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.

    I'm curious about this as well. The surface pro 2 is tempting. I kinda wish it was a quad core part as I'd like to use it as a desktop replacement, but my current system is a dtr laptop with a first gen i7 620m and from what I can tell this should be slightly slower, but perhaps not enough that I'd notice. I'm not really unhappy with the current cpu performance I'm getting so I might be ok with that. But it would be nice to say it's definitely faster. Do we know which sku's of i5 dell is looking at? Any chance there is an actual quad core part?

    Also can anybody confirm, with surface pro 2 using displayport, I should be able to chain 2 dell professional monitors together should I not? I have a U2413 with displayport in and out, I'm pretty certain I could run two of them from the single mini displayport on the surface pro2. That would definitely make the surface pro 2 a win over the dell in my books (which I believe uses hdmi)

    It has two fans in it and you wonder why the battery life isnt better? hahahahahah

    They really really really need to at least start putting a 4G HSPA+ Stack in this tablet. 4G LTE would be preferred, but just something that does not require me to carry a dongle or teather to my phone constantly. No doubt next year's version will have broadwell and a new chassis, and it will probably be the one to own, if they can get 4G integrated and connected standby.

    Anand, or anyone else - any chance MSoft will offer a patch in the coming months to improve SP2's battery usage? (that is, assuming it's a software issue)

    Very puzzling that there's a discrepancy in battery life - I would love to read some more from you about a more dedicated attempt to find out what the issue is.

    What's up with complaint about thickness? Yeah, it won't snap in half in your hand or suffer other kind of damage, but that is plus. Not to mention that thinness will cost you features and battery.

    A 2lb device can be cumbersome to hold for an extended period of time. People complained that the 3rd iPad was "heavy." If Microsoft can get the Broadwell Surface Pro down to the size and weight of an iPad they might sell considerably more of them. At 2lbs, it is more like a small ultrabook that you can occasionally use as a tablet, rather than a truly converged device.

    Argument was about thinness, not weight. That would count as goalpost moving... (Question however then becomes, do we have affordable materials and light battery tech for this use?)

    Also wonder how much weight adds display...

    what is the background u used for the photos? seriously that is more interesting to me than the surface 2 or the surface 2 pro. MS is capable of making good products but their marketing tends to suck, think ZuneHD. At their price point they should absolutely include the keyboard if they want to be competitive IMO. But seriously what's the artwork in the background!

    Hey guys. I'm really interested in purchasing the Surface Pro 2 as my laptop/Desktop/Tablet all-in-one wonder device. Thing is I'm quite worried by this statement "Since there's no connected standby 64-bit version of Windows 8/8.1 yet, Surface Pro 2 ships without the feature."
    Searching around google for windows connected standby, I came across this white paper from Microsoft http://msdn.microsoft.com/en-us/library/windows/ha...
    In it Microsoft specifically claims "All client versions of Windows support Connected Standby on capable hardware—both ARM and x86/x64 systems."
    In addition the article indicates that a lack of connected standby support would prevent many VOIP/IM services from functioning properly when the device sleeps as connected standby enables device wake-up in response Wake-on-Lan (WoL) Patterns.
    The alternative would mean that the surface pro always stays in a full powered state. Interestingly enough, if your comment turns out to true, I wonder what this would mean for the rumored LTE surface pro 2. Mobile data without connected standby wouldn't make much sense .

    not true. that was a iTurd who commented on that.
    my Surface Pro still had >60% batteries left after 2 weeks of inactivity. i didn't turn it off but i suppose it was in hibernation because i closed the lid(keyboard).
