I've been using my phone constantly for a few hours and the battery is at 41°C which is almost out of the safe limit of 45°C is there anyway to keep the battery from getting to this state??

What is you clockspeed?

Maybe you should lower the min? it might be a problem. I don't know.
Could the outside temperature also be a contributing?
Sent from my u8800 using xda premium
Maybe, but your minimum speed is most likely the contributing factor. By keeping it at 600 you're telling the phone to always stay at that speed, even when it doesn't need to and it's trying to idle to save battery
If you want to keep it at 600, do so but at least use SetCPU to create a profile that'll set the minimum to ~245 MHz when the display goes off
Disregard me, sorry. I didn't see that you were using your phone constantly
The battery of the x5 is a LiPo. The critical temp of a Lipo is 60 degrees. When the temp is over 60c it will lose lifetime.Ofcourse less temperature is better...Myself I own many really big lipo packs (RC hobby) and they are just good at 45C. But this is a phone battery so.....atleast I can say that 45c wont really harm the battery, If you aren't using 24/7 on that temp. The battery temp of my stock x5 is usually 26-34c.
Aslong as your fingers aren't burning......everything is OK

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.

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.

Do you really mean Celsius? Water boils at 100°C and I don't think that a CPU could even stand such heat..

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 !

Comparing it to oven is very wrong, as oven gets 200-300°C.

Its not just the cpu.. when the heat is dissipated the whole area including the screen gets hot.

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.
Other people are saying all this thing so plz listen carefully and don't run your phone on 110°c

Mine idles at 55 degree Celsius and throttles at 60 so there isn't much room to go. I can increase the throttle temp but was wondering if that's safe and how much heat can nexus 4 handle
Sent from my Nexus 4 using xda app-developers app
The CPU will run fine up to 100°C at which point the phone will shut down to prevent damage.
The battery will run fine up to 60°C at which point the phone will shut down to prevent damage.
The CPU will throttle default at 60°C which to me is a little low.
The battery will run fine up to 48°C at which point it will report it's status as overheated and throttle.
I have my CPU throttle at 75 and have been fine for months. I would advise not raising the bar too high because I'd say you up it to 90. All that you will accomplish is raising the battery temp quicker and thus still end up throttling.
The battery temp is generally the heat that you feel coming through the phone. So by making the battery heat up quicker by upping the CPU throttle threshold. Your device will become hotter to the touch quicker.
There is a balance between the 2 which I feel Google got wrong by setting the CPU threshold at 60. I would advise 70-75 but that Is purely my preference.

So the phone will run fun until battery is 48 or 60? I think 48, 60 seems too hot

It will throttle at 48. It will shut down at 60

I've seen a few post on how to undervolt but I'm still not 100% sure how or if I should, I'm guessing it gives a little bit more battery life ? Also what app would be the best to use ? And the best values to apply

you have to install custom kernel for undervolting.. and it does not give you battery life..it reduces how hot your phone gets..
It can increase battery life actually, not hugely but ARM processors used in phones use a few watts, wattage is calculated as voltage * amperage, less volts going through the lower the wattage, ergo lower power consumption resulting in extended battery life. /rant
OP you will need a kernel that supports UV (pretty much all non stock) and a UV interface, I prefer trickster mod. Look for core voltage and knock it down a step (-25mV). Then stress test / benchmark, if you don't freeze / reboot then you can knock another 25mV off, keep doing this until you get the minimum voltage your phone remains stable (for me 1025mV @ 1.5GHz). You can then set for the options to stick on boot.
