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.

I think you are missing the point...This is a Windows x86 product we are talking about here, something that we know will eat it's own disk space in temporary files and other junk.
Android and iOS are a 'lot' more frugal when it comes to data usage.

I don't know what to expect... But it seems collectively, the surface has more bad reviews than good. In fact, anand wasn't even gung-ho about the device for the first half of the review. In fact, there are just the mentions of the limitation of what the surface is.So let's get one thing out of the way: battery life. average life I've read around the net is 3.5-4 hrs for regular usage -- which is probably worst than the yoga pad. Now i'm just thinking... doesn't the mbp have longer battery life then this? isn't the technology out there yet?
The surface would've been a different story if it had better battery, and came out with data plan enabled -- your favorite LTE carrier. This will make people turn heads more. I was excited to get one this weekend, but I've been put off by all the negative press...

What did you expect from Ivy Bridge based design where battery has to be squeezed in the 10" tablet? I am actually quite surprised the battery results come in as high as being reported. 6 hours of browsing - that is very acceptable. 5 hours of video streaming is better then most ultrabooks on the market.nathanddrews - Wednesday, February 6, 2013 - link
This is a topic that I wish would get more attention. I've noticed screen tearing on nearly every Windows 7 and Windows 8 laptop when outputting to an external display, whether cloning or closing the lid. It doesn't seem to matter whether it's Intel, AMD, or NVIDIA graphics hardware or whether HDMI or VGA is used. Doesn't matter if hardware acceleration is enabled in the browser, the game, or video player, the tearing still occurs. The presence and application of Vsync doesn't seem to affect it either.The only consistent symptom is that it is sometimes worse than other times. I suspect that Windows desktop composition is to blame in some way, but I can't prove it.

I was waiting for the surface pro, but decided to get the Vaio Duo 11 instead because of a few extra connection options, such as ethernet, HDMI, and I appreciate the backlit slider keyboard... Sporting the same processor and complete with a stylus, I was a mystified by your closing statement that "If you’re shopping for an Ultrabook today and want that tablet experience as well, Surface Pro really is the best and only choice on the market." ???Krysto - Wednesday, February 6, 2013 - link
How many times did you redo your battery tests before you got those results, Anand?You usually get lower battery results than everyone else. But now you got some of the highest, while everyone else puts it at like 4h, at most.
$1,000 for a device full of compromises, and thick and heavy as well is not worth it.

I find myself wishing the Surface design team would make a proper ultrabook. It could still be a tablet with a flip back screen like the Lenovo Yoga, just make the form factor an actual ultrabook rather than a tablet with a stand. That way they could integrate a better keyboard and mouse and potentially have a bit more room for battery and cooling.smalM - Wednesday, February 6, 2013 - link
"Once again, with lower power hardware I see Microsoft being able to minimize this - but that’s a topic for Surface 2 Pro."And it will have to compete with the successors of iPad 4 and Nexus 10.
"If you’re shopping for an Ultrabook today and want that tablet experience as well, Surface Pro really is the best and only choice on the market."
That's a really small market place.

Except, Ipad and Nexus can NEVER match a Microsoft tablet in one HUGELY important area for IT professionals, etc etc...x86 compatibility
Dekker - Wednesday, February 6, 2013 - link
> x86 compatibilityTrue, but that brings us to the core question: Is x86 compatibility a killer feature? I'm not convinced. Two reasons:
1) Given that x86 software relies heavily on a keyboard and mouse, it is hard to see how the tablet form factor is going to work. Stuff like building spreadsheets and editing large documents is just torture on a tablet (I have tried and tried). I immediately grab my laptop or MBA.
2) I use my tablet for browsing, email, casual gaming, light photo editing and internet shopping. All of these are easily done with apps, none of which require much investment in time, money or file conversion. In short, x86 is an irrelevance for many types of usage.
While I could see some future for the PRO as a corporate tablet, the lack of LTE/3G must surely be a deal breaker for many.
