    I haven't been away from the mains long enough to verify but iStat Menu consistently shows time remaining about an hour longer than in Mountain Lion. With light usage, integrated GPU only and display at around 3-4 notches I'd anticipate around 8 - 9 hours' endurance.

    I've read reviews where the Haswell 15" rMBP lasts anywhere from 11 - 12 hours under similar conditions, which sounds about right to me.
