have u got spare parts? open it up and look at battery history and the running vs screen on time.
they should be the same but i can almost guarantee that your phone is still running whilst the screen is off. you need to find out the app which is keeping a wakelock on ur device and delete/change its settings

Ok thanx..will try this

Sorry for the noobish question, but can I compare the two. I went to spare parts and could not see where to compare screen on time vs running.
I recently tried to calibrate y battery, but sinse my screen does not shut off on its own as before. I've aleady checked the screen timers and all is as it was before.
Right now I am @ 4.5 hrs since I unplugged and I am sitting @ 76%, with little use...kinda sucks!!!!

What kinds of widgets do you have running in the background and how often are they pulling data?
Also, how many days have you been on CM 6.1? I upgraded from RC3 and my battery life is much improved. The first two days it was eating a lot as it 'calibrated' itself but now I can easily make it through a full days use with about 40% to spare.
I adjusted my background widgets and how often they pulled data and this really helped my battery life. Also, a poor signal can have VERY ADVERSE affects on battery life. For example, I work in a prison where cell phone reception is awful. If I am at work for 3 hours and leave the phone in 3G mode, I can easily go through 30% battery while the phone tries to find a signal...

Any idea how long will it take the batt tocalibrate???? I did the recalibration process on thurday night, and my battery sucks now.
I'm sitting on 49% only 4 hours unplugged. Before I was getting somewhere around 55-60% at this time interval...
Any ideas?

Alright boys try this. I got over 2 days worth of lifetime with this set up.
-Download SetCPU
Set your profile to 245/245 screen off with priority at 100%.
-Turn brightness to 0%
-Turn GPS off (Go to Settings->Location and Security-> turn off all that GPS crap
-Leave 3G off until you actually need it, then turn it back off after you're done with it
-Leave bluetooth off
-Don't have garbage widgets lying all over the place on 7 homescreens. I only have like 5 widgets spread out on 2 homescreens.
Are you guys running CM 6.1? Cause I am.
Did you guys overclock?
Thank me if it worked out for you =P

Convolution Thanks for the reply, but im more interested in getting a few more hours but with certain level of freedom. I am not all that interested in switching things on and off every time I need them, but I understand what you mean.
I'm looking to get 16 hours of moderate use...that should be plenty. I currently turn off wi-fi and gps since I seldom use gs, and wifi is governed by a profile manager, and it's on only at night.
but setting connection down to 2G, and killing all screen brightness renders the device (IMHO) useless. Also, SetCPU @245 100%, would really hinder the device.
I am running CM6.1 Stable and I am running OC'd @ 1497, but on "On Demand" profile, so to use only as needed.
I still have to try Pershoot's kernel, I think I will flash it tonight to see what happens.
I am also experiencing some oddity with my screen time-out feature...it's not working.....my screen refuses to turn off by itself, I have to lock the device physically for it to take effect....not sure what changed...but the regular parameters are set properly.

I'm getting 2-3 days with the stock WWE ROM that came with the phone. Brightness is set to Auto, but I keep GPS, BT, WiFi and mobile data connection off until I need them. Other than that, I talk about 20-40 mins/day, send out a few texts, listen to the radio, read my feeds and e-mail - pretty much everything the phone was made for.
IMHO, the "calibration" is bullcrap, it's just an impression that it lasts longer afterwards.

Basically the same setup I have in terms of connectivity except for data.....does it really have that much impact on battery life?
What would I missing if I decide to turn data off?
Thanks!

Huge impact. Try it out for a day or two. Or just install Juice Defender, which disables it while the screen is off, turning it on at set intervals (like for 1 min every half hour) to let it sync.

Thanks Keinengel....I'll look up Juice Defender...sounds like the right thing!

i get atleast a day and a half out of my phone and i had it for about a week now. best battery ive had for a while now.

Wow guys...installed juice defender and pershoot's kernel, and only gone 1% in about 2.5 hour....I'll report again tomorrow

are you using a custom ROM? I'm kinda new to Samsung devices, but I know HTC's Sense was a battery hog, so I'm sure Touchwiz is the same.
Try installing CM9 or AOKP build 37.
I have AOKP Build 37 installed and my battery lasts the whole day.

Wrong section by the way. It should be in Q and A, not general.

Try a different rom, tfe16 has been the best yet for me and agat has an updated version coming soon. Also dont use 4g, wifi, gps etc unless you need them. Solid black background and lockscreen, inverted apps and dark settings. Ditch facebook twitter and crap like that that updates and burns battery.

Basically if you don't use your phone, your battery is awesome...

Go outside and play instead of sitting on your phone youtube'in

Whatever guys that stuff applies to any mobile device. Turn off stuff you arent using, ditch the live wallpapers, worthless apps, and status updates and you get more battery life. You want to surf, download, stream then by all means toggle wifi or 4g on but no reason to leave it on while you are doing nothing. Same goes with gps and bluetooth.

With the exact same setup I have now, I get 20-30 hours on gingerbread. On cm9... I get five.
I don't leave wifi on. Don't leave 4G on. Usually have a minimal screen on time of around thirty freaking minutes.
Don't tell me that I need to cripple my phone (i use it for business). Because there is something clearly wrong. I suspect it is the kernel. I don't have unnecessary apps installed (aside from ones that work great with gb). Don't use a live wallpaper. I do however, refuse to disable auto syncing.
There is clearly an issue with ICS.
I'm not going to turn my smartphone into a paperweight like you suggest.

Not using stuff you don't need is hardly crippling your phone its smart use. I never said anything about turning off auto sync either but you should be selective what you sync. Google plus, drive, picasa all sync pics and other crap in the background without telling you and it kills your battery especially if you are in a bad signal area. Figure out whats draining your battery by using better battery stats and apps like system panel lite http://forum.xda-developers.com/showthread.php?t=1179809
Honestly though try another rom and do a clean install. If you get 80% less battery life no amount of tweaks will fix it and the ics leaks are good now. Several months ago the battery life was half of gb and now they are about the same.

Trust me, I've done all this. I have the same battery life with ICS now that I did a couple months ago. Going to stock, it is wonderful. Had my battery tested by sprint yesterday, it's fine. So, i'm just waiting for a real kernel and hoping for the best.

Turn off LED notifications they're a known issue for wake-lock.

I get terrible battery life on alpha 5. Change to a stock kernel might help.

Kobridge's tweaks http://forum.xda-developers.com/showthread.php?t=1668853 along with Badass Battery and CPU Spy have helped me trace battery drainers. Also wholeheartedly agree turning off apk's and functions that are of specious value helps greatly ie.( auto rotate, auto brightness, dialing back on sync; etc.)
Good luck

[Q] Is this acceptable battery life?

So I unplugged the phone at 7am in the morning,its almost 12 hours since.
My Usage was browsing 20 mins,facebook 10 mins, 5-10 texts, few apps installation,5-10 emails,5 min instagram,10 minutes of calls, 5-10 minutes reading pulse,GPS on for 5-10 minutes
And general other things using the screen to look up contacts etc.
These are the screenshots below.
Im running everything stock jellybean 4.1.1,stock rom,stock kernel. Its rooted and installed flash apk.
Now i would like to know is this really light Usage?
For this usage,is the battery life good or can it be made better?
Thank you for your time!

Check your location settings in Maps. It seems Google Now is using up the battery by using the "Update Location" feature on my phone.

Yep the location settings are all enabled.

I think the "Location" features in Google Now need some fine tuning. I believe Google Now requires that you have location updating turned on to work so I have opted to turn off Google Now to see if Google will make it more efficient in the future.

But does this constitute average battery life?

And this is the screen usage time.
Sent from my Galaxy Nexus using xda app-developers app

Maybe I've always had below average battery life, but if I'm on any rom and I get 12+ hours of it + around 3 hours of screen on time. I usually consider it average. But that's basically what I've got on any rom/kernel, even stock.

At least your Nexus has better battery life than mine!
I'm using stock JB JRO03C ROM with stock kernel + XXLF1 radio baseband and with 3 hours screen using will drain my Nexus's battery too quick...
I gonna buy extended battery for my GSM Nexus but it will not help really much, maybe I gonna test Jame Bond kernel for Jelly Bean if that gives better battery life to my Nexus..

I'd just checked mine and I'd gotten about 15 hours with at least 100 texts, 4 5 minute calls, 2 hours of music playing through headphones, constant facebook checking, and wifi on for 50% of battery time all with google now turned on and when put on charge still had about 30% batt. left.
I am using the jelly belly v3 rom though so can't speak for stock.

Try reducing the display brightness, it's the biggest factor in battery-drainage for me.

The display is at quite a low level. Maybe I need to flash other Roms to get better battery life.
For example right now.
My phone has been unplugged for roughly 2 1/2 hours. And I'm down to 86% and the screen usage time is only 33 minutes.

That roughly translates to 17 1/2 hours with 3 1/2 hours screen on time. Which is pretty average depending on what apps you use.
Could you provide more details like what apps/widgets you have with what sync settings you're using, email accounts, weather, etc?
Also, what variant of the Nexus are you using? GSM? Verizon? And are you using the stock battery or an extended?

Am getting 11hours 30 minutes now with 10% left.Thats worse than yesterday with pretty much the same usage. Infact i defaulted to 2G networks and didnt even use 3G.
Sure,Im using the stock weather widget and what's this song widget.
The apps that i use daily are pulse,facebook,twitter,gmail,messages,people,speedtest(maybe once or twice a day),xda,gallery,google talk,dropbox and Gtasks.
2 Gmail accounts and 1 other email account are in push sync.
and maybe few pictures with the stock camera app
Im using the GSM international version
Im on stock battery.
The accounts in sync are shown in the screenshot(except for dropbox,everything else is on)

Its even worse now.

Facebook is notorious for battery drain. Check the settings in Facebook and make sure to "uncheck" the location setting. Also, try to switch a couple email accounts to do "hourly" checks instead of push (unless you absolutely need them to be push). Also, try reducing the sync intervals on apps like Pulse and Twitter.
Considering you're using the stock battery the battery life seems on par with the usage your phone is getting even when not using the screen. Push, sync, and apps that use a lot of data transfer (like Dropbox) use significant battery.
I noticed the "Maps" application is using up a good amount of battery in your screenshots which means it's probably updating your location quite a bit and/or you use Navigation. Either way, that eats battery life as well. A lot of apps use location so it would be best to check those settings as well.
Also, depending on when you're using "2G", it could mean it is taking longer to pull data which might lead to battery drain.

Fixing battery drain on your s3

I have done pretty extensive testing in the last few days and this is what I found.
TOUCHWIZZ USERS ONLY, uninstall and delete data for the app my uploads. It syncs your gallery with picasa and uses a load ofdata and battery. It won't break anything. turn off instant upload in Google+. Turn off smart stay and motion actions. they use about every sensor in your phone. Turn off the wake up phrase in s-voice. If its on it is always listening for that phrase. I'll keep looking for other things but I got fairly good battery life just doing those things right there.
When uninstalling an app, wipe cache and data first. This will clear any background processes that could stay after the app is gone.
Install es task manager and kill everything you don't need to run on startup to preserve boot time/battery usage. Also it will keep the processors a lot lower.
All accelerometer and other hardware functions use a significant portion of your battery. If you don't use landscape mode turn auto rotate off because it uses that precious battery life.
Weather bar in notification drop down and on your lockscreen will destroy your battery life. Weather widgets also use quite a bit of battery.
Facebook app also kills your battery because its always connected to the internet. Syncing Facebook account to your phone further wears down your battery. Any game or other app that connects to facebook will also do the same.
Look in data usage under settings. Anything on that list uses more battery because its connected to the internet.
If your not in an lte area turn lte mode off because your device will be searching for a signal it will never get.
Low signal strength kills your battery because your phone has to use more energy to hold connection to the network. If you have WiFi at home and bad cell service (or anywhere) use WiFi because its easier it is for your phone to hold good wifi signal than bad cell signal. also turn off your NFC. It uses more battery than Bluetooth does.
Get better battery stats app and look for wake locks because without deep sleep you will never get more than 12 hours battery life.
Widgets, live wallpapers, lock screen ripples and other things that move use battery also. If you don't use it then remove it to save a couple percent a day.
Remember that when charging through a computer USB port or things like that charge a lot slower than an outlet. Slow charging is better than fast charging because your battery stays cooler and that means your batteries total life will be longer.
Finally before you go in a ROM thread and start complaining about battery life, go at least three charge cycles after flashing to optimize your battery.
There are many things that cause battery drain so beware when you download that next app. It could be a battery sucker. If you don't need or don't use an app. Uninstall it because it may have background processes that are using up battery and RAM.

You can uninstall the facebook app, go to facebook on your browser, create a bookmark, and then place a widget on your homescreen for that bookmark. The site is actually faster than the app.

In my opinion maximizing battery life is all about watching out for the things on your phone that you don't care much about but are using a lot of battery life versus keeping the features you like that make your phone a smart phone.
I leave GPS on all the time, use auto brightness, have fb and fb messenger installed, use Google talk all the time, push my work email, etc. and accept the fact that this will cost me about 2% per hour when my phone is idle. I'm also using the latest ktoonsez kernel & task/kt jellybean rom and those help tremendously on battery life (1h45m since unplugging today, 51m of screen time and I'm at 89%). I have definitely been diligent about turning off the things I don't care about, like latitude, location in Facebook, rom weather, etc. and that helps quite a bit. My biggest problem has been maps running for no reason and draining lots of battery, but that sends to be a lot better with the latest rom and kernel.

ii.Mediaserver. This system process is tricky when it comes to battery. What happens is that whenever you access any sort of media on your external SD card (playing music, gallery, what have you), this process kicks off. Luckily though (but hard to catch), sometimes, this process uses more process time than it should due to corrupted contents on your external SD card. In order to catch this culprit: try clearing your battery stats (for example, restarting your device or coming off AC power), playing some music and/or checking out pictures on your SD card for a few hours. Then, check your processes. If Mediaserver is high up there in usage, you may want to consider cleaning up your SD card. Naturally, we would expect that the process is higher when media contents are in use. I can’t give you a specific guideline such as, "something is up if Mediaserver consumes over 25% battery." This is another example of where you should look up other user stats for system processes based on your specific phone and OS version. If you think your SD card may be corrupted, backup your data, format the device, and slowly, add back files and repeating your media tests. Finding a corrupted file isn’t a guarantee, but this doesn’t hurt if you suspect data corruption.​[/QUOTE]

Turn off GPS when not in need. Turn off WiFi when not near wifi. All the stuff in the op. And undervolted by 100+ mv on every CPU setting. And my phone is absolutely lag free accept when I hit the unlock button it takes like half a second for the screen to come on instead of instantly (160mv undervolted on 192 which is sleep speed I set)

In my opinion maximizing battery life is all about watching out for the things on your phone that you don't care much about but are using a lot of battery life versus keeping the features you like that make your phone a smart phone.
I leave GPS on all the time, use auto brightness, have fb and fb messenger installed, use Google talk all the time, push my work email, etc. and accept the fact that this will cost me about 2% per hour when my phone is idle. I'm also using the latest ktoonsez kernel & task/kt jellybean rom and those help tremendously on battery life (1h45m since unplugging today, 51m of screen time and I'm at 89%). I have definitely been diligent about turning off the things I don't care about, like latitude, location in Facebook, rom weather, etc. and that helps quite a bit. My biggest problem has been maps running for no reason and draining lots of battery, but that sends to be a lot better with the latest rom and kernel.

Maps is known for that. If you don't mind my asking what do you use maps for and could you just use Google now to search locations and it will even give you traffic n stuff. That would probably get you another hour or so a day.

The OS isn't always the reason for battery drain, many factors take into play.
How often you use the device.
Applications like widgets, email push.
Wi-Fi. If your not on it shut it down it else is always going to try to find a signal and drain battery.
Bluetooth. same with this.
Using the net.
Things like Google now, it's always running and trying to update info, shut it off of make intervals longer.
These are just some things to take into account, but at all use the phone different, and im not saying the OS doesn't drain but it solely isn't the only reason.
Hope this help.

I seem to be having the same problem. ..

Same here. With sync turned off, google now turned off, and most everything else that eats battery...
In the battery setting is shows that media is eating at least 25% battery.

I'm having the same issue. I read that the media drain could be caused by bad media files, but I didn't have any issues before this weird.

In my experience when you first update to a new samsung rom, the media using the battery is your phone updating the picasa albums...which stinks because it also eats your data like crazy if you are not on wifi and forget to turn off sync until wifi is available.

I've noticed faster than normal battery drain as well on my device. Normally by 4:30pm I'd be at 40-50%. Now I'm in the 20-30% range.
I'm going to try factory defaulting it soon and run it for a day or two. OR I might not even do that and just go directly to Task's AOKP or CM10.

I am going to flash to tasks tonight, not fond of what I've been reading about cm10.
But guys remember we all use our phones differently, take into account apps, usage, ect
Some days my battery lasts a bit longer than normal but I want using it as much.

i dont have any issues with battery drain, but i would suggest a full restore after upgrade. dont restore using titanium, just install through playstore. then report back but i doubt it will be an issue

Before everyone jumps ship, may want to try a new kernel. KT and a few others should work on the new release. Just make sure you choose one that works on JB TW and not ASOP.

I'm currently a kt kernel for jb twz.. but I'm not really complaining about my bat as I use my phone like a cheap hooker lol

I have the same problem.. After JB update there is huge battery drain. With average usage it drains almost 100%. Before update with heavy usage I was going through the day.
Maybe I should try KT kernel I don't know. I wiped all after updated, nothing saved from ICS.

Try kt kernel and change the governors to suit your usage

Same here,
It's seem the culprit is the android.process.media.
Each time i bootup,android.process.media is running for about 30 min, non-stop.
I already do a factory reset+sd formatting, but no succes.
With startup manager, i can block that process,but you need to be rooted .

I use the same settings as before i did'nt upgrade yet..i got it fully charge with no texting and calls the next 1hr its already 80%..i think i would try to cycle first my battery for 2 more days..then i'll see if it still have heavy drains..thanks for the response guyss.

Check out my overnight drian! from 1:30 to 10 the average drain is around 4% an hour, Losing about 20% overnight doing nothing.

I just got this phone the other day and immediately updated to jelly bean.Though I have nothing to compare it to my battery drain seems normal. I'm losing about 5% an hour but that is with some use (it's new so I'm playing with it a lot).
I did notice more drain the first day of use (may have been because I was using it a lot) and noticed maps was taking up quite a bit of the battery and I wasn't using it. So I uninstalled the updates for Maps and then re installed it. Battery drain seemed much better after that and now the maps app doesn't even show up in the battery report(before it was about 3rd and it seems kinda high on yours as well though you may be using it).

i'm noticing about the same battery consumption as the stock ICS rom. about 1~2% per hour when idle and sitting, 2~5% per hour listening to music over bluetooth with the screen off, and 5~10% per hour surfing the net and watching videos and stuff.

Well after doing probably 5 resets on my phone , it seems like everything is working fine . I was having issues with the battery drain ,internet not connecting, and phone calls taking 2 minutes to connect.

I was having issues with high battery usage as well after updating to JB.
I froze most every app and widget associated with AT&T and Samsung (with the exception of AllShare) and flashed KT747 kernel and set governor to ktoonservative (default settings).
I am really never a heavy user during the day, but with the same usage I had on ICS, I average 15.5 hours (with the phone at approx 15% when I shut it off to charge) - screen on time between 2.5 and 3 hours; call time between 45 min and 1.5 hrs; media (which seems to be a big battery hog) only about 6 minutes. I use bluetooth exclusively, so that radio is on all the time the phone is on. I keep sync and background data on, but only turn mobile data on as needed.
