Best karnel for cm9 - Galaxy S II Q&A, Help & Troubleshooting

Hi guys...
I recently install the cm9 4/4 rom
And its amazing! So far I dident get any bugs..
But I do have one problem, the battery is so weak.. Like every six hours I need to rechargh it.
So what I wanted to know is what karnel that supperts the cm9 well will give me better battery results?
Thnx alot!

I peronally like cm9 stock kernel best, better check what services/apps are running in the background that consume much power!

I'm using the original karnel that I got with my sgs2..
Is there a stock Room for the cm9?
Can you give me a link please?

Mate until you do some research, don't flash anything. Unfortunately you don't understand what you are talking about

Mate battery life won't magically improve by flashing an alternate kernel / ROM. There are tons of reasons which may affect battery life on a ROM, and you must first determine what that is before you move on and experiment. Before moving onto a new kernel, determine what is causing battery drain using apps like CPU Spy (Can determine if your phone is entering deep sleep or not) and BetterBatteryStats (Can determine kernel wakelocks which prevent the phone from going into deep sleep). Also, what is your usage pattern? On extremely heavy usage patterns, 6-8 hours is below par, but not unbelievable.
Unfortunately I would agree with mattisfaction at this point of time. Stock ROM for CM9? When you install CM9, you get the CM9 Stock kernel. Not what came with your phone.

Well...
I see I got much more to learn :-/
Well thnx anyway, ill come back after some more research =)

Best rom ?

Im new to the galaxy ace forums and was wondering if the regulars could help me figure out which rom would best serve my purpose of battery life, speed and stability. It would really help me out. Thanks !

Use a stock rom if u want battery life (i ussually use KS2/KS9)
Use a custom rom with overclock if u are searching speed. More speed involves more battery drain.
Use a stock rom if u are searching stability, they are the only which hasn't bugs.
The three things together are impossible. Speed will drain ur battery. Custom rom involves bugs.
Try the latest stcok indiam firmware and several others, like 2.3.5 or 2.3.6

There is nothing like best rom

I think no one can say what the BEST Rom is for you.
You have to try out for yourself.

Totally agree. Battery could be better

When do you think ICS is going to be released; should I install an ICS-based ROM?

When do you think ICS is going to be released for the Note? I've been holding out on installing custom ROMs, but if it's still going to be a while, I might as well do it.
Also, which ROMs (ICS) are the best? Is the battery life better or worse? Are there a lot of bugs?
I never try any custom Rom yet but usually there is always bugs on custom roms. I just suggest u wait for the official ics.

I'm using the unofficial. Then stripped out every last bit of bloat before installing apps. Vastly better than stock and only one rom flash. Plus the -k holokernel. My guess is ICS official won't come out until late May or June at the earliest. Even after that there will be custom roms based on it so I'm not going to bother until a good custom rom based on the official ICS comes out.

There are some great custom roms. Much better then any Sammy crapwiz stock rom.
Try them yourself. You will be glad u did. Just read and follow all instructions. Exactly

Be nice. Everything in any kind of forum is subjective.
I could also say you dont know what you're talking about if that's my opinion.
Im a senior software engineer who simply does not have the time to even look at Roms.
Does that make me "nuts?"
ICS seraphim is awesome. Works very smooth and is polished. There are very few known issues with most of these roms, nothing that should be a deal breaker for anyone.
Apex launcher is infinately better than touchwiz.
Also, ics stock revamped is another great rom ported over by smartguy044.

Reading will tell you all of the features in less time than it takes somebody else to look them up for you, type a response, and for you to read their response. Trying out the roms yourself will show you everything and you can figure out your own likes and dislikes of every ROM.

And then the time to set up the rom, try different roms, discover compatibility issues, find out which apps cause battery drain..etc...
It can be much more time consuming than what you're describing.

I can get 2-3 days, maybe even more if I keep the power off. But less if I actually turn on the screen and use it.
What are you trying to find out here? The battery on the Note is what it is.

NO ONES BATTERY WILL BE THE SAME AS YOURS...THE ONLY WAY TO KNOW IS TO TRY IT YOURSELF!!
sorry about the caps, but this question just makes me crazy...

Try CheckROMv2 + nimphetamin3 kernel
Sent from my GT-I9300 using Tapatalk 2
Hi,
It's not a silly question - there are far too many custom roms with custom kernels. The combinations of these add up to an awful lot of flashing, not to mention then running it for a few days to get an idea on battery and performance. It would probably take weeks!
Anyways, for me, i rooted my stock UK rom using Chainfire 6.3, and then froze any bloatware apps i didn't use or want using Titanium Pro. This is now giving me better battery life than previously and running nice and smooth.
To give you an idea, i had around 25 hours moderate use with around 4.5 hours screen time.
Hope that helps a little. I'll probably try a custom rom sometime once things settle a little more, though i'm really really hoping for Jelly Bean now.....

[Q] Choosing the right ROM/Kernel 4 performance

Hey every1
so I wanted to fix a SGS3 of a friend of mine who isn't so much into modding. His phone lags like hell, keyboard and calls, just everything. I'm personally on a GNEX and couldnt stay one minute with a phone in this condition.
Well i thought about Supercharge his phone, maybe also changing the Kernel before, but leave the rest stock... but maybe it wont be enough and I'll have to flash him a ROM.
Now I ain't got a SGS3 to flash me trough all kind of ROMs in order to see for myself what works and what not.
So what I'm asking for are some recommendations. The ROMs for SGS3 are all different then then these on GNEX...
There are many and i want to reduce my options to lets say 3-4 ROMs and some kernels...
Anyone?
Thanks

On my personal opinion, I'll suggest CheckROM.
I've used it as a daily all round rom juiced with latest siyah kernel.
No lags and no un necessary batterydrain.

The rule on the Galaxy S2 forum is that you are not allowed to ask which ROM's are better, which is basically what your thread is asking. This is not allowed as everyone's opinion of a ROM is different, and what performs well for one person may not perform well for you. You must try these ROM's yourself, with different kernels for better performance and battery life to find the optimum setup for you. Sorry but that's the way it is.

Actually if you ask for consumption. I think ics is way more superior in saving battery than JB. There are so many reasons for that. Check the change log on wikipedia you ll come to know. Screen causes more drain on JB. Im also agree with the person who first answered your question.

I've personally noticed I can't get as good battery life with JB as with ICS. I use the same settings, and the same apps, but ICS seems better for me.
On the other hand: some people got great battery life with JB, so I also would recommend to try both versions to compare. Performance-wise (and the wonderfull features), JB is the best
