My newly bought iphone 5 is heating while im calling and using internet

Hello asif.ker,

When troubleshooting temperature, please refer to the following article:

iPhone, iPad, and iPod touch (4th generation): Keeping device within acceptable operating temperatures

When using the device or charging the battery, it is normal for it to get warm. The exterior of the device functions as a cooling surface that transfers heat from inside the device to the cooler air outside.

By all means, if you believe the temperature is a concern, you can isolate the issue by restoring your iPhone as new:

That is normal, especially if you are using 3G

I use my iPhone for lots of mapping/GPS and yes it does get very warm.

Just verify your operating temperature and you should be set!

Hi Matt,

The above information is useful. Thanks.

But I checked all the details and all are intact for my iphone 5s which I bought just a month back.

Still when I talk for long time (10-15 mins) or use internet from more than 10 mins, the backside of the phone getting heated up.

Is this normal for any iphone including 5S?

Kindly provide more details around this, as a new buyer it is worrying me.

Thanks.
