The Best SetCPU Profile?

What's your profile setup?! Here's mine:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
(Using Kingx's BFS kernel #1, btw)

Why did you change all of the "on demand" defaults? I never understood the difference, even after reading the release notes.

this will be interesting to follow, just installed this app...

I use conservative.. It's a good medium for performance and battery life.
And for screen off... powersave.

I really don't know the difference between all of the governors, is there a list and a description of what each do?

i've just started mussing with it.
due to the version of the -snap kernel, i am using conservative as per dev notes.

Using Netarchy-Toastmod 4.1.2 I only have Performance and Conservative.
main: Max: 998 Min: 245 (Conservative)
Profile: Screen Off: Max: 245 Min: 128 (Conservative)
Quadrant: 1281

Seems to be missing some. Like "interactive". Hmm. I tried doing a search for it but its just release logs of adding it.

I don't use profiles because they seem to slow my phone down like mad.

ALL credit goes to shift_
temp > 50c = 422/128 powersave (priority 100)
screen off = 384/245 powersave (priority 98)
battery < 20 = 499/245 powersave (priority 91)
battery < 50 = 768/245 ondemand (priority 84)
charging/full = 1152/768 ondemand (priority 82)
battery < 100 = 1152/768 ondemand (priority 76)
This is the current on i use on cm6 rc2

Heres mine. I just got setcpu, and im still tweaking it, but this seems to be working well.
and to the op, you know your 65.2 degrees C is like 145 degrees F right? I might be wrong, but wouldn't the phone be getting heat damage well before 145 degrees?
And also, I downloaded JuicePlotter, it really helped in telling me how the battery life was affected.

Anyone else going to chime in?

here's what i got, had this setup for a while and so far it's working great:

the governors have to come from the kernel right? bakedkernel 2 doesnt have conservative or powersave. is there any way to add them?

Using 4.1.8 bfs/bfq fresh compatible kernel so far smooth, no issues, satisfactory battery life.

I am Running 2.3,
What profiles should i use? this look alright?
And is it really worth using?

i like the screen off profile, as that makes a real difference for me in battery life, however i see no point in having battery profiles. do you really want your phone to become slower just because you drop under 50% batt?
normally i would want it to keep going full speed and in the case that im on the road and need to save battery as much as possible i would change the setcpu profile myself (and probably switch off sync and 3g)

Your <30% profile will never kick in, since that is also <50% which has a higher priority.

Newb question: Does one have to have a rooted phone to install Set CPU?

^^^ Yes.
SetCPU needs superuser privileges to do its thing.

Priorities fixed now, I used it with less than 50% and the phone was just as fast doing regular tasks and web browsing

Am just using screen off dont need to use any other settings.

You also need a custom kernel, the htc one can only underclock not overclock

I just use <30% battery, 768Mhz. I let HAVS do all the rest.

So because I have a custom Rom Leedroid, I dont need to disable the driver?

What is HAVS?
Also, what's better for batt conservation (w/out sacrificing speed): Undervolting or underclocking?

HAVS is a set of instructions from the kernel governing the CPU, it undervolts and under clocks the CPU when it is not in use. Undervolting and underclocking go hand in hand.

I have just 1 profile:
screen off: max around 384 MHz. and mim 245 MHz.
Does that makes sense? :-O

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

Slow/Laggy CM9 Nightly Fix!

I'm not sure if anyone else was experiencing lag from the new CM9 Nightly like I was after I flashed it.. So I played around with the options and noticed that the CPU governor under "Performance" was set to "Interactive". I switched this to "On Demand" & checked "Set on Boot" and man this phone flies now! Also make sure that the min and max speeds are set correctly.

I dunno, maybe your battery life is going to suck now lol. Let us know how the drain is. If I weren't at work right now I'd be playing with the latest nightly myself.

CM9 is Great! Flashing LU6200 and used X2.

You have succesfully flashed CM9 on LU6200 ?

On demand governor draining more battery then interactive one?

Much snappier for me too. Can't report on how it affects battery life yet. With this phone and the newness of the ROM, definitely keep your charger handy.

thank you, I made these changes.
I did a bit of the google to try and find the difference between interactive and on-demand, the nomenclature sure seems similar, but could not find any descriptions of the 2, anybody know?

http://wiki.rootzwiki.com/CPU_Governors
Ondemand
Quickly scales up the CPU frequency once there is sufficient load, and then quickly scales down the frequency once the load is no longer present.
* Pro: Good performance, decent battery life.
* Con: CPU frequency can constantly shoot up and down, causing more power drain than staying at an "ideal" frequency.
Interactive
Quickly ramps up to the maximum allowed frequency, then slowly drops the frequency once no longer under load.
* Pro: Faster to ramp up and down means a snappier response from the device.
* Con: CPU will run quickly for a few moments after it is no longer needed to do so, resulting in longer periods of higher power consumption and heat generation.

I don't notice a major difference in battery drain yet. Still mediocre. But I am willing to sacrifice some life for the absence of lag. I almost reverted back to gingerbread before discovering this minor change fix lol.

Thanks Namuna

THANK YOU VERY MUCH FOR THIS
actually i have a much better battery right now and an almost lag free phone !

I do not recommend enabling KSM as posted above. I found out that ksmd process utilizes cpu by 3-5% for hours!!! It drain battery on my eyes!

[Q] HTC reduced cpu frequency in update?

Hello, I heard that HTC reduced the processor frequency in "One X", due to the high temperature of tegra and battery lifetime (In update, maybe 1.29?). Is that true?
Sorry, but my english isn't good.

not reduced just doesn't ramp up as often as before

Thank for answers
I didn't know that antutu shows the cpu frequency

antutu only shows what the max speed is and its only 1.5 on a single core, when on 4 cores you can only get 1.2 GHZ and 1.4 GHZ on 2 cores.
look at terga stats at bottom on screens
4 cores bench

So reduced frequency it's true? Earlier (after updates) unless Tegra 3 had 1.3ghz on 4 cores ?

No It's always been like this, the update changes how the CPU speeds up and down e.g 50 MHz in idle to max speed, all its done is help the phone use the lowest possible speed to save battery.
