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.

    wow, you guys actually tear-down it before ifixit did.

    I've been trying forever to find any info on connected standby. According to a MS whitepaper (http://msdn.microsoft.com/en-us/library/windows/ha... page 7), Windows already supports this for ALL platforms:

    "All client versions of Windows support Connected Standby on capable hardware—both ARM and x86/x64 systems."

    So shouldn't that mean the Surface Pro 2 already supports this? Unless the hardware is not up to snuff, in which case no software/firmware update is ever going to address this. There's no clear documentation anywhere online, was hoping you guys could clear it up.

    And further to the point...with Connected Standby enabled, I'm wondering how much battery life I get when idle.

    Dear Anand,
    I generally like your reviews, however I fail to understand your slashing remarks regarding the battery life of the new Surface Pro.

    Regarding the battery life, you say, and I quote:
    "...seems only good for around 6 – 7 hours on a single charge..."
    "Battery life is still not up to snuff with traditional ARM based tablets"

    I just can't grasp how can an adequate reviewer compare a desktop designated CPU (designed for ULTRABOOKS) to a ARM devices (which are primarily designed for PHONES), and EVEN so: Surface manages to give 85% of battery life of Galaxy Tab 3, while providing 5-10 times faster CPU & GPU performance (really!).

    Answers, please...!

    I agree with your statement.

    This tablet has a full blown Intel haswell chip clocking inside. Whats the point in comparing it to weak, small ARM core's battery life?

    Ditto here. Even better with a 3rd (or even a 4th or a 5th) screen using a usb3 hub plus a video adapter.

    I'm not sure MS has gotten used to the speed with which tech devices like convertibles are improving. The Pro was groundbreaking last year. This year it has competition. Next year, the competition will be even stiffer. Broadwell has the potential to be a game changer for the OEM that puts it all together. My thought is that Dell could be the big winner. The XPS 12 was been a nifty idea in need of better hardware. It's already a pretty decent laptop, just not a compelling tablet. Make the XPS 12 thinner and lighter and it might be as good a compromise as anything out there. And that does not take into account what Sony or someone else will do with Broadwell. MS needs to look at Google and the reasons for its success in its devices so far: aggressive improvements coupled with aggressive pricing. The Surface Pro 2 shows that MS has not yet learned that lesson.

    I'm really curious to see how the Dell Venue 11 Pro will stack up against the Surface Pro 2 in terms of build quality and pricing when it comes out in a few weeks. I know it's a busy time of the year for everybody but I really hope somebody at Anandtech gets a chance to review it.

    I'm holding my breath for more configurability - I'm okay with a 128GB SSD, but I wouldn't want to settle with less than 8GB ram. I also think they may have made the right choice with their choice of the Y sku i5's. Hopefully they can offer up some strong competition - I'm really interested to see what they come up with.

    Amazon currently has 3 of the Venue Pro 11 SKUs listed: http://www.amazon.com/s/ref=nb_sb_noss?url=search-...

    It looks to start at $550 for the model with an Atom. Moves up to $650 for the Pentium, then $850 for the model with a Core i5. There's supposed to be a Core i3 option as well, which I'd guess will fall in at the $750 mark, given the way the pricing is structured. Atom model comes with 2GB of RAM, all the others with 4GB.

    So you're not going to get better specs, and the Core i5 model is only $50 cheaper. I'd pay $50 more for the better chassis and accessories, myself. It is interesting if you're looking for a cheaper tab that doesn't use Atom (with the Pentium and Core i3 options).

    Kudos for finding pricing information, I had been looking earlier and had not found it. I agree with your sentiment about paying a little extra for the premium build quality that MS has been delivering. It also appears that Dell is charging extra for the stylus, effectively bringing the two devices close to the same price point if that functionality is important to you.

    I still find myself hoping that some competing company can actually deliver the product I'm really looking for. Microsoft is so infuriatingly close with the Pro 2, but I can't help but feel they did not iterate the device enough this round, and it needs one more revision. For the premium price point it's difficult to make the investment in something which doesn't feel quite ready.

    As an aside, a big part of why I'm interested in the Venue 11 Pro is the Transformer style keyboard and power dock, although this is definitely a matter of personal preference.
