Stock Kernel firmware 2.3.5 best battery life. - Galaxy S II Q&A, Help & Troubleshooting

I Did a test, on 2.3.5 on the xxki3 and xxki4 , with the speedmod kernel s2-k2-16 and de Siyah kernel 2.1.1 and mu battery life is much better with the stock kernel.
What is our opinion. Did the test with the same setting and after a clean install.

Whats this go to do with original development?

I think that the stock kernel is very good and more stable than any mod kernel..

[Q] Which Kernel and ROM combo do YOU use?

I've been flashing a multitude of kernels and roms since I got the phone last week, and am wondering what combos people are using.
Performance wise the best combo I have gotten is Stock Bell ROM + Lulz build 11 xxkg3
Currently I am using LULz XXKG3 Build 11 and Lighten'ning rom 1.5
What would you guys say it best for performance? What about Battery life?
I get great battery life and performance with the combo in my sig

I always use Stock ROM (siggy) and CF rooted kernel and Stock kernel to remove YT.
Regards.
Criskelo Rom and ninphetamine 2.0.1 kernel, and for me works good. I am using Criskelos romm for the las 5 month (in SGS1 and now in SGS2).
Cognition 1.30 and ninphetamine 2.0.1
Leomar 2.2 and Nimphetamine 2.0.2, very stable and great battery life. Hope this helps!

Can I flash any kernel?

I have a rooted galaxy S2 with a stock 2.3.5 ROM and I want to flash a different kernel. What kernel should I flash and can I flash any kernel?
Thanks.
Yes, you can flash any kernel as long as you are on a Stock ROM.
Now which one you want depends on you, if I were to suggest one it will be SpeedMod by Hardcore. A great Kernel it is.
I love simplicity.

[Q] Best ROM for battery and performance

Hi,
Im looking for a ROM which uses less battery and has good performance. So far i've got VillainROM and WajkIUI. I could'nt find the 2.3.6 version of VillianROM and i think its not out yet. My SGSII is stock 2.3.6.
Also, i read somewhere that there is a 'counter' for custom roms and once the counter goes up, you lose warranty. Is that true?
you will get a best perform rom and batt friendly if you join to it a good kernel and modem but I suggest you checkroom v4 wish is EXCELLENT without too much tweak and removing all the samsung junk so you can still download it again with an app that cam when you flash the rom
and actually I'm on syiah 2.5 gt+KL1 modem and very fine at the moment no battery drain for nothing and everything is smooth as butter
if you read carefully you will not brick your phone and everything is reversible to 100% stock phone actually sue no worry for warranty
there is a counter if you flash an insecure kernel or rom but you can reset with a ''micro jig'' that you can buy on ebay for less than 4$
and with the new clockwork mod app you can bypass the counter by the way and you save the time to connect to the computer and flashing with odin ...

Sorry, Im a noob to all this. What do you think is the best kernel and modem for my rom? I downloaded and flashed XWKK5 and the kernel is
[email protected]#2. Dont know how to find the modem lol sorry
you just have to download any kernel from this site there are few very good !
the kernel you have on it is a stock kernel
you have to follow the direction if you want to root(install cf-root)that match your version, make a backup and download titanium backup (verrrrry good app)
siyah 2.5 gt (the one I use)
speedmod (I used it very good batt life but feel not as stable as siyah) and you are a gunea pig with this one
DK very good based on siyah kernel with a bit better battery life maybe
you have to match your current version wish is kk5
for the modem is the base band in phone info and its should be KI4 at the end if I'm ok or KI3

Well I can tell you already,using any .35 kernel is going to kill your battery...its main objective is performance and speed where else .32 kernel is tailored towards battery with some performance...
Have you tried updating your kernel using 6.6.1 because im getting good battery life using 6.6.1
Bit if you wish to remain with .35 kernels I would recommend a-series 7.2-kang
I sometimes had connection problems using 7.2 so I switched back to 6.6.1

adfad666's CM7.2.0-RC0 Ax .35 gave me terrible screen lag and battery performance. My batter was drained to 50% in just 9 hours without using the phone.
adfad666's CM7.2.0-RC0 A8 .32 with Goldenleaf kernel drained my battery by 10% after 9 hours + WIFI was on an running. The ADW interface also is not as sluggish.
Just an observation mate.

That is just a bogus string hardcoded in CM7. It will show that no matter which baseband you actually have.
Ok
Thanks, i have the N2 Build and gsm work so i think i have the old baseband.

[Q] should i must have to change the kernel if i change the ROM?

hi guys,
i wanna ask you senious guys that,should i have to change the kernel each time if i want to change the ROM of my galaxy s II or any kernel will work with any ROM?
kindly assist me in this matter.thanks.
What type of Rom are you trying to flash?
Most custom roms include a kernel so you you will have to refresh back to your preferred kernel.
Or you can open the zip file and replace the kernel of your choice as long as it matches your firmware version, ie GB kernel for a GB rom etc.

any kernel may not work with any ROMs...almost all samsung firmware versions has got its own versions of Kernel.
In SGS2 normaly custom kernels are used for rooting your phone, like CF-root, whcih are made for almost all the samsung firamware matched kernels, you only want to pick the one matching for your ROM.
It is also seen sometimes advised to back up your Kernel, this can be done using a tool from Market called "Ktool", at a worst scenario, when your installed custom kernel giving you a treble you can restore the previous one.
EDIT : you are already on a custom ROM as well as Custom Kernel. both have got their newer versions alredy.
checkrom is now on V6, and Siyah kernel is now on v2.6.14
Well your still on gingerbread and an early kernel and early checkrom. There are many roms and kernels you can try the best for battery life us what works best for you and only you can figure that out with testing.
Try out an ICS Rom if you haven't done so already and there are now custom kernels for that as well.

I meant the kernel that is already included with the rom when you flash it. So just flash the rom and you don't need to install another kernel after it.
Here is a link to the Resurrection rom:
http://forum.xda-developers.com/showthread.php?t=1436854
Hope this helped you
If you flash a rom it replaces the kernel you've been using with that of the rom you're flashing...
Soooo
Eg cm9 + siyah
If you flash a new nightly it'll replace siyah with cm9s kernel so you have to flash siyah each time.
Think that makes sense..!
