[Q] Best kernel for CM6?

After realizing that I made a mistake by ditching my EVO for the Epic; I returned to the EVO and installed CM6. What a difference! Everything is great so far except for battery life (even using profiles on setCPU) so I was wondering what kernel would provide speed, reliability and battery savings. I'm currently running CM6 kernel and I'm getting around 1250 on quadrant (around the same results of the nexus one with froyo) so I'm happy with the speed so far but I would love some more battery life (I'm getting less than 8 hours with moderate use).
Thanks

What I learn is try a kernel for a day or two. Try another.. you will find one. Not saying do this but this is what I'm doing. Just like finding a rom.. always come back to cm6

Geez, my bad. For some reason I thought I was in the general section.
Can a mod move this thread to the general section? Thanks

Before this gets moved.. all hardware is different. On paper its the same, but what we have learned is that phones respond differently to the software thrown at them. As others suggested, try them out. Snap as well as Kings are excellent kernels. Just find there threads and I can't stress enough to read the op. Most of the questions you have can be found there, as it can be a little cumbersome with all the different versions for some. But yeah, make sure to give it a run for a few days before you decide its not working for you. Your phone needs to get used to it, so basing it off a charge after a few cycles is always a good idea.

Run Snap v7.5 for an increase in speed and battery life.

King's Kernel all the way, and I've tried all the damn Snap kernels.
Mostly, you should be managing your wifi/3g/screen off cpu settings.

I've been using King's #1 kernel after trying (and having issues with) a myriad of Snap kernels. I really like King's and am waiting for #2.

SetCPU profiles?

Hello all... I'm new to Setcpu and have been able figure out how to OC and UV while still keeping everything relatively stable. As of now I'm experimenting with making profiles, I was wondering if someone could post a screen shoot of their profiles and pass on any advice. I am running TNZ Blend 2.6.2 with the Hitman kernel. Here's a screen shot of what I have so far.

The only thing I would comment on is your "screen off" there is no reason for it to be scaling/jumping from 800-1200 "ondemand" while the phone is not being used or the screen is off in general, just have 800 low and high or have 800 as your high and set it to "performance" so that there is no polling being done and it will set itself to the high value which would still be 800 anyway.
You might have a reason for that setting, just trying to save you a little bit more of battery juice.

Definitely bring down that screen off! I have mine set to 200-500 ondemand. I'm sure it'll save you a lot of battery. Also the battery 100% is kinda pointless because that's what the main profile is for. And expect your phone to get extremely hot if you use it while charging since you have it overclocked. I did that same mistake now I keep it at 200-800 to avoid the over heating.

Just a recommendation...you should give tegrak a go. I find it to be much more beneficial than setcpu...

Why scale cpu depending on the battery level? I prefer scaling CPU on my phone by the temperature. 1.6Ghz normal usage and then gradually scale it down if it gets too hot. I bought this phone for its performance, not battery life, which actually is pretty amazing for such powerful device.

be careful with Tegrak, as it doesn't work with some of the non stock kernels, and will freeze your phone for sure..

Pretty good. You don't need the battery>100% profile. Adjust that from the main page.

Yikes! I wasn't aware of that. Guess I'll do a bit more research on that before I fire out recommendations. Note to self...not all devices have the same setup as yours

Galaxy nexus CPU clock speeds 1.65Ghz!

just wondering what you guys are getting for clock speeds on your galaxy nexus, im successfully running 1.65 Ghz using franco's #18.2, stable and random reboot free, i would love to hear yours

What are your uv settings?
Sent from my Galaxy Nexus using xda premium

Weird I'm having trouble uploading from my app. But its 1450 mV for 1.65 and 1.6 1400 mV for 1500. i haven't done any undervolting yet, i dont want to mess with the stability, mainly because im happy my phone even runs on 1.65.

*Shovels dirt into the grave*

I myself not so concern about battery life loss from CPU OC as long as the screen is still consuming 50% of it everyday...

meh, i have a extended battery, get decent battery life and have an extra, so im not worried. and its not like im at a constant 1.6, im happy with it so far gonna use it for a few days and see how it goes

who cares about battery life when you have a massive e-peens!

Literally just got into rooting and theming with my first android (gnex). Rooted and installed aokp b25 with nova launcher and loving it!
Is there noob guide to over clocking? Or a go to app or anything?
Maybe a tutorial? lol

Google can be your best friend. thats how i did it

But....Quadrants must rule!
To the person who said they don't care when the screen takes 50%....
That makes no sense on why not to care about battery loss from overclocking.
Less == less, no matter what is draining it.

Thats how I rooted my phone and installed my rom. All googling, literally had no idea how to root or install a rom. Didn't even know any of the terminology.
Overclocking seems to be a bit more risky. I've tried googling a tutorial/beginners guide would be amazing.
What kernel are you guys using and where can I find it?

im using franco's #18.2 kernel you can find it in the cdma developer section

Does anyone find it amusing his CPU score is lower than a stock Galaxy Nexus and instead his i/o score is inflated?

generous use of of loading quadrant into ramdisk?

i noticed this too, i was gonna ask but i figured since all phones are different, it didnt really matter, but who the hell am i to say, your the expert...

I don't play the benchmark game, but ignoring your i/o score, your CPU score which an overclock would address is lower than stock 1.2ghz.

Nexus battery issue

Hi all. I have a gnex that has horrible battery life. I have tried using the stock battery and the OEM extended battery however I will only get about eight hours of use. I am running cm10 with lean kernel. I have overclocked, under clocked, and undervolted but has made no difference. I am including some screenshots so someone can try to help me or at least tell me I'm not alone lol.

How much screen time? Press screen in the battery option.
Sent from my SPH-D710 using xda app-developers app

1. Don't overclock
2. Don't use LTE
3. Keep your screen as dim as possible
4. CM isn't really known as a battery saver rom. Its more of a performance with stability type rom
5. Test out other kernels.
6. Check your apps to make sure you don't have one that's killing your battery
7. GPS should be off
8. Turning sync off will help too
Oh ya and questions go in the Q and A forum

If you're constantly in areas with low signal and data on, your battery will drain from trying to get a signal.

Well it seems like you're using the phone pretty hard on LTE with a 1.6ghz overclock... Sounds about right.

Yes, way overclocked. Is your phone actually using that frequency and is it stable. Lean exp. 5 can under clock on the low side to 180. Try that.
Actually your battery life seems quite normal.
Some folks are saying that Diet kernel gives great battery life. I haven't tried it yet. I'm wondering if it will slow my phone down too much. I'm loving the speed and stability of Lean kernel.

CPU Overclocking Efficiency

Recently I've decided to overclock CPU and evaluate efficiency in term of speed by using one of the famous and best FRANCO KERNEL.
So I've captured 1 minute 1080p raw video with stock settings (no mods or hacks to mediaprofile.xml file) and rendered file in Google Movie Studio in 1920x1080 aka 1080p format and High quality.
Consequently, the results were as follows:

As you can see the most efficient OC frequency is 1305Mhz. All above are way slower, cause CPU gets hotter and efficiency decreases.
Yes, do admit overall smoothness is by far better in comparison to stock kernel, but as you can see overall efficiency is not a deal breaker.

Maybe try the version with the overclocked gpu. I think this can have a big impact, I mean on the PC most of the work is done by the gpu so I could be that it's similar on our phones

it's said that the difference is so minuscule, the 512mhzoverclock isn't worth battery loss. I'm not talking about relative to Franco, the device's stock gpu frequency is 304. But if you see it that way, to each his own.

Unless the GPU has built-in hardware encoding or decoding for the particular codecs involved, and it's actually being used by the software, it won't play any part in video rendering.

Interesting.You could try the same with Trinity .
