hello guys.
i just want to ask this very simple question, what MAX lowest freq i set on the G2? stock at 2.3ghz. can i set it at 1.5ghz? will it battery life?
thanks
Yes you can adjust cpu but you should have root. If you have root then use setcpu

thanks man! yes i have root, and i already set my Freq at 1.7ghz. so, will it somehow increase battery life? or battery will be the same?
thanks
Not that much if you do a lot yes but if you use it moderately it will be useless

Create different profiles in setcpu . I had made a profile in which when i yurn off the screen the cpu comes to 252mhz(maximum) which saves battery

So I was trying to mess around with CPU profiles and I noticed that the low end of the CPU is clocked at 1GHz. If I lower it with Rom Toolbox, it just goes right back up after I leave the menu. the profiles won't stick, governors don't make a difference, and I'm a little confused.
Can someone shed some light on this for me?
I thought the lowest speed was 384 MHz? Install CPU Spy and check what it says.
It is 384MHz. The lower frequency change because of project butter that make the cpu run at a higher frequency when you touch the screen.

Dont you need a custom kernal in order to change the clock speeds?

No, we can already change it but it won't stick since it has its own frequency management.

Is this somewhat similar to perflocker in HTC devices? It had to be disabled to change any cpu settings AT ALL with the stock kernel.

You're right. I guess it just has its own profile to set at 1GHz when the screen is on, because the CPU Spy showed it in Deep Sleep/384Mhz for the majority of the night.

Hello guys,
I'm here to ask for all of your opinions about the cpu Profiles, frequencies and governor.
For screen on I'm currently using 1200mHz on performance, I would like to know if it would save more battery by using on demand governor.
Some months ago I had a discussion with few xda members about this subject. But that was on aurora v4. Now I'm currently on v5 u17. Let me know your opinion. Thanks

To be honest, I've never experienced any benefits of setting cpu profiles for screen on, screen off etc. Your phone will work much more smoothly if you stick as close to the defaults as possible.
I don't use profiles. My min is 245 and max 1200, using on demand governor.
For a while I experimented with profiles, and had bad lag when unlocking the phone, and terrible battery use when screen on.
Independent of profiles, your governor will put your phone into deep sleep when the screen is off anyway.
Do a search for "race to idle" this explains in more detail the benefits of using ondemand as opposed to other governors in terms of battery use etc.
IMHO, Android as a platform would be far better served if people stuck close to the default settings and cpu profiles. Most of the time, any negligible benefits are just placebo.

So according to the race to idle running with performance governor saves battery
Sent from my U8800 using xda app-developers app
In theory yes, but if your cpu is always running at max frequency, ie even when doing nothing, then no.
I have done tests, and my battery always lasts longer using ondemand as opposed to performance, or other governors.

Use interactive/bfq that's the best in my opinion

I have nexus 7 3G 32gb with trinity kernel,stock ROM.And i have question how do i overclock GPU?
Use Trinity kernel toolbox. It has the option to set the speed of the GPU and adjust the CPU voltages

Can my GPU burn or something like that?Or high GPU frequency will cause only reboot?
I've read that the max recommended GPU speed is 484.Going much higher the battery will drain too much and will get hot. If you set the speed to high it will become unstable and usually reboot. It will reboot and rest default speeds long before it will have time to melt. Just don't use your over clock settings to be set on boot

1. easiest way, use the trinity kernel toolbox and adjust the gpu slider up or down.
2. or manually go to /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc/ with a root file explorer(like root explorer) and manually edit the variable and save it.
yes, it can get very hot if overclocking the gpu. especially when playing cpu intensive games. worst thing is youll reboot if things go haywire.
Excessive voltage and heat can easily fry a CPU/GPU and other motherboard components, so be careful.

Hello guys,
I just want to ask some cpu settings that will increase battery life,
Im contented in my tweaks , customizations but my problem only is the battery llife,,
hope you guys can help me
Thank you very much
Use battery saver pro. Adjust the battery saver meter acc. to ur wish, but remember that battery saving is directly proportional to lagging.
The higher the battery saver level, the more laggy the phone will be. Its ur choice...

Remember this will underclock your device. So dont try to run heavy games with these settings (they may lag). Alternately be an advanced user of Tasker, and you can save a lot of battery.
Hit thanks if you think this was informative.

use ondemand and noop..
i already make some reseach 2 day ago on google..
this combination is the best for battery life without decreasing in perfomance..

Just curious what everybody is setting their cpu minimum frequencies at. I am not too concerned with battery life so I was thinking of setting mine a little higher to keep everything as smooth as possible. Is there a risk to raising the minimum frequency?

I think you would benefit more from choosing another governor instead Try intellidemand or interactive := Both of these should be better than ondemand

i have mine set at 300000 so when my phone goes into deep sleep it's using little cpu power, but i also have interactive governor so that when i turn the screen on there's no delay and the kernel and cpu have what they need to be snappy.
this thread tells you all you need to know about governors and i/o schedulers.
