hi guys i find that when i use the phone for a little bit like on voice call or playing a game the phone become literally super hot and its reached 45 degrees c according to my battery indicator app is that dangerous and is anyone else had the same problem ?
my sgs2 also overheats! i don't know why
Whatever electric device You switch on and make it work it gets warm. If You make it work HARD it gets warmer to hot.
If You work it in summer and direct sunshine it gets hotter than under the same workload at the Northpole at Xmas.
CPUs produce heat under workload the same do screens. The higher the frequencies the hotter they will get.
It is simple physics. So what ?

i understand that the cpu and other hardware can produce heat however i would have thourght there would be some sort of heat regulator that would underclock it to reduce the temp like in setcpu when rooted. at what do u think is the highest temp the phone could go before killing it self ?

Normal cpus can go to 70 - 80 degrees C. I would say now if the phone doesn't go over like 55 degrees it's fine.
I don't think this is normal personally. My phone has become hot a few times now and I think it was wifi sharing process causing it both times.
I ended this process using the System Panel app and carried on using the phone in the same way and the phone cooled right down again.

I have frozen wifi sharing so I don't know. But my phone almost never gets hot except if I download big files.
the reason the phone gets hot is because the phone is very cramped and cant dissipate heat effectively . the simplest example is a laptop and a desktop, even though both may have the same configuration a laptop gets much hotter than a desktop because it cant dissipate heat effectively as a desktop which has much bigger heat sink

I am no my second GS2 and the issue persists.
Issue:
When charging overnight, the battery gets extremely hot. So much it warps the sim card. The first phone overheated until it died. Last night the second phone overheated until the warning message “charging paused due to temp” came up. I do use a CPU intensive app that uploads files to my server when plugged in. (so it doesn’t drain the battery). I have used all these apps on my old captivate with no issues with overheating.
I have tried Unnamed 2.2.1 and ICSreweD 1.6.1 roms, but the battery still overheats. Unless this might be a faulty batch from the store, what areas should I look into? At the end of the day, I would really like to continue to allow the app to run while charging. Especially since I have used it with less powerful phones prior. I have read others have this same issue with the GS2 but no solutions as of yet. Is there a different ATT phone that does not have this issue?
Silly question, but I know many who do this...
Do you place your phone under your pillow overnight while charging?
When charging and running a app that requires high cpu usage will overheat the battery. So close it at night while charging.
Damn warping the card. **** that's bad.
One time at football camp i put my shoulder pads in my ass
If you need to keep the app running while plugged in all night, what about using a plugged in profile in set CPU to throttle to 800 mhz Max or something...

Set it with setcpu or tasker. It's likely running at 1200 mhz all night right now. (assuming you don't OC). Try throttling it down to 500 or 800 mhz, it should help. Not sure if there's anything that limits specific apps though.

Try the lulzactive CPU Governor.
Sets max CPU clock to 200mHz while phones asleep.
Also great for battery life

If you absolutely have to leave your phone performing such intensive tasks all night, this is what I would try.
As twiggums said, it is probably running at 1200 all night and just melting itself. Unlike most computers, everything in our phones is passively cooled. Something else you might try is removing the battery cover (and any phone case) and placing a fan blowing directly on it. I know that is extreme, but so is what is happening to your phone.
Hope this helps.
I have also experienced this and it's really annoying. I couldn't love a human child as much as I love this phone but the overheating is not cool. I was using my phone to navigate while charging and once it got so hot that it locked up and another time it paused the charging due to thermal issues.

I had to do that sometimes when downloading some big files and tethering. Lol
Since my PC is caseless it wasn't that hard pointing a 120mm fan to it.
And yes it did work.

IIRC entropy mentioned some time ago that he throttles CPU to 800 mhz when using nav and charging...keeps it cooler and allows for slight charge rather than drain...
Sent from my SGH-I777 using XDA App
Yeah I'd suggest possibly throttling the CPU. I charge my phone while driving and stream Pandora and use navigation. I've got mine set to Max out at 500 while screen off and it works fine.
Ideally our phones should be able to handle sustained 1200 mhz. But then when you add a case and the heat generated while charging I guess it's too much for some. Guess it's the price we pay to have a beast of a CPU
Sent from my SGH-I777 using Tapatalk
thanks for the tips on throttling the cpu. i had thought about that and will probably do it but i still thinks its really lame that we have to do this. i dont even have a case on my phone. what are people who arent rooted and cant underclock their cpus supposed to do? oh well i guess
I have started to notice this on my phone. it happens when I'm in the car only though. Here's the situation.
It seems anytime I run Navigation my phone cranks up in heat to the point that I can't touch it. Is this a ROM/Kernel issue, or a problem in the phone itself?

Well if your sig is correct and you're running at 1600 MHZ, I'd say that's probably why. Running at that speed for prolonged periods is likely to generate some heat.

I run Set CPU and my sig isn't correct. Well, the 1600 mhz isn't at least. I have it capped at 1000. It's just odd that I can multi task any number of applications without a problem. I use navigation and instantly, the only application I can use is that one. Running Pandora or the phone or the phone interrupts pandora or the phone interrupts navigation and I get this error and the screen gets untouchable.

Hmm possibly reflash your ROM. I can run nav and Pandora fine, and my phone limits my CPU to 500mhz while screen is off. Or at least try reinstallin maps/nav, sounds like its gobbling up way too much CPU for some reason.

I told Pandora to not turn off the screen. I would think that Nav would do that natively or else it would negate the purpose of it. I wonder if maybe telling Pandora to keep the screen on and Nav keeping it on natively makes it think really hard and heat up.

My new TP seems to get rather hot. Is this an issue? It seems like the heat is worse when surfing and changing at the same time.
I would say that there may be an issue. Mine never got above 92 degrees. But its almost always at room temp ( around 70 degrees). Now my phone gets up to 104 if surfing the web on 3g so I guess it depends on the device.

Are you running any other radio type hardware when surfing or location based software when you're noticing the heat issue?
Buy surfing you're referring to just viewing web pages and not streaming video or gaming?

I am not using any additional hardware. I am just viewing websites.
I estimate that the temp is rather high. Not just warm, but hot. Most of the heat was located in the middle of the back cover.
Do you have an app or widget that display core temps?
mine is getting hot also while browsing the web, and battery is getting low pretty fast. this only happens while using android stock browser.
after switching to another browser the heating stops almost instantly....

mine get hot only when charging, I have mine clocked at 1.6Ghz on preformance mode, and it doesnt get hot when playing games.
it more noticeable when not useing the dock, I think it charges mush slower and thats the only reason is not getting as hot.
of you look at the design of the Prime the battery spans the lenght of the prime, so the heat will be middel but over the lenght of the tablet. if its the CPU from overclocking or over use, the hot spot will be top left middel.. ( if that make sence)
here is a pic of the board..

same here basically. plus nothing to be worried about. Prime has a fail safe in it THST if it gets too hot/overheat, it'll automatically throttle the CPU speed down so it can cool off and reduce the CPU temps. prime will never overheat out of control and burn itself up.

Interesting...I did not know that. Do you know around what temps this happens?
I've been using my i9300 S3 for a few days now and it seems to heat up on the lower back when using wifi/data extensively. It's not hot to cook an egg sort of thing, but it seems hotter than usual.
Any of you experience such issues?
Hello
I am first time android user. Even i noticed this. Please let me know if it's ok.
It feels normal to me though....but I guess extensive usage may increase heat, just like computers and other electronic devices
I noticed the heat issue a lot more when I just got the phone. It still warms up a bit but i would say it is normal.
Though it did get pretty hot on my last flight during take off that I had to turn it off. Didn't want my expensive phone to melt.

It's normal I wouldn't worry about it to much although it will get warmer if it is being charged while using the program.
I am facing a similar issue ! My question is what temperature is safe enough ? I mean I have used few battery info apps. I have got a temperature reading of around 42 - 43 degree Celsius ! Is it normal ?

S3 overheating
Krico is absolutely right. It happened this morning when I was charging thru a notebook using both devices at the same time. And the heat lingered on even though I unplugged it. So I switched it off and now it is back to normal. Tks.
The phone can get pretty hot using WIFI and 3g extensively or 3d games. This is normal, electrical components heat up after prolonged use, your computer heats up your tv heats up. As long as the phone isn't burning your hand or exceeding 60C you should be fine. My phone gets warm to the touch and noticeably heats up but doesn't get HOT, if your phone ever gets HOT, turn it off to avoid damage.
I use an app called temp cpu v2. It displays a few interesting stuff incl. battery temperature. There are probably other apps like this.
With wifi on I get around 26 degrees but it sometimes goes up to 50 (or a little more?) on 3d games using wifi.
While charging it gets a little hotter.
After how long does it get warm when you play games like NOVA 3 and such?
For me it does after like 10-20min which is somewhat short to me, but then again, I've never owned a proper flagship phone such as the s3 before.
My phone gets heated up to 47°c after 20mins of riptide.
What's the temperature your phone heats up to? I suggest you use badass battery monitor to check the temperature

Your phone does what?Are you overclocking or something?My S2 doesn't get to 47°C after 1h of NOVA 3 while still being overclocked(Both the CPU and GPU).And the S3 is supposed(And I think proven too) to produce less heat than the S2.
My S3 gets a bit warmer too. Think it will be fixed in subsequent rom releases. Same thing happened with my S2 when I had it; it went away eventually

My s3 barely produces any heat compared to my s2,that thing was burning the flesh in my hands... Maybe that's the reason nova 3 runs sluggish on my phone but not to anyone else?

Has stock roms ever fixed the heat issues through updates in the past (on other phones ofc), or do I have to root and flash a custom rom to decrease the heat?
My s3 also get very hot from both sides after playing 15 mins of shadowgun. I m using stock rom. And yea here temperature is 42C in pakistan lahore!!!

I can't find any details for the Exynos chip in the S3, but afaik most ARM devices have a Tmax (maximum CPU temperature) of 50-something (58?) degree Celsius.
So if it's already 42 outside, you can expect the system to be 52 as air-cooling is terribly inefficient, especially in hot dry air.
When you fire up some games it will thus go above it's threshold and automatically reduce it's performance to keep itself from being damaged due to overheating.
My phone gets really hot when using the data connection on the phone. When i surf the web, video chat, or do anything that uses the data connection the phone becomes hot. it also happens when i play games too. it gets hot around the lower part of the phone around the area where the home buttons located. Just wondering if this is happening to anyone else before i get it exchanged. The highest temp i got was 104 Degrees F.
i cant say for sure what temps are safe. i haven't done the research. but my wife and i both will notice the bottom getting pretty hot when pushing the phone. surfing & gaming. not so hot you cant touch it, but much warmer than any of my other droids iv used in the past.

Hopefully Samsung will make some firmware changes to better regulate clock speed according to temperature.

Yeah, just like in desktop computers, ambient temperature plays a big part.
Mine gets very hot as well. I'm on the 2nd one too. Its just because it is a very slim design, coupled with a strong processor = hot.

You can change the clock speeds with SetCPU, because they're set pretty high on stock, 1.5 Ghz max and 1 Ghz min.
Mine gets hotter with regular use to heavy use.
