What kernels/methods are available to uv this phone to improve battery life? And any postings of actual numbers that have worked well for others?

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 .

As the titles states, i would just like to make this thread for everyone willing to come in and share their experience with different roms and preferably show some screenshots of the graph and screen on time. I will be uploading mine shortly

i've discoverend that the best rom for battery performance in my scenario is DarkyRom HD - i've tried so many ICS based roms and all the promises of "better battery performance" have not yielded anything more fruitful than what darky provides - as a matter of fact, darkROM HD is the only rom that actually charges my battery while i use it.. other just discharge regardless of whatever tweek and power saving setting i set on it
I've used HydrogenICS and it's one of the best for battery life imo. The base is AOKP
CM9 with N.E.A.K kernel - amazing battery life.

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.
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.

buy another battery and carry it around with you
OK, I realize that everyone has a different idea of the best ROM and/or kernel, and I fully expect to try out a few different ones to see which is best for me. However, I am hoping that I won't be irritating anyone by asking for suggestions on where to start. I don't need a lot of extra features, but I do like to be able to configure as many settings as possible--that is the main reason I chose Android in the first place. I also want to maximize battery life. Based on my experience with SlimBean on the Nexus S, it and SlimKat will be definite contenders, but which others should I consider? And are there any specific kernels I should look at? It will be a couple of weeks before my LGOG arrives, so there should be fairly stable 4.4.2 based ROMs by then, but I don't mind using 4.3 ROMs if they will provide better performance. I have been using a Galaxy S II for the last several months, where NeatROM is the only real choice if you want good battery life, so I'm a bit out of the loop.
I have been having a similar issue with trying to maximize performance and battery life at the same time. I have found that using android 4.3 really does make a huge difference in battery life and it makes all the animations, I think, look more fluid. Now as Kernels go, I cannot recomend one in particular, but look for one with eco mode or just change your processor setting with Trickster mod. I use only 2 cores, the ondemand governor, and keep my frequencies between 1026000 and 1512000. Hopefully this helps.
