Why shouldn't you set it too low?
Can it cause damage? If so, what kind?

+1 this is a great App using the phone at night
That doesn't actually uv the screen though just so everyone is clear. The app is putting a filter on the screen not reducing brightness which if it was working they way you claimed it would have higher scores in quadrant. Test with your normal brightness setting first you will see that with brightness turned down you get higher scores but with this app it actually makes the scores go down which implies its actually using more voltage that takes away from the processor which is why the lower scores. So and which more voltage is not gonna help with battery life as the op was asking for.
Yea that app is funky i was wondering it could be uv like cpu is

No not that i know of lol you can only adjust brightness which will save battery also black helps conserve battery also so i would suggest you set a dark wallpaper and flash a dark theme
Screen Filter is cool but I notice if its lower than 54% on our phones, it gets annoying to look at. It does help with battery life when you're indoors, the second you take it outside you have to pop that thing right off. Helps to have a widget on the home screen.

I'm sure there is some risk to overclocking but is there significant risk of frying the CPU if constantly running at higher speeds? Like if I have it set at 600-806 most of the time?
I really dont know. However, i have been overclocked to 824mhz for about 2 months probably. Havent noticed any issues thus far.

I set mine for when the screen is off to run at the lowest clock, and I have great battery life and no issues.

Not that I have run into, but if you set your minimum at 600 your battery life will be horrible, just do 245/844 interactive. Works great.

Odd, when I did 245/245 for screen off I actually lost a lot of battery life, I turned profiles off and set my phone to 245/844 interactive and I have better battery life than ever. I figured it had something to do with overall load being higher when the cpu can't clock up. I'm pretty sure unless it's doing something big while the screen is off it stays pretty low most of the time anyway
I don't have set cpu I have just plain overclock widget and I set mine to 480/600 mhz on start and when on stand by like 140?/180. That way it saves the battery. My phones battery life is amazing now. P.s. this overclock widget is free.

Depending on which governor you're using, setting profiles and setting the clock to 245/245 certainly would effect battery life. If you're using interactive you don't set profiles. Just min/max and leave it.

Ah, I suppose that would do it. That's what I do now, after I was getting horrible battery life I just disabled profiles entirely and now I leave it at 245/864 and it works great, normally get 10-20 hours on a charge.
I feel like my interactive govenor is broken. In the past when its on and I start clicking through the setcpu tabs the cpu would move or right when I open setcpu the cpu would be higher than the min but now its always sitting at the min I set. I ran a quadrant test with interactice on and only got low 800's but then switched it to on demand and got low 1200's. What's the deal with that?
Hi all,
I've set some profiles in SetCPU but haven't noticed too much in battery life savings. I was wondering what others who are using CM 6.1 have been doing/would recommend. Should I get rid of the profiles and just have it set to on demand? Do I really need it at all with CM?
Many thanks!

How high are you overclocking?
What's your usage?
What's are your profiles?
Overclocking to 1401 on demand
I use power amp with scrobbing to last fm for probably an hour or two when not charging, while playing games that aren't to elaborate (boring stuff like sudoko) during my commute to/from work, which is probably my heaviest usage. I also do the same music set up while at work but I'm plugged in most of the time for that and volume is way down. Calls range from 30 min to an hour a day. Some intermittent web and video streaming while at home and on wifi. Typically only on wifi when at home, only when I need heavy data. Data sync is turned off when I'm not charging unless I want to sync.
I have profiles of 368/245 while sleeping, 75 priority; 738/245 when temp is 40.5 C, 60 Priority, 1401/245 when plugged and fully charged, 50; 368/245 when battery less than 10, 60; 806/245 when battery less than 40, 50 priority.
I'm thinking the fully charged one is probably redundant. Should I raise the priority on some of them?

I always set temp as the highest priority however i OC a lot higher then you. What oc kernel are you useing? This makes a huge difference some have a lot more steps which allow better power use. Pershoot is the most efficient imo right now.
Sent from my HTC Vision using XDA App
I think I'm just using the cyogen mod kernel...but I'm new at this so I am a little clueless on that part. I did set higher priority on the temp and the screen off, got rid of the charging profile. I'm at 13% battery after about 15 hours, which isn't horrible but not the 30 hours some folks have been posting.
Sent from my HTC Vision using XDA App
had to dig back to find a good thread to post this on....
so I'm really leaning toward deciding that setcpu profiles do more harm than good in terms of battery. I had profiles set for temp, screen off, charging, battery below 30, and battery below 10. its pretty clear to me now that it wasn't helping my battery. and the only time I even had it overclocked was while charging.
next I'm going to just enable only a screen off profile, and see if having setcpu monitor for less profiles makes a difference. i'm not going to overclock at all. we'll see what happens.
btw I've had a rooted android phone since the G1 so its not like I don't have experience with setcpu. seems that setcpu affects different phones in different ways. so I'm still figuring out how it is on the G2.
anyone have any thoughts on this?
The screen off profile does not work.
Just use the phone out of the box and charge when its empty

really? I hadn't heard that. is this confirmed?
though, it never seemed to make all that much sense anyway, as I wouldn'y think there would be any reason for the cpu not to remain at a low freq with the screen off
The screen off profile works for me. I just set to "ondemand". Lately I've been using "cpu tuner" instead and have noticed better battery life then with set cpu. Plus with cpu tuner you get more profile options.

To be honest, not sure if its the case for you but profiles was the cause of my battery life drain. I took off all profiles and only kept screen off. Even since I did that I get about 24 hours + of battery.

I had a similar experience. The more profiles I had enabled, the faster my battery would drain.
I am using the same setup now and have great battery life. Even with heavy usage I can make it through the entire day without needing a charge.
Running On Demand 1209/245 and screen off 245/245.
Haha this was an old thread. I'm now on CM7 nightlies and would say that in my experience I've had the best battery life running no profiles whatsoever in setcpu. I only overclock to 1017 and it's been pretty snappy still. My experience in going higher than this on CM7 has lead to issues with wake, temperature and battery drain. I personally Have no need for more than 1017.

agreed. this setcpu stuff did not help at my device. nor did it work reliant.
i am managing 1day with heavy use and a full weekend with moderate use without any "tuning".
that is enough for me.
I used setcpu for awhile, but I have been much happier using cpu tuner and "power control".
My battery life is increased by 12 to 24hrs. The key for me is really using power control to manage the screen brightness and under clocking rather than overclocking. The only time I found overclocking usedful was when playing fifa10.
Good luck

ok so i just got my GSIII and downloaded cpu gauge and cpu spy
cpu gauge shows my max cores being 1.026 each I thought this is a 1.5 dual core it should show max at 1.512.... also cpu spy shows NO activity past the 1.026 mark..
phone is fully stock i have not done anything to it yet my question is, Is the phone defective and i need to return to att?? thanks

Yea power mode, horrible feature, barely saves battery and slows phone down. Your phones cpu throttles when it needs to use its power so it saves power that way. Im on JB AOKP and with it overclocked too 1.9ghz and throttling too 197mhz I get awesome battery life. Im sitting at 35 hours on battery with 7% left with moderate use. Thats incredible!

i use the power-saving feature a lot... i get paranoid when the battery gets below 30% and i know lithium ion batteries should never be fully discharged. the phone functions surprisingly smooth at even 1000 mhz and the decrease in speed barely even unnoticeable unless you're heavily multitasking. i also have SetCPU to underclock my peak speeds even lower for certain apps, or during various charging states, or different times of the day (evenings, weekends, work hours), and overclock for more resource-intensive apps (browser, skype, games, etc.).
try undervolting your cpu as well to have the best gain in battery life. ppl often forget the voltage part of CPU especially if you are going to overclock this puppy
I'm big into getting the most speed out of all my purchases but came to the realization that underclocking my phone to 1.2Ghz (Trinity kernel/free gs3 rom/Nova Launcher) with SetCPU is just as responsive at 1.2Ghz as it is at 1.8Ghz for the most part. Not a big gamer but from the ones I've tested I noticed no lag whatsoever. Just thought I'd share for everyone addicted to benchmarking their phones for evaluating what speed they want to run with. In real world usage I'm still very happy @1.2Ghz and battery life went from wonderful to phenomenal. Best part is that with the savings I'm seeing on the battery I now feel more comfortable increasing the brightness to a more comfortable level.
I use touch wiz launcher and with it under clicked to 1.3 I start seeing noticeable lag. And battery life was not that much better. I do keep my screen at full brightness though.

Hey guys, I had my phone for no more than an hour. Rooted and flashed cm10. Phone seems to get warm like 100 degrees f. And that's not using data or WiFi.
I had stock on for a little and noticed the same thing, is my phone jacked or is this normal? I have warranty so if none of you guys experience this I'll take it in. I just don't think it's too healthy for the device...

My phone gets pretty hot sometimes too, but only during heavy usage and multitasking. If you're finding that it's heating up when you're just browsing the web or installing apps, try using another kernel. I recommend Lean Kernel with CM10

My s2 barely gets hot :/ and thats with no back cover on just a case. but the battery temps are much lower as well on the S2. usually around upper 70s to lower 80s degrees farenheit under normal load.
yeah
my phone does the same it sometimes does the same it gets hot on the bottom back part
Personally I believe it can be rom/kernel related too. Usually it doesn't get really warm for me except under load. But with the latest leak, if im using it at all, it just stays warm. When I was first using it this morn it actually got pretty hot and when charging got even hotter. I let it cool and hasn't been that hot since.

Mine use to get a lil warm too under heavy usage,until i flashed Faux kernel(<<THIS KERNEL SUPPORT UNDERVOLTING) on sonic Gs3 rom & then i used system tuner to undervolt cpu further(yes undervolt not underclock) although i am running at default clock speed with conservative & cfq settings.Since then my phone runs pretty cool even on heavy usage.I heard the default voltage are sometimes higher than what is needed which may increase phone temperature faster,My battery life is even better now than it already was on Gs3 rom, KEEP IN MIND YOU MUST RUN A CPU STRESSED TEST IN THE SET CPU APP WHEN YOU CHANGE YOUR PHONE VOLTAGE SETTING TO MAKE SURE THERE IS NO ERROR,RANDOM REBOOTS,BOOT LOOP,LAG OR JUST A LIL SLUGGISHNESS BECAUSE YOU UNDERVOLT TOO LOW & KEEP IN MIND NOT ALL CHIPS ARE CREATED EQUAL,So my settings may only be stable of my phone,you may have to take that risk & experiment around.
I attached screenshots of my personal undervolt in system tuner & also a screenshot of default voltage of I9300 variant but i figure.
check the option to use settings on boot in System tuner or you will have to keep setting it on each reboot

Well in my life of hacking phones, under/overvolting seriously reduces life of the CPU.. i dont quite feel comfortable undervolting my brand new galaxy s3. lol. Unless someone can provide scientific evidence to undervolting not causeing long term harm to my CPU.

No reason to undervolt or overclock this hardware. Overclocking became irrelevant when dual cores came out. Undervolting was never relevant. People do it because they like to play around with their hardware, which I understand, though I've always been more interested in software myself.
What are you doing when the phone gets warm?
Mine seems to get hot as the battery gets low (not even on the charger).
