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 have very aggressive undervolt settings that work great for franco kernel m4
Stable CPU:
1344 (untouched - 1380 mV(don't use))
1228 (1250 mV)
1036 (1125 mV)
729 (975 mV)
384 (850 mV)
192 (725 mV)
Default CORE & IVA
Battery life is strong with these for me. I can forget to charge before I go to sleep with and moderate use throughout the day, wake up to ~35%.
Screen off: 384 max
Min CPU: 192
Max CPU: 1228
Governor: ondemand

pointless.
oh and op, that's not an agressive uv..

hey guys i am having a problem with my cpu control i set the min frequency at 51 mhz and max to 1500mhz but after a while it changes by it self and goes all the way to 1500 min and 1500 max! so i tryed it with the interactive option but still it goes back to 1500mhz soo i flashed the franco kernel maybe it will change but unfortunately it still goes to 1500 mhz and eats up my battery so plzz help what am i doing wrong?
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.
I have searched around and couldn't find anyone talking about undervolt the voltage of CPU for our CPU, anyone can post their values as a guideline.
=================================================================
So far I have undervolt 384Mhz to 775 from 825, and tested stability for whole night burn test, it's stable and it gives me more than an hour standby time now.
Looking forward to test other frequency including 1.7GHz, so even overclocking the phone doesn't drain extra battery
P.S. my phone stands by at 384MHz according to CPU Spy Plus

No body care about undervolting on Xperia S?
its at most by -100
Trust me, it helps with heating issued just that tiny bit

All default voltages can be reduced by 100mv
Any lower and your cpu will reboot because of a saftey feature
Too high, and your cpu will burn out (also reboot)
Undervolting - giving a cpu les voltage per clock
Can save battery, can keep cpu cooler, can save cpu life
Over volting - does the oposite
Dont neccicarily know if this helped but i explained in more detail?
