Apple has released a new software / system update for their 13.3″ Apple MacBook Air (all models).
It addresses two issues:
– Video playback
– Processor core idling
Apple strongly recommends that any third-party software that users have installed that changes anything having to do with the CPU such as speed / frequency or voltage should be removed before this update.
It sounds like part of this update could help increase battery life (i.e. the change having to do with the core idling).
