According to AllThingsD's John Paczkowski, Apple has just released the following statement regarding iPhone battery life in the just-released iOS 5.0.1 update:

The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices. We continue to investigate a few remaining issues.

What makes the statement interesting is that iOS 5.0.1 was ostensibly developed (and pushed out so quickly) primarily to solve battery complaints that had been coming from iOS 5 users on the iPhone 4 and 4S, so Cupertino still has a little bit of work to do. Is there an iOS 5.0.2 in our near future?
