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"?

Android OS -- a process that will show up in the battery status menu.

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.
Hey guys, I installed for a few days the Photon CM9 build and I absolutely loved it. The only problem I had was that it seemed to consume battery way too fast (and I calibrated it several times to make sure it was done properly)
It would drain around ~20-25% overnight. I don't know if anyone else is facing similar issues? And if you are, what steps did you take to remedy it? (As much as I appreciate nottach's work on TDS, I cannot go back to Gingerbread anymore )
I was wondering if anyone has any idea why my phone is getting really hot and the battery is draining too quickly. I just installed teamhacksungs ics build 7 from rootzwiki and before that I was running build 5 and it was still getting hot. I checked the running apps and there are only a few running and I have all the settings geared towards power saving. Any help will be appreciated. Thanks.
Hello
I am experiencing high battery usage on my Galaxy s2, and notably since I went on CM9 a few days ago. In Idle mode, it does not seem particularly terrible (I lose c. 1%/hour, while having 3g on all the time and 4 acc. on sync/exchange). I am particularly losing under usage. During the day I lost 10% by only listening musing for less than 1 hour. Android OS is high (as much as screen). Let me know if I can conduct any particular test to understand the issue.
I have not flash Kernel, I heard flashing Siyah might help ? Is it compatible with CM 9, and which precaution should I take doing this (have never flashed Kernel before).
Thanks for your help
If anyone has an idea I need it deeply as my battery issues are worsening... I'm enclosing a snapshot of the battery page
1% per hour, 3g and sync on? Count yourself lucky man that's good!

I've been stock rooted for several weeks now & have noticed that the phone isn't quite as fast as it was stock. It's not as responsive at times & even worse I've noticed the battery life has decreased. Before I rooted I could easily get a solid 12 hours & now I get 8 to 10. Last night I went to sleep & my phone was at 72% & when I woke up today it was at 12 which is horrible standby time.
This is the 3rd HTC I've rooted & I've never had an issue like this before. I haven't had a chance to go S-Off yet. Any idea on what it could be? Any suggestions on what I could do to improve the performance back to what it was?
Any help or suggestions would be much appreciated.

I'm not sure from what you have said what the cause is. I just know that I have used all of the different roms for this phone (I'm on Verizon) and never had any battery drain like that. Maybe a factory reset and watch what 3rd party apps you re-install? One (or more) may be causing the drain.
