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.

    Watching movies, playing real games, creating documents and editing photos are better on this than a phone, plus if it is WiFi only, the phone will act as a hotspot so I don't have to shell out for 2 data plans

    Article also mentioned 5000 doesn't improve much because of 15w CPU. Best it will reduce battery consumption when not running at 100%

    Except that some of us don't want anything to do with a laptop. I find the Surface Pro superior to my old Macbook Air for portability (smaller, lighter), usability on the go (where I'm only consuming content) and better when setup (better screen, superior for using with a real keyboard, etc).

    Ultrabooks are great from working in between point A and B. But the tablet is better for consumption in that time and also better for productivity at both point A and B.

    As a bonus you get a great screen and a really good drawing tablet.

    I am thinking of buying the Surface 2. No one mentions the obvious with RT machines which is that unlike Android, and Windows 8 they are pretty secure from bugs and bad software. It is attractive. I'm typing on a MBA 11 at the moment. I agree that the Surface is a compromise device, not quite as good as a laptop as an MBA and not as good a tablet as an iPad but it does both.

    I disagree with your comment. I have to attend meetings where computers are not allowed; however, you can take notes on anything that doesn't require a keyboard. Using the stylus on the SP2 is perfect for this and hooking it up to a monitor allows you to be very productive at home or in the office. My clientele can sign docs on the SP2 as well. P.S. The ipad sucks for taking notes because you have to use those worthless bamboo stylus

    nailed it.

    The Surface Pro is a good device, it's not bad to use regularly, but it's just not as good as a laptop in many respects. Folks at work hook them up to full monitors and keyboards though--they were given Pro's to replace their laptops. They often mention small text and keyboard as their main complaint.

    On a different note, most companies don't use tablets because they see them as media consumption/entertainment devices. Besides Surface, there haven't been any other realistically productivity-oriented tablets. Add in the high price which is either the same or more as a decent laptop and they will go for laptops every time.

    Tablets are getting used more in industry, but they have very specific niches. I hear that on some factory floors in Boeing, the techs are being given iPads so they can pull up drawings and installation/finish instructions in tight places. From what I hear, the approval rating is very high, and the techs are able to use their tablets in wingboxes and other tight spaces and immediately get back to work instead of having to crawl out of the space, look for the same information on their workstation laptops (which they have to leave in designated workstation areas because of foreign object debris concerns), print out drawings, and then crawl back into the working space.

    Obviously these tablets aren't replacing multi-screen quad core workstations for the engineers to do CAD, FEM and CFD on, but for the technicians, they seem to be working a treat.

    I would suggest anyone who think the Surface pro is expensive look up the Wacom Cintiq 13, for $999 I can get a nice stylus where I can draw directly to my computer screen,except I still need a computer to hook it to, for $899 I can a full stylus setup wit h the computer built in as the Surface Pro 2.. I'm sure the pressure and results are better in the Wacom Cintiq.. but as someone who uses a drawing tablet constantly, the Surface Pro appeals to me madly.

    You do know that the MBA gets 15 hours battery life in real world tests?
