How to prevent the iPhone 3GS from Overheating

iPhone_overheat

One of my friends has overheating issues with their free iPhone 3GS and asked me to have a quick search for possible solutions, which ranged from:

The sublime:

“If the iPhone 3GS is  in a closed or hard plastic case remove it and see if that does the trick. If so awesome.. if not call Apple it may be a defective phone and your friend can get it replaced.” ; to…

The ridiculous:

“Put it in iced water, since its water proof…”

I have visions of my friend trying to make a call with a bucket of water on their head!

Apple’s own support article gives some fairly obvious help!

Operate iPhone 3G and iPhone 3GS in a place where the temperature is between 0º and 35º C (32º to 95º F). Low- or high-temperature conditions might temporarily shorten battery life or cause the device to temporarily stop working properly.

Store iPhone 3G and iPhone 3GS in a place where the temperature is between -20º and 45º C (-4º to 113º F). Don’t leave the device in your car, because temperatures in parked cars can exceed this range.

If the interior temperature of the device exceeds normal operating temperatures, you may experience the following as it attempts to regulate its temperature:

* The device stops charging
* Display dims
* Weak cellular signal
* Temperature warning screen appears with the message “iPhone needs to cool down before you can use it” (see image below)

The error message appears when the operating temperature has become too hot. This is a safety mechanism that protects the components of your device. If this message appears, you should turn the device off, move it to a cooler environment, and allow it to cool before resuming use.

Note: When this message appears, the device may still be able to make emergency calls.

Some conditions and activities that may activate the Temperature warning message:

* Leaving the device in a car on a hot day.
* Leaving it in direct sunlight for extended amounts of time.
* Using certain applications in hot conditions or direct sunlight for long periods of time, such as GPS tracking in a car on a sunny day or listening to music while in direct sunlight.
