[Q] Best Kernel on G2 with MIUI

Trying to find out to anyone using or not using MIUI which kernel is the best for the G2, i am also trying to find out what SetCPU profiles work best with that kernel from personal experience.

Curious myself.
*bump*

I'm on the latest Pershoot and battery and performance is some much better than stock kernel. In fact, battery life is possibly better than Sense! I OC'd to 825-1497 MHz screen on and 245-368 with the screen off. I get the occasional (once in the few days I've been running the ROM) refusal to wake up, but I heard that's a bug in CM (which MIUI is based off) to do with OCing + screen on/off animations. I did, however, get tons of freezes and reboots when my maximum frequency was set at 1516MHz, which seems to be above the threshold my phone can take.
Anyway, that's my experiences, YMMV!
Hope I helped

I have been in MIUI_1.07.15_OsiMood v1.0 (just flashing to 1.2)
atleast in 1.0 FM-radio on desire z didn't work whit Streamline5 and Pershoot 2.6.35.13 kernels. on default kernel it works.
i dont think i'm going to try out those kernels in 1.2... any kernel suggestions whit smartass/conservative governors and hopefully working FM-Radio?

Which version of MIUI are your running?
I'm currently running Carpes' Miui Version, "Light Gets Lighter"
The kernel I use is Eugenes' Streamline5 Kernel which can be found here Streamline5
He has a MIUI version but for some reason doesn't run well so just download the Original.
Here is the download link if you have trouble finding it > kernel download <
As for Setcpu settings
Max/Min
Main:
1000/800, smartass
Profiles:
Screen Off: 384/245, smartass
I only find the need for a screen off profile because I like my phone kept on low hz and it's pretty much the same as battery charging profiles if you have the same hz
Its also recommended not to underclock lower then 245 as it will cause a lock up or freeze being unable to wake up due to slow processing speed

I was coming in to say just about the same thing. Funny because I'm usung the exact same SetCPU settings. Streamline5 is the absolute best way to go.

Happy to hear and yes, Streamline5 is awesome!
If Both our reviews still don't help then maybe this will. Another great thing about Streamline5 is that it will still run smooth even if you leave it clocked at just 800 alone and maybe squeeze a little more juice out .
Reason I scale it to 1000 is I like the little speed boost it gives me

Yes, got Tiamat kernel runing in my MIUI, and looks like everything is working fine, even FM-radio...
has all the necessary governors, and goes up to 2ghz

[Q] Best kernel for MIUI

I am currently using MIUI 1.7.29 Osimood with the Tiamat 1.04 kernel, and I am wondering what the best kernel is for battery life. I am also using the V6 supercharger ram script. I am running my CPU at 960mHz at the moment, using the smartass governer. I also undervolted using vipermod, 960MHz at 950mV.
My choice consists of the latest Pershoot, UmaroKernel 1.06 or Tiamat 1.04
What differences would I see between those kernels, are they noticeable for a regular user?

Sorry man, but wehre do you find the vipermod for desire z? http://vipermod.tiamat-dev.com/faq.php it's not compatibile with desire z/g2....

Uh...what's wrong with the kernel it comes with? Can OC to 1.5GHz stock ya know. Battery life is great with it too. People always want to flash something weather it be a radio or a kernel.

damn straight,
1) pershoot is a sense kernel? (i am proabably wrong but i have never tried this kernel)
2) umaro kernel i found had issues with wifi, high underclock freq (leading to poorer battery life), but fun if you have the time to tweak voltages and fast!
3) tiamat kernel i found had issues with sleep of death/random reboots on wakeup couldnt test it past that. (setcpu was set to screen off was: conservative 125min -345 max and would still crash)
if you are up for another kernel, i am now using this kernel (streamline5)
no voltage tweaking (pretweaked) but it has good batt, speedy and stable cant ask for much

Pershoot is actually for non-sense roms. The downfall people have with it is lack of governors. Some don't mind, some want variety. I've had great experiences with Pershoot's kernel and it's the baseline that all others are compared to (not to mention the foundation of almost ALL G2/DZ kernels).
Umaro's just needs to have voltage tweaks done manually but on the plus side - keeping the voltages normal (not UV) allows some people to reach higher OC speeds. It keeps the processor from bottoming out due to insufficient voltage which can easily happen when you UV. The main issue is with the Greased lightening governor - it's new and still a bit buggy.
Tiamat 1.0.4 is outstanding. I can sit all day at 2+ GHz (not literally, see: Chernobyl). I personally have an issue with the interactive governor but other than that it's my favorite kernel (Umaro may take that soon, once greased lightening is perfected).
Basically you just need to try out a few and see which you like. There is no 'best'. Most kernels will work with any ROM (Sense being the only exception).

Bumping a thread that is relevant to my interests.
It's about time for me to jump ship from an outdated CM ROM and try something new like a MIUI ROM.
With that said, I'd like to read more opinions & experiences from people using the various Kernels AND how the latest radio (the one released today) is working for them. I'm just trying to get the optimal experience here
Speaking of MIUI would anyone mind telling me some differences between OsiMood's ROM compared to the official MIUI-US ROM (or even DarkSpadez ROM)?
Thanks a ton guys!

I downloaded the official rom . . .then ignored it downloaded osimood and iv been using it since. Osimood is a lighter rom, which is always a good thing, unwanted languages etc are removed for a smaller faster rom. Also he preinstalls tweaks like an adblocker and extended settings mod.
Kernal wise iv been looking for the same info as you but couldn't find it. So I eneded up trying them all:
- Eugenes streamline5 is a nice kernal, preundervolted. Only probly is its not being updated so will become redundant.
-Tiamats kernal allows over clock to 2ghz and seems to support higher overclocks stably where other kernals can't. Except battery life has decreased with recent kernals
-Umarokernal this is the kernal iv come back to twice and am still on. It allows overclock to 1.9ghz and is kept updated by umaro. Performance per frequency seems as good if not better than most and osimoods miui runs smooth with this kernal on 800ghz with scarey governer (which saves battery) Another plus for me with this kernal is the scarey governer which for me definatly provides the best performance per battery ratio.

I'm currently running MIUI 1.8.5 with Eugene-Streamline 5 Kernel with the latest radio update Vision_Radio_12.57.60.25_26.10.04.12.
SetCPU with Governor ondemand provides me with better usage, power and responsive time then Smartass or Interactive.
OC to 1.2ghz
Battery life, about 30hrs with the regular 1350mah.

i just got 40 hours with similar setup but i use virtuous o/c daemon instead of setcpu
big fan of streamline5 and hope that it will get updated eventually

How do you get the virtuos o/c daemon?

Its basically like an automatic setcpu (which can't be changed on the fly) built into the rom, its in virtuous unity roms

What sleep profiles are you guys usein. I seem to have rebooting issues with any kernel I try unless I go to a sense rom. I've tried the vipermod now to see how it goes
Sent from my T-Mobile G2 using XDA App

But how do you get the virtuos O/C daemon to work on MIUI?

You can download it threw rom manager. Even with that kernel I get reboot issues. I assume its cause system ram isn't being cleard fast enough. I'm gonna try 100mv increase to see if there's a difference.

[Q] AOSP, Kernals, and a Newbie.

I am fairly new to this scene.
I recently got an EVO and decided I hated Sense so I went looking for a stock ROM. Light and fast. I have tried Cyanogenmod7 and Salvage Mod. The thing is, the battery life I am getting with these ROMs is awful. Cyanogen I was losing 20% an hour with the screen off, the phone untouched. Salvage Mod, I am down to 85% in an hour and a half.
I have read about kernals and how they can help with battery life, speed up performance, etc. What are some that I should look into using and how do I go about applying them? Is there a failsafe if its a bad flash?
Also since Sense feels so slow and bloated (to me at least) what are some other good AOSP ROM's out there? That have a little more to it but is not loaded down with unnecessary tools I will never use.

Personally I run:
rom: CM7 Nightlies
Kernel: Tiamat 4.0.6 [3.3.7 is the GOD of battery life]
Mods: Viper mod, undervolted at 825mv floor and -100mv
CPU: Under clocked at 128 min and 537 max
Many people use my setup now and get great results, so I would recommend it to you.

Doesnt the nightly ROM tend to have more issues or do they run better than the stable builds?
What are the Mods? Viper, and then what does it mean undervolted at 825mv floor and -100mv?
Thanks for the help thus far!

mods = modification type tools
viperMOD is a mod put out by viperboy. it allows you to undervolt your kernel.
less voltage should translate to less battery consumption. take your time and read the post, it may look intimidating but it's rather simple. NOTE: if you lower your voltage too much your EVO will get stuck at the boot screen during the next reboot. do not fear...simply go into recovery and reflash your nightly this will reset your voltages. i'd suggest lowering the voltage in increments of 25 or 50 till it hangs then raise it by 25. run with that for a few days to see how it feels.
you may want to look at the Supercharger script (see signature), its not a battery saving mod, its more for memory management and system responsiveness. again, the OP looks intimidating but a reflash will reset your system. (ie: you will have to rerun both ViperMOD and SuperCharger each time you flash a new nightly)
nightly's may or may not be more stable than the RC. it all depends on what was added the day before. the easiest way to find a good nightly is to scan thru the nightly thread for a nightly that is a day or two old...if it causes issues folks will cry and moan in that thread...once you get a nightly that works well for you i'd suggest you stick with it until the link below indicates a new feature or fix that you need/want.
this page will list the EVO related changes included in the latest nightly
http://cm-nightlies.appspot.com/?device=supersonic
see signature links to viper, super and nightly threads.
have fun.

Salvage is awesome. Extremely light and plays well with V6 Scripts. Try them all out, give them a least a couple of days each.

How long does it take for the battery life to stabilize? Its looking like Salvage is averaging out to about 10% an hour, but I know I could do a whole lot better than that.
Any other Mods, kernals, or ROMs (especially AOSP) you guys would recommend?

After flashing a rom, charge the phone up to 100%, then go into recovery and wipe the battery stats; you'll see the change in roughly 2-3 days, as it has to 'settle' in.

note: there is a difference between a SBC and nonSBC kernel. this has to do with charging the battery. there are some folks that do like/trust SBC and others (myself included) that appreciate SBC. basically, SBC pretty much ensures that if you plug in your phone at night before you sleep when you take it off the charger in the morning you will have 100% battery to work with. Stock (or nonSBC kernels) will charge to 100% then stop charging and drain to 90% then charge to 100% rinse repeat. this means that when you take it off the charger you will have somewhere between 90-100% charge.
also, keep note of which applications are sync'ing and at what interval.
for example: do you need facebook to sync each hour? do you need weather to sync each hour? etc.

Also you might want to try SavagedZen RC4 and/or its kernels. They have built in HAVS (like Vipermod) and on the fly SBC (you can just uncheck and check it off)..

Jakister, do you have a link to that ROM? Reading up on it, it sounds awesome. I followed the main thread and the link to download it is dead
Nevermind, it must have just been down when I tried to DL it.

Try this one: http://mirror.savaged-zen.com/ forgot abt that dead link..happened to me when u try it from "mirror" instead from "download now" link. Works?

That one worked! I have flashed the Tiamat (sp?) kernal and the battery life was great for awhile but then it started to dive again. Also, the GPS could never grab ahold on the Cyogen mod. One of these days I will get it right!
Any other AOSP kernals you guys would recommend me look into? I also have the smartass governor on and have my CPU marked to go from 245-729. Do I need to make that lower? I figured 729 was a good compromise from 998
Any other AOSP Roms you guys would recommend?
I have looked at
Salvage Mod
Savaged Zen
Cyanogen Mod
Are there any other ones worth looking into? I think I need to figure out undervolting or find a better kernal

My Configuration
Savaged-Zen kernels have a new download server which can be found here: http://sz.munkibizness.com/ I personally use MIUI with a Savaged-Zen kernel along with viperMOD and Supercharger V6 for speed and simplicity.

How do Vipermod and Supercharger work exactly? You change the settings for those in the Terminal?

Yes, you change the settings for them in the Terminal. However, for vipermod, I use Terminal Emulator (available free in the Market) and for Supercharger V6 I use Script Manager (available free in Market also) and BusyBox Installer (in Market). For BusyBox Installer, make sure you have 1.18.2 or lower installed from within the app.

[Kernel] [CM9 - RC2 & RC3] honeyx 7up 2.6.35 kernel [for better battery life]

Due to some requests via PM´s I decided to make my kernel finally public, but remember:
This kernel is a personal kernel for my private use, so it´s only containing the tweaks I´m also really using
It´s the older 2.6.35 kernel basing on latest 2.6.35 sources from Arco, so only use it with Arcos CM9 RC2 or RC3 or a custom ROM with 2.6.35 kernel
This kernel is not filled with a lot of governors and schedulers, but only the ones I´m also personally using.
I have made this kernel because non of the custom kernels worked stable for me in the past, even at stock voltages. With this kernel I´m able to run at extreme Undervolting rock solid.
So this kernel was created with stability and battery life in mind. Each modification was tested separately, so everytime I added a tweak or a new feature, I tested the new kernel for a couple of days before adding the next one.
So why I decided to tweak this older kernel rather than going with 3.x kernel?
- Because this kernel is giving me a much better battery life than the 3.x kernel, is running rock solid and also because I don´t really need the new features added into 3.x kernel.
So what it has included:
- UV and OC options
- lowered WiFi voltage
- lowered lcd voltage
- slightly lowered standby / deepsleep voltage
- Battery life extender
- Fixed 100% battery notification after charger unplug
- 377MB RAM
- NO-OP scheduler as default scheduler
- Lulzactive governor as default governor
- tweaked Lulzactive for battery life and smoothness
- added 518, 633 and 902 MHz (new)
- screen off frequency set to 518 MHz max.(new)
- some more voltage tweaks
- no other compilation tweaks just to make the list longer
With this kernel and a new battery my SGW can last up to 7 days in standby. This is without WiFi and Mobile Data. With the stock kernel I got 3-5 days. It´s also working absolutely stable and smooth for me without any issues.
So if you run into some issues that are/were also discussed i the CM9 Bug report thread, don´t blame me for them.
other suggestions:
- enable KSM
- enable 16bit Dithering
- disable CPU rendering
- greenify your apps
If you follow these suggestions, your ROM should run absolutely smooth without the need for other tweaks.
To use Battery Life eXtender:
Use RootExplorer and go to: '/sys/class/misc/batterylifeextender'. Change the value in 'charging_limit' for example to 90 (default 100). This will set a limit for the capacity to which the battery will be charged. So in this example the battery will be charged to 90%.
----------------------------------------------------
After flashing the kernel whipe your cache and dalvik cache and fix permissions.
Just as a note. Should you encounter the white screen bug in some apps, this is because you whiped the cache in CWM Recovery after flashing the kernel. To fix this go into settings -> apps and delete data and cache of those specific apps.
Credits are going to:
- Arco (for his great work and sources)
- educk (for helping me doing the first steps)
- Christopher83 (for his great commits)
- ivendor (for his tweaks)
- Ezekeel (for Battery Life eXtender)
----------- 18.08.2013 -----------
- added frequencies
- incrased RAM
- lowered screen off frequency in Lulzactive
- some voltage finetunning

nicely done

I have tested this before with rc2 and I have to say battery life was very significantly longer compared to hurtsky 2.5 + QAsR v2.3. However, the white screen issue persisted in 2 of the apps I used the most, namely boat browser and Gmail so I have opted out again. But if you guys don't care about white screen, do give this kernel a try

Yeah, kernel 2.6 is always better battery life... i recomended it
- screen off frequency set to 768 MHz

What mean of that ?
is we get trun off the screen it auto lock on 768Mhz ? it's not deepsleep any way CMIIW

This is the max frequency the clock might rise to if the screen is off but for example an app or a service awakes the phone from deepsleep. So it will not drain so much the battery if the phone gets awake for some reason and if you undervolt your cpu, you can reduce the consumption for such a case even more.
This is preset in the Lulzactive governor, which Christopher83 fixed to make this working, so it´s only related to this governor, which is also my default governor.

So when in screenoff the phone only maximum can use CPU clock at 768Mhz
Yeah i get it. .thx for explain it

I think arco might be able to help you fix the white screen. Long back skull kernel experienced the same and acro helped him to fix it.

Uhm, well I´m not sure this is exactly the same because Keff (Woohooo..) is modding the 3.x kernel for CM10. But thanks for the suggestion. I will aks Keff first to not to bother Arco in the first place. It will be for sure interesting what caused it for him.
Just to clarify some things about the white screen bug. The one I described in my first post is not the real white screen bug, but only what happens to some apps after whiping the cache in CWM Recovery. This can easily be fixed like described above and will not bother you anymore.
The real white screen bug came all of the sudden (without whiping anything before). So for example you opened facebook, everything was fine, but a few minutes later by relaunching facebook you got a white screen. The procedure to get rid of this was the same as I already mentioned but with the difference it happened again after a while.
So well I have had this issue with facebook too in the past, but it´s gone and now even not happening after whiping the cache in CWM Recovery. It´s not gone because I updated the rom (still using RC2), but because facebook updated their app.
Edit:
I already found what you was talking about. It´s called the white noise issue where you get a white screen by turning the screen on, so it´s not the same.

Mind you: This is battery saving rom. It is meant to have low game performance. It MUST have a lower gaming performance than those v3.0 kernels. If you want gaming, this is not for you.

Yes, this is a battery saving kernel, but why should it have low gaming performance? Just because it´s optimized for low consumption in standby and because you can undervolt it? It´s like you were comparing an older Pentium4 against an Intel Atom CPU and saying the Atom must be faster because its newer. Or by comparing a Atom against a 286 CPU and saying the 286 will be faster than the Atom because the Atom is more battery friendly.
Sure, it´s not optimized to get the highest scores in benchmarks, but the games I´m playing once in a while are running totally smooth.
The newer releases of CM9 might be of course faster in games, but not just because of the 3.x kernel, but also because Arcos ocessionaly is updating the GPU drivers.

Thank you for correcting my ignorance. :laugh: Maybe I'll give the kernel a try and tell more about that

Honeyx, I hope you continue to develop and share this kernel in the future because I decided to start everything over from scratch because of your work here. I love this kernel. I get so much better battery life now. If you would ever consider adding Lionheart in the future, I would be very grateful. Is there any way to add Row or does it require kernel 3? Thanks again!

Honeyx, I hope you continue to develop and share this kernel in the future because I decided to start everything over from scratch because of your work here. I love this kernel. I get so much better battery life now. If you would ever consider adding Lionheart in the future, I would be very grateful. Is there any way to add Row or does it require kernel 3? Thanks again!

I may add some tweaks in the future, but this may take a while till I have some spare time to test them. About adding other governors...well I tested a lot of them but finally decided to use Lulzactive because it was the most battery friendly governor in the one hand and because there is also the Lulzactive app you can use to tweak it to your needs. So for example tweak it that way it behaves like for example Lionheart. I also tested the ROW scheduler but it wasn´t as stable as I presupposed to be. So the best compromise between stability and performance was to use the noop scheduler. It´s nearly as fast as the row but way more stable.

LoL. I´m quite sure with extreme undervolting you can still save some battery juice even while playing action games on this device. Beside this it´s not the CPU or GPU that consumes most, but the display and its backlight LED´s.

it is for battery saving but for me its not good to play with games cuz playing for like 40-60 minutes consume 60% battery ? lol
thats quite alot and might burnt up my battery life.

So did you thought it will consume just as much as being in deepsleep????????? The kernel is tweaked to consume less in deepsleep and in daily use but not to consume less in games. Beside this it´s not the CPU nor the GPU that consumes most, but the backlight LEDs in your screen. So even by undervolting and underclocking it will still drain a lot if playing games.
There is no and will not be a magical Kernel that is using witchcraft to reduce the consumption of the LEDs, exept someone compiles you a kernel which turns out the LEDs completely, if you can with a complete dark screen.

Im not expecting anything from ur kernel, im glad that u shared ur kernel taht could last longer than arco's stock kernel.
I was just giving up my comments about ur kernel that i have used for 2 months , Not complaining and whining lol.
I am sorry and thanks for sharing ur kernel , keep it up. :fingers-crossed:

[Kernel] [CM9 final] honeyx 7up 3.0.x kernel [Silky Smooth & Battery] 02.09.2013

ZOHAN makes your hair...emmm Kernel silky smooth .
Well, since it became popular to add something like " for better battery life" I´m renaming my Kernel into Silky Smooth now
There are 2 versions now. First one is the pure kernel and the secound one with Turbo Boost included. (Credits are going to delta-roh)
Orginal thread: http://forum.xda-developers.com/showthread.php?p=37905307
SGW discussion thread: http://forum.xda-developers.com/showthread.php?t=2400120
Created with stability and battery life in mind. Each modification was tested separately, so everytime I added a tweak or a new feature, I tested the new kernel for a couple of days before adding the next one.
So what it has included:
- UV and OC options
- lowered WiFi voltage
- lowered LCD voltage
- slightly lowered standby / deepsleep voltage
- Battery life eXtender
- Fixed 100% battery notification after charger unplug
- 378MB RAM
- ROW scheduler as default scheduler
- Lulzactive Governor as default governor
- tweaked Lulzactive for battery life and smoothness
- added new frequency - 518MHz
- added new frequency - 633MHz
- added new frequency - 902MHz
- Screen Off frequency set to 518 MHz max. in Lulcactive Governor
- Dynamic Read-Ahead
- Dynamic Dirty Page Writeback
- CK3 tweaks (Credits to Con Kolivas) - adapted by Christopher, hurtsky and me
- LowMemoryKiller management of not killable processes - credits to christopher
- with and without Turbo Boost Mod
- no other compilation tweaks just to make the list longer
I didn´t test this kernel for how long it can last in StandBy / DeepSleep max., just for stability, how well the tweaks are working and how well the consumption is dropping in DeepSleep, but since the results are very similar to the ones by using 2.6 kernel, they also should be quite similar in this kernel. However with the new added 518MHz it will consume less in Screen Off Mode if the phone is active. So for example while making calls.
The max. Screen Off frequency is the maximum frequency your device can clock to while the screen is turned off. It´s a kind of limitation to lower the consumption.
other suggestions:
- enable KSM
- enable 16bit transparency
- disable CPU rendering
- greenify your apps
If you follow these suggestions, your ROM should run absolutely smooth without the need for other tweaks.
To use Battery Life eXtender:
Use RootExplorer and go to: '/sys/class/misc/batterylifeextender'. Change the value in 'charging_limit' for example to 90 (default 100). This will set a limit for the capacity to which the battery will be charged. So in this example the battery will be charged to 90%.
----------------------------------------------------
After flashing the kernel whipe your cache and dalvik cache and fix permissions.

Just in case you are getting random reboots with this kernel this is because your device doesn´t like the lowered voltages for DeepSleep /Standby. In this case use the kernel below insteed. It´s the same kernel but just without this tweak.

This is really heavy usage, so I´m not sure it will make a lot of difference even if you are undervolting. Most of time your screen is on and so the phone kept awake but it´s the backlight that is draining most.
It´s just there is no tweak for the backlight LEDs to make them consume less exept reducing the brightness, so may I ask if you feel any difference even under such a heavy usage?
I doubt that as the kernel is tweaked for Deepsleep / Standby but will of course consume as much as other kernels under full load.

Ok., let me say that I have use another kernel before with same time testing (about 3 hours and 30 minutes) and my battery drain so fast.
Honestly this kernel is good for battery saver because I have problem with my battery health..

this kernel compatible with cm9 rc2 or rc 3?
or use the EOL version one ?

It´s kernel 3.0.x so more likely for the EOL and as the title says it´s for CM9 final.

how much memory on this kernel?

For me it´s working well and I didn´t do any changes to it, so everything is like in the stock 3.0.82 kernel regarding this. It´s just you have to wait up to 15 minutes after activating GPS the first time after changing kernels to get a GPS fix.
I of course tested GPS before launching this kernel. It took me a while to get the first GPS fix but after this it´s now fixing immediately. However If you are using Greenify and are hybernating your Google Services, this could be the reason for not being able to get a fix.
Btw, this has been already discussed in the CM9 bug report thread. There are also some solutions to get it working.
http://forum.xda-developers.com/showthread.php?t=1598056&highlight=gps&page=299
But I also suggest to not to hybernate Google Services in Greenify as some apps require it to get a GPS fix. Once the Google Services got greenyfied those apps can´t get a GPS fix, even if you restart Google Services. So in this case remove Google Services from the list in Greenify and restart your device.

Personally I´m using these:
Code:
Freq. mV
245760 775
368640 825
518400 900
768000 950
806400 975
1024000 1025
1113600 1050
1209600 1075
1305600 1100
1401600 1125
1516800 1175
1612800 1225
1708800 1275
1804800 1325
It will also run stable for me by reducing each by -25mV. Just added 25mV to each for more stability.

Thanks for the great kernel, I personally haven't noticed much of a difference on standby with wifi on, but there is quite a difference when you're using the device, thanks again! :good:

Thanks for the feedback. Well about WiFi this is another story. While testing the consumption with WiFi on I honestly couldn´t see any difference between running WiFi at stock voltage or by undervolting it the way all the kernel modders are doing it.
It looked to me like this tweak isn´t lowering the consumption like it expected to be. Therefore I applied some more tweaks you can´t find in the Commits to lower the consumption while WiFi is enabled. The difference is not huge, but now it indeed consumes a little bit less. Beside this my tweak is a dynamic one and depending on the signal strenght.

this kernel is really impress me,.fast and smooth and really better battery life especially the 3.0.x kernel.
i dunno if this is just me but i have to report this,.
sometimes my phone just turn off by itself when i'm using it, both 7up kernel are the same.
is there anyways to fix this?

Hm well I´m not sure. Would need to know your exact setup to better estimate this. Did you install both roms the prstine way? Are you using any other tweaks, mods, themes or scripts?
I´m using Arcos stock CM9. There I´m using Apex launcher and the only mods I did is disabling CPU rendering and replacing the SMS/MMS app with the modded one. Additionally I replaced the Clock App with one that offers a digital Clock widget and swapped the SDCards, but that´s all about it.
It´s of course possible the tweaks in the kernel are somehow interacting with other tweaks, mods, themes or scripts. That´s why i cherrypicked all the tweaks I added into this kernel and skipped the ones that were causing troubles when combined together.

pristined as always,.
no mods, no themes, no tweaks and no scripts
only cm9 stock + 7up.
hmm..on 3.0.x got 2x turn off by itself. 1. while using Path, 2. while using Line..
i dont remember when my phone turned off when using 2.6..

Ok. I just forgot to ask if you are undervolting or orverclocking your device. However I will build you a test kernel without the slightly lowered voltages for Deepsleep and Standby because this is what comes into my mind what could cause you the random reboots. Kernel 2.6 has less tweaks than other kernels are having exept this one. In 3.0.82 kernel I tweaked them even a bit more. So maybe your device doesn´t like this.
I will PM you this test Kernel when I´m done, so hopefully we can narrow down this issue you are hiving.
