Apple has been contacting some iPhone owners that have been complaining about poor battery life after upgrading to iPhone OS 3.1 The company has apparently been asking select iPhone owners a series of questions about battery performance and asking them to install a battery life logging tool, according to The iPhone Blog.
The iPhone owners Apple has been contacting have all been involved in battery-related discussions in the Apple online forums. The forum members all received an email from AppleCare asking a series of questions about which applications they have installed, email usage, Wi-Fi and Bluetooth activity, and more.
The email also included that enables battery activity logging and transmits the collected data to Apple during iPhone syncing.
Apple will presumably use the information it is gathering to improve iPhone battery life, and make a long list of iPhone OS 3.1 users happy in the process.
