I think the answer is hidden in your question *hint*
because of the custom rom? maybe i guess, since in the older version of the Custom rom, i have no problem regarding the running android OS. i need to check it back with wakelock and battery monitor i guess

Yup, and now that you have 10 posts you can post in the ROM thread

Okay, I haven't been able to fully understand this so maybe someone can explain it:
I am using KG2 (Villian Rom). It's a Bell SGS2.
Now, I'm wondering if I can change to KI8 or something else later, or will this phone only work on KG2?
Battery right now, is 8hrs with fairly heavy use. I was expecting 10-12, and I have a feeling its the kernel + ROM. I'm thinking of going back to a rooted stock, but I need to know if I need to use KG2?
Can I change the modem/baseband/etc? I don't quite understand how the versions work.
If I can change it, what SHOULD I be running?
Edit: Take a look at the graph... Maybe with this kind of usage, almost 8hr is all I can really expect. If that's true, then maybe we can just answer the question based solely on the kernel issue. I'd still like to know, to be fair.

1. yes you can flash to KI8 if you like.
2. No, you do not need to use kG2 you can upgrade to any rom you like. Each has pros and cons that you needs to try out for yourself.
3 yes you can change the modem=baseband, firmware or kernal to any combination you like.. versions are based on the original firmware version released.
4. best for battery life so far are the latest releases Like KJ 2 or 3.
if you lower the brightness levels, you can extend the battery a little further.

There are many thread about battery life, such as => http://forum.xda-developers.com/showthread.php?p=16973603
One of the first recommendations is to flash the latest official ROM.
As I want to stay as "stock" as possible, I am running a new stock ROM (XWKJ3) and a custom kernel, which is optimized for a better battery life => SpeedMod K2-18-test8.
Here is the corresponding thread of hardcore, the developer of this kernel => http://forum.xda-developers.com/showthread.php?t=1182498&highlight=Speedmod
So, I recommend to flash the latest official ROM (you can get those as non-wipe versions in Intratech's Official Firmware thread here => http://forum.xda-developers.com/showthread.php?t=1075278).
Then test is as "untouched" stock ROM for performance and battery life.
If you are still not satisfied with it, then flash a custom kernel optimized for ... what you mostly want.
Good luck !

Thanks a lot. To flash the kernel, should I use ODIN or can it be done handset side? Which should I do first, kernel or ROM? Or will some of the ROMs have the kernels in? The thread has a lot of extraneous information and I can't seem to understand EXACTLY what I need to do. I've only ever done ROMS through recovery.
If I install a new kernel, it'll most likely work with the current rom (so for example, flashing a new KJ kernel, and a decent modem (is there one?) ) right? Or do I have it backwards?
I don't mind if I wipe or not, everything is in the cloud... One thing I DO notice however, is that ROMs outside of MIUI don't re-install market apps automatically. But that's something I don't mind doing, anyway.

As per above, if I flash a whole stock ROM, will it replace the kernel as well?
Does anyone know wich kernel is the best on the virtuous rom??
Sent from my HTC Glacier using XDA App
New SG2
Home home, it was running 2.3, did a OTA check, it said 2.6 was available. Didnt do it, researched on here first. Noticed alot of battery issues with it.
Rooted with superoneclick.
Flashed Sihyah kernel with odin
Flashed STOShock
Flashed ICS Theme
Charged to 100%, wiped battery stats
Now its my first day running the phone. The battery is really sucking right now. Its been dropping like 1-3% just when i reboot the phone. Seems to drop about 5-10% an hour of the phone doing nothing/turning screen on for 1-3 minutes a couple times to check notifications every hour. I checked wake locks etc, nothing is holding it up.
Now i noticed the version of the system is UCK6 and the kernel is 2.6. Dont these versions have problems?
Is there any other suggests Kernels or roms to flash? I'll even goto a stock rom if its battery life and performance is near the top for all roms. All i really care about is a solid stable long lasting phone with a ics theme and having root.
Perhaps the crappy battery could be from this being my first charge too and the battery not going through any charge/drain cycles yet?
there is no version 2.6 for android....
kernel version and android version are not the same thing. 2.6.x kernel is normal for EVERY version of gingerbread.
what you need to do is have a look at the threads, specifically one called [REF] Known identified battery drainers and check at what apps are eating up your battery.
Doh, what i meant was 2.3.4 to 2.3.6 i believe. And i followed that thread, there are no wakelocks keeping the phone up.
Maybe a better question is. Should i be running UCK7 and not UCK6? Im reading it has some wifi bug that drains down and i use wifi alot
Im thinking of maybe going stock. As long as i can be ics themed.

shostock is a great rom, i have had excellent battery life.
try unnamed 1.3.2 and see if it works out better for you.
Alright ill give that a try i suppose.
Does it matter that im running the latest Siyha kernel? I dont have to reflash any kind of different kernel do i?

a kernel will be included with the rom.
you can flash any kernel you like, but it could be whats causing your battery issues.
I see, i thought you had to flash a custom kernel first before flashing a rom. Because on the SHOstock page for installation it said "You must be running a kernel with CWM."
So i thought i needed to flash a kernel first.
But anyway, if roms include kernels, which im guessing the rom is optimized specifically for that kernel thats included. Whats the point of having them seperate to flash? So you can run a different kernel for some reason after you flash a rom thats using a different one?

You only need the kernel beforehand for CWM. The mentioned roms have kernels included in their package, so it'll be changed upon flash. After flashing the rom, you then have the choice to change to the kernel of your liking. The kernel included is typically the developer's choice for what they think is the best for their rom (perhaps PirateGhost will chime in on this part). Your experience may vary though, which is why you might change to something else.
Gotcha, totally understand. I looked around trying to find a thread that explained the different Base versions.
UCKK6
UCKH7
GWK74, etc,
Im trying to understand the order of oldest to newest release, and what the differences are.
Also, im guessing these bases are official samsung coded items right?

i am fed up from custom roms so i need some good official rom from samsung for my sgs2
any one tell me which rom is best from samfirmware?
region is not a problem in my country so which rom is best and have less bugs then others?
Haven't encountered a buggy stock ROM, they're nearly always stable.
KL1 i my stock backup and is bugfree and quick.
i was having problem of battery from stock i installed hyperdroid now i want original stock
and one more thing is custom roms consume more battery then stock?

Too subjective to say - depends on your usage and the kernel.
Custom kernels can be tweaked more than stock kernels - some tweak for performance, some for battery.
Never used hyperdroid, so I can't compare. On my ROM (see sig) I have Redpill kernel. I compared it once against my stock backup, and got about 75 minutes more battery. But it was hardly a scientific test.
Just flash a couple of stock ROMs and find out how battery life is for your setup/usage.
Generally speaking the latest stock is best .
Generally speaking custom roms are better battery life
Generally speaking battery life is a factor of user and the apps and settings on the phone coupled with usage .
Better battery stats and wakelocks are the starting point .

The best stock ROM, is the ROM that designed for your region.

Not region specific firmware .

i dont have any problem with region because that thing doesnt matters in my country i just want a good simple and less buggy firmware just tell me name of it and also give me reference from samfirmware site
Then go to Samfirmware & choose whatever firmware for whatever region/carrier you want. You can't search yourself why exactly ? (I suspect laziness has a bit to do with it).
ICS Rom
My current ROM is from westcrip :

Resurrection Remix ics v9.6 exclusive XXLPH 4.0.3 Full-Wipe
If you're looking for something stable, fast, no FCs(if you install it correctly ), no orange triangle when you boot your phone(this is not the most relevant because there is an app to remove it, but it was a nice surprise the first time I booted the phone), I would recommend this one.
Hope this helps.
Im on the unofficial lineage 14.1 and while I love the rom so far, battery life is terrible. 4 hours into my day and I'm at 50% battery life.
So I'm looking to go back to a stock Rom that's rooted so I can underclock the CPU and debloat it. Is there a stock Rom that's flashabke through TWRP?
Or, alternatively, does anyone have any solutions to the battery drain I'm experiencing? Flash a rooted kernel maybe? If so, which kernel?

Yes, there is mine builds for both 5121 and 5122, but they are a little bit outdated. Else you can use @lubik1's deodexes.

Try XGen
it boots ROOTED once you flash it via TWRP and is on the LATEST Stockrom from Sony
Fully Deodexed and Debloated!

Fleur phone, 2 months of use, Miui 13.0.4.0 (Global), unlocked bootloader. According to battery settings, android system is using a little TOO MUCH battery, from 1500mah to 2500mah so my battery drains very fast, I even changed my ROM to dot os because of this issue but battery still drained too fast on it, and I turned back to Miui again. do y'all know any fix? Or possible solution? I would appreciate it.
Had same problem. Was fixed with latest eea ROM. 13.0.2.0 android 12 update. SKEEUXM
Could try flashing that rom
