Undervolting

---

I've noticed that my S3 gets hot quite often and am considering to undervolt my Galaxy s3.
Does undervolting interfere with the performance of the S3? I am the type of user who HATES when there are lags when you scroll through pages, homescreen, and app drawer.

Undervolting is just lowering how much voltage a given frequency uses. It doesnt effect tye performance. The only thing you need to be careful of is instability. Not all chips can undervolt the same. If you undervolt too much for your chip you will get freezes and reboots.

That is exactly right. I have two S3 phones on the FAUX Kernel .10u Version and one can under volt to 800 for min frequency and the other will not boot with these settings. Through trial and error both are stable but voltages are different.

Thanks for the reply. Could you tell me what Kernel / Governor settings and how much i should undervolt to get a stable setting?
It would be great if the performance was still there while saving battery.

I use this kernal : http://forum.xda-developers.com/show....php?t=1756776

Things to know about the kernal:
-If you are using a stock based rom use the sammy version.
-You need to reflash the kernal after any rom flash or you lose wifi/bluetooth

The kernal is already undervolted a little. If you want more you need to do some trial and error to find what works for your chip.

Thank you so much. And which app would i use to change the clockspeed and governor settings?

So that kernel will work with stock Bell rom? If i dont like the kernel, can I just reload my previous nandroid image to remove it?
