Apple Inc. is investigating battery issues arising from updating an iPhone to the v3.1 operation system, following a lot of messages about the issue being posted on the Apple support forums. Users are reporting that after the update, the battery drains very quickly after being charged, and that performing a restore on the device using iTunes as suggested by Apple, failed to fix the problem.
Some users are being contacted by AppleCare helpdesk reps with a list of 11 follow-up questions focused on the battery. Additionally, an unsigned battery life logger is being offered for download that will collect information about the phone's battery life while it is in use.
Using various App Store applications, Push or Exchange e-mail, Wi-Fi, Bluetooth and other features can drain an iPhone battery a lot faster than regular use. However, the users complaining of the issue (mostly iPhone 3GS users) can't seem to get the problem solved by disabling features, system restores or other common suggestions from Apple support.
