smartass v2 and ondemand are very popular on the XDA
Which do you like?
I think smartass is a better governor in my opinion.

Neither is going to make your battery bigger, lol. But I tend to use smartass. I think the key to saving battery is lowering your sleep CPU to as low as possible.

I've been using ondemand and smartassv2 each for a while and I haven't noticed any increases in performance or battery life. Every phone is different, so I guess you should just find what works best for you.
Also, performance wise our phone's processor is more than enough to deal with most things. I have rarely ever felt that I've need to overclock (unless I'm trying to get a quadrant standard PR ), usually it's an issue with RAM (once again, for me at least)
Not so big difference, but I think ondemand is better.

hey guys.
i'm on CM6 final with the Snap v7.6 BFS kernel (no turbo).
i use SetCPU, 499-998 ondemand and 384mhz for screen off. this works fine for using the phone.
i ran quadrant like that and i got 14xx...i put it at 1.19ghz (both min and max) and on performance mode...and got 1668...so about a 200 point increase in quadrant.
however, in both an3DBench and Fps2D i got a slightly lower score while overclocked then while on ondemand mode at 200mhz less??
is setcpu really doing anything then?
Every phone responds to SetCpu differently. I look at its purpose more for improving battery life than performance. Our phones are pretty snappy to begin with. Also, Quadrant is a highly flawed application. I wouldn't rely on that to depict how well your phone is performing.

I am not sure what exactly the latter 2 tests test but here's a guess : maybe they are testing the GPU performance and SetCPU probably does not affect the GPU frequency ? I know Quadrant is a bunch of tests that also include some CPU centric tests and that might explain the higher score.
Heya,
I've heard of this SetCPU program, and figured it has some solid potential of saving battery power.
My question is - does it work? I've read several post claiming that SetCPU doesn't work on HTC phones.
If it does - will using the "Mix \ Max frequency" mode will save battery during stand by and normal usage, or just slow down the phone?
Using Rooted Desire, LeeDroid 2.2d.
Its primary use is to overclock the CPU, its secondary use is to create profiles and reduce the clock or change the governor. This will improve battery life slightly but also decrease responsiveness, depending on how far you go.
You'll need root if you want to use it.
To really increase battery life you have to use a custom ROM with an undervolted kernel.
So you're saying that the saving in battery life is insignificant considering the slowdown in performance?
yes, you use LeeDroid which is undervolted, thus perfect conditions.
It also uses a custom governor 'Smartass' which gives you best performance while using it and limits the max. clock while sleeping. That's the most common method to increase battery life with SetCPU while maintaining performance. So no, you don't need SetCPU, LeeDroid handles everything perfectly already.
However, the Desire has a very powerful CPU, compared with other Smartphones. So you can use SetCPU to limit the clock to maybe 700MHz or 800MHz. This will increase the battery life but also reduce the processing power. If you don't play games, don't do a lot of simultaneous things or browsing huge websites, don't use heavy loaded homescreens, it's possible that you don't notice the reduced processing power.
Thanks again
I guess there is no damage to the SnapDragon if I lower clock speeds a bit...
But, if I want to do some overclocking - how far is it safe to go?
When I OC'ed my Q6600 CPU I used the TheremalRight Extreme 120 with two Slip Stream fans to cool it off.. So, will heat damage be a constant threat to an overclocked Desire?
I currently live in Israel, and it's hot as hell even on stock speeds

I for one has chosen to disable the default powersave in Auraxt sense, and then using SetCPU to control it, i get a day of power easily, and still goes to bed wit 50% power, that is with stock clocks on normal usage, but with minimum power (245) on screen off
Re overclocking:
To reach high clock speeds you also increase the voltage on your PC, else you can't increase the frequency that drastically.
Because you can't improve the cooling on the desire you have to keep stock voltages but also can't overclock that much.
The overclocking methods on the desire keep the voltage at stock values or even lower (defrost rom).
I don't know the voltage values for LeeDroid.
I it shouldn't get warmer. In the worst case it will crash and reboot until you reduce the clock speed.

Im running CM7 with ADW EX launcher and a 3500 MAH battery. I want to know how I should adjust the CPU for maxium performance? Any suggestions help. Thanks!
Whatever setting you want.
Performance will run the cpu at max. Best performance, worst battery
conservative slowly ramps up the cpu, usually good performance and battery
ondemand ramps up cpu quickly and slowly moves it down. better perfromance, worse battery (than conservative)
Interactive - tries to modify cpu a little more efficiently- performance and battery unknown (there is no known concesus as far as I know)
Therefore if you want amazing performance and dont care about battery go performance, if you want to use your phone more than 6 hours, go with ondemand or interactive.
Thank you

If ADW Ex feels laggy, download VM Heap Tool and increase the dalvik heap size. That always worked better for me than increasing the cpu - at least as far as the launcher goes.

How much can the phone be underclocked while maintaining the stability of the system?
What would happen if i set Max freq to 600 Mhz?
What is the best thing to do to save up the very last bit of juice in the battery for emergency situations where i would only need the phone and message facility? Besides switching off Bt,wifi,sync.
Im asking because i was wondering if underclocking "too much" saves a substantial amount of battery when my battery is quite low and I am "hours away" from a charging port!
And is there a way to change the carrier name on the notification drop down to whatever we want.
Sorry if i sound noobish or if a similar query has been asked before
Thnx.
Underclocking the CPU dramatically isn't going to gain you a great deal in the way of extra battery life because:
1. Unless you are heavily taxing the CPU (complex 3d games etc), the biggest drains on the battery are the screen and the radio.
2. If the screen is off, the phone will drop the CPU frequency right down anyway.
The best way to get extended battery life is simply to carry spare batteries!

Dave

I think 600mhz is way too low and counter productive or for that matter anything less than 1ghz. The phone will lag alot and you'll have freezes. You'll probably end up using up alot of the battery life trying to get tasks completed. You could try leaving the stock clockspeed 1.6ghz, set minimum cores to 2 and slightly undervolt to -25mv, leave the gpu setup to its default 533mhz and also undervolt to -25mv using a kernel that supports stweak app. Then run an app called Stability Test for 10minutes to check for errors.
Also I tried Go Power Master, which can be assigned to disable certain features once your battery hits critical low levels.

Thats quite informative. Thanx!
For the people that have been overclocking this phone for a while now, what are your opinions on the best max frequency above 1.5GHz to clock to while still keeping decent battery life?
Overclocking isn't exactly a battery friendly thing to do, you will see battery drain if you clock to higher frequencies. My only advice is don't oc too high if you want to keep battery life in mind. Going to 1.67 or 1.72 should give you a decent speedup without murdering the battery.
I run mine at 162 its no diff in voltage from 151 at least on uber kernel it is.. Also try to under clock the the freq until or happy and no random reboots
