Phone is hot - Samsung Galaxy Nexus

What's the highest temp you have seen your phone at? Mine currently is at 105° f

I have hit almost 120 F before. Not much to worry about if you're a casual user. Thermal throttle should just kick in.

highest ive seen is a cpu temp of 109C. btw 109C = 228.2F. the devices safety shutdown is at 110C. i have a feeling that you posted a battery temp of 105F. 105F for a cpu temp is quite cool, considering the body temp averages at 98.6F.

Oh damn lol I didn't know that

Oh, I assumed you meant the battery temp indicator that most programs give out. I'm not sure what I've hit on my CPU, but if you hit a temperature too high, cpu or battery, thermal throttle will either scale down the frequency to cool down your processor or turn itself off/reboot if the cpu or battery hits too high of a temperature, thus saving your phone.

Voltages

What will happen if I raise the voltage on my phone

You can raise them just not to much. If you go to high you might get boot loops, or you might fry something. Why would you want to though? Higher voltages just run the battery down faster and provides little to no noticable improvement in performance.

What temperature is considered "overheating"?

I have been overclocking my CPU lately, sitting good right now at 1.2 ghz. I have it undervolted as well to prevent overheating. My question is what temperature do you associate with too hot? 100 F? more?
I dont like letting my phone get over 95 F, but im just curious to know what is considered a safe temperature range.
I cant directly measure my CPU temp, as that feature is not offered on our phone which really sucks, i have to go by the battery.
I have not the slightest clue but I would think you would go by how it feels in your hand and whether or not you can "smell" the cpu burning. I usually dnt clock it above 1.2 unless I'm gaming which is bad but I have it setup by a laptop cooler so it never overheats. Id say anything more than 90 would be pushing it.....

Not true put it like this our phones automatically shut off @ 122*F I go to 115*F when i play GTA 3 @ 1.5Ghz, but i can clock to 104*F just streaming music on WiFi.
So id say personally probably around 110*F+
Yes 105*F is hot but don't run it that high forever though.
But thats the battery, CPU stays fine so id say if your running 100*F+ For more than an hour than it might overheat??? Not completely sure but like i said everyday i play GTA 3 and get up to those temps.

Do you undervolt your cpu or run it on stock cpu voltages? I'm currently running samurai assassination and my phone always crashes if I undervolt it, and usually crashes when I run it at max voltages, but only when I overclock.

I would consider 114 f overheating, that's when I have setcpu underlock to 800 mhz

Used to but because i play GTA 3 now i dont if undervolt that defeats the sole purpose to overclock so i can play without lag, once you undervolt it decreases performance but however gains in battery life.

His epic is weird undervolting drops his preformance whereas mine increases preformance......

I would agree, 105, 108 would be ok but not for extended periods. Taking the back off usually cools the phone almost 5 degrees for me, but Epics are weird

Yes and has ability to set I/0 Scheduler plus setcpu reads wrong. And is outdated.

I'd say that everyday during the summer in Phoenix I'd be overheating as the daily temp rises to 115+ for weeks.

I do this too, for the battery anyway. If it overheats I uc. If I'm under %80 I uc to 800, %50 600, 30% 400

But not an option to Overvolt, and choose an i/0 scheduler. plus its a bit faster to use and works with other programs nicely

How much do you undervolt?

My S3 was getting really hot after rooting so I decided to try undervolting. I was able to under volt each clock speed by -100mv, and my device hasn't seen any performance issues, runs cool, and battery lasts way longer! What do you guys keep you voltage settings at?

It doesn't matter what other people UV since all devices are different. I can reach -125 all steps (haven't tried farther) but some others can barely do -25. It's just how their device is built.

I understand. I'm just wondering what people are running at
Sent from my SGH-I747 using xda app-developers app
The reason I personally don't do both under clocking and over clocking is that the phone itself isn't made for that. I personally don't know what this phone can handle. I have seen people under clock and over clock phones and have it work while some people have phones that can't handle much at all especially the refurbished ones. My S3 handles it well but I only tried it out once. That's my feeling on the subject. If you do do either undervolting, under clocking or over clocking just remember to do it responsibly and not put it to highest power and leave it there.

Cpu Temp

Hey all, any idea how hot it is safe for the cpu to run? Using trickster mod to read the cpu temp after a few hours my cpu can reach close to 70 degrees Celsius and the screen feels hot. That seems a little insane. I thought it was aosp rooms causing this but after switching to i747z I can confirm that is not the cause of the heat. What do your cpus run at? Any ideas?
Sent from my SGH-I747 using xda app-developers app
Mine usually stays under 100°F.
I wish mine stayed that cool! I'm consistently around 120 farenheit with the screen on

The battery temp or the cpu temp?
Mine tends to get hot too, sometimes almost too hot to touch.
But never over 70F.
Usually between 20F and 60F, it tends to stay around 50+ during activity.
Im not really comfortable with how hot this thing gets sometimes. I'd be downright alarmed if my cpu temp was over 100F.
Oops, that's battery temp
CPU temp seems to stay around 40C
My bad!

Okay guys this thread gave me the answer i was looking for
http://forum.xda-developers.com/showthread.php?t=1725813&page=4
Turns out at 70 samsung starts throttling the kernel to cool it down so anything up to 70 celsius is totally normal

Is this cpu temp normal

I have lyapota kernel with undervolt but get this cpu temp. Is this normal?

That looks extremely hot my friend, I have never seen mine that hot.
What was your phone doing to reach those temperatures?
What are your settings?
Which version of kernel?
Governor?
Voltages?
here's my temps
Using lm#17 pre aroma
-75 cpu undervolt
Even under full load I'm only seeing a maximum of around 50-55

Highest at 81°C is normal...it won't go pass that. Stock kernel capped at 85°C. When reach at that temp, CPU will be throttled to maintain below capped temp.
Just don't play heavy games while charging. Almost can fried egg with this phone. [emoji39]
