If you are having issues you need to post more info. Rom? Kernel? Certain apps can cause issues. If you need help ask. Posting a rumor by a "MIT" kid is not overly impressive to me. Egg heads over think things sometimes.

RG2X with Faux .47 and on .48 kernal. I am getting exactly what the IT guy described. Overheating during deep sleep while on charger. Non-OC'd with nothing major running in the background. Not even Setcpu or Juice Defender. I will assume this guy isn't on RG2X's rom nor on a MIUI rom. Maybe on Faux but I think it would be better to assume he is probably on 2.3.3/4 stock. Also he stated it was on two different phones that he did both of these tests we can assume it's not a rare thing. Noted it's not with every phone this happens but some for sure are getting dead phones upon wake. Because they die probably about half way during sleep by the time the person wakes up they only notice a dead phone that needs a battery pull. The heat is already gone so they wont notice the over heating. I actually felt my phone overheat on the charger so I can tell you what this guy is saying has some weight to it.
I shouldn't assume I should just read "We both a running stock lg g2x gingerbreads and have not tested it on any other roms"

If (big if) the overheating observed is due to heat from the battery charging leaching into the phone, wouldn't a quick and easy fix/test be a piece of aluminum foil between the battery and the phone?

I have no problems at all. Running CM7 Latest Kang / Faux .48 CM battery. The last few versions of Faux's kernel fixed the SOD. I have never done an exchange. I got my G2X the 1st week it was out. I have never had any problems at all once the phone was rooted. Only thing I have problems with is the screen bleed. I am not OCed at all just UVed. When the phone screen is off setcpu sets the cpu at 389min 503 max. I have no overheating problems. So if you have overheating I would say that your phone is broke, you need to lower the OC if you are OCing, or you have done something wrong with the software.

Thanks for the report captain obvious.
I am glad your setup is fine. For those that are in stock configuration and non oc'ed yet experience these problems, they have probably come to realize that there is no support from tmobile or LG.
If the words "restart " or "shut down " during your tech support convo, you will be told to suck it up and wait for a software update. An update which will probably not come considering how many months has passed.

No problems at all here with overheating or SOD. I have over 200 apps installed. And yes, I'm seriously still running stock Froyo.
The only problems I've had are sluggishness and freezing after disconnecting the USB (both computer and wall chargers.) I think it's an automatic sync thing, or possibly something reading my 10GB of music files on the SD.
Got mine the first week out too, but from Amazon.

I don't think anyone is saying this problem effects everyone. It's just with all the bad units out there with this problem, this is probably why it's happening. Right now I'm trying to run some profiles in setcpu to see if it improves my phones sleep. It's only been one day so I will see by the end of the week how this fares

Posts like this post is the reason why the devs hate the G2X. Most if not all problems most of the time are with android. If you are not using setcpu to control the cpu by setting up profiles for screen on and off. Then you are missing out on what root gives you access to. My phone might have the same problem yours have with overheating but i will never see if because my phone is UVed and runs at a lower CPU speed when the screen is off. If you want to use my setcpu profile look at my last post.

The overheating is not a Android problem it's a LG doesn't know how to product test problem. All my other Android devices didn't have this problem. One did have an SOD problem that was fixed but I never had to deal with overheating. This is on LG not Google.

I think the term overheating is thrown around too loosely here without more of a description. There's the type of overheating that causes our phones to shut off and stay off until the battery is pulled. There is also the type of overheating that occurs when you plug in an HDMI cable, which may or may not cause your device to die.
I'd assume those two types of overheating are the same, as they result in the same thing: dead device that won't turn on without a battery pull. And the phone gets hot as fsck. Hot as in you'd be scared to keep it in your pocket because (1) it'll burn your leg and (2) you are scared the battery will explode.
Those two types are overheating are different from your phone merely heating up upon use. I'm talking about charging the phone while navigating via GPS at full brightness or playing a graphically intense gaming. That magnitude of that heat is normal. And I'm guessing that's what all your devices have experienced.
And as all the devices get thinner, that battery's going to sit closer and closer to your hand, which equals more heat. And as the glass technology gets thinner (gorilla glass 2.0), your face will probably feel the heat to a greater degree as well.

It's true, it's not android, it's LG.
And to all the people thinking that undervolting and underclocking your phone will fix everything, it won't. Android already underclocks the CPU when it's not in use. SetCPU does nothing in this instance. The only instance they'll see a difference is if they have some sort of rogue app that's maintaining a wake lock. You just can't beat terrible design (referring to the MIT guy's findings). Sometimes it'll work, sometimes you just lose.
LG majorly screwed up with this and I hope that their mobile efforts in the future fail for their lack of follow through.

I think I've avoided the charging SOD by accident....
I don't like the official LG charger since it uses a microUSB cable which I'd rather have as a spare on my computer..... so most of my charging is done with an old charger I just had laying around, which turns out to be 0.7a instead of 1.0a which the LG charger is, or on USB which goes through about 3 different hubs so probably has little power left by the time it gets to the phone.
Sure, charging is a bit slower, but that probably prevents some of the overheating.
Lesson: If you're having overheating during charging, dig through all your old chargers and find one with a lower output rating. Use the higher output ones only if you're in a hurry to charge.

Just wanted to say that this thread has been really helpful to me. Every time I've flashed a custom kernel, my phone has always, within the first 2 nights of installation, turned off in the middle of the night while on the charger. So I've always been stuck with the stock kernel. But then the suggestion to use SetCPU to lower the speed while the screen is turned off worked for me. So far no SOD and my phone has survived Faux's kernel and charging overnight without a battery pull and without overheating.
Now I can try out custom kernels and find all new ways to destroy my battery by doing things I'm not knowledgable enough to be doing!

hmm.. I dont doubt you, but I think doing that would not be any different.
BECAUSE, the charger is not constantly charging at 1A rate. If you notice, the phones ramps down the input current after a certain percentage ~90%, and trickles it up to 100. Once at 100, the charging is supposed to be stopped. I've charged mine with my bluetooth 500ma charger, and I didnt see a difference in heat temps; only charging time took longer.
As far as heat, Lion batteries should be able to handle 1C charge (1 x charge capacity) with no problems in heat. That means even at 1.5A charge, it should be OK.

Regarding overclocking, undervolting and overheating. There is a variation of parameters across every silicon wafer; among the 25 or so wafers in a wafer lot; and from wafer lot to wafer lot. This is referred to as the "spread" and parts at the extremes are called "corner parts". Most parts should be in the middle of things, not all. With newer parts and small silicon process geometries, the margins are typically smaller - hopefully improving as the fab gets experience with the new process.
A hardware developer should get corner parts to check their PCBA layout and FW, to see if they have design margin. In the case of DDR (RAM), the voltage, circuit layout and DDR interface timing (from Tegra, in this case) should be checked across some tolerance and with the corner parts. "Fast" parts can draw more current during operation that nominal parts, possible heating up the voltage regulators nearby.
In a good hardware design, everything should work across part variation and the specified operating temperature for the system. When we start playing with the clocking frequency and voltages, there is the risk of FW crashing and HW flipping out. The symptoms can include system shut down (lost), resets, heating, bad effects on other systems (battery, voltage regulator circuits, etc.).
This is why some of us (like me) have little luck Set CPU and others can change it to extreme. What none of us know is how close to the design limits the G2X is - the system and the components like Tegra, the FW control. If due design diligence was not done, the sensitivity to part variation and our hacking is greater than normal.

During use, phone heats up to 41c/104f regularly.. this cant be normal?

Just web browsing over 3g for 20-30 min will heat the phone up pretty warm to the.touch. it also drains about 1% per 1 min of 3g browsing not even streaming. I'm still on 1.73 att. No apps in background and there is no idle battery drain. Is this normal? I'm guessing not brightness is set way under half

This happened to me only when I'm on like YouTube for a while but mine reaches like 110° F :-(
Sent from my HTC One X using XDA

mine gets hot as well just by browsing. it is right on the bottom left of where the camera is

If I just check FB or draw something, this phone will start searing my thigh when I put it back in my pocket. This phone is definitely HOT(not in a good way...)

I have had 0 heat issues (can only feel it heat up while charging)
Maybe this is because I had the iPad 3, so nothing seems hot in comparison

mine only heats up when im charging and using it at the same time (playing games usually)

Maybe someone should make a poll because I'm having zero heat issues. Played few games the other day while waiting for my gf's OBGYN doctor to come in and check out our soon to be baby and we was playing for a good half hour. Barely any heat at all. Charging produces hardly any heat if any heat at all (noticeably anyways).

The highest I've seen so far was 41C while using wifi tether. Since I came from Nitro HD, which goes to 63C when voice talk on skype or gtalk, and makes your brain boil, this didn't bother me a bit...

Mine only gets hot when I use google navigation, which is understandable. It gets warm when I play hanging with friends, but in my experience that game spikes the processor the entire time it's open.
Sent from my HTC One X using xda premium

No heat issues at all for me, I tried to put as much load on the phone as I could to test this issue and all is well, it got warm to the touch but no more than any other smartphone I've used in the last ~6 years...

41c is not hot. My Atrix used to rocket up to 60-70. That was too hot. Think about it: 104 is barely warm enough for a hot tub. You can run a fever of 104 and be ok. Yeah, it's high for a person, but come on - dual 1.5ghz with a HD screen? They can't make that stuff make cold instead of heat!! Just saying...
It stays well under 50c. In my mind... *perfect*

I am coming from an LG Thrive and using GPS never got as hot as this phone or got hot as fast either. The only time it did get hot was if the sun shined right on it. I put my screen to never shut off and run google maps so that it would update to latitude. The HOX definitely gets very hot on a cloudy day when my Thrive would be just warm if that

Just so we're clear, good build quality will often make the exterior of a device hotter. This helps keep the all-important interior cooler. Having my phone feel hot while being measurably at reasonable temperatures is good! You must be careful not to base your opinion of the device's thermal management on subjective senses rather than measured fact.

And I won't argue the subjective notion of heat on your lap during nav! I know 105-110 feels pretty doggone warm (I had to check the temp to make sure it wasn't overheating), but if the exterior is only a couple degrees different than the interior...? That's good stuff right there.

My phone does seem warm to me now that i think about it but it seems to happen when it wants..
yesterday i noticed it would get pretty warm (not ridiculously hot though) when i would be on it for a few minutes (texting, tweeting, the usual).
but then today it was just fine. it was warm but not like it was yesterday.
not sure if i'm just not used to having a phone with this type of casing, (i had an Inspire previously and it didn't seem to get too hot.) i would figure a phone with a plastic or similar material casing would feel warmer compared to something like with a metal back (correct me if i'm wrong )

I don't think that this phone should get hot. It uses a 28nm process while being just a dual core processor. I think that the voltage might be higher than it should be. We need custom kernels and roms for this baby!!!

NOT a known issue. The S III might get warm under a heavy load or charging a very low battery, but overheating? I'd look at the mods you've done to the phone. The ROM you flashed, the apps you're running... this sounds like a user error.

Roms?
I have cyanogenmod 10 nightly with jellybean 4.1.1 and I've been getting temperatures around 95-101 fahrenheit under pretty heavy use. From what I've found out, it seems normal.

If your in the 140 degree area, start investigating, if your 150+ start worrying. Other than that, don't worry about it.

You realize that your PC likely has rather decent ventilation and actively controlled fans, yes?
120 F isn't really a cause for concern, IMHO. Above 140F consistently might be, though - could be the battery, actually.

The 4g is one of the biggest culprits for heat. My phone heats right up if I'm tethering or downloading directly. And I imagine there's a lots of back and forth data with Twitter along with the other browsing he mentioned.

Those temps are fine. If I have my phone plugged in and tethering I've seen low 150s. I usually try to cool it down at that point but just so it won't go higher. I've been told that 160f shouldn't hurt it.

Awesome! Thanks! My old laptop would often get up to almost 200, in fact it would idle around 180, but I was pretty sure the phones would withstand far less due to the fact that it is in a much smaller package and that there is no heatsink, I just wasn't sure how high it can go.

A CPU is a CPU pretty much. The heatsink just helps keep the temp down. Equivalent of taking the back of our phone and putting a fan on it almost.

Critical temp is around 180. Our phones will automatically shut down

I had my phone get quite hot the other day after I switched to cleanrom 6.5 and now the phone doesn't want to take a charge like it did before. Could that be some indication of some damage done?
I didn't have the frame of mind to check the temp at the time. It was noticeable hot though. Even through the case.

I would advise against that. at the very least use room temp water, not cold. sudden temp changes are never good. could induce cracking in the glass or other components

[Q] Is it normal for Nexus S to get hot in Hot Temperatures??

The temperature in my city is around 40°C.. But real-feel is around 42°C...Summer has just started and my phone is getting hotter than usual... However, the phone is not so hot in idle mode... Its around 31-33°C.. However, after playing few games or browsing for around 20-25 mins, my nexus s is getting hotter and hotter.. I can feel it in my hands... But still, the battery temp is showing 36-37°C only... I've never even seen 38°C on my phone... But still, I can feel the touchscreen is getting very very hot...
After opening the back cover, I began examining myself.. I noted:
The battery is not that hot
The sim area is very hot (I even started my phone without the SIM card, but same result)
The area beneath the camera and flash is also too hot..
The touchscreen itself is getting v.v hottttt.... I cannot play touch games anymore... However, the lower part of the touchscreen is absolutely normal...
When charging, the temperature doesn't goes more than 35°C... However, I can feel the back side is warmer...
2months ago, when the temp was around 30-32°C, I've never had this problem Everything was fine and running perfectly... Still now, everything runs smoothly without lags
I've never heard that touchscreen is hott... I've had many phones and my city's temp remains mild mostly... So, what could be the problem?
I am using:
Carbon unofficial
Marmite 8.5cm_bigmen
No over/under clocking
Vooodoo sound with +5db (Hardware highest)
Ondemand with cfq
Battery timings: 1.5day with normal use (4-5hrs of screen time)
1day with heavy use (6-7hrs of screen time)
Should I revert back to stock ROM?
Is there any IC problem?
Battery problem?
Processor problem?
Or is it normal for the phone to get hot in hot temperatures (42°C)???
Should I see a doctor?

Its normal dude. If you want to keep it cooler than don't keep the brightness too high.
One thing that can REALLY heat up my phone is playing games at 100% brightness on a hot day so try to avoid that.

Oh Thanks man... I was really really worried...

No dude the same areas as you describe are the ones that can get really hot on my phone.

My i9023 gets really hot if i play games at max brightness, so now I avoid playing games.
And yes, it also gets hot in the processor area, not the battery.

Now, my phone is getting very hot while playing Asphalt 6 or even Fruit Ninja... Only the processor side (Top portion of touchscreen and its back portion) is getting hot... Battery is definitely cool (Not more than 38degree)...
What could be the problem? My processor has gone mad or what? I've even tried undervolting as well as processing speed to 800Mhz max... But overheating remains

My phone gets hot only when I'm on full brightness and a game I usually put it at half brightness and it never happens even when playing mc4

This is absolutely true. I have Nexus S since 4 months... There was no problem at all then.. everything normal and running fine and never overheated at all no matter what i play...
This overheating problem started few days back when I tested overclocking and overvolting NS
Seem's this is the problem..
I think I have roasted the processor and it will always remain like that.. I will have to sell it soon now

is it still over heating on half brightness?

It is... I am on 3% brightness...
Should I give a try to a new OEM battery?
Will it resolve the overheat issue?
Why is the processor heating up too quickly? Has I finished its life by overcloking it? Or it is a battery issue?

I went to the local market for some inspection of my phone. The person said that your phone is not giving maximum current and the charging ic is getting very hot and has to be changed... How is this possible? I've never had any problem with my phone like this... 100% charging was always OK for me
