I know this topic is always repeated but I fly I should havr made a thread anyway. This morning, in 15 minutes of web browsing, I lost 3% battery. In 10 minutes, I lost 2%, so it seems to be progressive. I just got this phone Friday.
That can't be normal, is it? I don't want to return it but I will if its a bartery issue. Could it be as simple as buying a new battery?

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.
Sent from my SAMSUNG-SGH-I717 using xda premium
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&
Sent from my SAMSUNG-SGH-I717 using xda premium
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.

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?

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.

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.

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.
I absolutely love everything about my first Android phone, the hardware, software, apps...it's all good...except the battery life. I've tried most everything I've read here to try and maximize it, and I'm still having to break out the charger to get me through the evening.
Coming from BlackBerry, I've been used to having battery life exceeding two days...not that I ever needed to last that long, I always charge each night anyways. I merely want to be able to make it to bedtime each night without having to charge the phone, without having to cripple the features I love about it, and without having to be overly wary of my usage.
Is this dream possible with this, or any Android device?
I've tried the stock ROM, now on UnNamed...tried Juice Defender (got rid of it), SetCPU, Screebl, using Llama to shut off wireless when away from home or work, brightness down low (shame with such a beautiful screen)...and I still average around 7% an hour drain. CPUspy tells me I spend 60% of the time in deep sleep and 15% at 200mhz.
I don't really know what else to try, I want so badly to keep this phone, but don't want to significantly compromise the way I'm used to using my mobile device. I don't play games, I don't watch videos, I use my phone as an information and communications tool...and from that standpoint, this phone is simply awesome, if it would just get me through the day.
I have one week left to try and resolve this...what should be my next step?
It does sound like you're having unusual low battery life, my phone says that it's been 2 days 6 hours since my last charge and I'm still at 30%. If I were you, I would go and try to exchange it and see if maybe they give a little extra time to test out the phone.
See I would be ecstatic with 30% remaining after just one full day...I take the phone off the charger at around 7am, and would prefer not to put it back on a charge until 11pm or later.
I got it from Amazon Wireless, so I'll have to give them a call and see what they say about an exchange...you always run the risk of getting a device with an issue though, and this one is perfect otherwise...
Best of luck resolving this man!
It seems that the drain is only really happening when the screen is on...I can let it sit for awhile, and the battery meter doesn't budge...but I pick it up and start using it and you can practically watch it dropping...
Turn your data off when you're not using it
Sent from my SAMSUNG-SGH-I777 using Tapatalk
So from about 7:30 this morning until around 12:45pm, I dropped about 13%...which is around 2.5% an hour, something I can live with. Although that was with almost no use, screen off most of the time. In the last 45 minutes, I've been using the phone, reading emails, screen on much more, and it's dropped 8% more in just that 45 min period. My screen brightness is about 25%.
That can't be normal, right?
EDIT: Ya know, I'm just going to shut my mouth and enjoy my phone. I put it on the charger at work for the last 30 minutes of my workday today, and I'm at 80% at 8pm...I'm good with that. I'll pick up a couple spare batteries, and with chargers at work and home, I'm all good. I'll keep it as bright as I want it, sync data as often as I want, leave the CPU speed alone, and quit looking at the battery gauge...when I do that, it's a fricken awesome phone.
I was having this problem also, I use juice defender pro, and setcpu. I have juice set up to kill all connections when the phone is sleeping and set it up to where it syncs my facebook/emails every 2hrs, in setcpu you can create custom profiles that allow you to underclock your cpu when its sleeping, charging, certain times of the day/night. Im looking at my phone now and im at 1 day 0h 16 minutes with over half left. If you need some help setting up custom profiles and configuring juice (I recommend redownloading it again.) Shoot me a pm and ill see if I can help you. Good luck
I didn't want to compromise how I use my phone either. Most days I take my phone off the charger at about 7:30. By about the time I come back from lunch 1ish, it usually above 50%, but right around there. I generally plug it in at work for a few hours and generally can get it back to 90+ before going home. The day includes generally 3-4 hours pandora, so I figure that's par for the course. When I had my captivate doing the same thing it was almost dead by noon.
I think I might just be able to make it all day on a singles charge with what I consider heavy use, but its nice never seeing my battery drop below 40. Here's my weekly use, you can see the pattern of small drain, recharge, drain, charge overnight.

Everytime I think my battery is draining too fast I think back to how long ago the power in my hands wasn't in a computer tower, and I calm down. My phone is an extension of my hand, always being used, I don't expect my friend to starve, and don't feel unreasonable to let him snack mid-day.
For what its worth I am on UnNamed. I used S8 and did not see the giant jump in battery a lot of people claimed, I felt it was the same. I wasn't on stock long enough to really tell. But, I feel you need a week or more to really know, and I didn't last that long on stock.

What is your screen timeout set at? Anything more than 30 seconds will drain battery excessively. Also, do you keep your screen on when listening to Pandora, or while charging the phone? Those are also a waste of battery.
2.5% per hour when idle its not bad, and losing 8% in 45 minutes with the display on is actually pretty good...
I leave the screen timeout on 1 minute, its too frustrating to me when I am trying to read a webpage or thread and it times out. Maybe I am a slow reader, LOL. 45 seconds would probably work for me, but its not an option in these ROMs. I leave my screen brightness to automatic, and turn off my screen as soon as I start pandora. I do use Bluetooth to listen to pandora, so I bet that doesn't help. I also listen to audiobooks over Bluetooth in the car to and from work. But I did all the same stuff with my captivate. I have started using wifi when at home, but haven't seen a battery impact for that.
Sent from my Galaxy S II (i777)
not surprising at all to see your battery drain like that when you use bluetooth so extensively. nothing wrong with bluetooth, but it is definitely going to use up your battery faster - there is a huge difference in battery drain between a regular voice call made with the handset, and a voice call of the same amount of time made in my car via bluetooth - i don't have exact statistics, but i'd say about double the drain. same thing between a wireless bluetooth headset, and a pair of wired headphones.
sounds like you have solved your problem with multiple chargers, but if you wanted to avoid charging in the middle of the day, switching to a wired pair of headphones when listening to all of your pandora would almost certainly do the trick.
Wow, I didn't realize it was so much. I have headphones in my desk at work for computer trainings, but never use them on my phone. Plus I could plug my phone into my car's radio go play over the speakers. I think its a convienience thing more than anything else, not having to unplug for the car when I get to work, nit taking the headphones out to pick up something at the printer.
As you said another charger is a good fix, something I never need on weekends, but I ways attributed that to pandora more than Bluetooth. Definately food for thought. Thanks.

As far as the screen timeout, I use Screebl and it works great. It senses the position of the phone to know when it's being used and keeps the screen on, then also can tell when the phone has been set down and turns the screen off within seconds. You can manually set the angles and positions so it also works fine when you're reading in bed. Helps with both keeping the screen on for those long emails as well as shutting it down quickly to save a little battery life.
Without a doubt, it's the screen being on that is the primary battery killer on my phone...when it sits idle, regardless of how often data is being used, I'm under 2% per hour drain. When the screen is on, you can practically watch the needle go down, it's crazy.
I do use SetCPU to drop the CPU to 200-500mhz when the screen is off, and to drop to 200-800 when it gets below 30%...aside from that, I'm done trying to optimize. I want to have my email and other notifications come in when they were sent, not an hour or two later. I want to see the great screen in the daylight, not a dimmed version. This is why I bought the phone. All that power requires some juice, so I'm going to make sure I've got extra juice on tap.

I didn't want to compromise how I use my phone either. Most days I take my phone off the charger at about 7:30. By about the time I come back from lunch 1ish, it usually above 50%, but right around there. I generally plug it in at work for a few hours and generally can get it back to 90+ before going home. The day includes generally 3-4 hours pandora, so I figure that's par for the course. When I had my captivate doing the same thing it was almost dead by noon.
I think I might just be able to make it all day on a singles charge with what I consider heavy use, but its nice never seeing my battery drop below 40. Here's my weekly use, you can see the pattern of small drain, recharge, drain, charge overnight.
Everytime I think my battery is draining too fast I think back to how long ago the power in my hands wasn't in a computer tower, and I calm down. My phone is an extension of my hand, always being used, I don't expect my friend to starve, and don't feel unreasonable to let him snack mid-day.
For what its worth I am on UnNamed. I used S8 and did not see the giant jump in battery a lot of people claimed, I felt it was the same. I wasn't on stock long enough to really tell. But, I feel you need a week or more to really know, and I didn't last that long on stock.

What is that app you're using?
The SGS II has power drain issues as well? I had the captivate and I could turn it on and watch the battery drain. I'm on Atrix 2 right now and I have zero issues with the battery. Best buy has dropped the price of the SGS II and it's really tempting to switch. Hmm what to do... What to do...
I picked up an Atrix 2 from Best Buy off contract last weekend so I could compare side-by-side with my SGS2, I really wanted the notification LED...but I took the A2 back yesterday. Improved battery life and the weak notification LED couldn't overcome the stark disadvantage in performance and screen quality (in my opinion). Laggy web browser and menu scrolling in comparison and an overly backlit looking screen with little contrast...although if I hadn't already had a couple weeks with the SGS2, I'd have probably been fine with it.
Everyone has different experiences with battery life depending on how they use their phone, you should grab the SGS2 and do a comparison and see what works best for you. Battery life has dropped down my priority list as of late, since I'm using the phone so much more now for every little thing (becasue it's so damn gorgeous), I have to expect to use up some juice.
Yeah I had to install miren browser, go Launcher, and handecnt SMS to change the color of the LED colors. Loving the phone and hopefully we will get an unlocked boot loader. SGS was really easy to root, flash, and OC. Still a bit pissed at AT&T for releasing another SGS II, no reason for doing that. I have a couple of weeks to kick the thought around. If its looking bleak for us A2 users then I'll jump on over to the OG SGS II lol. Screw the skypocketrocketshipboat.

try screebly, that will let you set you timetout to 15s, whiel avoiding the issue you speak of above.
As the title says I haven't seen anyone actually test the battery for a couple days, it's usually review and move on.
So how is it?
Well it hasn't been mentioned so it probably isn't worse than we expect it to be.
Also interested to know. Of course since this will be the first few days people have it, they'll be using it a ton so it may not be the best estimate on battery life but I would love to know an idea of how much to expect.
They haven't had time to calabrate yet.

7 hours of heavy use isn't bad. So idling with 4G off probably isn't terrible then. That is what I am most concerned about. Hopefully we will get kernel source and just get some undervolt going.

yeah not to mention that after you root you can flash leaner kernels and ROM's. But we'll have to wait for development to pick up, I really hope we see some good developers here.
So right now it's 1am and I took the phone off of the charger at 8:21 with 85% battery life. It is now at 47% with some steady texting, exchange activesync, some web browsing, and a 7 minute video all on 4g. I'm not sure what to make of that but it seems decent.

DAMMIT I WANT!!! 3 more days...
I don't know that I've charged it fully since I got it. It was close to fully charged before I went to a wedding tonight. Lasted all 6 hours or so I was there, but was tuckering out (~20%) by the time I left. But I did spend a bit of time playing with the phone. And 4G was on the whole time. And I turned live wallpaper on, played with my weather and clock widgets, tried to get a wifi connection that wouldn't work, browsed the web a bit.
I recharged on the way home to about 50%, and sitting around playing with it for the last hour to 1.5 hours, it's still at 40%.
If it makes you feel any better, the biggest battery hog was the display, BY FAR. Like 80-something percent to the <20% combined for the other functions. I'll try and remember to post my impressions from my first "normal" day of use tomorrow and let you know how the battery fairs.

I got mine yesterday and I can say it is about 25-30% better than a rooted thunderbolt....My logic says once rooted we will get really good battery life.
I am a heavy user and I can say I turned off fast boot and bump charged it 3 times on Thursday night. I gave it a heavy use all day on Friday.
Took it off the charger at 10 am around 8 pm I was on 35%. So that was 10 hours of heavy use and still had 35% left. If I was using the rooted bolt I would have been dead around 5:30 and a stock bolt...even sooner.
hope all these battery estimates are true, sounds like this will be my next phone!
Took it off the charger at about 11am today... Was close to 100%, maybe 95%. Just hooked it up to charge about 10 minutes ago (so off charger completely for ~10 hours). It had ~10% battery life left when I hooked it up.
Had Wifi and/or 4G on the entire day, including an hour and a half in a bad service area, where it fought for a bit to find service until I logged into the wifi network. Played about 1 hour worth of Pandora on high quality setting. A couple minutes of 4G Youtube. Tons of tinkering with games and downloading apps and playing around. Screen brightness was set to something like 30%. live wallpaper enabled. Weather and clock widget enabled. Data tracking widget enabled. Did a few seconds of video Skype too. I would say it was consistent use all day, but not necessarily heavy for most of the day.
EDIT: I forgot. One short phone call. I'm sort of a bad guinea pig for battery life on a phone because I really don't make a lot of phone calls. Consider my use representative of someone who uses data during his commute and for texting/games/forum/app usage.

Bad/No service areas will kill a battery so fast. My office is in a windowless reinforced concrete room inside a reinforced windowless room inside a reinforced building. (Yo dawg)
I get no service at all. If I leave the 3g on, phone won't make it past 5 hours. Turn the 3G/WiFi off and battery percent goes down a few points.
I need one!!!
Kellex over a Droid-Life has gotten just over 10 hours of normal usage (all in 4G) for the past couple of days. He also stated he is not a heavy user by any means.

Battery - Caution
I remain interested in the phone but undecided due to some really bad hardware failures I have on my Dinc.
While I am very interested in battery life like everyone else, please everyone keep in mind that "how is the battery" is as personal a question as "which radio is the best one to use."
There is no way one person can truly tell you how the battery will be for you. If you sit in an interior office without wifi, and have sync contacts and facebook set for every hour, that ALONE will cause a drain that may not be comparable.

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...

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.

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

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.
I've noticed with Wi-Fi on, I always lose 1% or a bit more per hour, just idle. On 3G, it's a bit less than 1% an hour.
I'm running the latest Jelly Bean stock official firmware (DLJ4).
I have good battery while the screen is on (1% every 4-5 minutes while browsing the internet on WiFi), but this idle battery drain is a bit too much...
I have Facebook setup, but not syncing, and I have most of the notifications disabled.
For my Google account, I have Gmail, Calendar, Contacts, and Internet set to sync.

Screen was on for 1min and I received a call which I did not pick up.
BetterBatteryStats did not show any kernel wakelocks (although on previous days I did see wlan_rx_wake, l2hsic, and a few others, but none today).
I have seen all over the forums that some people are getting a 24 hours of battery life with 5 hours of screen on time, with Wi-Fi on all day. The best I can get with a whole day is 3-4 hours of screen on (brightness at 40% or lower).

Looks normal, Gmail woke up to check mail 20X over the cell network while it was sleeping?
Was the phone in a good signal location?
Reason I use Wi-Fi when possible at home. CDMA is 20% signal here, GSM 90%. Perhaps your in the same situation. It is idle in GSM mode, wakes up to check mail notices it can go faster and wastes power renegotiating a faster connection?
That could easily waste power...
If so set to GSM mode, with Wi-Fi on (if screen is on) and turn cell data off.
If your signal is good, you can forget about using only GSM and just do the rest.
Not sure what else it could be, feels like cell signal IMHO. It looks high in the usage chart too, unless you made a few calls..

I lose about 20 - 25 percent per night when Wi-Fi is on. When Wi-Fi is off almost no battery loss... See the attachment for a log. I'm wondering what's wrong... So I would say that the TS is lucky to be losing only a few percent per night!
Battery drainage looks normal to me. Your wifi was also on for almost the entire time. You could use an app like Juice Defender or Tasker to schedule times to turn on wifi for syncing. That could help decrease time wifi would be on, thus saving some battery life.

It's not normal at all. I've seen others with better idle time than me, leaving Wi-Fi on the whole time. Also, my phone drains less battery while on 3G. That makes no sense.
And apps like Juice Defender shouldn't be required. It cripples the phone of a feature: background data. I use Google Voice to text and prefer my messages to come instantly instead of every 15 minutes.

Reason I use Wi-Fi when possible at home. CDMA is 20% signal here, GSM 90%. Perhaps your in the same situation. It is idle in GSM mode, wakes up to check mail notices it can go faster and wastes power renegotiating a faster connection?
That could easily waste power...
If so set to GSM mode, with Wi-Fi on (if screen is on) and turn cell data off.
If your signal is good, you can forget about using only GSM and just do the rest.
Not sure what else it could be, feels like cell signal IMHO. It looks high in the usage chart too, unless you made a few calls..

I was on Wi-Fi the whole time, so it wasn't using the cell network (3G).
As you can see from the battery graph screenshot, I was mostly in a good location. The phone was in one spot on my table the whole time, where it switches between 3 and 4 bars every now and then. I didn't make any calls but I did receive one (didn't answer it) right before I took the screenshots.

Oh that is reasonable. This phone can last that long nonstop or close to nonstop as you did.
But my problem is idle time

38% cell idle omg its like having a fuel leak... Maybe you have apps wid ads running in the background... Better delete those unwanted ads... Or buy a pro version no ads.. Y not consider factory reset just be sure u had them backed up.... Im cell standby is only 2 %

I have never heard of ads running in the background... and I had all apps closed so nothing was running to drain the battery.
I've done factory resets several times, so I suppose it's either the kernel or an app doing this... but the apps I use are very common apps and I don't sync much :L
Avast shall halt anything misbehaving, maybe worth a try? Only other thing worth trying before a factory reset is installing Watchdog task manager.
Set it up so it monitors system level tasks!
Something might only be awake for a few seconds in battery stats, but it might be running at 100% system load.
Watchdog shall catch it!

My phone always drop like about 25% when I sleep with Wifi on too. Wifi seems to eat up the battery a lot recently.... I9300XXDLJ4 with Siyah 1.7rc1....
I'm the same with WiFi on and seems plenty of others are too. If I charge phone to full and then disconnect charger, with WiFi on I get a drain of 4.3%per hour, with WiFi off its around 1%. I am now leaving WiFi on all the time but changing the option to always leave WiFi on when sleeping to never and it's middle ground. There are far to many people moaning about this to be a coincidence. I am on stock latest jb and performed full wipe and reset and no difference. Ics had better standby time with WiFi on, fact!

Same here yesterday I tested with full charge and with nonstop usage I was able to get 6hrs 8min with 21% percent battery left, however my battery drains quickly in standby mode. In 6 to 7hrs I loose about 20% to 34% when sleeping.
I have more drainage issue....

I see you're not on Wi-Fi a lot; are you on 3G or 4G?
4-5h screen on time with 3G/4G is the best you can get in a typical day.
