On juggernaut ROM and I don't know why but my battery drains faster than my vibrant with ics I have no widgets or installed any apps

post some screens of battery use.
mines pretty good. apart from the basics try disabling wifi/4g when your not actually using the internet.
Hercules was here

I tried JuiceDefender on the market (Free one) and I seem to be getting better bettery life.

Stock kernel on juggernaut overclocks. this offers better performance, but drains the battery faster.
How long have you been using the juggernaut Rom?

WHOA it's rare to see someone say that the battery life is horrible in this forum. You should try a new fresh wipe and install, and try different kernels.

Try darksides super wipe then re install juggernaut ROM. Make sure not to run setcpu or any other cpu apps, I was having bad battery drain running setcpu.

Setcpu leaves a core on so I advise against it

i actually think those "battery saving" and task killer apps uses up more juice than saving ... i had juicedefender ultimate and i noticed my battery drain when it was enabled .. i deleted the app and ive noticed a great improvement on my battery .

Agree
I was also getting horrible battery life on the Juggernaut roms. I tried the bullet kernel, synergy, and faux kernels with all sorts of different ways to reduce battery consumption such as underclocking, undervolting, uninstalling bloat, and removing apps from startup. No matter what, my phone would always be dead by the time I came home from work/school (I'm usually away from home from 630am until 800pm).
I recently started using the DARKSIDE rom/kernel in the hopes that it would provide some better battery life and I am actually getting significantly longer usage times. As of right now after ~15 hours of time spent off the charger and with moderate use (~500 texts/day, XDA app, FB checking, random Internet usage), I have just under 40% battery life remaining. I must say I am very impressed with this rom and give the developer TDJ mad props.

So here's my battery life with Eugene's Macnut ROM:
Compared to this (Juggernaut 4.1 with ICS Ultimate Theme):

I run juggs with TDJ Darkside kernel, kernel makes huge diff

I am running Juggs 4.1 as well previously with the FAUX123 kernel and decided to try out TDJ's Darkside kernel. Wow, huge difference, highly recommend. I use system tuner app to adjust my speeds but main thing in system tuner app is to go into boot settings and set screen-off to powersave governor and max frequence to 800, 500 etc.
I also run easy bettery saver and that helps as well. Battery life is best I have ever had with my G2 and I got it first day it came out and have run most all of the rom's kernels on it. If you can I would suggest running TDJ's Darkside rom as well. I would but just don't want to reload again at this point.
DK

I'll try darkside rom and see if it fixes my battery drain problem.

Thank you for this, I wasnt aware of that, what do you use to change your clockspeed when your screen is off? I recently switch from an iphone and unfortunately battery life seems to be something I have to actually think about now. I know its a faster processor and a bigger screen so I get it, I just never had to worry about turning off wifi and things like that before. I currently am running beastmod 4.2 with darkside kernel. I have 9hrs on battery at 41% with 2 hrs and 15 min of display. Im not really interested in speed at this point so I thought setcpu was a good thing to use to underclock and use less battery. Can you recommend any good alternatives or should I not bother with setcpu type apps. Thanks in advance

On darkside... Not the current one but the one before it... I think it was version 1r2 or something like that. Battery is great, better than juggernaut. I have bluetooth and Wifi on all day

They gobble up a TINY bit more CPU (probably no more than 1% throughout the entire charge) at the cost of managing your data settings. It saves juice primarily when your phone is idling. It pings, it checks data thresholds. The main idea is that it turns off 4g/wifi when you're not using it, and back on when you are. This requires a little but of CPU, but you end up having a battery that lasts much longer.
There's never be a time when you're using your phone 100% of the time on battery. There's ALWAYS idle time.

[Q] Rom with best battery life?

Title about says it. If possible, with Touchwiz. I don't know why, I just like it (believe it or not). Thanks

Try Tuesday Blu ray by m & s. I get great battery life and performance with that rom

When it comes to pure battery life, I haven't found anything better then tdj digital warfare undervolted. it's about a stock as you can get in the looks dept. But the speed and battery life is just incredible. You can get 20+ hours with over 5h screen on easily.

The only ROM I have tried so far was Digital Warfare and it was very smooth and had very good battery life. I reflashed my nandroid backup though because having the T989D Telus model of the phone I get the 3G icon instead of 4G. The ROM also came with a bunch of T-Mobile apps that I don't use. I can uninstall them, other than that the ROM was great.
I hear good things about battery life while running Juggernaut or Telus Stock Rooted Lightly Tweaked. If either ROM is run with Faux Kernel and one of Gideon's UC/UV scripts it's supposed to have fantastic battery life. Still have to give it a try though.

The best battery life I've seen is my current set-up. Juggernaut 5.0 with Darkside v1 kernel. I think in most part because I can underclock Darkside to 972MHz during normal use and 1296MHz for heavy stuff without any noticeable performance issues. Truth is I could go lower for normal use but 972 seems to work for me.
If you guys are interested I could throw up a screen shot after a full pull if you want.
I'm pushing 18 hours of normal use (social apps, browsing, heavy texting and some youtube and pandora) with 30% battery left. Of course this varies but to get 22-24 hours of normal use and still not be dead is normal for me.
I've run AnTuTU but don't know enough about how these systems operate to say anything other than my score goes up when the cpu MHz goes up (shocking!!) but I can throw shots of the tests up too.
This combo is a stable as any rom or kernel combo I've run b.t.w. Much respect to TDJ and Whitehawkx for the products they turn out.

Battery life on Slim Bean 3.1.0

I'm still too laconic on XDA forums to post this in response to gmillz' SlimBean 3.1.0 ROM posting in Android Development, so here it is.
I'm getting the attached battery life after one day, one full power cycle on my new 1850mAh battery and fresh installation of the above referenced ROM. I'm running noop I/O and ondemand governor with the stock kernel built into SlimBean. I'm also running the screen on minimum brightness (not automatic). What else provides some useful background?

Here's my battery today on slim bean...I love this ROM

Since my phone "lost" my IMEi (actually, it was just not able to read it anymore), I flashed back to Stock Samsung 4.0.4. Before, I used SB 3.0.
And I can also report that battery life is much better now. Perfect example is a night in flight mode, which results in about 1% loss vs 6% loss @ SB.
As there are several guys I talked to which have perfect battery life with this ROM and I also had till 2.8 or so, there must be some misconfiguration. Or a battery draining app.

Where did you get the download for 3.1.0? I've checked there site and they only have 3.0 for the T989.

I've been running this ROM for the good half part of this day, and I must say, the battery is not as good as I hoped. Maybe I'll have to let it settle in, but CM so far beats this in terms of battery life.

I agree with the comment about stock being better than SB 3.0 and onlychevy's 3.1. It is a downer to realize most custom roms don't actually optimize for better battery life. I test the battery life by playing 5 minutes of youtube on 3g only to see how much is drained. On SB, 1% is drained for every 2 minutes of playback, and 3 minutes on stock.

(Q) .Best custom ROM with Touch Wiz on JB without themed stuff?

The title say all !
I really love the stock look of my GS3 (t-999V) but I need a ROM with good battery life and couple of improvements tweaks. No themes at all ! Looking for smooth and stable daily use !

That's how it should be but in reality it's not. Sammy roms have much better battery life but then again that could just be because there are better power and memory management features on stock. It's the only reason I've been reverting back to stock since almost every other cm10.1 based roms have ridiculously weak battery life.

that's kinda weird because on mine the battery on stock sucks but on cm10.1 it lasts a lot more so i was thinking the same for note2

Not really. Battery life is awesome at is on stock. You could flash some kernel like Perseus and do some undervolting or even underclocking to
squeeze more battery out of it though.
Battery life, I've found it to be more or less the same, if not marginally better on stock.
@bushako - How's battery life on MIUI mate? Heard it drains battery more than other stock based ROMs?

I actually ended up going back to stock based Rom. The battery life wasn't as bad as I had thought, it got me about 6hours screen time. Don't get me wrong MIUI really looks gorgeous but at the expense of performance, especially at this stage since there's quite a few bugs that needs ironing out and also because MIUI and xposed framework use the same setup they are incompatible and I'm use to lower DPI. I might get back with signs of improvements.
Also, I found that Perseus kernel is not compatible with aosp and that so far the one that does work is neak and redpill.
