I recently got the galaxy s2 and it is my first Android phone. I love it but the battery life wasn't great. I recently rooted my phone and flashed with unNamed ROM and I feel like the battery life has doubled. Has everyone gotten this or could it be something else?

Battery life is great for me. The general census seems to be the same bro. UnNamed is an awesome rom that uses entrophys kernel that should increase the battery life of your device. Welcome to android. By the way. Cognition is an awesome rom too along with serendipity.
I flashed to UnNamed rom yesterday, today is my first full day with it. With moderate usage after 10 hours (wifi mostly off for the day), I'm sitting at 80%, with stock, I could barely make it to 15 hours.
What I noticed with UnNamed rom is my AOS usage is stable under 10% through out the day, where it was almost always >65% with stock!
Thanks for the reply guys!! Yeah it amazing how much better the battery has gotten with this ROM. I almost started to think the battery meter was off but I ran it down and its not off at all. Im not exaggerating when I say its getting double the time on a charge.
It seems to vary a bit for me. Yesterday I was at 75% remaining after 12hrs and I was using the phone a fair amount as I was off work. Today, also off work, I was down to around 45% after the same time. I didn't do anything more out of the ordinary but then again, I didn't specifically monitor it that close both days.
Either way, it's till much better than it was with stock.
Yup, there's crap in the stock ROM that drives data usage, which drives AOS up and kills battery.
Although: My "experimental" series kernels are based on 2.6.35.14, which it turns out hides AOS reporting without reducing drain.
OR - AOS was reported falsely high to begin with.
Still investigating.
FWIW, I have both Wifi sharing apps frozen in TiBu, but then I had it froze before flashing UnNamed, didn't see much of a battery increase until I flashed new rom.
As for AOS, it would start around 25% then fast climb to >90% in stock rom, I spent hours experimenting with different combos to see if anything definitive triggers the "reported" AOS drain, but nothing helped.
Anyways, I'm very happy with UnNamed and intend to keep it for now as I see no reason to flash to others at this point. A big THANK YOU to both gtg and entropy!
are you guys that are seeing reduced AOS use in UnNamed using Wi-Fi at all?
There seems to have been some correlation between turning Wi-Fi on in the stock ROM and increased AOS usage.
So I'm curious if this correlation disappears in UnNamed?
What is "AOS"?

My guess is there's some app in the stock ROM that gtg removed in Unnamed that is set to only use data when on wifi.
My high AOS problem in stock was not directly related to wifi being on. Once it reached >25%, it just kept creeping up sans a complete reboot.
Ah ok.
But your problem has disappeared since you installed UnNamed?
Yup, it's now anywhere from 2-15% during the day.

I have been using UnNamed for about a week, added task650s theme...
My battery life is noticeably improved over stock. My AOS is at 13%, third down... I never noticed what it was stock, just know this is a great ROM. Fast, stable, great battery life.
I forgot to ask gtg - is he including experimental or non-experimental?
If the kernel version is 2.6.35.7 - if AOS is less than 10% for you, you are doing EXTREMELY well.
If 2.6.35.14 (experimental) - That alone will make AOS display as far lower without actually changing drain statistics.
How does a different ROM improve battery life so much over stock? I already rooted and removed most of the bloatware, but I'm still concerned about battery life. I wonder if it's worth switching.
EDIT: Some posts are saying that it's the kernel. If I just go ahead and install it from: http://forum.xda-developers.com/showthread.php?t=1289460 while still staying on the stock ROM, would it help my battery life?
My kernel is 2.6.35.7
Yesterday, while on the go, AOS stayed between 8-12% range. Today on charge, it's stable at 2%.
My kernel will provide some improvements in battery life, although I wouldn't consider there to be anything drastic yet compared to stock.
Unless you fall victim to the fuel_alerted wakelock... That one's nasty.
I might had been the victim of that wakelock, seeing how event/0 and suspense were killing the battery on stock rom.
Hello there folks!
Sorry if this question's been asked before, but it seems that with the recent (quite amazing!) accomplishment of CM7 on the X2, the information on compatibility with certain scripts/apps/etc. is a little scattered.
That being said, I was hoping if anyone knew if the Speedy scripts would work on this ROM.
Thanks for the info!
Why do you even need it? Its amazing without it already

I installed it a couple days ago and things seem to be just fine. I didn't install it for performance gains though. When I was on liberty I had it installed and it made a huge difference with battery life. That's something that (although it's not terrible) I haven't been real happy with on cm7. At least. Not compared to what I had on liberty. So, I figured it can't hurt to try it (can always restore a nandroid) . So far, it seems to have made quite a difference for me when it comes to battery life. Don't know if it messes up something else or not. If so, I haven't noticed it.
My battery life is different every day with CM7... with ~same usage. Some days the battery will take FOREVER to drain and others it goes by too fast. Turn Data off while idling
Okay. So I am currently running shostock3 on my sgs2 with siyah kernal. I read the article from zedomax on galaxys2root.com that it has very good battery life and very stable but when i am running it, I have terrible battery life and i am currently underclocked or whatever the word is. Is there anyway to fix this?
My advice, run SHOstock3 as it was released. It runs great as shoman94 dev'd it.
...and stay away from that web site u mentioned.
Stick to XDA. Period!

Yes. I'm running shostock3 with the included kernel and get good battery life.

Getting great battery life on Shostock3 V3.0. Flashed the AJK 1.52s kernel. Checkout Better battery stats...see if you have wakelocks killing your battery. And..I agree that website is no good..stick to XDA.

Most people get really good battery life on SHOstock3. Just search the SHOstock3 thread for the word battery to see what I mean. If you're not getting good battery life, you need to find out what in your configuration is causing the problem, and fix it. There is a thread in the general section started by Entropy512 that you should study to help you identify where the problem is.
I was on GB ShoStock for a long time thinking ICS and JB would never leave me satisfied on battery life.
http://forum.xda-developers.com/showthread.php?t=1353513
Finally came to my senses and tried out ShoStock 3 and have never looked back. To make it short the best Rom Ive ever flashed for any device I have had in the present and past.
You definitely have a rogue app killing your battery, find out which one it is and uninstall.

Sorry you have battery life problems.
I have been running Shostock3 since it came out (it's version 3.02 today!), but I also been on and off at least five (wow can it be that many?) JB roms on my SGH-i777 (won't even mention the # GB roms here!). After trying many, I must agree with the other posters who state that this rom delivers very good battery life when compared to stock and when compared with other custom roms.
Lately, it has delivered the best battery life I have ever had on this phone using any rom (although SlimBean JB provided very very good battery life for me recently as well! Also UnNamed was great for battery life in the old GB days )
I followed the recommendations made by creepyncrawly to read Entropy's (& others) battery notes/faqs. They provide some really good background, some with that typical "XDA flavor" (read technical!. That material, plus some more plain old simple user adjustments to how and what I use on the phone have improved my phone's battery time; and it might help you as well.
It really boils down to the fact that each phone user loads different apps and our usage patterns vary.
Assume that you've flashed it and let it settle for a few days and several recharge cycles. After doing this you can see what YOUR "norms" are. They may be good or bad, but that's the baseline for you with this rom and with the apps and usage pattern you have.
(You can tweak voltage and speed (well, not speed on SS3!), but my experience has been that the more noticeable changes will be by adjusting your pattern of use, or doing the "hunt for the app" (or apps) that are burning down your run times when not in use.
Not many here seem to like or do this, but I would also try one of those "help-you-with-battery-use" apps --like juice defender (Ok, I get that many here seem to think it a waste, but it really did help me --a little-- when I used it); or get DS Battery saver (a bit more aggressive and noticeable, but you also notice the lag while you wait for things to turn on when you want them).
Actually, these may not be precision solutions, and don't focus on your specific phone app use, but they do work in a macro way to slow battery use and simply working with them for a few days or weeks will provide you with a better a sense of what the heck is going on under the plastic; they will cause you to look at what you have/run and when.
Oh, this includes using Better Battery Stats, which is fine for reporting out exactly which the apps behave --or don't-- and by how much and when. I'm not slow (well, that slow but it frankly, it took me quite a while to figure out what I was reading in the BBS readouts and what they meant! (Now, after a year+ or so of using it, I don't even have it loaded, since I've done the fiddling I need --and BBS, plus those other battery apps, helped me to figure out what apps worked well, what apps I was willing to sacrifice battery on and what apps were useless and should be tossed.)
Finally, some roms just don't work for people! So it's not worth the frustration chasing something you may not be able to achieve with this or another rom. (You probably read how individuals have problems that you don't -yet, you run the same rom and the same phone! That is our world. So, too, you will read about some who make amazing claims on how long they continue on one charge. Some are pretty amazing, and some may even be real
My final five cents would be:
#1 run the rom a couple of days, get a baseline. Then switch from Jeboo kernel to AJK's latest for TW (I think it is 1.25ss, but I really also had great results from 1.48s) and run it a few more days. They were pretty much even for me, but others find one or the other kernel makes a real difference!). Compare after doing the same activities through a charge or two.
#2 If your battery life remains "poor," note what poor really is (ex. how much screen time? and how much total run time prior to getting to zero or 10-15%? ...something like that).
#3. Then get BBS and one of the "automatic" battery-saver programs and work with it for about 4-5 days and that many recharge cycles. See what your norms are but do it for the same type of usage!!! If better while using the battery fixers, then you can work at picking off the app or apps that are sucking your battery more than you want. Not as tedious as it sounds. Of course, staying with a rom for three weeks might be a challenge :laugh:, but this is a nice rom to work with.
#4. I don't think you will need to under-volt to get good BL. I wonder if your phone is stable in doing that? Or, does it induce additional lag? That might be a high price to pay for more run time. (You could compare the UV results with your "norm" as well!)
#5. Finally, we are on Galaxy S2 Sgh-i777 -and can change batteries all day long for not so much per battery! It is not elegant, but it works. (Done it myself several times -even with good battery life).
Good Luck!
Best ROM, Good battery life... been with Shoman's ROM since shostock2 never have a problem with the battery life...

Well I love the jb roms....ive tried pretty much every one of them for days at a time. But I cant walk around charging my phone all day. Ive read all these stats of people getting days with a certain jb rom on their fascinate...which sounds great, but that just isnt the case here.
So, when using an ICS, the battery life seems to be much, much better. Particularly with Gummy, although ive had other strange issues...but the damn thing atleast doesnt keep dying on me.
Does anyone have any recommendations on a stable ICS rom for the fassy? Im looking for good battery life...not so much tweaks. Or would I be better off to go back to GB? I tried CM 7.2 but wasnt really impressed with the battery life on that even compared to Gummy. Thanks for any help guys.
Also, does anyone have a copy of the Devious ICS rom?
Best ROM's for doing anything would fall on the individual - with so many variables involved, user apps/user tweaks/user usage the only real way to find the best is for you to flash and run and test....
Thanks
I know sounds crazy but Ive never been happy with the battery life in my Rezound...but now it seems that with every new android iteration that comes out it gets a little bit worse. I remember when I was unhappy with getting 2+ hours of screen on time and now Im wishing I could do that again. I definitely got better battery life on ICS...not really sure about gingerbread because Im not sure Ive ever ran it on this phone.
Anyone have an ideas on where I can find some? I know its a bit of an odd question but as of now Im looking for the best battery life I can possible get on 4g over anything else.

Try EclipticRez Revamped v9... It gave me the best battery life of any ROM on the Rezound. The main drawback is Google Now, it is not supported in ICS and there is a hacked version in the ROM, so you can't update or change it. If you don't use this your good, I just used Chrome and it's search function.
I never use google now anyway....
Well that was way too sensey, even de sensed, and it ran oddly on my phone...I just reloaded CM9..we will see how that does.
