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.

    um no because unlike this product, the MBA can function without a touchscreen. Obviously missed the point. Reply

    For that extra $29 you get a device that can remove the keyboard and be a tablet, which you cannot do with an MBA, to do that you also need an iPad that is hundreds of $$$ more and the inconvenience of carrying 2 devices. The MBA is a great laptop, the iPad is a great tablet; and never the twain shall meet. Reply

    The MBA is a great laptop and the iPad is a great tablet but the Surface Pro is neither a great laptop or a great tablet. Its far too heavy for a tablet (it weighs 2.5lbs with the type cover), and it doesn't work as a laptop since you can't really use it in your lap (the keyboard flexes and kickstand is unstable). The screen is too small for desktop apps also.

    The Surface 2 is even worse, it still weighs 2lbs with the cover (almost twice the weight of an iPad Air) and has almost no apps available. Both Surface tablets don't really work in portrait mode.

    For the record I have an iPad Air and a Surface Pro.

    dunno why this keeps getting compared to a mac book air. this is a tablet, has a 1080p screen, and runs windows in all it's glory. Reply

    I know this sounds dumb and kinda defeats the purpose of a tablet form factor....but just save your money on the keyboard and use one your own and plug it into the USB 3.0. Especially since most of those tablet/type cover keyboards suck for people with normal to large size hands. LOL Reply

    Air is not HD, does not have a touch screen (SP2 has capacitive touch screen, which is more expensive than a regular touch screen) and does not come with a digitized stylus. Is in the same ultrabook frame that requires very little Research and Development. Don't be naive Apple is all about profit margins. The Air could be sold at $700 easy, but Apple wants to squeeze your pockets. They say hybrids don't work bc they don't want them too, not because they don't. Apple wants you to buy a $1,000 MacBook Air and a $500-$800 ipad without any accessories. Reply

    I guess those numbers also doesn't show the inclusion of a 10 point finger touch screen either in the comparison. Reply

    You get the MBA for about $999 with a keyboard and 128G Storage so yes, it is cheaper when you cost it out. Reply

    The $899 has 64GB of storage and the keyboard is an essential part, and the keyboard is an essential part Microsoft should bundle, the Pro 2 without the type cover is just a terrible tablet and even worse "laptop". Reply

    Air is NOT cheaper when it doesn't have a Wacom Pen or a touch screen, or even an Microsd Expansion slot. When you add all those in, Air cost > $2000.

    you (and many others) gotta stop confusing a "type cover" vs a "touch cover". Type cover is as good if not better than ANY regular laptop keyboard.

    When you have a touchscreen, a good touchpad is negligible.

    and STOP STOP confusing your smartphone os with a REAL full featured Windows OS. they serve different functions.
