Update and FIX!
My phone is no longer draining massive amount of batt life when idle (3-5% after 7 hours of idle), android system usage is now down to 5-15% instead of 78-97% from before.
My fixes.
1. Turn off data syncing
2. Turn off wifi while on the road (so wifi doesn't constantly look for signals).
3. Clear memory
Yes, att installs a lot of bloatware that constantly update for changes.
If killing those services AND disabling data syncing doesn't help your problem, then you have a kernel problem (like myself).
If this is the case, do the following:
1. Take phone back to att and get a replacement
OR
2. Re-flash your android with the STOCK kernel found here
http://forum.xda-developers.com/showthread.php?t=1286432
OR
3. Reflash with cognition x2 (reported to solve a member's problem, I didn't try this myself).
NOTE** This will root your phone, you will NOT get the exclamation mark during boot up, but kernel counter may be at "1" after this process.
Re-flashing my phone AND applying the three tricks I mentioned above worked for me..finally my phone is no longer crippled with crappy battery life and recharging is A LOT faster now.
I must be going crazy but this sg2 is killing me. I got it from Att yesterday and the battery life has been pretty HORRIBLE. (First time android user btw).
The phone will eat up 10% of my batter life after only 90 mins of idle. I checked the battery usage and Android OS is at around 78%!!! How do I fix this problem? I downloaded OS monitor and didn't really see anything that uses a lot of CPU, except for certain files syncing from time to time (but 2-3% usage usually).
Checked with battery spy and apparently the majority of the time, the phone was hovering around 200mhz 70% of the time and not deep sleep.
It's sad to have only 1.5 hours of display time with a battery of 45% left (7 hours total time)...coming from an Iphone 3gs, this is just unacceptable. I almost flashed to the 2.3.5 firmware but noticed it's NOT compatible with ATT's version of SG2.
I see people who have a total time of 2 days AND a screen time with 3 hours with 30% battery left. I wish I can get half that!
Running on 2.3.4, can't be the infamous drainage bug right? Thought that only happens with the 2.3.3s
Wifi on, application sync on, GPS off, brightness at 25%, using live wallpaper (the windmill). No active apps on. Downloaded aim, epocrates, battery monitor, cpu spy, and os monitor..rest of the apps are stock.
Update
According to my CPU spy
For the past hour that the phone was in idle
2:20mins at 1200mhz
4:52mins at 1000mhz
8:33 at 800mhz
1:28 at 500mhz
10:11 at 200mhz
33:36 in deep sleep
Currently Android CPU usage is @ 97%, display time of 7mins(2%)
2h 30mins since last charge (97% charge)..current power is 79%. Did nothing but idling and checking battery life.
So...that's 30 mins out of the hour in which my idling cellphone was hacking the pentagon....
Also the cellphone is a tiny bit warm to the touch (not cold)
I have 35% battery life remaining and have been unplugged for nearly 11 hours. This is significantly better than what I was getting with a Thunderbolt on Verizon, where I was needing to charge after about six hours of use. 11 hours and 35% remaining isn't the best in the world, but it's only been two days. The phone needs a few days to charge and discharge to determine true battery stats and will probably get better.
Being that this is your first Android battery life will not seem great but let it settle in for a few days it should get better.

Used Nexus S, LG Thrill, Samsung Focus, Infuse, This is the best Android phone for battery. I have 40% left with normal use (emails, calls, music, read news) at the end of the day. Huraaaaa

If you only got the phone yesterday, its way to early to make any judgments on battery life. Battery needs at least 3-5 days to settle in and build consistent battery stats.
Also, what are you settings? Auto Brightness, Bluetooth, GPS, auto syn(exchange emal, gmail, facebook, etc). If your not using these, they should be OFF. It's easy to manually refresh email, etc.
I've seen some people reporting very high Android OS(over 50%) but still getting solid battery life.
I'm at 1hr display time, heavy texting. 72% left, been unplugged for 12hrs
no people what this guy is talking about is the android os bug. i have it too. hopefully an upgrade or different rom will fix it. my phone has been unplugged 11 hours with only 1 1/2 hour display but android os has ran for 52 minutes and now im at 32% battery life. once this bug gets worked out the battery life will be amazing.
I don't think that there is an android OS bug. My android OS shows as being 42% with 13hrs of moderate use and I am still at 67% battery remaining. This is by far the best battery use I have ever experienced on an android device! My cappy would not even come close to this performance and this is on stock ROM and kernel.

I'm very happy with mine, this was the first total drain on a new battery so I know it will only get better.
Total time: 18hr 25min
Display time: 4hr 48min
I think it's the system os, not the hardware. There were a few times when the battery didn't discharge itself at 7%/hour (had it idle for 3 hours and it went down like 2%).
And yes, everything is turned off except the sync app data and wifi. There's no option to turn off 4g btw. It's just weird how sometimes it's in this mode of power drainage, and then sometimes it doesn't drain much..but most of the time, it's draining.
I seriously doubt the phone can only run 2.5 hours worth of heavy usage or 12 hours of standby (it should last days!). If this is "normal" for android, then maybe I should have a visit back to att and exchange for an iphone (and I really don't to!)

I agree - as I said in the Android OS drain thread, even in "good" situations, Android OS displays way high on our systems. I think it's a reporting bug.
I dropped 2% in 5.5 hours completely idle (sitting on my shelf) last night - Android OS was at over 60%. It seems that so far for me, the higher it is, the better my battery life is.
I drop around 15-20% in 9 hours of being mostly idle at my desk at work - it's a weak-signal location so the radio eats much more battery.
One thing is that unlike first-generation GalaxyS devices and interim ones like the Infuse, the GS2 has a coulomb-counter type of battery gauge. This type of gauge sometimes needs to be calibrated with multiple charge/discharge cycles or it will misreport battery state of charge. (However, when calibrated, it's much more accurate.)
Edit: I do have some power management tweaks in the kernel I'm running, but they don't make that much off a difference except in some high-drain corner cases in my experience. I'll be releasing it sometime later this week depending on how well these antibiotics do their job.
Do i need to install a battery app to see the percentage? or we have a way?
Install this app:

If you see "DataTracker-FD" or "Fast Dormancy" as the top wake lock, go into dialer
dial *#*#9900#*#*
disable Fast Dormancy (FD).
By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.

That applies to the I9100.
As far as I can tell, the I777 has FD disabled by default. (This may change once I9100 ROM ports start showing up)
Okay, charged my battery to 97%(I got a beep saying it's fully charged). Idled for the past 2 hours and 22 mins. Battery is at 86%.
According to the battery, my screen account for 2%, and the android system accounts for 97%.
This is a stock phone guys, I have no apps installed!

Just search up "battery indicator" in the Market and you'll get a few to choose from.
I too got mine yesterday and started tinkering around with installing apps and such to test out all functions before I rooted it and move onto cm7 most likely. The 1 things I noticed was that the battery was NOT completely full when it was first turned on at the store so once it got a little lower after playing with it I charged it up overnight. Today the battery was WAY BETTER and was not dead yet. I have been using it NON STOP today, rebooting it, testing it, trying to root it, rebooting some more, some time using tango to test it out, watched a Netflix movie, pretty much taking full advantage of it all day. I finally decided to charge it up and use my Captivate a bit. I didn't keep track of usage and times today but I KNOW it lasted a WAY LONGER time with all I was doing with it than my Cappy. Tomorrow I will check more out possibly before putting on a rom.
So LOOOONNNNGGGG STORY short make sure you charge it up once you get it before messing with it too much and then it will LAST LONGER.

After two nights of completely draining then recharging the battery to full, the battery has gotten significantly better. I'm trying to drain it again before I go to bed tonight but I don't think I'll make it.
I played the entirety of Toy Story 3 on max brightness, and only burned 20% of the battery!
Usually, on weekends, or holidays, I use my phone for Angry Birds, many other games, music, etc for a long period of time. Today I managed to get about 5 hours use until the battery got to 30%.
I'm not sure whether or not this is good or bad and so I'm wondering; how many hours do you get out of it, in relation to being a heavy user, medium user or light user?
Thanks
about 5/6 hours max
With normal usage 24-30 hrs. Wth heavy use, 8-10 hrs.

always have 3g on and im quite sure i listen to music for 7 hours at least while im at my office...and by the end of the day i have like 20%
10 days and still going
With all data disabled most of the time, almost unused, but still connected to the GSM network, mine is now at more than 10 days (and I think it wasn't even fully charged at the start of this period). This is with stock ROM, Apex launcher, almost no other custom apps.
It's hard to have an effeicient answer since it depends on many factors : the way you use your phone, your ROM , Kernel and all setting stuffs etc ... . And even with same settings , two SGS II can have a totaly different battery drain. So, you can compare but it wont realy be so efficient .
Anyway , for me with a usual use : almost 2d and with heavy use about 16-24 h. I m on Wanamlite 10.6 with last Siyah V3.0 Kernel.
At weekends 5 hours max weekdaus prob 8-9 hours
Mod or Die
Plenty of hourly syncing and light use....
Stock rooted KL1 + LPR radio
I have tried 3 different ROMs and with the last ICS ROM i had 8-9 hours with heavy use of 3G/Bluetooth/sync ... and of course it's depends of what apps (games ) i use among the day ...
awesome how some users get 24 hours with a single battery charge.
When I use my S2 as a normal phone, about 20 hours.
But with heaving usage and gaming (which I do pretty much) probably between 6 or 8 hours also.

Woah :O Doesnt matter had "10days" :O
i guess screen on time is more important than overall battery time. I Used to get 4hr screen on time with a full day usage which is quite good for me and i think its average.

+1 Agreed here are some on my screen shots.
Usually prefer to watch youtube video's through browser So flash is must & it is a nice battery drainer too.Plus 4 hours of non-music playback !
Brightness - 20%
When i use gprs heavily it is very less!
Normal use may last a day!
Playing games also burns the battery pretty fast!
I have a Superatmos ROM installed in my Galaxy SII i9100G and I get around 30 to 35 hours of standby time with normal to low use. I do however browse the internet over WiFi some 4 hours a day.
I am quite happy with the performance of my phone.
So far its three months but its like Triggers Broom .
jje
I got a battery app installed which shows % in the top bar. It stays at 100% for a while but when it starts draining with the screen on I lose about 1% every 1-2 minutes, I think its somewhere in between, if I am taxing the cpu it more frequeent than every minute, this would give me about 2-3 hours usage which seems extremely low.
Brightness is min.
wifi/3g off.
auto sync off.
accuweather is installed (mentioned as it has a service running).
I get the drain simpley from doing things like scrolloing app drawer and checking sms.
With screen off in sleep mode battery drain is ok less than 5% in 12 hours. I have this issue confirmed on 2 different batteries.
If this is normal fine, I just want to compare to others on this.
I used to get around 1 day for heavy use ( like wifi, games, etc.) and 1.5 to 2 days for moderate use Which ROM are you using ??
Cm7 based roms use more battery than stock, cuz also their performance is a lot better.
Use uot Kitchen to get the % battery instead of an app.
Also the launcher u use affects battery. ie Go launcher drains plenty of battery.
If you can't squeeze a day's worth of battery from ur phone ur probably using it too much (how much does a laptop last on battery, seriously!)

you mean a day of constant use screen on or would there be periods of it sleeping?
My phone lasts more than a day mostly 3-5 days but thats mainly because its idle most of the time. However I plan to transfer some tasks to it and it seems I will need to keep the charger in during the day.
Compared to stock CM I think isnt too bad, the drain was also bad on stock with the screen on and during calls but the only reason I specified CM is that I didnt have the % meter on my stock rom which means I dont have the same comparison.
My current rom is vo-1's 30 may build. I had bugs on official nightly that vo-1's resolved (including force reboot when using market) so is the reason I am using it.
Incidently my laptop drains its battery slower than my android.
Why I read that so many use thier phones like 2 days, and I can't even get a 12 hours fair use.
I use 2G (3g drains my battery really quick), some whatsapp, some FB and some calls. Music it's only in the morning on my way to work.
I've buy a new battery from ebay, but, it's the same. Using CM 7.1 rom "The End 4.0"
yeah my hunch seems right that it wasnt overall much diff to stock (that also drained superfast when screen on). IN fact during sleep it seems improved over stock.
I am over 4 days at the moment with 35% charge left. mostly sleep. It lost 3% during the time it took me to fetch the below stats. Note that calls like my earlier hunch as well seem to drain battery far more than display.
4 days 8 hours 38% left
display on 40mins used 4%
voice calls on 1hr 5mins used 33%
mobile standby 41% 4hrs 8 mins
phone idle 4days 7hrs 23%

Surely, you're not using WhatsApp, Facebook Messenger, handling e-mails or any of the like. If you're just using the SGA like a normal phone, OF COURSE it can give you that kind of performance. If I'm wrong, please correct me.

yeah sadly it seems noone has a comparison that I need.
Which is time needed for 1% usage whilst screen is on.
This isnt on stock tho the phone is on CM7.2 vo-1 build.
From what I see the battery life is around the same as stock.
Now I am over 5 days with 17% left. Just did a phone call and it stayed at 17%. When below 20% on stock the phone was unuseable.

my quad core s3 is a no-contract phone . uses pre-paid card. so there is no 3g/4g. i get around 4 hours screen on time with power saving mode on with juice defender on. i find that gaming time in this phone is awful. in the iphone 4, i get 5 hours 3d gaming time. now i dont even get 4 hours 2d gaming time! is this normal with the s3? but stll this is a fantastic phone. without gaming i get 6 hours screen on time. just would like to know if you get the same with gaming. iphone 5 seems to have a really good battery with 8h screen on time.
Make sure you disable wcdma in network settings.... your phone probably searching for a 3g signal and failing.

Get rid of juice defender and turn off power save mode.
Also 8 hours screen on time for ip5 is questionable, these are the same people that said 8 hours 3g use and 10 hours LTE. As everyone knows, LTE uses more power than 3g.
Their numbers are lies/exaggerated.
If you want the iPhone so badly then you know what you need to do.

I too have Power Saving Mode turned on, and manually adjust the brightness (it's always set to the lowest setting).
I have WiFi turned on the entire time that I'm home, and 3G when I'm out.
Auto Sync is on the entire time, because I want to be able to know when I get an incoming email.
That's pretty much it.
I am not able to come close to 4 hours of screen time, before my battery reaches 5-10%. Cell Standby accounts for the most battery usage.
Any pointers/tips?
P.S. Phone not rooted.
Do you have Viber? If yes there is a bug in the latest update that's keeping the proximity sensor on and draining the battery. 4 hours screen on time with battery save mode is really bad. There's probably some app draining the battery.
Ps. Ip5 battery life is a lie as usual, people who have it and actually use it say battery is actually quite bad. Also on the ios stats you don't have 'screen on' time report, but 'usage' time that is a lot more stuff than just screen on time. People who say the have 8 hours are probably just reading the usage time.

Yep; I do use Viber. I think you're right. Ever since I got the latest Viber update, the battery seems to die off sooner.
Should I uninstall and check?
How can I check what rogue app is eating into the battery?
Well. i hate the iphone 5! no i dont have viber. juice defender shows me battery improved by 1.8x. i have auto sync off and power save on. i have disabled mobile data. and i realised i am just expecting too much! i was surfing the stock browser on wifi for 45 min and my phone went from 39% to 34%. guess thats okay.
Viber just fixed the proximity sensor issue; hope this resolves the battery drain issue.
BTW, what is the normal hourly battery drain percentage?
You can install an app called 'betterbatterystats' (very counterintuitive name!) to see what exactly is eating your battery, it takes a while to figure out how it works but it is very usefull!
Google location services in maps and Google now (if you are on jelly bean) drain quite a bit of battery and basically anything running on the background. Obviously you just deactivate what you don't need!
What about the iphone4 and SGS3 screen size ...every mm more=more power

Three days ago, I flashed stock ICS (with wipe). I wanted to test the battery life.
Screen On time was a little under 4 hours.
I spent just a little over 2 hours on the phone.
Wifi was on/off intermittently.
Around 15 minutes of gaming.
The phone lasted 1 day and 20 hours.
That, in my opinion, is really, really good.

You can easily go for 2 days with this phone and normal usage if you turn off or use airplane mode at night. But I never do because the phone is so cool that I use it all the time! I charge at night, still I never get to 0% at the end of the day.
anyone else can post their experience with battery life?

battery life on this babe is good enough for me!
I get around 21-26 hours of standby time and screen on time ranging from at least 5 hours to 6.5 hours. When I don't browse much and just use the Adobe Reader I b get around 7 Hours plus a few minutes.
I switch on power saving mode when the battery drops below 30% and my brightness is set on auto and I'm connected to a 2g network. No gaming. I generally browse the Web for an hours , listen to music for a few minutes and then read on the Adobe Reader.
Auto sync is switched on at all times.
Post your battery life here and say witch L9 you have. And give the most details if you can
(I will get this phone next week want to see what you guys get out of this phone)
And i didnt see any thread like this. So i start one.
PEOPLE plz post also screen on time!!
edit have the phone. and it has good battery life will post mine soon also.
Battery life is very good, this includes mainly internet browsing with wi-fi and 1-1.5 hours of gaming, brightness always at 50%.
My cpu is undervolted a lot, for example I give only 860mv for 1000mhz, hotplug governor. I have 25% battery left so I could have about 4:30 hours of screen on time using the full battery charge.

My cpu is undervolted a lot, for example I give only 860mv for 1000mhz, hotplug governor. I have 25% battery left so I could have about 4:30 hours of screen on time using the full battery charge.

I made massive overclock but it's perfectly stable for 7 days, here more about my settings:

Unfortunately I have not a 3g plan but I think it should also be good because L9 has a very efficient modem (talk time is one of the best, see gsmarena battery tests).

P769 battery life
I do not have a screenshot, but I have nearly gone 72 hours on one charge. I am using a rooted P769 v10g with most of the bloatware frozen. Wi-if, auto sync, and screen brightness at 50% during that time.

Lol. Granted it was a very inactive time for my phone. I just thought that it was pretty amazing for the phone to make it that long before needing another charge. On average I only have to charge the phone every other day.
Re: Post your Battery Life. With screen shot if posible
This is about average for me. Sometimes as much as three days, but never less than 30 hours.

Without screen on time other stats are unuseful.

carter07 is right forgot to say, post screen on time (so we can see if you used your phone alot or not.)

your guys battery sounds great;
mine only lasts bit more than one day
For some reason, my battery life has gotten worse than when the image was taken. I am insane, mental, and deranged about battery life so I will have more specific percentages soon. I have tried ending anything I suspected was using the battery to save battery life. When the phone is charging, I even take the back cover off my phone to disperse the heat from the battery. Welcome to the most useless and pathetic obsession in existence.
As you can see, the screen takes up the vast majority of battery life, due to being at 50% brightness. Any lower, and I would have to bring my own flashlight. I turn off wireless unless I use the Internet. One charge ranges from 3 to 5 days, depending on how bored I am in school and how much Fruit Ninja/Temple Run I play.
Here I am again with more battery life measurements. Playing Fruit Ninja causes the battery to drain 1% every 3 minutes or so. On the other hand, leaving the phone on sleep mode causes 1% to drain in about 5 hours. Also attached are app percentage power usages to give a sense of what is using up all the battery.

These are my results with above average use(wifi or 3g always on,sync every hour,a little bit of subway surf...)
5h ?? what brightness u were using ?? 30% ? this is cool
How can your battery last so long?? Mine has never lasted more than one day, never!
The screen is always on 50% brightness,except when battery goes under 20 then i set it to 25 %... The screen on is never under 4 h... With heavy use,battery holds through the day easy... I'm very satisfied with the battery life of my L9..
