After doing a bunch of research, I think I'm going to flash ParanoidKANGdroid. It seems to be a really nice combo of features from many of the top development forks.
That said, I'm concerned that with the amount of features that are packed in there, the battery life may take a hit. Is this indeed the case? Or does it get a good battery life? If I'm concerned for battery life but still want to try out JB and possibly some of the other custom features of CM10 or AOKP or MIUI or ParanoidAndroid or etc., is there someplace else I should look?
I flashed SuperNexus and then underclocked it to min 192 max 1.1ghz gives crazy good battery life highly recommend it!

Hey guys,
I finally installed CM7 a few days a go (nightly #74), and I'm very pleased with it. The only downside, really, is the battery life. It's usable, but it drains at least 40% faster than Samsung-based ROMs.
Most of the power seems to be going to Cell Standby. I hear some of the custom kernels can improve things a lot.
Could those of you who have experimented with different kernels give me a good recommendation for a kernel and/or modem release which will work well? I just don't have time to spend hours digging through hundred-page forum posts these days...
Thanks in advance!
Glitch is good. Battery will be a bit better with a custom kernel but it still won't be as good as Froyo. Just the way it is.
What's your cell standby reading? Percentage of battery use? Also of android system and OS,?

i recommend NEO 9 v5 it has great battery life and its really smooth it comes with led version and no-led
When I ran CM7 Nightlies a while back I always stayed on the Stock Kernel. I guess that since Kernels aren't updated "Nightly" like the Nightlies you shouldn't use other ones. Just my personal preference.
Stock kernel is more stable but other kernels give better battery an there much smoother

This will likely be a controversial topic, but I'm going to risk it.
Also note that this is not meant to be a jab at kernel developers, or an attempt to lick CM developers' balls.
I have just been thinking. Custom kernels often claim an improvement in battery life or performance with their kernels. With Samsung ROMs, this is believable. The case of the fuel_alerted bug not being fixed with Samsung ROMs is an example that Samsung kernels aren't the best.
However, with Cyanogenmod ROMs you would think that the developers of CM would know best, since they *probably* work far more intimately with the code than custom kernel developers. Has anyone found an improvement in battery life with a custom kernel as compared to the stock CM kernel?
Now, I'm aware that custom kernels offer some features not found in the stock CM kernel, like how dual-booting is available for Siyah. But let's focus on battery life and performance for now.
Again, this is not meant to be a flaming thread. I genuinely wish for a conducive discussion on this topic. Lastly let me express my appreciation for both CM and Kernel developers, for devoting their own free time for our sakes.
Thanks!
I'm not sure if this is what you are looking for as an answer but a tweak i've used to give better battery performance is CPU FREQ_MIN. This is the frequency below which the 2nd core is not used. I don't believe you'd be able to use this tweak without a custom Kernel

It helps, thanks Personally I would prefer to try to quantify battery life with different kernels myself. Most phone review sites choose to test battery life by looping a video, however I do not believe this accurately measures battery life.
If anyone knows of an app that loops web browsing I will be happy to test it for myself.
I don't even care for extra 10 minutes battery life. If you want extra battery life don't use the phone. Lol.

But I bought the phone so that I can use it right?
I'm on SOAB right now but I find the battery draining way too quick for my liking. To date, which would you guys recommend? With or without Sense.
I think all the recent stock releases, including MR4, have pretty good battery life. That means Roms based on those, hopefully, have good battery life also. I find AOSP ROMs about 10 to 20% worse on battery life.
Just pick a good rom based on the latest release, potentially with the stock kernel, and you should be good to go. And get a rezound battery while you are at it. Good luck.

Hi there
i have my galaxy for a few wekks now and i find battery on CM9 RC2 pretty bad (underclocked and undervolted)
which rom is recommended for good battery life (and works with siyah kernel)
GPS/WIFI/MOBILE DATA/CAMERA must be working !!
thanks for your suggestions
I was using xwlpo stock, only rooted. Undervolted -25 and set cpu to 800 mhz. The governor was ondemand. The formula of amazing battery life. Now i use jelly bean which wastes battery.

No two people will ever have the exact same setup, and even if they miraculously did, the likelihood of their two phones coming out of the factory exactly the same is infinitesimal.
So a ROM that someone else experiences good battery life with, may be terrible for you or me.

Try rootbox with dm kernel. It has pretty good battery, but like previously said every user is different and therefore will have different battery life. It would not surpise me if this gets closed very quickly.
Generally which provide best battery life?
Also, which individual ROM do you think provides the best battery life?
Stock based roms will provide better battery life than cm based roms.There is no individual rom with best battery life.You have to try them personally.
It also depends upon how many apps are running in background.
A debloated rom will be faster(and battery friendly?).
A kernel is also responsible.There are many kernels.I cannot tell which has best battery life.You have to try them personally.I would suggest to try apolo kernel.

Disagree. I've had much better battery life with AOSP roms on the S2 Vs Samsung-based roms.
OP - there are so many variables re: battery life it's impossible to give a definitive answer/answer for your situation because everyone has their phone setup differently & everyone uses it differently. You're only going to find out what gives you the best battery life by trying out roms/kernels. People who have looked for shortcuts re: this in the past have ended up rather disappointed ('Someone told me rom/kernel X has fantastic battery life but it was crap for me').
I've had much better battery life with AOSP roms.
Just reported this thread, before it is too late If you don't understand why: please read the answer from MistahBungle again.
Best Rom threads are discouraged on xda.
