Hello there,
First of all thanks for sharing these important tips/guides for getting better battery life on our devices.
I just installed the latest version of Resurrection Remix ROM with the latest Siyah Kernel for ICS. Using the ExTweaks app I modified the given values on the previous page.
Now what else I should do? Are the new settings going to be applied automatically in each reboot? ( I remember when I applied the UV settings previously on a GB rom with Voltage Control app I had to set them as boot options and in each reboot "Default settings applied" was shown on status bar).
Thanks in advance

Geko, without magic config I wouldn't be herebattery consumption was already low using hyperdroid rom and the redpill kernel, heard about undervolting but it all seemed confusing and dangerous ... so I never bothered until I came across your thread where I was encouraged to take my first step in undervolting. It was so successful I noticed the difference there and then. 1650mah would give me 1 day on battery and 4-5 hours screen on time, but as I'm a very heavy user, thought why not extend the awesome results and make it extreme... yes I use the 2000mah battery now. Another tip to everyone would be to remove bloatware off the phone, it helps alot
Thank you geko, I have also referred many users to this thread to achieve this without any risk involved .....coz someone already broke the sweat for us
Hope this helps someone, anyone and everyone
That's great to hear mate.
Perhaps you could put a link in your signature then it would be easier for everyone to get here...
Also, I've been meaning to ask someone to do this. Since I don't have my S2 anymore, I cannot take screenshots of ExTweaks with the settings applied to add to post 850. I think this will help users a lot who are adjusting the settings for the first time.
Any chance you could do that for me??
With ExTweaks the settings should be applied automatically.
With Voltage Control you had to set them to apply on boot first in the app.

What do I put in my sig, the hyperlink?
Sure, I'd be more than happy to do so... but I use voltage control, is that okay?

No worries mate, have fun eating those special nan-dishes.
Thanks.
These settings (GENTLE_FAIR_SLEEPERS and ARCH_POWER) are for both kernels but as I said the difference is that for 3.2.7.1 you can't set them from ExTweaks app, you have to make a "trick" with special script located in /system/etc/init.d directory. For 3.3.2 is easier to activate them. According to your question which is better - just try them, check them and decide which is better for you. Some forum members claim that 3.2.7.1 is more battery saving (friendly) than 3.3.2. It is subjective issue so I am not convinced and still testing them both - no clear results yet.

Does the kernel you sent me work with gingerbread? I'm on gingerbread, just flashed it and it's not booting up.
So far getting good battery....
Using slim ics with siyah kernel....
That too flashed yesterday... First test straight away....
Had 2 freezes and had to reboot....
Now on relaxed uv....
I think I'll definitely get more battery life once the kernel is well settled....
Anyways thanks

Downloading, flashing, setting up, letting it settle.... i really don't have time on my hands to do all that. i thought it was app related at first, then found out it was kernal which didn't seem too time consuming and now it's rom related. Honestly, if i had time Geko, i would have done it, I'm Sorry. Unless extweaks works with the gingerbread version of siyah kernel if there is any, then I can manage.
Yep... tried the relaxed as well... still hanging and reboots...
I had tried the preset "power saving" settings in extweaks and that was running fine... so then kinda merged the power saving settings with the relaxed settings till as far as its fairly stable... so far had one hangup till now... but unfortunately the battery life doesn't seem to be exceptionally crazy like you people seem to be getting :-(
Currently as follows...

And at last the final battery stats would be... slightly more than 4 hours screen on time... now this was all with wifi and barely any data... with data on and wifi off I'm sure will have much less juice for screen to last that long...

315MagicConfig (previously "mycfg")
Universal UV tweak to help you easily get an great improvement in battery life, Gingerbread and Ice Cream Sandwich Compatible!
First step for any Undervolting beginner.
INITIAL STORY
Due to receiving endless requests few months back for me to post my "MagicConfig" for SiyahKernel and as I'm typing this right now I still have to send out 20+ PMs every single day on this subject. So I have finally decided to make a thread for it, now it can be discussed and found here without needing to contact me.
Obviously I only wanted to do this after extensive "real world" testing myself and MagicConfig's initial user's confirmation that it works astonishingly well, since then it has been picked up and loved by many many users more. IT TOOK ME OVER 4 MONTHS TO MAKE SURE THIS CONFIG WOULD BE COMPATIBLE WITH ALMOST ALL SGS2s. HOWEVER, PLEASE READ THE WHOLE POST CAREFULLY BEFORE TRYING TO APPLY THESE SETTINGS.
Now, what you will find below is not a script of any kind so there is no need to download or flash anything. All you need to do is simply input these values into Voltage Control app which can be downloaded free from the Market.
I have done my best to test the configuration and to my knowledge it should work on most of Galaxy S2 devices out there. It is designed to bring balance between smoothness and battery life, I have spent over 3 months (since the betas) going through all of SiyahKernel releases to find the perfect combinations of Schedulers and Governors that are included within each release of the Kernel. If you do have issues or if you needed to make alterations of any kind to make it work for you (not including reducing voltages further), please report this here. Thank You.

MagicConfig SiyahKernel ICS Tweaks - http://goo.gl/ykgQ0[/B]
Requirements and description below!
UV Settings for other kernels can be found in this thread by ram3n:

6+ HOURS BATTERY LIFE IS TRULY POSSIBLE!! NOT JUST A MYTH!!
http://xdaforums.com/showpost.php?p=21852140&postcount=2
READ SOME FEEDBACK FROM CURRENT MAGICCONFIG USERS!!
http://xdaforums.com/showpost.php?p=23081634&postcount=3
----------
* CURRENT PHAZE (MagicConfig ICS):
MagicConfig v1.0, tested and working with SiyahKernel v3.2.7.1 and v3.3.2!! Earlier versions of this kernel should be suitable as well.
* REQUIREMENTS:
You need to be running SiyahKernel (latest is always recommended) and have the eXtweaks application installed.
SiyahKernel ICS by gokhanmoral development thread is here:
http://xdaforums.com/showthread.php?t=1555259
eXtweaks app is here:
https://play.google.com/store/apps/details?id=com.darekxan.extweaks.app
* INSTRUCTIONS ON WHAT TO DO NEXT:
Go to this post and follow the settings there:
http://goo.gl/ykgQ0
----------
* CURRENT PHAZE (MagicConfig GB):
MagicConfig v0.3.2, tested and working with SiyahKernel v2.6.11, SiyahKernel v2.6.12 SiyahKernel v2.6.13, RedPillKernel v1.2, v1.3 and N.E.A.K. 1.3.3x, 1.4x, 1.4.1x and 1.4.2x.
Have to say, best balance between performance and battery life with this config can be achieved on N.E.A.K. Kernel. Earlier versions of any of these kernels should be suitable as well.
* REQUIREMENTS:
Any of the above mentioned kernels, just do a search on XDA and you shall find them.
-_-_-_-_-_-_-_-_-_-_-
* GOVERNOR & SCHEDULER MATCH-UP:
SiyahKernel
- BFQ / ONDEMAND
- NOOP / CONSERVATIVE
- SIO / SMARTASSV2
RedPillKernel
- DEADLINE / SLEEPY
- NOOP / CONSERVATIVE
- SIO / HYPER
N.E.A.K. Kernel
- BFQ / ONDEMAND (some have reported slight lags)
- NOOP / CONSERVATIVE (with Lionheart tweaks)
- NOOP / LAZY (best balance so far for me, maybe it sensed my own lazyness lol) (SCHED_MC and EXT4boost enabled)
----------
* CPU:
Undervolted Range / 100Mhz - 1400Mhz
Battery Saver Setting / 200Mhz - 1000Mhz
+ VOLTAGES:
- 100Mhz - 900mV
- 200Mhz - 900mV
- 500Mhz - 950mv
- 800Mhz - 1000mv
- 1000Mhz - 1100mV
- 1200Mhz - 1200mV
- 1400Mhz - 1300mV
*** RedPill Kernel can't handle these voltages on some devices, if you get freezes or reboots please raise all voltages by +25mV ***
* GPU:
114Mhz low / 267Mhz high
+ VOLTAGES:
- 850mV low
- 950mV high
----------
* OTHER INFO:
Mainly at the moment I just stick to NOOP + ONDEMAND on N.E.A.K. 2.0.4x, running CyanogenMOD 9 and CPU at 200Mhz - 1000Mhz.
As I always say though, these voltage settings are a safe stable base and could be tweaked to your liking once you get experienced with undervolting.
Also can I ask you kindly not to post this config in any other threads, instead if someone asks for it then just direct them to this thread please. Thanks!
-_-_-_-_-_-_-_-_-_-_-
* SCREENSHOTS (this is what it should look like after all parameters are set):
----------
* NOTICE:
That's about it. If you want to save even more battery juice then just reduce the highest CPU frequency down to 1000Mhz or even 800Mhz.
Also, I found that having the lowest frequency set to 200Mhz improves smoothness quite a bit and doesn't impact battery too much, of course it's also slightly more stable. Potentially, this can conserve even more battery life.
Do not have multiple CPU / Voltage configuration apps installed at the same time, you will most likely get conflicts.
If you start having issues (screen going black, freezes or reboots then raise all voltages by +25mV) then everything should work as normal. If it doesn't, then raise by another +25mV.
Enjoy the smoothness everyone. As always, feedback is greatly welcomed and is very helpful to others. Thank you!

* FURTHER INFO:
I know that time will come when you will want to use Lulzactive governor which can be tweaked to your liking using the Lulzactive app. Here is a thread by Stifler69 which has some excellent settings which you can start with:

That was after a day of medium-heavy use on SiyahKernel v3.2.7.1 and CM9 Nightly 08-06-2012 (flashed in the morning, so didin't even let the ROM settle). Easily 6 hours screen on time guys, I'm sure you will agree that it could easily stretch past 7 hours if I let the ROM and kernel settle.
-------
That's it really, one other thing I want to mention is that I do not use auto-brightness (unless I am outside). Usually my brightness meter is at around 40% all the time.
If you guys could see how these settings go for you, if everything works as it should then the above information will be added to the OP.30Configurations comparisons, battery run results.
My recent battery run:
This was on:
CheckROM V6 + N.E.A.K. 1.4x + MagicConfig v0.3.2 + V6 Supercharger
As you can see in the screenshot I was on 50% battery at that time, so by the power of addition we can conclude that 6+ hours screen time is very much possible and isn't a myth.

Recent kernel comparison report:
Massive thanks to It_ler for conducting the following comparisons (28-02-2012), please read the whole report carefully to avoid unnecessary questions.[/SIZE][/U][/B][/CENTER]
Results for SpeedMod / Phenomenal / N.E.A.K. / Siyah / RedPill / stock kernels
Everything is specific to my phone, my "normal" usage and my home location. Most values are exact results, but some are rounded. I usually have wifi, synch (three email accounts, calendar and news), Google Talk and Skype on.
For all custom kernels, I was running on Frankenstein XWLA4 ROM (Modem: XXKL1).
For stock kernels, I was running on the corresponding stock ROM.
Always using the Samsung's standard / stock 1650mAh battery.
- For Siyah, as it has many, many configurable settings, I have changed nothing - just default settings.
- For N.E.A.K. I tested VR schedule, Lulzactive governor, only enabled sched_mc and the rest unchanged defaults.
- For RedPill kernel, I tested completely default settings (deadline / ondemand) without any change.
- For RedPill (MC, noop/conservative), I tested geko95gek's MagicConfig v0.3.1 settings with noop / conservative on 200-1200 MHz (no UC or OC, only recommended/safe UV).
- For RedPill (MC, dealine/sleepy), I tested geko95gek's MagicConfig v0.3.1 settings with deadline / sleepy on 200-1200 MHz (no UC or OC, only recommended/safe UV).
- For RedPill (sio/conservative) kernel, I tested completely default settings, only changed io sched to sio and governor to conservative.
- Just tested RedPill rev1.3 with different io sched / governor combinations (and geko95gek's MagicConfig), and added its results.
Here are my current results:

(*) In order to get a value, which allows to compare test results with different screen on times for mixed usage battery tests, I tried to „normalized“ the battery loss per hour with the following formula:
loss*(1-screen): battery loss in % (per hours) * (100% - screen on time in %)
So, it would be the battery loss in % (per hour) for the screen off time.
That is how a kernel with the same battery loss per hour will get a better/lower value, if it has more screen on time. (And the other way round.)
RedPill rev1.3 has got best battery savings with sio/conservative on my phone, even without any additional UC/UC, etc.
Subjectively, it feels a little bit laggy/not as smooth as in other combinations (e.g. sio/hyper).
So, my first impression of this kernel was proven: Very stable kernel which is highly configurable to fit every demand - for performance and battery life.
Thanks again pongster for that great kernel.
And thanks to geko95gek for his MagicConfig which gave me enough confidence to test out some UV, io sched and governor changes.
Looking forward to test new versions of that kernel ...

5Configuration user feedback.
Just some feedback received from users of MagicConfig:
From boromxed
"Hi,
This is to inform you that your settings are excellent.
Have tested them on Siyah 2.6.7 /2.6.8 and 2.6.9 with Omega B&B 10.2 rom and, it works wonderfull on all.
Very smooth and very little battery drain.
For information battery drain during night time over an 8 hours period (Wifi/Data/Background Data on off) is less than 2%.
I even got 0% during one night (battery level at 35% at 12 pm and still at 35% at 08:00 am);
Congratulations, mate"

"So i tested out your config, and oh my do i get amazing battery life! whenever i go to school id have it drain down to about 92% after my first class which was roughly 1 hour and 35 minutes, and thats without touching it, this time it only went down to 98% and that was with music playing too some of the time! Thanks man! i read about your 0.3.1 config, whens that coming out? lol"

"Hey Geko,
Used your settings back in 2.5.2 and battery life was AMAZING.
Wondering whether you have v3 settings for 2.6.1 out
Cheers"
Great to see you've created a thread on your configs geko!!!
Been using your configs since around v1 and it has always provided me with the best battery life & performance. Keep up the good work

Did exactly what you suggested with siyah and voltage control.
Made a huge difference. About 1.5hrs more screen on time.
Previously used cfroot KK5 and setcpu to UV/UC and by 4.5 to 5 hours I'd be looking for a charger.
Thanks a million for this. I have smoother, better performance all round and what is a record for battery performance for me.
I'll be sticking to this setup for sometime now. Unless neak really is better.

All is working good now, unbelievable battery life. Many thanks geko, you have earned my "thanks" and a mention in my signature

More to come....5Hi everyone. I just want to share this script I created. It has both andreilux's gpu settings and magicconfig by geko. Though the undervolt in the script is higher so it is a bit more aggressive and if it runs fine on your phone. It will give you the best battery life on Siyah 2.6.11. Goodluck
Just flash the zip like usual.
Some Notes:
It is recommended that you remove boot settings especially if you have the start up service boot by voltage control. Though this script will execute later than boot vc if you have it. It is still better that you just remove any boot settings done on vc.
