If there is no physical damage done to the device here are a few steps to try and resolve the issue.Advertisement Check the Temperature Feel the device and determine whether the device is unusually warm or cold. If the device feels hot on the back where the battery is located or colder than usual let the temperature return to normal. There is usually a message that will appear if the iPhone is too hot to turn on but not if it is too cold.

This will give the battery a chance to get a charge if it was overheated or if it had been exhausted.Advertisement Go to Apple for Help If all else fails take the phone back to Apple. If there is no physical damage you can sometimes get a replacement for $150. If you have a warranty through Square Trade, Apple Care+ or with your wireless carrier, start there.
