I've been through several threads regarding battery drain/poor battery life/no charging/etc. But I have not found any with my same problem.
When I turn my phone off and attempt to charge it a battery icon pops up and disappears. If I try to turn on the screen again nothing happens, when I unplug it from the charger I have to hold down the power button (essentially do a hard reset) to get it to respond to any external input.
Additionally the battery life is not great (I get about 3 1/2 hours of screen time) Just bought a 2700mah anker. And the back of the case can get pretty hot, so much so I can feel it on my leg from my pants pocket.
Anybody have any clue as to whats going on? Or point me in the right direction. Before I try to improve battery life, I just want to make sure my phone is acting as it should.
A little more info:
The hot battery/poor battery life was present before i did anything to the phone.

Running h0tw1r3's CM9 rom
I bought the phone last week off some guy on craigslist, it came in a refurbished box that had a sticker saying 5/31/12 or something.
Thanks in Advance.
This is a known CM9 issue. One that scares me entirely. But once it is turned off, it will flash the charging icon and just go black. I do not know if it charges or not. You may want to try to turn it off (taking note of the battery) and plug it in for 10 to fifteen minutes, turn it on through CWM and see if the battery improved at all. I tried it on a CM9 derivative and it seemed to work. Give it a shot before running the battery dead.
PS. This phone runs hot unfortunately :/ May want try undervolting to get the heat down a bit. (GB rom only)

Happened to me today. Pull battery. Press power button two or three times. Put back in battery. Plug it up and leave it for 5min. Unplug. Pull battery. Press power button two or three times. Put the battery back and it should start up.

well i will give the battery life tricks a go i suppose. thanks for pointing to the CM9 issue. I will look into that.
Note: I have since fully charged my new anker battery and have 16.5 min of screen time and 2h18min of time since disconnected. I am at 86% wifi & gps on and backlight all the way low. this is no where near what I would expect. fellow xda'ers please advise, thanks.

People either report the most amazing battery life or the worst they have ever seen. I believe it dependsupon a number of factors but hopefully some of the people reporting a good life span in this thread will be able to shed light on your drainage issue.

Seems to me that the Anker batteries are hit or miss. If anything, they're probably not actually 2700 mah, and rather 2500 or less. I would go back to your stock battery as your primary.
That being said, do you have apps set to sync often? Because I usually get about 4 hours of screen on time, 16 total on a charge, so I could see the half hour less screen time being attributed to sync. Also, grab CPU spy from the market to see if your phone is going into deep sleep with the screen off. You could be having some rogue app keeping your phone in a wakelock.

If you want help, you need to provide more details. I have 2 notes, since may. Neither have over heating issues. One is fully stock, the other I have tinkered with quite a bit.
If your battery is getting hot, you probably have a rogue app. I don't know if a battery Cal works on this phone, wouldn't hurt to look into it.
Fully charge your battery and let it take it's course. Before recharging, take a screen shot and post it here.

Am I the only one that is like Wow. 3 and a 1/2 on screen time, thats great! lol. I get 2 1/2 mostly because all of the on screen time is using internet the whole time, no music, no games, no reading books or anything, just constant internet usage from apps that require internet. Im sure i could get a lot more playing a video or a game.
Guys,
thanks for (most of) the comments. I believe the battery life issues were due to me not using the official charger. I'm monitoring it with BMW and a few terminal commands. Will keep you all posted when the results are in.
When draining the battery down using splash top viewing a video I got upwards of 5hrs of screen time on wifi . But I was plugged in intermittently so I have to another drain to 'calibrate' BMW pro (at the expense of battery life). Stay tuned.
Here are my results today. This is 90 percent lte throughout the day at work. Is it what my atrix got? No. But I would never expect that with so much more screen, plus, atrix wasn't lte. I'm on meso-remix with Tsf launcher. Was on trebuchet before today.

Also, I think when cm9 based roms completely die, they take some effort to reboot, at least mine does and I've seen other odd reports of charging while off behaving oddly. Usually have to boot cwm then reboot, else it just vibrates and does nothing.
I think the key to battery life is trying to stay on wifi as much as possible because lte sucks down juice.

All on wifi, no tweaks. Maybe few minutes off wifi.

Get an app like better battery stats and check for wake locks. My wife's skyrocket would die in 3 hrs of use. Turned out the email kept the phone fully awake the whole time. Swapped out her email to Samsung's and no more wake lock. The battery gauge in settings doesn't show the truly useful information. Through XDA that app is free.

What is your charging practice exactly?
I would normally charge to 100% and wait till it goes down to 0...at first it took around 3 hours for full charge but now its almost taking 5 hours go get a full charge

You know there has been a charge fix released like half a day after alpha 0 was released to the public. In fact the newest build is now 0.5 alpha, which makes your issue a problem of not updating. Seriously though, update to the newest build.

NEVER let it get to zero! You will ruin the battery.
Keep it on charge as much as you can.
You may already have done damage.

Are you serious? These batteries degrade with each charge. Constantly charging is a bad idea.
But the battery degrades when left on zero. When I was on xron I left my touchpad dead a lot. Now I can definitely feel it not lasting as long anymore. Although it could be cm9

Thats odd... I can go days with my TP on one charge... I don't use it during the day (at work), but it's on, screen off. I used it alot at night and read before I go to bed, but just turn the screen off. I also bought setcpu and have some profile set up so when I don't need the computing power I underclock it and when I need it I overclock it. Do the same with my phone and it really extends battery life.
I'm seeing really good battery life with A 0.5. I saw good battery life with A 0 too, and evervolv. Like 6-8 hours of screen on actual browsing use. I see almost no battery drain with the screen off. I can easily go a few days between charges. I don't know the charge time because I have a Touchstone. So, when it drops to less than 50% I leave it on the touchstone overnight. I use the app dock nothingness so that it won't wake up and keep the screen on.
Check you don't have any apps preventing sleep. BetterBatteryStats should identify any apps causing a wake lock. CPUspy will also help you verify the CPU is entering deep sleep when you turn off the screen. The very first build had a wake lock that wasn't caused by any app, but the charge fix fixed it. I noticed on the very first build the light on the button of mine was always on, even with screen off.

I'm afraid you're incorrect.
Allowing a lithium battery to repeatedly go low will cause serious damage and pull down usable life and capacity.
Constantly charging to Max and the monitoring circuits will take what's needed and no more so you are only putting back what's used.
It's not charging any more than you use so there is no added degrade.
Plus if you have the device on charge as much as possible then the cells attain their max capacity.
About 3hrs with CM9, from full charge. Wifi and display pull all the juice.
I would reflash and start from scratch. Sounds like a process going rogue, I get 12 hrs or so on a full charge reading and browsing.

I have no idea how to explain your situation but I know my battery life is better with CM9 than it was with CM7 - and that wasn't bad to start with.
for me battery still working good, is holding all day whit the wifi, no using hard way and in sleep mode i can be 2 days whitout chargin, i just use it to browse some webs
So in the last few weeks, my standby time has gone down a great deal. I have power efficiency and power saver turned on. All of my accounts are on manual sync and I don't sync them because I am trying to get an idea of what is sucking away my power. My screen brightness is set to 20% and I hardly use my phone for calls during the day as I use my desk phone for that. Wifi and bluetooth are disabled. I really have a love/hate relationship with this phone.
Anyone have any ideas?
I'm actually on the same boat. Just this morning I unplugged it...battery said 100% then 4.5hrs later its down to 17%. The phone was running pretty hot too...I even mentioned it too my wife and she said it was pretty hot. Not doing too much with it while it happened. Just woke up ...poked around on xda and fb. Then took my lil one to the bus stop while taking the dog for a walk..come 11oclock my phone was at 17%....I'm gonna wipe and start all over..hopefully it gets whatever is causing the issues. I usually get a good 10-16 hrs depending on use.

download badass battery from the market, it will tell you everything!
Two days ago my amaze started doing what you describe,battery life from 100% to 10% in about 5 hrs MAX, also the phone was very hot, so I pull out the battery but with no results. I notice that 4g was always downloading data, I verified the running services on the phone and discover the calendar apk was rebooting like crazy...the real problem was peep calendar sync was somehow stuck and after turning it to manual voilá! problem solved, temperature goes down, 4g stopped working and battery stopped draining. hope this help think you may found a solution verifying running services.
My amaze is 100% stock.
What helped my battery life was reducing sync frequency. Coming from a MT4G, I was used to updating work mail every 5 minutes. Changed all my sync timers to 1 hour and my battery life improved from 6 hours (including standby) to over 20 hours. I also disabled wifi increased performance (I had previously enabled it) and used medium brightness. A shame, that last one, because the screen is beautiful at full brightness.
That's weird. I have everything synced and I still get about 6 hours a day of use. Of course not heavy use though.
OK, I installed badass battery. I also turned off the weather widget. I removed my phone from the charger at 730am this morning and at 330pm, my battery is at 95% according to badass battery. I also turned off the wallpaper I was using that was displaying 4 clocks in 4 diffent time zones. I wouldn't have thought that those 2 things would drain the battery like it was.
Like I said........Love/Hate relationship.
I installed screen filter from the market last night and used it to turn off the backlight from the hardware buttons, and I also reduced the sync frequency like someone else said (and turned some useless ones off completely). I unplugged my phone at about 8:50 a.m. this morning. It is now 7:53 p.m., and my battery has only lost 22% of its charge (unheard of for me after 11 hours). Don't know which of those helped more, but my battery life is definitely a lot better.

Wow! I wish I had battery power like that. I was on NRG's ROM but found the battery to be draining pretty fast (~7 hours with moderate use). I installed fourth bar sense last night because of all the positive battery reviews I heard. Removed my charger at 700AM, it is now almost 830AM and I am at 88% with light use (drained too fast for 1.5 hours in minimal use IMO). I am trying to control the syncing and its auto-brightness

That's almost too hard to believe! You don't have Gmail?
Are you rooted and using a custom rom?
Really depends on what's running, live wallpaper will definitely suck the life out of a battery but other apps do as well. I installed an auto loan program once and over the next couple of days my battery life seemed possessed, you could almost watch it drain, 60, 59, 58.... so I uninstalling things and when I got to that it went back to normal. Not sure what causes this, sloppy programming, nefarious evil things, who knows. I never have always connected anything, that's just asking for a kick me. I also use custom roms and that really makes a big impact on the plus side. I get a good full day of pretty heavy use out of my amaze but I also have a spare Anker battery just in case, that to me is cheap insurance especially on the road.

I am not sure how that is possible as I wouldn't think the soft key lighting would suck much battery life, not to mention I use that app and get no where near those hours. I know sync will increase it, but that much? Got a screen shot of this claim?
Even in stand by mode, the battery drops more than 30% for me in 8 hours if I forget to charge it overnight.

I pull mine off the charger at 7:00 and at 3pm or so it's down to 85%, I'll put it on the charger at work until I leave around 5-6pm (mainly because I'm used to having to do this on my previous phone) and at night if I'm not using it constantly it's around 70-75% when I plug it in at bed time.
I suspect anyone getting that bad of battery life must be using it constantly, ie: Playing games, browsing, trolling facebook, etc.. Even in the "new toy" stage I'm getting great battery life.
FYI I don't have LTE, but do generally have good 4G.
You honestly can't use any phone on GPS without external power and expect that you're not going to discharge quickly. Assuming that you are running a car charger during GPS and just didn't say so, search the i-717 threads, since the topic has been well vetted on what chargers are more effective,etc. There are definite differences.

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.
When I first got my i717 and was using it on the stock rom I had pretty terrible battery life. I take it off the charger at 5:00am and had decent battery life (around 5 to 7 hours without GPS) but I use my phone a lot for internet/email. I think your battery life is completely normal given your usage.
Most people get about 5hrs screen on time. Total on battery ranges up to about 24hrs, but only if the screen is off at least 19 of them.

I had GPS running on my phone for 4 hours today, had blue tooth on half the time without knowing it, sending text messages, making two 5 min phone calls, checking maps, checking FML and reading a book for about an hour and drained down to about 70% and I have the brightness set at auto. I would exchange it for a new battery.
On average with several texts per hour, several 5-10 min phone calls, taking a few pics and uploading them to picasa, checking facebook, updating status and checking emails I can pull off the charger at 630am and still have 50% battery (at least) by 630pm.
I do have the juicedefender (which isn't crap, it turns off signal after so long so you aren't trolling for signals when you aren't on the phone).

I had a ss of my buddies yesterday, but can't restore mms lol. There are plenty of other ss in the note section. He was at 22+ hrs with about 4:30 of screen on and some % remaining. I have to charge around 7-9 everynight at 4-4:30 hrs screen on, but my use is pretty heavy. I sync 4 gmail accounts, a separate GV, 3 calendars, and several apps.
If yours is much worse than that, you likely have a few troublesome apps or are playing games. First, after a full charge, reset cpuspy timers, lock it, and set it down for a few hours (I know, impossible). Then check to see that your CPU has been in deep sleep about 95% of the time. If not, use better battery stats to see what has been request wakelocks. Not only the most total time, but the total number. Any app that looks outrageous, freeze it or uninstall it. For system processes that look troublesome, Google. You can often find simple tricks online that will tell you what's causing them to go crazy. Beyond that, turn off syncing of anything that isn't needed or doesn't matter (like Facebook), and uninstall stuff you never use.
Another slight help is the brightness widget (don't use the actual widget, just put the app on your homescreen, it works the same) or dimmer in market as they can both set the brightness to a value of 10 (Samsung lowest stock is 20), and even if you can't tell the difference, it helps. Jkay settings in saurom can set the auto brightness profile slightly darker than stock. Umm, and the obvious, use less Widgets, longer sync intervals, processor scaling and speed profiles, and buy a couple rapid chargers, wall and auto.
A couple things to note after seeing a few of these posts...
BT can be on, but without it searching, connected, or listening it's not active.
GPS isn't active unless its in use aand you see the icon in the notification bar. That being said, fb, websites, and many other apps that request location will activate it.

YOU MUST CALIBERATE THE BATTERY!! I have no issues I use my phone heavy all day and get 15 hours and I still have 20% left. All you have to do is
1) Charge you phone until it says "charged"
2)Leave phone plugged in and power off and let it charge until the battery meter literally says "100" (screen will sleep so you can check with volume rocker to light screen)
3) power on phone and let boot and than power off and wait till you see 100% again
4) now keep doin this and you will notice it will start displaying "100%" faster and faster usually takes 6-7 times cycling like this
5) After you do this download Battery Caliberation (root required) app from market and hit the caliberate button and boom your good to go
I do this on every android phone I own when I flash a new rom or purchase a fresh one. Everyone should do this everytime you flash a new rom and I can CONFIRM significant battery longevity on all my android phones I have done this with
You only have to do it once so just get it out the way and you'll get through a whole dayand have some juice to play with.
I get 15+ hours and do not any battery juice defender apps

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.

Just to be clear here, Tasker has nothing to do with battery life. It doesn't hurt it, nor "help" it. However, you certainly could write tasks/contexts that would decrease battery life, and there are a few scripts out there which do silly stuff like autokilling, etc... But if we're talking "battery savings", Tasker and JD do not go in the same category.
IMO JD is only useful if you're frequently in an area with no signal, like you work in a basement or deep inside of a solidly constructed building. Since you mentioned Tasker, in this context it does help me a bit on battery because my wifi turns off when I leave the house, but that's also something JD can help with. If you don't have a wifi connection it'll turn off wifi (and I believe turn it back on periodically to see if there's one available?) I don't use JD, so can't speak too much for it.

Hour? Hour and a half? I'm working during that period. I usually hit news sites and G+ when I'm first at my desk in the morning, so that's 30 minutes or so off and on looking at it, then perhaps an hour over the rest of the day, sometimes more at lunch.
I'll look closer today and post back.

This is my 4th note. The 3 I had previously the battery lasted a long time. I kept the same battery from the first one in all three exchanges. I took the new battery for this fourth one. Could this battery be a bad one or should I return the phone again for a 5th time. I don't wanna take a chance getting a phone with the problems I had on the other 3.
Just looking for some opinions

Good Lord, 3 exchanges! Wow... try running the battery all the way dead where the phone shuts itself down, keep it on the charger and charge it overnight (or in the realm of 8 hours) while leaving it off and see if that makes a difference. I ran my batt that way once and I'm getting 18 or so hours per charge (depending on how much I play with it).

Reflash your modem, rom, and kernel. See if that helps
I only get about 3 hours of screen time myself. Seems normal for this phone. The huge screen eat up battery fast. Plus if your using LTE, so good bye to your battery.
I don't think you have a bad phone, That's just how it is in my opinion...
so whats your total at the end.. like say.. 5%..?
If you're getting about 3hrs screen time, I'd say you'd be on par with what I'm getting. Some days I can eek out close to 5 hours screen time, usually on the weekends when im at home and on WiFi.

Considering the size of the screen I am getting decent battery life, sounds like what your experiencing is normal :/ but going through 3 phones must be very frustrating.

Auto Brightness?
I don't know why you guys are getting such horrible times. With regular use I'm getting an average of 8-10 hrs screen time, depending on what I'm doing. I'm running Saurom RCVI, with Da_g OC Kernel, and tweaked a few of the JKay settings. I recommend charging to 100%, wiping batter stats, and doing a power cycle on it. That's what I did after installing above Rom/Kernel, and battery went from from 4-5hrs to at a minimum 7hrs.

I would like to see a screen shot of that
Fighting battery problems here as well. I'd assume it was normal for this phone, except when I see people posting great times.
1 week old phone. Switched to Saurom yesterday to see if it's any better. Screen regularly at 5%. Usually on Wifi most of the day (and I'm not in an LTE market yet). I set all my synchs (rss, weather) to 4 hours. Others (Twitter) are manual. Only Exchange Email is push.
Using Cpusy & BetterBatteryStats to try to see what's going on. Could be a bad battery - could be that the number I'm seeing is wrong.
Anyway, I'm getting about a 7% drain an hour *with the phone off* ! I'm even rebooting as needed to make sure it's in deep sleep & not 384 (which is very, very annoying). Unplugging the phone @ 7am means a dead battery by 3pm. And if I'm using the phone, it's more like 12-15% an hour (min screen, reading a book). Been charging in the car and at work - whenever I can for now.
Going to try to run some tests on the new rom. Leave phone off for 30-60 minutes & track % loss. Then, maybe put it in airplane mode & try again.
Some weird ones I see to often - Adfree, Maps, Alarm Manager (which I understand can come from almost any of my apps). Oh - tried Juice Defender, no help there either (didn't make any difference at all)
Finally, in the car with Waze (gps), a Podcast Playing, and the screen cranked up for visibility - the car dock/charger keeps the phone about even. On my HD2, a drive to work would charge up like 20-30% of my phone.
Really, really hope I don't need to carry a 2nd battery for days when I can't keep the phone charging.

How often do you get exchange emails? I stopped using push exchange email as it was a huge drain on the battery with the volume of emails I get...
With this phone the screen draws some serious juice, so if your using you phone in the car with the screen on its using about 950mah of juice, so your car charger will likely only keep this phone from losing power, it may not gain any juice, and it may even loose juice depending on charger power and what the phone is doing currently.
This is also why most of us are seeing about 3 hours of screen on time, as while the screen is on its using probably 700-800mah of power. divide that by the 2500mah battery and you can see why...
You can try other programs to try and help with things like background data, undervolting, etc, but that's all going to have a small effect as the "problem" is the screen, its eats up most of your juice. If you want to save battery you need to go after the big thing, the screen, not the little things. However short of reducing the brightness there's not a ton you can do about the screen. It is a big screen, and it needs big power to drive it.

I *think* (need to double check) that the charger is putting out 1A. Where did you get the 950m number from? Is there an appx. chart for different levels of screen brightness (how about 50% for example when in the car? oh - and how much lower is the 5% I use indoors?)
Agree, the #1 thing is the screen itself, which is why I get very confused when I have the large drain with the screen off.
I'll also have to try a test today where I turn on my podcast, but leave Waze off - and turn the screen off while it's charging in the car.

950mah is an educated guess. If you have root you can run this in a terminal to see how much power you car charger is giving the phone... (su first)
cat /sys/class/power_supply/battery/batt_current_adc
I usually get about 9100 for a result, which is 910.0 mah. and my phone will charge barely if I dont have gps going (screen on). if screen is on and gps is on the phone will slowly discharge, so that puts the phone power usage at about 900mah with screen on, so maybe 950 was too high of a guess. So when the phone screen is on, your using a ton of juice for such a small battery.
If I use just a podcast app and the screen is off the phone will charge much faster while in the car. If I have google maps running, it stays almost even...
You could even calculate your usage. She how many minutes your were driving with the screen off and the phone charging and note the amount of battery% gained in those minutes. You'd see a huge difference in charging times with the screen off. In my 50 minute commute to work, I gain about 20% battery charging with the screen off... With the screen on, I see almost nothing.
Seems like some days are better than others.

So I got my GS3 in the mail last night, overnight shipping is an amazing thing. The phone looks and feels great, I'm very pleased with it in all ways imaginable but one....my battery is dropping power like theres no tomorrow.
I left my device to do a full charge over night. Unplugged it when I left for work at 7:45am. It is now 9:35am and my battery went from 100% to 83% with the majority of that time spent in sleep mode. The built in battery monitor was showing my display taking 71% of my battery power....thats insane. I got it so late last night that all I had time to do was setup my sim card and configure the phone with my personal data. I haven't even installed anything yet. All screens are still factory default.
I'm at work currently and just did a full factory reset. Battery usage on display now shows 53% and increasing. I have dropped brightness to nothing and still the display is leeching power. At this point I don't know what to do.

compared to many of the other battery posts it seems like yours might have a bad one, not sure. That drainage doesn't sound normal but I have no hands-on exp with the phone yet

Any advice on a reliable\trustworthy battery calibrator app?
And yea, I understand I may have got my hands on a (hopefully) rare bad battery. But the display usage seems extreme to me. I suppose that'll be adjusted with calibration though?
Sorry for my noobiness. Prior to receiving this SG3 I was an Iphone4 user with an Asus Transformer TF101 tablet. Got the tablet after the iphone to experience the android OS for the first time, which is what led me to exchange my iphone for a SG3. I have some working knowledge of Android, but strictly from a tablet perspective.
To my knowledge battery calibration on this device is the same as the S2....which means calibration apps a deleting battery stats does not work. The best calibration you can do at that point is to pull the battery for like five minutes and then put it back in.

Yes I use wifi. I have little to no use for data plans, so I typically buy my cell phone at full price to eliminate high monthly fees (canada data rates are retarded), and ensure I'm not locked into a contract.
So yes, I always run wifi so when I'm at a location with wifi I get some added functionality.
On or off however, the affect on the drain is not even noticeable.
I'm still continuing my phone charge to 100%. This time I'm using a power outlet rather than a computer usb port. We'll see if things are any different when its done. Currently at 98% and charging.
Well the battery showed 100% at 10:53
Pulled battery and put back in at 10:58
By 11:01 battery% dropped to 98%
Guess all I can do now is try and drain the battery completely and then try another full charge.

11:25 battery is now 95%

I knew you were using wifi. Look at my topic a little bit below yours. It's called the "Battery Drain almost solved."
It's wifi that is killing your battery. Have it set to turn off when it enters deep sleep. The WiFi is not regulating it's power draw. When your phone sleep wifi stays on like you are downloading something when it should be turning off and sleeping as well.
I'm trying to make this more widely known so Samsung can fix it.
I did see that post before starting my own, which is why I turned wifi off completely to test my own battery issues before posting. But I saw no difference in battery performance. And the display usage still showed 60-70% use of the battery, even with brightness turned low and the screen spending most of its time in sleep
edit:
sigh, now the phone is making look the fool because I decided to test again with wifi turned off and I'm noticing a slight improvement in battery longevity. Display usage still shows a scary 55% of usage even it the screen remains off 90% of the time and I just wake it up to view current battery stats
