The rollout of Apple's iPhone OS 3.1 update resulted in a flood of complaints, with reduced battery life being one of the main concerns. The iPhone Blog reports Apple is now investigating the poor battery life complaints:
An undisclosed number of users who have posted on Apple’s discussion boards about poor battery life following the iPhone 3.1 software update are being contacted by AppleCare helpdesk with a hefty list of 11 follow-up questions. These questions focus primarily on the usual battery culprits, email (especially push), WiFi and Bluetooth, and App Store apps. Number 10, asking “When you notice a power drop, does it seem to be a legitimate power drop, or rather an issue with the battery icon indicator?”, is certainly interesting.
The note also contains an attachment which, when double-clicked, installs what looks like an unsigned profile, similar to what is provided (in signed form) by developers using Ad Hoc provisioning for beta testing. (We’re guessing there’s a reason for it not to be signed, but — note to Apple — signing would make us feel so much warmer and fuzzier about it). This profile enables Battery Life Logging on the iPhone.
