No problems with mine...
No problems at all with my iPhone 3GS, nice and fast and no noticeable heat from it at all during use or charging.
Owners of Apple’s latest iPhone, the 3GS, have begun letting off steam online with claims that the smartphone gets hot enough to cause itself and its owners physical harm. iphone_3gs_burn This 3GS' owner claimed his super-hot phone caused burn marks on the back 3GS owners from around the globe have posted pictures and …

Nice lil hand warmer for those cold days out...
and was surprised it got hot. He probably complains about electrocution using his laptop under water.
"Just put the device back in the box and move away sir" There should be a minimum intelligence level for buying technology.
Let Apple do the software, Nokia do the hardware .Result...... a perfect phone.
Was playing with a friend's 3G S at the weekend, and even just browsing the net using Safari made the device noticably warm. The pink rubber case it was enclosed in probably wasn't helping.
However, I'm not exactly surprised that when kept between pillow and sheets and slept on, that it would get hot enough to burn. How is the heat supposed to dissipate?
Surely not as hot as the money that was previously burning a hole in the owner's pocket?
I can't say I've noticed my 3GS 16GB getting particularly hot, but I've not used it for more than an hour continuously.
It would be interested to know whether the users that have complained have been keeping their phone in any kind of case since that's not going to help heat dissipation (neither is smothering it with a pillow to be honest).
it does get warm with extended use, but not anywhere approaching hot. I suspect this idiot left his on top of a toaster oven. Much like my mate did with his apple newton (which turned into a blob of unrecognisable goo, but still worked!).
iPhone = iToaster
bring on those crumpets!
my iPod Touch 2G takes about 10 seconds to get quite hot as soon as you start a game.
Its always to the left of the dock connector too!
Also does it when charging... and the USB connector has started to get hot too now.
Maybe it's a new app called the Hand Warmer app. After all, there is an app for just about anything!
it does get hot, but no hotter than my 2G got.
I did notice, tho, that my 2G got hotter after it was upgraded to OS3.
That being said, neither were so hot to become uncomfortable.
[flames: for the obvious reason]
Mine gets a little warm but nothing to worry about and certainly nowhere near hot enough to burn skin
well what does he expect? That the heat will just beam itself to Arcturus? Or that the iphone suddenly works 100% energy efficient?
I'm N0t exp3ricing anY pr0blem-s witH m-y 3gggS at all all all all all
I'm slightly surprised no-one's taped a thermistor to the back yet...
Flames = hot, so therefore using that icon :)
This is clearly a result of this week's heatwave, and absolutely nothing to do with Apple's tech overheating.
Oooh, new icons. The choices! The choices!
you should try using my mac book pro for more than five minutes without the palm of your groin beginning to singe!
its a feature not a bug!
My girlfriend's always complaining about her laptop and power supplies getting dangerously hot. Whenever I check them they just seem warm. For some reason, for a certain size of device, some people seem to think that a bit of warmth implies it's going to burst into flames.
Presumably if he'd had it in his hip pocket he'd have been burned indecently ...
What about iPhone in pocket, how different is that?
Paris because of the obvious potential for 'hot in bed' japery.
the day they let hype determine their product choices...
my iphone 3g 32gb was replaced on monday last week with a battery fault, got very hot and drained flat very fast
first one back in the bristol shop apparently
Look, if it's a problem under a pillow, then it's a problem in the inside pocket of a cosy winter jacket. People WILL put these things in cozy places, and should consequently be designed with low heat dissipation (which also has the added bonus of longer battery life). If it was a laptop, then fine, don't wrap it in a duvet. This thing should be DESIGNED to be in a cozy pocket while performing its normal functions. However, let's take a closer look at it...
Now how much power does it kick out? Back of the envelope calculation: if it's using a 1219mAh battery at 3.7V (http://tinyurl.com/3gsteardown), that's a total of 4500mWh of energy available. So, he was playing music, which Apple claims it can do for 30 hours with a full battery (http://tinyurl.com/nowbfj). This gives a mean consumption (and therefore dissipation) of a piddling 150mW. Not enough to get very toasty at all.
Now, the iPhone 3GS weighs 135g (http://tinyurl.com/3gsspecs). So, if we assume that its specific heat capacity is comparable to that of steel (although that's possibly a weak link in my chain), i.e. 0.460J/g/K, we can calculate the maximum temperature rise from a full discharge, assuming NO heat is lost at all (e.g. in the case of being neatly insulated by a pillow). The heat capacity of the whole phone is approx 62 J/K. 4500mWh is equal to 16200 Joules (4.5J/s * 60 * 60), leading to a maximum temperature rise of 16200 / 62 = 261 Kelvin.
Even starting from room temperature, 281 degrees Celsius is pretty hot for anyone's money. Now it's probably unlikely to have absolutely zero heat loss under a pillow, especially over 30 hours of play, so it breaks down at this point. However, I conclude that it's theoretically possible for the iPhone 3GS to get hot enough to burn you severely. But probably only if it was made from highly polished steel and kept in a vacuum.
Those blaming the user for putting the phone under his pillow are totally missing the point. Of course being under a pillow isn't the greatest for keeping devices cool.
But why should you have to worry about heat dissipation when all you want to do is play some music? Do you think he would've had to worry about heat if he'd put a Walkman, portable CD player, or almost any other MP3 player under his pillow?
Does this heating begin during the use of the 'Onan' app? The one where you rub it back and forward to make it moan and groan?
Them: "I can't believe my beloved, holier-than-thou iFoney got so hot."
Me: "What do you expect, you pack it inside a cheap and nasty PVC cover and an entire bed and THEN lie on it whilst it's running an application, of course it's going to get hot."
Them: "Yeh but it's just a phone, y'know what I mean?"
Me: "If it's "just a phone" why the **** did you spend, and are still spending, so much money on it?"
Them: "Yeh but...because...well...but...but"
Me: *SLAP* "Twit"
I don't think any phone I have ever owned has gotten so much as warm? OK laptops get nicely toasty when being battered but never had it happen to a phone? Or am I just using it properly t really warm it up?
It's funny to notice,
The mere mention that something is wrong with the iPhone gets all of the fanbois who have parted their hard earned cash complaining on how idiotic the user is and how godlike the iPhone is. lol.
My Nokia N95 used to get extremely hot when several services were working simultaneously. It's not a big deal. Sounds to me as if some people out there are looking to manipulate a lawsuit (class action or otherwise) out of the slow release of a little thermal energy.
Firstly, i am an iphone owner, 3g.
No phone should get that hot from just being left under the pillow. Phone would be on standby so whats causing the heat. No mention in the article that he had left it playing music and even at that, there is no way it should get that hot. No matter what way you look at it.
its a flaw, simple.
That said, its probably not a flaw in Every iPhone, most likely confined to a limited number.
Also, has anybody noticed the volume of the speaker drop dramatically after upgrading to 3.0? Mine has gone down a good bit and yes, i have checked everything. Even uploaded a new plist file to increase it but didnt make much difference.
Holy cow! And for a Monday morning, you sir, deserve a holiday and beer! Feel free to take the rest of the day off :)
(P.S. I'm in Canada, only just lunch here)
If the screen and case didn't get hot, the components inside would get even hotter and fail.
As if they didn't test it ? Of course they did, Apple will know all about it.
There is a solution, reduce the clock speed. Simple for those who regard it as a real problem.
Could be profitable, for the first-mover any way.
Paris because she knows the copper's so well... or at least they know her.
When it gets too hot then it crashes even durring talkign on the phone.
What I learned from this is that I must have car windows rolled up and the phone must be clipped onto one of the air vents then within under a minute the iphone will be cool enough to reboot and will work normally.
someone's going to eBay their iPhone with a claim that the burn marks are a likeness of Jesus...
Well, lets put this in perspective.
Yesterday i set the 3GS in my dashboard dock, hooked it up to the charging cable and my stereo.
I set the music playing at max volume output, turned on maps, queued my location with the compas on, and drove 3 hours with the screen turned on. When i arrived, considdering the phone was not only under heavy loads, but also in direct sunlight on a black dashboard, and it's the black model 3GS, it was only comfortably warm when i arrived at my destination.
The trip back I did the same thing, but with the screen off. It seemed a bit cooler the second time, but not much.
I had a nearly 2 hour conversation with a friend last night, the phone in my pocket the whole time. No issues. Slightly warm, but it did not keep getting warmer after the first 10 minutes.
A 3 hour heavy load in direct, hot SC, sunlight (it was 102 degrees this weekend), and it was simply "noticably" warm. It did not feel hot, nor did i feel there was an issue. I turned off the screen, got the music running again though headphones, and thought nothing more of it.
Placing it under a pillow, or in an insulated winter coat pocket, that's a recipie for disaster. The device might make it a few hours without causing an issue, but extended use, say all night, and you're lucky it wouldn't explode. The heat has to go somewhere... My wife's camera phone gets hotter than the 3G S did when she leaves it playing music in her purse (it's not nice enough to auto stop when you unplug the headphones, and she often kills the battery that way).
I was using my iphone 3g every night to goto sleep with on the os 2.2.1 and all is well. and under my pillow.
First time I used it with OS 3.0 full charged and the charger was removed on the way to the bedroom and only on no more than 5 hours 30 mins as i went at 11:30pm and up at 5:30am I woke up and it was very very hot and the battery was total flat. and this was fully charged..at bedtime
Never had this problem at all with os 2.2.1
Also my iphone does not like my password, i have to sync it every time to get it to take my aol password which i have used with my iphone since getting it and has been my account details since i had the ipod touch 2nd gen, and all apple put in an email was the link for the forgotten password site. and this is on OS 3.0 again
Its sent to Apple's/O2 repair place and if its no better it will be cancel contract time...
Fire icon as that was how hot it was after 5 hours
Put a piece of compact electronic equipment under a pillow so all the heat is kept in, and then switch it on so that it starts to generate heat, and it gets hot.
Find me some electronic kit hat says 'safe to use when insulted under a pillow' and the whiner may have a point.
Why did Apple move away from the iPhone 1's nice metal back cover - cost? That is an excellent heat sink and it DOES NOT CRACK when you drop it - as happens with nice slippery shape stuff. Maybe its some marketing droids idea to sell some extra covers to keep the revenue stream going...
It just works... Until it melts.
"I had a nearly 2 hour conversation with a friend last night, the phone in my pocket the whole time. No issues."
...other than a slightly microwaved pair?
A number of Overheating issues are caused by the battery/electronics inside the IP3GS. With the Number of units being Mass produced this is to be expected.
Faulty lithium-based batteries pose a serious Fire risk in many products!
Cant wait for Fuel cells take off in the consumer market !
"No phone should get that hot from just being left under the pillow. Phone would be on standby so whats causing the heat. No mention in the article that he had left it playing music and even at that, there is no way it should get that hot."
Erm, from the article:
"Another iPhone 3GS owner told PC World that he fell asleep with the phone under his pillow while playing music through the headphones"
I read this article and I looked at the back. It looks normal under regular light, but under the sunlight, even for a few seconds, I started to see a major "color differentiation" from there. This could be the equivalent of the pink-red color. From experiences, the iPhone 3G S gets warmer faster while the original that I had used previously took at least 20 minutes to actually heat up, faster with Wi-Fi.
As others have mentioned, I can put any mp3 player or phone I've ever owned under a pillow and everything except my most recent phone wouldn't even be warm. My current phone does the 3G nonsense, which apparently means that it gets hotter and uses more battery while making the same phone calls. I've spent a lot of time out of 3G coverage, and it runs remarkably cooler and longer.
In any case, no pocketable device should become hot enough to burn you, or even make you uncomfortably warm, while it's being used reasonably.
Lol i don't know if you people do not notice but most people have a weird idea that they should keep their phones in their pockets! I mean idk what is wrong with these people but if your pants does not let the heat dissipate then what will be next. It's not Apple hardware that is the problem, it's people not willing to change!
"However, I conclude that it's theoretically possible for the iPhone 3GS to get hot enough to burn you severely. But probably only if it was made from highly polished steel and kept in a vacuum."
I love mathematicians.
"assuming elephants are perfect spheres with a diameter of 3 meters"
My iPhone was in airplane mode and was playing music on shuffle repeat all.
while under pillow.
So no gsm radio running as i have 3g turned off.
wif or bluetooth not on.
Yet very hot to touch and flat battery on OS 3.0
On OS 2.2.1 no problem with heat and even when one time i did leave phone turned on it was still playing music when i woke up and not hot.
Also I di dfind on OS 2.2.1 that sometimes If i got a call the screen would not come on and it was out in the open...
