[Q] Best kernel for CM6?

After realizing that I made a mistake by ditching my EVO for the Epic; I returned to the EVO and installed CM6. What a difference! Everything is great so far except for battery life (even using profiles on setCPU) so I was wondering what kernel would provide speed, reliability and battery savings. I'm currently running CM6 kernel and I'm getting around 1250 on quadrant (around the same results of the nexus one with froyo) so I'm happy with the speed so far but I would love some more battery life (I'm getting less than 8 hours with moderate use).
Thanks

What I learn is try a kernel for a day or two. Try another.. you will find one. Not saying do this but this is what I'm doing. Just like finding a rom.. always come back to cm6

Geez, my bad. For some reason I thought I was in the general section.
Can a mod move this thread to the general section? Thanks

Before this gets moved.. all hardware is different. On paper its the same, but what we have learned is that phones respond differently to the software thrown at them. As others suggested, try them out. Snap as well as Kings are excellent kernels. Just find there threads and I can't stress enough to read the op. Most of the questions you have can be found there, as it can be a little cumbersome with all the different versions for some. But yeah, make sure to give it a run for a few days before you decide its not working for you. Your phone needs to get used to it, so basing it off a charge after a few cycles is always a good idea.

Run Snap v7.5 for an increase in speed and battery life.

King's Kernel all the way, and I've tried all the damn Snap kernels.
Mostly, you should be managing your wifi/3g/screen off cpu settings.

I've been using King's #1 kernel after trying (and having issues with) a myriad of Snap kernels. I really like King's and am waiting for #2.

My battery life is stellar

Not sure what you people are doing wrong but I get great battery life running codename android 1.3 and Franco's nightly. Keep 3g on most of the time and use 4g and wifi at home. This is from yesterday, wish I could've let it fully drain but I had to go to work and swapped the battery. This to me represents real world use, played around on the internets, texted, and made a few calls while at work and used pulse heavily after I got home. Kept 3g on while I slept (why do people put it in airplane mode or turn data off?)

the only relevant thing would be screen on time

Your screen on time is very low.

Can someone explain to me why we have 50,000 battery threads? I think we get it! Your battery life is great. My battery life is great. Jane's battery life sucks. Jim can't even figure out how to turn on his Galaxy Nexus.
Stop with these threads!!! And you know what, to add insult to injury... My battery life on the stock ROM destroys what you just posted.

Thanks for the laugh man. I needed it. These threads have gotten so out of hand, it's ridiculous. A Mod should just combine all these redundant battery threads into one giant thread so they can all piss in the wind and see whose goes further.
Sent from my Galaxy Nexus using xda premium

My phone is very strange about battery life, in fact sometimes it lasts 26/27 hours and sometimes, with the same usage more or less, it lasts 15/16 hours

That's pretty good, I can barely get mine to last overnight with literally NO USE, BUT SERIOUSLY ANOTHER THREAD?

Ripping tale old chap.

[Q] Crazy Battery Loss on CM9... help?

I recently updated my E4GT to CyanogenMod 9 alpha 5 and my battery has been dying insanely fast. I noticed immediate drops in battery % at random times, see attached image.

Hey let me talk to you for a sec... dont take this the wrong way but are you the only one in the forum that does not know all ICS roms have terrible battery life until we get kernel source.....Bad battery life is notated on like every thread in ICS.
Its ok man just messing with you but yea until kernel source comes out either deal with it or go back to GB... Oh yea and try and polish up on your ICS knowledge for the future

I dont know about all that I am on CM9 as well and I get the same life maybe a little less than I did on the gingerbread roms. I easily make it through a day with heavy use with battery life to spare. It must be a rouge app.

Hey if you are making it through the day then what the heck are you complaining about and with heavy use.... Come on man! Get Better Battery Stats and figure it out...
I thought you had real issues...lol

I know about the battery issues, but I have never seen a drop like in the screenshot I posted. I don't know if you looked at it, but I have not read of a reason for this to occur. It drops somewhere around 30% immediately

Simple man the kernel sucks life out of your phone when custom kernels start flowing so will your battery life.

I solved the problem.
I have three batteries.

Sorry to bring up a dead topic but since these issues are still rampant and there is no "official" fix thread that I know of, I thought I'd post my findings and fixes that I have come acrossed (I take no credit for any of these methods) after taking these steps, my ics battery issues are gone.
Backup anything you don't want to lose.
Do a factory reset from the privacy settings.
Format internal SD AND external SD under storage settings.
Change wifi advanced setting "keep wifi on during sleep" to never.
Turn off display battery percentage under display settings.
That's it! One or more of these methods fixed my issues, I was having next to all of the problems people are having. Including the random massive battery drops mentioned in op.

Also your notification light and battery light could drain as well.

Which Rom Offers the Best Battery Life on Jellybean?

I know im going to get flamed on this for making 'another better rom for battery thread' but ive been away for two weeks and i see some new roms are out for jellybean, i am currently rocking AndroidMe Cm10 rom, but would like to try a different rom for better batterylife. (its not the best as is ..) i know you guys are going to say every device varies but chances are what most people are getting better battery life on so will mine... so what would you guys reccomend? i really dont want to revert to TeamGummy 4.0.4 (ICS) but if i cant find a better batterylife

well, a better battery life is mostly up 2 the kernel, screen brightness, wireless and network usage, other settings r just familiar of most roms.
though ice has a better battery life than jb, i think
the GUMMY doos have a good battery life 'cause it's using the imoseyon kernel:good:

Noooooo!!

Not trying to flame you but you answered your own question in the OP. Every device varies along with the way each person uses it. I don't have any technical expertise to fall back on when choosing a ROM so it's mostly a trial-and-error process. Flashing a different ROM or kernel is fairly simple, so just experiment and see which one gives you what you are looking for. I rarely, if ever, got the same performance that other users reported when I had my Evo. And lastly, read what other people are saying about a particular combination. XDA has no shortage of people willing to try out new things and let the rest of the community know how it worked. The last 3 pages of a thread are usually the best place to look and see what kind of success/failure rate is happening.

why did you make the thread then?
here's the best rom ever! STOCK

well, in the 2 weeks that you were gone, there have been amazing breakthroughs in development! The battery now lasts almost 2 weeks with on avg 17hrs of screen on time!
*sigh* just look at the kernel threads and youll see, its not like there's 70+ kernels

Stock.

Sprint GS3 WS Rom..Kernel?

Hi all, new to rooting. I rooted my Sprint GS3 running the Wicked Sensations Rom and love it so far,thanks to the team. However my battery life seems to have gone down hill big time. It was mentioned that maybe my kernel needed to be adjusted ( I have no clue when it comes to this, I'm still learning). My question is,how do I "adjust/tweak" my kernel,or is there a better one out there for me? Can someone please explain..Thanks..Phil

Do you happen to know what kernel you are running? If not go to system settings/general/about device and take a screen shot and post. I personally don't mess with kernel settings but this will give someone better knowledge to help you. Also from my understanding the 4.3 update is a battery sucking monster even @dazednconfused bought an extended battery because of the battery drain.

If you haven't made a kernel change then your running dkp kernel. You would maybe ask for suggestions in my thread on best setup or visit decimalman thread in the original development thread to see what others are doing. You could also experiment with other kernels until you find the right setup for your phone. All phones play different with kernels in my opinion so you just need to play around until you are satisfied.

Yeah its the dkp kernel. I've read a couple threads on kernels but none actually say they're great for..... ya know. I know nothing about kernels which is why I was hoping that one of you heavy hitters could say oh kernel??? Is perfect for this rom. Anyway..I'm gonna do a clean flash of WS Rom tomorrow (talked about in my other thread ) and maybe try a battery calibrator and see how it goes..but thanks to you guys..Phil

I wish I could tell you more about setting one up, but I'm probably the worst to ask. I'm so busy playing around with updates and stuff I never even mess with trying to set up. Lots of good people in the wicked thread willing to give suggestions.
