How do I undervolt my GS2? Do I use SetCPU?
I'm currently using Gideons script. Works awesome. Look it up in the development section.

Do NOT use SetCPU. It keeps the 2nd core constantly on which equals terrible battery. Use FauxClock or Gideons script. I recommend -75 mV
Thanks for the help
Is that true about SetCPU? Or is it an old wives tale......? You decide.

I'm using set CPU with no issues and I get great battery life. Less then 1% hour drain with screen off.

So I have noticed lately since eco5 after I root and install a rom don't matter if I'm CWM3 or2.5 it gets really hot when I'm using data and while its on the charger.. and if its off the charger it still gets warmer than usual maybe its just me but any ideas? When I'm not rooted and am just stock eco5 it don't get hot at all :\ I'm lost here and could this cause damage?
(Sorry for the bad puncuation and grammer)

I should say also my set cpu its at on demad. 1ghz being my highest setting. 100mhz lowest I'm on syndicate 1.1.0 with vision kernel.

That's your problem, not all phones can handle scaling from 100mhz minimum, switch it to 200mhz and try it for a few hours.
Ok ill try that. Let you know ina few hours how it works ok thank you

Seems like all the kernels I've looked at require either some proprietary app or scripts to set the voltage levels.
Are there any kernels for the T989 that support using ordinary programs such as SetCPU for undervolting?
I'm not aware of any. I've used set CPU with every kernel I've ever ran since my vibrant days. I've never seen.the option to undervolt.

I use fauxclock. For undervolting.

im using Cm7.2 by marciin its good but i have a problem when im surfing via mobile data or playing games my phones heats up to 45 degrees to 50 degrees Celsius, ive done no tweaking to the phone, is the problem coming from the rom itself? or it has to do with my governor? im using "on demand" as its the default on the rom
It is caused by your governor. Try using smartassv2 instead.

use smartassv2
thanks, I changed my governor, and will observed if the heat will drop...

I'm looking for a good app that shows mainly CPU speed, but other starts as well. I have 0 dollars so it needs to be a free one.
Thanks in advance guys. =)

System tuner or CPU spy

I replied to you in the CleanROM thread. I don't know what other stats you need to see, but BetterBatteryStats is free on XDA. It's a required app for anybody trying to maximize battery life and the last several versions have included CPU stats.
I just want to see the ghz of it in real time.

So I noticed this switch in the submenu of Settings -> Battery
Quad Core Control
It says turning this on can help to extend the battery life, but what does it do exactly?
Also, when I did the tests on Antutu, there were no significant difference between having it on or off.
Anyone knows? Thanks in advance

Quad core control is a built in governor controller that LG decided to let us have. When turned on it pretty much changes the Governor to either "Powersave" or "Interactive." When it's off the Governor is either "Ondemand" or "Performance."
Right. And I am not 100% sure but I thought it also controls on how many cores it uses.

So it is not like the CPU control found on S3/S4/Note2 which undervolts the cpu and save energy that way?
Hmm. Is there a way to undervolt the cpu without rooting?
