    Default iPhone 5 getting warm during normal use

    I haven't seen a thread about this so far, feel free to point me there if i missed it.

    My iPhone 5 gets warm during use. My old 4 used to get warm during graphically intensive stuff like games, but not during normal use. I'll typically be in the car, having it plugged into the charger, bluetooth-ing music/podcasts to the car, and maybe using it to go through Twitter (while parked of course!).
    At this point, the phone is noticably warm.


    Is this normal? I'm not sure if it's just the aluminium body radiating heat more than glass, or whether my phone actually gets hotter than normal.

    Yep, it's been happening to my iPhone with the the 4S and 5. When you consider the processing power in the iPhone, it makes sense it will get warm, together with the metal casing that acts as a heatsink (of sorts). It's nothing to worry about though.

    What does bother me is when the iPhone is on my car dashboard on a sunny day (not even a hot day), it gets so warm, it shuts down whilst I'm using it as a navigation device

    That happened to me the other day - have me a fright to see my iPhone unworkable because it was too hot. At least there's no apparent permanent damage.

    Those with overheating phones whilst using GPS (or anything else for that matter) in the car would do well to get a holder which attaches to your airvent. When I first got my 3GS, I was doing the dashboard thing and it was always shutting down or just overheating. I got myself a dedicated air vent mount for that, but had to get a more generic one when I switched to the iPhone 4 temporarily. Now I have a 4S, that mount is back in service, and I would not even try to use the phone with GPS running, without the a/c playing over it to keep it cool.

    This is the one I have, but there are others. I do not use the windshield attachment, it bounces around like an old drunk.

    I don't have an iphone 5, but it ought to, because its the same width as a 4. If you have a case on your phone, all the better. I have also used it with the 3GS, an Acer Liquid Metal, a Huawei Sonic, and an HTC Desire. All about the same width with various thicknesses. There doesnt seem to be anything specific around for the 5, but it might be worth a search. Just be sure to get one that mounts to the air vent.

    As phones become thinner, your hands are closer and closer to the parts radiating heat and there's less chassis to absorb and dissipate it out. As a general rule, phones getting "warm" is normal. Phones getting "hot" (as in, uncomfortable to hold) is not.

    I have a windscreen mount that has an arm that I can pull down so I can direct my side aircon vent upwards to cool the phone - doing this means my phone is cool instead of warm now. I also leave space between the phone and the holder at the back for airflow.

    Have had that happen to me one time, but it was a scorcher of a day, in a car that had spent the morning out in said scorching day. Was a bit worrying, but after I let it cool, I made sure to blast the A/C on the phone to make sure it didn't reach worrying temperatures again!

    I guess it's good that it is smart enough to shut off, rather than have permanent damage caused.

    As phones become thinner, your hands are closer and closer to the parts radiating heat and there's less chassis to absorb and dissipate it out. As a general rule, phones getting "warm" is normal. Phones getting "hot" (as in, uncomfortable to hold) is not.
    Luckily the only time mine has been 'hot' is when it's mounted on the windscreen, in the sun, doing LTE, Bluetooth and GPS. Just warm in normal ue.
    Your point about thinner phones making your hands closer to the heat radiating parts makes sense too.

    Thanks everyone for letting mee know your experiences, comforting to know it's normal and not something I have to ask Apple about!
