My CPU's temp is ~ 49 degree when do nothing, but when i do something it will come to > 53 degree .
I flashed all Custom rom to find one can help my cpu temp is low but .. it still high.
This is hardware problem ?
I'm getting mid-30s when idle. I suggest trying another kernel.

Which ROM and which kernel are you using?
Also, undervolting will reduce temperatures substantially.
Im using CM9 beta-0.4.5.1-cm-9.0.0-RC0-olympus-UNOFFICIAL-signed.zip
Kernel 2.6.32.59-MB860-CM9-gf77ecf8
Jokersax
This kernel may doesnt support Voltages. Open SetCPU i not see Voltages tab.
Can u suggest me some other kernel ?
Try faux123's kernel, and then do some undervolting.
I changed to faux but when change some voltage setting then my phone hang and reboot many times. temp still so high ( i only set -50mhz). Any sugest ?
Try -25 and use profiles for screen off. Don't forget that there's a 100mV delta limit for each step. Are you overclocking your phone?
My current settings with faux123's kernel:
Screen off profile: 216 min - 456 max
Voltages:
1000 MHz - 950 mV
912 MHz - 900 mV
750 MHz - 800 mV
608 MHz - 700 mV
456 MHz - 600 mV
312 MHz - 500 mV
216 MHz - 400 mV
A note about undervolting: not every cpu is the same. You might be able to get an even lower undervolt, or you might not even be able to undervolt at all. Just make sure you uncheck "Set on Boot" until you get a 100% stable undervolt.
Edit: While you're at it, take a look at the "Time in State" info. What frequency does your phone spend most of its time at? If it spends a lot of time on higher frequencies, there's your culprit for high temps.

Which Faux kernel did you flash? You should be using the 1.0GHz kernel. If you are using that and have mild UV then you should have no heat (or battery life) issues. Also, you need to check for any apps which are causing your CPU to be continually under load when it should be at idle. This could also account for higher than normal heat.
Your phone should be able to handle -50 Hz at all frequencies, as that is a very low UV.

I flash Faux 1.0 GHz kernel (my old post) like u said. I will try all you suggest then report soon tks guys
I tried all you suggest but still automatic off (or idle cause i press power button my phone dont start ... it like my phone is hanging ) then I must off my battery to power on my phone.
The average temp around 44 degrees or higher ..
What ROM are you using, and did this problem occur on stock?
I'm using CM9 ICS
Sometime with stock rom, this problem appear. I think it from my phone's hardware. When CPU temp > 50 degree it happen.
Today,
after talk over skype,
view some webpage,
it's seem abit hot (about 45 degree).
After all, i lock screen then put to my trouser. When come to other place I open it, press power and nothing come to screen like its still running so i must off my battery to turn on again.
Flashed many rom from stock to custom but never see one can make me feel happy ). If it from hardware so poor me
Sounds like a hardware issue. Do you happen to use any type of case on your phone?
rieslav canopy
I dont use any case on my phone (sorry my bad english, "case" in your question mean protect item ? ).
I just found, when my phone is hot, it will shutdown.
Today when my battery < 15%. My phone suddenly running smoothly @@. I dont know why.
trying to find a way to help my phone run ok

Hi all!
I'm playing with setCPU and probably I found my high stable freq. to 787Mhz.
I can run quandrant till 825MHz (1300+) but it seems not very stable and sometimes freeze during normal operation.
I set 787Mhz and interactive mode on setCPU and I leave 245 as min freq.
I setup 2 profile in order to downgrade to the original 600MHz and 245 with powersave when the battery is < 20% or the temperature of the cpu is > 50.
My question are:
- Is the interactive mode the best option for our Optimus One or there's a best choice? What is the differenze of the different operating mode?
- What is the "temperature limit" of the cpu? I set 50 but my cpu start from 35 up to 39.5 during stress at the moment. Should I set 40?
- How the min freq influence the performance and the battery life? Is it good to increse the min freq (320?) too?
Many thanks and sorry for the many questions.
is set cpu stable on lg optimus one?
Can u guys share ur set CPU profile. I need profiles with great performance and less battery consumption. My profile is as followed :-
Charging AC/full 748 Max 480 min
Screen off 245 max 122 min
Performance n battery don't come together ..... I use ondemand 729/425 ... nothing different for screen off .... works really smooth n decent battery also
Sent from my LG-P500 using XDA App
But I Also need to manage my batteries...
My setup's kinda similar to yours,
480/720 ~ on demand ~ when charging/full
Otherwise 240/320 when screen is off. BTW How long does yours last?
Hey !
That's for me :
Charging/full : 729 - 245 / ondemand
Screen off : 320 - 245 / conservative
Battery < 40 : 600 - 245 / ondemand
Battery < 20 : 480 - 245 / conservative
I don't have many profiles, just 1.
245min / 748max
Battery's life is kinda good, usually I have to recharge one time a day. It's not a problem for me.

I even used battery less than profile but it slows the phone too much....
Well It also depends on which ROM you have on your phone.
Mik_os CM7 port actually EATS the battery and It runs out of juice in less than 24 hours with a normal usage. A bit better with devoid v5, but I feel like openOptimus is the best one out of the three.
I use only one profile: battery < 101% @ 729/122 smartass
great advice so i must be changing my rom as soon as andy releases his new build!
729 max 480 min smartass
I use:
Main 729 max 320 min smartass
Charging 600 max 245 min ondemand
Battery < 40% 600 max 245 min conservative
Battery < 25% 480 max 122 min conservative
I used to keep a screen lock profile at 245 max but my phone lagged while receiving calls when the screen was locked and sometimes while playing music.
I use devoid.franco and
729/480 interactive
Screen off: 600/240 ondemand
What is that of smartass? My SetCpu havent got that mode :/
have someone got a guide or something that explain each mode (ondemand, interactive...)
Using stock ROM.
Normal: 729 max, 245 min, conservative
Charging: 768 max, 245 min, ondemand
Battery < 20%: 600 max, 122 min, conservatve
Battery life greatly depends on my usage. But, generally, I come home after classes (where I use it for internet, music, games etc.) with 30-40% battery left.

i got dis man
Program for controlling CPU frequency on Android in order to increase productivity or increase battery life.
Of the features worth noting customizable profiles.
Description of modes:
* Interactive - an interactive mode, driving frequency of the CPU in real time, almost always at full productivity.
* Smartass - a regime based on Interactive. Has a more rapid decline in frequency in a simple, but also lowers the frequency to a minimum at a turned off screen.
* Conservative - operates at a very low incidence of possible CPU and increases incrementally, as needed.
* Userspace - allows you to change the frequency of the CPU, either manually or dynamically, at the discretion of the software.
* Powersave - reduces the frequency of the CPU to the lowest possible level.
* Ondemand - operates at a very low incidence of possible CPU and increases the maximum reaches values of CPU usage - 100%.
* Performance - sets the maximum frequency of the CPU, not allowed to change frequency downward.
1st : My understands
So I'm completely new on the undevolting science and don't know if I understood everything correctly... For me, undevolting the cpu means : reduce power consumption for the same speed, so we can minimize the battery drain and have the same performance at high frequencies. Am I right?
I also understood that if we UV too much, the phone will be buggy/freeze. Is there any other risk I should be aware?
2nd : My statements
I start to UV my phone tonight and now I'm quite surprised to see how low I can go : I'm running at 1200MHz / 600mV (instead of the stock 1275mV) and the phone is solid stable (I don't know if I can go slower though, I was a bit scared and decided to post this message before continuing). So how do I check setcpu applied the settings correctly? To check system stability I use setcpu's stress test for about 2mins (the short test between two settings), then about 10mins (the big test for the final seting) and finally my feelings using my phone as a daily usage. Am I doing it right?
What are the common values at the UV exercise?
3rd : Some wtf in my head
If our phones can handle a so low value (compared to the stock one), why is it so high by default? I understand that, for stability and because every device is different, sammsung could not use the lowest value, but even some 100mV could improve the battery life of the phone, and since not everybody is tweaking his phone as us, it would have made an even greater phone OTB...
PS : my configuration
Phone/Pda/CSC : XXKG5
Kernel : ninphetamine 2.0.5
Yes, lower voltage is better but not all chips will take it. With undevolting the main risk is random instability or reboots, if you get a reboot just scale your uv back by 25mv and see what happens.
As far as why the voltages are what they are, for a chip as young as the one in the sgs2 there is a lot of variance in the chip, not all will be as "good" as others, so samsung bin (select) them to hit the clock they do at the voltage they do at a certain yield (aka not to many chips unable to hit the needed specs).
Maybe in the future the stock voltage will be lower, but for the time being we can tweak and see if we got a gold sample (better than standard) chip.
Also as far as your uv settings, you are not at 600 or something mv, the kernel has a hard lower limit of 800mv, even if it slows something below that in setcpu, the minimum the kernel will give the cpu is 800mv.

Thank you very much for your quick reply ! And sory for being late too ^^
I indeed re-read more carefully Ninpo's thread and saw his kernel can UV from 800mV to 1500mV. Btw I think because 600mV was under the limit, stock setting was applied.
So after a day of testing, I can say my phone handle 200MHz / 825mV, 500MHz / 850mV, 800MHZ / 950mV, 1GHz / 1075mV and 1,2GHz / 1150mV with no problem at all And now, my battery will last forever

To make it last forever you want to set it to 0mV
Just don't set 200mhz to low or your phone may suffer from the sleep of death where it won't wake up.

Haha, if I could do it !!!
Thanks for the advice, if it doesn't wake up, I'll put the 200MHz voltage a bit higher
Alright so I've been tweaking my cpu using setcpu. So far I've been forcing it to run on each stepping while i drop the voltage 25mV at a time. I've got both the 200 and 500 running at 850mV no problem. The problem occurred when after i set my 800Hz stepping 850 mV and then returned my min back to 200mhz. It locks up every time. 800mhz runs fine on its own @850mV but not with other steppings. I've been told before that big jumps in voltage between steppings can lead to instability but i have all three at 850mV. I was just wondering if anyone m ew why. Also if i force it to run only one frequency will it still go into deep sleep? Thanks
I don't know if this is tandard on all kernels but on my kernel for example the steps are like that:
1000mhz=1175mv
1100mhz=1225mv
1200mhz=1275mv
Now at THIS point it starts getting weird. Suddenly the voltage increases by 25mv each
1300mhz=1300mv
1400mhz=1325mv
then it's 50 again
1500mhz=1375mv
then 25 again
1600mhz=1400mv
I know a bit about overclocking and overvolting CPUs. And I know that the higher you go the bigger the steps to increase voltage have to be (assuming you always choose the lowest voltage possible on which everything is stable). That's just due to physics. And now the opposite is the case... Why is the step from 1,5ghz to 1,6ghz only 25mv but from 1000 to 1100mhz it's 50mv? This doesn't make much sense.
Seriously no wonder that my phone is instable on 1600mhz. I guess the voltage just isn't high enought so the transistors aren't able to do their job properly within that short amount of time they're given at 1,6ghz.
Are the voltage steps like that on every kernel?

I'm on Siyah 2.6.14 Voltage Control setting as follow:
I/O = bfq & Governor = ondemand
1600Mhz - 1500mv
1400Mhz - 1300mv
1200Mhz - 1200mv
1000Mhz - 1100mv
800Mhz - 1000mv
500Mhz - 950mv
200Mhz - 900mv
100Mhz - 900mv
I've applied these setting as default at bootup with no problem.
OC to 1600Mhz + set to Performance gives me 6800-6990 benchmark score in Antutu.
Which kernel are you on?
Siyah 3.2
I see you are using 1,5V on 1,6ghz. Maybe that's why you running stable?
When I set max clock to 1,6ghz and 1,4V at that clock then I get random app crashes/freezes... Once I tried shutting down my phone and it made some very loud and creepy noise... Some very loud beeping. It was definitely not the shutdown sound of the rom.
On my stock rom I just get random reboot.
Can you also permanently work on 1,[email protected],5V (setting min clock to 1,6ghz) without freezes/crashes?
Also funny that at 1400mhz you are on 1,3v while standard on siyah 3.2 is [email protected],4ghz
While 1600mhz is lower voltage again.. This is messed up
