Anyone else experiencing heat?

So, I've had my phone in my pocket for the last 30 minutes or so while listening to a podcast (not streamed, one that was downloaded) and I pulled the phone out and it was fairly warm. Nothing else going on with the phone besides the gmail sync, no downloads, no wifi, nada.
Anyone else seeing this as well, or do I potentially have a bad battery?

Mine gets a bit warm during charging, but not during usage i've experienced yet - but I haven't done heavy 4G data yet, only wifi and light 4G
Though to see it with no data usage is somewhat weirder.

I noticed with some heavy usage mine gets warm

um, your leg is typically warmer than your hand.
I notice my phones are usually warmer right out of my pocket.
or maybe i just have hot pants. BA DUM, CHING!

Mine gets warm as well with usage.

yes, when using my charger it heats up and after playing select games it heats up. Farm,city, and bakery story all make my phone heat up.
never when i'm not on the charger no matter if i am on wifi or 4g though.

I had the Zagg invisishield on mine melt and bubble last week while using GPS navigation for a few hours.

I noticed the exact same thing today. I had flashed das BAMF 3.0 RC2 the night before, followed by the newest dream kernel 2.2.2, and noticed battery was diminishing very quickly (could just be coincidence - not saying it had anything to do with ROM or kernel). Then I noticed the battery was getting very warm - something that has never happened to me, even with heavy duty use.
No idea what it was, but I ran out of battery pretty quick and just turned the phone off. Flashed imo's lean kernel when I got home to see if I could save battery.

I've definitely noticed when it's warm, the battery drains extremely fast. I'm surprised how hot it can get...using extended 2750 battery.

Thunderbolt definitely has a heat issue. My phone overheats when used in official ThunderBolt Window Mount for navigation. I have Tasker produce a voice alert when this happens. This makes ThunderBolt pretty much unusable for any long distance navigation, something my old Treo did well. It is probably combination of charging and rather mild San Francisco sun shining on the phone. Anyone from Texas had their phone explode yet?

What's odd is that when I'm on 4G at my office, and put my phone on the charger, there's no issue. When I'm on wifi at home and I charge my phone gets very warm; so bad in fact, that I get an inevitable reboot from overtemp. I'm having trouble diagnosing what could be causing this issue.
This is on a stock unrooted phone with MR2.

i was in Texas when my original droid got up to 170 degrees. i was sleeping with pandora playing, so it was probably that hot for several hours.. it bricked 3 seconds after unlocking it. no explosion or anything it just burned the **** out of my hand.
soooo happy i have the tbolt now!!!!!

[Q] G2x Shutting Down Possible Causes?

What might be the possible causes to the T-Mobile G2x randomly shutting off by itself?

POS
Mine crashes every night and needs booted in the morning.
It's the best phone ever and the worst phone ever.

I think it's caused by loading giant signatures at the bottom of forum posts.

Mine does it randomly. I had it since April 20, and it has shutdown 3 or 4 times. Still don't know the cause of it.

Funny no one is stating their OS they are running?
The only time my phone randomly SHUT DOWN was running the leaked Gingerbread rom from LG. Stock was fine as were CM7.
Of all the roms I've tried, I've never had reboot problems or finding the phone off outside of the leaked GB.

This happened to me all the time with the stock FroYo ROM. I think it is caused when the phone runs out of free RAM (due to playing a game or running lots of widgets) I flashed CM7 with the ext4 Trinity maxmem firmware and it fixed all of these types of problems. Also, the stock battery seems to have major issues because when I replaced the battery with a third party one it fixed lots of problems with battery life and also the HDMI instantly drain the battery.

I still believe it could be a combo of questionable batteries and chargers. Purchased two the first week out. Mine started the reboot dance the first night. My wifes phone has had zero issues as has my replacement.

Probable fix
Hello,
So we’ve been working on this issue for quite a while. And have come up with a semi-practical solution. This might interest some of you, who have this issue.
Issue:
Both I and my friend opted out to purchase the new and wonderful LG g2x phone. After receiving the phones we came against a very similar issue. The cellphone unit would shutdown/turnoff during the charge [car or wall]. The shutdown would occur around 95% of battery charge. In addition the phone would get hot. After the shutdown to start the phone would require pulling the battery out of the unit and reconnecting it again, otherwise known as: Perform a battery pull.
Trials:
So after doing some research and funding out that LG is literally doing nothing about this issue, [great testament to their corporate integrity] we decided to take on this issue. At first we also believed that it is, indeed, the battery that gets heated and goes offline after reaching some temperature. After recognizing the poor quality of the battery, I’ve decided to purchase a better quality one online. No surprise really the phone would still lockup at 95% charge.
At this point I took it upon myself to resolve this issue with what resources I have available. I am an MIT student and have a high tech engineering lab available at my disposal, in addition to some free time with a winter break and all. Anyways, I pulled the phone apart and this is what I’ve discovered…
Discovery:
So inside the phone right next to the 4 connecting diodes that connect the battery to the cellphone unit are 2 semis [semiconductor hubs] that are responsible for providing battery charge information to the cellphones cpu [central processing unit] in addition theres also a line running to those semis that probably carries some sort of information [current] that the semis are also responsible for.
The first approach that we took was through the hardware, and killed that additional line and allowed the semis to only be responsible for the battery charge. The results were somewhat positive. Although the phone would freeze and glitch like crazy it would not shutdown with a subsequent necessity of pulling the battery.
We also noticed that it was the two semis that would get hot actually and lockup shutting the phone up and requiring a battery pull. The reason you need to pull the battery is because the iodes would overheat and completely glitch out, also even though the phone was now powered off there still was a current running between the battery and the phone. Only the battery pull would allow the diodes to drop the charge and reset to the position for the phone to be functional again and able to power up.
Solution:
So the idea was to find a software solution, which would free up this one line running into semis and allow them only to carry the responsibility for reporting the battery charge to the cpu. Believe it or not the first thing that came to my mind was the solution.
The app called Advance Task Killer (ATK) [available free on the market] proved to be useful. I do understand that this program is not very effective and only kills running progs in the foreground. However, that single line is also not very important to information transfer and becomes useless after you clear the cellphone’s foreground information transfer.
Basically when you run atk the line becomes inactive and you can charge the phone without any lockups. I’ve been doing that for about 10 days now. Discharging the battery to about 17% and charging it all the way up again and the phone has not yet turned off once and required a battery pull, nor has it been getting hot.
The idea is to clear the line prior to putting the phone on charge [car or wall]. So what you do is run atk few times [twice at least] then plug the phone in. this worked for both me and my boi here @ mit. After a week plus of testing we decided to release this onto the public.
We both a running stock lg g2x gingerbreads and have not tested it on any other roms, however, I suspect that it will have a similar effect on more leaner and cleaner roms like CS7.
Hope this helps those who are still struggling with this issue.
P.S.
In addition I would like to add that we did pull the battery apart in the lab and found that the stock battery was complete SHAYT! Some of the cells were cracked and overall it was just poorly manufactures. Cracked cells inside the power unit diminish its capacity to carry charge by a factor razed to n^power. Also may cause the battery to heat up during the final stages of its charge process [around 95%] due to the fact that to go the last 5% it will require higher resistance also in n^power. I suspect that in this great economy LG is cutting corners whatever place it can so there’s prolly very minimal quality control in power unit production. To those who think that they lose charge too quickly, that the battery gets too hot during charges, and possibly causing the phone to lock up: If you are using the stock battery, you may want to consider replacing it.
P.P.S.
Overall it is a hardware issue, in our opinion, that could be fixed with the use of the software, by rendering that extra line inactive for example. However, I would like to NOT compliment LG as a corporation and organization in general on their moral standing and responsibility that they carry to their customer base by doing completely nothing about this issue!
Thank You LG, I am no longer your customer.

Mine used to only shut down during phone calls. This only happened about 4 or 5 times and it got very annoying but eventually it just stopped and hasn't happened since.

I had my phone reboot during calls a few times a day after I got it. I OC'd my phone with Setcpu and was running Juicedefender. Ever since I clocked it back down and uninstalled those two apps (mind you I just got rid of them without doing any research if it was a problem really either of them cause). I'm going to get replacement batteries soon in hopes to help but it's good know a technique finally so my phone wont crap out during the night.
Seperate story kinda, I once put my phone on the charger. I placed the phone on my bed but with proper air circulation. It sat there for an hour or so. I walked over to use it and the thing was extremely hot. I pulled the battery and checked the phone. The battery was hotter then the phone so you could tell it was the thing over heating and not the phone. I put the battery back in the phone and booted and went straight to spare part's battery stats. It said the battery was overheating. So I pulled the battery and held it and the phone in front of a fan. 5 minutes later it was running cooler then any other time I looked at the battery readings (about 28c) and my phone charged fine for the rest of the night. Also yes when it did over heat the phone wouldn't turn on the first time I got to it.

Severe overheating?

Hey guys,
This last week has been absolutely brutal in the northeast us. We've had high 90s pretty much everyday. [Especially in the car] my g2x has been suffering from "random reboots" running fauxs 1.2.8 and kernel 0.3.2. It was a new phenomenon, I thought it was the DS kernel I had rather than CM7, but all that did was affect battery life.
I finally was using my device when it decided to "turn off" and the screen just kept turning off ( less and less time being on, fractions of seconds.) Then it just stays off and the battery temp reads 100+° at turn offs.
It requires a battery pull to turn back on ( and I guess turn off) but the heat doesn't seem to come from the battery, but behind the camera, im thinking processor.
Could it be from the OC/UV kernel. I had on? It's on standard now.
Sent from my LG-P999 using XDA App

OC'ing can easily overheat/fry the processor (hence why there's always large warnings around it), especially if the kernel hits a race condition or similar.

The phones are passively cooled. and the radios in the phone heat up the phone when used heavily. I have not had anyphone that didnt get extrememly hot while it is using the radio when its in above 80 degrees ambient temperature and overclocking would just add to this. luckily most have a feature ot turn off the phone at a certain temp to protect the hardware. But I dont think this is a specific g2x problme my old droid does the same thing.

I took mine to a pool in Vegas. It was probably about 90 degrees. I had it under my lounge chair shaded listening to music. It had a heat stroke after about an hour.

I understand why/how overheating can be caused by oc but honestly if its not running at stock (or benchmarking) I have it set to 800mhz by default- its still fast as hell. It hasn't overheated in the last few days, but the problem was that even if I don't use it, it'll overheat.
I use juice defender to keep my radio off when the screens off, so I can't even lay blame to that.
I haven't really dove into undervolting, but in theory wouldn't lower voltage equate to less residual heating?
Sent from my LG-P999 using XDA App

mine does this running stock. Mostly when I have the charger plugged in and am still doing something. It will be taking a charge but the batery level will still slowly fall, once it gets below a certain point it gets really hot behind the camera and the screen starts locking and unlocking. faster and faster until you finally have to pull the battery and let it cool down a while.

YES!!!! I have 2 G2x that do this, and a guy at work has one. All stock phones, and can be doing NOTHING - gets hot near the camera lens, and LOCKS!!!! Have to pull the battery. I pull the battery for 1 second, re-install, and G2x works fine. I know of 3 G2x, and all do this. I can't believe I don't see more of this on this forum. T-Mobile has a "discussion number" on this: 265747. LG claims ignorance. I'd love to know how to "fix" this. I'd also like to know if GB fixes this.
The occasional re-boots are live-able - this lock up is NOT.

I can verify this is an issue with my phone as well! It was happening all the damn time in both stock Froyo and EaglesBlood Froyo, but as soon as I went to CyanogenMod 7 RC1, I haven't had it happen once.
And to those of you who haven't had this happen, it's like the Sleep of Death + your phone gets REALLY hot by the camera lens and it keeps draining the battery and putting out TONS of heat until you do a battery pull. It brought my battery from 100% to 25% in like 30 minutes of doing this.
But CM7 seemed to solve the issue. No more SOD+heat!

This problem has been driving me absolutely insane. My wife and I both got g2x's at the dame time (new from tmobile), and hers rarely does this, while mine does it continually. I was wondering if it was related to the case we have - but we both have the same case - the speck one sold at tmobile.

My wife and I both have the little rubber buggy baby bumper condom case thing that does cover the back - that would reduce heat dissipation. I often carry mine in a belt case that came with the phone from CostCo - she almost never uses that case.

Device getting way to hot!!!

I've gone to using my spare xperia x10 mini pro now cause I've found while i'm out an about with my sidekick it will randomly get really hot an I don't mean like kinda hot i mean like feels like someone poured a cup of hot coffee onto thigh! The device hasn't been abused or dropped an its always had a tendency of getting warm at random it seams on all firmware versions. The only thing I can think of is possibly a issue with the phone connecting an unconnected often with the Bluetooth in my kia soul.
Now before you ask why I'm bringing this up now I had a none android samsung memoir befor this phone an it would get warm while GPS was enabled. Though in the sidekicks case it does it no matter what things are enabled or disabled x.x
So anyone else notice thier sidekick getting warm? with mine it seams like its something in the actual phone getting hot that in turn heats the battery up cause its around the DEL key on the keyboard.

are you running a 1.2 ghz kernel?
are their any wifi connections/bluetooth connections or any data transfer in the background that could cause your phone to clock itself @1ghz or above?
do you have any apps that run in the background (beyond the stock rom) while you are not using your phone?
your cpu could just be getting hot from background app usage while running @ the max cpu clock speed or overclock speed if you're on a overclock kernel.

The phone has never been overclocked an its done it totaly box stock with no wifi,gps,bluetooth activated an no data being used an has done this aswell with any connections enabled or doing transfers over blue tooth though since day one i do get a FC buzz when it first starts up but doens't say whats FC'd also notice when its getting hot that the battery amount is getting discharged by 10/20%

Hopefully it never got overcharged, or undercharged...
Have you ever turned it on after it turned off from 0% batt (or done this multiple times), I know that Lithium Ion batts have issues (I think it is 15% on the battery, but as 0% to the phone) if they go below 15% (0% in the meter) they will loose the ability to work correctly from then on out...
Calibration ever done at "NOT 100%", so it might think that 100% is 90% (or more) and try to keep charging?
Do you not charge it every night? (I have always charged all LiIon batts every night [mostly] and I have yet to run into issues with ANY batt.)

best to charge the battery with the cover off takes heat away from it

the odd part is that the battery never is warm while charging stays at normal operating temp for a happy battery. Now what I'm thinking is the battery is actually getting warm from something in the phone itself an transfering the heat towards the battery. An this phone has gotten warm like this even when it was less then a month old on box stock none rooted firmware of all types x.x

50 degrees, ! how to cool my infuse down?

50 degrees Celsius!
I keep getting 45+ when I surf on 3G for a while while my environment temp is 30 degrees. I think my finger might even have slight burn from the high temperature today.
A guess is battery, I hit the temperature with batteries from Amazon.com
I haven't compare it to my original one yet. I had two, but the other one is cooler tonight. I'm not taking that into account since 1)the environment is cooler 2)I'm using wifi
So it have to be something to deal with either battery or 3G/4G.
Does anyone have the similar problem?
I'm on Scott's Cm10 on August 30. I really love this rom and I hope this isn't the source of the problem.
Thanks
edit: 3g does create massive heat on upper part of the phone!

are you overclocked?
You will always run hotter than the environment, so it it's a hot day that will make a difference.
My infuse usually doesn't get hot unless it's a sunny day and I'm driving using navigation. The infuse actually runs quite cool compared to some other phones I have tried. My wife has an Atrix that gets hot to the touch after a few minutes of light use.
I've only ever used the original battery in my infuse so i can't speak to that.

I did overclocked and am overclocking now. However, I tried to use and normal 1.2 and uc 800 before, I even flashed original /system to get the stock kernel. It didn't help to reduce the temperature, so I'm back on 1.4 now.
And my infuse got hot for several minutes of light usage, too. Both UCKL2 and UCLB3 have the same performance. not hot at all if I'm on a wifi

I find mine gets warm just under the camera flash, if I use it for extended amounts of time. But never to any degree that has concerned me. Is it the actual battery that is getting warm?

Sounds like a battery problem, try a cheap or friends battery.
If the battery is the problem replace it ASAP or you can damage your phone.

I subscribe a new number for higher data plan (in my country). However, I did a comparison showing with the old sim card it simply gets "warm", but with my new one my phone burns (whenever trying to connect to 3G). I'm at the same location, within an hour. The heat came from SIM tray and left side of the camera. Is it possible that I got a SIM with (partially) short circuit?

Anything’s possible. Personally fwiw (just a guess) from the info quoted, I’d be inclined to think there is something that is making your phone work harder to connect to the network, maybe a weaker signal (especially if you moved to more rural area) or some change in settings that occured when sims changed.
