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

Now for my question... Its there or isn't a karnel thats supperts the cm9 perfectly and will improve the battery results?
Thnx

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 =)

Do a data/factory reset, that will solve your problems, type *2767*3855# in the phone dialpad. Backup foto`s , files and stuff before that
It won't let me send the picture it says wrong file extension

Hi there,
If you go to Settings -> Battery - what does it list as using the most battery power?
Edit: You can downgrade to GB if a full factory format/reset doesn't work - you may be another unfortunate recipient of the Android OS wakelock bug.

Start off by uninstalling pointless stuff, then search for BetterBatteryStats.

Skip everything.
ICS sucks on battery life if you are using the stock ICS ROM.
I suggest you revert back to Ginger Bread or Get a new ROM developed by the Xda chefs in the android development section according to your preference.
THis will atleast extend your battery by 20% of the existing performance.
But if you prefer to stick on with ICS, then i suggest you upgade your battery to a higher capacity.
i.e 1900 mAh.

Switch to Cyanogenmod 9 nightly. You can underclock processor to 1000mhz. Battery works great then. Getting almost 1.5 days with moderate use. That's sufficient I guess. Cheers

I'm having this problem too and im using (rooted) stock rom. Its really annoying how i used to get 2 days before update and now i barely get 24 hours. Android system drains 38% of my battery for some reason in ICS, i have no idea why.

try different rom and kernel. I have been using neat rom for few weeks, battery results are nearly the same as 2.36.
Is that c mod 9 an application or Rom

It's a lifestyle choice.
@Mzhaze3
My battery was suffering,not really bad but bad enough to notice it was worse than gb. I have since factory reset my phone (before i upgraded to ics without wiping data etc) and i have noticed major improvements! I am using the 1900 mh battery which helps as well. To sum up a factory reset helped me!
Nice pic btw! :thumbup:
Sent from my GT-I9100 using Tapatalk 2
Well one things for sure the factory reset has made a huge difference. I used to use juice defender and battery still didn't last longer than 12 hours and that's on GB than once i updated to ICS battery only lasted 4 to 6 hours depending on use. Since the reset i have had a whopping 24 hours with moderate use. So i defo recommend it. Thank you gee and thanks everyone for your input x
Sent from my GT-I9100 using XDA
I have major battery problems since ICS update also, (network free, unbranded sgs2) ...... am i right in thinking a simple factory reset could make my battery last three times longer.
Potentially, seems to have helped many so far! It did me!

How much screen time are you using? If you use all day, yes it will drain very fast, especially 3G/4G Data.
For me, I get at max of 3 hours of screen time, and amazing Deep Sleep when the screen is turned off. I am using HydrogenICS, with Thoravukk kernel.
If you're thinking of getting an extra battery, look up on Amazon or Ebay. Anker i9100 Battery. Good quality stuff.
So everyone who's been experiencing battery issues should factory reset?
What will the factory reset to since I have a custom ROM installed?

Noob question perhaps, but how do you go about loading a new kernel for this device? I've done it using an app off the market on an LG albeit a while ago..
I'm having quite bad battery drain with this rom - may try the new nightly ICS if I cant sort it out!!

Flash a new kernel in cwm recovery, or cwm manager. Do not use ROM Manager... Sounds like what you used on the LG
Sent from my HTC Explorer using XDA
I really feel scripts are not meant for ace I mean they are great but for higher range devices
It's just placebo effect + some battery drain + poor management of ram
No offense to anyone
So delete scripts if you have and see

Guys, what stock rom has the better battery life, LPX or LPY?
Sorry about my english.

Not entirely sure about the "battery life" part since it depends mainly on personal usage

Ok, I says bad. I understand this, but I really want say in standby mode.
I does the LPY update yesterday, it looks like draining more the battery.
If you want good battery life, enable system power saving. My phone went from 100% to 99% in three hours.
I would say go for Custom ROM+kernel for better battery life...many options to tweak with battery life....
Try Siyah 4.1.5, and underclock. See if that helps

I agree with custom kernel but in my experience stock ROM provides best battery. It's all very subjective though and this question can't really be answered as you use your phone differently to me.
Just try a few ROM and kernel combos and see for yourself
I get 7hours or more screen time and awesome performance too.
I'm using stock ROM and Siyah 4.1.5, underclocked and undervolted

Have you tried a different charger? Or try an external charger. Then I would get a stock firmware from www.sammobile.com and flash through Odin.

Hi I am 15 years old and i have a samsung galaxy s2 GT-I9100 with stock ics 4.0.3 (exactly I9100XXLPS). It have some issues with (not opening some times) wifi and several battery drain when im playing games ( need for speed, asphalt, etc). I want to play games and surfing but my phone does not keep its battery until night. So I want a rom and a kernel which have no much battery drain, fix wifi issue and if its possible to extend the wifi signal...
Sorry for my poor english.
Thanks in advance.
Hi, i'm also 15 yr old, btw i'm from Serbia(if u know where is it...), if u using cf kernel it has a wifi bug so i suggest u to install siyah or dorimanx kernel... And, i think themes like this(whats best rom, which to use, ...) are forbidden, sorry btw try SuperNexus rom, for me that's best rom for begginers, wish u a luck !
I have to say that ROMs are all about personal preference. Imo you should test out various ROMS to see what's best for you...
That being said, I'm currently using Cm7 on my I777 and it has great battery life (although I suspect it has something to do with turning the second core off and using Siyah GB.)
For Jellybean my preferred ROM is Super Nexus... I got pretty good battery on that one too!

Sorry, but i am not a begginer and i know where is serbia... Anyway i am using stock kernel too now. Also i was using latest jelly bean resurection remix with latest siyah a week ago, but latest resurrection remix version had a very big issue with severe battery drain, so i decided to return to stock unbranded 4.0.3 and then try an other rom. Thats why i create this threat, for not trying all s2 roms.....

How many battery cycles did you let the battery settle for? You should give your battery at least 3 cycles before you judge the life of the battery after you flash something. You can also try CPU spy from the play store to see if your device is deep sleeping. Also try better battery stats to see if you have any wakelocks.

I use RR 3.1.2 and I don't think there is a severe battery drain. Use better battery statsto know what caused it, at the first place.

I give the battery 10+ battety cycles in each rom i try before i report... I will try battery stats and set cpu but i think (because i have tried them in rr) they will not give me the exact reason about my problem. I will try again and post here the results.
Anyway, thank you.

Yesterday i found these fixes on internet... Do you think that this was a cause of my battery drain problem? But why the problem remained (not like in rr, but ramained) after i installed the official stock 4.0.3?

Hardly when idle and ok while using it. 4 - 5 hrs gaming. That's the max you can get with stock batteries.
Im not 15 and I want a rom and kernel that makes the battery last a week.Will be playing games all day,and making the odd call,and listening to music.
