Wow! So I've been running KP kernels for a while... with the "ideal" profile" as any of the low voltage ones would cause my phone to hang/reboot. With that profile, I normally see about 2-3 hours (according to battery-eye) before my battery is drained down to 1000mAh.... after a nights charge.

I switched to "dsp" yesterday (with SR enabled) and I went about 5.5 hours this morning before hitting 1000mAh. That profile is stable for me so far... I have 27 hours on it. And I've been using the phone like normal, so the power consumption and reliability so far are great! I'll have to see how it is after a full day of usage... I normally get about 16-18 hours usage before my phone makes that sad almost-dead battery sound.
