Certain Rom and Kernels Together Produce Better Battery Life? - Samsung Galaxy Nexus

Hey guys, I am running CodenameAndroid and Francos Kernel. I am getting awesome battery life as I went 25 hours yesterday. However, if I ran Francos Kernel with a differnt ROM, (AOKP for instance) is there a possibility of better battery life?
Do certain Kernels work better with certain ROMs as far as battery life goes?

Yes different combinations produce different results.
Currently testing out new Gummy with the provided Imoseyon kernel. Results look good, updating to 1.0.1 from 1.0 right now.
Here my battery life on my first time trying 1.0 with Imoseyon 3.2.2. Light-medium usage with a lot of standby. Stock battery.

[Q] overclock and slower speeds?

everytime I try an overclock kernal my speeds slow down .. I know that cf-bench and antutu are just numbers and all but .. if the kernals do speed up the phone then I would figure that the numbers would go up from my base numbers due to the performance increase .... but instead I lose about 1000 on each test.
I am currently on Juggernaut and the jugs kernal and I am hitting right under what I was on stock kernal and the stock deodexed ROM I had.
I have it set to 1.7 (1.8 bootloops) thru setcpu and the setting is on lag free currently and I have also tried the on demand setting as well and it was about the same results.
any reason why this would be?
not sure about you, but running great over here check these out

[Q] ArcKnight idle battery drain?

Recently flashed ArcKnight's kernel for ICS and noticed a higher idle battery drain. Not sure whether its normal? Seems that Android OS is keeping the phone awake..
Edit: Running Doom's ICS Rom
Some screenshots:

Previously I had Doom's kernel and the overnight drain was only 1-2%.. Thanks
I have the high Android OS usage too.
Don't know when it appeared. But right now i have whichever kernel i use. Doom, ArcKnight, stock, sirkay. Don't really know what to do about it. Jimbo77 suggested in his arcknight thread that after unplugging the mobile from the cable a quick reboot should solve it. It doesn't in my case.
Not like the battery is drained withing a couple of hours even with the phone idle, but still... the battery life is a bummer :/

[Q] EXTREME battery drain 1% a min

im get about 1% a min drain with just screen on multitasking doesn't change drain off screen is bad as well I had this on the 2 jb roms wicked v5 and paranoid 2+ any fix or is this all jb roms. i changed my modem but i think that reset after i got paranoid. once i was playing a game and the charger got unplugged the drain was so fast that it didn't have time for proper shutdown just the screen got all wavy and boom.
Is an issue in the jb leaks.
Try XquiziT and Frosty. They both have done great in dealing with the battery problems.
Sent from my SGH-T999 using xda app-developers app
Also try flashing CM10.
My battery life problems were cured with this ROM.

Battery Drain even after kernal + greenify tweaks

Hello!
Apologies if people are sick of see threads like this, but I figure I ask for some advice considering I'm only getting about 6-7 hours of actual phone use with only 4 hours of screen on time.
SM-N900T on Jedi Rom with included SaberN3Kernel_KK kernel with interactive governor with these settings:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I've also done almost everything on the battery maximize thread here including greenifying and freezing applications:
http://forum.xda-developers.com/showthread.php?t=2579075
The phone isn't in wakelock so I'm unsure why I'm not getting at least 6 solid hours of screen time.
As you can see with screen on time + spotify I've only used the phone for about 6 hours total which dropped me down to 5%.
Unsure what else I can do at this point, maybe just a bum battery?

I don't think there is a universally best kernel. All kernels try to find a useable balance between performance and battery backup. Some are a bit more performance-oriented, others try to push this balance a little bit more towards battery. Last but not least, the interaction of ROM, apps and kernel is important. So you won't be able to avoid trying out a few kernels with your device (and your usage) and choosing the best one for you.
In my usecase (long lasting battery, only short&light loads, no gaming) I'm quite happy with N0Kernel (battery version). However, my kernel tests were made a while ago and there are more recent versions of all kernels, I think. There might be better kernels out now (for my usecase), but I would need several weeks to be able to make a comparison.
