What stock ROM has the least amount of battery consumption? - Galaxy S II Q&A, Help & Troubleshooting

Hey guys! I've been tinkering with other custom roms and ended with CM7. They all consume a lot of battery even if im just on CF-root kernel. So know i'm planning to go back to stock ROM so what would you guys recommend? KI3, KI8, KG6 etc..? I just want to enjoy the stock rom experience before going back to CM7

How about trying out ninphetamine 2.1.3? That is what I have been told. If you get something else better, please share.

You say stock so KI3 or KI8 .
But 90% of battery drain is user.

[Q] Rom and kernel version.

Hi,
I just flash my S2 to MIUI 1.812, can I upgrade my kernel to speedmod k1-t22 ? Thanks!
You can use any kernel.
Regards.

Just want to tell you, yes, I can install any kernel on any roms, but it may cause some problems, especially like the 2.3.5 rom.
I tested, whatever I apply speedmod k1-t22 or ninphetamine 2.0.5 on MIUI 1.8.12, also got a strange problems: the screen will keep jump back to lock screen within 3-5 seconds. The phone also becomes very heat after applied these kernel. Only the original kernel work fine with MIUI 1.8.12. Do you know what is the issue?
Its true that some kernal may not work to well with some roms.the ninphetamine 2.0.5 kernal will heat up as it is over-volted or something like that.the 2.0.2 kernal is more battery friendly and doesnt heat up as much.chainfire is always a good one too cos they stay close to standard but give you root and cwm too

[Q] New to android and galaxy s2 !!!!!

I have a few questions sorry if its a repost but id rather make sure I get a good answer to those questions then any other variant of them.
I got a galaxy s2 a week ago and I feel like the battery life is really bad and the phone heats alot sometimes.... (BTW this is my first smartphone EVER) I was wondering which one of all these custom ROMs out there is the best for the galaxy s2? Which one will give me the smoothest experience with a good battery life and fix that heating problem?
Also, I have the Canadian bell's version so MUGKG2... When I look at ROMs all I see is XXKH3 or XXKE7, etc... Basically how and what version do I have to use/install to get a custom ROM? (P.S I know how Odin works and I know how to root since my phone is already rooted)
And what is the latest Android version possible to get on the galaxy s2? I heard something about 4.0 but I think the latest version possible to install is the 2.3.4 am I right? Also, every ROM is 2.3.4 right? Or do I have to flash a 2.3.4 (or 4.0 depending on the latest version) kernel on the phone?
Thanks for your time and have a good day!!!!!!!

1. there's no exact answer to which rom or kernel gives the best batt life. u should actually test them to see which fits your preference. there are also threads here which does benchmarkings and testing out batt life. try searching for them.
2. when u install a custom rom, it will say on their thread on what baseband version they based their rom. for example, LeoMar's ROM is based on KH3, etc. the rom chooses it for you basically.
3. the latest is 2.3.4, and almost all custom ROMs are based on 2.3.4. no need to flash anything extra
Ok so do I actually have to find a XXKG2 or MUGKG2 based ROM or I can take anything? And from personal experience which one do you think is the best one?
you can actually take in anything (at least your phone's getting an updated baseband version thru the custom roms).
i'm not quite sure how the different versions of the baseband affects my phone. i don't notice any difference in performance actually.
Aight!!! Thanks man. Which one do you recommend?
you can try using the dlev2 rom version 1.2 , its indeed great and also has good battery life

cognition or litening rom can be good choices to start with.
leomar rom gives a lot of customization options because it has a kitchen app on the android market.
My recommendation is that you read some more, get comfortable before you flash anything on your device, know what you are about to get into instead of going on someone else's opinion, the questions you ask are of someone who doesn't fully understand what they are about to do.
It helps when you read a lot, you are able to think your own way through if something doesn't go exactly as planed, else you would have to come right back here to ask a million questions
you can find official firmware here: http://forum.xda-developers.com/showthread.php?t=1075278
as a few posts above i agree what that person said..do a bit more reading before you start flashing. i can remember the time when i wanted to start flashing and rooting and when i did not back up the stock rom the first time i panicked and i did not know what to do and how to get back the stock rom...funny now but back then not so funny..
anyway research play with your stock rom for a while and then flash...for custom rom i would suggest a few...Im using BatistaRom 3.7.7 its the smoothest fastest and battery efficient rom i have used so far...even when i go and try other roms i always come back to this one. For battery as well VillainRom 2.4.2 is one heck of a custom rom and the battery life on that bad boy is wicked..
With regarding kernels again it varies...read the threads of the rom you are interested in flashing and see what people suggest on them..
good luck and be careful when rooting and flashing. any help you need throw me a PM..
Yeah, there are like tons of ROMs and customizations for SGS2 and all major developers are cooking something or the other for our GS2...
Selection of ROM depends only on taste. Some people wants battery life, some people wants only speed and performance. So ask yourself, what kinda ROM you need. One built from scratch, one modded from stock, AOSP?
I use GingerMod Vanilla 0.4. Suits my taste

[Q] which is the best combination of kernal ver and Rom for good battery life??

which is the best combination of kernal ver and Rom for good battery life??
i am using
baseband :- XXKI3 (2.3.5)
sensation rom 1.8,
ninpetaine kernal 2.1.3,
with this i m getting 15-20hr battery backup with decent internet usage(1hr to 2hr) on 3g.
can u suggest me best combination of kernal ver and Rom for good battery life??
If you're looking for good battery life, try Lite'ning Rom v6.1
A KI3/8/KJ1/KJ3 type frankenstein rom combined with the latest 2-13 speedmod kernel.
No messing, close to stock, rooted, excellent battery life.
ki3 + speedmod k17
Thread closed.
Best relies on so many variables flash as what's best for someone else isn't likely to be best for you! Make a backup and flash away...............

Galaxy S II - Woes

Hi Guys,
Okay. I am a noob and I hate being a noob, and when I registered for the site I watched the noob video. Whilst I did do my research on xda, androidforums etc. I feel I still need your assistance before I go on to ruin something.
Phone: Galaxy S II
Location: Australia
Network: Vodafone
Kernel: XXKF2
Rom: Litening Rom v1.5 XXKF2
Android Version: 2.3.3
Mode: GT-I9100
Symptons: Low internal storage, drained battery, when charging or in use, can get very warm near the camera lens.
I've actually had a great run with Litening Rom until one day I woke up and my alarm went off for work. I went to turn it off and the battery was so hot I could've started scrambling some eggs. In a state of panic, I turned the switch off and the battery charge for 6hrs was 5% - wtf. Long story short, I've searched and found many threads with many different unofficial responses. I'm to the point where I'm deciding to go back to stock or to another rom. Most of the download links I've searched on XDA seem to be invalid (i.e stock Kernel XXKF2 and Litening Rom v3.2).
In anycase, do I need to:
1. Download specifically the XXKF2 kernel? Or can I try another? If so, can anyone direct me elsewhere as god knows I've tried.
2. Anyway to remove rom on its own? I've got Odin etc.
3. Can I also clarify that when I rooted the phone to the Litening Rom, does that change the stock Kernel? If not, then perhaps I just need to goto point 2 above.
Any assistance would be grateful.
Thank you.
Hey mate.
When you flashed the custom ROM you would of also changed your kernel.
I would suggest trying Siyah kernel, I've used it and I had great battery life.
That should help sort out your other issues too
Good luck!
Youre talking abouth odin and lightning rom so youve rooted and flashed allready......so your a bit noob-off,but as above said try another kernel or better....flash an other rom.
Download some other roms, reboot in recovery, flash them try it for an day....with outh installing your app's , install your app's when youve got an rom of your choice/like's see what the battery drain does and the heat development at the back......try it greatz mike
