Apple has warned iPhone users to keep a close eye on their devices during the current heat wave to avoid encountering overheating related problems.

Charging issues, dim displays and weakened signals, are all unwelcome by-products of iPhones being used or stored outside of optimum temperatures, according to a support notice on the company’s website.

The heat issue affects both the iPhone 3G and the latest generation, the iPhone 3GS.

“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,” Apple’s support page states.

Similarly, Apple advises users that their phones should be stored at temperatures of between -20º and 45º C (-4º to 113º F) and to avoid leaving their devices in cars because their temperatures are often outside of this scale.

In certain cases, the iPhone will display a temperature warning screen that will flag to users that their phones need to cool down before use. They may still be able to make emergency calls, however.
