Setcpu?

Anyone here try setcpu on your Galaxy S 4G?
I'm sure there is some "new and improved software" reason to not need it, but I figured I would try it to see if I could improve battery life in some way.
I'm still tinkering with the settings, but I think I have noticed a slight improvement. If you try it, don't set your screen-off speed to any lower than 400mhz. If you do your phone will slow to an unimaginable crawl, sometimes only to be recovered from with a reboot/battery pull.

You can use it but until there are custom kernels that allow you to underclock or overclock its gonna be a lost cause imo. At this point its only good for changing governors and possibly screen off profiles and things like that

It already hauls once I removed bloatware, my system is pretty "bare bone" now, and it's FAASSSTTT.
That being said, one of the main reasons I upgraded to this phone from my modded HTC HD2 was the battery life was horrible on that phone (comparible to an evo 4g as per many side by side tests with a friend who had a new one).
Battery on this phone is GARBAGE, basically the SAME battery life, maybe only slightly better if at all....
I thought technology was supposed to be improving. I mean I abuse the phone, It's my sole entertainment while I'm at work (I work at a call center). I'm doing things on it 24/7.
But I figured it would perform better than a non-native android phone, modded to run android, that's two years old.. (htc hd2)

I have been using an app called tegrak overclock. it seems to work great for me.

You can overclock without overclock kernel?

I just use setcpu to disable auto scaling..

TegraK seems to work. It's an "on demand, on the fly" patch that isn't persistent.
I see improvements in benchmarks and reads/writes. So, it seems to work. Every time you reboot though, you have to reset it.

Overclock Kernel Question

So I found a kernel on the Fascinate forums that was built off of our EC10 froyo source that was from nemesis2all and I saw that he had added the ability to overclock and undervolt from within the ROM so I installed it just trying (backed up of course) and found that it does indeed work.
I then got the Voltage control app from the market and started playing around doing Quadrant scores throughout after each change. I found that at 1200 mhz I was getting 1600s instead of 1400s and the phone ran great. But when I tried 1400 mhz the phone froze up and restarted while doing the CPU section of the Quadrant test so I reverted back.
My question is, what would be safe to stay at for general use?
Second question, how do you use the voltage app to undervolt I see the settings but I don't know what to set them too.
Here is the link to the kernel

1200 has proven to be the most stable overclock, any higher and it will freeze up eventually.
With voltage control, the way it works is that you set the max clock and then it will give you increments that the phone will automatically clock to within the guidelines you give it. Then for each increment you can set the voltage it will use. Just look around and experiment with voltages, see how low you can go without having issues and never set it to apply at boot unless you know that's what you want, other than that go crazy and a reboot will fix it if you have a problem.
I recommend keeping setCPU installed along with it, that way you can still force it to underclock or overclock or whatever. It all depends on how much you use the phone and what for.

I've been running overclocked at 1.3 and undervolted at least 50 for a couple days now. Only one issue and I'm not even sure it was related as it janet happened again. I posted my settings in the otb thread if you're curious.

H'm, I tried going up to 1.3 and it would freeze up after 5 or 10 minutes every time.
Like I said, 1.2 is the only one that has proven to be safe for everybody... not each phone is exactly the same and if akellars CPU has a soldering that is done a little bit different than mine, it might allow him to clock a little higher. who knows
Sent from my MIUI SCH-i500

I've been running it for a week @ 1400 -25 undervolted and haven't had any issues. The new 1.6 gives me trouble. I don't think there's enough overvolting in that one to make it stable for pretty much anyone. I use the 1400, 800, 400, 200 steps all undervolted @50 except 1400 which as mentioned is -25. Battery life is good because during sleep it doesnt really hit the high end and by not having the other steps its snappy when in use. Fastest this phone has been by far. I don't use setcpu because I think it and the voltage app conflict. That was nemisis's instruction to install it.

Yup I'm just lucky 1.4 worked for me too but I didn't see much of a performance difference so I didn't see the need to stress the cpu out anymore than I already was. battery life had been awesome for me with my setup as well.

[Q] SetCpu help!!

"Third -(Root Needed) Set CPU. Have had this on my G1 and N1 and it does nothing but save battery. I currently have it set on 216 - 1000 for when the screen is on and the only profile i have is for when the screen is off and it is at 216-216.
(Alternative) Pimp My CPU. I now am using this for my G2x because I am running custom kernal. Personally I like Set CPU better, but do to the fact that Set CPU can't get past 1000 MHz makes it kinda useless for the G2x Tegra 2. "
This is for the thread "Twenty Hour Of Battery Life" When he says he currently has it set on 216-1000, is he using the "Pimp My CPU"? Also where is that set at exactly? Is it set on the "Main-Scaling Driver" When you open up SetCpu? My "Scaling" is greyed out, I can not set it to "OnDemand" or anything, and yes my phone is rooted, it was the first step in that thread. Both Min, and Max go from 122, 128,245, and 528mHZ, so I am confused on this 216-1000? Also When I go to create a profile, and choose "Screen Off", I have the same issue as above, 216-216? What is that??? Be specific, and I am not a stranger to rooting, etc, so help me out, so I can on to the next step and install "Battery Calabration"

Haha What typed is pretty simple to understand. I have the app SetCpu and when you open up, you are at the "Main" Tab, "Scaling" is greyed/blacked out, I can not set it to On Demand or Conservative. My phone is rooted, and SetCpu has Root Access.
Now how come scaling is disabled? Also, when the person who created the thread "Twenty Hour Battery Life" said he currently has it set to 216-1000, what does that mean? how do I set it to that? He also mentioned that he created profile for when the screen is off, and set it to "216-216", I do not understand what that means, and how to set it like that? I created a profile "Screen Off", but I am stuck at how to put it to "216-216"?

Ummmm. Iirc set CPU does not work on the g2x yet. Pimp my CPU should.

Setcpu works fine he needs a custom kernel.. Like mordic or faux..
Sent from my LG-P999 using XDA Premium App

On my Nexus One here the only thing I have Setcpu do is when the screen is off it goes to min245 max 384. While using your phone Android regulates your processing power based off of what it needs. While Android does that when the phone sleeps I don't want it going above 384. With my Nexus One I usually get around 18hours + of battery life w/ medium usage. I didn't have my G2x long enough to try out Setcpu but IMO only have setcpu regulate your sleepmode

Why do people keep saying this? I guess the author of the app is lying when he says it is compatible and all the people running it successfully are lying also.
SetCpu supports Terga 2 starting with version 2.1.1a
I have no idea where you are getting you info, but you are wrong.

I recall reading it here on xda. But that was over a week ago. Like I said iirc does not mean I'm 100% right.

SetCPU does work with the tegra2 but I am not sure if it is playing nice with the custom kernels made by Faux and Morfic, that is why everyone is using Pimp My CPU

SetCPU works for scaling but not overclocking.
A great free app that DOES work with both of those kernels is CPU Master - find it on the market.

Thanks for clearing that up. I knew something wasn't right with set CPU onthis phone

What are your settings for CPU Master for the Tmobile G2X? I want to get 20+hours at least, I am using Battery Calabaration from the Market and I charged the phone to 100%, opened up the app which required root access, tapped battery calaberate, then unplugged it, that was at 130 or 1:40, it is now 5:35pm, and it is at 76%, not lasting at all

That's great battery life considering its a dual core tegra 2 phone which will always suck alot of battery juice . If you want a 20+ hour device then get a blackberry.
Android phones are known battery leeches. Look into a portable battery charger

Setcpu does support tegra in G2X but currently does not support oc'ing. The scaling is greyed out on mine to but doesn't affect it sd i have seen.
So if your looking for settings use these for setcpu
Profile battery < 25%
Max 500
Min lowest
Reason: save battery amd extend phone usage
Profile sceen off
Max 1ghz
Min lowest
Reason: will drop to 216 if not using and is in idle but will jumo up if processing power is needed
Profile general (main screen)
Max 1ghz
Min 1ghz
Reason: makes cpu run full steam when using

[Q] dragon ota kernel 1.1.1 (i think)

i never used custom kernels before but overclocking to 1.5ghz is awesome. one downfall, phone gets super hot and my phone restarts. i've heard of undervolting but i have no clue on how to set it using setcpu. i've heard 1.5ghz to be something like -100mv but do i set -100mv to all of the frequencies?

What do you need the phone to do if you want it to be constantly at 1.5ghz?
You can try using Faux's or Trinity kernel. Both have versions that are already UV'd upon flash. Although some chips can't handle UV. Also, I believe you have to use a different app to control your voltage.

When i play games or watch movies i set it up to 1.5ghz and since school is out and no job... im kinda on my phone for a few hours. Also, i tend to forget to turn it down.
Oh yea my bad, its cpu master. I tried -100mv to all frequencies and it'll work for like a minute then it'll freeze and have to pull out the batt.
I'll check out those other kernels but this one has really fast boot. Although, which of the other kernels gets updated the most?

Faux boots up in less than 30 seconds for me so give that a shot. Both Faux and Trinity get's updated very often. So you can't go wrong with either.

I play games like dead space and Nova at 1.2 and have no lag whatsoever, basically they only time overclocking to 1.5 does anything is when you're running some type of performance test.

aaahh yea im starting to c wat u mean. keeping it 1.1 and its still good. got used to the old phones under 1ghz and single core.
oh, do guys have to links to the kernels? im trying to find it but its usually part of a rom.

Go in the development section and look for [kernel] in the titles and not ones that say [rom].

What are you overclocked to?

I guess you can consider this thread part survey and part for my knowledge so I know how far I can push this phone. I am at 1728MHz max with the interactive governor and cfq scheduler. Not sure if I'm going to do any undervolting, I can get through the day with about 40% remaining, and I have profiles set up for low battery and such. I am running CM10 with the 747 (I think that's what its called..) kernel and can push it to 2.1GHz. Is it stable at that high of a clockspeed? I can assume it turns your pretty Galaxy S3 into a convenient portable stove
By the way, sorry if this is the wrong section.

It really depends on your phone, I had mine at 2100 and it was stable. However it can very I had,a, Droid charge that ran the 1440 no problem, had it replaced and the new one could go above 1300 without hot boots. Some phones just hold up better

Stock. I've had it clocked to 1.9. But can't tell a difference with real day to day function except for worse battery drain and phone hotter.
Sent from a SYNERGIZED GalaxySIII

I have run the KT747 AOSP kernel at 2.1 ghz for a day or more and had no noticeable increase in heat, or decrease in battery life. (lulzactive or smartass v2 with either cfq or sio scheduler, no voltage changes in KT tweaker) I also saw very little or no gain in real world performance increase, and the benchmarking apps seemed to back that up. Typically run mine at 1.809 currently. Every phone cpu is different in terms of top speed, and voltage settings. Best thing to do, is to test them and see what works best for you. These 2 links, courtesy of the Ktoonez thread, provide some great info on kernel governor and scheduler settings. Given the number of options in KT Tweaker, these helped me a great deal in terms of making changes.

I've tried 1998MHz and as you said, it didn't yield much. I think I screwed something up, because now oc settings refuse to stick (resets itself to 1512) and short/long benches are not as great.
