How much screen on time did you have? how long has it been since you flashed your current set up?

sorry forgot that shot....i rooted and flashed on either Sunday or Monday this week.....now i do use bluetooth for work so i'm thinking that kills the battery big time....
That is kind of good battery life considering you got almost four hours of screen on time. If your really worried then you should get one of the 3500 mah batteries. I have this one http://forum.xda-developers.com/showthread.php?p=21589969. This battery gets me through at least a day and a half of heavy usage, and it works great for the price.
yeah i wasn't sure...i always keep reading about people getting 1.5-2 days on a battery...it's a new toy so hopefully when the excitement wears off that screen won't be on so much
That's exactly what will happen. You have new phone syndrome. I did too, when I first got my Galaxy S2. Except that I, unlike you, was running stock unrooted, and my battery life was more like 8 hours. I'm now running stock rooted with Entropy's kernel, plus I don't use my phone as much, and I get between 15 and 20 hours.
Sent from my SAMSUNG-SGH-I777 using xda premium
Yeah...with almost 4 hours screen on, and mostly on cell data (assumption based on your 2.x hours of wifi on) that isn't too horrible. Your total awake time is about an hour more than screen on, so assuming you had phone calls, music playing, or some other screen off background task to account for some of that, you're doing pretty good...

LOL so I'm guessing the best way to really conserve battery is to keep the screen off. Just outta curiousity (which I will test tonight after full charge) what is an acceptable drop rate when phone is fully asleep for say 8 hours or so. Like what 1-2% an hour?

I think the best I have seen reported is 0.5% per hour. Mine on wifi has been as good as about 0.8% per hour, but usually a little over 1%.

2%/hour idle drain I consider bad - that's why I haven't released a kernel since 1/2/2012 - I have a power management regression that pushes drain to a bit over 2%/hour when connected to wifi.
I strive for 0.5%/hour and get very close to that frequently when in a good signal area. In a weak signal area (like at my desk at work), it's around 1%/hour.
4.5%/hour or so is the idle drain you'll get if the phone is unable to enter deep sleep.

I went to bed with the thing charged to 100%, wake up 8hrs later, not having used it once and its at 50%... okay, whatever, I guess it was about 8 hours...
So I charge it to 80% then go work-out for about maybe 2 hours and when I'm done the SOB is at 40%- I DIDN'T TOUCH IT THE WHOLE TIME! I DON'T THINK IT EVEN CHARGES THAT FAST! I don't care if it was searching for signal the whole time, which it shouldn't have, WTF?!
Other anecdotal stories: I'm fanatical about battery life and always charge it full before going out for the night or something and I'm usually lucky to make it to bar close, a total time span of MAYBE 5 hours. How is this even possible?! The damn thing is supposed to have a 10 hour talk time?! Even if I was on the phone the whole time (which not even close, just txting and using it when you're awkwardly alone while your friend goes to the bathroom)- WTF!?
I'm extremely vigilant about charging and monitoring battery life and despite my best efforts I get burned constantly. I even have this thing on airplane mode at work (in a basement) cause it will be dead by the end of my shift.
Any one use a rom that gives a noticeable increase in battery life? Doesn't seem like many of them are mature enough. Juice defender doesn't seem to help much... do I have any decent options? I may start carrying around a second battery but seriously, that's a bit silly.
/venting.
you have a bad battery, just call up Motorola and see if your still under warranty, if so, have them send you one, that's what i did and i've noticed a substantial increase in battery life
Hey man, did you calibrate your battery when flashing roms? Battery will die faster when dont calibrate. Currently which rom are you on. also check some programs that might run in the background. Right now, im getting about 17 hours, but i am over clocked and under volting this bad boy. I posted my battery life prior to running jokers ROM. Check it out.

I think I have some issues with my battery as well. It discharges fast! I usually have it full all the time but the times where I have left it discharge cause I'm lazy I wonder how everyone post pics with 13+ hrs when I feel like my won't get even 10. Btw, my battery has been in water for a brief moment idk if that affects it somehow?
Sent from my MB855 using XDA App
In my experience, bad battery life is usually related to some apps or settings wrecking havoc in the background. Unless you happen to have a phone with LTE and a smaller battery of course.
I always get an average of 30 to 40 hours on one charge with moderate use on my Photon, stock rooted...
For me, live wallpapers demolished my battery life. Also, I completely formatted sd internal before flashing joker skinny.
No rom here, just rooted- lime green theme. I didnt calibrate but for a theme i shouldn't need to? Ill look into getting a battery from moto, no reason i shouldn't be covered.... Aside from rooting that is. Also wouldnt phantom app drain show in the pics posted?

To all SGS2 owners,
Can you tell me how long this device last, generally use and talk time?
Some sites indicate it has 8 hrs talk time but others such AT&T itself, BestBuy, Costco do say it only has 3 hrs talk time.
So is it only 3 hrs?
on OEM battery: 10 hr and 30 minutes today and still at 74% medium usage
as for talk time i dont talk for hours and hours so i dont know lol but i can make all the calls i need and have plenty of juice.. i recommend using a cutom ROM like unnamed to save battery
on the extended 3500 battery: i got 41 hr and 30 minutes and i was at 19%
62% left after what I consider heavy use. E-mail, GPS, Wifi always on. It's a work phone so multiple calls during the day.
I'm using Unnamed ROM and even updated the ROM today to the latest version on battery. (hence the dip in the graph )

This device gets excellent battery life, especially after you root and freeze useless apps. Alternatively, just install UnNamed ROM.
Mine is bone stock with nothing more then Juice Defender. Tons of app's Medium use my best is 2 days 1 hours and change. Heavy use, Streaming 4-5 hours, lots of talk time and text with surfing with mail was my worst at 10 hours 48 min.
I am VERY happy with the battery life!
my phone is usually dead within 8-10 hours.. light usages in my view..
Alls i can say is that i went from 100-0 in 6-8 hours stock rom to 24-30 hours + with unamed rom... cant thank gtg enough

That is because you phone is awake 80% of the time according to your screenshot. If you want to improve battery life, look for the app that is causing it to stay awake.

You get only 8 hours because your phone never goes into deep sleep.. It is awake most of the time.. You may want to look into that..

Battery life is so dependent on your usage that almost all comparisons are worthless. I have learned its best to just make sure everything is running as efficiently as possible.
Surprising how some are getting a days worth on the battery.. I'm lucky to get 14 hours..
I can go 8 hours tool its dead or 14 with life to spare. It usually depends on how bored I am at work.
That's why I said its almost too subjective to compare.

Thanks so much, ladies and gentlemen. Very appreciate.
It does make me feel more confident getting this phone.
Is anyone else finding it extremely difficult to get through the day without struggling to keep your SIII alive? I thought the battery life was supposed to be superior to its predecessors? I'm a first time Android user but I did not think I would have to lower my brightness all the way and constantly monitor my devices battery life.
do you have some dumbass apps draining your battery?
i found my culprit and it's Friendcaster without even turn the notification on
get Badass battery monitor to find it or just use the one in setting
I'm finding the battery life is great, and lasts a whole day with no problems
It really depends on what do on your phone.
Try posting a screenshot of your battery stats. Android has an inbuilt monitor with each app and its usage being displayed. Easy method to spot a drain.
I just downloaded that in addition to my other app but there doesn't seem to be anything out of the ordinary that seems to be killing my battery. Most of it is coming from my screen but I keep at it 25% brightness the whole time. Super odd
I usually get around 16 hours of standby and at least 4 hours or more of screen time.
You should try Watchdog Task Manager. It will be able to tell you if an app is running and using more processes than it should. Also I've never used badass battery stats, but better battery stats will tell you if anything is holding a wakelock. It is free for XDA members so you don't have to buy it on the market. Just search for it

On saturday I drove for 4 hours streaming music via bluetooth to my car. Used navigation for about 40 minutes with the screen on the whole time. Took a few calls, sent a few sms's. Read a few forums using data. Got home that night with about 40% left. That'll do me.
Maybe I'm just freaking out about the whole battery situation? I just expected it to be a lot longer and a lot better. I constantly worry if I'll be able to make past 10PM when I start my day at 7AM.
On wifi with little to no voice signal that cuts out frequently, I might get seven hours of screen on time today D:

I'm getting huge drain from Cell Standby.
It'll lose 30% overnight. I keep checking for a software update. It's got to be the modem.
I'm holding off on rooting and custom ROMS until I know for sure this is fixable in firmware.
My phone's on LE6 and is from Thailand.
I see that you have poor signal reception
maybe that's why
last time I went underground, just 5 mins of standby it took away 10% of my battery
when it searches for signal it drains a lot
you could also try to disable auto search for network
go to setting>more settings > network operators and select it manually

Hi, the battery holds up quite nicely even with the little 2020 battery. I can easily get at least 9-12 hours of moderate but mostly heavy use from the phone. The battery LIFE compares mostly to the S3 with this battery LIFE being slightly better from my tests.
Sent from HTC DNA "The beast of all beastly phones"
Moderate to heavy user: Get about 13-14 hours on a full charge with about 3-4 hours on screen time. Almost identical battery life to my S3 using stock Rom's as a basis for comparison.
This is what I see on a light day. Heavy usage is about 12-14 hours.

+1 for gsam, great app.
What does it matter what his current screen time is? Two people just told you they get 5 hours of constant screen time and 3 hours would be a bare min with hard hard gaming and tasks. For what this phone is, it does fantastic for its battery.
And if you are spending 5 hours staring at your phone you may just be an inrovert. Lets think about this, if you spend 5 hours glued to your phone, thats 20% of your day blocking off everything around you. Thats alot of things to miss out on.
Is that 5 hour mark achievable with just LTE and no WiFi?
I get a full day (17ish hours I am awake) with at least 3hrs screen on and will goto bed with at least 20% charge left.
edit: I also have 4g and wifi on throughout the day - never turning either of them off.
The battery life has a lot to do with your signal coverage.
Take this as an example. For the first few months with the phone I worked in an office with poor signal reception. I mean bad. It would be hunting for even a 1X connection on minute, then showing full bars of 4G the next, just to lose it all 10 minutes later. (It was the building, not the phone). Now I'm in a new office that has excellent 3G coverage (4G seems to come and go, I blame Verizon).
My routine is the same. Unplug at 6:30am, moderate use throughout the day. At the old office I'd be down to 30% or so by lunch (12) and if I didn't charge it I'd die around 5:30pm. At the new office I actually forget to charge it during the day sometimes. It'll last until 8pm. And that's using the phone a good amount during the day.

What ROM/kernel/settings are you using? I've never gotten over 4.5 hours.
I don't know about screen time but I'm right over 12 hours off the charger today and have 53% left. Most days I have between 25% and 35% left when I put it on the charger at night after 16 hours. No wifi, LTE on and auto brightness. Only had to charge it twice before the end of the day.
I will install GSam though. I'm interested to see what my actual screen time is.

That's a little higher than normal for me, for example, today I'm at 15 hours and have 14% left.
On days where I use my screen a lot I get less.
The other night I was working on some late night research and my phone was plugged in and I noticed the charging light turn green. Knowing I had at least 5 more hours to go before I was done, I un plugged it, put on Netflix over 4G, streaming some hd movie my kids watch, since Dr Seuss about trees. Anyway, i let it play at full brightness and recorded the time and percent. It died at right around 5.5 hours.
I ended up using the best fit line (linear approx) and wrote a model of battery life as a function of screen tine, brightness, and 4g vs wifi. I'll see if I am find it.
But over 5 hours is pretty respectable though. I was impressed.
