I'm running 245/614 governor. I lowered max voltage by 50mV. At 245 my min is 925 and max is 950. At 614 my min is 950 and max is 1050. I lowered min voltages by 25mV once and my phone shut off and had to do a battery pull to get into recovery. How low are u guys gettin ur mins??
I know unrooted desire z devices always work at 800mhz. My device is set to 245mhz min and 1400mhz max (interactive or smartass governor). It sometimes causes my device to wake up a bit late. I wonder how long time my battery goes if I set my device at min 800 mhz and max 1200 or 1400 mhz... Did anyone try this clock speeds?

That's way too low of a min speed, just bump it up to the next (I think it's 386) and you should see noticable improvement.
I'd also suggest the ondemand gov; since it only ramps up to the top speed when needed, then drops it back down again, you should get a bit better battery life.

i read ondemand and conservative governors are od, so using interactive or smartass are better then using others. I will try min 368 mhz but am not sure if it works...
What are you trying to accomplish by messing with the clock speed? Leave it alone at default. Performance difference is NEGLIGIBLE (bottleneck is elsewhere), and all you'll accomplish is eating the battery and burning it up with excessive heat caused by excessive clock.

First of all, I would like to thank you for your comments.
People don't do anything to access root if they don't want to mess device. I am one of them and want to have a device which both has performance and visuality. You offered me to not to change clock speeds. But we know HTC Desire Z is scheduled to work at 800mhz everytime (default). My opinion is just to set minimum clock speed to 800 mhz or something like this. If my device was burn by this clock speed, it was already dead.
Today i tried this clock speed (min 614, max 1382) and during the day it didn't heat up. Moreover, 8 hours passed, i played NFS for about 1,5 hour, made some call and 30 percent of battery left. It seems this clockspeeds doesn't cause battery drain or i couldn't feel it...
EDIT: 13 hours passes, 16 percent battery left (I made minimum 30 minutes of call)
In the following settings, is the battery use equal?
CPU set to 200 MHz @ 900mV
CPU set to 100 MHz @ 900mV
Does this then mean that the first option below uses less battery?
CPU set to 200 MHz @ 900mV
CPU set to 100 MHz @ 950mV
Or is there some other aspect of the 200MHz vs 100 MHz that affects the battery outside of the mV?
I've been playing around with undervolting my Epic 4G with SetCPU and Voltage Control and have noticed that it does not crash if I force it to operate at one frequency -- apparently it is the switching from frequency to frequency at too low a voltage that crashes it. But what I'm seeing seems absurd -- I can overclock to 1200 MHz and set voltage to the 600 mV minimum and run just fine, so long as set the minimum to 1200 MHz as well.
I've run benchmarks with SetCPU and it definitely is running faster at the 1200 MHz setting. I am wondering if the 600 mV is "real" or if perhaps SetCPU and Voltage Control are misreporting what the CPU is actually running at.
I would think that half voltage would result in one quarter the power consumption, but I have not had a good opportunity to observe its battery life yet.
Having an issue with charging for the past few days. Phone dies quickly. Phone charges really slow and in CPU Spy, it's either at 1600 mhz or deep sleep. Nothing in between. I checked the clock speed and it's 200 mhz - 1600 mhz. I don't know what I'm doing wrong.

do you have the governor set to performance? do you have a profile that comands the cpu to work at 1600 mhz?
