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.
I love S2 for every feature in it
But thats my 3rd mobile which is causing Android Os High Battery Usage problem and there is still no cause i find yet
tomorrow i bought a used s2 of o2 carrier which was unlocked for my country everything was fine i check that in market android os and system was on 2 %
but i just did factory reset for deleting data which was of old owner
and BOOOM here comes the android os high usage problem again
now i am trying everything like factory reset,firmware changing but still no chance and its draining battery its my 3rd mobile which cause my same problem and 3 of them was s2
i also try to find one click gremlin remover for s2 but its not available because that thing was my last hope please tell me what to do
Hi ...

The android os high battery usage could not be a problem though.. I think that if you keep your screen on for sometime, the screen on time will go to the first place.. and I suggest you to try ParanoidAndroid Jelly Bean

first of all it should be spelled "serious"
and now if you are coming from a different OS like symbian or ios then here is the hard truth all android phones pretty much have comparatively(to symbian) low battery....
and give it some time,a few battery cycles will improve battery life...
ps:i am on stock 4.0.3 rom my s2 only lasts 1.5 days max only if i don't play games.....

so you are facing problems only after factory reset??
did you install any particular app, maybe that is causing the drain...
i would suggest to do a factory reset once more and check without installing any app the battery life
TouchWiz gives high battery drain compared to custom ROM's, probably due to the bloatware.
I will never use TouchWiz on an android/galaxy phone, I will always use custom ROMS

Really? That is so much good news to hear, Can any one tell me what should i do after flashing new firmware in my s2 , Some peoples saying dont delete battery stats files its cause some fuel alert wakelocks and some are saying only deleting battery stats files can give you correct reading actually i was thinking that the cause of android Os high battery usage will be the incorrect reading of battery what you say ?

Incorrect.
ONE complete battery cycle will re calibrate the fuel gauge chip. Once when i cycled my battery it stuck on 1% for over 4 hours. It does NOT give you longer battery life, rather it re calibrates the battery indicator.
OP if you want better battery life try this:
Use a custom rom, or a frankenrom if you like the stock feel, or a rom modded for better battery life
Look into what services are running and remove the ones that are running when not expected
remove the facebook app,
use less widgets (since they use more battery),
choose a darker background (AMOLED screens use the most power for white),
turn down the brightness,
have GPS, WiFi, and Bluetooth off when not needed,
turn off auto updates,
anything that automatically checks for stuff, turn that off or increase the delay,
Use a kernel that supports under-volting and under-clocking. You have a powerful phone which rarely needs to use all the power. Under-volting and under-clocking can help you get even several hours longer out of your device without a noticeable impact
Turn off those damn task killers. Its more efficient to not have a task running than to close it every 5 minutes and have it auto start up again. task killers were great for android 1.3, not so great for 4.0
In my class there is one other guy with an S2 and every day i hear his battery beep at him that its dying. I can go about 2 days of similar usage with no battery problems. Why? Because i spent time and effort to learn why my battery was draining and how to make my device run as smooth as i can.
TLR Do some research. If you want everything given to you buy an iPhone.

Brother i am suffering from a very sereus problem i dont know my android system and android os battery usage goes to high i celibrate my battery many times but its not working for me
zain, dont fret yourself over the battery backup duration. With frequent usage, you will have to charge twice a day at the most. Your battery will still last 2 years.

Hello,
I'm running 2.3.6 now and I wonder if I switch to 2.3.4 will I have less battery drain? Are there any functional lacks on 2.3.4 comparing to 2.3.6? However, I use GO Launcher on rooted phone.

Well next time please do post questiona in the general sub forum Anyway I think it is better to just update to 4.1.2 since you are rooted anyway. I get better battery life and signal on 4.1.2 compared to 2.3. My choice of a rooted stocked based rom would be NeatROM Lite by Sale :good:
I agree. Generally, upgrading rather than downgrading will increase performance so I would just go wit a higher version. Also, if you feel you have an unnatural battery drain, there are other options except switching versions to handle that. Maybe it is one of your apps that causes the battery drain. Other possibilites are sync cycles or kernel. If you switch to another kernel that might help your problems better than switching ROMs (although switching ROMs is always recommended, just for the fun of it )
gulypi which
I don't know if I am doing something wrong, but I just flashed NeatRom 5.0 and the battery life is terrible.
From my point of view, 2.3.4 stock with speedmod kernel was the best with my s2. I had battery life for 2 days. With latest roms I have battery life for max. 24h. I always did a clean install with factory reset. Don´t know why the battery life is so bad with my phone.
But now I ll give it another try. I will format the whole phone and try sentinel rom again which i liked most
NeatRom 5.0 killed my battery also. Trying 4.9 for now as I jumped from 4.6. If it's buggy I will switch back to 4.6

Media scanner fix for battery problem on neat ROM should fix this. Also Apollo kernel is great mix with any stick Sammy ROM.
I don't know why flash modded kernels (at least if you are about to have better battery life, not other mods)? I have plain stock GB 2.3.6 XWKL1 (DDKL1) and just use Go Power Master, Set Cpu and calibrated battery.
At first when I went back from ICS to GB battery lasted for 14hrs. I charged battery fully on and battery "learned" new system and went up to 23hrs. Then I calibrated battery: fully discharge till phone went off, again started, playing till off again and again till it won't on. Then without turning it on I charged battery fully, unplugged charger, waited till battery went to 99% and plug in charger again till 100%, and again. I was using WiFi over half time of usage, flight mode at nights, play wit phone settings, installing apps, browse internet a little, use as phone as usual, listen a music a little, browse photos, etc, and battery lasted for 39hrs on stock battery which previous owner using for last two years and he didn't care about healthy battery usage. I got Samsung Extension Pack with 2000mAh Battery and flat back panel but it waits for new S2 I bought yesterday. I will put new battery after ROM flash and get all restored to state I have now, then I calibrate that bigger battery for new phone.
But anyway, question was if someone was playing with 2.3.4 and 2.3.6 stock ROM's in order to achieve better battery performance? I read somewhere that guy had over 4 days on stock battery and 2.3.4 GB. So I wonder if I switch to 2.3.4, which may be probably less demanding system than 2.3.6, will I get more time on one charging? I don't care about how it may or not look like cause I use GO Launcher anyways, but does it have same stuff and functionality as 2.3.6?
The problem with comparing your phones battery life is that it's depending on too many variables. You can't just say 'My phone lasted 30 hours with this and that usage', because everybody is using it differently. If you really want to test it, flash both versions yourself and try.

In addition to Donnie's very good point, you're asking about 2yr+ old firmware. Do you realise how few people on a site like this are actually running firmware that old ? You'd probably find a fair number of 'ordinary phone users' out there who are still running GB because they may not be technologically au fait enough to do an OTA update.
At the end of the day, changing firmware to squeeze every last drop of battery life becomes a game of diminishing returns in that you can spend a lot of time to get that last tenth of a % of use out of every charge. You have to ask yourself is it really worth it, or is it worth simply enjoying your phone & chucking it on charge every night (or if you really chew through battery, getting a spare).

Well, the thing is I don't understand why people update their phones and then complain about battery life if 2.3.6 works fine from what I observe here and there.?
As per Donnie's post, there's too many variables involved to say 'This Android version will definitely give you better battery life than that version'. Personally, I get better battery life out of JB roms than I ever did out of GB or ICS roms, not that I got poor battery life out of either of those though. And the reason for that is I worked at it.
There's no magic simple A-B-C to better battery life, regardless of what rom/kernel/Android version you're running, you have to experiment & try stuff out to find out what works with the way you use the phone/have it setup.
People who complain about battery life & attempt to pin it on the particular Android version they're running tend to have a really poor understanding of 'how it all works', because it isn't that simple as I've said.

People can also update their phones because of other reasons than battery life. ICS was the best for me with battery usage, but after JB downgrading isn't an option for me as I would miss to many new features and other additional functions.
The choice is yours to make. If you are satisfied now, I would stick to 2.3.6 if I where you. If you are curious about other versions -newer or older- try those
Hi everyone!
Some days ago I bought a new battery for my S3 (seller said to be genuine) and I am disappointed because its performance is almost the same as the one I was experiencing with my old battery (18 month-old battery). For this reason, I have been researching and I have done this until now:
*) Being honest, this comparison is somehow subjective since apart from the battery change, my S3 was officially updated from 4.1 to 4.3 almost at the same time I changed the battery. Then, I wonder whether this update may have affected my diagnosis on the battery duration.
1) According to the point * I decided to do a battery calibration "without root" consisting in draining the battery to 0% and charging until 100%. I haven't seen any improvement doing this.
2) As consequence I analyzed wakelocks. I have addressed two of them from the System:
- AudioOutLock. to fix this one I did as recommended: disabling sounds when typing and all of this.
- Backup. Fixed by disabling the backup from Google (I would like to have it enabled but if it is causing a battery drain...)
3) I let the phone the whole night turned on with the 3g connection on and I got a ratio of 2%/hour draining. I have read this is more or less under the normal parameters.
After doing all of this I'm still not happy with the performance. Usually, my mobile gets under 20% by the end of the day with the screen on in a range between 1h30m and 2h. If I remember well at the very begging (when I bought my phone), I was getting my phone at 20% by the end of the day but having the screen on for 4h or more. After buying a new battery, I was expecting to return to that situation.
Do you have any hint? As for example a better way to calibrate? Factory reset may help? Should I check a specific wakelock?
Thank you very much in advance!
I forgot to mention that when I let it charging over night, my s3 does not always charge until 100. Sometimes it's until 98 or 95. I don't know if this helps you guys as a hint but I want to provide as much information as possible.
Thanks

Thanks!, I will check. But so far I have briefly seen it looks like there is not a specific solution more than disabling gNow and some other things. Maybe a good option is to downgrade or using a custom rom in which there aren't these problem.
its same to me.

Thanks!. I have been using Wakelock detector but I will try with this one. I was wondering if using this kind of applications for checking the wakelocks may provoke some battery drain itself. I mean, should it be used just for analyzing when you experience a battery issue? or should they be permanently installed no matter whether you have battery problems or not?

Hi, Better Battery Stats is using an already existing process of Android to obtain it's information, therefore the influence of the app itself on battery drain should be negligable.

Thanks for the info!. I have not seen anything special in the partial wakelocks. In the kernel wakelocks, it is difficult to distinguish whether one entry is specially problematic or not. After what I have read so far it may be the mix of social apps I have now installed:
- Whatsapp
- Twitter
- Messenger (FB messenger)
- Line
I guess maybe I have too many of them reason why the battery is draining more than normally when the screen is off

sometimes changing kernel could solve the problem..boeffla is the one i am satisfied with..and agni kernel is also one of the better kernels..:good:

Sorry for the delay to answer, I've been busy. Here I post the images of the battery stats. Sorry, they are not what you told me to be having them 5 hours quiet (that's difficult for me). However I can tell you that the 40minutes of screen on where just chatting on whatsapp or checking emails; no angry birds or need for speeds hehe... Are these images ok to be posted on the thread you told me? Thanks in advance!
I had a poor battery perfomance after upgrading from 4.1.2 to 4.3 until I've disabled fast dormancy. It seems that in v4.3 is enabled, and if your carrier doesn't support it, it will eat your battery. Donwload free from market "fast dormancy togle" by Siyah, and that's it

I have just rooted the phone and disable the fd. I hope this works!. Thank you very much for the info. However, now that I have it rooted, do you suggest to install a custom rom for getting a better performance? if so, which? there is a good one with 4.4 and multi-view?.
Thanks in advance!
Try flashing allblacksback mod it makes the whole system dark and saves battery on display and also I recommend disabling Google play services but this means there will be no push services but it saves a lot of ? ? ? ?

After giving a try to the idea of disconnecting the fast dormancy here I give you some reports on the battery consumption. I don't know why but statistics are wrong from the point of view of the duration (3 days).. since I disconnected it just 10 hours ago. I think its consumption is still huge. I hope you can give me a hint on it. Thanks!
Ive installed smartdroid. Battery perfomance seems quite better now! What do you think from the screens? However.. i find the screen too much consuming.... ive seen people managing 5 hours of screen in a day. Why i am not? May it be battery or configuration?
Thanks!
Do you have any hint on this? Ive seen that with the screen off the consumption is really good. However, with the screen on a doing normal stuff: chroming, feedlying or whatsapping it goes to a 20-25%/h.
I installed cm11 on my s2 a while ago using the installer and since then im trying to figure out the reason for the huge battery drain. Cm works great but it drains the battery in an average rate of 19% per hour (a special app did the math,and i can clearly see for myself ). I dont do anything more than music, surfing and whatsapp. Android stats usually say the screen is the no1 battery drainer. Android os second.
I searched the internet and tried every possible tip there was. IMO the only thing I hadn't tried is flashing different modem and different kernel (didn't find good guides for it and was afraid to brick the device)
What I have tried:
1. Flashed neatrom just to compare. A little improvement but still not like old days and of its not a good performance like cm.
2. Went back to cm through recovery backup and Used battery stats, taking permissions away from every app with a redundant wake/cpu lock.
3. Got new battery, assuming the problem may have to do with an old battery (bought the device 2yrs ago)
4. Calibrated battery both with the app and also using the manual trick (chrage while phone off, take batter out, wait five mins and put back in).
5. Tried different governors.
Might be forgetting other things. Nothing works!
What can I do? I really wanna use cm and not get lost flashing less good roms.
Thanks
This device uses an old Exynos SoC optimized for Android 4.1, In new versions is normal battery performance loss because there is more consumption of resources
It also warms up and all.... You recommend flashing older version of cm?

Yes, only if you really need more battery life. I have a Galaxy S Advance, who died in the 4.1, Battery life in 4.4(CM) is 30% lower than the official 4.1.
