My sensation is currently overclocked at 1.73ghz, and according to a temperature widget I have it seems to hover between 25-45 degrees. I can only find the one temperature reading, so I think this will be the battery temp. I've set setCPU up to run at 1.73ghz below 35 degrees, then come down to 1.5ghz above it. If it gets to 50 degrees, it's then set to drop to absolute minimum and play a warning sound. I've also set it to drop to minimum when the screen is off to save power if the phone doesn't sleep, and to not exceed 1.2ghz when on charge or during a call. None of them are fixed, they're set to intellidemand or whatever it's called.
Do these settings sound reasonable? What sort of temps would be deemed as normal? I don't want to shorten the life of the phone if I can help it.
Also, if this temperature reading is just for the battery, what would I need to monitor CPU temperature too? Is there an app available so I can actually log the temps to see what happens when playing games, etc?

System tuner pro shows CPU temperature and does logs.

Cheers, I'll give it a try.
What sort of temperatures are acceptable before I risk the CPU's lifespan?

Why do you need these over clock speeds? They will only ultimately increase temp, burn excessive battery and reduce the life span of your device.
Use common sense, these speeds are only worth using for bench mark tests
Personally anything above 43 is to hot for my device, although not same as yours, you can use set CPU to throttle down at this temp

I mainly wanted to overclock since the normal sensation was underclocked in the first place, the sensation xe runs at 1.5ghz and the CPU is the same. So I wanted at least that. What I'm wanting to do now is find how quick it can be before it starts running too hot. Just wondering what's considered too hot in the first place.

My web browsing is much better (faster and smoother) at higher clockspeeds and performance governor. So that's why I run higher speeds. I use my phone for internet stuff more than anything else.

Mine seemed smoother too, for normal use and for my emulators. I found a problem though, setCPU wouldn't let the phone sleep so my battery went from 85% to dead overnight! It also seemed a little unstable even when turned back down to 1.53ghz, so I've uninstalled it and it's now running 1.53ghz just from the kernel. Runs perfectly now and battery life is back to normal. No noticeable difference in performance going from 1.73ghz down to 1.53ghz either, but now the battery temp seems to top out at 35-40 degrees or so, so about 5-10 degrees less than when it was set higher. I'll still give that app a go though so it can monitor and log temps while I'm playing games, etc.

I am loving my Android experience so far coming from and iPhone 4. I am running LeeDroid and have been playing around a lot with SetCPU. At this time, I am not concerned about battery as of yet. I am asking this question in regard to optimal, blazing fast performance with minimal hiccups.
I have done Quadrant testing at various min/max CPU levels. I had excellent results at 1804 high 904 min. However I had to yank the battery after not being able to unlock the device.
For profiles, real basic, again I am not concerned about battery charge life ATM. I have it set to revert to stock performace (1036/245) if the battery temp reaches 100F.
With the screen locked, I have it set to 499/245. All of my settings are using the "ondemand".
I would like to know what an ideal minimum is for PERFORMANCE as well as ideal max (1804? Highest might not always be fastest?). I got amazing results with Quadrant full benchmark with settings of 1804/499. This also caused a lockup when trying to unlock the device though. Maybe because there was a conflict with my lockscreen max setting? I would think the app would put priority to the lock profile though.
Also, does this phone have a built in CPU temperature sensor that I could utilize with a CPU temp widget?
Thanks for reading my lengthy ramblings.

Not all Processors are created equal and therefore some can OC to 1900+ and some cant overclock at all. Most will be in between. Sounds like you are over doing it. I clock mine to about 1400 when charging. I have had it to 1700 without an issue at all, but I don't find a need to be faster then 1400. When screen is off I actually tell it to go to 250MHz. Sometimes its alittle slow to "wake". But it saves mucho battery. When just on battery I am running at about 1250. Been this way for about 3 weeks. Not an issue.
I have never had to yank my battery and quite frankly if I did I would never run it that high again. You are going to burn it up running it at that speed. Nothing over 1500 for extended periods. 1800+ for showing off maybe? But that's kinda dumb too.
I have not read about any built in temp thing so can't really answer that.
I don't know what kind of power hungry apps you guys are running, but I run mine underclocked to 906MHz. Snappy as ever.
As the thread states, I obviously have a question about SetCPU and processor settings.
Is it better to have the processor underclocked and almost always using 100% to use programs, or it better off to overclock and have more processing power without using 100% or close to that mark.
And what would be more beneficial for battery life.

Actually we could use some hard evidence regarding this. Theories are theories, but actual experience is golden. Maybe you could try some various processor settings are report back?
Well, before I posted this I was using 245/886 underclocked with 245/245 screen off profile. At the end of the day I had an average about 75-80% percent battery life with pretty moderate to heavy usage.
I'm current using 245/1574 overclocked and will report back, with same screen off profile.
And yes, I did wipe battery stats before I started this.

Cool, thanks for that info. Are you finding that forcing a 245 mhz screen off speed is impacting any apps running while your screen is off (e.g. music playing apps)? A couple of weeks ago I tried forcing the screen off at 122 mhz to see if that would help battery life, but I had big problems with music apps stuttering. I didn't play around with the speeds to see if raising the forced minimum to 245 would have fixed the problem. Some kernels advertise as a feature "Max speed - screen off 576MHz" or some other speed, but I don't know if it needs to be that high or not, for app stability.
I personally haven't tried any music or apps running while screen is off, I'll give it a whirl when I get home from work.
I know this obviously will vary from phone to phone, and how the user uses the phone. I'm pretty moderate to heavy usage daily. Hopefully maybe we can compile some data on what works for people.
I have my screen off profile set at 245 and have no problem streaming music from my SD card with the screen off. When streaming from the cloud, I sometimes get a very long pause between songs that isn't there with the screen on. I will try raising my screen off speed to see if that changes anything.

I noticed this yesterday. My screen off is also 245. My music stuttered, but only once (and it was fairly brief).
I raised the screen off speed to 368 and have not had any sputtering or long pauses between songs, even when streaming from the cloud.

I use SetCPU at 460/1152 brazilianwax, screen off 122/537 conservative and have good battery life and no issues when playing music w/ screenoff....
Overclocking is almost guaranteed to worsen battery life compared to say if it was at stock 1 ghz or a little less.
With a governor like on demand, its gonna scale from the lowest to to highest allowed as soon as it gets some load on it, eg from 245mhz to whatever Max is (1017, 1075, or 1920 etc), without stopping in between.
Even conservative with fast scaling will probably scale close to Max clock speed pretty quickly under load, so theoretically this should be a /little/ better for battery than on demand, but will not seem as fast and could possibly make the phone seem more laggy. Smartass is very similiar to conservative as it scales depending on a preset % of CPU load. If its set to 70%, when CPU reaches 70% load, it scales to next frequency, when that frequently hits 70% load, its scales again. The version of the on demand governor most of us have in out kernels is the fastest scaling option, which goes from min CPU - straight to max
I saw. 3 kernel.
Slightly. Uv
Midle. Uv
Extremely. Uv
What are the differences. Between. Those. ????
Sent from my myTouch_4G_Slide using xda premium
Saw that too - exciting!
UV is undervolt, which means running the device with less voltage (electricity). Uses less juice, battery lasts longer, and doesn't run as hot.
Depending on what you do with the device and how it's implemented the results could range from awesome battery savings without a reduction in performance to brownouts and having the processor work harder to get the same job done.
If you do a lot of processor intensive stuff ( resource heavy games, for example ) undervolting becomes a harder thing to take advantage of because the processor has to work harder when it gets maxed out.
The fact that tbalden lifted the artificially low 1.2 clock speed and bumped it up to it's rated 1.5 offsets that somewhat.
For most people undervolting is a godsend, because they don't miss that top % of maxed out processor performance.
Also, the greater range of speeds allows you to regulate the speeds of the device using apps (setcpu maybe) which can't set speeds outside of the range the kernel allows.
Tbalden got into what I was trying to before my crazy work schedule hit, and he is doing a whole lot for this device - now I'll be following the trail he's blazing instead of the other way around - win for the MT4GS community when people have time to make fun stuff like this for us to play with.
Haven't had the chance to read up on what he's done with it other then seeing it was there, so this is some general info to get you started with, there's a lot more to be said and I'm sure others will swing by and add to this description.
Sent from my Bulletproof_Doubleshot using xda premium
Slight is slightly undervolted, meaning it saves less on battery
Middle is around 5% undervolted, meaning around 5% saving in battery drainage
Extremely is 8%
Depending on the quality of your cpu material, it can work on your CPU well, or if it is made of a silicium chip that is less clean then your CPU will say voltage is too low, and phone might reboot. So depending on your device it may or may not work out.
UVing the cpu means no performance decrease. You should find out which kernel is best for your device. Safe is to go from Slight to Middle and then to Extreme if the Middle works out well. If you have reboots, fall back this way: Extreme --> Middle --> Slight
Also, if you dont want to use the Overclock frequency range, use SetCPU or an alternative cpu tool to cap it to your like.
Thanks guy. Now I understad why my phone s batt last longer . I flashed the extremely kernel . And I'm using an anker batt. And adding profiles with set cpu
And I noticed. My battery. Last way longer then before . Even though. I set the main profile of the set cpu to 1.5 hz max. 1.0 hz min. Wich makes the phone run as. My loptop. . Thank u developers

I have been noticing bad battery life recently and I checked my setcpu settings and for some reason my phone never goes below 602 MHz. I have my profile set to 389 as the lowest frequency. I was wondering if anyone knows the problem and if there is anything I can do about this.

there was another thread (Here) about 5 days before you posted this. Read that... this is just part of what i posted:
this phone (and alot of newer ones) are using an idea called Race to idle.
this means that the cpu will kick its cpu speed up higher than it needs to get things done faster, so it can get back to a low power idle state faster.
In reality your cpu is really going in and out of sleep states hundreds or thousands of times a second, the frequency is just kicked up so that it can spend less time computing, and more time sleeping.
for the hell of it try downloading an app that shows you cpu usage in %
that number is the amount of time that the cpu is in a fully awake state vs being in its first stage sleep state, LP1.
if nothing happens for a bit longer than it will go into an even lower power state called LP2. frequency can still be set to a higher number (like 600mhz or even 1ghz) but the cpu is actually not doing any calculations. its sleeping till something needs it.
also, changing cpu speed takes a long time (cpu wise), the cpu has to pause, change speed, then wake up. so the less it does this the less lag you have.

My HOX running on 4.2.2 Sense 5 stock rom is having heat issues i believe i dont know if its normal
PS default Kernel (still cant get Beastmode,god knows why)
i use "ondemand" as my governor and "noop" as my scheduler with set cpu
i also have trickster mod installed but i use it only for monitoring temp and on what frequency is the cpu running!
when its idle temp is temp of cpu is 35 degrees Celsius and battery 26 degrees Celsius
whenever I am using my phone for internet for benchmarks etc CPU is 40 degrees Celsius and battery is at around 32 degrees Celsius
the phone feels ok
but whenever i start any game no matter how simple it maybe (this applies for a wide spectrum of games ranging from * ball pool to demanding games like Asphalt 8) i notice my backside especially region around my camera getting warmer (now its not very hot but you can tell the difference)
at that time the reading shown is CPU is 45 degrees Celsius and battery becomes 36 degrees Celsius
PS the phone never restarts the game doesn't crash it runs smoothly
is it normal!?
i have read on web that lithium polymer batteries should be kept below 35 degrees Celsius for optimum life and performance
i dot have any background apps running whem i am gaming and the rise is observed in a few minutes or so i usually play a game for max 15 mins after that everything cools down!
this rise is also observed during taking back up through Twrp!
Those temps seem totally normal. Yes, higher temperatures are stressful to Li ion batteries, and hasten capacity loss. But to some extent, you need to try not to worry about it, and enjoy the phone for what it is.
While I don't game much, I do notice the phone getting warm while using Navigation, Netflix, etc. I've had my EVITA since just after release in May 2012, and I haven't noticed any loss in battery life.

thanks u saved me i was thinking of what not like under volting and all those tweaks with the kernel!
Btw redpoint is i know the nature of ondemand governor but in my case it is either the max or min frequency it operates,so is it a good idea to switch over to powersave?
(and does our kernel support that)

Haven't used SetCPU in a while, but pretty sure if the option appears in SetCPU, its supported by the kernel. Depending on what kernel you have installed, more or less governor options will be visible.
Governor seems like a trial and error type of choice. It depends on how you use your phone, and not everyone will get the same results.

66° Celsius. seriously and that too the battery?

besides the phone doesn't restart or get damaged?
Yep, 66° battery temp. That isn't a normal operating temperature though, that was while my phone was rendering a huge picsphere image from the Focal camera.
There are safeguards in place in case the phone does reach a temperature that would damage the phone. The phone will first warn you it's getting hot by flashing the led red and green, if it continues to heat up it will shut down.
