Apple claims the iPhone 3GS has a slightly increased battery life in certain areas. However, owners interviewed in this LA Times article are finding a much different reality, paying a premium for phones that can't even last through a workday without being plugged in. Even the company suggests on its website that users disable some of the phone's most vaunted features, including the faster 3G network itself, to keep it from shutting down during the day. Industry officials and outside experts sketched a complex picture of the technical and bureaucratic limits that might explain why, after two years and three generations of the device, the newest iPhone has less stamina than the first.
