why does my iphone become hot to the touch?
iPhone 4 will occasionally become hot to the touch. This seems to happen randomly, without any rhyme or reason, or warning.
iPhone 4, iOS 6.1.4
Hello dhartz61,
When troubleshooting temperature, please refer to the following article:

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:
iTunes: Restoring iOS software
