Microsoft Surface Pro Review
by Anand Lal Shimpi on February 5, 2013 9:00 PM ESTBattery Life: The Downside
Despite having an integrated 42 Wh battery (similar in size to the 3rd and 4th gen iPads with Retina Display), battery life is a real sore spot for Surface Pro. Haswell is really designed to drive platform power down to very low levels, which should help close the gap between ARM/Atom based tablets and Core based tablets. Unfortunately, Haswell for tablets won’t hit until the third quarter of this year, which forced Microsoft to use Ivy Bridge.
In our tablet benchmarks, I never saw Surface Pro break the 6 hour mark on a single charge. In most cases I’d expect to see 5 - 6 hours out of Surface Pro in light, tablet usage. Video playback was especially disappointing as Surface Pro managed to use more power here than during our web browsing battery life test. I suspect this might have to do with the relative power efficiency of Ivy Bridge's video decoder. It'll be interesting to see how Haswell does in this department.
I also put Surface Pro through some of our new notebook battery life tests for 2013, and here it didn’t fare too bad. I only have Acer’s 13-inch S7 to compare to but Microsoft managed 3.85 hours in our medium workload compared to sub-3 hours for the larger Ultrabook:
| Windows 8 Notebook Battery Tests | ||
| Battery Test | Acer Aspire S7 (13-inch) | Microsoft Surface Pro |
| AnandTech 2013 Light | 4.00 hours | 5.2 hours |
| AnandTech 2013 Medium | 2.88 hours | 3.85 hours |
This is easily the biggest disappointment with Surface Pro. You just won’t get the all day battery life you do with an ARM based tablet out of this design. I expect Microsoft will have a solution to this problem with Haswell, but not until the end of the year.
Charging
Surface Pro retains the same large, magnetic power connector as Surface RT. In fact, Surface RT’s power adapter will still charge Surface Pro. The Pro model does however come with its own 48W adapter. It’s a nice looking, but large and still fairly traditional two piece power supply (brick + detachable wall cable). There’s no sophisticated cable management other than a tiny hook to help keep the device end of the cable together. One neat feature is the power adapter does feature an integrated USB port for charging your smartphone.
Under max charging load the power supply will draw around 27W at the wall. Microsoft included a 48W unit in order to be able to charge and power the device without slowing down charge time. It took me 2.692 hours to charge Surface Pro from completely empty to 100% with no additional power draw at the wall. The quick charge time is pretty nice and about the only reprieve here when talking about Surface Pro's battery.
I did notice something odd with the first power supply Microsoft sent me. When charging through my power meter, I picked up some interference in the capacitive touch screen itself resulting in around 10% of my taps not being recognized. Microsoft supplied another power supply that seemed to resolve the issue.

How about they put all the bulk in the keyboard section, attach it permanently, and get rid of the kickstand? That way you could use it anywhere, even on your lap! Sounds much better.Seriously though, this is a painfully awkward gimmick, and I'd much rather have an ultraportable laptop.

I'm a prof photograph and film maker. I use my PCs with adobe production suite and other sotfwares. I have a light version on my laptop too when on a shooting but I thought that the Surface Pro, with a smaller footprint would be the perfect tool as an enhanced monitor and controler (different applications) for my cameras. My wife received an ipad 4 for Christmas and since then I tried to find a usefull application beyond what a 15 year old would do with the thing unfortunately I'm still on the quest of findings something productive (work related) beside converting my ipad into a slate (which I don't need) or a remote control for my tv or my pc.The surface pro looks like a good, (I do not intent to edit or do any post prod on it) idea but if I understand correctly the product has the same disease as the ipad stuff; no video input! I understand Apple's business model to brickwall the user whitin the "I"universe but MS? Why can't I use the Surface as a monitor? After all it offers more than decent quality? Why should it be limited to an AV output??? If my understanding of the product is right, that's a big no no for me, I'm still stuck with a laptop.
The battery drama is real only when you compare the product with non-computer product like Android and the i stuff, I do not have any problem with that as I have a ton of very good batteries that will power the Surface for a long time except that I would need a 12vdc charger (lighter plug) that is not offer on MS shop.
Why is it that when buyng a $1200 I have less technical details then buying a $10 toater? Tried to get an idea about power consumption; over the battery stuff, there is no info, idle power amps, low work load, heavy. I know it depends but would be easy to set a minimum and maximum. The point being that this piece of hardware should be used in more remote location and situation for people than needs the power and freedom of use, this is not for the kids chatting on facebook, this is for working people that needs to do the other stuff.

it has a usb3.0 port, how do you not consider that an option for av input?Soda-88 - Monday, February 11, 2013 - link
Does anyone know what type of SSD is in the Surface Pro? Is it replaceable with bigger mSATA drive for example?Soda-88 - Monday, February 11, 2013 - link
Nevermind, just saw this:Update: It looks like the C400 SSD is an mSATA drive, likely similar to the one we reviewed here a while back.

I feel anandtech is spot on with their view of microsofts product: essentially an ultra book with tablet capabilities. If you were to take such a view you'll find the surface pro rather pleasing. It's funny the way some argue against it. They say the androids and ioses can do the same things and are worth more. A 128gb iPad @ 900usd needs an additional Bluetooth keyboard, can't take USB and is stuck at how much it's given. What's the difference? Yes it gets 9hrs of life. But it can't do photoshop; it can't do GIS applicationS it can't do serious video editing. This device and many others like it (Lenovo, Samsung etc) strides the boundary between tablets and ultra book.This and upcoming generations will make mobile computing true. The androids and iPads are stuck by their oses limitations and will never be able to do what this device does (and they are not meant to).
I will seriously consider this over the MacBook Air if I didn't have one already. The life is similar but the surface pro is smaller and comes with a pen to boot.

The Samsung ATIV Pro 700 has been out since December of last year packing the same CPU, 4GB of ram and 128GB SSD. Claiming that the Surface Pro is easily the fastest tablet on the market just sounds as if you were paid to write this review....

So far I've actually enjoyed using this device except for the fact that there are no WinTab drivers for the Wacom digitizer. That means no pressure sensitivity in many graphics applications like Photoshop and Corel Painter, which is a huge bummer for me. Lisa Gade is the only reviewer that I've seen that discusses this.For now, I'm waiting and seeing if WinTab drivers will be provided in the near future. Otherwise, I'm making do with ArtRage for the time being, given that it supports Microsoft's newer pen API and thus does register pressure-sensitive input. Touch controls (pan, zoom, rotate) are an added plus.

I agree with you. I too enjoyed light gaming, CADing, and used ArtRage. Corel Painter 12 doesn't support pressure, but finger pinch zoom and two finger rotate works. I do not understand the people saying the better option is making do with price equivalent of a ARM tablet and a laptop.For as I used my Kindle Fire, I wished I can view things as smoothly as my PC and work with it better in terms of input, both hardware and software. I like my Envy 14 1st generation laptop, but I have and still do an awkward disconnect with using my Intros with it. Even placing the digitizer on tip of the Envy's keyboard still is awkward for lap use as I have to remove it for keyboard use.
Hence I am glad and have gotten a Surface Pro. I was considering the Samsung ATIV 700T, but if its keyboard dock was heavier with a second battery and maybe second removable mSATA SSD, I would have picked that instead.
I hope some group, either one, solves the pen capability in Painter (and PhotoShop and others too).

My 128GB has a samsung mzmpc128hbfu-000mv. AS SSD clocks in at 471.31MB/sec read, 252.33MB/sec write on the sequential test. 89.4GB free out of the box, 110GB total capacity (as measured by c: properties).
