in.
I don't know what you use your phone for but I'm going crazy on mine and can't kill the battery. If you need more juice, then more power to ya. I can't fathom why.

Try a day without charging your phone at your desk. Yesterday I pulled in about 7 hours of on-screen time. That's with LTE and anything else internet intensive you could imagine. The only way you'll overcome that worry you have is to test it out yourself. I'm sure you won't be disappointed.

I would understand this philosophy if the Note 2 didn't have an easily replaceable battery, but in a years time you could replace a poor battery for cheap. Just recently the stand with extra battery and charger was $30 on the Samsung site (it may still be that price)

You do know to "remove bloat" all you had to do was go into the stock app manager in settings and disable anything you didn't want. That is actually a much better solution than "freezing" with TiBu or removing altogether. I'm not convinced root and mods are 100% stable yet. Most people reporting decreased battery life are those that have rooted or modded something. I'm still 100% stock with ATT stuff disabled and batt life is still 7+ hours.

Even bare stock I wasn't getting that much screen on time. So far I've only rooted and changed the kernel. Though today my battery life is starting off good. Yesterday I ticked the power saving option for the screen. I'll post an update tomorrow.
Today I was on for 5.5 hours, screen time of 2.2 and was at 54% with Power Saving On
So I went to bell and grabbed another battery
Time will tell if that helps
I could never reach 5 hours of screen time but could have the phone on for 30+ hours
I cant wait till we get more developer support, I used Francos Kernel with my galaxy nexus and it improved battery by 30 % and made my 8 hours overnight use only 2% battery. I was using 12-17% overnight with my note 2 asleep. Aside from kernels and roms I use this phone exactly the same as I did my Nexus. wifi off, bt off, gps on, push email on, auto brightness

Lithium Ion batteries actually do better if you don't charge it constantly. In other words let it run down a bit before charging. You don't want to always keep "topping it off". But in general these batteries are much more resilient than others.
Just do some research. There's lots of info out there.

Umm, no, it does not. You are stressing the battery out. Unless needed, dont keep the battery below 20%. Its healthier to charge the phone sporatically throughout the day.
These aren't nickel batteries...they dont need to be trained or "cycled"

I'm a battery test engineer so I have played around with Li-ion batts.
If you can keep the phone at cool temperature and charge at 40% and stop at 80% then keep doing 40-80, your battery will last double long

Agreed. Full discharges are not necessary for lithium ion batteries. Full discharges were needed for NiCad or NiMH batteries as they suffered from memory effect. LithIon doesn't suffer from this. With that said, a lot of experts do suggest discharging a LithIon periodically, maybe once a month or every other month.
