Will the Note shutdown if it begins to overheat or will it just burn up?

Wanted to ask the same. Also what's ideal setcpu temperature profile?
When I'm outdoors temperature rises to 44°c in fifteen-twenty minutes (when using G maps/opera mobile). I have set fail safe alert on 44°c.
Is it safe to set 50°c alert?

I run between 40 & 50C pretty much all the time. It is summer here in Oz (but not that warm this year), but I am not sure how much difference that makes.
I am using the abyss kernel with the abyss governor. If I use other governors it can go much hotter, so I do not. With stock kernel it was more like 10C lower.
at 40 to 50C all seems well (bear in mind this is the battery), and usually I get less battery drain than the stock kernel. It rarely feels hot, so I am not sure how accurate that figure is.

after overclocking to 1.4ghz and letting stress test run for about and hour, my CPU temp showed being 50 celcius. thats where i stopped.
do we know where the tempurature starts becoming dangerous for the device? i would say mine ran for about 15 minutes at 50 degrees and it didnt seem to effect it.
maybe its a dumb question because i doubt i will do anything with the phone on daily use that will push the temp higher than that.....mostly out of curiosity.
nobody knows what the max safe temp is?
50C is too hot. Stay under 40C imo.

Right. I wonder how u got urs to 50. Mine heats up at just 46, and that is when I stop what I doing n let it cool down. 40-42 can be considered safe.
well. i fugured out that the cpu only gets that hot when i can setCPU in use, and set to performance.......wich i have sense discovered is a bad idea and no longer using setCPU for anything.
i ran linpack for 20 minutes yesterday on my new setup and it only got to 43. though the phone did lock up at 22 minutes.....thats probably a whole other issue
My note gets really warm when doing things like playing tetris and browsing the app store is this normal?
What's your setup? Kernel, Rom, OC, Governor etc..

Had the same problem too....sometimes when the phone is hot, theres a delay between making calls and the phone actually dialling. For info i'm on standard kl3 rom rooted with cf kernel. Phone is on on demand gov standard speed 1.4ghz. Appreciate any help...thanks.
I'm running Abyss 2.3, 100 - 1400 with Smartass V2 Governor. And it works fantastic I must say. You might wanna try a new Kernel FM 1.5 or Abyss 2.3
It's normal for the CPU to warm up when you're playing games and anything causing the CPU to run at max for a long time.
Install CPU Spy from the market and make sure you're phone goes into deep sleep and monitor the other frequencies as well.
After installing new roms or kernels the phone usually gets warm as well. Just reboot and it should be okay after a couple of minutes. That's what I experienced on my Note
Mine is completely stock... Haven't even installed 3 apps yet. The phone is never in a case and the heat appears to originate from the camera area any thoughts or ideas or am I just over reacting?
Btw the phone doesn't slow down or act different operationally just gets warm lol
below 20% of battery power any device getting hot.
plus maybe you making hard time to processor
naw the phone is at 80 percent as well :/ i think im just over thinking lol the phone is operating like a champ just want to make sure its nothing serious
Mine gets pretty hot in same area wen playing games, its just the processor heating up, sure it for force close the app, if it couldn't handle it!
Yeah.. Any processor will get hot when running. Remember there's nothing to keep it cool! So I think if you put it on your cheek and it stings after a while there may be a problem. Otherwise it's pretty normal for the Note.

Just got my note I was wondering if people could share their tips on how to get great battery life on the note!
any tips (even the most basic) will help all us first time Android users
So share your tips, apps, settings, etc!

If you want to save max battery. Turn off 3G and only use 2G. Then lower brightness. Reduce frequency of app updates.
Those are the best tips. I keep brightness on auto. And I keep updates to once an hour for most things. It give me a solid day.

Thanks!
I downloaded setCPU and have it so that the processor goes down to 800mhz when the screen is off.
I am not sure if that is helping or not though.. still struggling with battery life.
Get JuiceDefender Ultimate. It helps to automatically turn off your Data Network and your wifi whenever your not using your phone, it reopens them periodically to check for any updates on ur apps. Smart app and it has saved me x2.3 of my battery life.
thanks!
Do you think juice defender ultimate is better than setCPU?
Disable fast dormancy. *#9900# and the select disable fast dormancy and then save.

Here are some tips for prelonging battery life:
1 - Don't use 100% screen brightness at all times - 50-60% is enough, only increase it when you need to then lower it again.
2 - If your planning to use the phone for long periods, 30 minutes or more constant use then once again use 25% or so brightness
3 - When browsing/surfing the net use the lowest possible brightness as this is the biggest battery killer. Unfortunately our AMOLED screens suck a lot of juice when displaying white...
4 - Try to keep most, if not all applications to manual updates only. Otherwise decrease the update frequency.
5 - Use an alternative launcher. I find for example using LauncherPro uses less resources/cpu/ram than the default touchwizz launcher. Therefore using less ram/cpu saves battery!
6 - If your gonna game for hours then I suggest 0% brightness!
7 - Last but least watch your apps. Some apps are poorly optimized/coded and can take up a lot of ram and cpu which then eats away at your battery!
In my case, disabling fast dormancy helps save some battery. Tough not to a big extent.
Use Screen Adjuster or Voodoo display filter to further lower screen brightness.
Install and use app that has a night mode. Eg, config opera mobile to use a user css to render white text on black background.
Hey,
Before you should know that android collects statistics on your battery in order to "learn" its behavior so within the first days of use you will see a constant improvement if you battery performance.
there are also a few apps that runs in background and has the annoying habit to drain your battery:
wifi sharing
wi-fi sharing manager
social hub
try to disable those apps using gemini app manager or titanium backup.
Thanks for the great tips. My battery lasted almost 19 hours ever since I did everything everyone has mentioned!

Capping the max CPU speed does not help battery life.

How so? I've heard some people on YouTube say they save battery this way..it was the only reason I downloaded setCPU...what are your thoughts?

When screen is off, the cpu frequency is reduced anyway. Thats the advantage of sleep.

YouTube is in no way a reliable source of information when it comes to technology. Unfortunately, neither are these forums, as witnessed by the masses of people that consistently state underclocking saves battery. I've posted about this several times before, and it seems no one ever listens or trusts me, so I'll try to lay it out as simple as I can. This effect is very well known by old school Linux nerds that would push their notebooks to get longer battery lives. Intel calls this effect HUGI -- Hurry Up and Get Idle. It essentially states that the faster a CPU runs, the more energy it consumes, but it *also* finishes it's work faster. Finishing work faster is important as it means that the CPU can go back to it's "Idle" state faster. The idle (or sleep) state uses virtually zero energy. Let me see if I can pull up the voltage table for a phone... here, found this for the Sprint Nexus S 4G and it looks to be accurate based off my memory of the CPU.
1000mhz - 1.25v
800mhz - 1.20v
400mhz - 1.05v
200mhz - 0.95v
100mhz - 0.95v
Now, let's say we have a task that takes 10 seconds to complete at 1000 MHz. 10 seconds times 1.25v is 12.5v (I know, I know, voltage doesn't work this way -- but it's a good enough approximation to demonstrate this effect (and it's to scale!) and I'm too tired to explain volt vs amp vs watt, it's 5am here). At 100 MHz, though, the *same exact task* would take 100 seconds! 100 seconds times 0.95v is, wow, 95v! By capping your CPU to 100 MHz (10% of max), you are effectively using (95/12.5=) 660% more energy to do the same task.
Now, there are scenarios where underclocking can help you, such as when your phones CPU is running at 100% 24/7 because of ****ty applications or leaked wakelocks. Although underclocking does appear to somewhat fix this, it's a complete ****ing hack and won't give you anywhere near the amount of battery life that you'd get by uninstalling the ****ty app and letting your phone go to sleep.
Make sense?

Wow! Thanks! yeah it does make sense! I guess I should uninstall setCPU...I'm not sure what else its used for

That's great, a very efficient way to save battery...
So it's basically like a modern pc running a core i5/i7 that runs at 2.5GHz when idle or when no power is needed. However when power is needed the intel Turbo boost kicks in & increases clock speed to 4.2GHz or even higher depending on what the user set it to.
In my case my PC cpu idles at 3.4GHz & when gaming or video editing it boosts to 4.7GHZ which I've manually set it to.
Everything I see in the market is pretty much battery temp apps instead. When playing games, like Minecraft for example, My CPU (im assuming) feels like it is trying to melt its way out of my phone. I need to find out what the danger temps are and a way for me to see what the current temperature is.
After a quick search, I am guessing that the Note does not have a CPU temp sensor, is this correct?
I am worried about overheating and don't want to damage my device. It only took 10 minutes or so the other night playing minecraft to get the phone extremely warm in my hand. Any suggestions? I even locked it down to one core to try and reduce the power it used.
use tegrak o think
If you have all stock then you have nothing to worry if it burns you get a replacement. If you flashed OC UV rooted usw. Then you can worry about it.

You can check the general device temperature with this.
Hey guys I need help here please, My nexus 6 temperature seems weird so I need to confirm with someone has the Nexus 6
I need to test the CPU and Battery temperature in 3 cases 1-out of deep sleep 2-normal usage like surfing on chrome 3-heavy usage Antutu test can achive that
You can use CPU Temp it will give you all the readings for battery and CPU in graph if you leave it running in the background

It would be great if someone would help with this because I will to send the phone to Motorola UK next week for them to repair it if my phone temp is not normal
Thanks in advance

i dont even know your temp and i can tell you its normal. if it goes above 70C, cpu temp, then thermal throttle sets in. if it hits 100C, your device will automatically shut down. anything below 40C is normal when not being used. anything below 100C is normal when being used. it will all depend how hard you are pushing your cpu. the harder you push it, the higher the temps will go.
there isnt a normal temp that it should be at, when in deep sleep, when being used, and when being used hard. there are too many variables to answer that correctly. so, there is no standard temp that it should be at.

I didn't need a standard temps I'm just asking to know if my temps are normal because my phone can get really hot with really simple tasks such as surfing the internet I'm talking about 50+ for the CPU which we can say that can be normal since I live in tropical country but what is not normal is the battery temepreture which most of the time above 38 to 43 and that makes the phone hot when I'm holding it

50+ is normal. and your body temp is 37C, so your battery temp is not hot at all, but normal. your phone will shut down automatically if your battery temp reaches 60C(to cool off). the only way ive seen it reach that warm was with playing cpu intensive games while charging or by streaming a movie while charging.

samsung sets up their cpu much differently than how google does. the note 4 also has the same sized battery as the n6, but its battery lasts longer on average. google also adds in a cpu temp throttle, where samsung doesnt. and the cpu is completely different anyways.

Sorry to dig up an old thread but I wanted to mention a problem with the app you mentioned:
It turns out that app you mentioned: cpu temperature is actually only reporting battery temperature! (I confirmed by observing that the single reported temperature matched my phones battery temperature and was far less than any of the four cpu temperatures reported by cpu-z).
I am curious if anyone knows of an app that will provide a trend of cpu temperature(s) over time, rather than displaying only the present-time cpu temperatures like cpu-z
