What Kernel are you guys using on the lastest CM7?

How many .35 kernels are available? I'm only aware of Umaro's and the stock CM kernel. I'm trying to achieve better battery life, so what kernel are you guys using?
So far, using Umaro's, I'm getting regular battery life, nothing special. Haven't tried the stock CM kernel.
Are they any other undervolted kernels available?

There aren't any others so far. Umaro's kernel is really good for battery life, however it's not up to date with the latest kanged nightly from yesterday.

Ahh, I see. Thanks for the info.
What cpu settings are you running?

Right now I'm using a kanged nightly with the "stock" cpu settings of 245MHz min and 1024MHz max, but with the interactive governor. With Umaro's kernel I had at 245 min, 1017 max and the Smartass governor. The smartass is pretty good on battery.

u made all the right moves all i would do is dim screen and keep runnimg apps low.
pimped out g2

btw pyromod 2.0 345 ghz min 1405ghz max on smartass. i fully charge bout 1 a day
pimped out g2

Pershoot released his kernel the other day pretty nice and smooth

Alright I'm sleepy so this will be in rambling form but...
I've tried Umaro's and I'm not sure if it was the undervolting (which I haven't looked into tweaking) but my phone kept stuttering no matter which governor I used. I was using Htcclay's Super CM7 1.8 with cpu set to 245/1113
I also used the stock kernel that's been on CM7 with no problems and average to good battery life (10-15 hours of active use: texting, browsing, few calls, and playing the occasional game)
Most recently I've used Pershoots which I had heard worked great. I myself love it. Almost same battery life as stock kernel but everything felt just a little bit smoother performance wise.
Here's a link to Pershoot's thread:http://forum.xda-developers.com/showthread.php?t=847672

The stock cm kernel in my opinion is finally good enough that it doesn't need changed. I have always flashed pershoots and occassionally others, but it truly does not need supplemented IMHO.

I'm using savaged zen, and I get around two days of battery on a charge, with normal use.

Using Pershoots latest kernel, have nothing but good things to say about his kernels. Always my go to kernel.

You're running that on Vision? I can't seem to find it for our device.

Stock CM7 kernel here. I run 245/806 Interactive with automatic brightness. I've found that when wifi is on, keeping the cell radio @ 2G only works wonders. Wifi is set to sleep on screen off, but not when plugged in. 1 day 7 hours on this charge so far with 23% left. I would consider my use light to moderate.

I'm wondering where can I download the Umaro's kernel. I check out his github (https://github.com/umaro/htc-kernel-msm7x30) only to find out that the source is available.

Please share your voltage and governor

Please share
1. your favorite governor (do you use any different governor on different profiles?)
2. your voltage parameters
3. Your benchmark using quadrant
Thanks

No one wants to play?

Maybe like me, they have no idea what you are talking about
What is a governor?
What voltage do you mean?
My quadrant score is 3900 ish

Thanks for the reply, I don't think I'm good enough to explain but, in a nutshell,
A governor is a a piece of code in the kernel that decides on the cpu speed. each kernel has multiple governors
voltage is where you can decide what voltage is delivered to your cpu at certain frequency. undervoltage will usually help you save battery. we have to pay attention not to go too low or it phone will freeze
download setcpu it will all become clearer

I will give this another bump before letting it die

Even I would be intrested in sharing this
currently I am using CF root with ondemand and its working all good

FM kernel with interactive. I find my phone snappier with this governor. I liked it the most with smartassv2 on Abysssomething (don't remember now) kernel, but too many teething problems with this one, had to revert to FM. I'll give it another shot soon though.

Do you use any additional profiles with Interactive?

Nope, I like the way it is.

Have you tried InteractiveX? Or, better yet, know the differences between the two? I am currently using smartassv2, FM kernel and have no complaints but would be interested if there was something a bit snappier when opening an app (I still get a bit of lag if I quickly select an app after unlocking the phone).

Yes, I've tried InteractiveX and OndemandX - they're both absolute rubbish (at least from my point of view). Both responsiveness and benchmark results were dismal (2800-3300 quadrant advanced). These are governors for anally retentive battery life lovers. Nothing wrong with that itself but beats the purpose when buying state of the art top shelf performance smartphone IMO.

Good to know. I appreciate the advice. Does that mean you also tried smartassv2 with the FM kernel? Any discernible difference between that and interactive, if you have? And sorry for all the questions but it saves me the trouble of trying them!

I just flashed the 1.3 FM a moment ago. Now running 100-1704 smartassv2, haven't played with voltages yet. Responsiveness in terms of screen scolling, lags & stutters seems better than 200-1400 interactive. Performance in Quadrant Advanced and Nenamark2 seems a tiny bit worse (but I don't really care about that, I use benchmarks only to roughly estimate, smoothness is what I'm after). I can't give you direct sources because I don't remember, but having spent several hours digging last weekend I concluded that for people who put performance slighly over battery life governors to be considered are interactive, smartass(v2), savagedzed and performance. Funny enough - I'm getting consistently worse benchmarks on performance governor on all kernels. I wonder why?

Thanks again. I will play around with some of the governors and settings to find the right fit. I think I will try savagedzen next but I am pretty happy with smartassv2 and may just stick with it.

Smartassv2 and vr. After reading a bit about it they seem to be the best for performance and balanced battery life.

i share with you my SetCPU config, voltage ...
it's very stable for me. It's not performance oriented but battery friendly.
what you think ?
EDIT : I use AbyssNote Kernel 1.2

I'm getting nice results here on FM Kernel 1.3. 1704mHz (1375mV) - 100mHz (775mV), lulzactive governor. 5000-5872 in Quadrant advanced, 32-35 in Nenamark2. Battery life good with low to med usage, poor when playing games, running satnav etc. - hardly a surprise We'll see about stability but so far so good.

This thread is finally picking off ! thank you all
I am currently on FM 1.3 and preferring lulzactive
I don't use any over clocking I guess I don't dare. is it safe?
I think i'm pretty aggressive with under voltage i'm running 1175mv at 1400mhz and 775mv at 200mhz. For some reason my phone freezes any time I use the 100mhz no matter the voltage .
Can you share the whole voltage for a comparison ?
with all this I can hardly get a full day of use with my battery but I guess I'm a pretty heavy on usage. no gaming or anything extensive but wifi-browsing-emails-3g-bluetooth all day

I read on some other kernel thread that Samsung's implementation of the 100mhz step is incomplete/buggy. That's probably why it doesn't work properly.

[Q] what is yours favorite kernel (i9505) and why.

Mine favorite kernel is chronickernel i really recommend this kernel because it can oc the gpu and the cpu. But besides that the performance and battery life are just awesome

I second this. Chronic Kernel is by far my favorite kernel. The only kernel I've used that has gotten 10 hours 45 minutes screen-on time with the Stock battery no joke. And performance is amazing. 29k on Antutu is pretty awesome if you ask me

TW kernel

Can someone recommend good kernel, for tw rom, good performance, also battery and with no sods with best stability, im new here and saw many kernels with oc 2.8 GHz and undervolting, best battery and etc, so tell me your oppinion

It is a hard question but the answer is pretty simple. What is good for my phone does not necessary good for yours. Need to try it yourself.
And for overclock kernel don't use overclock setting all the day.Higher clock means higher battery usage.

It depends on what u actually need. OC wouldn't be very stable for example. If u don't want a lot of customization and a stable kernel try lean kernel if you like more features try n3. They are actually all pretty good I tried every kernel and haven't had issues. At the end of the day u will have to look yourself what fits u and your phone best. If you need some info about kernels search for kernel explanation. Got help myself not 2 long ago

Reccomend me a kernel

Hey guys.
Looking for a good kernel for my G2(info in sig) ... Looking for a good overclocking kernel, What do you use?
Any recommendations?

Dorimanx allows you to overclock to 2.8 ghz but what are you gonna use that for? The phone gets extremely hot in very short time. What is it that 2.8 ghz can do and 2.26 ghz can't?
Sent from my LG-D802 using XDA Premium 4 mobile app

Dorimanx is very good if you want to overclock it and keeping battery drain at good level.
Best for me is from bruce.Is absolutely amazing and very snappy...

Thanks guys, Is Dorimanx good for everyday usage too?(without overclocking)

iam using dorimanx 5.8 for 2 days now and its stable until now. no issues at all.
but there is one thing to know about this kernel. it offers alot of options via stweaks but its recommend to use the profile settings that are comming with the rom. they are most stable.

I've used Dorimanx for months now , but switched to Bruce2728 kernel ,and i stay with it.
Very fast , smooth , no lags and very good battery life.

I would recommend bruce's kernel that can be found here.
Fast and reliable, good battery life.

Can't beat dorimanx for jb or kitkat. He's a very hard working guy. He never stops improving things.

Simple Kernel v6 overclocks to 2.5GHz. Simple means only Interactive governor included. Works well. 1%/3hr standby. Testing Vellamo bruce2728's kernel rules in multithreading even without overclocking.
