Apple investigating iPhone 3.1 battery life issues

Following a multitude of complaints from iPhone owners reporting severe battery drain after upgrading to iPhone OS 3.1, Apple has begun to contact select users asking for their help in tracking down and diagnosing the problem. These users are being contacted by AppleCare with a list of 11 questions focusing on the user’s current configuration, including push services, Bluetooth and Wi-Fi use, and installed applications. The email also contains a small attachment which installs a profile on the iPhone that enables battery life logging, enabling Apple to collect data about their devices’ battery usage the next time they sync to iTunes, in hopes of isolating, and fixing, the issue.
