[Q] Battery Issues !! SOS - Galaxy S II Q&A, Help & Troubleshooting

When I have upgraded the ROM do I need a custom kernel along with it? Or it is included in the ROM? I’m using cynogenmod 10 i.e jelly bean 4.1 but the battery backup is awful  I get less than 8 hours on standby.. I’ve even turned of google now but no luck.. so I suspect the problem could be my kernel not matching ROM or something else .. not sure.. I am lost…

Use BetterBatteryStats from play instead of guessing. It can help you find the sources of increased battery drain.

Cyanogenmod ROMs come with a custom CM kernel included. U can also flash other custom kernels if you wish.

Siyah kernel. Most popular kernel for sgs2 at the moment. Unified kernel, can be flashed on any Samsung based rom or aosp roms like miui and cm7.

Well, it depends on how wisely you undervolt and also make use of many no of features this kernel offers. I haven't used miui. So i don't know if something specific, like media scanner running endlessly or something that's causing battery drain.
I'm on gingermod rom. With siyah, battery is really good. See this (my own ) post about some of the features for saving battery in Siyah, that the dev has incorporated. http://forum.xda-developers.com/showpost.php?p=19231855&postcount=9615
Reviving an old thread.... now that MIUI hmade the jump to ICS.... which kernel do you recommend?

[Q] Problem of Random Reboot

Hi friends Iam currently on Simplistic Rom v4 with S3 theme and siyah kernal 4.1 ..
I have been facing an issue of random reboots and rapid battery drain..
I tried to changing the kernal governors to lulzactive and scaled down the cpu speed to reduce the rapid battery drain but everything in vain..
Is there anyway to solve this issue? Can i flash it with some other kernals like speed mod to solve this issue?
Earlier I was using my stock rooted ICS and CM 9.0 in dual boot mode and i never experienced such random boots and battery drain..
I love this rom so much coz of its kies support,S3 UI/apps and Iam in no mood to change the ROM..
Someone help me out guys...

Thanks now trying
But what would be the real problem?
Is the siyah kernal responsible for battery drain as mentioned in the Zedomax's youtube channel or would be the bugs in System frmawork of simplistic rom?

Anything could be causing your battery drain.
Easiest fix for now if to flash a another kernel.
If the problem then persists,, There will be need to find out what's causing the battery fascism.

Since you already tried Siyah, then
1. Dorimanx kernel: forum.xda-developers.com/showthread.php?t=1617219
Or
2. Dream kernel: forum.xda-developers.com/showthread.php?t=1788021
Both meet their dual boot needs. Both support Extweaks too

first if the rom is not optimized to wrk on any kernel then u will face all these issues, and also playing around with CPU and GPU settings will not give u any good battery life, unless ur sure of those settings.
hence the stock settings are always best with any Custom Kernel for sure

Confusions should go away once you start reading mate! Not just guides, search and read other members' experiences too!
You need a custom recovery to flash NeatROM. For that you have CWM recovery that comes with Siyah. So no need to change kernels.

[Q] Games with CM and other custom roms

Hey guys,
One of my friends wanted to try out a customrom for his S2, cause he wasn't satisfied with the performance of the stock rom.
So i installed him cyanogenmod from 19.04.13
Now he is sad cause it looks like there are some issues with mali-driver so some games (for example this stupid and his favored game Simpsons TappedOut) will not work with cyanogenmod.
Are there other customroms who have no problems with these mali drivers?
Or is there any work around?
Or does he have to choose between Customrom without some games and stockrom with bad performance?
Thx for your answers, guys

Try alliance as its custom sam rom with loads of thing to change .its 4.1.2 but best of both worlds. 4.2.2 iv tryed. Wasnt impressed.

dungeon hunter 4 real racing 3 simpsons tapped out etc all games are working without problem
Instead of naming your own favourite roms, just advice to flash a custom rom based on stock JB It has the best performances (don't know which version the guy had before?) because of Project Butter, and there are a few, some named above me, who can be customized. Just read the threads and try some.
Why not. Whats the harm in that. Whats wrong with what I put. Did put about custom sam roms too. I spent alot of time looking for a rom that has the lot.

There is no harm, but I meant the choice is up to the OP. I've tried the latest Alliance too, and I personally didn't like it. What I mean is the advice is the Samsung-part, and the choice of the specific rom is up to yourself
Can I ask ....what rom are you on atm. Alliance is cool. And ok I understand what you ment. Also I did put about the custom sam rom. :thumbup::thumbup:

I like the concept of Alliance very much, but I experienced some lag and slower responsiveness than other Samsung-based roms. Now I'm on Omega.
I know No offence.
Choosing between Omega and Alliance is tough mates! I chose Omega because I love the walking droid boot animation!

AllianceRom is based on ICS, so this is no option.
OmegaRom looks nice and ill ask him if he wanna try, but i have seen that the Rom has abot 600MB.
Looks like there is much Bloatware included.
main reason to change to Cyanogenmod was to get a clean, small and fast Rom.
Anyway, it's his decision what he wants to have and im sure Omega is still much better than stock.

Nope, Alliance is for JB also mate. Check again..
Stock JB 4.1.2 roms all have huge size, not because of bloatware, but because of the preload partition and new features like multiwindow, etc.

Miui 3.11.22 (v5)

Hey guys!
I am trying to use MIUI V5 3.11.22 (the latest one) on my I9300, but, seems to have some "lagging" you know?
it's not smooth and cause lags on screen changes, like entering and leaving the settings, etc...
I used to love this ROM when I had an Defy+ but now it seems to be just a lagging ROM...
It's so beautiful.
how can I use that? how can I make that without lags?
Do I have to flash another kernel? What kernel?
What you guys using with it?
Thanks!
Guys I need help.

what rom and what kernel threads are not allowed on xda as per the rules. you should try all the kernels yourself depending on which the base of the rom is.
