You will need a custom kernel to undervolt .

As sfo stated above, just ask what custom kernel most people in the CleanROM thread are using and flash it with CWM.

I'm using Jelly Beans B8 ROM which already includes a custom kernel (Lean Kernel), and used SetCPU to adjust my speeds to a minimum of 350 and a maximum of 1350, ondemand. Already seeing a significant power increase without even touching my voltages.

I had someone install for me. How do I know if I have a custom kernal? It is quite possible since I told him I wanted to get better battery life and undervolt.

That's pretty good, and while my screen time obviously isn't as high in my example, here's a screen shot of my device from this weekend, running Scott's CleanROM and stock kernel... I've been using Android long enough to understand the value of custom kernel, but for me, I haven't seen a reason to switch with this device...

Your battery life is great. If you want more juice a larger battery would kickass with your current stats/ROM.

Under about phone what does it say for kernel? That would go a long way towards helping you

kernel version is
3.0.57 lean kernal-vzw_jb_1.4.1

 

[anon(94115)]

Well then you should be able to underfoot it without issue. That is the same kernel as discussed above

[jaybro0813]

what is the best method

 

[anon(94115)]

I don't under volt at all because it can decrease stability, and this phone doesn't need it.

Check the lean kernel thread over on xda for tips. I suppose that is the place to start
