i have installed villian 3.1 and since then my battery has only lasted a 1/4 of what it should do and i was wondering if there is any software or any tweaking codes i could use that will help extend my battery life????
Hi,
I'd follow this guide and install the overclocker widget. It bascially slows your cpu right down whilst your phone is on sleep. Made a BuGE difference to my phone.
Guide - hxxp://forum.xda-developers.com/showthread.php?t=628178
The reason for the battery life is a bug in DMAgent. There's a fix available that's designed for VillainROM 3.2, so if you upgrade to that and then appy the fix listed in this wiki page: http://wiki.xda-developers.com/index.php?pagename=VillainRom3.2Fixes that'll solve your problem

try Defiance rom as it has battery fix included. few of us are testing to see how long battery does last and if its actually this dmagent thing causing the drain issues. so far so good after 7 hrs
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.
I'm using Seraphim and I'm happy with the battery life. It seems to be worse than the GB ROM but I can get about 2% down every hour when the phone is idle.
I am thinking of trying different ROMs and battery life is very important to me. Which ROM will give the phone a better battery life based on your experience?
Thanks.

i should include ICS in the title. I am looking for ICS ROMs.

ah ok, im in search of a good ics battery friendly rom as well, actually downloading dag's ics "hybrid" rt now. i'll give it a go for the next couple days and post back. i was seeing about the same as you for seraphim.
In my experience, unless there's a bug, a ROM has little effect on battery life. Android is going to use a certain amount of power to run itself, and there is little that a dev can cook into a ROM to change this. Beyond the system, battery usage is from the screen, apps, and radios. If you are in an area with poor reception, and have lots of apps and widgets that frequently update in the background, this will decrease battery life.
I've used both DaGr8's Alpha II and Seraphim, and my battery drains less than 1% per hour when idling.
Guys a Search would have told you that Battery life is 99% on the user and has almost nothing to do with the rom. We could be running the exact same rom and get very different battery lifes due to the apps we use and how we have the device set up.
In the end there is not best rom. Only what works best for you.

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...

Hello guys, i had some serious battery drain issues. I tried installing different roms with different Android versions but problem persists thru all of them. I seemed to have had best results with unofficial roms like OzcanRom. Now i got LineAge OS installed because android 5 is too outdated by today standards i miss allot apps. I will include BBS log as ive got no idea what to look for over :crying: there and i hope some of you guys can help me
I posted BBS log in paste bin as i didnt know how to make it work here. Here is the link: pastebin.com/AXJ9sz2g
Due to spam protection it didn't alow me to paste normal link but this will do just as good of a job
Im getting about 9hrs of stand by time with 1 hour of SOT.
Update
So after experiencing few more bugs with LineageOS i decided to revert back to OzcanRom and tweak it myself. I applied some tweaks with custom kelner, eliminated all wakelocks and background drains. Now i have around 13hrs on battery and 3hrs of SOT and now i dont have to carry 10000MAH external battery with me. If someone wants me to write in detail what ive done post reply or PM me

I would love to know that, just got a Galaxy Alpha at I plan to apply custom kernel and ROM, so which tweaks to use would be very helpful
Hi. Could you please tell me what to do to stop battery drain?
