root rookie here.. First device I ever rooted, really I'm new to cell phones in general.
I flashed this rom adryn bamf 4.1 (non remix) and its working good and all
But I noticed on the smartass setting, which underclocks, that after about an hour or so of playing a game/tv whatever my batter will be around 42C, it seems very hot compared to around 32C before I put this rom and kernal on
Two questions
Am I doing something wrong or is this normal
And, How hot can a battery get before it becomes something to worry about?
Thanks =P
Yea in the 40's is way high. Remember, heat is inefficiency (wasted energy). After playing a game for an hour you will probably be in the mid 30's C. I would recommend trying a different kernel and wiping devlik cache. Also, see what apps and services are running in the background and increase the length of time between syncs. Also, smartass scaling did great on my incredible but I have found that it is not perfected yet for the tb. I would suggest ondemand unless the dev or OP specifically says that smartass is the way to go. As far as heat and battery I find that adrenylyn's kernels do the best. As far as performance, drod and ziggy's seem to fly. Isoman or whatever seems to also be a favorite but I personally didn't have great results. It is important to not supremely OC or UC. I would simply stray away from UC in general. For a daily driver, I would stay under 1.5 Ghz, and honestly 1.2 seems to work best for me. Hope this helps.
thanks for taking the time to respond
So why no under clocking? I assumed it would help battery life but not so much?
Just set to 1200 for both min/max? Or on demand scaling up to 1200?
I prob had a bunch of apps running in the backround, i'm new to droid.. came from an old feature phone
42C is definately too hot! As the previous poster suggested, try a different kernel. There also could be a remote chance your battery is defective.
I really feel like it is more likely that something I am doing is impacting it
I had the phone stock for a week and no problems (same usage)
Rooted but stock rom for a week and no problems
Put this kernal on (which everyone says is really good) and this rom and it was getting hot.. So far it is good around 38-39 (still too high?) with 1200mhz on demand min 256mhz
I flashed 2 different kernals and both times after less than 45 mins of browsing forums and playing home run baseball my battery gets to 42C. Could this be caused by the rom? I wonder if I damaged my battery or phone at this point
Mine got up to 113 degrees over the weekend. It felt like I was cooking my phone off and getting ready to throw it like I do in black ops.
I realized my phone was trying to search for a 4g signal when there was none. I entered #*#*#4636#*#*# on my dial pad to turn it off. It reduced my battery heat by 5 degrees. I should point out I was out in the field. Aka in the middle of nowhere where.

I'm @ 53.4C right now and it doesn't seem to be charging, lol.

Sorry but to fly off topic what do you do? I'm generally out in the boondocks when I'm on wellsite...

42c isn't anything out of the ordinary, or outside operational parameters for a battery of that type. Not by a long shot, actually. That battery can safely operate at 59c, but the phone won't charge it north of about 47c due to the fact charging will increase the temperature even more.
As for the governors:
The smartass governor operates similarly to the interactive governor, but isn't as aggressive and allows for wake up lag reduction. The governor SHOULD be your main line of controlling clock speed, not your min and max settings. Some might like to argue that point, but that's mainly because they haven't messed around with governor parameters. With and ondemand or interactive governors, and even some smartass governors (Not Ziggy's modified), it's entirely possible to set min as low as 61MHz, and max at 1.65GHz and have the CPU rarely, if ever, reach those speeds. It depends entirely on what you've set the governor parameters to be. I don't know of any app that allows you to modify those because the locations of the parameters aren't always the same name or in the same places so it's best done through a script. The script I uses does routinely reach up to my freq_max, but it does it fairly aggressively, then ramps down just as aggressively. Part of that is the nature of the lagfree governor, part of it is where I've set the thresholds. In any event, governor control via a script is a much better solution than castrating your device.

If you are using one of the Over-Clocked Undervolted Kernels please uninstall set-cpu and observe your battery life for 3 days and compare it to what you got when you used set-cpu. Then report as to if it is better, worse, or the same.
Just compare to what how long your battery lasts with your normal usage. Please do not give replies like "I only used 30% in two days with normal use."
Just reply with either better, worse, or same. Because usage is relative and that is not the purpose of this.
I think that set-cpu is interfering with the built in govenor and its ability to scale the freq of the phone. I think that it is staying on what-ever freq you set in set-cpu and scaling properly and thus reducing the battery life, and making the undervolting useless.
IF YOU BELIEVE YOU HAVE BETTER BATTERY LIFE WITHOUT SETCPU, THEN GET LOGS WHILE IT IS RUNNING AND SEND THEM TO THE DEV.
I have also noticed lag on the home screen with setcpu, I started using Overclock Widget to detect the values and to diff freq screen off 245-576 and put the phone on sleep while charging so will stay cool. Battery life has been great so far! I'm using 2.6.33.4 [email protected] #1 about to upgrade to his newest 2.6.34...I think SetCpu has flaws!
Will let you know my results.
this thread may be of some help. im currently trying pershoots 5.12vfp release without setcpu at all.
i do, however, remember getting 37 hours with moderate use with setcpu and profiles set, but i cant remember which kernal it was exactly. i think it may have been IRs 4.29 release..
Just uninstalled SetCPU and I'm running Pershoot's newest 2.6.33.4 925 Kernel. I will report back my findings in a couple of days...
Been curious about this for a while, but does the Nexus automatically throttle CPU speed by itself when SetCPU is not installed?

When you don't have setcpu, you're not running at 1113ghz..

Perhaps...However, Linpack is proportional (I think) to the device's performance. My little experiment was testing different frequency kernels and measuring that against Linpacl
998: 7.4
1.13: 8.2
1.19: 8.9
So it would appear that performance increases with each kernel which wouldn't be the case if SetCPU was required.
I have some reasons to believe that SetCPU would interfere with the actual design of the Nexus One. I mean after all, i'm sure it was programmed to manage itself. So why have another app that does the same thing, twice? Just a thought, but for one thing, my phone is definitely cooler when charging compared to having SetCPU with profiles.

There are dozens of potential optimizations that can be done to improve performance without touching the cpu speed. Different kernels, especially if they're from different people, will have different flags set in the build and so will perform differently even at the same clock speed.

I completely agree however all the kernels I use are from the same person and the optimizations at the different clocks speeds are identical. Therefore the spread in my linpack scores indicate that setcpu is not required. At least, that's my theory
this and other threads have made me question why we need setcpu anyways. I have it running and its great but can't we just integrate what setcpu is doing from the get go instead of having an external app running a separate process?'seems a little inefficient to me. The reason I say this is that I noticed most people are using the same settings for set cpu.
anyways, I dunno how relevant all this is since froyo's just around the corner and that may alleviate some problems but bring more problems
Yeah, start bashing my app, knowing I was the one who came up with the ideas behind the 1113MHz/uv hack in the first place (in fact, I came up with the 21MB hack as well, so prominently displayed in the OP's kernel thread title). Thanks, nexus one community.
I can explain that setcpu does not run any code in the background if your profiles are disabled, I can explain how cpufreq works, I can explain what lengths I went to to optimize the profiles, and I can explain that the profiles are very passive (except sometimes on the Droid, but there's an option for tweaking that) but I probably won't bother. Grab 1.5.3a and use it, or don't use it. I don't care either way.

You obviously do not know how cpufreq works. Setcpu does not touch the values after it sets a profile. Profiles actually run code only when it receives broadcast intents. It sets the max and min bounds and the governor if necessary within a fraction of a second. The service is completely idle otherwise. It can't "interfere with the built in governor." Okay, then. What is your big theory? What exactly is setcpu doing wrong?
SetCPU is advantageous because it allows you to tweak speeds on the fly and based on certain conditions. You can have solely kernel based overclocking and undervolting, sure, and that is perfectly fine. SetCPU is a convenient tool for controlling that without having to compile and flash a new kernel. If you do not like profiles, do not use them. They were only introduced in 1.3.0 But don't uninstall SetCPU because it does nothing with profiles disabled.

HTC implements a rather awkward driver in nearly all of their Sense UI devices (and I think the Magic 32A) that throttles based on certain conditions. I am not entirely sure how it works, as I have not looked into the specifics, but it seems to max out the CPU under some conditions.

I am 100% sure this is placebo effect. Setcpu can't make your phone run hotter just because it's there. If you had a charging profile set for 1113/1113, sure, but that is not setcpu itself. Linux does not control the CPU scaling any further than what ondemand does - there is nothing preventing the CPU from going up to your max during sleep (or rather, when the screen is off), for example, or when your battery is low.
Oh, and using the active widget is a bad idea if you care about battery life. I tried to optimize it as much as possible, but realize that it's updating a lot more things than other apps are (the frequency, the bounds, and two temperature readings) at a relatively fast interval. The home screen does pause a bit while it is updating. That is a fact of life. Longer intervals are essentially useless because the update interval for cpufreq itself is on the order of thousands of microseconds. The current appwidget refreshes if the screen is on, regardless of whether it's visible or not (there is currently no way to tell if it is visible). A live wallpaper would be a much better idea than a constantly updating appwidget, and I'll look into that.
Let me explain this bit better. Cpufreq will scale your CPU between the max and min values automatically. Once the CPU load hits the "up threshold," it takes your CPU frequency from the min to the max, then gradually eases it down. SetCPU lets you easily change the max and min values on the fly. If you want, it can also prevent the system from scaling the CPU up that high during times you don't want it to (with profiles, of course). It does not and cannot interfere with the actual governor.
Well there you have it, straight from the source
TL;DR - setCPU doesn't run code in background unless you use profiles, it doesn't make your phone hotter unless you use a 1113/1113 profile, & if you value battery life don't use setCPU Active widget.

Props dude. Keep up the good work.
To be honest I'm a user, donator and supporter of SetCPU. I've never had cause to complain.
Not bashing your app dude, in fact I have the paid version. I am only wondering why people are noticing better battery life without it than with it. Want to see if it really is setcpu or something else. To do that something has to be isolated.
And I believe that if the freq are set in the kernel then the phone will scale up an down on its own.

I too am a fan of setcpu, and over the last week I did get curious due to this this thread. I found my battery ran down quite significantly faster without setcpu, maybe because I didn't have my sleep profile of lowest freq min/max, or my battery profile of max 756, or my low battery profiles scaling down my cpu max. Either way, stop bashing the app, it's awesome, and if you had concerns, take them to the dev rather than start a witch hunt in the forums trying to make a posse.
People that report better battery, may not have had setcpu set up correctly in the first place. A friend of mine at work installed it, ran for a day and uninstalled it, citing it didn't do anything and infact drained his battery. He had the widget running, and had upped the minimum cpu freq to 500 and something, max to the 1.13ghx. He didn't run profiles. But as such, he wasn't letting his phone scale down to the lowest freq when it wanted to, and had the widget drain. I got him to set t up as I have mine, and he was blown away with the change.
"My car wont go over 20km/h"
"Are you putting your foot on the accelerator?"
"Whats an accelerator?"
Things have to be used correctly to get the best out of them, and unless someone saying it's far worse than without actually comes in and puts up their values they have it set to, we have no idea why they are having the fault. My experience (I have worked tech call centres for years) is that 99/100 issues people experience are due to not using things as they are set out to be, or just have no idea how to do what they are trying to do. My work mates thing was that he thought all apps would go faster if he increased the minimum freq, so therefore use less battery because the processes are completed faster. In a way it's logical, but the result is that even when nothings running the cpu wont fall below that value, so the battery drained much faster than he expected.
Hi guys!For the last few days(that I have my Hero rooted that is) I'm using VillainRom 10 as my everyday ROM and have tried some others.Anyway,that's not the point!
Being one of the lucky ones whose Hero can happily overclock to 768 I came to use RaduG's extremekernel and ben39's no-bfs no-whining kernel.With the second,while configuring OverclockWidget I saw that it gives a 848MHz option with auto-detect frequencies.Is it possible?I'm not asking about stable daily use,but even for some minutes for benchmarking?Has anyone achieved it?Without making their phone catch on fire that is!
And secondly,why are we all using linux 2.6.29(for total newbies I mean the kernel) while there is 2.6.32-33-34?Can't a newer kernel be compiled for use with the Hero?Newer kernels would provide native ext4 support and would probably prove to be better overall.
Oh,forgot one more!I am currently running on minimum 176MHz-maximum 749MHz(after I got a couple reboots with 768 I abandoned 19MHz for stability) with screen on and minimum 123MHz-maximum 384MHz with screen off.Should I give it a higher minimum frequency?Sometimes it lags when waking up,the screen turns on but shows nothing but black and turns off again or it turns on and everything is distorted,colors are completely distorted,background is upside down and some other unnormal things,but everything is alright when turning the screen off and back on again.Does it have to do anything with the frequencies I am using?I am running on VillainRom 10.3.
Now I have set the minimums to 160 and 190 MHz to see what happens!
Thanks in advance!
About the high MHz... I have done it with over 800 but don't max it out at 848 or your phone will freeze but anything below works And that screen **** I've also had and it has something to do with the high MHz (don't know why) but it helped me to set the MHz lower when the phone sleeps in SetCPU And at last about the kernel... It runs on the old one on Android 2.1 but in 2.2 it will be upgraded to ....33 or ....32 don't remember which...

Thanks for your reply C0mpu13rFr34k!
I know Eclair is running on the old kernel.I just would like to know if it is possible to compile a newer kernel for it.
As for the frequencies...Are my settings alright?Some too high or too low?The way I see it there is a big gap between maximum and minimum frequencies when screen on which results on the CPU working at low frequencies most of the time,thus sacrificing performance.But it helps with battery life and presumably this and the screen-off underclocking reduce the overall damage caused to the CPU by the overclocking,which is said to reduce the CPU's total lifetime by 50% or more,depending on how much you overclock it.Working at 749 I sometimes get a nice 43 degrees Celsius while charging,but that's only when charging.Average temperatures are 30 for standby and 37 with screen on(average,can be lower or higher).
And one more question.At 800+ how hot does it get?Will it be stable for some minutes to do some basic benchmarking or nah..?
Thanks!

If your phone is stable your settings are just fine even though your phone might have problems waking up if the low freq is under 246MHz (something like that) Also if you want better performance you might want to test some other freqs and then benchmark... Sometimes it makes a BIG difference if your phone is running at 691MHz or 710MHz For me my phone works like **** if it runs at 749MHz but it works like a dream at 729MHz (I think the difference was 0.5-0.8MFLOPS) Im also pretty sure your temp is fine (OC shouldn't make your phone that much hotter since the voltages in all ROMs are adjustet). If you should compile a newer kernel you would first of all need a .32 (.33?) from HTC because of hardware capabilities and im sure there's is A LOT more things devs need to compile such a kernel but i don't know to much about kernels I don't really know that much about 800+ because I only did it once and benchmarked it (MFLOPS was **** and i couldn't get them high at all) actually it slowed down my phone but you should test it. Maybe your very lucky and your phone can take it
Well,I have set it to 653min-749max with screen on and 160min-352max with screen off.Testing only!But it runs like a dream if we don't take into account a small lagging when I turn the screen on and it has to change frequencies!But it's great so far.Will see how battery life goes!By the way,tried 800,806 and 848MHz,but none worked.It didn't crash or something,it just wouldn't change to it and stayed at lower frequencies(low as 246).
Thanks for your time anyway!
And a small question...How bad does overclocking affect the CPU's life?I asked around and was told that the maximum overclock for desktop PCs is 20-25%,depending on the CPU,while needing special cooling systems,and that it can reduce the CPU's life up to 50%.Given that we overclock over 40%,how bad do we damage our CPUs?

I haven't heard to much about that actually but from what I've heard it shouldn't damage the CPU at all because of the voltage adjustments but i find that very hard to believe... Talking from personal experience my phone runs as smooth now as it did when i bought it so my CPU has probably taken minamal- or no damage at all and I got it when it had just come out here in Denmark (Europe) which is about 8+ months i think? So I wouldn't care to much about the lifetime since It's probably like 1-2 years and by that time I don't think people are using the Hero anymore Keep up the good work with optimizing and your welcome
I use SetCPU to help battery life but someone told me it's not needed on the SGS2 as it already scales CPU for demand. True?

Interesting point you raise actually.
I've just installed Setcpu and used the on demand governor. I left the values as default (200mhz for minimum and 1.2 ghz for maximum) - with no overclock.
I've immediately noticed swiping through the screens is a bit smoother and the biggest improvement is the gallery. All my photos appear much smoother. Before the gallery app was a bit lagy.
I haven't set any profiles yet such as screen off.
Every Android phone I've owned scaled the cpu, I think they all do. I've found that with setCPU my battery gets drained much faster en no real benefit in smoothness.

Have you tried this yet though on the Galaxy S2?
There is definitely less lag than before - as stated, specifically in the gallery app. Just generally swiping feels more responsive as well. Battery is still pretty awesome, especially when using Lightening Rom 1.1 and the Android battery calibration app.
Hmm. I'll try SetCPU on the SGS2 and post back the findings (Performance+Battery).
I don't know how can it get any more smoother, I mean its already SO smooth!
there are many points to use setcpu on gs2:
-for some reason I dunno, gs2 can't manage it's 1.2ghz without gettin too warm. downclock and get rid of the burn effect.
-gs2 sports a good management of gpu (it does most of the work and setcpu doesnt down\overclock that). downclockin doesnt affect UI or video o browsing experience at all. can even downclock at 500 max speed without any sides.
-the only side u ll see it's benchmark (quadrant downgrading to 2000) but I hope u won't pay attention to such an unseful thing. benchmark doenst mean nothing, daily usage it's the only point to look at.
my settings: conservative, 200min 800max.
battery draining doesnt belong to setcpu this time, look to other settings.

IT IS TRUE. I agree with every single line you wrote, it is just my expericence.
I have too setcpu conservative and undercloked 800 Mhz.
There no slow down or lag at all... But I am wondering if it gives a real boost to battery life. I am not sure of this.
I'll keep you guys posted... But I think that an undevolted Kernel it is really a need as for the solution of the damn dual core ginger bug that is sucking 20% of my battery every day
Well,from my experience with my Desire and Desire HD(won't even bother with the Hero,I had no real knowledge then),governors can make a huge difference.I for one like smartass or interactive governors(mostly the same).I wouldn't suggest conservative,interactive does the job much better.Tasks get done in less time and the CPU throttles down more quickly.Other than that,you can underclock or overclock all you like,it never made any big difference in battery life for me(Unless Sammy's CPUs are different in that aspect-Snapdragons are really "overclock-friendly").That's personal preference after all!
Anyway,the best solution IMO would be a vdd_levels interface.For those who don't know what it is,it is a mod made by -snq(Meet him at the Desire forums-That guy's a true LEGEND!He can patch/modify anything!),which practically allows you to change the voltage levels of the CPU on the fly rather than having to stick with the values hardcoded into the kernel.Using this and a simple script in GScript to change values that won't survive reboot or in init.d to be applied on boot,you can find the optimal voltages for your CPU(Don't forget,every CPU is unique and different),thus reducing heat and maximizing battery life.
If a dev brings that to the SGS2 it will be a big step in the right direction as far as I'm concerned.
I use SetCPU without issue, but only to run profiles (i limit the device to 500mhz when the screen is off). The rest of the time it scales itself up to 1.4GHz without fuss and using stock voltage. Battery life is fine, best ive had for an android device.
Wow, I've taken SetCPU off but left JuiceDefender on and my battery life is fantastic. At 70% after slightly heavier than normal use (used for listening to music for a couple of hours this morning) and been off charge for 8.5 hours.
SetCPU seems counterproductive on SGS2

I did set ondemand which is a little more reactive and slightly smoother.
Though System Tuner is less cpu-consuming and much more useful on the SGS2. No need for all those complicated settings from setCPU. Only changing governor and changing frequencies on standby are useful.

Juice Defender uses as much battery as it saves this is fact, i have SepCPU set to 200 Min - 800 Max - On demand and have Juice Defender Ultimate and i thought it was great but it was recommended to me that i could save more battery by not using this, initially i was skeptical but tried it and i was astonished at the results, my battery life improved by 9 hours (i carried out a test with JD and without)
Anyone who says SetCPU uses up loads of battery is talking nonsense,it actually saves battery if configured correctly.
I am using Check Rom with set CPU I have it 1.2ghz max and 200. Using conservative governer. I been off charge for 15hrs, however I am using light usage I am on 72% screen on has been 5h 25m at time of writing. Not yet calibrated the battery.

What are the settings are you using for the setcpu program in your S2?? Did you remove the Juice defender application?
Hey, back again on a question about overclock an HTC Thunderbolt rooted with CM7 and Tiamat kernel. Anyways, I can overclock it to 1.9ghz pretty stable and suprisingly good battery life ( believe it or not ), get's kind of hot when charging though about 107 farenheit and 99 on daily use w/o it being plugged in. I was trying to get it to reach 2.0ghz, I know some of you will say its not that big of a jump from 1.9 to 2.0 but that's not the point, I am using SetCPU and Incredicontrol, and I just can't seem to keep it stable because I set it 2.0ghz and put the SVS volt in Incredicontrol to the high which is 1550 If I remember correctly, It's pretty stable but as soon as I press the lock button it freezes up and I have to take battery in/out. Any suggestions ? Thanks.
I'm not the most brilliant when it comes to overclocking (Having similar problems), but you have to keep in mind that 2GHz is double your stock clock speed, so yes, that is a big push. My recommendation is to find a low-voltage kernel that has Smartass V2 and try again.
Hmm wel l i do have smartass v2 but using smartass v1 with 1.9ghz overclocked no problems yet maybe il just stay at 1.9 but then again ill keep trying 2ghz until i get bored lol

...or cook your device. At the voltages you describe, I can all but promise you that you're slowly killing guy your phone. You're talking about a 5% gain in clock for a performance gain of less than 2%. Your phone probably isn't stable at all at 2ghz. Smartass ramps up to policy max at screen on, unless you change it, and it probably locks before the display even comes on. If you like your phone, stop. The return you get probably won't even do 1.9ghz, so count yourself lucky at that. Mine won't run that fast.

What is a safe voltage for 1.9ghz? I think right now it's at 1300-1450 I forgot, SVS(I don't know what the SVS is, just says on top of Incredicontrol). It's very stable and the phone doesn't even run hot, no random reboots or anything like that, but since you said the voltage thing I am worry now, can you explain some more? With my overclock right now which is as I said 1.9ghz, Am I still killing my phone? My battery life is pretty good except when watching videos, goes down very fast but other than that it's good. Btw what are good temps for my phone?

That kind of voltage tends to stress the silicone. If 1450 is your top limit, that's not too bad, but I probably wouldn't venture past that. Your governor is keeping it from running at that speed most of the time. Most of the heat you feel the phone give off is the battery. You really don't feel much of the heat from the CPU. Too much voltage is going to cook your CPU well before it begins to show temperatures on the battery sensor. As far as temps go, pretty much anything under 135F is ok. The battery will be the first thing to fail as temperatures rise. The SoC can tolerate much more. SVS just stands for Static Voltage Scaling, as opposed to HAVS, Hybrid Adaptive Voltage Scaling, which I don't think any Tbolt kernels support.
I don't get the purpose of that level of overclocking. My phone is snappy smooth and basically SAFE at 1.15 or 1.2

The core is designed to run at 1.5ghz (though the caches and memory arent fabbed to, really) so running at 1.5 or 1.6 isn't a big deal. More than that and you're really challenging it.
I have my SGP5 overclocked to 1.5ghz at the moment via Tegrak. Everything is running smoothly but the spot on the back where the CPU is gets warm to the touch. Not hot or anything, but obviously warm.
Before I had it overclocked to 1.45ghz and it stayed a lot cooler, but to get to 1.5 I had to bump the core voltage to 1.35v. I also have the up-threshold set to 35% so it spends a good amount of time at max speed.
Since these things don't have CPU temp monitoring, how do you tell when it's too hot? My battery temp never goes much over 80*F, so that doesn't seem like a good indicator of anything.
Sitting here playing music with Mufin my IR temp gun reads a max of 100*F on the back of the case over the CPU. Battery temp is reading 77*. Is that too warm? How much of a temp differential can there be between the outside of the case and the CPU itself?
I'm no noob to overclocking PCs, but this is my first Android device so I don't really know it's limits as clearly.
Any help would be mucho appreciated!
DISCLAIMER - anything within this thread has the potential to do permanent damage.. I haven't had any issues yet but will not be held responsible for any damage!
So I just pulled the back cover off it. Running the same program for 10-15mins the CPU never exceeded 82.5*F which is well within safe limits imo.
I guess that goes to show how poor the cooling is in one of these things with the back cover on. I'm going to keep running 1.5ghz and report any issues. The difference in smoothness between 1.4 and 1.5ghz is pretty dramatic.. web browsing is very very smooth now. I probably won't be going any higher than 1.5, but for now it seems safe.

Just tried your profile, and I have to say it works fantastic! The web browsing really is super fast.
Is there any major danger at this clock speed with On-Demand on? I mean, it'll only use 1.5GHz if it needs it right?

Ondemand from my understanding, scales processor speed using the values in the up/down (I believe System Tuner refers to down as "powersave bias") threshold. From my experience it's the best governor to use as far as customizing it easily and getting it to respond well.
Whatever you set the up-threshold to, when CPU load exceeds that value it bumps the speed up to the next "level" and ending in full speed. Then when CPU load falls below the down-threshold, it scales it back down to the next lowest level, so on and so-forth. You can also adjust the sampling rate too - lower frequency means it checks the CPU load more frequently and essentially makes the governor more responsive.
When I set mine to 35%, almost any program aside from stuff sitting almost completely idle will trip the CPU to hit 1.5ghz. This makes everything real responsive and may use more battery.. but I prefer having a more responsive device. You can also adjust the up-threshold to a higher number to try to lower temps and extend battery life. You can really play around with it to suit your needs, there's not really anything to screw up there.
There shouldn't be any danger using it with the ondemand.. but since I haven't tested this for more than a few days right now just keep an eye on temps (especially while playing games) and watch out for any "stuttering" out of the blue. Mine gets warm but nothing excessive. You'll be able to feel it on the back between the speakers.
I have to say though, even running such a high clock speed I'm not really seeing any negative effect on battery life so far.
Lemme know how yours goes!
How can it not have any risks? When the heat is too much somethig will explode wouldn't it?
No just kidding, but seriously. There is a risk of overheating a hardware and 'destroying' it, there should be!

Well of course there's always some risk in overclocking! Especially when you don't know what you're doing.
As far as using one governor or another though.. when it comes down to it there shouldn't be a huge difference.

I use SetCPU for root, but i don't see an option for more than 1200 mhz. How can I get it to 1500?
