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 think the Razer tablet might be a bit more focused than Microsoft is with Surface Pro. It seems like internally they bet on the Surface RT line for some reason and are shocked that the Pro line is the one that most want.

    I think they're leaving money on the table not making a Surface with Bay Trail.

    is it only me or, why I feel all these review are Microsoft paid review. The device is out there for quite some time and only today that all those reviewer sites suddenly decide to post a review on the same day. ps: It's Apple new product announcement day.

    and don't get me wrong, Amand's review has always been very very informative. but I dislike the idea of occupationize reviewing. I mean how hard can it be to find USD300 to buy and review it yourself? if you can't, ask shops to sponsor a unit and by return give them a free advertise. if all fails, auction it and a slight increase price, cause you have more fan base to support it. and also the advertisement income from website. it is tedious but that's what make the review more neutral.

    paid reviewer will always biased. And please shut m$oft door cause they've been good previously but now they want to shove and force you to eat win8. all these time they're backward compatible. Vista time, you can install xp, in 7, you can install xp, Vista. now? no option. you must die.

    I'm in the transition to buy many machine to replace. win8 is a pain to use. and all those ultrabook are ultra easy to break. useless stuff. precision are great device with great warranty but It's too high a cost for the time being.

    You got the idea of how tech blogs work wrong. For big launches like this, there is usually a review embargo for all websites. You also have to consider that Microsoft might have shipped out the devices for reviewing all at the same time

    you sound like you are being paid by Apple.

    MBA is an ultrabook. are you saying it breaks easily?

    ok, sorry about the last rage. I can always go to clevo or other OEM to custom made everything. but price will be very high. maybe I'll wait for next or else explore other option. ubuntu, droid, all support custom made software. not a big deal.

    now back to the article. This thing won't replace notebook in the near future. too fragile. no real keyboard, battery suck, it'll fail within a year. it's only good for our sales booth where only simple input are required. Heck, on our testing periods, they prefer the iPad more. the only best thing about this is the remote desktop or server thingy.

    the m$oft idea of putting office to clouds are stupid move. why would I share my info when I got my own server. and local storage is still the fastest access. cellular data are not stable. I understand that in the next future, all your device will only be a client but I really dislike that idea. client concept in an office is acceptable thou, investment wide It's still better. but when you are out there, you'll need to pay service provider for band with. this suck.

    Nothing, absolutely nothing is more expensive than MBA spec vs spec

    You know the Surface is sexy. I've thought about it and that is it really. It is unique. It isn't as good as a notebook as a notebook like an MBA and not as good a tablet as an iPad but it does both and really there has to be some compromise. It does both well and it is unique (OK I said that twice but there are a million laptops around).

    I don't think you understand how cloud-Office works. You don't have to store your data in the cloud. You can store all your data locally if you wish. You have the option of saving your data to the cloud, or syncing it via the cloud, but nobody is forcing you to do that. If you want to store your data locally, then you can do so, no problem at all.

    if the software is optimised you don't need all this horse power in this device. Guess what they own the SW, it isn't optimised hence the reason why they stick to higher end parts to make it smooth = higher cost and bad power consumption. In stead they would better focus on SW optimisation, that would help xxxxxxx users.

    "sharing a lot of the same DNA" ? I didn't realise a tablet was a animal.
