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.

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.

Hi people. Im new to forums in general so try to use small words lol.
Can someone explain whats the reason behind overclocking a phone?? Ive underclocked my galaxy s down to 800mhz to save battery and you only notice when i have a few apps running which i never do anyway. Im not dissing anyone who does, id just like to know.
If theres a guide covering it ive missed please post it and ill read up

Unfortunately it is impossible поницить frequency of the processor
Speed increase.
It is useful for applications the require more grunt.
If you want to understand it use psx4droid to play a game at 1.2GHz then at 800MHz

I like everything to be snappy on my phone. Overclocking my desire from 1ghz to 1.25 makes it cruise!
I think the SGS is fast enough and you can play all the games available without lags. So overclocking is just for fun, but in normal use you don't see any difference.
how fast do you want your phone?
I overclock to 1.3ghz on my epic 4g when I use emulators and when I am not far from a charger but other than that I generally scale down to 800mhz

I have the HTC Aria, a little 3.2" Android powerhouse, dev-friendly device severely throttled by it's 600mHz processor. So I overclock it, and this little beast lives up to it's potential. It's like having a superphone in a small size. That's why overclock.

Got my Nexus One @ 1113, but really it's just force of habit. Trying to eke out a little extra performance and all that. Can't say i've noticed any difference though!
Overclocking my ZTE Blade to 729mhz (600mhz stock) can play most of HD games (...Gameloft's especially) without lagging......
I think overclocking is only for gaming purposes ... ♫

I have a feeling most phone overclockers are getting a placebo effect.
If you were to hand them a phone and tell them it was 800mhz, they'd feel like it was slower than if you handed the same phone (unchanged) and tell them it was 1.2ghz.
Mobile phone companies configure thier devices for maximum age. However overclockers push limits beyond stock. With right procedures, you get upto 50% speed boost resulting stunning output. Just your cell phone will die early :/. But not that soon. I am using DHD. Overclocked to 1.53ghz ( stock 1024mhz ). Rest, you can reckon.

Ive upgraded to the S3 gave my son my ns4g. He plays games on it and it keeps freezing up. Running rasbean. With matrix. Tried CM10 stable too.
Any suggestions on a rom and kernel?
Sent from my SPH-L710 using xda app-developers app
It is subjective to the game you (your son) are trying to play. Apart from that, check the CPU frequencies and use a bit of overclocked frequency. Also, try to shift the Governor
He played them on his evo4g I guess ill switch it back to that.

try jellyshot rom with marmite kernel.you probably won't have any issues for games destinated for nexus s.i play gameloft games with severe demands and have no lags or forced closures.
Like others said previously, a little overclock can go a long way. Just be careful not to overdo it!
So I have the US version and I've had it for a while (about a month) and I'm really disappointed with the performance. Scroll lags, the notification shade pulls down smoother on a galaxy player (that has less than 500mb of ram and is single core) and the 3d gaming performance is laggy. Like GTA3 should be able to run on max settings! Just disappointed and expected more.

OK? Why post this? Why not just get a new phone? Have you tried any other ROMs?

I played Tactics Ogre on my phone and Dead Trigger with no problems. Plus with most ROMs I don't encounter the same lag you have experience.
Maybe Powersave mode is on...

Sorry, the rest got cut out for some reason. I was asking if anyone else had this problem.
And a new phone is not an option. My family is on forclosure on the house right now so I might just cancel my data plan and use this as like an iPod.

Idk man, I've not had much lag at all. I've been rooted since the day I got it of course, so I've been running custom ROMs for a while.

Try flashing Cyanogen Mod from the original android section. General ui is much snappier and it doesn't have game lag like all the 4.1.2 TW ROMs.
Samsung really dropped the ball with the 4.1.2 updates. A phone this powerful should not lag playing temple run.

I get some lag while playing ingress and minecraft. Kinda annoying but it's better than my old phone and I hope my next is better than this one.

Are you running it stock? Phone runs great with custom stock ROMs & Kernals, but everyone has their own opinions. The games i've played ive not have any lag, but i'm running a custom kernal and ROM. That probably has is the difference, but i'm not overclocked.
well there's only two things that are certain in this world.... no tech device is ever perfect and taxes always increase.
If you expect anything different you will always be disappointed.
That being said, I had ANdroid phones since the HTC Eris and they keep improving. S3 is really nice, maybe the best of this generation, but its not perfect.
Lots of people are looking for infinite gaming speed + infinite battery life... well the two don't go together. There are always trade-off. speed vs. power, vs. size, vs. cost.
Oh and by the way, multi-core is mostly a marketing gimmick. The GPU does most of the graphics work and most apps are not multi-threaded, so a fast single core beats a slower multi-core every time. It's cheaper to make a slow multi-core processor than to make a faster single core.
I also noticed lag on the device which i put off was caused by Touch Wiz. I confirmed this when i finally rooted and started trying different ROMs.
The lag is there in all TW ROM's for me; however if you really want to stick with TW, the smoothest running TW ROM I've tried so far is Goodness. That is what i'm currently using. I don't experience lag during gaming or Apps though even with touch wiz... so might be just your phone.
However, if you can do without touchwiz, the AOSP ROMs are like butter and i experience no lag at all. At least the 4.2.2 ROMS. I've tried Liquidsmooth, paranoid android, Pac-man and Chameleon.
Crazy I'm 100 % stock and my phone runs awesome! I don't do much gaming so I can't chime in on that but I don't have lag at all like you describe. Do you have a live wallpaper installed??

I've tried a lot of the TW based ROM, Synergy, Hyperdrive , others and all the well developed one's run great for me. I don't see any lag. I also tried CM10 and no noticeable difference, I think a lot of the comment are caused by placebo effec, some people just hate OEM stufft. Also people will load up their home screens with 3000 widgets and say wow this phone / rom sucks, LOL m Then they load some new ROM with no widgets yet and go, wow this is really smooth....... until they load 3000 widgets and it sucks again. Hey , there really is a limit to performance on any phone.
Hey! I just purchased two 2600mAh batteries for my S4 along with a Samsung Spare battery charger. Now, my phone is rooted and is running a custom Rom and kernel. I am using Ktoonsez KT-SGS4 TW ATT Edition. now what I'd like to know, is (since I'll have SO much battery power) what are the fastest possible Ktweaker settings that ARE STABLE AND DO NOT EXCEED 2.1Ghz? Let's turn this into a competition. Whoever can give me their best and awesome settings wins. C'mon guys, let's figure this out. I don't want conservative battery settings, I'd like some beastly processing settings that will help TouchWiz with the lag it contains. Please respond soon, you guys here at XDA are amazing.
Thanks!

And just how are you going to determine if I'm more beastly than you?
Balance is key my friend... the whole point of ktoonsez' kernel (well more like his govenor ktoonservative) is power with battery conservation. Even with 2x 2600 you need some or else you will kill both in a day. I have an anker 5600mah battery and it is possible to kill it in a day just from screen use.

Stock kernel settings (Ondemand at 1.8 GHz or something like that). Yes, you heard me, stock. Overclocking won't do much for you at all. The other thing you're changing is the governor, which simply chooses when to ramp up the clockspeed from resting state. Changing the governor isn't going to get you more FPS on something, or really even much faster load times, for the phone will ramp up to full speed when doing work or animations.
It's fun to tweak and play with this sorta stuff, but really, you're really just gonna get placebo in terms of speed, and if you try to save battery through undervolting, you'll either have rather unnecessary performance loss or instability. Also, overclocking runs the risk of burning up the phone, and possibly destroying it to where it never turns on again all for something you can barely notice.
You really wanna speed up your phone, make things load quicker, and overall make the experience faster? Get Greenify and hibernate any apps you don't actively use (you'd be amazed at how much some background apps like Facebook consume.) Go into your Developer Options and set the animation speeds to 0.5x (or even off). Use a custom launcher such as Action Launcher or Nova Launcher that will help you access your apps quicker. Get the AOSP web browser, which tends to be faster than the other browsers. Just don't go overclocking your phone acting like that 0.3 GHz of extra power usage and potential instability is making any more than a few fractions of a second in difference.

Talk about a pessimist. You must of had some issues undervolting and configuring because my ktweaker settings have TRIPLED my battery life and kept my device stable without decreasing performance at all.
