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.

The Penny Arcade review of the original Surface Pro was one of its best reviews. The review was in the context of an artist but oh did it really serve that niche well. Based upon that review, I recommended to an artist to read and consider the Surface Pro. Didn't wind up getting one as the Haswell based one would be worth the wait in terms of battery life and/or performance.I will add one thing that would be ideal for the Surface (2) Pro: a tethered monitor mode so that it could emulate the functionality of a Wacom Cintiq display. (Basically the Surface Pro becomes an external touch screen for a different host computer.) That really would be a killer feature, albeit niche.

"I’m actually curious as to why Surface Pro 2’s Haswell implementation seems only good for around 6 – 7 hours on a single charge, while other devices we’ve seen manage to deliver substantially better. I have heard that Microsoft didn’t work all that closely with Intel on Surface Pro 2, which might explain some of this gap."The battery life is disappointing, especially considering the testing you did on the MacBook Air 2013 and i5 4250U (http://www.anandtech.com/show/7117/haswell-ult-inv... The Surface Pro 2 has a higher resolution display and active stylus, but I still thought 8 hours of browsing would at least be possible.

Anand's results do not jive with what other sites are reporting.I'm seeing 7-8 hours with regular usage is the norm.

Er, yes they do. They 'jive' perfectly. The Verge states even less battery life. Engadget only do a video playing test which they have to redo.Anandtech is the only one who perform reliable, consistent benchmarks which you should pay attention to.
What you personally see obviously depends on your own usage pattern. The whole point of benchmarks is that they remove that as a factor. They tell you how tablets compare with the same use.

And then you realize that not even that will tell much of story, until power options are written down. (If you can...)Kevin G - Monday, October 21, 2013 - link
Do the other reviews have the brightness calibrated at 200 nits? I see that as a differing factor between battery tests.teiglin - Monday, October 21, 2013 - link
The Vaio Pro 13 managed over 8 hours in the light desktop battery life test with a larger screen, the same silicon, and a smaller battery (37Whr vs. 42Whr) and it's my understanding that the tablet web browsing test is even easier than the desktop light test. What browser do the desktop tests use? Also, I know time was an issue, but desktop tests would be nice for Surface Pro 2, as I think the usage paradigm for this device is quite a bit more strenuous than iPad/Android tablet usage.ananduser - Monday, October 21, 2013 - link
I read that Chrome has a bug on Windows that prevents the CPU from going idle. I recall Anand's latest PC battery tests having idle times built it so that a faster unit does not get penalized for doing more work. Maybe Anand used Chrome; I know for a fact that Jarred used IE10/11 for the Vaio.kyuu - Monday, October 21, 2013 - link
That's interesting. If true and Anand used Chrome for the battery test, it would definitely skew the results. Hopefully Anand looks into that.kyuu - Monday, October 21, 2013 - link
Nevermind, further down Anand stated that he used IE11 for all the battery tests.
