Hi,
I am currently using an Arc S with DoomKernel 18 (1.6ghz) + Arconium 7.0 on .62.
I've used NoFrills CPU to set max at 1.6ghz and min at 0.3ghz but when I used the app CPU Spy I see the following: 1ghz 15%, 249mhz 47%, Deep Sleep 37%.
How come my arc s is never running at 1.6ghz? Is this because it never saw the need to and could perform at 1ghz or is it because it is clocked in some way?
Usually it depends on the governor you are using.
After you set the processor speed, try to reset the timer in the CPU Spy, which might help.

Is there a governor you recommend? I am currently using SmartsassV2 but it was initially set on interactive I think

Try InteractiveX ?

Smartassv2 works for me, just don't forget to tick the "set on boot" tickbox

Besides smartass governor what is the next best setting to use?
This is with GPA17 and Pete's modified kernel.

If you don't mind random wakeup lag I'd stay with smartass, ofc I can't tell you how BuglessPete did optimize his combo (ROM/kernel) in regards to a certain governor setting. My #1 is ondemand, #2 smartass.
I've been underclocking and undervolting and getting amazing battery using either ondemand or interactive, not sure what the difference between the govereners is, seems to me that clock speed and voltage seem to have the biggest effect on battery life, and performance wise I can't tell a difference between the different governers

Smart ass is good when you put your phone a lot of time in stand by mode,
Ondemand is the best

Thats what I'm using now. Thanks for the replies.

I'm assuming this all holds true for when using SetCPU as well? I have it set to max 800mhz, min 100mhz and a custom profile for "screen off" at max 400mhz and min 100mhz, all "on demand". I'm on stock rooted ROM GRJ90, kernel is by the pete alfonso dude...
smartass lowers the cpu when the screen is off. if you're always turning the screen off/on, this can slow down the phone/cause instability.
ondemand is very stable for me
This is just to help out those who are wondering what the majority of other xda members are using.
SmartassV2
Ondemand
conservative
Are so far peoples favorite governors
smartassV2 on Doomkernel for GB, works beautifully with sio scheduler, a great combination for our Arcs

Since ICS, Sony has implemented Interactive in stock kernel, so I use that and it seems to be helping a lot overally.

doomkernel + smartassV2 + noop for stock GB rom.
It's the best. no doubt about that.
No option for stock?
I mean surely that would be the most common answer, surely?
DooMKernel v4 ICS, SmartAssV2, SIO. Works like a charm.
Normally interactiveX, but on ICS it doesn't go over 1017MHz
Using ondemand atm untill that bug is fixed

I noticed that as well when I used CPU Spy so now I just OC with smartassv2 !
Atm I'm using brazilianwax, very smooth and fast andit doesn't stay at one of the highest frequencies like lagfree.
But lagfree is also nice
EDIT:
Using lagfree now.
I have the smallest lags with that governor. Well, performance has even less but that can't be a daily driver

ondemand here.
Can someone please explain the differences between the i/o choices. What do they do.
What settings are best for keeping good battery life and performance.
I'm on I'm on night kernel with the option to oc to 1.8ghz

Thanks for that. I'll rephrase, which combination of governor and io schedular give best performance and battery life?

InteractiveX and sio

So I was trying to mess around with CPU profiles and I noticed that the low end of the CPU is clocked at 1GHz. If I lower it with Rom Toolbox, it just goes right back up after I leave the menu. the profiles won't stick, governors don't make a difference, and I'm a little confused.
Can someone shed some light on this for me?
I thought the lowest speed was 384 MHz? Install CPU Spy and check what it says.
It is 384MHz. The lower frequency change because of project butter that make the cpu run at a higher frequency when you touch the screen.

Dont you need a custom kernal in order to change the clock speeds?
sent via xda premium with nexus 7
No, we can already change it but it won't stick since it has its own frequency management.

Is this somewhat similar to perflocker in HTC devices? It had to be disabled to change any cpu settings AT ALL with the stock kernel.

You're right. I guess it just has its own profile to set at 1GHz when the screen is on, because the CPU Spy showed it in Deep Sleep/384Mhz for the majority of the night.

Hello guys,
I'm here to ask for all of your opinions about the cpu Profiles, frequencies and governor.
For screen on I'm currently using 1200mHz on performance, I would like to know if it would save more battery by using on demand governor.
Some months ago I had a discussion with few xda members about this subject. But that was on aurora v4. Now I'm currently on v5 u17. Let me know your opinion. Thanks

To be honest, I've never experienced any benefits of setting cpu profiles for screen on, screen off etc. Your phone will work much more smoothly if you stick as close to the defaults as possible.
I don't use profiles. My min is 245 and max 1200, using on demand governor.
For a while I experimented with profiles, and had bad lag when unlocking the phone, and terrible battery use when screen on.
Independent of profiles, your governor will put your phone into deep sleep when the screen is off anyway.
Do a search for "race to idle" this explains in more detail the benefits of using ondemand as opposed to other governors in terms of battery use etc.
IMHO, Android as a platform would be far better served if people stuck close to the default settings and cpu profiles. Most of the time, any negligible benefits are just placebo.

So according to the race to idle running with performance governor saves battery
Sent from my U8800 using xda app-developers app
In theory yes, but if your cpu is always running at max frequency, ie even when doing nothing, then no.
I have done tests, and my battery always lasts longer using ondemand as opposed to performance, or other governors.

Use interactive/bfq that's the best in my opinion

I can reduce cpu voltage on all frequencies by 40 mV but gpu lags at anything above 450 mhz(performance governor), also I'm on doomkernel and I can't properly underclock for some reason...

If you do that all your seffings will go back to default like governors. There should be the option to set the same parameters on boot to keep all like you have right now. I don't know if on rooted Z1 there is this settings but should be because I remember I did all of this with android on different devices.

(I see a lot of people are using row though, so may need to test it and see if I notice a difference - that and undervolting..)
Current discharge rate is at 3.2% per hour and that's including wifi never being off, some gaming, instant messaging conversations and emails
