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.

Currently it's rooted, but the max cpu speed is 1026. I believe it's supposed to be 1526.
Check that you have the power saving setting off.

Usually my ram is at 500-600mb at normal usage but now after I installed antutu benchmark test from play store it keeps increasing to .9gb to 1.12gb with no usuage at all I clear ram leave it then check it out after hour or so the ram fills up and draining the battery with 10% drained I restarted the phone same thing even with uninstalling the app it is really annoying draining the battery like that and having ram at this level what do u think I should do or what is causing it.
Thanks

See it just keeps filling like that

It will remain always like that. you need not to do anything, android itself having LMK(low memory killing) and will make free whenever it needs.
So keep as it is, It's good for health.
PS : Though you want to keep free, use option limit background process in developer option in setting, don't know ultimately how much it will improve battery, but surely it will take time to open application.
Don't worry too much about RAM usage, and don't use task killers. Unlike with Windows or your usual linux distribution, android has control on which app stays in memory and which one is killed. And it is pretty good at managing this without user intervention.
As for battery life, I recommend BetterBatteryStats if you whant to know what is draining it. But by personal experience, I think you should look at apps that use background data connection, like Facebook.
Mine always sits around 1.55 - 1.65ghz lol
Edit: I just realised I wrote GHz instead of GB. *facepalm* fail on my behalf lol

Gosh there is difference between cpu and ram
Sent from my GT-N7100 using xda app-developers app
I did a factory reset and same problem still exist ram at 0.95gb - 1.12gb why. When I usually do factory reset it settles at 500-600mb now with no apps it is high as mentioned above.

I'm annoyed because it wasn't like that before and annoyed me more when I did a factory reset and found ram high as before :banghead:

Does anything not work as you think it should? Or is this just a matter of numbers? Any performance issues?
See what I'm getting at?
What's the problem?

The problem it wasn't like that and now the issue is the battery drainage with this high ram even after a factory reset.
Sent from my GT-N7100 using xda app-developers app
The battery drainage is much more likely from you constantly trying to kill all those apps, since they then have to restart again. If your phone is not slow, just don't worry about it.

Install an apo called ram booster. Works gr8

The lower the voltage, save battery?

Yes, that is the usual motivation. It is similar to driving a car low on petrol...you ask yourself "how low can it go before I run into problems...."
Some kernel-tweaking combos I know of are Perseus & Adam = STweaks / Saber & others = Trickster / Devil kernel and Devil app
Oh. Another question. In my GPU, 533mhz is 1100. The 640mhz is 1075. So its better if i use 640mhz?

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?
