Don't worry, this is not a what is the best kernel question. However it is similar. I have tired all the kernels, speed mod neak redpill syihah phenomannal. With certain kernels such as neak, speedmod, phenomanal, high get a really high Android OS usage. I have read this is just a reporting error however it seems the battery drains alot when in standby. This is not a waklock problem because i dont have any in the battery usage graph and in better battery stats. Does anyone know how to eliminate this in speedmod as it is my favourite kernel.
My last question is what is the best kernel for standby battery drain, i only use my phone around one hour of display time per day. With speedmod i drain around 3 percent a hour without doing anything and again their are no wakelocks.
If you could provide any insite that would be great.
Thanks
It depends too many variables can affect stand by, type of data your on, your signal strength, and such. Only true way of finding it out is to experiment with different kernels and governors. Try use a governor which sleeps well like lulzactive or similar. They have suspend profiles when screen is off, or can achieve something similar with setcpu and setting a screen off profile with conservative.
Allows a good few charge cycles to judge its performance as battery settles.

Yeah i use the KL1 modem with redpill then one im using right now their is only conservative ondemand hyper and sleepy which is the best for standby
I can't answer that as not used that kernel I myself use only ondemand and works out fine for me. Try out conservative and see how that fares.

Ok but can anyone speak to the high android os usage?
Anyone?
After testing several kernels i found that SIYAH 2.6.9 for Gingerbread and Siyah v3.0beta6 for ICS are tremendous on standby and you can see the low Android os consumption (varies between 3% to 10%)
for me siyah workd well with very less andriod os drain but the newer versions ,i am not satisfied cause its heating up more...iam experimenting all kernels ,i was on redpill latest and it workd well,wivout any setcpu,gov,tweaks etc...since 3 days on saiyah 2.6.14+ an its giving good results like the os drain is less than 10.....an iam not on any gov ,tweaks but ill b trying uv,gov twek .....
and yes for reminder iam heavy duty wiv 385+ apps

Its simple different people different phone usage different kernels for different peoples usage .
its usually user apps that are background drain .

Hi guys!
What can I do to get better battery life?
I'm now using devoid #froyo-final, franko kernet 19.4 and SetCPU (480-691 smartass, screen-off: 320-320 smartass). What am I doing wrong?
What are the best profiles for SetCPU? What do you guys use for "screen off"?
What is the best ROM + kernel to use.
I used mik's CM port, but it drains battery kinda fast.
I don't want to have a battery that lasts one week, I just want 48 hours with moderate using.
How can I do this?
Thanks!
Use 480/729 MHz and 480/480 use with the screen off with the kernel minmax 19.4 franco

Dont use screen off profile,it causes wakelocks and reduces battery when idle.

Firstly, when you're using smartass, there is no need to set a sleep profile. Smartass, by default, sleeps at a lower frequency than the max frequency. Just set min and max freq and leave it as is. No profiles needed. The profiler app itself may consume resources scanning for CPU usage.
If you want best battery life, go for Mik's 6.5.7 with the latest franco's kernel/fserve's version of franco's kernel. Do a clean install, clear your battery stats, etc (I assume that you know the drill). Manage your apps and the auto-syncing feature properly and you'll have good battery life for sure. And, pls give some time for the ROM and kernel to get accustomed to your phone. You'll get good battery life gradually.
Good luck
yes do what gkarthik16 said you can also use v6supercharger script
don't use setcpu use cm7 inbuilt feature with smartass governor(I am using smartassv2 governor because I am on mik's 6.6.1)
from settings >application>running services>stop the app or uninstall the app you don't need
also charge when battery is below 20%
Just set it at [email protected] smoothassV2,no need for profiles

For mi, te cm7 ia like the worst rom. Battery line is really low.

What is 'moderate usage' to you, and how long does your battery usually last?
Cm has a bug which causes wakelocks at.first. gets better in awhile

Try AGA-ROM with setcpu 480/729 smartass. You will need new baseband. Here is how to flash new baseband > http://forum.xda-developers.com/showthread.php?t=1149530

Tried it. It sucks.
48 hrs with moderate usage wont be easy. if you play games too forget it in any rom. im on cm7 6.6.1 with franco kernel and i'd be lucky to get more then 24 hrs but i do play lots of games and browsing and wifi on for 18 hrs a day . i found that using automation software like tasker or green power to toggle data or wifi gives a great boost to battery though.
Hey guys
I know its a repeated question but I have been trying several roms with all the different kernels on my SGS2 and the only one that I have found is the Foxhound Rom which gives me a decent battery life. But now I flashed Rootbox because I wanted to have the new TW launcher on the phone...I usually underclock the processor to 800Mhz on Ondemand profile....I installed the latest 1.7 version using the Darknight, CM9 and Siyah kernels and the battery lasts me for just a day of moderate usage mostly because I can see the phone deep sleep about 60-70% of the time? I also dont know if flashing a new modem will make a difference.
Can anyone advise me as to how I can reduce it and possibly get a better battery life? Also I am gonna try the Rootbox with Fluxi kernel as bajee11 uses that on his kernel? But if anyone else is on the same ROM and getting a decent battery life, can you please advise me and also suggest CPU profile that you are using?
All help much appreciated

For ics I use try dark knight 1.8 and it's really good. Are you giving it a few cycles for the battery?

I'm getting really bad battery life on cm9
Any suggestion for a battery friendly rom?
every rom runs differently on each phone so its hard to recomend one. have you tried a different kernel for cm9. change the govenors, io shedules, undervolt or underclock. also depends on your usage and apps installed. cm9 as a base should give you good battery life.
Can't say that there is a "Best" anything. As stated above roms have different outcomes depending on the phone. I am running Gubment Cheeze Build B1.1. I have had great battery life out of it. Extremely great life during sleep. I am hooked to wifi about 22 hours a day. I use bluetooth about 2 hours a day. I do not oc/uv .. or change anything about it... use it like it is right out of the box. If you want to try it .. I am sure you will like it.

Hi guys, as title say, i want to know wich kernel is better for battery life..
I´m on Unlimited ROM, by mv style, wich is really awesome. I´m using Mesa Kernel, but i read that Panic Kernel is good for battery life too.. And performance is also good. So.. wich kernel do you suggest me? Is Panic Kernel more battery friendly than Mesa?
Thanks
My Phone is a Mini Pro
I have never used MESA kernel so I can't compare the two
But kernel PANIC has good battery life... Better than rage and Kamarush v3 (no offense) (just my observations)

Get battery monitor widget from market and test those kernels yourself.
It's better to yee for yourself then to blindly trust
It's easy to do, flash kernel a and leave the phone in standby during the night. In the mornign look at the battery consumption graph in BMW.
Then you take kernel b and do the same with it.
Just be sure to use the same min frequency and same governor.
EDiT:
A ROM also influences battery life. So let's say that for user B MESA has excellent batt life, for user A it might be bad.
That's why it's better to test and see for yourself

That's true....
Personally i try and aim to use a 'lite' rom + panic kernal if possible ....
But most phones give about 1 day worth of work. There are few that exceed that (ultimate? rom by mv_style)
Kernel panic has good battery life

I prefer kernel panic...in every way
I know alot of people ask which is the best combi, but i dont care about that.
im wondering which one really affects the battery more, the rom or the kernel?
im looking for more battery life and i constantly try many roms and kernels to find the best, but its all very erratic so im wondering which one i should change and look for increase in battery life more
tks
It's a combination of both. The core power management drivers lie in the kernel, along with CPU frequencies, governors, and other battery life affecting things. But the ROM is what ultimately makes use of the kernel. If the ROM has certain battery draining features, then it will affect battery life negatively and vice versa. So it's really a combination of both.
