Just got the iphone 5 today, my iphone 4s never used to get this warm. Its not so hot you cant touch it but just very warm whilst loading all my apps back onto it/connected to the pc.

Is it normal?

yes, if it's connected to the PC and loading apps on to it then it's bound to get very hot.

Once it's all done let it cool down for a bit and then use it. It should stay at its normal cool self. If not then there is something wrong with it and i suggest swapping it for a new one.

Ok thanks.

So playing games or watching HD videos YouTube etc should not make it even slightly warm?

Playing intensive games should make it slightly warm/hot. HD Youtube videos will be warm if screen brightness is all the way up.

The main thing that is contributing to the heat problem described in the OP is the fact that the charger is plugged in.

You should be able to tell the difference between warm and piping hot. If the phone is getting piping hot, even when not being used much, then there is something wrong. Getting warm is normal though.

Mine gets very warm if I use it heavily on 3G. Very warm indeed. I know of others who have encountered the same thing. Not so warm that it's unusable, but warm enough that I can really feel the heat of it if I put it in a trouser pocket.

It will not let itself get so hot that it gets damaged if that's what your worried about. I left my 3GS on the windowsill years ago in direct sunlight and when I went to pick it up it had a caution triangle on the screen saying it had overheated and to let it cool. Once it cooled sufficiently it turned itself back on. The best way to check is that if it's sitting idle and isn't heating up then it is probably fine.

If you're worried at all take it to an Apple store and ask them to check it out (this will be free).

Yeah its only warm not hot, just asking as my iphone 4S never seemed to get warm so im not used to it.

And i didnt know that if they get so hot they have a caution sign pop up? thats pretty smart, luckily in my 4 years of iphone ownership ive never seen that, and hope i never will lol

Thanks folks

I have been using my iPhone 5 constantly for the last number of hours with only a 35 min break and have a cover on it and it's still not even warm so you could well be right about something.

Leave it in sunlight and you'll see what I mean or google it. I'm sure there'll be an image online.

Think it's ok yeah, was only when loading apps on and playing a game. I'm using it to type this and it's fine.

By the way gotta say I'm loving the extra screen size and speed boost over the 4S, games are much smoother too, screen colour/sharpness is superior too.

Happy days!

i used my old 4s as a dashcam in a screen mount. With GPS running, charger connected and in direct sunlight it got so hot it threw a warning and shut down to protect itself... so it will manage its temperature.

But in your case the heat sounds perfectly normal, i just mentioned the above so you can see it needs to go much further and even then it will protect itself.

I've just watched a couple of episodes of breaking bad, tethered over USB to my laptop. The phone gets warm at 100%, if it is charging as well, it gets pretty hot.

The only time it seems to get hot is, using it whilst charging, expecially play games and off the charger, extended GPS and 3G use, especially simultaneously.

My 4S definitely gets rather warm with even moderate gaming or watching of videos. Classic case of form over function, there is definitely nowhere near enough cooling on the device.

It'll be fantastic on a winters day; hands cold? Pull out the iPhone and watch a video

It's designed this way on purpose. Its casing being aluminium, the whole thing is effectively one big heatsink.

It's similar to laptops. Unlike a typical plastic laptop whose case is not heat conductive, a metal cased laptop can feel much warmer on the lap when working hard. But the benefit is they can make them much thinner as they don't need to accommodate large separate heatsinks.

Interesting, never thought about that.

The benefit can also involve them getting slightly uncomfortable to touch; the drive for faster faster faster isn't always win win ....

Thats normal.

When I use mine for tethering it gets warm.

I wouldnt worry, they shut off if they get too hot.
