After upgrading to OS 3.1 earlier this month, I can't say that I've experienced any abnormal battery life issues.  For me, the battery typically lasts far less than a day, but it's no better or worse than OS 3.0.  While some seem to be in the same boat as me, a growing number of users are reporting issues, according to the Apple Support board.  Several individuals are claiming that battery life drops as much as 10-12 percent each hour, despite the phone remaining in standby mode.

Apple seems to be taking the issue seriously, dispatching the AppleCare helpdesk to affected users.  Those experiencing problems are asked a series of 11 follow-up questions regarding usage patterns and the number of battery draining features (Wi-Fi, GPS, 3G, Bluetooth, etc.) activated at the time.  The note comes with an attachment, which when opened, installs an unsigned profile enabling Battery Life Logging.  Apple recommends syncing more than usual, as the logs can increase in size quite rapidly.

Along with the "coma" issues that some are facing (encompassing random lockups and shutdowns), the battery life problem is a major issue worth reviewing.  According to a poll by The iPhone Blog, 24 percent of users are experiencing battery life problems under OS 3.1, so it's nice to see that Apple is addressing the issue.  Anyone else experiencing problems?
