Hi, this issue is specific to my NON-ROOTED Samsung Galaxy S2. I have seen other simsilar issues for other phones and they don't seem to help. My Battery doesn't seem to last more than a few hours. No more than 5-8 and it's dead. I turned off the Data and wi-fi. I set my Wallpaper to a Black background. It just sits on the desk and after a few hours it's almost dead...
What can I do to fix this?
Rooting is not an option at the moment.. I'm still reading and learning about it as I don't want to create a paperweight and/or void my warranty...
No offence mate but for a start you can search the forum and you will literally find dozens of threads on the very same subject which have been posted on here over the last few months.
Search and you'll find the answers your looking for, a tip freeze the Samsung bloatware in Titanium Backup and your battery life will improve substantially, there are many other methods to improve battery life you can find them yourself.
I get over a full day on heavy usage...
No offense taken, but most point to Rooting my phone...This is not an option for me at this time....I'll look some more, I guess...

Oh right well then your options are limited if your not going to root your phone as regards battery life.

I know...that's why I posted, but I should have said that in my original post...I'll edit it....but I did find something that I will try when I can..Phone is charging in a wall outlet right now, and I don't want to unplug it. lol...I do thank you for your effort and understanding...
I have unrooted phone and get around 17-20 hours heavy usage.
I would suggest you flash a 2.3.5 Rom via Odin as they seem to have better battery management if you haven't done so
http://forum.xda-developers.com/showthread.php?t=1075278
you dont need to be rooted to flash new roms via odin
Also advisable to charge battery till full then use till its like 1% then recharge full and so on to calibrate it a bit.
Rogue apps can eat your battery life as well so If you can afford it do a full wipe and reset if you can and see if it makes a difference.

If her wifi is on and its constanly looking for wifi, will that be the cause? i just told her to turn that off.
What is a Rogue?
Chat applications like Google Talk or Facebook (if you go into Chat) tend to drain battery.

i have the same problem with s i9100 and when connect using my galaxy the battery charged very slowly but charged very quick in galaxy s
the battery in s i9000 more better
You guys need to give more information if you really want decent assistance, there is an app called better battery stats, you want to look at your partial wakelocks section in that particular app, go get it either on this forum or in the Market, post screenshots of your battery graph in Settings>About Phone>Battery Usage and click on the time, also a screenshot of your partial wakelocks will reveal the issue 90% of the time
Also, there is no need to root your phone to achieve good battery life, unless it is found that a system app may be the cause of the poor battery which is hardly ever the case, anyone who points you to rooting to get good battery life has very limited knowledge of android and what is the cause of poor battery life...
Usually downloaded apps and user settings are the cause of poor battery, there is absolutely no need to root to be able to fix those problems.....
I noticed this one too...My stock DXI2 room tend to be a battery hogger and the display consumes around 60% of my entire battery life...
agreed I'm getting nigh on 2 days battery life nowadays maybe one and a half of moderate to high usage! certainly don't need to root and install a new ROM.

Charge your phone fully and use it as you would normally, the screenshots you provided doesn't show much, what you have to do is click on the very top where it says 22h 52m, that would take you to another shot that shows your "screen on" time in a linear graph just below "Awake" time, that's the screen that would tell us if you are having wakelocks.
Secondly, get better battery stats from the market or from this link here then set the display options to "Partial Wakelocks" "since unplugged", remember you do this after using your phone normally from 100% to 50%, this should be able to give us some insight into what is eating your battery, it may be better to let the phone sleep as much as possible, but I know it's pretty hard to leave the device alone......
You should definitely try better battery stats app. It helped me to identify the app that kept my phone awake continuosly. My battery life increased from 8-9 hrs to 15-17 hrs after uninstalling that app. I even bought the paid version from market after that. Must have app!!! Give it a shot. Its free for XDA users. But if it helps you then please do consider buying it to support the developer.
yup. My SGSII is on KJ3 stock & I get easily around 1 day & 16-17 hrs before i need a charge. This is with moderate to heavy usage (depends on your perspective) which includes:
1. Display is on roughly 1.5 to 2 hrs
2. Voice calls roughly 2-3 hrs
3. 100 odd texts
4. 30-40 mins of listening to music
5. 20-30 mins of browsing
6. 30 mins of running benchmarks
7. 10-15 mins of gaming
8. Downloads for 30 mins
8. Auto-sync & background data enabled for 9-10 hrs

Ok, I had the phone plugged in to the laptop to transfer my Memo's from my BB/Outlook over to the phone, so it only says it has been unplugged for 3 min..If you want longer, let me know, as I'll do another one tomorrow.
This one is from 49 min unplugged...
As far as that app. I'll download it now and run it for a day or two and see what happens...will post back soon!
Thanks for all your help people!!!

My non rooted galaxy s ii lasts at least on full day of heavy usage, including 3g, music, and gps. Will last 2 to 3 days if i use it conservatively turning off 3g when not in use.
make sure u have latest update thats basically all i did.
good luck.

Mine goes dead in less than a day, I'm not sure if it's because I rooted my SGS2 or not (chainfire's guide) but then again before I rooted it, I had only used the phone lightly because I didn't know all the functions, but now I know it all.
Anyway, battery life is awful, how are you coping with it? Also are there like genuine branded batters that's bigger than 1650mh that will fit the SGS2?
Edit1:
OK, I have no idea why this is happening, because the default task manager widget on my SGS2 says no apps running, and I've also cleared RAM. I dont understand why, I'm not using some of the programs, like internet or clock etc.
Also, Advanced Task Killer doesn't show xScope 6 or PowerAMP or Clock as running under services, but Battery Usage still picks it up?

Voice Calls: 9%
Clock: 8%

Cell Standby: 5%
PowerAMP: 4%

Edit 2:
Even after I properly exit programs, instead of minimising, it is still using the battery...
The same programes are still using battery even after I turn phone off, then turn phone back on, i immediately check the battery draw, and bam there they are
Really not having any issues with mine, infact im rather impressed. Have 48% battery life left after 12 hours of fairly heavy use is pretty good in my books. Im confident I could get 2 days use out of this thing if i wanted to.
Just do all the obvious battery saving things you can do!
mine lasts me a good 2 days, with moderate to heavy use, still installing all the apps I want and widgets etc.
Could you post your battery stat screens on usage and stuff?
I want to get a better idea by what you mean by heavy
Mine gets close to dying half way through the day with what I guess I would consider heavier usage. "Display" is definitely always the biggest battery hog haha
With Android OS or System coming in second

It seems like some are getting excellent battery life while others get horrible battery life without any kind of consistency. After I unplugged my S2 this morning I used it to surf the web for a few minutes, played a simple 2D game and then left it idling for an hour and it was down to 70%. Now, 5 hours later, with practically no usage at all I'm down to 45%.

Just a thought maybe some of your apps have a start up on boot? btw I don't use any form of task manager, I just let the system go as is. I tried advance task manager and samsungs task manager both were crap not picking up things so I don't even bother.

I guess I must use mine way more than the people here who are claiming all day with heavy use. Because my Display is at 51% right now, and my battery is at 22% after 7 hours
I use mine a lot at work and have the screen on a lot of the time.
I thought these AMOLED screens were supposed to be more efficient than LCD? I could have my iphone 4 screen on all day and I didnt have a battery life problem lol
Hi,
I'm in the same situation. I've found battery life to be so bad I'm on the verge on selling the s2 and buying an iPhone 4. My battery drains at rate of about 1% every 2 mins of use, with the biggest drain being the display. Currently I've lost 28% in 40 mins of use. That's 1% every 1.4 mins.
No apps were running except web browser and wifi.
Would a new battery help? I can't find any official Samsung batteries online, and I don't really want to put a cheap Chinese battery in.
Everyone has updated to XWKE2?
battery life is very poor

I bought a sgs2 two days ago, but the battery is very poor at the moment. Mine buildnumber is XWKE1 and the kernel is 2.6.35.7-i9100xwke1-CL181974root.
how can you update to XWKE2? if i press look for update, then there is no update availible.
battery monitor widget; estimates:
all-time averige = 3h30
average since (un)plug = 6h56
battery (dis)charge = 5h43
offtopic:
Also an weird thing is when the screen goes of and you turn it back on that the sgs2 tries to remove my SD kaart 8gig and then tries to prepair again...
I didn't root my sgs2 (i have a dhd which i have rooted with miui... fantastic!!)
My build says XWKDD, whatever that means. Can someone post noob-friendly upgrade instructions please?

I'm getting results similar to yours, the best I've had so far is 9 hours, with absolutely nothing running, no wifi, and not waking it up. It's ridiculous... I'm hoping I just need a new battery, but like you I can't find any official ones.
I updated to the latest XWKE2 firmware, but it did not have much affect on the battery life. It's still VERY poor. I'm still within the 14 day no quibbles return period, so I'm very tempted to return the phone, or at least ask for a replacement. The frustrating thing is that some people are reporting fantastic battery life.
Play.com are selling replacement S2 batteries from May 20th. You can preorder on their website.
The battery life is really not that bad, here's a post from someone on phandroid;
Scainer said:
Well.... 3 days 3 hours isn't bad from a single charge.. lol (or is that 3d 7h ???)
TBH, the phone was mainly used as a phone with the odd bit of net surfing. No games, and only a GPS sync test e.g. less than 2 minutes.
I only had about 4 calls on it, and data access was only on when I wanted it.
I guess this goes to show that you have the option to use it as a phone rather than a media device and you get a good weekend from it.

And then I tried it out, and I've had my Wifi on all day, had a few phone calls, lots and lots of texting, some browsing, youtube and facebook on wifi and 3g, and a little bit of gps and it's been going for 20 hours and 30 minutes and I still have ~50% of battery left.
If I play games constantly I'll get around 8-10 hours from it so far.
Your one of the lucky ones. I'm lucky to get 7 hours on moderate to heavy use.
Its strange how some people arnt getting normal battery life. A faulty batch perhaps?
Im on 40% battery after 13 hours off charge and ive used it a fair bit today (A couple of 20 min phone calls, some texts, half an hour of angry birds and half an hour of web browsing and i also took about 20 photos aswell) To be honest im massively impressed with the battery performance. My old nexus one was usually down to 10% after a full 12 hour day.
I just hope people arnt getting the impression that the battery life on these phones is bad when theres only a few people having problems (and maybe they have a faulty phone).
mine lasts around 18 hours wifi-on gps-on auto brightness sound on around 15-20 calls a day and 200 texts a day
It's always like this on every device. Really depends on the user, software, and cell strength.
What is the deal with this phone? The battery life is not very good at all. I came from a phone that had a 1150 battery and this one has 1600! I am getting almost identical battery life as my old phone. I am running a fully debloated rom at stock clocks with the display turned all the way down and can HARDLY make it through an 8 hour work day. I've narrowed it down to the screen.
I remember reading about amoled when it was first announced and they said it would consume significantly less power than any other display technology. I'm starting to second guess this.
Its either the screen or the dual core processor that's draining this decent sized battery so fast.

Amoled does. From what ive beem read ing super amoled plus.is alot better. The darker the better. Slcd is.a.good option for battery mizers though.
I voided my warranty and your mum.
Yes ive also read that the way super amoled plus works, is there is no backlight and individual pixels light up, so its better to have simple wallpapers with mostly black, would probably give you better battery life, as most of the screen will no be using any energy.
All android devices murder their batteries. It's nothing new get over it lol.
This device gets decent battery life considering it's the most powerful option out currently though.
The general masses do not understand how to set these phones up for optimal battery life. There are threads all over XDA on how to do this.
This phone for android is probably the best or near best in its class. I am impressed. Its better than my captivate was. I can get through 15 hour days with heavy use all the time with average of 4 hours screen time and i listen to a lot of music when the screen is off. This phone rocks i dont even see the need for a extended battery

I have no idea what you do with your phone or what . But I get more then enough battery with this phone, I do it all text talk surf web forums play and I make it home with enough battery to probably lend you some. Seriously we all know your not going to get iPhone battery life obviously the iPhone it just plain simple. But come on, this type of thread it's getting annoying there's a few already with help and tips on your issue search for them. Maybe you just got high hopes, or maybe it's not the phone it's you. BTW Amoled probably consume less battery but not enough for us power hungry users to see a different.

I don't think is the screen alone itself but the dual-core running at 1.2Ghz might eat more battery than your old phone with an smaller battery

You might want to install CPUSpy and BetterBatteryStats (BBS) so you can better diagnose where your battery issues are coming from. 8 hours seems very poor for this device. Use CPUSpy to see how much your device is running in deep sleep - with light usage I usually see around 80% deep sleep. You can use BBS to look for apps causing excessive wakelocks (BBS is available here on xda) to see if a particular app is causing the problem.
Unless you have a hardware problem, I don't think the display is your problem - the display on this device has a smaller percentage hit on battery use than my 3.2" LCD Aria.

Yet you've completely ignored people who have told you to get CPUSpy and BetterBatteryStats to figure out what's keeping your phone awake.
Most likely your phone is not defective, but you've installed an app that's hogging the battery or set up a configuration option that kills it, such as:
Hotmail calendar sync is known to cause massive battery drain due to a Hotmail server side bug
Some Exchange servers are misconfigured and cause major battery drain
Skype is a battery-hogging nightmare. If you absolutely have to use Skype, make sure to take it out with a task killer when you're done with it.
I haven't really pushed my device with screen-on time, however what are your idle battery drain statistics? If you have drain more than 2-3% per hour when the phone is idle (such as overnight), something is very wrong. You should be getting drain on the order of 1% an hour if you leave the phone overnight in moderate signal.

I havent ignored anyone. You assume that because I haven't responded to such comments that I haven't tried them. I frequently use cpuspy to make sure my phone is sleeping and I use bbs as well.
I'll leave the phone off the charger overnight to check it out though.
This still doesn't change the fact that HEAVY useage at 5+ hours of screen on time is absurd.
I am also planning to experiment with airplane mode and using only wifi tomorrow.

Make sure to do the following to get the most accurate data:
Top off to 100% (to the point you get the full-charged notification)
Remove from charger
Reset timers in CPUspy
Put phone down and go to bed

This still doesn't change the fact that HEAVY useage at 5+ hours of screen on time is absurd.
I am also planning to experiment with airplane mode and using only wifi tomorrow.

I'm not sure why you say 5 hour screen on time with heavy usage is absurd? Are you thinking that isn't possible with this device?

This phone for android is probably the best or near best in its class. I am impressed. Its better than my captivate was. I can get through 15 hour days with heavy use all the time with average of 4 hours screen time and i listen to a lot of music when the screen is off. This phone rocks i dont even see the need for a extended battery

You can still exchange with a new one under 14 days or 30 days. 6 hours with screen on is not absurd on this phone in 12 hours. I have been with screen on with 2:45 hrs and voice with 45 min in 1 day and 8hrs with still 15+ % battery juice left.

IIRC, one of the review or comparison against iPhone4S benchmarked GS2 as 5 to 6 hours of internet browsing which means both screen on and using data. Wi-fi gives it a slightly longer battery life than cell data. Unfortunately, it didn't benchmark video playback time. iPhone4S spec says 8 hours of video. I hope GS2 is close to that. This is play video from local storage, not streaming. So, the data connection battery draw is out of picture. I managed to get 4+ hours of video playback with flight mode on with my old Captivate. Hopefully, GS2 will last longer, e.g. survive a coast to coast flight while still have some juice left for navigation.

He's not lying. I have seen 5 hours of screen on time and still had a little juice left at the end of 16 hour days. And it wasn't a one time deal. Seen it several times, though I usually don't use my phone that heavily. Yesterday I barely used my phone at all and was only down to like 85% after 16 hours.
"Long post warning"
I have really really bad battery life since I got Galaxy S2, I tried everything, never get what people claim(20hours+ battery life).
All I have got is something around 10hrs. I already using official Samsung 2000mAH extended battery.
I never liked root and flash rom but this phone made me do it .
yesterday I flashed to LeoMar75 2.7.1 with CF-root kernel (I read this kernel has best idle battery saving)
and hoping miracle will come and now..I still stuck in battery life agony
Can you guys help me determine what's wrong with my phone? I see A LOT of fellas report their phone can run for 30+ hours with 3G always on, screen time more than 2hours, internet, whatsapp and games
I basically did the same thing , I don't even do games but mine doesn't get pass 10hrs.

today I flashed the rom and kernel and I fully charged the battery then I have like 2 hours screen time for
whatsapp, engadget, FML and stuffs then sleep for 5 hours.
before I sleep, the battery has 57% left and woke up, 33% left.
I can understand 2hours screen on time drain the battery to 57% but I don't understand why 24% of 5 hours idle?
as you can see, my device woke up while I was sleeping and it's idle.
I give you guys some details
can you guys please tell me, which part of my phone is draining the battery ?
Display setting:
1. brightness : 20%
2. auto adjust display power : uncheck
3. display mode - film
Sync
I disabled Gtalk auto login and signed out Google latitude.
I also unchecked the "Backup my data" in Privacy.
I disabled Fast Dormancy.
and here are my app list.
I already did all the tricks I can find on internet to save battery for my S2 but still the battery life is miserable. I hope you guys can help me with this : (
ps. now I doing battery calibration, I think this is my last resort , I really hope my phone can do 20+hours with 3G data always on.
yeah well first of all when flashing a new rom, must wait 2-3 cycles before the battery life is maximised....
2nd of all why the need for both friendcaster and facebook ??
If the drain is still bad I would just recommend turning all data off etc...and seeing if the battery life is normal overnight (2-3% loss)...if not then something ain't right
edit; also check your wakelocks (on betterbattery stats app)

Thanks for your advice man!
do 2-3 cycles will make HUGE difference?
I have 2 facebook account for work and friends, that's why I have both friendcaster and facebook app.
I tried turn off 3G data and Wifi at stock rom(2.3.5) earlier, the drain overnight(8hrs) was within 10% so I pretty sure it's 3G data draining the battery, just don't know which app does it. (I have quite heavy incoming whatsapp msg don't know if that's the case)
sorry I forgot to capture the wakelock screen earlier but now my phone battery is completely dead,
charging it for battery calibration, perhaps I will include it tomorrow. Thanks a lot man

Try disabling facebooks sync for a day and see how battery life is then. I ran into a serious problem where my battery was drained 50% in a matter of hours with zero usage and once I remembered that I recently updated facebook I uninstalled it and everything worked fine again. I re-installed fb but disabled sync and battery life is still excellent, haven't had the chance to enable sync and monitor the battery though.

Turn notifications on for facebook but disable refresh (Set refresh interval to never). You'll get PUSH notifications instead .
are you loggdd into fb chat? If so, that should be it.
I suggest Skype.
I had Skype, Yahoo Mail, Yahoo Messenger, and Facebook installed on my phone before. Got around the same batt life as you.
Reinstalled the rom I had and installed apps one at a time. Those 4 progs are the only ones I know of I have NOT reinstalled and my battery life is usually around 20+ hrs with normal usage.

If you've never logged on then your fine. Skype has always drained my battery, but I don't use it much so uninstalled. Facebook was a battery drainer with the refresh times but now that it has push (I get notifications at the exact same time as I do on my web browser) it doesn't drain my battery at all.
Average battery life is anywhere from 20 hours to 1day & 13 hours. Screen on time is always 3 hours & 30 minutes minimum, most I've had is 5 hours & 30 minutes, that was without playing any strenious games though

wow nice tips! so you suggest even I didn't login Skype, I just let the app sit in there, it still drain battery?
I disabled the facebook refresh interval like you said and yeah I still got notification from PUSH, nice tip : )
I now calibrated the battery, fully charged, did all the tips you guys gave me.
turned on the phone for 1.5 hours with 30mins screen time, (LINE, Facebook, Whatsapp only)
the battery drop from 100% to 88%, is that normal ? (I use 2000maH battery)
with the 2000 mah battery, you should be able to hit 6 - 7hours screen on time. This does depend on your screen brightness however but your drain looks ok based on screen time. Id recommend that you charge the phone to 100% before you sleep, then let it drain overnight so you can check how much battery is drained in idle. With the stock battery, I normally lose around 1% every 4 hours when idle.
As for Skype, it did drain my battery. When I logged out it ran in the background and caused wakelock issues. 3G watchdog also showed that it would use data every 20-30 mins. I'm now using droidwall to block internet for apps that don't need it. For example I won't be downloading wallpapers from the "Flikie Wallpapers" app whilst using mobile data, so I set it to only use internet when I'm on wifi

I have the same problem so i'm following this topic very carefully
Hope you'll find the solution !
one thing to remember as well, A LOT of people with 20 hour battery life have hardly touched the phone. Some people can get 3 days worth of battery, but with a screen on time of only 50 minutes its hardly surprising. I'd say anything over 24 hours with a screen on time of 3 hours is very nice.
I have a very important question about the battery life
i need every extra hour while am using my phone heavily
any one tested a good rom in the Continuous heavy using ?
any rom and kerenal , original or cooked .. it doesn't matter

the battery dead just in 3 hours of heavy using , it was :
" 3G always on + twitter app always on + some camera "
and everything else was off and automatic brightness and disabled fast Dormancy
and that what happened , it dead in just 3 hours !
so please tell me what the same conditions with your experiment
how long it lasts ?
how many hours it gives me with this using ?
i was about using TurkbeyRom , but i asked first maybe there's better one
any ideas ?
CheckROM v4 is very good.. Even with default settings...

how much screen on time? i got about 6hours max
I'm guessing you have a metric ass load of apps running/syncing and draining your battery whilst your phone is awake. If I keep my screen on time to ~4 hours I can get 3+ days (approaching 4) of life out of a single charge: Wifi on most of the time, data off when in Wifi range, sync off, every thing that requires syncing I've set to 1 hour intervals. I weeded out battery draining apps some time ago using Better Battery Stats. Your phone is asleep when your screen is off however, so that's good. BBS might help you narrow down processes but these may not show up under Partial Wakelocks.
I am on an extremely tiny ROM however and the same can't be expected of a stock or modified Samsung ROM. Disabling fast dormancy can drain battery depending on if your provider supports fast dormancy or not.

If you want to use Twitter and Facebook apps you'll have to accept that battery life is going to suffer a ton. Good battery life isn't a holy grail or unattainable by any means, it's all in the apps and settings.

yes i know
but as you see , must people already confused me
some says it normal , and some says something wrong !!
i know it's normal when we talk about heavy " hardcore " using
but i have some hope that i can find any solution gives me extra little hours
every hour needed really in my case !
It's not a great battery profile, but it could be explained easily by screen on time and lots of apps running in the background. I guess it's a matter of figuring out which app(s) are responsible and deciding which you can live without to at least make it through the day without being at the mercy of the nearest electrical outlet. I find I can easily make the battery suck on this phone; nature of the beast.
yup i know .. but i am very confused because people keep telling me something is wrong !
some people said they got 10 hours with heavy using like mine !
Not everyone's idea of heavy use is the same, no way battery will last 10 hours with screen almost alwasy on.
Maybe you should look into an extended or spare battery instead.

No, your battery graph is normal. Every Rom, every kernel will show this result with the usage you have, don't let people fool you otherwise.

No, impossible. You can only have around 10 hours of screen-on time while doing *nothing*, I've also accomplished that once:
While on other occasions it will look like this:
So all that BS that Rom X with kernel Y will magically improve your number of hours: no. Only thing that matters is: what's running in the background, what's being displayed on the screen (dark or light images) and if you're using lots of bandwidth.
Browsing the internet while displaying a light screen: max screen-on time of around 4 hours (so: battery will be dead in around 4 hours as well). Using the phone otherwise while displaying dark content: maybe 5 hours screen-on time or more.
All that "I have X hours of screen-on time with heavy usage!" where X>5 hours is complete B.S.
Thanx a lot , now it makes seance
now i am officially disappointed , lol
ok , what about new batteries that samsung made recently
i heard that there's some improved batteries last longer than the stock one
is it true ?
sorry for asking about that , recently i am here a lot to see what is new

My X is greater than 5.
I'd think more about grabbing a bigger capacity battery or more batteries so you can swap over to a fully charged one when you need to.
I agree with eliminating unwanted battery drain but I don't agree with not using apps we want to use.
We have an awesome phone. Enjoy it. Use what apps you want as much as you want. So you have to take 2 minutes out of your day to swap a battery who cares. Better that than having to use it like an old Nokia.

Most people report good battery stats. Give it a week and see if it settles down. Might need a few recharge cycles to level out.
As mentioned, the OS needs a few power cycles to generate its Batt Stats to give you a more accurate baseline. Also if you need your device to last all day and into the evening with no supplimental charging, you may want to look into taking certain measures to ensure your battery life is sipped and not gulped. I am not sure your level of experience or you tech knowledge, but basically anything having to do with comms is going to suck life. BT, wifi, 2g/3g/4g, and gps are what we’re talking about. You can manage these manually or use apps to do it for you such as Juice Defender and 3gWatchdog to name a couple. My office is in the bowels of the building where reception is spotty. The first week with this phone, my battery was at 40% by lunch time. This is because it was constantly searching for signal and when it did get one, it was being forced to high power to maintain it. Since I really don’t use my handset much in my office, I decided to take drastic measures to see what could be done. I installed the previous mentioned software already to keep my data use under control (came from a unlimited plan sucking down 8-12 gigs/mon on average) so with a few tweaks it was set to assist me. So when roaming my building I check it occasionally and when in my office I switch to airplane mode since I have my email in front of me and I use Google Voice to ensure all my calls find me no matter where I’m at. I arrive at work at 0700 and stay charged in on my drive to work. So at 0700 I was at 100%. I switched to AP mode after 15 minutes of typical goodmorning watercooler talk. At 1200 I looked at my Note and it read 99%. I went to lunch and opened all connections up while in our cafateria and after 45 minutes I was down 5% with comms going and lots of email and FB browsing. I’m back in my office and still at 95%. Obviously not everybody can follow the scheduled use as I laid out, but it works for me since I don’t have signal anyways and will make day much easier when I have to do lots of running and wont be plugging in untill tonight around 2300 except when commuting. I’m hoping this trend of juice sipping continues on for the rest of the day.
Screen brightness\use also is a big juice sucker. So, with the big screen on the note you need to be mindful of that, too.
Thank you for taking your time on that long informative answer!
Asides, today at school, my phone was on complete idle standby with lowest possible brightness and Wifi off (but mobile data on) and by 2:00 (6-2 so 8 hours) I'm down from 90% to 75%.
Is it defective or is what I'm getting normal?
Edit: Forgot to add I have a Tasker that disables mobile data when turning the screen off.
Edit 2: The Tasker profile is for the screen facing down, not being off.
Still, is that not a lot?

What are you complaining about those are great numbers. Losing 1% every 5 minutes means 500 minutes of screen on time, which is 7 hours and 10 minutes. Remember that's just with the screen on. With the screen off and sitting in your pocket you will lost about 1% per hour.
2g/3g/4g...each step you take the worse it is on battery. Restrict to 2g (edge) if you arnt downloading or doing anything. There's lots of toggles. What Juicedefender does is kills the connections untill you turn the screen on and I believe periodically between screen ons to pull any texts and such. The weaker the signal strength (bars) the more battery its using in order to stay connected. Try a few things and you'll be surprised at how stepping in a little to restrict its juice use will make a difference in battery life. Plus, as mentioned, give a few days to build those batt stats up, then it will give a more accurate measure of the current capacity.

So you lost about 2% an hour. Typically you should see 1% per hour. So either you were in a low signal area which caused it to use more power to find a signal, or else you last charged it with a USB charger which prevents it from going into deep sleep (known bug). Or you could have a misbehaving app.
Download CPUSpy from the market an BetterBatteryStats from XDA and see if your phone is deep sleeping and check for wakelocks.
I last charged it with the OEM Samsung charger.
Is that the problem? The reason I started this thread is because I see people reporting (yes I know) that on standby they get great battery life.

Every phone discharges differently, especially when new. The overall life is what's important as to whether it's acceptable to you or not. Give it 2-3 days of good ol fashion heavy use. A few good full charge then full discharge are good for getting a good baseline. I remember one of my phones would lose it's top 10% (100 to 90) in a matter of minutes of being unplugged, but then would be fine the rest of the day. This is what I mean by the overall being the important part. But the rogue app part could be something to look into. Aften when we get new phones we go hog wild with new apps with the "lets see what this baby can do" mentality, I say this because I am very very very guilty of it. Sometimes you get an app that malfunctions or is just straight BS. There some that open by itself. Some that you get Ppush notifications about buying ingame currency for and other shady stuff. I try to install only a couple apps a day to keep an eye on weird stuff happening.
Thanks for the replies everyone.
Chief Greek, are you seeing around my results or do you think it is simply a matter of my battery stats not being correct as you said?

I have been using my method I stated in my first reply. Here I sit about 9 hours later and my phone is at 92% with no supplimental charging.
Do you know of a way to get a 4G toggle into the dropdown menu for easy access alongside Wifi, Rotation, etc?
Those are some good stats though.
Edit-One app I do have installed is "RAM Manager" and I replaced Samsung settings with settings in app. Could that be detrimental&

Havnt played with ram manager, although used something called cachemate before. Seemed to do the trick when phone was acting goofy or very lagged out. I would wait a few days and see if it levels out. Keep screen off when you dont need to use it and if you really really want to do something about it now, install the free juice defender and see how you like it. If you like it and want more controls, upgrade to one of their pad versions.

It seems deep sleep is working. On the other picture, Alarm Clock had a wake lock of 44 minutes, is that bad?

I can go for hours in standby w/o loosing any amount. Except when I forget the work-around for the charge wakelock. I will loose several percent per hour then...

tjw - no, it doesn't look right.

I loose 1% per 20-30 minutes on standby =/ What settings do you have/how many apps do you have? Do you keep Wifi/Mobile Data on all the time? Reason being, I want to get this figured out before I root/go any further. If it is indeed my own issue, I want to to get it sorted out. Is it worth a factory reset?
Not to get off topic but are the batteries from the international version and the Att version the same? Could they be a different type or manufacturer?

I am not an expert answer on this but yes, I'd like to think so. In some cases it would not be the same (being that ATT has NFC and International does not) but considering the NFC chip is NOT in the battery, it leads me to believe that the they are the same 2600mah batteries.
So, I was just with Samsung chat agent (who probably didn't know a lot about the phone) and she said lost of 25% was normal standby. Am I the only one with this? Techntreck, you get hours on standby?

10% Battery left at this point. I started the day with 100% at 6:20am. It's 7:58pm (19:58) now. Is this bad?
