I know, your magical settings really blow me away. Especially the underclock to 800MHz is really genius.

It won't do sh*t, as you can't drop the voltage enough to make it worthwhile.

Yes, again, "your" settings make it magical. It has been tested that 200MHz is the "sweet-spot" for speed (amount of time an app/service takes to complete it's task) and the amount of energy being used doing that. If it doesn't "hurt", why use it after all?

Read it, now what? I don't see any "proof" that 100MHz is beneficial?

Enough has been written on this subject already. It's simply "best" to use 200MHz as the minimal frequency. But hey, if you want to use 100MHz, be my guest.

"Stay away from using 100mhz during screen-off or screen-on states for three reasons:

It seems 100 mhz uses more power than 200 mhz. According to tests, 100 mhz accounted to 1 W / GHz and 200 mhz to 0.7 W / GHz, when both the cores were online.

200 mhz can finish same task faster compared 100 mhz and thus hit deep idle soon.

200 mhz is the 'sweet spot' of frequency in SGS II. ie, the frequency used in the calculations based on the optimal energy to run (Eg: In Milestone it's 550 MHz). So , 'energetically efficient' frequency for our CPU is 200 mhz."

All these magical kernel settings are utter cr*p. You can reach the same results with almost any kernel if you set the phone up using the same variables. There is no magic kernel, there are no magical settings.

Underclocking is the thing which will have the greatest impact, period.
[Galaxy S II General] ram3n:
Then, take a better look at his results & settings, specially at his frequency scaling : 100-1000MHz. Wow, he can achieve to reach more 7h30 screen on time too. So, the question is rather : we don't see any proof of disadvantage of using 100mhz as you said.

Well, so you're here again with your irony style to claim that my settings are actually bulls***, aren't you ? Have the decency to say it without going in circles :)

Sometimes, as my sensei told me, pratice becomes more important than theory. I just hope you've tested byyourself all you said before giving those advices.

AFAIK, I did it my self, trying both min frequency scaling 100 vs 200 Mhz since several months, and therefore, I dare say 100Mhz with 775mV works just great considering to batterylife and general performance with my usage. That's my personnal experience that I'm trying to share here. Nothing else, nothing more.

Anyway, that's all your honor to defend your ideas. I see you're very keen on tuning CPU and UV. Why don't you open your own thread to share your experience ? :)

People are smart enough to make their own choice in conscience.

Does it compatible with cm9 based? so after flash this, there's should be new profile for Touch presets in xxtweaker? correct me if im wrong. currently using xxtweaker 0.3.9_b4?
[Galaxy S II General] ram3n:
Yup, It should works great with CM9 since it's compatible with all AOSP/AOKP ICS ROMs.

However, It has actually nothing to do with Touch profiles in xxtweaker. :D

Fluxi issue

Hey ram3n , when i using fluxi kernel .. why sometimes work very well and great battery .. bt sometime will suddenly freezed my phone when before getting a message/call , and when i drop my call .. will get stuck/freeze on the end call there :confused:

What's the issue mate ?
[Galaxy S II General] IonutP:
Does this tweaks remove the wake up lag?
[Galaxy S II General] ram3n:
Well, I see bro. In your case, it's possible that the UV settings may be a bit "Extreme" and borderline for some tasks, hence the freeze.

You can try to +25mV for each steps and see if the unstable issue persists.

:D

BTW what ROM and kernel are you using ?

No at all mate.

Anyway, I haven't any wake up lag with my actual ROM + settings. ;)

It's depending on what ROM you're using.

Hi guys i'm experiencing some freezes with the fluxi settings in OP...

I had already used that settings on NEAK and everything went well,maybe should i raise my bus freq?
[Galaxy S II General] Hk.Tang:
Remix Ics 2.2 with fluxi kernel :)
[Galaxy S II General] Pfeffernuss:
False yet again, Rom/kernel/magical settings are all irrelevant.

Our phones take at least 0.65 seconds to wake-up, when not being charged. No matter what Rom or kernel you're on, it will always take this long.

For some people this might be "instantly", but for most people this will seem like a long time.

Please stop making BS-claims.
[Galaxy S II General] nehalem176:
Reported and hopes your extreme uv setting will give even better than before: link
[Galaxy S II General] ram3n:
Guys,

I've experienced some freezes too when calling with two latest Fluxi... Seems that It's a little more Energy-hungry, even on my S2 and the only way to solve it is to increase the UV values by +25mV for each step from 100 to 400 MhZ.

Yup, You can also try to raise your bus freq to see it still persists.

Anyway, I'm already trying the brand new Dorimanx kernel. First impressions are pretty good. Much much stable than previous versions.

Let's see more deeply how it goes :p

Will report of course my incoming new settings with Extweaks.

Cheers.
[Galaxy S II General] ram3n:
Thanks mate. Waiting then for Fluxi's Beta5 :D
[Galaxy S II General] Fustigador:
thks ram3n, very helpful tips not only related to kernel´s

a must read thread :D
[Galaxy S II General] butterfry:
Blablabla, please get out of this thread you little troll ! Only you call ram3n's settings "magical", he never did. Plus, no matter how you interpreted, we can't say 0.62s is a significant wake-up lag :D

So please take your business away, or as said before open your own thread and stop posting BS claims here.

THANKS !

@Ram3n : yep ! Waiting for your Dorimanx settings to see some improvements !

Big up bro ! :)
[Galaxy S II General] ram3n:
You're very welcome bro ! I'm always glad to see people thanking me for finding my tweaks usefull.

Be sure I'm doing my best to share my experience and with the aim of having a good autonomy & performance ratio. :)

Yup mate, don't be afraid, I will. Meanwhile, enjoy your actual settings :rolleyes:
[Galaxy S II General] Blondiepowa:

Obviously this guy has free time to persecute ram3n in his thread instead of giving more interestings tips and advice... What a waste of time ! :rolleyes:

Anyway, don't pay attention to him, and let's focuse on this great tweaks topic. Fluxi + RR + those tweaks rock so far ! Can see my battery sounds to fly away :D
[Galaxy S II General] ram3n:
UPDATE :

Add DORIMANX KERNEL 3.4.X & EXTWEAKS SETTINGS :

- CPU settings for Extweaks

- GPU settings for Extweaks

NB : Tested and so far no issues such as :

- No lag when playing music screen off

- No lag, no freeze when SMS or Calling

Thanks for you confirmation mate.

Now enjoy fully your beast ! :D

[Galaxy S II General] raza_k:
Wow these settings are amazing thank you so much ram3n. I've NEVER been able to uv my gpu settings as low as they are now. I did have to up the 500-800 cpu voltages by +25mv and the 100-400 by +50mv like you mentioned and it fixed everything.

Quick question though I want to put the script files into the etc/int.d folder but I can't find it in my internal storage, can you help me out as to where it is? :o

I'm using the latest fluxi kernel with your settings btw and of course rootbox rom is actually really cool, all the ics roms have looked the exact same and I hate that :(. I remember back when we were all on gingerbread every rom looked completely different. Now the only ics roms that look different are miui, rootbox, paranoid a little maybe because of all that tablet mode stuff.

Once again thanks! :D
[Galaxy S II General] ram3n:
Hey you're welcome too mate!

To access the init.d folder you have to use not a ordinary application. Use one for example like RootExplorer which allows you to go in system folder.

Yup, I think the same. PARANOID has a amazing dev with his tablet mode featuring. Really nice. :p

Cheers!

[Galaxy S II General] raza_k:
Hi again the problem is I don't know how to copy files to that folder through RootExpolrer because those files only show up on my phone and I tried mount r/w still doesn't show up on my files when i connect it to my computer. Also you show in the system/bin folder to change the file chargemon settings, but that file doesn't exist on my phone even when I look in RootExplorer. :o
[Galaxy S II General] superleeds27:
Sched_MC

For battery, do you suggest enabling or disabling?
[Galaxy S II General] ram3n:
Okay I see mate.

Fist of all, my example was taken from a HTC screenshot and is only made for showing you how to set 755 permission :D

Then, It is very easy :

- Download my scripts and copy them into your sdcard

- Open Rootexplorer > go to Sdcard folder where you put them

- Choose Copy for each script

- Then naviguate to etc/init.d folder and paste them

- (If Init.d doesn't exist, just create it manually)

- Don't forget to set 755 permissions as I explained in the OP.

That's all ! Im' sure you can do it :p
[Galaxy S II General] ram3n:
No mate, I suggest you to leave it disabled as It is actually redundant with hotplugging for our settings. No real advantages.
[Galaxy S II General] core_x:
I can't find some of the settings you posted in #1 in extweaks (downloaded from Playstore). What do I have to do to see them?
[Galaxy S II General] ram3n:
Maybe because, I was on Dorimanx 3.4B when I wrote this. :D

Anyway, It's time for me to update for newer Dorimanx 3.4C I guess :)
[Galaxy S II General] bouighil:
her i'm, i'll test your setting in dorimanx kernel and see if it will give me more battery then siyah
[Galaxy S II General] WasseemB:
My device have been able to handle the undervolting same as your voltages and its perfect but there is something about the xxtweakers setting and extweaks ones i tried both and the device just seems to freeze.

Any idea which setting i should leave out and try ?
[Galaxy S II General] ram3n:
Ok :

1. Try to wipe app data, and then reinstall them.

2. Try to raise voltage bus table.

fingers crossed :)
[Galaxy S II General] THE RED BLUR:
@ram3n

Hi mate have u tried the latest dorimanx yet?

Is ur settings compatible with version c?

I noticed a script download should I use this?

The latest siyah has fantastic deepsleep.

Using Resurrection Remix AOKP ICS version 2.3 powered by Siyah 3.3.2
[Galaxy S II General] raza_k:
OK thanks alot it worked haha! I use to use scripts like v6 supercharger etc when I was on checkrom v6 but I use to use the script emulator so I'm new to this.
[Galaxy S II General] WasseemB:
Im using dorminax kernel atm so i think in extweaks voltage bus table is the ASV group ?

Because returning it to 3 seemed to do the trick :P

Thank you very much, gonna try if i can push it up more

Oh and from your experience what do you suggest dorminax or fluxi for better battery life ?
[Galaxy S II General] bouighil:
i've tested the last Dorimanx and i'ts the worst kernel ever for me, he eats my battery even with your tweaks ram3n :(

Now i'm testing Phenomenal 5.5 extreme and he seems good, verry good till now :)
[Galaxy S II General] ram3n:
He He He, Nop. Welcome to ICS experience. So much better than GB in all the way. CheckRom was a good ROM, but it's outdated now. See the futur and leave the past :)

Yup, set the bus freq ASV group to 4 Step if your device can handle it for max batterylife.

You know it is difficult to separate them, knowing that they are actually my favorites.

There are always pros and cons mate.

Fluxi is very impressive in the ability to configure all the "tweaks" modes regarding the CPU/GPU/BLN/Governor/Bus/hotplug/etc, and remains very stable.

Dorimanx also starting to become very rich in number of parameters, and Extweaks is a fabulous app to use for tweakers like me.

I would say that the first one is a little be more "stable" than the second one, but remember that they are still both beta versions. So, the best is yet to come.

It's hard to tell you what is the "best" battery saver, as we all have different way of using our S2, so It can be biaised, and what is better for me could be worst for you, and so on.

ATM, I'm using latest Dorimanx and have to do more cycle of charge to give a conclusion. :D
[Galaxy S II General] ram3n:
Hi there,

Yup my settings are still compatible with 3.4.C, but I need to update them as soon as possible. :D I will do it tonight or tomorrow morning mate.

Anyway, i didn't tested Siyah, but I guess newest featurings GENTLE_FAIR_SLEEPERS and ARCH_POWER help a lot.

Cheers

PS : If you are talking about customs scripts, yes you can use them.

I quote DroidPhile for best explanations :

So, for better batterylife, It is recommended to set up to 100000 or 120000.

From what I've tested, Conservative + Noop is more battery saver than Ondemand, and performance isn't so much affected. So, It's a very interesting combo.

Try it and love it. ;)
[Galaxy S II General] superleeds27:
Yeah gone for it. After resetting my fuel guage earlier. Dropped from 40 to 8, then jumped upo about 15. let it fully discharge.

- Better batterylife, better performance

- Less RAM usage through zipalign.
[Galaxy S II General] SachsenPowl:
K thx!

Will it try at next RR...

but last time i used fluxi Kernel got strange Battery Drain with this Kernel -.-

On Siyah @ BatteryProfile all was fine.. Didn't understand this !?

Everyone hyped the fluxi, best DeepSleep, Less Battery Drain etc... But on my Phone it suxx...

I will try the new fluxi, on the new RR with your tweaks and if it will not working, i go crazy!
[Galaxy S II General] ram3n:
hahaha nop mate.

Give another chance to the latest beta, It should work fine.

otherwise, your device is maybe allergic to it ? ;)

fingers crossed.
[Galaxy S II General] WasseemB:
Am currently using rootbox rom 1.2 and there is start-up tweaks such as zipalign apks, enable sysctl and scheduled tasks do they differ much from your script? Shall i disable them and use your scripts ??

Oh and how is Pegasusq going? i heard it gives better performance compared to other governors but never heard anyone talk about the battery life ?
[Galaxy S II General] grzesdroid:
What do you think? Abyss 2.0 or fluxi xx02

tapatalk@ SGS ||
[Galaxy S II General] ram3n:
AFAIK, Abyss 2 U is already outdated and no more update as you know, but remains a great stable kernel.

Since I love being in tune with the times, I would say that I recommend now Fluxi as it has many tweakable settings.
[Galaxy S II General] ram3n:
Yup, you can disable them if you use my scripts. :)

Anyway, Pegasusq is a very already proven & performant governor... But also controversial, as it was made initially for quad core.

Some say that it's actually useless for our dual core, others say that a well tweaked pegasusg can perform very well.

To my experience, pegasusq doesn't improve much more batterylife than Ondemand if you wanna an advice.

You can stick to it if you've found good settings and are happy with it.
[Galaxy S II General] kitecarl:
Thanks for the informative thread. I've determined I can't uv to more than 850 at 200 mhz without causing instability. I have not however attempted to lower scaling to 100 mhz yet. I see there are varying schools of thought on whether this is worth putting in or not.

My phone appears to hate the noop scheduler! Same exact settings for uv, cpu scaling, etc work fine on cfq and sio but the minute I change to noop I get a soft reset! Really surprised by this since I didn't think a scheduler could have this type of impact! Any insight here?
[Galaxy S II General] ram3n:
You're welcome mate.

Yup, I must admit that your "issue" is very strange. A scheduler shouldn't cause this kind of impact.

By chance, are you running any other "scheduler" scripts which can cause such interference ? What ROM & kernel are you using ?

If it doesn't matter to you, stick with SIO which is great too, and 850 mV @800mhZ as it's your custom min freq scaling settings.

If you're happy, it is useless to change mate. :D
[Galaxy S II General] shizuku:
On your OP you recommend Ondemand + Noop. Which one would be better for battery life?

And the CPUidle mode: standard in fluxi on idle, but would AFTR+LPA be a better choice?

Tried the newest Siyah with some UV, but CM9 with some undervolting was better for battery life, as was Abyss.

Now trying Fluxi.
[Galaxy S II General] ram3n:
For better battery life, It's clear for me that Conservative + Noop works a bit better.

Likewise, you should set AFTR+LPA for better deep sleep.
[Galaxy S II General] Soul_Ripper:
Sir,

I have a problem. Some time my device goes into deep sleep & it doesn't wake up so i have to reboot it. Its nt too frequent but it happens nearly too times a day

I did scale my voltage up upto certain steps but with no success

I m on wanamlite rom and using abyss ultimate kernal.

I didnt install any script just undervolt & uc it and changed the governor and i/c scdlr..

Hope i can get help
[Galaxy S II General] ram3n:
Hi there,

I see your problem mate, and also what causes it.

In fact, some others users have also reported the same issue of sod. It was caused by the abyss 1.2 U version.

Flash an older version and it should be okay.

Otherwise, go for another kernel bro!

Hey i have some noob questions. First of all i want to thank you for the great work and support.

I am using fluxi ksrnel. Changed the parameters of cpu like yours and have to increase three times until my phone stops freezing. Everythings good but there are another option that i dont know do I have to change like maximum cpu frequency and maximum cpu frequency suspend and minimum cpu frequency and minimum cpu frequency suspend. There is voltage table i didint know if i have something to change. On the gpu parameters i use yours and everything is ok. I dont have SOD, but before 5min my phone reboots like i was typing this post. Did you know what can that be from and sometimes i got the feeling that my phone freezes everything is so laggy that i cant do anything but after 1min everything is ok? So do I have to change anything because I am n00b in the section :)

Thank you in advance and sry for the n00b questionS
[Galaxy S II General] ram3n:
Hey,

You're welcome noobie with your noob question don't be ashamed :rolleyes:

From what you're are saying to me, I think you have to be sure firstly that you've got the right UV values your device can support.

Then, if it still doesn't work, try to raise the voltage bus frequency too.

For you, About the cpu frequency suspend, I would recommend just to set like this :

Min suspend : 200 Mhz

Max suspend : 500 Mhz

And for others cpu scaling_min_freq and scaling_max_freq : 100 and 800 Mhz like me.

Hope, it will works well.

Cheers matey :)
