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.

    Reading this it seems like Microsoft played it safe, or maybe it's just the lack of execution we've become used to seeing with the WP8 platform(although the updates on that area is picking up). Hopefully the much-lauded "re-org" can change things to become much better for the third generation.

    The Surface Pro is still too expensive considering that the batterylife isn't up to par.
    Reading the review, it still feels more like a jumbled 2-in-1 laptop rather than a tablet with a keyboard cover.

    The whole point of the Google Nexus series is to show the other OEMs what is possible to do. It's priced quite cheap - in relative terms - and you get good hardware for the money. If we compare the Surface series, can anyone say it is driving the ecosystem to the right place?

    Is that a joke? The surface pro is widely regarded as very good for it's price compared to other ultrabooks in the same tier, as well as versus the MBA. Good perf, good display, and while the battery isn't great, it's not horrible either for the form factor and the power it pumps out. Reply

    The Air has longer battery life, a proper (better) keyboard, Intel HD5000, a much better trackpad and is cheaper. The Surface Pro has a stylus support, a touchscreen a better screen.

    The thing is that as a laptop replacement it's not good at all, simply the experience of typing is too inferior and so is only having to angles for that hinge.

    To be honest with you, with regular ultrabook hitting 8-10 hours battery life in very small 11.6" sizes, the Surface Pro and tablets in general (unless you don't want to spend as much money as you need to to get an Ultrabook) are pretty much useless, especially if you own a smartphone.

    MBA starts at $999

    Surface 2 starts at $899 + 129 for the keyboard. = $1028.

    So I guess we should add in the cost of a Wacom pad to the MBA, huh? Reply
