It's time to Overclock our Phone...
DISCLAIMER: OVERCLOCK IS DANGEROUS FOR OUR PHONES
How to:
1. Now download r151 from Here
2. Put the files of r151 in the root of SD, run HARET.
3. Download SetCPU from Here and install It.
4. Now open SetCPU, And choice "Autodetect Speeds Reccomanded".
5. Allow Root.
6. Press Windows button and choice "Perflock Disabler" and "Attemp to Disable Perflock" and Check "Set on Boot".
7. Now, close the windows and OC our Phone.
My phone under USB and AC run at 825 MHz without Crash, i had tryed to run it at 864 MHz but System Crash everytime. Without USB and AC my phone run at 787 MHz. I Post 2 Images 1. = Normal Clock 2. = 825 MHz Clock.
To Made Benchmark i Use BenchmarkPi.
1. Screen Normal Clock
2. Screen 825MHz
For Other Question:
1. SetCPU
2. -r0bin-'s Post
I did it, it works perferctly !
Upscaled to 825 and min 128
Downscaled to 245 while charging and screen off
Thanks !

Tell me please, does it helps to save the battery in last releace (r163)? I`m asking becouse i try to use Master CPU, and it seems to me that it don`t helps to save energy... But I don`t use profiles, only ondemand settings from 120-600 mHz.
Thanks!
@HTCxxxx
what is the percentage priority by profile?

In Call is 100
And Screen Off 100 too.
19 Mhz does not work for me. Phone gets unusable slow and dont come back :/
Beside that, underclocking do not have a big influence on the battery consumtion.
Undervolting would be more interesting.

Why Unusable??? Yhea, Undervolting can be an Interesting Thing, but i Think if the Volting is too low phone Freeze, and if is too high cpu can have an High temperature if you're stressing cpu and phone can freeze too. But i've noted, when i use a low "screen off" profile battery consumaption is high? why? is a problem of kernel? or is nomal?

you are right,i also experienced that 19 Mhz makes phone lazy
i'm also agree about 2nd part..i read the same

you don't need to undervolt it too low,you just need to find the right voltage
try last kernel from r0bin and you will not have high battery consumption anymore
Low Mhz does not lead automaticly to low consumtion.
If you phone has something todo (update something for example) it will get the job done faster with high Mhz and is going fastert to sleep after that.
With low Mhz it takes longer and so can have higher consumtion.
On my HD2 I dont use profiles (like screen off) and it has a very low consumtion on standby/sleep.
If you set a minimum speed when screen is off a11 is not able to go to suspend, maybe
just a quick feedback on power consumption:
it never been so good with r167+drain fix without SetCPU
when I set profiles with low frequency (19 or 128Mhz) it keeps on consuming battery up to 100mA. when i switch SetCPU profiles off, i go to 9mA in suspend mode.
true story
there must be a way to setup SetCPU in a way it doesnt affect too much battery drain in suspend mode, but for the time being i just deactivated it.

yes i see some improvement, and im happy for it...
(I THINK)
Hi All,
I've understood why CPU doesn't run @ 19MHz or @ 128 MHz...
Go to /sys/acpucloclock and look acpuclk_tbl...In It there are write all frequencies CPU can Run:
245760,400000,480000,600000,768000,787200,806400,825600,844800,864000....
but no Under 245 MHz so if You use a Profile for Screen off From 19MHz to 254MHz, cpu Run everytime @ 245MHz...so there is an high consummation of energy
bye

hi
as codiak said earlier lowering CPU(underclocking) doesn't have so much impact on battery life..he also explained you why..if you want i will explain you too
explanation:run CPU at low voltage,open an app or downloading an email,etc= CPU will take time to get to the level app needs,display will stay longer while it CPU will get done the job= worse battery life
Undervolting will have impact on battery life
explanation:run same CPU clock at lower Voltage= CPU will use less power=better battery life
hope it's clear enough for you now,and if anyone else thinks i'm wrong feel free to prove me i'm wrong
P.S. Anyway i asked devs and they will lower CPU to run @ less than 245 Mhz.
Enjoy

Ok thank you very much!!!
Hi. Trying to understand SetCPU.
There are two things I don't understand. That is MAX MHZ and MIN MHz...
Have seen some screenshots that people only change the MAX MHz. Why? And why not MIN MHz?

In essence it's to let the phone run at slower speeds when it can. This helps keep the phone cool and preserve battery power.
When I used SetCPU I used to create profiles to slow the phone down (lower the MAX) progressively as the battery % got lower. I also set it to Lowest/Very low when the screen was off.
Even now on my Sensation I'm at 192/648 screen on and 182/384 screen off. Obviously YMMV, it depends if the stuff you do on the phone works well enough at the lower frequencies. If I find it too low for something I just crank it up.

Thanks man!
I am using:
Rom: Insertcoin
Kernel: Bricked 1.5
Could you give me some tips to setup the best way setcpu.
I've seen some guys mentioning setting lowest frequency to around 400 and etc. and I don't know why. Could you give me some advice on setting up the program correctly.
Hi, I personally set the lowest frequency to somewhere around the 500mhz and smaller and set the govenor to ondemand as this will only use the the speed of your kernel when its needed thus, will use less battery.
Why around 500mhz and not 194. And will 5 sec refresh on the widget drain much battery? It's now on passive because I don't want to loose battery on bull****.

I put at 500mhz because sometimes the phone may slow down on its own and I don't think that setting the refresh rate to 5sec will steal much battery because its only a small widget
Any more opinions? Would be nice
Don't set it to 500 minimum. This will lock the phone to at least 500 mhz at all times and will cause substantial battery drain.
Go with 192 minimum or the next step up.

+1 on that.
My personal settings (most of the time) are:
Screen On 192/648
Screen Off 192/384
Governer OnDemand
Sometimes I up the frequency if I need to run something heavy, not all that often though.
agreed 192 minimum is much better. if you are having issues with the phone being slow then get rid of sense...
Just wanted to say thanks to the three users above this post as I tried 192mhz and it is in fact a lot better now (please realise I've only just turned 17 and play a lot of games hence 500mhz)
I have downloaded SetCPU in my SGS2 and capped my processor to max-1200mhz and min-600mhz. Will it harm my phone if I switch to performance mode which is max & min at 1200mhz (full capacity).
Well I think it depends on the hardware. But I would never recommend to push it at the max frequency, first of all you will decrease your battery life as well as your CPU lifetime since it will produce more heat.
Obviously it can depends of how many times a day you are using your phone to that max clock. If you are experiencing spontanous reboots that means the clock is too high, if not, well.. up to you to keep it like that.
I overcloked my Hero at 710 Mhz for about 2 years (the max capacity it's 748Mhz) and my CPU suppose to run on stock at 525mhz. I can feel my phone been a little hotter compare to the original clock but it has survived until now. (finger crossed)
But seriously.... ask yourself do you REALLY need all that power from your phone?
Hello all
My Galaxy Note runs hot.
Can someone tell me, preferably in methodical order, the steps that should be followed to sort out overheating issues.
If you watch the Australian Open tennis then you will see how hot it gets here in summer at the moment!
1. Root
2. Install SetCPU
3. Set some temperature profiles so when your Note reaches a certain temperature the clock speed is automatically dropped
4. Close unused apps and stuff
5. Don't use 100% brightness
If I was you, I would use, in fact, lowest brightness when indoors, and underclock the CPU (even when it's not hot, as opposed to what vantt1 says).
I underclocked my Sensation from 1'5 Ghz to 1'0 Ghz (both cores). And boy, It's running smooth with ICS, no lag at all.
In fact, my settings are:
Min clock: 192 Mhz
Max clock 1005 Mhz (or something around that)
Governor: Ondemand
But your CPU is probably different than mine... Keep in mind that I underclocked around 30% of it's total capacity. You might want to do the same.
Also, direct sunlight causes overheating. (Might be obvious, but when the sun hits our skin, the body starts several cooling methods, so that you only start to notice the overheating around 30 minutes of direct exposure... And 30 mins of direct sunlight for a phone is a total kill, so also one more tip for when you're on the beach: cover it with clothes, or something. It will also decrease posibilities of thieves )
My Galaxy S2 doesn't really overheat when clocked at 1.4 GHz ondemand. It's the maximum safe clock for the Exynos 4210 found in the S2 and Note. The speed is there when I need it (but that's only 2% of the time) and when I don't, it's around 200-800 MHz. I have a solid aluminium case on it, so when left on the table it can go down to 25°C. In my pocket it's a bit higher at 34°C but it's acceptable. When I play GTA3 though, it can go up to 56°.

force reboot of phone isn't always overheat. the kernel also depends on how high you can overclock.
