Amid unconfirmed reports that some 3GS iPhone are over heating and turning models with white cases a light brown, Apple has released a document that advises owners on how to use their devices to avoid potential damage caused by a silicon barbeque.
Apple says you should operate your iPhone 3G and iPhone 3GS in a place where the temperatures are between 32º to 95º F (0º and 35º C ). Low- or high-temps might temporarily shorten battery life or cause the device to temporarily stop working properly.
Store your iPhone where the temperatures are likely to stay between 4º to 113º F (-20º and 45º C). Leaving your iPhone in your car on a sunny day is not a good idea because inside temps in a parked car can exceed this range.
Some clues that the interior temp of you iPhone is beyond normal range are:
- 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"
The warning message is a safety mechanism that protects the components of your iPhone, Apple says. If the message pops up on your display, turn the device off and let it cool down before firing it up again.
No worries: Even if you get the warning message, you’ll still be able to make emergency calls, Apple adds.
You’ll see the temp warning message under the following conditions, Apple says:
- 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
For what it’s worth, I’ve been running my new iPhone 3GS nonstop since I received it 4-5 days ago and have not experienced any issues with over heating. In fact, the only issues I’ve experienced with the new phone is an over abundance of goodness.
