Users report iPhone 3GS 'faults'Overheating, battery life and SMS vulnerability

06 July 2009


Apple iPhone 3GS users have been reporting that their iPhones have been overheating, leading in some cases to discolouration of the rear panel of white iPhones. 

Apple has published a guide on its website titled 'Keeping iPhone 3G and iPhone 3GS within acceptable operating temperatures' which lists certain conditions and activities that may 'activate the temperature warning message'. These include 

  • 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.

iPhone 3GS battery life

Some iPhone owners are reported to be disappointed by the battery life on the iPhone 3GS handset, and Consumer Reports magazine in the US reports that the iPhone 3GS battery lasts one hour less when making calls than the original iPhone. Which? will update its iPhone 3GS essential guide with the results of our own iPhone 3GS lab tests on 23 July.

The Apple website has more information on the iPhone 3GS battery with recommendations on how to prolong battery life. Tips include turning off power-hungry features such as Wi-Fi, Bluetooth, 3G, sound equalizer settings, and push mail and notifications, but many of these functions are integral to the flexibility of the iPhone as a web-connected device.

iPhone SMS security flaw

Security experts say that they have discovered a flaw in the way the iPhone 3GS handles SMS text messages, prompting Apple to create a software patch to fix the issue. 

The bug, discovered by security expert Charlie Miller, and disclosed at the SyScan conference in Singapore, could let attackers 'run software code on the phone that is sent by SMS over a mobile operator's network in order to monitor the location of the phone using GPS, turn on the phone's microphone to eavesdrop on conversations, or make the phone join a distributed denial of service attack or a botnet.'
