Would everyone mind sharing what your choice for all round performance / battery life is? So governor, kernel, and anything else?
Also, anyone know the difference between ondemand and ondemandtcl?

I'm currently running the latest non oc/uv of dead horse, and I wanna know what exactly are the benefits of overclocking/undervolting?
I'm already getting really good battery life with the current kernel I have.
Thanks in advance!

Basically Overclocking makes the phone faster at the sacrifice of lower battery life, Undervolting improves battery life potentially at the cost of processor speed. The proper combination of the two can give you a faster phone with the same or even improved battery life. (very basic explanation i know)
Using setcpu, correct?

I don't think under volting has anything to do with processor speed. I've under volted quite a bit before with no drop in linpack or quadrant scores. If you drop the voltage too low it will cause the cpu to freeze though.

As I understand, underclocking will only help you slightly, you're better off using apps like Juice Defender or Green Battery (forget the actual name) to help with battery life.
I use Juice Defender. And the profile I use is screen off with minimum and maximum clock speed at the lowest setting and the priority to 100.

Have you tried going lower?
My current battery saving setup:
Rom/Kernel: joker skinny 1.3 / joker 1.4 oc beta ext4ready wifi highpro
Battery Saver Mode: Maximum
SetCpu Main Clock setting: 216-750Mhz (with joker's tuning @ 750 it benches about the same as a bone stock MoPho)
SetCpu Profiles: Screen off= 216-456mhz, Charging (think dock use)=216-1400Mhz
Undervolt:
1.4Ghz=1200mV (-100mV)
1.2Ghz=1100mV (-100mV)
1.0Ghz=900mV (-100mV)
750Mhz=750mV (-125mV)
456Mhz=650mV (-150mV)
216Mhz=595mV (-175mV)
RESULTS: battery is at 94% after 11 hours of standby with WiFi OFF, 3G ON and good signal levels. This includes checking the time a couple of times and my alarm this AM. The best I could ever get with my super tuned OG Evo was 1% per hour of standby.
Wow

Would I get better speed if I disabled 1ghz frequency and left 1.2ghz the default Max frequency?
Would it be faster?
Or slower? Or nothing?
Don't like the 1ghz frequency. But I notice my phone is a little slower when disabling. It.

Good to see enyo has found where he belongs in xda. Asking questions and learning.
This is a big improvement enyo.
as to 1.2 feeling slower, your putting a massive undervolt on it. Try backing it off a bit and see if responsiveness comes back. Also, higher clock speeds can lead to better battery in theory by completing tasks faster and allowing the CPU to govern back down to a idle state.

Thanks. Your right. Backed to -75mV on 1.2ghz and faster response came back.
Also it because really fast after switching to the Medium Leakage.
I rarely let my phone sleep, so 1.2 is the maximum I'll go for speed/battery.
But, the more you UV, you get laggy if its too low, but stable?

Honestly -50uv across the board yields the best performance, battery life and reliability.

that would be called overvolting... yes performance may increase, but inturn added heat, less battery life and instability can occur with it.

So -50mV is just enough?
I'll do that. Your good with setups of oc/uv.
Seems really stable for me.
Trying Low leakage for better battery. But Medium is perfect right

just tried your setup. And I didn't know how slow my phone was till I used yours. So undervolting to much does slow down your phone. And it Got hot out of no where.

Why there is not dev try to plug different governor for user?
Sent from my MB860 using xda premium
I may have this wrong but I have read in earlier posts that the power managment on the tegra 2 is only set to work with the perfomace governor. It was tried with the power save governor but that had no effect and was actually more power hungry. I will try to find those refrences when I finish work.
Sent from my MB860 using XDA Premium HD app
thx!
Tegra 2 has a built in hardware governor which is pretty good so there is no need to install software governors, in fact, installing a governor other than performance will impede performance and/or battery life by interfering with the on chip governor.
I believe the Tegra 2 drivers control the CPU speed. It overrides the governor. Performance and powersave are the simplest governors.

In was just looking into this. I'm on neutrino, and no matter what kernel I seem to have, my CPU is locked to the max frequency. My battery life has been brutal and the phone gets too hot even after sending an email!
What is wrong?
Sorry for the ETA, and but I should be more clear..
When I open setcpu or antutu cpu master, and both report the highest selected cpu frequency constantly no matter what the conditions are.
Is the fact that I'm running a java application to control max frequency interfering with tegra 2's governor? Although I've see screen shots of atrix users in setcpu with the freq being not-the-max-freq.
Thanks for any help!
Note: I only ever have one over clock app installed at a time.

I think they're both great you can't go wrong with either kernel. It's like choosing a lamborgini or ferrari, they're both awesome but it truly comes down to preference.
I think I got better battery with faux 31 but I under clocked and undervolted so I can't do a fair battery life test.

I've noticed better battery life as well; not majorly, but noticeably. Although I feel it also has a little perfomance drop. Could just be me, though.

Don't worry.
Undervolting is basically adjusting the voltages so the cpu uses less voltage aka electricity. It helps a little but it can make your phone unstable so watch out. Of you undervolt use the system tuner app on the market. You should definitely under clock if you want to save power too. When you undervolt be sure to underclock, and don't do it too low or your phone might freeze! That's why your shouldn't go so extreme on it.
Overvolting is basically adding more voltage to the cpu. There is no point in doing it for our amazes to be honest. It is already a battery hog. I guess it can help if you want to over clock a lot but there is absolutely no point in doing that.
In older legacy phones if you wanted to over clock because the cpu would be so weak, like 600mhz then you would have to overvolt to over clock to like 1ghz if you were lucky. Our devices are 1.5 ghz dual core and sense isn't THAT bad. There's no point in doing overvolt in this phone though.
PS, check out my rom in the development section.

I just saw it in Venom Tweaks and was curious. The most I underclock to is 1 GHz; cuts down the CPU maximum by a third and doesn't hinder performance to much. What voltage would you recommend at that clock speed?
P.S. I have I plan on flashing it to try it out when I get WiFi access. Trying to cut down data usage since I don't have WiFi at home.

1ghz is perfect. As for voltage it really varies but I subtract 75 or 50 mv from all voltages.
