ICS kernel with conservative governor.

Are there any ICS kernels that have the conservative governor included? Battery life is a big issue for me on AOKP and CM9, which prevents me from using them as a daily driver.
At the same time, I love them for being so slick and having the Bluetooth audio issues fixed.
Any help is appreciated.

No, because there are no custom kernels yet that are compatible with ICS.

I think we can fix that one without the custom repacked kernel.
Do you know which governors being used for AOKP and what CPU frequencies?
What I'm thinking about is, we could take the cpu tweaks on my thread http://forum.xda-developers.com/showthread.php?t=1625299, http://forum.xda-developers.com/showthread.php?t=1610741 (all_in_here.zip, there are two cpu tweak files) and make the modification to fit to AOKP.
Currently on these tweak, I'm using 'ondemand' governor as default because conservative governor is not supported on ICS stock kernel yet. By changing the values on ondemand governor, we may get the same result.
(with some other tweaks, I'm getting 24hours now with 50% battery still left on Stock rom/kernel)

Kernels for Wicked Rom & SetCPU question

Hello,
I am using a WIND mobile GS3 with the newest version of the Wicked JB Rom.
And I was just wondering what kernels you guys suggest I can run with it.
In the Wicked Thread they make reference to the "Kernel Thread" but I have yet to find where this kernel thread actually is (lol).
Anyways I was wondering firstly what kernels I can use on the Wicked Rom and what you guys would suggest for the best battery life.
And I was wondering what kernel gives you the best methods for underclocking (below the 384 MHz that the stock kernel gives you) on setCPU.
On a side note: Does anyone have any good profiles to use for setCPU that will save battery life? (I use a lot of screen time but mainly for internet browsing, checking scores, texts and calls, with Wifi (50% of the time) and 4g (50% of the time) on.
Mine are currently:
- Screen Off CPU 702 - 384, Governor ondemand Priority 50, exclusive
- Battery <= 25% CPU 486 - 384, Governor powersave, Priority 51, Exclusive
Thanks a lot!

I use ktoonsez kernel on almost every rom I flash. But I'm overclocking it
All/most kernels are in original development thread. So go there and look for the one that works for you best :thumbup:

Smoocha kernel -- AOSP 4.2.2

Here is a kernel Houstonn and I have been working on. It's based on Faux123 kernel for nexus 4, however, it has evolved into a "buffet" kernel. I keep choosing what i believe is the better interface / way of doing things in a choice of various way or what could give us better battery / performance. I'm trying to maintain a certain balance.
This version is for geehrc (Sprint/Internationnal) with the 13mp. If you have the 8mp phone (E973/E971/E970), use that thread : http://forum.xda-developers.com/showthread.php?t=2229742
I won't link to Faux123 kernel in the nexus 4 for the simple reason that 99% of the people don't read and on these 99% of people, a few will end up flashing nexus 4 kernel which mostly flash by partition number and not by partition name thus hard bricking their device.
Reason to at least try it :
CPU voltage table
Intellidemand and Wheatley governor added
All the block I/O scheduler
TCP Westwood algorithm
Faux123 sounds interface
Faux123 gamma interface (color control)
Newest Prima (wifi) driver.
In-kernel thermal watching
Msm_mpdecision (In-kernel OpenSource MPDecision)
Frandom module loaded at boot.

FransicoFranco Drivers
Thanks for making this kernel, it is much appreciated. I'm wondering where to get/enable the generic hotplug driver and the sound driver by FransicoFranco. Thanks.

I have a sprint lgog and I tried running the eos 4.2.2 ROM for a few days. The battery life was pretty bad compared to the lifeless ROM so I restored back to that. Anyways, will this kernel improve the battery life?

Try it and you will see. I am not giving comment on battery life.
On another note, Version ending with fs have faux sound instead of franciscofranco sounds interface

I've managed to get pretty comparable (not 100% sure) battery life on AOSP compared to Stock Roms. Not to speak for the developer but yes this will increase your battery life. The only thing is that there is a lot you can tweak which will have an effect on your battery life. This is what i do.
Turn mpdecision off. MPdecision is a hotplug driver made by qualcomm that can be disabled in AOSP. As of now its always active on stock roms. I'm still trying to figure out where to get the Francisco Franco hotplug drivers, which are prefered.
Underclock your cpu/gpu - I like to keep my max at 1026mhz and my gpu at 200mhz. I don't notice any significant lag.
Undervolt your cpu
Use a intellidemand/tune your on demand governor
Obviously wake locks come into play as well. I like to use better battery stats to see whats keep my stuff awake.
Finally keep your mobile data off when your not using it
Sorry if I'm just telling you stuff you know, just trying to be informative.

No more mpdecision. Msm_mpdecision in this kernel is different. It's opensource, in-kernel and doesnt force you to 1026mhz minimum freq,

sweet. I was using fauxclock to control my cpu. I am a little confused on msm_mpdecision
is msm_mpdecision the generic hotplug driver by FranciscoFranco?
Is there a more appropriate app than fauxclock to use?
If I disable mpdecision in fauxclock, does that automatically enable msm_mpdecision?

Nope, msm_mpdecision is not franciscofranco hotplug drivers. I had franco driver before and it lagged too much. Also, there is no mpdecision at all. I remove the executable on installation of houcha. Seems as fast as mpdecision without the locking the minimum freq to 1026Mhz.

cool, just for some feedback I feel that there definitely is a difference in my processor states when I enable/disable mpdecision in fauxclock.
When it's enabled, the first core sits at 384mhz until i touch the screen, then the first two cores jump to 1026mhz or 1516mhz.
When I disable it my first core sits at 384mhz and jumps up to 700-1100mhz when I touch my screen, the other cores stay quiet.
In both circumstances I'm using Intellidemand governor.
As long as I'm bugging you, My gpu frequencies are a bit wonky. It goes to 400mhz on boot. When I lower it to 128mhz it will sit at 128mhz and not jump up no matter what max frequency or governor I reset it to.

Try downloading the newest version. fs version have faux sounds, others have franco sounds. I believe faux app read gpu freq incorrectly. If you swipe tab (which is gpu demanding compared to stay to same tab) you will see the gpu freq actually lower.

I'm not sure what sounds to use, does anyone want to explain the differences? (I'm using faux right now but considering trying out franco since I use the franco updater app to control everything)

[Q] Any recommended kernel settings for Jedi? X17 with SaberKernel 38.1

Does anyone have any recommended kernel settings they'd like to share? I've been changing things around a little but I'm too afraid to make any big differences as I don't want to ruin anything. Any recommended GPU clock settings would also be appreciated!
Also, I see people mentioning they're overclocking their phone a lot. Does overclocking on this phone mean it constantly stays overclocked until you change the settings back or does it change frequencies as needed to a maximum frequency that you set?

Hey When you OC lets say to 1800mhz . That means your proccesor can Amp up to 1800 mhz if needed. Your phone will always idle when its a sleep. My setting are 100mhz UC and 1800mhz OC. Gpu is also Oc to 640mhz. I use pegasusq for governor and cfq or zen for scheduler. I also use eco mode . I get very good battery life and performance.

Also...what apps are you guy using for this? Seems most use trickster... Wondering if anyone has experience with others.
Sent from my SAMSUNG-SGH-I317 using Tapatalk 4

I would use whatever the developer of your rom/kernel recommends (which is Trickster most of the time)
Anyone know what eco mode does? I've been looking it up but all I've been getting is this guy's kernel that he named 'eco'
Also, for anyone reading this thread with a similar question to mine I'd heavily recommend using Zen over CFQ as a scheduler because it's much smoother and no jitters/stutters (at least in my experience)
Sent from my SGH-I317

I'm curious what Eco does as well. Tried looking it up, but didn't find anything useful.
Trying out Zen...been getting some annoying hangups and jitters with this kernal. UC 100 OC 1704. And FYI...I've used the stock clocks and still got the same lag and lockups and screen freezes. Also tried on demand gov.
Could it be that ZRAM is enabled? Not quite sure the benefits of it.
Sent from my SAMSUNG-SGH-I317 using Tapatalk 4

Do you have eco mode enabled? Also, maybe you should look into Seeder. It sounds like it's perfect for the kind of problems you're having. Or you could change your minimum voltage from 100 to 200, I heard 100 can be kind of buggy sometimes

[Noob Guide] What is and How to Undervolt

Hello, i wanna share my experience undervolting.
For people who dont know what undervolting is, its the power or energy that the battery send to the CPU with determinate clock speed.
For example:
384 Mhz is the lowest frequency of our CPU, it has a 800mv volt in the stock ROM with stock kernel.
So in theory, the battery send 800mv to the CPU when it runs at 384 Mhz.
The effect of undervolt the CPU is bassically get more battery life and at the same time reduce the temperature of the phone.Less energy send less battery used and less hot phone in our hands.
How to Undervolt
Im running Stock ROM with Ruby Kernel stable.
For undervolt you need a kernel that support it, you can do it in all rom if the kernel support that.
If you want to Undervolt, i recommend you to use Trickster MOD.
You can Undervolt maybe -50mv all frequencies and see how it goes. Some people can even in best cases undervolt -200 mv. But you need patience to test slowly.
DONT TICK SET AT BOOT IF NOT TESTED.
That why you cant:
For example if you undervolt -100mv and if not stable, and you have set at boot ticked, it will freeze the screen and after reboot it will happen again.
After you set the mv for undervolt, download from play store CPU stability test and run it.
It will test all CPU frequencies to see if it is stable.
If you dont get any SoD, congratulations its stable.
My undervolt settings are -100 or in some cases -75 mv and very stable. My battery temp is 30 C°.

Thank you very much

What is needed to undervolt?

Thanks for the info. What are your battery stats after undervolting? How does it suffer other operations of our mobile like browsing or gaming etc ?
Sent from my LG-E975 using xda app-developers app

You need to first make a backup, install a custom kernel, install trickster mod, and from there apply what this discussion is talking about. Good luck!

Bootloader unlocked with freegee and some kernel for your rom that supports undervolt.

Depends on the kernel. I am using Trickster Mod with Viper ZVC kernel. There are other control apps available -- some of them are kernel-specific, some are more universal (Kernel Tuner, Android Tuner, System Tuner, etc.). Look in your kernel's thread -- the developer usually tells which control app(s) to use with it.

Thank you, I'm using AK kernel with UKM and Synapse app from google playstore. Using E-975 (intl.). Can you suggest if I should change the global setting or the individual settings for frequencies ? I had recently (soft) bricked my phone by running benchmark at ~1900mhz CPU and 487mhz GPU (like a villain, I know. Re-connected battery to save it... phew..). I'm really cautious now and I just want it to be less hot and save some battery, that's all. Any guidance would be really appreciated... thanks
