What does the iPhone and vampires have in common? Both apparently can be killed by sunlight. Apple says that the following warning can occur when its phone gets exposed to sunlight.  (Source: Apple)
Apple finally responds to reports about its heat issues

Apple has been having plenty of headaches lately with its MacBook Pro displays failing and experiencing distortion.  Worse yet is the iPhone 3G S's quality problems, which include reported overheating and signal issues.  

The overheating was first noted in Apple support forums.  Soon, though, writers at several tech publications -- PC WorldWired, Le Journal Du Geek and The Telegraph -- began to notice the problems on their own phones.  The Le Journal Du Geek writer posted pictures of a white phone and noticed that the overheating was so severe that it colorized the plastic.  The heat tended to turn the case pink or brown.

Now, Apple has at last issued a response and it is assigning the blame for the problem on its users' behavior, sunlight, and on the seasons.  Apple says that leaving the device in a car on a hot day is one possible culprit causing its phone to overheat.  Apparently, like a vampire the phone is no friend of the sun --  Apple states that "leaving it in direct sunlight for extended amounts of time" may cause it to overheat.

Apple lists the use of "GPS tracking in a car on a sunny day or listening to music while in direct sunlight" as two particularly dangerous operations.

According to Apple the following problems are the result of the iPhone's overheating:

  • 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)

Apple says that the iPhone is only meant to operate at temperatures between 0º and 35º C (32º to 95º F) and be stored at temperatures between -20º and 45º C (-4º to 113º F).  Unfortunately, this is much lower than the temperatures experienced in much of the American South and Southwest.

Based on Apple's stance it seems there's no immediate solution for iPhone owners.  Apple seems unwilling to agree that its hardware needs revision to deal with the problem, instead assigning the blame elsewhere -- the sun, heat, and summer weather.  And that means as summer temperatures heat up, users are left to prepare for the worst -- their phones beginning to fail.

I can attest to the American Southeast exceeding the recommended operating spec range. I wonder though if iEmployees are informing their customers of this "limitation" at purchase, especially in my area. Somehow I doubt they are.

It is impossible during the summer months, especially July and August, to maintain within safe operating spec througout the whole season. 95 degrees is the low end of the high for an average day here. It easily gets to be between 97 - 99 degrees on a daily basis, and our heat index is routinely 100 - 105 degrees.

That is a pretty lousy design for a mobile device having such a low ceiling for heat tolerance.

Thankfully I don't have to care - as I won't buy an iPhone to begin with. Thanks Apple for giving me more justification for my purchase avoidance!

Heh, the high today for Phoenix is 108, with a much higher heat index. We're over 95 for 8 months out of the year, so I guess Phoenix residents can't use their iPhones.

Austin, Texas has had a heat-index of about 100-110 pretty much the whole of the last half of June. My 3G definitely gets warm but it is in an AC environment much of the day. If I do go out to the lake or live music or something, I don't use it much but I have never seen a heat-related error message before.

I wouldn't be a very happy camper if I did see one, considering summer temperatures average above 95F.

In that heat, I would be too tired to call anyone anyway.

But it's a dry heat.
