[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.

Best SetCPU Config for Desire

Hello
Does anybody use set cpu with HTC Desire ?
I would like to know wich settings work the best for you. I am trying to get the best compromise between battery life and performance.
Thanks

128MHz - 998MHz ondemand. I get more than enough life out of it. I found that if your using AOSP and not really doing much on it like just texting or calling people, capping the max to about 600MHz or 500MHz if you want, works a dream and you get even longer out of it.

Smartass is better or worse ?

I do not see any real difference between smartass and interactive in term of battery live and performance.
On demand seems to drain slightly faster than smartass.
I set my Desire to 384-1136 with interactive govenor.
I charge it once i a day each time before I go to bed anyways (sleeping time usually23.00 - 05.00), so further battery saving is not necessary to me
Edit...my normal usages are:
Syncs (no auto sync by opening):
Friendstream 4 hrs
News 4 hrs
Weather 6 Hrs
push Yahoomail
push Googlemail
push Whatsapp
push EBuddy
Active background :
Lookout antivirus
No app killer used
Phone calls : about 1-2 hrs each day
Music listening mit DSP add-on : 4 hours
Fruit ninja (man! this is addictive!) : 1 hrs
Browsing (Dolphin HD + Android market) : 2 hrs
welll....every time I charge my battery it is about 15-25% left till out of juice...if I use my phone more than those, I have to charge it earlier (more than once a day)

245 - 985 MHz Conservative give mere 36 hours power and running smooth.

For me the battery has never lasted more than a day... Even on my un-rooted one...

BTW: Battery live depends on many things
1. Your ROM and kernel
2. Your runnning application, syncs, etc.
3. your usage and settings such as cpu freq, display brightnes, airplane mode, etc.
4. Received signal quality.
5. The condition of the battery...is it top fit for example?
It is difficult to measure the battery live.
@atuladhikari : battery live has nothing to do with rooting..

I don't like using any of the other governors since I get lag. I hate lag. OnDemand gets rid of the lag for me. I've had it before where I was using smartass and it took ~30 seconds for my screen to turn back on from idle. I wasn't too impressed.

setcpu
thanks meaple for your advice
i think that set cpu is fine on "ondemand" for some roms and for others roms no
set cpu is included on oxygen settings and running well

Cool, I need to download Setcpu

128-998 ondemand
screen off 128-384 ondemand
in call 128-384 ondemand
I get very good battery and performance with theses settings.

Which app do you guys recommend? Tried overclock widget doesn't seem to be working.
Am on Insertcoin stock GB rom.

DidI do that?....I did.... LOL.

I used to use set cpu
set a profile like
Smartass
on charge - 1113mhz
80% - 100% - 998mhz
59% - 79% - 600mhz
35% - 58% - 500mhz
Screen Off - 300mhz
Priority was higher for lower battery %
BUT I stopped using it because of the little bugs, like when it changes to 384mhz for no reason after unlocking screen
It also affects the standard script with the rom you install, so you can never uninstall it properlu, you have to do a full wipe install and never install it, until I did that my phone was always a little laggy
I prefer my phone without it Each to their own

@shankly1985 - you didn't noticed wakeup lag with 128 MHz?
I must use 245 - x MHz to properly and fast unlock my phone.

Best Setcpu config for Desire is - no Setcpu at all.

I couldn't agree more with you. Experienced all of the above so no go.

245-1033mHZ with smartass give me two day out of my desire loaded with insercoin 1.0.9 with v06 kernel !
I am mostly sending Text message and some calls.

Not at all mate, I get zero lag on my phone. when I check the info on the setcpu app and time in state 128 is at 85% so my phone is using very little cpu.

KISS-Kernel

excuse me; have question about this kernel; i couldn't post in the original thread;
by setting the min clock speed to 768MHZ & the max to 1407MHZ, How much voltage does it spend? by setting the min to 245MHZ & max to 1024MHZ how much? i overclocked to 1407MHZ , i saw more smoothness and speed; but i felt that its consuming more power!
is overclocking harmful to CPU? ( always overclocking )
Rom: MY One V RC4.0 FX

Kernel: Latest Kiss Kernel

Hi
Political correct answer:
Of course OC "can" harm your device - like all OC´ing
Realistic answer:
Most One V devices can handle OCing up to 1.5 without problems
but since this may be specific to chip manifacturing there is no
guarantee that it is. Therefore before using any OC you should
test it very carefully.
And also - Of course running the chip at higher frequencies needs
more power. Simply physics .)
In "normal" daily use the difference is not big because the cpu will
not run at high frequencies most of the time. If you do things
like "heavy" gaming this is of course forcing the cpu to run faster.
To reduce the "effect" a little bit there is a kernel feature called
Undervolting (UV) with that you can reduce the voltage for
specific frequencies. Like OC this is device specific. So some
devices can run stable with more reduced voltage then others
BTW: why to you set the min frequency to 768?
This will limit that the frequency cannot go lower then that if the
device is idle. Running at 245 needs of course less power then 768
max

Thanks for the nice info, well, i heard that some users said that the best frequency for " My One V" rom:
Minimum: 768MHZ
MAX: 1407
I'm using "Set CPU" to OC
So setting the min frequency to 245MHZ will save more power, right?

Yes - especially for the time before the device can go into
"deep sleep" when beeing idle.
The only "disadvantage" is that depending on the govener that you use
there might be a small lag before the frequency scales up
Actually it depends if you notice it at all
If you use govener ondemand it should be no problem
if you use e.g. smartassV2 you might consider thinking about
using some tunables that will reduce that behaviour.
max

Thanks, yeah, i meant for normal activities, like checking Facebook,mail, watching movies ... So ondemand mode would be better

What is your recommend governor to integrate with your Titanium-KISS kernel and what is your favourite I/O Scheduler tweaks, for daily use & heavy gaming?
I'm using smartassV2 & i set my I/O Scheduler to deadline until now, because it's peoples favourite
Should i change it to ondemmand to gain a better performance?

I set my friend wonder with 368 i believe in min frequency and max 1ghz, and it is still smooth with smartassv2 / lulzactive / brazilianwax. And it is battery friendly either capping the max to 1ghz only. You should try that and see the changes. Although the battery is not drastically save but it is slightly different from capping the max to 1.4. It all depends on the kernel you're using though. Whose kernel you use?
And for your song problem on screen off it is caused by your min frequency it is too low for running app in 192, try to raise the min frequency to 245 / 368. For my friend phone 368 is the most stable for what your facing.

[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

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!

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
