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??

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?
Hello Everyone!
I have a question regarding undervolting and overclocking.
I flashed ARHD 7. I am using stock Daemon Controller for virtuous_oc. I have very bad battery life atm so I tried to undervolt it a bit more. (Clocks are 122-1152MHz).
My VDD table is like this:
clock - voltage
122000 875
230400 900
307200 900
384000 925
460800 950
537600 975
614400 975
691200 1000
768000 1000
844800 1025
921600 1025
998400 1025
1075200 1025
1152000 1000
The reason I gave 1152000 only 1v is because my cpu were 75% at that clock, thatt is too much for me. Logically..i thought.. lower voltage would lover the time spent on that clock. Results: 35% at 122mhz and 50% at 1152mhz, other % are in between. But the battery life aint better.
BTW my system is superfast and stable.. no reboots or freezes nor anything.
Can someone suggests me what to do in this case? What are your VDD levels?
Thank you for your time

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

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.
