In an article here:
http://www.computerworld.com/s/article/9238843/Intel_39_s_Haswell_gets_massive_graphics_performance_boost
Computerworld quote Intel as saying, and I quote from the site:

"The chip maker has said the battery life of ultrabooks will double with the
new fourth-generation Core chips."

What utter rubbish! Considering that, in current 'Ultrabooks' the display is
the single sub-system responsible for the greatest power draw, and the CPU
draws on average 35% it's physically impossible for a simple CPU upgrade to
double the battery life.

If it's twice as efficient, as they seem to claim, then the CPU will only
draw half as much - meaning a reduction in power draw by 17.5% - about a 20%
increase in battery life. That's a far cry from a 100% increase, Intel must
think that we're all morons. :-/

The article was not about a simple CPU upgrade.

Yeah, it is. Ivy Bridge to Haswell. Both have GPUs built in.

Indeed, and not 'between the lines'. They're saying the Haswell will allow
'4K' playback on a laptop but don't mention no laptops in existance have 4K
displays or how much power it would take to run one.

They say: "A 28-watt Core i7-4558U doubles the graphics performance of the
17-watt Ivy Bridge chip." Duh! It uses nearly twice the power! *And* it's
next-gen - it'd be a disaster if it *didn't* double the graphics
performance!

(Since both major /CPU/ manufacturers have been heading in the direction of
/APUs/ for a couple of years now.)
