[Q:] How hot is too hot?

I was just running 4G and wireless tethering. When I checked my phone it was at 40c/104f. If I left it running I don't know if it would have gotten hotter.
How hot is too hot for the Evo?
HTC Evo
Rooted, but still stock...for now
----------------------------------------
The program is designed to work, if it's not, we have a problem.

I wouldn't go over 50c

Using 4g and tethering wirelessly is probably the most intensive thing you can do on the phone, so that temperature is pretty much normal for that activity.

How cold is too cold?

I've hit 120F on mine doing 4G tethering while playing a game. It's still here and I've had it since a week after the release date in June.

Hrm, sounds like an opportunity to experiment with peltier cooling for the Evo
But good to know the phone can take some heat...will still watch it to make sure it doesn't get too hot.

It will probably turn off and reboot when it gets too hot, happen to me before, I didn't see what the tempature was tho

I've noticed that while thetering with 4g if the temp gets above like 95f the connection speed tanks so I put it in the window sill I found that it works best at around 75f I have no idea if these things are relayed in any way tho actually

I had my phone when I was out hunting one cold morning and had it out of my pocket, I looked at the battery info and the battery was about 1C. I immediately put it in my pocket to warm back up.

Ive hotten my phone to 143 before having it on the charger and tethering 4g. I had just downloaded a 4gb file from start to finish. Some apparent internal saftey came on stopping the charger current, and causing my notification led to flash orange and green intermittantly. It scared me. But phone still completely functional I now watch my temps more closely

I've had my phone up to about 135F in my car dock running navigation, Pandora, and a dash cam app recording vga quality video.
It stopped charging and started flashing red or yellow (the sun was bright, another heat issue, so I couldn't really tell).
The screen was super hot to the touch so I dismounted it and pulled the cover to hold it in front of my ac vent for awhile.
I closed the apps and brought it down to 110F before charging again.
No issues.
Pretty sure the phone protects itself like most computers, so don't worry too much about it.

I hit 200 C while compiling a custom gentoo distrobution on my evo while overclocking.
No but really i have SetCpu underclock if it hits 42C

The highest mine has gone has been 42.7C and that's charging/wifi tether/4g and I was also doing dev work, so it was plugged into my comp and screen always on.
No lights, nothing, just my Evo being a beast

[Q] CPU overheat and crash, help?

My wife's Epic 4G was working fine yesterday but today it crashed and overheated pretty severely. When it was still plugged in and crashing it showed the battery charging and then it turned yellow and show a yellow warning triangle with a thermometer beside it, is the phone going to stop working on us?
I would appreciate a quick response so I can take it to Sprint and see what they can do about it.
I just factory reset it to insure that it wasn't a rogue application or what not and the phone is still running slow, not as bad as when it was crashing, but it still works so I don't know what's going on with it.
Also the phone is stock and has always been stock without root or any other type of hacking, etc.
It just stooped working perfectly one minute.
She showed me that the screen was blinking rapidly in an up and down bar fashion on the home screen and during applications.

First of all how old is the phone. My phone runs games hot all the time and never crashes (well sometimes, but usually when im not even doing anything with it).
I would think that the video is going out on it and it is rebooting. Depending on the age I think your phone is dead dude.

Not a year yet, it'll be a year old in June or July. I'm hoping it was just a virus or something because its working now. Should I exchange it anyway?
Nabbu eats your face.

Try flashing it back to stock or wipe the data if it isn't already rooted. I've never heard of anything of this sort... need some screenshots or something.

I already factory reset it and it's running right now as if it were just fine but what I'm wondering is if it's going to happen again and not work afterwards.
I'm thinking about taking it in to Sprint and exchanging it but I'm afraid there might be fees for exchanging or what not. The phone has been dropped multiple times but it never had any issues before.
The drop distance has been less then 2 feet every time.
No water damage to the phone itself but the Sprint tech said the battery's "water damage" indicator was activated and showing water damage.
The phone HAS been in the bathroom during multiple showers which might be the cause for the battery's damage indicator to go off but the phone, like I said, has never had any issues.
She downloads pretty much everything from the Market so I was suspecting viruses or malware and now it's "clean" it's running fine.
Any suggestions for where I should go from here?

The phone should be fine. This has happened to me a few times.... if your phone gets extremely hot it will refuse to charge as a safety feature and show that yellow triangle thing... open the back of the phone take the battery out and let it cool down.

That's the best advice i've gotten on here! Thanks a ton! ^^b

Happened to me my battery got near 118*F so I took it out and let it cool on some aluminum and put it back in was fine
BTW you can't take a screenie because phone shuts it self off
Sent from my SPH-D700 using xda premium

I'm guessing that the overheating problem had to do with a buggy app that was running on the phone and took lots of data or cpu time. This has also been know to happen when running wifi hotspot apps.
Regardless, like everyone else said the phone went into thermal protection mode. The battery got hot and it wouldn't charge the battery until it cooled down.

Could be the screen being on and maybe running a governor such as "performance"? Also, I've left my phone under a pillow charging, woke up it was 110F and I haven't had this problem it mustve been really hot

THIS! ^^^ Without looking at your phone, I'm guessing this was the culprit. She had a buggy/defunct app that was probably frozen in the background while still sucking CPU/RAM. I've had a few of those instances and it DEFINITELY increases the temperature of the phone.
Only other thing I can think of is if she runs her phone at the brightest setting and has a long timeout on the screen timeout. Either way, I think it's nothing a little spring cleaning of the apps and tweaking couldn't take care of. Good luck buddy

Normal for S3 to get warm on bottom of screen and back of phone?

This is my 2nd S3. First ones home button stuck down and wouldn't come back up. That phone never got warm at all. I was wondering if this is a normal occurance on the S3. My phone now gets rather warm while surfing the net and checking email for about 10 minutes at a time. brightness is at auto (as was the first one) and all settings are as the first one was. Just wondering if I should do a warranty swap since I am now over my 30 day return mark.
Thank you all
AJ

Mine does the same thing. Most phones will get somewhat warm with heavy use, the S3 seems a little more susceptible to it, maybe because of how it's designed.

Mine will get warm as well. I haven't had it get hot except for when I use it for GPS in my car which is understandable considering I turn brightness all the way up with gps/data/wifi and have it charging at the same time.

Yep perdectly said thats the only time mine has gotten overly hot!

mine gets warm, never hot. I do notice that on this one it is, as I said, towards the bottom. The first one I had never got warm at all. I'm hoping I won't have to go return this one warranty wise. I love the phone. LOL. When I called ATT to ask them the question they said No it's not normal and to return it, then asked if I have heard about the Iphone 5 coming out LOL.

The chipset is in the bottom area underneath the simcard/sdcard slots.its normal for it to warm up.However if its superhot then no......usually massive heat will damage sone sdcards happens all the time at my store.

I have one day left actually on my 30 day returns policy. Should I utilitze this and get a new one? If so does the white or blue make a difference? I hate returning phones!!!
(Update)
This darn thing just got so hot it shut itself off and all I was doing was texting LOL!
AJ

Mine gets warm when charging or both GPS/DATA are on.
Once, I got a "system is too hot" warning when I left it charging under a pillow.
I think it depends on how much you use it...some days, when I play games or watch Netflix for 20 minutes straight, it gets a little warm.

If it legitimately shut itself off while you were just texting because of how hot it got. Return it now.
That isn't normal at all.

Hot Galaxy S III

Purchased my GS3 last week, and noticed it got very hot with use but wrote it off as my phone working overtime downloading all my apps and setting up my accounts. After that I noticed it still gets hot browsing the web using chrome and looking at pics on Instagram, up to 45c! Upgraded to JB through Kies and the problem persists. Temps I'm getting are 28c-45c, are these normal temps for this phone? Im getting 41c typing this and listening to music through PowerAmp. Wondering if I should return to BB for a replacement. I'm also running stock everything. Tried searching for answers but got mixed results, some yes some no some say just root and flash a ROM.
Any help and suggestions are appreciated.

i get around 30C/90F on my phone. but 35C/95F with intense use.

So this sounds about normal temp. But does the back of your device get hot also?

i only notice it getting hot when im playing a game for a good amount of time

Under no to light use, I've seen the phone get as low as 23C (which is about the same temperature as the ambient environment; wow). Moderate to heavy use puts it at 30-31C, and if I'm overclocking the thing and, say, playing videos on it, it can get as hot as 38-39C (I have to really work at it to reach that temperature, though, and it's definitely not very stable at that point).
I'd be concerned if you're clearing 40C, particularly if you're not overclocking the phone or anything.

I Been browsing the forum for quite a while now and my phone is Luke warm at best, but probably more so from my hands then anything. I'd say you got something running hot, get it replaced.

Thanks for the responses guys, I think I am going to return it for another one from BB. LOL i'm averaging 40c right now and I didn't do anything but respnd to a text from my wife! I'll do a factory reset, if nothing improves by this weekend I'll return it.

104 degrees Fahrenheit, thanks Samsung

so my phone is charging I get a phone call yep hot as he'll burning up...

You realize 104 F is not hot... at all.....
1) Laptops and have had electronic components built to withstand up to 100 CELSIUS for years. I'm sure your phone can handle 40.
2) If you can't talk on the phone because a little warmth is too much for your sensitive skin move the **** to Alaska because 104 is not hot by any stretch of the imagination.
3) My phone has no lag.... at all, so I don't know what you're speaking of. I can play NFS:MW for an hour, switch to Eufloria HD for another, then hit up GTA:VC for an hour with absolutely no problems. I can also scroll through the drawer faster than my S3 could respond, so it is much more responsive. Maybe you got a defective unit or you messed it up somewhere rooting or flashing roms or poking around where you shouldn't have... I mean based just by your grammar you're not that smart of a person, so I'd say user error is MUCH more likely.
4) If by the blur you mean the purple when you're in the settings, well yes. You've got me there. That is a minor bug that needs to be addressed, and will. The phone has been out for like 11 days bro, give them a ****ing minute.
5) No, sir, your Note 2 is not faster. Yes, it has a larger screen and slightly better battery life, but faster? No. Run a CPU and GPU benchmark and try to tell me its faster.
Give them some time to work out the kinks in the programming. This is how electronics work, nothing is ever going to be perfect when its being produced by the millions on a short time frame with 6 different versions for different countries with different hardware and 10000 different carriers trying to poke around and make their own adjustments to the software.
TL;DR: Stop crying, you're embarrassing yourself.

hi you

I hate when people say use benchmark look which is faster... man everyday use is what matter, when I'm playing games and my note 2 runs them smooth and my S4 runs them choppy there is an issue I'm sorry there just is. Now for 104 degrees being not too hot, wow really its beyond hot for a phone to hit, don't give me the whole laptop crap this is a phone that people use to make phone calls and the screen and the back just feels way way too hot. Just use the speakerphone what are we Apple "You're holding it wrong" come on guys give me a break a 670$ phone should not have all of this stuff going on. Then you're telling me oh download an app to fix the screen issues -.- , you guys may think this is over the top i don't think so when you buy something so expensive and it works so iffy, don't get me started on Shealth love it but keep restarting your steps all the time ... might as well call it Srestart ..... oh samsung i love you but you're killing me with this phone. I'm getting a replacement on monday I'll let you guys know how that one is hope its 100X better....

No, 104F is not too hot for a phone to hit while charging and being used. You have heat from the battery while charging and heat from the processor while using, add any case you might have put on there trapping the heat and it is still well withing acceptable parameters. In Florida ambient temperature reaches that through most of the summer.
And if this thread continues to be a flame/troll fest it will be closed.

Like everyone else had said, I dont think thats very hot. Thats around where mine is

104° F is actually cool for a phone th that's charging and in a call. If the device is lagging out on you just return it if a reset doesn't fix the issue.

I actually had this same issue on a white 16gb s4. Phone was powered off while charging over night. Upon powering it on the internal thermometer also read 104F. I suspect it was much hotter, given I have hot spots on my laptop case that reach that temp as verified by a thermal camera. This felt much hotter, though I didn't have the tools on hand to verify.

I've heard a few people complain about their devices getting too hot, but most of them have had the white version. Is that what you guys have had? I have the black one and haven't experienced this issue at all. It does get a little warm when charging, but other than that, no issues here

Im shocked that no one has asked this. But...

Well I'm in Florida so whenever I'm inside it's like a warming pad against the AC. When I'm outside I don't care because it's not getting any hotter than the air already is. Sound logic.
You do realize I was being sarcastic right? Regardless, that's neither here nor there. You can't make a thread and be like "Damn samsung my phone hits 104 F when I'm charging and talking on the phone!!!!111oneone"
That's not hot. Especially for a phone that's charging while doing anything, or using mobile data in any way, or playing games. When it hit's 60-70 celsius start complaining about overheating problems/return it. When your phone hits 100 degrees Celsius start worrying about the internals frying. Anything less than that stop complaining. It's a ****ing quad core computer that fits in your hand and is slimmer than a BIC lighter. Of course it's going to get warm. If you didn't realize that when you bought it you shouldn't be paying 650 bucks for anything because you're too stupid to have 650 bucks to spend.
For the last time, that's not hot at all. This thread is pointless. I'm done with it.
