Underclocked cpu?

I was browsing my system info and it seems my cou is running at 800mhz? Do u guys also have this as the standard

I mean when I view the system info in Quadrant, it says the cpu is underclocked

samsung built in an ondemand power bias, it will scale up to 1ghz if needed but will most of the time sit comfortably at 800

Cpu speed is self throttled. It won't run at 1gz unless required by whatever it is you are asking the device to do. This is to conserve battery usage. Ie: The phone doesn't need to run at 1gz to play solitare smoothly but might to play a video or 3d game.
Edit: I see someone beat me to the answer.

Daily min/max CPU frequencies?

First off I apologize if there is a thread like this lying around somewhere.
Now I made this thread because I'm curious about what frequencies people usually have their phone running on.
Mine's
Min:100
Max:400
Governor: SmartassV2
Go ahead and post yours!

-25 uv across the board on all frequencies
When at work i can run podcasts on blue tooth for 5 hours, surf web on 4g (usually checking the forums) for 30 min during my 2 20 min breaks. This is my usual 8 to 9 hours from pulling it from the charger to getting home. Rarely do i have to swap batteries before i leave work (i have 3 batteries) but can usually make it home and toss it on the computer usb if i don't want to swap out my battery.

I CALL BS. No Way in Hell not even on Any platform will it be fine it will lag and be unresponsive at those low frequencies.
Make a video and put it on Youtube i want to see this if i UV as well it also decreases performance but gains battery life.

Not that I've tried it... but we all know the Epic is more than twice as fast as some devices that run Android. In that case, how would running it at 40% speed make it unusable?

Umm no thats wrong.
HTC EVO Shift 4G can be over-clocked to 1.9GHz from a stock 800 MHz: 110% OC
HTC Rezound can be overclocked to 1.99GHz from a stock 1.5GHz: 49-50% OC
Moto Droid X can be overclocked to 2GHz from a stock 1GHz: 100% OC
Theres plenty the Samsung Epic only has technically a 30% overclock and virtually a 50% overclock
But theres plenty of other phones with more over-clockability

I run 100/200/400/800/1000/1200 all stock. Its what samsung intended the hummingbird for (our processors were designed to go 1.2ghz iirc)

Well because our phones are 1.2GHz Stock but they lowered to 1GHz because that was the margin in 2010 for high end devices but they Under Clocked to save some battery. So technically we only came up with a 30% OC (1500MHz).

Galaxy s3 hot problem and soloution (experimental)

Hi guys I am from India and on international s3 and face a problem that s3 get hot upto 48c
I have a solution for this(must be work)
1. First of all disabled bundled stock apps like chat on etc I have attached a screen shot of disabled apps on my s3
2. Off NFC android beam.
3.disable s voice( big battery eater)
4.must disable s memo and exchange mail
5.clear cache of all files and apps weekly
6.flip board users plz clear your cache routinely( this apps has a network bug that eat more battery in less time.
7. Set sync of apps like Google +,mail,wheather to 6 hours.
Screenshots are below.
Plz tell me after disabled these apps attached below that the tricks work or not

48°C is really like nothing. I remember SGS 1 & SGS 2 especially were getting almost 60°C.
So - unless some expert denies - I'm pretty sure temperatures up to 70 will not make harm.
With one exception: temperatures above 40° will shorten battery lifespan in the long run. Li-ion batteries don't like this.
Sent from my Galaxy SIII

That sounds crazy, 70°Celsius? How can you actually still hold the phone on that temp? Almost impossible. My S3 never reached 40° Celsius once so far. But i remeber my HC Desire, when it was very hot outside, it reched almost 50° Celsius and it was HOT like **** in the hand i couldnt hold it very long tbh. And i dont think that this is good for the phone.

70°c can damaged your s3 CPU and you cannot hold the phone. So plz don't make such a comments on temp.

My device is at 40 degree at normal use

I have read (will post the link if I can find it again) that if a battery gets to 140°F then it can go into a self heating mode, not allowing it too cool down, and eventually catch fire. However, I have accidentally left my dx charging in my car on a hot day and when I came back out, it had shut down and had a "battery too hot" notification. That phone would power off if it got too hot.

My gnex once hit 110c CPU temp and it still works fine, it was regularly hitting 80-90c during benchmarks.
To say that 70c will damage a CPU is absolute nonsense, a quad core CPU running at 1.4ghz will hit 65-70c no problem under full load before temperature throttle kicks in and limits the frequency to cool it off.
Battery temp is a different story, 70c battery temp will probably end up damaging your phone/battery.

Yes I do mean Celsius, and a CPU isn't made of water...
It shut off as that is the safety cut off point for that particular CPU.
I had temperature throttle turned off.
Quite a few people have hit that temperature, go to the gnex forums and ask Simms22 if you want further proof.
I KNOW a CPU can handle that heat because I have actually seen it.

Hi,
I agree with nodstuff and I can confirm
The same thing with my Gnex (not with the same kernel ) With a modified CPU temp limit my Gnex is going up to 98°C, never try with the CPU temp limit disabled but indeed it shut down at 110°C, it's a fact and it's in some doc of TI.
And about the temp of the SIII here we talk about the temp of the battery, not the CPU temp, this is not the same thing, although there is some correlation (but actually with, for example, a battery temp of 50°C, we don't know the real and actually CPU temp)..
When will you have an CPU temp in the SIII??? There is a CPU temp sensor but If I'm not wrong for an application to read the temp the kernel must support it (it's hardcoded).And as far as I know actually there is no way of knowing the CPU temp.
At first with the Gnex it was the same thing, no CPU temp and Franciscofranco has enabled it (the reading by an app) in his app (and also with anothe 3rd apps after) so we can see the CPU temp in real time.
I really missed this feature with the SIII...

May b it can handle so much of heat ..but the question is about using the device whn its hot..do u think its will b very convenient to use the device whn the device is at 100 degree?
I guess its not possible !

Hi,
Hot for sure but obviously not the same temperature of the CPU.
Temperature dissipated, yes, but not 100% transmitted at all the phone. CPU at 110°C you can imagine that the screen is not at this temperature for example, like the back cover, otherwise beware of burns and it's not the case.
When my Gnex reached 98°C it was hot but not unable to hold in hand.
Guys, you never used a Gnex (or another phone maybe) without a CPU temp limit, so disabled, or a modified CPU temp limit with an higher limit before thermal throttling...? The phone is still usuable.when I read you speak about very hot, extremely hot, or overheating with a battery temp of 45°C... Should not you know the CPU temp...
Ok the battery temp could be useful but not as much as the CPU temp...

Nodstuff why you not understand the temperature theory for CPU or mobiles if your CPU take in 110°c temp it can caused many problem and reduce deficiency of your CPU.

[Q] Does overheating kill my S4 (I9500)

Does the overheating eventually kill my S4? I have CM 11 (Android 4.4.2) and the problem still persist. I can't update via OTA since its rooted. I also don't want to lose any apps because they are large apps and dont want to bother to download them again. So will it actually gonna kill my S4 someday?

The Android 4.4.2 for S4 is leaked version. It is not published Officially by samsung and it may has many bugs. (eg. overheating, ...)

Overheating can eventually cause some serious problems. The board is able to adjust slightly with flexing caused by heat, but eventually soldered connections will give in and break if your device is getting extremely hot. When or what is causing it to get so hot?

Not a little bit hot but perheps if it reaches 85 degrees+ all the time. But even in doing so it will still (from my experience) last longer that you'd ever keep this phone for.

They have quite a few apps out there for monitoring temps and whatnot. I personally use Android Tuner for everything I monitor. As a huge plus, this app is one of the most versatile apps (especially if rooted) I've come across and have had for a long time. Its good for adjusting or tuning down anything that may cause overheating as well as view summaries of the culprits

I agree. You don't hear too often about someone's phone overheating to the point of failure. I've seen one phone that would get so hot you almost couldn't hold it in your hand, and had a habit of doing that but was ultimately broken months later by a shopping cart.:silly:
Still a decent monitoring app (among dozens on the market) can help you monitor temps and pinpoint when, where, and what is causing problems.

Thank you the app works. Is there anyway to drop the temperature as low as you can? Like 26 C? I disabled my Google account stuff and sync and removed the sim card because I use this phone as a gaming device. When I play a few rounds of subway surfers it already gets to medium warm and for 3D games it gets warmer more faster.

I would say you are safe in that temp range. Its when you get 80 C and above that that's causing damage. Also are these temps from the battery or the CPU? The CPU can and will get to 60 C temps at times which is normal.

If you are having heating problems while playing 3D games alone then you might want to try experimenting with using different GPU settings. You can try tuning down the frequency. It may or may not help with temp being its only a frequency setting. Try also using the app "Greenify" to put as many of the remaining apps that you don't absolutely need running into hibernation. Greenify is a lot more efficient when it comes to keeping apps from using resources.

How to adjust the GPU frequency settings? Does this affect the quality of the game after its adjusted? But I do not think adjusting the GPU frequency settings will work. The overheating problem is caused by the CPU. May try Greenify app.

If your GPU is capable of adjusting the frequency then it will show you in the Android Tuner app next to the CPU settings, but you're right it wont help with overheating. You can set your CPU governor to "powersaver" and underclock by sliding the max frequency setting down one step at a time until you notice a difference in temp. Greenify is a huge help mainly with battery saving which in turn stops a lot of unnecessary CPU draw.

Does under clocking CPU will cause large 3S games crash? Hope it doesnt

Bad idea. When I change it to power save it makes every sluggish and laggy even I turn one step down the CPU thing its sluggish

Phone overheating issue

My G2 tends to get worryfyingly warm when im using a bit more cpu intensive tasks. The cpu managed to get to 67°C when playing 3 races in NFS Most Wanted and managed to get 76° when doing Antutu benchmarks twice and it started throttling. And battery temp stayed around 40~45°. Idk, if this is supposed to be normal(please bear in mind my previous phone was HTC Evo 3D, which barely got hot ). When idling, the phone is just a bit warm. I'm running OptimusRs Pro V4.1 Stock kernel. Is this supposed to be normal for quad core phones or should I get it to service?

Sent from my LG-D802 using XDA Premium 4 mobile app

Is it really normal? I mean after 10 mins of browsing even the screen gets really hot..

see if you can check your kernel's cpu profile settings. could be that it's not allowing the cpu to idle when it should be. alot of times there are various profiles you can set it to 'on demand/powersaver/ect...' and this will change the behavior of the cpu's throttling.

Well now we're in the summer and the phone will naturally get hotter since the only thing that cools it down is the environment. If you're browsing under hot sunlight with 100 percent brightness then yes, it is going to get really hot.

its not normal bro. i have the same issue on all aosp roms and cloudyflex roms. my phone becomes really hot. if you give a shot at cloudystock 2.2, your phone wont heat up at all. try it out and be sure to make a nandroid before. just incase if you change ur mind and want to get back to this rom. i wouldnt recommend it though, anthing above 25*C for the battery is bad for its health since its a lithium battery.while the cpu heating up to 70*C is fine i actually use custom throttling to reduce my phone heating that much, i keep the throttling at 60*C

No it gets hot even at 60 percent brigthness while browsing. NFC, BT, 3G are off, i am using only 2 widgets, The top of the phone gets really hot... my sis has S3 and it never ever gets that hot, so do my old Huawei phone..
