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.

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.
Hello, first of all this is my first post and thread. I have read the rules and searched for a similar thread. I am not stupid and I know how forums work. Now my question is: Which is the most performant kernel for the MT4G?
Know to be more specific, I am looking for a kernel which a very high OC and UV rate. I want something that can easily manage clock speed when it needs it the most. I am interested in genereal boosts of speed, higher I/O managing speeds, better gaming experiences and a longer battery life. I know that the kernel doesnt do all of that but it has a major impact those aspects. I am running CM7 nightly 144. Im hesitating between Faux123 Cm7/AOSP 2.6.35.13 kernel (http://forum.xda-developers.com/showthread.php?t=1113697) and thederekjay 2.6.35.13::demonSPEED INSANITY kernel (http://forum.xda-developers.com/showthread.php?t=1113554). I appreciate anykind of constructive feed back
I personally use demonspeed-insanity. It'll clock up to 1.8 atm. Couple that with the SMARTASS governor and you get a pretty decent balance of battery life to performance.
can't go wrong with either kernel, i've used both and their both outstanding in performance and battery life.
Sent from my HTC Glacier using XDA Premium App
Thanks for the feedback guys . I'll probably try both of them. I'll post some quadrant benchmarks and battery life results.
Faux 123 1.0.7 is the best IMO, great uv and quadrant scores, got 2600+ on stock and battery life is great.
I have used both kernels and got great battery life from each one. I prefer Faux's kernel for AOSP roms, and thederekjay's kernel for MIUI roms. Faux updated his kernel to OC @ 2.03ghz and its blazing fast
Faux's all day!!!!
He has put in the most work and has the best performance by a wide margin.
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.

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
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.
