Here's what I'm getting AFTER the update just with normal use: 3.5 hours. 

Exactly same as before the update.
(yes, for some reason the graphics card is on high, which appears to be from an external monitor being plugged in - but I'm just web browsing and messaging mostly so I can't see why it would be taking up so much energy just to send a video signal. The monitor has it's own power, obviously. )
EDIT: unplugging the external monitor drops power usage by 20W or more, which gives me much better times. Looks like the graphics card is a hungry beast.
