Today, Microsoft released the 2.3 firmware for Zune. This release is a minor release that does not add new features but fixes a battery problem. Many users, including me, have experienced a draining battery even when the player is “turned off” by holding the Play button.

After upgrading, other than the fix for the battery issue, there is also a very apparent increase in performance. The player tends to freeze up much less often and the animations are a lot smoother.
