Ok, so I'm currently unhappy with my battery life. I used to underclock the CPU on my HTC Evo but im not sure how to do this on the S3 i found a guide under the I9300 for this but i need to know if it is usable for our device as well. Also, curious as to how overclocking the GPU affects battery life. Is it the same as overclocking the CPU or is there little to no change? Also i want to know the most common voltages used as well

Is it worth rooting my phone and overclocking it?
Is overclocking it really noticable in performance to say approx 1.5GHz? And is it going to kill battery? Thanks

Yes and Yes to both of your questions. There is a noticeable diffrence in performance when overclocking. But it will obviously use more battery
cant say ive noticed 1.5ghz killing my battery.. might be used a bit faster.. but u can easily offset this by lowering your clockspeed and voltage for your sleep state in addition to minimising the required voltage that 1.5ghz requires, id say my battery life is probably better overall, and i run 1.5ghz 24/7.
of course your mileage may vary depending on usage and various settings.
How hard is it to overclock it? My phone is rooted but I have no experience with overclocking.
I'm guessing it wouldn't be a wise idea?
Yeah this seems a little over my head.. thinking of buying another Xperia Play just to mod the crap out of.
Dont really wanna mess with the overlocking now I think about it incase I fry the chips and kill the phone.
At 1.4 and 1.5ghz its quite safe.
To chill out the battery put some screen off underclocking like at Real low with but not the least
1. 4 ghz scaling interactiveX I get 252/282 MS, thats pretty fast with nitro lag Nullifier too

i currently overclocking my play to 1.6ghz and it runs fine.. games and apps run a lot more quicker
i'm quite interested in overclocking.. been thinking about it for the last months..
but i don't know, 1GHz is quite enough for me.. im not experiencing any slow down..
Well with 1.5Ghz then, you'll be amazed!

Uaed same but not recommended, when you see problems cool it
I used the XDA App to post this, what did you use?
Using phone now but mostly use the pc

I don't really know much about overclocking but it is it worth it? And how do I do it?

Well its really a matter of taste. Overclocking makes the phone a bit snapier and makes large games a bit quicker, but it also eats away at your battery faster. In my opinion overclocking is not worth it based on the small performance boost and larger battery drain. I actually under clock and undervolt to get max battery life with little or no hit to performance.
To over/under clock/volt you need to be rooted and install a kernel that supports the features and is compatible with your type of rom. From there you can use scripts or one of several apps on the market to change the values to your liking.

It makes your CPU run faster and things MAY be smoother for you. Is it worth it? Depends on how concerned for stability you are. Things could be more unstable for a possibly unnoticeable performance gain. This is coming from someone who enabled overclocking in his kernels.
If you think it's still worth it, you'd need to flash an appropriate custom kernel for the ROM you're using and install an app such as nofrills or incredicontrol or setcpu or system tuner (to name a few) to activate overclocking.
Hi,
we also talk about CPU/GPU undervolt but i never heard someone who tried to undervolt the memory RAM/ROM ? In order to increase battery life.
I'm afraid of triying because no one tried yet, isn't ?
Majority of power goes to cpu and gpu and display. So there is no point on undervolting memory.

Hi
Are you sure? If you look at Stweak example for Cpu at 800mhz you have about 1015mv and memory get about 1000mv so it's around the same volt. I conclud that memory drain some battery ??
Thanks
You can undervolt memory, just take a look at the Memory/Internal section in STweaks.
You can but you will have hard time figuring out stable values

Ok thanks guys.
Did anyone tried to do this? ??
I recently flashed the KT747 for a super fast 2.1mHz CPU overclock. But then after flashing I realized it doesn't overclock the GPU that much.
Are there any kernels that can overclock the GPU to about 700mHz?
-Thanks for any help!
Sorry for CyanogenMod 10.1 (d2att) nightly ROM.
Does the new SiyahKernel work with the ATT Galaxy S3 running CM10.1 nightly?
Ah stupid me I meant 2.1ghz or 2106mHz CPU overclock.
I don't think any kernels do GPU OC, because it has shown to cause more problems than it is worth. That's just what I remember KT saying.

Most custom kernels if not all already have GPU OCd to 450mhz
Over clocking the GPU on a GS3 is not needed and even with it over clocked, you wouldn't tell the difference. It also leads to issues and battery drainage.
The S3 doesn't need OC at all 1.2Gz with 2Gz of ram leaves no place for lag.

Then how come when I play high quality games they lag so much on all qualities.

I haven't had any lag whatsoever at any point that I've had my S3. Try reflashing your rom and completely wiping. Also try a different kernel and kernel settings.
This phone shouldn't lag at all. Maybe a little on TouchWiz but never on AOSP

My s3 lags at 2.1 GHz too. Try it at 1.6 or 1.7 GHz or change governor settings to a faster ramp up one.
Anyone with knowledge of any of the settings on kernels and what they do our mean I would love some help so I can further understand what to tweak and what the limitations are. I bought faux clock, probably shouldn't have since I'm cluelessv to what I should change because I get reboots undervolting too much or over clocking. Mpdecision I have no clue about. Noop/row/zen ect ect no clue. Thanks anyone. I'm on bioshock 2.0 and want to try and max my battery life.

I've found that undervolting by more than 50mV doesn't agree with my phone. At -50mV I do notice that my phone runs cooler, haven't done enough tests to see the difference in battery life though.
Also trying to set up a performance setting or wondering if that would even help with the streaming of movies to my ps3 through dlna file sharing. Thought overclocking would help. No use vi just can't figure it out. Any ideas on that issue?

I can't think if any reason for using the performance governor. That causes your cpu to run at max frequency all the time and would be terrible for your battery. Would also cause your phone to get verrrry hot. For things that require good performance you're best off using on demand. Overclocking could help i guess but I've never had the need to overclock... Then again I've never done what you're trying to do. Can't even imagine the need to overclock a quad core phone clocked at 1.9GHz
