Battery Life
Surface Pro 2 retains the same 42Wh battery and 48W charger as the original Surface Pro. I wasn’t pleased at all with the battery life of the original design, and I had hoped for a significant increase in battery life with Surface Pro 2. Microsoft claims up to a 75% increase in battery life compared to the original. In our 2013 tablet battery life test that turned out to be a 40% advantage – not shabby, but not where it needs to be. Update: Microsoft issued a firmware update that brings Surface Pro 2 up to 8.33 hours of battery life in our web browsing battery life test, or 76% better than the original Surface Pro.
I’m also beginning to think that Haswell’s video decode engine may not be all that power efficient. We did see better results out of OS X, but it’s still nowhere near what’s possible on the best ARM platforms.

Blimey, can't you understand a simple metaphor?bull2760 - Tuesday, October 22, 2013 - link
Why are you running a battery comparison with the surface Pro 2 against ARM based tablets. Although the Surface Pro 2 is a tablet it by no means is meant to compete against them. It's designed to compete in the thin and light segment. This comparison is a waste of time. If your going to compare and apple to and apple than run battery tests against other x86 computers not ARM.Da W - Tuesday, October 22, 2013 - link
204 commentSeems like Microsoft finally got interest in its products.

"Since there's no connected standby 64-bit version of Windows 8/8.1 yet"I can't find this referenced or documented anywhere. In fact, several pieces of documentation like this one explicitly state the client versions of the OS *do* support it on x64: http://msdn.microsoft.com/en-us/library/windows/ha...
Are you sure it's not just a limitation from their choice of TPM 1.2 on the Surface 2 Pro?

The CPU on the first gen Surface Pro was pretty fast. They could have gotten away with something similarly fast from the 4th gen Intel chips, which could have allowed for lower power draw, which might have let them use a thinner case. Honestly, the thickness and heaviness of the Pro is what ultimately has me looking elsewhere. I'd be willing to pay near 2000 dollars for the 512 gig model if it was thinner. They are so very close to giving me something that can replace my tablet and desktop.mkozakewich - Tuesday, October 22, 2013 - link
It seems utterly impossible for people to compare this properly to anything else. I'd say the weird space in inhabits is its number-one strength, and anyone who's looking for a device right there will be wonderfully happy with it. Everyone else will look at it weird.Frankly, I can't think of a better device for me. (This is what any device choice boils down to: personal fit.)

Anand saying it needs to be thinner and lighter? Does everyone but me have girl hands, wrists, and arms? Does one not cradle their clipboards, books, etc in their forearms like people have done in the past?If anything, it feels like a good thin hardback book in my hands. any thinner and it feels weird.

Would appreciate it, but if it keeps the same size, a slight increase in battery would be nice. But the real estate seems full on the circuit board to me - considering this crams the equivalent of a laptop in one tablet chassis.ptman - Tuesday, October 22, 2013 - link
Reading Surface Pro 2 reviews from different sites I'm seeing quite the range of battery life reports - often reported without brightness figures and often compared with the iPad 4.Here I'm assuming the iPad4 9:48 figure coms from:
http://www.anandtech.com/show/6472/ipad-4-late-201...
and states "displays are calibrated to 200 nits"
Was the Surface Pro 2 calibrated to 200 nits for this battery test?
Reading this:
http://www.trustedreviews.com/microsoft-surface-pr...
The brightness was set at 40% (assuming a linear scale w/max 470 this would be ~188 nits) and the measured life was nearly 8 hours (although clearly running a different test).
I'm also confused by the inconsistency with
http://www.anandtech.com/show/7180/apple-macbook-a...
which also states the iPad 4 achieved 9.48 but states that the Surface Pro got 6.00, not 4.72.
I understand the discrepancy may be a distinction between the "Tablet Web Browsing Battery Life" test and the "Web Browsing Battery Life" test, but in this case the iPad 4 result would be 9.37, or am I missing something perhaps?

Just realized ananduser already brought this up - my bad
