Anyone experience this? I noticed when my phone is plugged in and i play a game for 5 mins the top half of my phone gets to 47-48 degrees... Almost too hot to hold. When I leave it alone it stays about 10 degrees cooler. Anyone know what might be causing this?

Not sure what might be causing it but mine does the same. It's probably normal.
There are several threads discussing this. Please search first.

The current to your phone and the addition of you doing something causes the processor to get hot. That's it.
Are you using the flip case from Samsung?

I didnt do anything to the phone.. This was a replacement from my original one that was randomly rebooting and freezing.. Im just worried i might damage the internals.. Anyways i called rogers for another replacement. They are sending it as soon as i return my original

Thanks for bringing this up, it's quite relevant to my interests.
Mine also gets hot. I recently upgraded my folks' phones to ATT Galaxy S II's (non Skyrocket) and they both get very hot when surfing on battery power via data. My battery monitor widget said 103'F at one point.
My Note also feels a little laggy (not hugely so) and has crashed a couple of times. The battery life is atrocious (coming from an iPhone 4)... I'm considering exchanging it at ATT as I'm still well within my 30 days. Rooting and freezing all the usual suspect apps hasn't helped.

Whats weird is that my original one didnt get hot but was laggy and freezing up. This ones the exact opposite.. Fast as hell and hot. Now i did a couple tests and the only difference was that the white on my current phone had a slight yellowish tint on the original. Battery life i get 12-17 hours on both.

On a sidenote just took my phone out of my pocket and while writing the last post phone got to 37 degrees and this is while it was off the charger... Anyways once Rogers recieves my original note they will send me a replacement to my replacement lol.. Anyone know if i get three lemons would I be entitled to a new unit? I know carriers used to do that.

My first note would her extremely hot between 117f and 130f while idle on a charger from the top half up. Used a thermal temp sensor from my liquid cooling to measure temp. According to a friend of mine manager at an att, said the heat problem is the biggest for return and that from what he's found out talking a Sammy rep that the cpu and memory in some units through shipping and handling have been loosened from their respective heat transfer system.
So basically manufacture defect and if it gets hot replace it. It'll hurt the internals.

feel bad for the ones having all the problems.....its hard for me to get my phone to even reach 40C and thats while watching movies and pausing and making calls. the playing a game. i have to do ALOT to get it that hot.
i have noticed the pocket thing though, if i keep it in my jacket pocket it seem to get hotter faster even though i am not doing anything on it at all. but it goes right back down again after i pull it out for about 3 min.

I'm wondering if I have ANOTHER bad S3. First one never heated up at the bottom but had a bad volume rocker that didn't work. Got it replaced and now this one always gets hot at the bottom. My usage hasn't changed... I'm wondering, is this normal.

I just got my phone yesterday so I haven't really had time to use it. However, when I was downloading all of my apps from the Play Store, I did think it was very hot on the bottom half of the back.
That being said, I'm going to go to the store tonight to get my phone replaced due to loose/clicky home button.
Mine only gets hot at the bottom when playing intensive games like Dead Trigger on max, which seems normal. If it is getting hot all the time on normal use that doesn't seem very normal.
Mine gets hot at the bottom with normal use. :-(
warm at the bottom with normal use. nature of the beast. slim, high powered phone, its gonna get hot
Mine gets warm sometimes on its own with the screen off and everything just sitting in my pocket. Without playing very graphically intensive games though, it won't get what I consider hot. At least coming from my old DINC.

Things like this are a big reason why I'm very hesitant to exchange my phone even though it has problems. You might always end up with one that has worse problems than the first one you had.

yeah mine gets slightly warm at bottom under light to moderate use. doesnt really bother me at all.
It's a powerhouse phone that's so slim of course you're going to feel the heat. If anyone thinks they have a problem with their phone download "Cool Tools" and you can check the temperature live.
I know during easy use like sending a text the phone is cool.
Moderate use like surfing the web or watching a video the bottom half gets warm.
Heavy use such as playing Dead Trigger or Nova will cause it to get hot. But just like any electronic device the more use the hotter the temp. Sadly phones unlike desktop PC's don't have cooling fans.
WARM/HOT IS OKAY! STOP FREAKING OUT PEOPLE!
Mine has only ever gotten slightly warm at the bottom, and never hot or noticable. That was while constantly dropping in/out of service and heavy usage. Other than that it has been very cool, even when charging.
Also those with a case will feel the heat differently as well.. If you have a case you're less likely to notice the heat.
Those without a case will feel the effect more.
Either way too many of you freak out over nothing.
I think this is funny because when the new ipad came out (which i love btw) everyone was writing articles left and right all over the internet about it getting hot.
It's normal for it to get warm/slightly hot especially when using it while it's charging. But really anything after a few minutes of use will make it begin to warm up. Then toss in videos or games and it will warm up some more. As phones get more powerful and thinner the more we will feel the heat. I mean these are miniature computers but unlike laptops or desktops they don't have the luxury of a fan and ventilation system. The heat has to go somewhere right? Every dual core phone i've used gets warm. My Sensation actually gets extremely hot (HTC said it was normal), and my Bionic gets pretty darn hot too.
I returned mine because it was getting extremely hot after only 5 mins of lite web browsing. Back to my S2 or Gnex I guess.
I hear what you guys are saying, but my first one didn't get warm. I don't do any intense gaming or watch videos. I use the Facebook app, instagram, I text and make a few phone calls. The second one gets warm and the first one disnt... Same usage

Got mine yesterday, noticed that it also gets warm on the bottom.
Have one of those belkin cases that covers the rim but leaves the back exposed, so I definitively notice it.
However, as some have said, wouldn't worry to much about it.
OP, do you have the exact same settings as in your old one? Mainly motion actions, Svoice listening for wakeup command all the time, etc?

Got my Note 2 about 2 weeks or so ago and like it so far. However, I notice it runs pretty warm consistently. Using system tuner, the temp is upper 40s°C Most of the time. And this is just sitting in my pocket, not gaming or anything intensive. Anybody experience this? The screen is pretty warm and is even uncomfortable to hold to my ear. Any help is appreciated. I did look and didn't find too many threads about it with the Note 2, and apologize if I missed any. Thanks!

Man, I hope that doesnt mean something is wrong with the phone. I just restarted it and I immediately started feeling heat from the screen when it turned on. Are there any ways to see if an app or something is the cause rather than hardware, etc? I'm trying to keep an eye on any apps I downloaded and might reset the phone as a next step...

Your device probably has a lack of thermal paste on the motherboard or they didn't put enough past in between the display.

Have you run any benchmarks? If there is an issue then it won't be good for the phone, but it'll tell you if it's throttling from heat issues. You also may be able to trade it at verizon with just the heat issue since it's noticeable so fast, but I'm not sure..
Ran a benchmark and everything seemed fine for that test. I'm resetting it now and will see if that makes a difference. I'm just past the two weeks and know I'd probably get a refurbished if I went to exchange it now. Everything else is working fine, so if this can be figured out then I'd much prefer to keep this one. Thanks for the advice guys. If anyone else knows something else to check before I possibly exchange it, that'd be great!

We have the same issue.. First install the android tuner, remember that the battery temp is not the same as the CPU temp.
I have my note that sits 38-42 CPU temp when Idle and 28-32 battery temp.
When I am browsing I could really feel the heat on the upper part of the screen. my CPU temp rise to 47-50 and my battery temp rises to 32-34.
Check your note.
I was browsing rhrough the forums and saw that you had the same problem too. My CPU temp is about 42C idle and goes up to 50 or just over when doing pretty much anything. My battery is about 33C at idle

Ill check in a little while. I tried resetting it and it was doing better at first but doing the same thing again. Easily going over 50C if I'm just in the camera for about 30 seconds and most ither apps. Might just exchange it, even if I get a refurb, and take my chances

Turns out it was an app or two causing it. I think one culprit was running wallpapers through picspeed instead of saving them first. Lesson learned and still monitoring cpu and battery usage. It's now running normal temps (low 30s even 28-29 sometimes when I first wake the screen). Thanks for the advice!

So the past couple of nights I have been using sleep as android to track my sleep patterns. Worked well every night until last. I waited for the screen to turn off than put half the phone under my pillow to keep it from falling off the bed. This morning I went to go turn off the App and my phone was burning hot. It was showing a black screen. I could not even hold the phone in my hand it was so hot. I have auto screen off enabled for 1 minute.
I waited about 20 mins and the phone finally booted up., it would just display the LG logo real quick and sit at black screen Untill it cooled off.
My questions are is this because it was under my pillow charging? I know this phone has a temp sensor, but can't find a temp sensor that work's. I know this because if I have the screen at full brightness after a while playing a game the screen will dim, ill go into settings and try to bump it up and it says temp to high please try again later. So I know this phone has some sort of safe guards. How come my phone was burning hot, shouldn't it have turned itself off. Also can this happen even not being under my pillow? Im nervous about leaving my phone chargeing when I sleep for fear its going to burst into flames lol.
Just curious if anyone has ever had this phone get so hot you could not hold it? Phone seems to be working fine, is there away to make sure this phone never gets that hot again?

Best guess is, yes. Don't put your phone under your pillow. The beat has nowhere to go basically it just keeps around the phone.

Check your battery, it may be three cause for this problem. The battery is what heats up the phone the most, if it is leaking, or damaged in any way then it can cause this
Also try cleaning any vents on your phone, they may be clogged, not allowing dissipation of heat
Alternatively, check which kernel and cpu governor you are using, if it is terribly inefficient it can be causing the cpu to stay at high frequencies, which can cause it to increase its TDP footprint

I have to be honest with you guys. The only time my phone gets hot is when I play intense games or download a 200+ MB file. Other than that it's always cool, and I'm using a case.
Don't leave your phone under a pillow, turn it off when you can, try and use darker colors/lower the screen brightness as much as possible, and give it a break every so often...

You could check the battery by sending it to lg, or check for any sort of liquid seeping from the phone. As for the governor, try setting it to a more conservative setting, on demand can result in it pulling max resources all the time and this can cause the heating. Apart from that, don't keep it under a pillow, in a leather case, or in tight jeans. Keeping it in the sun in a car can also be problematic

Mine got super hot when I first got it. It would do it randomly on occasion, but normally in recovery, however over time (and after flashing updated recoveries) I've been noticing less and less of a problem. Using sk8's kernel also seemed to help.

Have had same problem w- sleep as android app also
At first I thought it was from being under the pillow as well. So I made sure not to put it there the next night, but had it on the bed. It still got pretty hot, just not as hot.
Next, I let the app run all night next to me on the nightstand and it still got pretty warm, but then you don't reliable stats. I then made sure the app was off for a couple of nights and the phone was at a normal temp in the mornings.
There is definitely something different with my phone when running this particular app.

Today my stock phone with JB overheated. I got a message on the screen that said the phone was shutting down for my protection. I was in the process of installing apps from the Play store. Six hours later it will still not turn back on. My battery was around 25% or so.
If it is not plugged in then no combination of button presses will produce any result.
If it is plugged in then it boots to the first logo flash and then reboots.
If it is plugged in and I boot to download mode then it flashes the download mode screen and reboots.
If it is plugged in and I hold down the power button then the power button flashes rapidly.
I left off for a couple hours and then plugged it in for a couple hours just in case it did need to charge, but it did not produce any change in results.
I am fairly certain that the fix described in http://forum.xda-developers.com/showthread.php?t=2039707 will work. I can also just return my phone since it is only one day old.
However it looks like there might be a fair number of people having this issue so I would like to look into preventative measures so that it does not have to happen. Other than not using the phone if it starts to get hot, does anyone have any ideas of where to check? Are there any files that can be changed to help the phone not get stuck in the pre-boot phase? I know we can change the temp that the phone shuts down at, but given that my phone actually was pretty hot I doubt that is a good solution.
Get a new phone and immediately turn on eco mode. My phone has never gotten hot during heavy usage and you won't notice any difference performance wise. You may notice better battery life, although, I haven't seen much improvement.

That is what I did with my first phone (I have two). I didn't on this phone because I wanted to see if there was any performance difference I could notice. It didn't seem any faster, but I only got to use it about 45 minutes before it overheated.
I will most likely return it, but I really do want to see what I can do to help out the people that won't have that option. I like fixing things so it is a hard choice.

This one. I sat and stared at my screen for 15 minutes trying to decide the best and shortest way to word that. I guess I failed.
I ended up returning my phone. I turned on Eco mode as soon as I could as was suggested. I noticed my phone was starting to get just as hot as before so I double checked and Eco mode had turned off. I am keeping an eye on it, but I have still had it get pretty hot a couple times. Mostly when I am downloading a lot and have the screen on. I'm staying safe by not using it for long periods of time, but that is going to get old pretty quick )= If it is a bad batch thing I suppose it would make sense that this one is bad too since I got it from the same store just two days apart.
I scared to see what is going to happen when I use LTE for the first time tomorrow lol.
