Show your SetCPU Profile for the Legend

Hey everyone,
i think it would be interesting if we collect some SetCPU Profiles.
The App you can find here:
SetCPU for Root Users [2.1.0]
Maybe someone has found allready a good Profile for saving battery but having enough CPU-Power for a smothy work on the Legend?
I have used this Profile for a while, but i think through the overclocking there´s to much battery waste and no really noticable better performance with the apps i use.
Temp > 40° Priority 100
122min | 245max
Screen Off Priority 70
122min | 245max

245/787, interactive
That is all

122/768 ondemand....
Is interactive better than ondemand? I mean from fast response/battery life POV...

Main
787 max, 245 min, interactive
Battery 40%
600 max, 245 min, interactive
Screen Off
400 max, 245 min, Ondemand
Screen Off and Battery 40% both at priority 50

I read this in an other board:
From what i've read, "Interactive" is a bit more aggressive at ramping up CPU speed based on load, and is slower to drop off to "idle" speeds once the demand has passed.
"Ondemand" is a bit more conservative in the way it reacts; and will drop back to "idle" speed more quickly.
"Interactive" makes the device significantly snappier, at the cost of battery life. "Ondemand" will last a bit longer batterywise, however; the device will seem a bit sluggish at times.

245/787mhz
Can anyone tell me the differences between ondemand, performance, interactive etc.? I can't seems to find the comparison between these in google, xda etc.
Please help me! I'm sure there's people out there who wants the answer as well

[POLL] What's Your Overclocked Speed?

You might have already figured out that HD2 can be overclocked as high as 1.5 GHz on its powerful Qualcomm SnapDragon Processor. Many people run their devices on default clock speed, but there are few of us who overclock their devices to get max out of it. So i have started this thread to know what your max clock speed is and what governer are you using. Post replies below. Also, don't forget to mention your Phone's Temperature if available.
Mine: 1.2 GHz On SmartAss Governer , Temperature Usually Around 95F

1305MHz using interactive, temp alway @ 28°C even when phone get hot?? tho alway careful to let it cool down when it feels too hot.

I have underclocked ... to 720Mhz (interactive)
Performance is okay and saves battery live
Temperature is about 28 celcius.

1267, 768 when battery less than 30%, 422 when screen is off
On-demand w/screen on, conservative when <30% and screen off
Not great on battery, but good performance an no wake lag
CPU Load jump or whatever it is, set to 30%

Sticks with no overclock
using a rom which is fast enough and saves battery life, Dont see a point that needed to overclock CPU

Undervolted to 576mhz, for better battery life.
Runs smooth enough for all apps, including navigation and games

No overclock for me, don't need it, phone is fast enough as it is.
Clock speed: 998mhz (default), governor: ondemand, temp: n/a
Good enough for me sweet onough on may battery.
P.s. there seems to be no difference(performance wise) between rafpigna kernel oc'd @1.5ghz and tytung kernel oc'd @1.2ghz, when testing on linpack and/or other smarbench tools

[Q] [HELP] Setcpu Advice.

Using Kyrillos v6.0 OC.
I am experiencing a rather greater battery drain almost 1% for every 5 minutes as compared to Non OC version.
A new found love for games i want to stick to the OC version. Please let me know the Setcpu settings and profiles i can use for a better battery without letting down on the performance.
It took me a great while to unfreeze my phone. Turned out the phone freezes at 1300 original setting.
Thanks In Advance

Try a lower value. eg @1120MHz

Try lowering the MHz a bit or even better, try lowering the voltage for different frequencies. But in general, a phone at 800mhz+ is going to drain fast no matter what.

use this settings
use setcpu or nofrills with the following settings
max-1000 mhz
min-100mhz
gavernor-conservative

thanks for the info

@Kyrillos13 : And the minimum value ?

Does cpu frequency affects battery life?

The question is simple, the higer the freq. the more battery consumption? i am asking because i cannot see any difference from 1.4GHZ to 1.0GHZ, the battery consumption is the same under oxygen and francos kernels. i would be grateful if the experts would give us some advise or their opionion. I know it is subjective but i would like a second opinion.
Thanks alot guys

If you look with any cpu spy app, you cab see on what clock the processor is used. I mainly have it the lowest and sometimes higher. When you change the max, it should still automatically choose what clock is used, so battery should last as much as before, if not used in high clock.

Probably not much difference, when you overclock, think the cpu voltage remains the same as it is on 800mhz... And the highest cpu freq is rarely even at use...

Well, thanks to most devoted users of U8800, we have somewhat better speed+battery life than stock also. To answer your question, yes depending on your activity the frequency have some impact, but overall shouldn't be huge in change, for example from .800 to 1.0GHz will not affect so much in daily use. However from .800 to 1.5GHz would make a somewhat huge gap difference. This doesn't mean it will drain faster if you do same activity as with .800 to 1.0GHz, for example check the watch, answer sms or few "entertainment" breaks. Only when using the phone over a longer period of time that's when you will notice the change of battery life with different frequency. Hope it clears up most hums and huhs for you. I am pretty sure some expert within this field will give a better explanation than me.
Bye~

higher freqs uses more energy, but lower uses less energy but do things slower (so energy consumption is longer). ALSO imo - if you set cpu to 1Ghz the lowest value so it always is 1ghz - it will not consume the same amount of energy if it's in idle mode - it's like your laptop - if cpu is working only in 4-7% of it's power - then the power consumption is lower no matter what freq - how do we know that? - because of heat - the more heat you get - the more energy was used. and when cpu is idle - it will not be hot.
So the answer is - if it saves then in VERY minimal amounts. But even so - i use min freq - 360mhz. it's good for me i do not get any lag so i use it.

I use the "Root System Tool Free", option CPU and I see the graphics of all clocks.
For ex. now at 245 mhz ->46%, at 368 ->10%, at 768 mhz ->18% .... and at 1612 mhz -> 1,8%, at 1804 mhz ->4,9%. Not very mutch use at 1804.
Oxygen-test-140911 + Franco.Kernel1709#1. Clock at 1804 Mhz by Menu-settings-cpu ... and smartassV2 (no profils).
The battery, I charge it all 24 hours. But I like my work... and testing things. When then will dead...I see...

But I like more the Root System Tool, because has also a Linux Console. I use it when I want make some cmd's Linux in #. I don't like the Terminal Emulator.

Well, there is a "catch" somewhere in there. The frequency does indeed affects the power consumption of the CPU and greatly at that too! But the thing is, your CPU is not the worst enemy of your battery life. Even though CPU consumes more power in higher frequencies, it still can not compete with what your screen LEDs or your GSM module or your GPS chip consumes leisurely. So, if you're looking at the overall picture -meaning if you're wondering if it will affect how long you'll be able to use your battery in your phone- the answer is, "yes but not so much". Especially if you're switching the CPU frequency based on the demand (like using smartass or on-demand governors)
Here are the thing that sucks your batteries life juice like a vampire :
Your Screen (especially background LEDs)
GSM module (talking, using GPRS/Edge/3G network communication)
GPS chip
Wireless module (this also includes Bluetooth, even though it does not consume as much as Wireless network access but everything is relative -think about playing music through A2DP headphones compared to having your wireless network active but not using it much-)
(oh yes, I love to use lots of parenthesis -and even this hyphenation thingy- )
Correct me if I'm wrong about anything by the way ..
Regards ..

I did some experiments with a msm8250 a while back and there's a graph here:
http://forum.xda-developers.com/showpost.php?p=14324649&postcount=3786
msm7x30 should be fairly similar though the graph is probably shallower since it's a smaller process size.
The CPU uses no power when it's not in use, even with the display on, the CPU is powered down completely when idle (power collapse).

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.

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.
