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.

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.

[Q] Should i change my ROM?

Im using PCF V5 with Zeices Kernal, so far been the best ROM that i have tried, no complains, just one, i cant get more than 97 % of battery, just stays at 97%, i already did battery calibration and removed the battery stat from recovery but still the same, not an issue since batter last a full day with constant use, i set my CPU to 245/787 MHz using smartassV2 Governor, i get 1282 on quadrant. i been seeing post about SwiftDroid SDSL vPre-Final being better than PCF v5, is this true? should i change? or what other ROM would you recommend?

to me yes sdsl is better the graphics has a huge boost (a big plus if u game alot)

Many people talk about saving battery BUT..

But, anyone knows a good rom or kernel that needs more battery but with better performance? like better phone reception and sinal, good power for wifi and Gps? i don´t care if battery go to 0 in few hours but i need strong sinal and good reception, now i´m using slim 3.7, original kernel and modem JVU

No ROM will magically boost the power of your phone's hardware, but I think devil kernel can work for you, ie using powerful wifi mode, and it's also a great kernel for overclocking.
Using GT-I9000 my sent Tapatalk 2 from.

There are few ways of achieving better signal and better stability with greater performance. As adytum said, try another kernel, Devil or Glitch, they have good stability and variation of options. Next, change modem to see if u find any better than JVU. Last is to carefully use LiveOC and OC/UV. I recommend using CM9 with Devil or IcyGlitch (I prefer Icy but Devil offers more RAM) and with I/O scheduler set to deadline performance or GlitchOnDemand if IcyGlitch kernel is used. Optimal is 108% LiveOC and OC set to 1200 in NSTools or performance setings, u should get a bit more than 1300MHz in overall. With that config u can get about 10h of fun. Good luck.

I think it's not a rom issue but a kernel and modem thing. I have good results with semaphore kernel and jw4 modem, but each phone it's a different world, I recommend you to try different modems and see which works better for you

[GUIDE] N7 2013 'Best' Kernel (Performance & Battery Tests)

After doing this guide for the OG Nexus 7, I picked up a 2013 version. I'm loving it but my battery life has been a bit all over the place.
I decided to look into kernels and I have come up with the same guide/tests/results that I did on the OG Nexus 7
I was intrigued and decided to work this out for myself and share it with the rest of the community.
This is not meant to hurt the makers of these kernels.
But FIRST, it is not a fact that there is a 'best' kernel. 'Best' is an opinion and everyone has a different opinion.
I personally believe there is no 'bad' kernel and none of these kernels I have tested perform badly or lag heaps.
People still like to push their N7's as hard as they can though.
Please take my results with a grain of salt. This is hardly scientific and results will vary heavily. This is just my results.
The Main 2 Features people look for in a kernel are:
Performance & Battery Life
Some people prefer performance over Battery, or vice versa, or an all-round kernel.

Very interesting...

How did you achieve to make nexus 7 boot on 2.2gh on elemental kernel? Mine is crashing all the time in this frequency...

Your AnTuTu Scores seem to be totally weird. With Only 1.8GHz FUAX Kernel reaches over 25.000. I think mabe some kernel will work better on CM ROMs than on Paranoid, so comparing there performance is pretty difficult. When i comes to battery it's really confusing that with some kernels and highly overclocked cpu the battery lasts almost as long as without overclocking.
But thanks for sharing your results. I had already appreciated your work over at old Nexus 7 Thread.

I too have my nexus 7 running the 2.2 frequency. It does not crash at all. In fact it literally makes my tablet a super beast. That said though, not all processors are equal... They may all have the same specs yet they are not all equal in the frequencies that they can withstand..it is literally luck the draw...I'm pretty happy though, I always end up with the device that can handle the higher frequencies...I lucked out this time....

The score is similar to what I got on stock JSS15R. Only a few custom aosp and cm based roms have much higher scores at the moment. Reason still remains unknown.

can you tell us what options you chose when installing Elemental?

Can you please say which governors are default for each one?

Defaults besides the overclocking

Funny thing: I switched from Galaxy Note forums to the Nexus corner and just saw this thread.
In the Note forum best Rom/Kernel threads are immediately closed by the Mods because they are against XDA rules/policy.
"Best" is only a very personal view - and all these tests are without any value (for many reasons).

Thanks, very informational

voted eX v1.4 im on ! u can OC and it still better batterylife then stock! also good antutu score, 21680 i got

I think the big difference between this and other "best" threads is this actually has some reasonable information. Other threads that get shut down are mainly "what do you THINK is the best..." and don't have any actual data to go with the opinions. Are these test here definitive? No, but still useful. OP, t:good:hank you for doing this.

Nice to see a thread like this. They are usually not allowed but are extremely helpful for comparing.
Comparing didn't have to mean which is better. It could just be a matter of what someone is looking for.

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.
