Undervolt Setcpu settings

Hey guys. i'm using Solarflare rom and it uses snowleopard kernel. What's the right settings to undervolt it? I want to extend my battery life more. I tried to change the values in the undervolt settings but the phone always hangs.

actually i want to know those settings too, my battery seems to be running out so quickly.

Actually SetCPU UV settings are different from phone to phone, you have to find your own good settings. Just start running a day with -25mV on the different speeds and see if it's stable and if so lower it another -25mV the next day etc...
And if you are running out of battery too quickly try to set a screen off profile 200-500MHz with a conservative governor. Also try to recalibrate your battery if you have not done that, that may work wonders on your phones. What kind of battery times are you getting ? Screentime ?

Like Reidar said it's different for every device. Right now I'm using Ninphetamine v2.05 and I'm UC @ 800mHz. With UV I have it at -125mV for 800mHz, 500mHz, and 200mHz with a conservative screen off profile. Been running this for a while now and it has been stable.
A quick tip, if you want to see if a new voltage is stable quickly is to set the voltage and run a stress test in setCPU. And always remember to uncheck the Set on Boot box when testing voltages or even CPU speeds.

With my GS2 i use screen off profile on demand 200Mhz with undervolt of 800mV and work very nice, only thing is a 0,5 sec lag when i unlock my phone

SetCPU Settings

I need suggestions to setup good config in SetCPU i have kyrilos rom 7.5 beta and Galaxy 3 phone of course. thanks

There is option to automatically detect optimized setting.You can create profiles and enable them.Setting speed to powersave mode while charging and while screen off saves lot of battery.You can still experiment and see what suits for you.By the way setting some extreme values might affect life of your phone so be careful.

It is strange but in setcpu on my galaxy 3 conservative mod is not working. So ichoose userspase

Try latest version it works for me.Maybe you can try rebooting phone see if it works then.

Use 400Mhz-800Mhz on demand for battery.
Go to full 1300Mhz for performance but this will drain battery

[Q] about CM 7.1 Performance Settings~

hmm, may i ask about :
CM7.1 performance settings:
CPU Settings :
Available Governors
1.hotplug
2.ondemand
3.userspace
4.performance
as i know performance is keep the CPU run at maximum. how about hotplug, ondemand(default) and userspace, which one should i select??
-----------------------------------------------------------------------------
And what the best Min CPU Frequency set ?? 300Mhz (default) or 600Mhz???
Thank you~~~~~

I leave mine set to ondemand set max to 1300 and set the min. to 600 because when I set my min. to 300 I would get the sleep of death.
So far with my min. set to 600 I have gone a full 24 hrs. with no SOD and it seems to have not had any ill effects on battery life.

if you want to know more about the specific governor options you can read the cpufreq configs, for example
https://github.com/intersectRaven/kindle-kernel/blob/master/drivers/cpufreq/Kconfig
will show you the configs for intersectRaven's kernel.
honestly until someone tests each of these on an array of frequencies it's hard to know which is actually best. obviously the previous statements regarding sod are more than valid points.

O/C Voltage Survey

Alright guys, I've had my Dinc for almost a week now, and I think I've found a pretty good set up as far as what I need goes.
I am a professional auto detailer so I have my headphones in about 8-10 hours a day. I LOVE pandora and normally if you play pandora it will kill your phone within 4 hours.
SOOOOOOOO I decided to create a little survey to see what Kernel/Rom, O/C app, Governor, Profiles/Settings, Notes, etc.
Please guys share your settings, I would love to try out everyones setups and see what really is the ULTIMATE set up for the Droid incredible
Please everyone stick to the format just so its easily understandable for everyone who isn't part of the forums or doesn't understand what everything is.
I'll start with mine
Rom - Stock Plus
Kernel - GingerTiny
O/C app - SetCPU
Governor - On Demand
Profiles/Settings - (1) Screen Off - Priority 100 - On Demand - 245 max - 128 min
(2) Battery <101% - Priority 50 - On Demand - 960 max - 128 min
Notes - I've found I can last about 10 hours streaming radio the whole time
Also, I've found that IheartRadio uses less resources than Pandora, Thus using less battery.
When I'm not streaming any music either, I have had my phone stay on the SAME percent - 66% - for 10 hours STRAIGHT and then It stayed on 65% all night when I get home, and when I woke up in the morning it was only on 60%

Rom - Touch Of Blue
Kernel - Latest GingerTiny
O/C app - No-Frills CPU Control
Governor - SmartassV2 (245 min / 998 max)
I/O Scheduler - SIO (Set with No-Frills)
Voltage Control - IncrediControl (-25v all freqs min and max)
Profiles/Settings - None, they are not recomended or needed as the kernel has a built in sleep mode.
Changing from Ondemand to almost any other governor and slightly undervolting, will greatly increase your battery life.

And not using a sense rom will add 2 to 4 hours depending on use in my experience

I'm gonna try this out today and see how it well it works with streaming music all day. The reason I've set profiles is because I feel like when I'm playing Pandora andthe screen is off, it will force it to go to the lowest voltage I have set, whereas if I don't set profiles it will play at whatever voltage feels nessecary. That's just the way I see it, if anyone can confirm or deny this let me know.
BTW nice addition to the survey, Idk why I didn't add io scheduled in the first place lol

thanks for information..this is quite interesting...i gotta try this out

The phone doesn't sleep when music is playing so then what speed is running can influence battery. If you're curious try it without any profiles and you can still use ondemand.

Rom - Inc-Deck-Gingerbread-1.3
Kernel - Incredikernel
O/C app - none (baked in ROM)
Governor - SmartassV2 (245 min / 998 max)
I/O Scheduler - default Incredikernel
Voltage Control - default Incredikernel
Profiles/Settings - None...
I do use an app called Automateit PRO which I have used to create many different custom "rules". Every rule has a "trigger" and an "action". Some of my rules are used to automatically disable (or enable) 3G, Wifi, and GPS at certain times and/or situations that are appropriate. That really helps with battery usage...and its convenient that I don't need to do the enabling and disabling manually. But streaming music would require pretty much constant data connection of one kind or another.

My custom rom setup
I'm running CyanogenMod 7.1 on my Dinc.And Go Launcher Ex With Ice Cream Sandwich 3D Van Theme overclocked with Cyan to 245min. 1036 max. So smooth an fast.

ROM-CM9a5 alpha ICS
Kernel-Incredikernel HWA beta 1
O/C-128/1075
Governor-SmartassV2
I/O-Deadline
Profile-default, screen off-data/wifi off with JuiceDefender Ultimate
Voltage Control-default
Smooth and fast. Excellent battery life as data and wifi are under JDU control.

Cpu changes maximum frequency.

Hi!
I have a D802 with cyanogenmod 10.2 .Everything is perfect except the cpu controlling. My problem is that when i set a maximum cpu frequency it wont stay there. After a couple of minute the phone override it and change it self.. I have tried setCPU , cpu adjuster and the system default settings. Do you have any suggestion. I would like to underclock my cpu because it generates lot of heat while on heavy load.
Thanks for your aswers!
Sincery,
Moqs

I am having the same issue. Have you found the solution?
