So, I'm running oxygen now. I want to undervolt to save some battery life. I've looked though the oxygen settings, and found where I can set the speed of my processor, but nothing about undervolting. Now I'm pretty sure that SetCpu can do that. But can I do it with the kernel that came with oxygen or do I need to flash a separate one?

Ohhhh....... Okay. That makes sense. I thought it was another setting. Thanks for the clarification.
Strictly speaking power = voltage * current (sorry, never quite off duty 
)
But yeah, principle is right: lower voltage = lower power usage. Running the clock slower when the cpu is idle will also help with power consumption, in part just because you are clocking more slowly but also because most custom kernels will run at a lower voltage when at a lower frequency. That's why the "performance" governor is a bad idea - it will run the battery down as quickly as possible!
And on the other side, "powersave" will make the phone as unresponsive as possible.

Indeed - I went through a spell of trying various governors, and now just use OnDemand regardless.
