iPhone 3GS Tips to Prevent Overheating, from Apple

In light of a spate of recent iPhone 3GS overheating reports, Apple published a set of guidelines to help iPhone users ensure that their devices remain at proper operating temperatures to prevent overheating and related issues. More accurately, Apple released the tips the day that many of the initial reports surfaced, last Thursday, June 25, so it's unclear whether or not the two are connected--Apple has not issued an official comment on the reports. But the following information could be valuable to any iPhone owner concerned with possible overheating. "Burned" iPhone 3GS (via NowhereElse.FR) with iPhone Overheat Warning Screen.

From Apple:

•  
  • iPhone 3G and iPhone 3GS should be used in environments where temperatures remain between 32 degrees and 95 degrees Fahrenheit. Temperatures outside of this range could decrease battery life temporarily or effect performance.
  • iPhone 3G and iPhone 3GS should be stored in locations where temperatures remain between -4 degrees and 113 degrees Fahrenheit. Note: Temperatures within sealed motor vehicles can exceed 113 degrees Fahrenheit.

iPhone owners who don't follow these suggested best-practices could experience any of the following "symptoms:"

•  
  • iPhone could randomly cease charging
  • iPhone display could become less bright
  • iPhone cellular connection could weaken or diminish
  • iPhone temperature warning screen could appear, rendering your device useless except for making emergency phone calls

Apple also included the following suggestions, though most of these are simply common sense, at least for experienced gadget users:

•  
  • Don't leave your iPhone in a vehicle during a hot day
  • Don't leave your iPhone in direct sunlight for any extended period of time-Avoid using data intensive applications, like GPS or streaming-media apps, for extended periods of time on hot days or while in direct sunlight.

Note: Apple's iPhone overheating tips appear to be aimed specifically at iPhone 3G and iPhone 3GS owners, but I'd say they're equally applicable to first-gen iPhone users. I'm guessing there's no temperature warning screen on the original iPhone, though.)

I've got a few of my own tips, too.
