So I am not sure why my phone heats up so much and so quickly. I don't really use it that much either. Before, I had sky note and sometimes beanstalk roms on but it never got hot even when playing games. Now with devil kernel and dual boot of carbon rom and sky note, it gets quite hot on the top area where the ear piece is. Any ideas what causing the abnormal heat up? (already checked the cpu usage and it is barely in the 1600 mhz zone. Mainly deep sleep.)

Could be rom or kernel. I would try different kernal first. If not try different rom. I had that issue with one rom. Switched and everything is all good now.

Sadly I tried different roms and no use. I'm guessing it's rom but then this rom is the only dual boot one

so then what should i do?
Flash a stock rom. ...And test it...
If the heat goes away. ..you'll know. ..
If the heat remains. ..then it could be hardware damage. ..
But either way. .do it sooner, rather than later. ..

Is something driving up your CPU usage? The fastest way to check that might be to see what's draining your phone's battery using the usual methods.

I had same problem. For me the fix was getting LeanKernel 2.0.
4 hrs screen on time! Its the best for my phone. Since all kernels are device specific it might not be best for you.
To get it go to T-Mobile gs3 go to original dev and download lean kernel 2.0. Make sure its 2.0.
T-Mobile and AT&T work the same. If you use one of the other 4.2 ROMs on here I think Liquid smooth it comes with Lean kernel pre installed.

If that kernel doesnt work for you, you can always try Ktoonsez kernel here:

But for me personally, his kernel and the stock kernel that comes with Task's ROM always make my phone hot and battery drains faster. But many people report those kernels work great for them.

No no. Like it would randomly change the setting to 1.9/1.8 ghz max. Sometimes it would set the max to 1.1 ghz. I donno, it was weird. Maybe that's your problem, maybe not. Every phone is different.

The same thing happens to me. It's not really hot, it's just kind of warm. It only happens when I'm using the phone, when it's locked it sleeps just fine and keeps cool. Otherwise it heats up and drains my battery in the process. CPU Spy shows my clock speed switches between 384Mhz and 1.5 Ghz depending on what I'm doing. My CPU usage isn't consistently high, even if its at 10% it still does it, seems quite normal. I can turn off data, wifi, bluetooth, and location services, doesn't help at all. I've tried resetting my battery stats, where I charged to 100%, cleared stats, depleted fully, then charged too 100% fully. No different. The heat comes from the bottom of the phone, maybe closer to the right side about an inch from the bottom, it is not coming from the battery. My battery usage shows high usage on the Media process or the Android System process. Ending either of them does not help, so I'm assuming they aren't actually using the battery like it says they are.
I'm running Liquid Smooth 4.2 beta 2, same as OP, with leankernel 2.2. It does the same thing with KT kernel, I've tried undervolting but it persists. I've also had this issue running slimbean, Liquidsmooth RC8, and RC9. My battery was pretty good when I used to run stock, and it was absolutely amazing when I ran LiquidSmooth RC3 and RC5.
I have tried both jedi xp-8 and cleanrom 4.0.5 and also clean room with Perseus kernel and no matter what, I keep having performance issues that are most noticeable in gaming and benchmarking. No matter what, my phone is limited to around 40fps or 14000 in antutu. Even overclocking to 1800 it does not do any better.
Update: occasionally when I first restart the phone I will have normal performance but then it goes away.

I noticed this issue last night while watching a high FPS movie on my note. But the FPS counter didn't slow down until i hit 15% battery with the screen at full brightness which is what I always keep it at. Other than that I get really good FPS performance.

It depends on what you're doing. Of course using alot of apps or playing games will cause the cpu to run at full speed. Its going to get warm.

Its a known issue on the GS3.
Don't worry about it too much.
The processor is made to handle heat, and it doesn't come close to failing from heat.
If it really bugs you, you can always try a custom kernel and undervolt and under clock to see how it runs.
My GS3 runs extremely hot playing games, (Real Racing 3 to be exact, and it ran so hot I honestly thought the motherboard would start melting lol) I flashed a custom kernel, undervolted and it runs much much cooler now.
But yeah don't worry about it too much
It was made for that

My friends S3 used to get really hot and he wasn't rooted. I turned off his location service and no more heat. I presume the heat is coming from something that's running in the background. What rooting method are you using? Also you said you've tried ROMs and kernels. Is the heat coming from rooted stock or only when you switch to another ROM and/or kernel?

that's what it's supposed to do. part of the "project butter" tweaks for jelly bean included this type of CPU jump when performing a task. that instant jolt to the maximum device GHz helps make doing everything on the phone more fluid/fast.
to get better battery on your device and troubleshoot whether this feature is hurting you specifically more than helping, feel free to adjust your max speed. start low, at say 1GHz, then bump it up a hundred at a time to find out where your phone is the most comfortable.

Can we maybe explain it as having a device that just run's hot ? It was my first inclination.
OP, maybe I glanced over it at first but you stated you have used many rom's and kernels and got the exact same response on all the ones you used ?
Did you you try going back to stock rooted and seeing how it was from there ? A completely clean slate might be your best idea. The only way a device will get hot is is more power is being used to keep the processor at higher temperatures. There really isn't any other way or than faulty hardware issue.

its not a price tag. its a script set to take advantage and make the most of the hardware on your phone. as soon as the task has begun, the CPU speed drops immediately.

I almost always use ondemand governor. In my humble opinion nearly all the other ones are inefficient or just placebo's. My phone runs streaming radio 4-5 hours a days on LTE and it never gets hot. Stays at around 918mhz at the highest. There a few bugs in 4.1.1 like the media server scanning where it will constantly scan your media because of a bad file.
Odin stock rooted 4.1.1 and then see how it goes. Factory reset it and erase /data or move to to pc or ex sd card. Won't take long and if it still does it I can't see what it would be.
Hi my note 2 is supper laggy i already rooted it over clocked it , i tried to odin back to stock and still laggy as hell might this just be a defective unit ? Even playing a youtube video there is lag. Anyone help ? thanks

That seems kinda low for an overclock gn2. What ROM are you running? If you are custom right now try stock without any mods to it and see what you get. You also may want to try and undervolt it. Also check what CPU settings you are running using setcpu or nofrills. Change the setting to performance and see if that helps.

If it were me, I'd focus on getting my imei back and starting with a fully functional phone. Playing with unsupported (for our device) roms (such as the TW 4.3) or modems is a typical way to lose the imei. I am referring to the other request for support thread you posted.
Lag sucks. Not being able to use your phone as a phone is worse. Focus on one problem at a time.

Given the status of my phone. Being on custom clean rom didnt really need to OC or anything. OC tends to make my note 2 unstable and bring the battery life down a little. Think the cons out weighs the pros really.
