PC World: "Another week, and yet another iPhone issue. Only this time, it's not overheating. Some users are reporting that the battery life on their brand new iPhone 3GS is not as long as they expected. And this time, it doesn't look like it's a hardware problem.
When Apple launched the iPhone 3GS last month, the company claimed better battery life next to the speed improvements the new device was bringing. But an increasing number of users are reporting on Apple's support forums and across the Internet that the iPhone 3GS's battery is not living up to their expectations."
