“The Surface Pro 4 is the best 2-in-1 PC we’ve ever tested.”
  • New Type Cover is wonderful
  • Pen is standard and works well
  • Pixel-dense display
  • Strong performance in all areas
  • Still heavy compared to dedicated tablets
  • Battery can drain quickly in real-world use

Update on June 19 2017 9:40AM by Matt Smith: The Surface Pro 4 has been replaced by the Surface Pro, which we’ve reviewed. Microsoft’s new Surface Pro is slightly thinner, has superior battery life, and significantly outperforms the Pro 4 in processor benchmarks. You may still find the Surface Pro 4 for sale, but it should only be purchased at a hefty discount. 

The original Surface Pro was bulky. Its battery was limited. The keyboard was annoying, the display wasn’t great, and performance was just okay. It was expensive. Worst of all, it was forced to run Windows 8, an awkward operating system poorly suited for dedicated touchscreen use.

Yet, for all its faults, the Surface Pro was also revolutionary.

If Microsoft was as stodgy as its reputation suggests, it would’ve given up on the Pro and set its sights on some other pie-in-the-sky project. Instead, it hunkered down, analyzed the problem, and tried again. And again. And again. After just two and a half years we’re now on the fourth iteration. On average, a new Pro has arrived every eight months.

The Surface Pro 4 is a microcosm of the change Microsoft is trying to spur inside its own walls.

A look at the latest model’s specifications makes the improvements clear. Aside from a move to Intel’s 6th-generation Core chips – significant, because Microsoft skipped the fifth generation entirely – the new model has a long list of updates. The keyboard is more spacious, the touchpad is larger, the display is both bigger and more pixel dense, the pen is more sensitive, and the base hard drive offers twice the capacity as before.

But the Surface Pro 4 also finds itself competing in an increasingly diverse field. Its revolutionary nature has forced other companies to respond. Since its release, the Surface Pro 4 has been constantly imitated, but no updates in almost a year has left the Surface Pro 4 in the shadow of its former prominence. Is it still a solid choice, or should you hold off for an upgrade?


Microsoft is obviously comfortable with the design of its Surface notebooks. Like the less powerful Surface 3, which debuted over the summer, the Pro 4 doesn’t look much different than its predecessor. The new model is a hair thinner, and a few hundredths of a pound lighter, but its dimensions are otherwise the same.

The Surface Pro 4 is still bulky for a tablet. Virtually everything based on mobile hardware is thinner and lighter, even the iPad Pro, which has a similar display size. For a PC tablet, though, the Surface Pro 4 is pretty svelte.

Whether it’s small enough depends on how you plan to use it, and perhaps even your own dimensions. People who find a regular iPad a bit unwieldy are going to find this massive. We managed alright. More recent competitors like the Samsung TabPro S and Huawei Matebook indisputably feel slimmer in-hand, and are easier to handle. But the Surface Pro 4 is a lot easier to handle than any 2-in-1 with a 360-degree hinge, like Lenovo’s Yoga series, and that’s become the much more common implementation.

Microsoft has set up the Pro properly for use as either a PC or tablet. Though its overall size has hardly changed, the new model jumps from a 12-inch to a 12.3-inch display. That’s accomplished through thinner bezels which look more attractive, but still provide enough room to grip the Surface Pro without grazing the touchscreen.

The device also benefits from thoughtful location of buttons. The power and volume keys are located on the upper left edge when the device is held in landscape orientation or used as a PC. That becomes the upper right flank when it’s turned and used in portrait orientation, which is typical for tablets. In either case, the buttons are accessible, yet not positioned where they’ll be accidentally bumped.

Using the stylus is as intuitive as using a real pen.

Connectivity is a bit more awkward. The USB and Mini-DisplayPort jacks are on the right flank when the Surface Pro is used with the keyboard. That works well enough, but it means anything attached will jut out from the bottom if the device is used as a tablet in portrait orientation. The combo headphone/microphone jack is difficult in either case, as its always located near the top edge of the device, leaving the user to tangle with the cord. There are only so many places to put a port on a slate.

The power brick’s connector works well. Its magnetically aligned and multi-directional, so it’s easy to insert and doesn’t send the entire device flying if you happen to trip over it and tug it out. It’s past time for this type of design to become the standard for both tablets and laptops, but most of the Pro 4’s PC competition is saddled with a stiff, stubborn plug. Better still, the brick itself offers a USB port, so you can charge your phone without using the USB 3.0 port on the Surface Pro 4 itself.

Type Cover triumphant

Keyboard quality has long been our most serious issue with the Surface Pro line. Microsoft always used a strange keyboard layout that lacks significant gaps between keys, making it more difficult to discern between them. Previous Type Covers also made poor use of the available space, so both the keyboard and touchpad weren’t as large as they could be.

The new Type Cover – which is compatible with the old Surface Pro 3, by the way – entirely fixes the problem. It better uses the available space, so it’s larger and offers plenty of room between keys. The touchpad is bigger, especially in height. Like the previous version, the new Cover is powered over a simple connector that attaches magnetically, and it can be used flat or propped at an angle for a more ergonomic experience.

The improved Cover transforms the Surface Pro. The Pro 3’s cover asked the user to bargain with it. “Okay, kid,” it said, “I’ll give you a touchscreen, but you gotta put up with this keyboard.” The Pro 4 asks no such compromise. It works as well as most dedicated laptops and has a major edge over many competitors including the iPad Pro, Samsung TabPro S, and Huawei Matebook, all of which feel flimsy by comparison. The Lenovo ThinkPad X1 Tablet is the only device we’ve tested that beats the Surface Pro 4’s Type Cover.

Lenovo’s X1 wins mostly because it’s more comfortable on your lap. Microsoft’s adjustable hinge needs a flat surface to be stable. That can be a problem if you want to mash the keys while reclining on your sofa to enjoy an episode of Deep Space Nine. Microsoft contends this issue isn’t a big deal because laptops are actually used on a tablet or desk the majority of the time, and for the most part, that’s true. But it can be annoying – even damaging, as a shift in posture can send the unsteady Pro 4 tumbling off your lap and onto the floor.

The pen is mighty

The pen, too, has been improved. It has four times the sensitivity of that which shipped with the Surface Pro 3. It also includes a “real” eraser that works just like you’d expect it to. While the older model looked as if it had one, it in fact used a button, a design that went against decades of muscle memory.

These changes are a big upgrade – the eraser, especially. Microsoft’s software has continued to mature, as well, so pen input works far more smoothly than it did with the original Surface. Now, for the first time since its launch, using a stylus doesn’t feel like a constant hassle. It’s handy and, when using the Surface Pro 4 as a tablet, often preferable to the virtual keyboard.

Some issues do persist. If you stay in Microsoft’s eco-system of apps, like Edge and OneNote, the pen works almost without flaw. Third-party applications are not always as compatible. The Google Chrome browser, for example, absolutely refused to initiate pen input in any of its text entry fields. Slack, an organization app used by companies worldwide, seemed finicky about detecting the pen’s “clicks.” And if you were hoping to play games with touch or pen input, forget about it. Very few are properly designed for it.

Still, the Surface Pen is arguably the best in the business. The pen itself is well balanced, feels sturdy, and places its button in locations that are ergonomically comfortable. But what sets it apart from others is that Microsoft doesn’t intend the Surface to be used without the pen (with most competitors, the stylus is an optional add-on). That means Microsoft can aggressively design features that benefit it. Microsoft’s Windows 10 Anniversary Update — the first big update to Windows 10 — is a great example. Windows Ink, its headline feature, is all about the pen.

When you’re not using the pen, it can be stowed magnetically on either flank of the Surface Pro 4. We’re still not happy with the security of this approach, as the pen is a bit too easy to knock off. We can imagine plenty of disasters involving errant limbs that send the pen flying into drinks, sewer grates, or food processors. The pen can be clipped in the Type Cover when it’s closed, instead, and that’s the more secure option.

The display receives an unnecessary, but appreciated, upgrade

The Surface Pro 3’s screen was not a weak point of the device, but Microsoft decided to improve it anyway. Aside from the increase in size from 12 to 12.3 inches, the display has upped its pixel count to 2,736 × 1,824. That’s 267 per inch, which is far more than needed when the Surface is used as a laptop. It’s still not the best in the tablet category, but it beats most, including the iPad Pro.

The new Type Cover is a huge leap over the previous, and better than some laptops.

There’s a lot more to the screen than pixel count, and the new Surface nails the details. We recorded a high maximum brightness of 349 lux alongside a maximum contrast ratio of 940:1. Most figures are among the best we’ve recorded from any laptop, tablet or 2-in-1. Color accuracy was the only soft spot, as the average difference of DeltaE 6.49 was high.

All these results are good, but the competition isn’t giving Microsoft an easy time. Samsung’s TabPro S is the standout. It’s the first 2-in-1 with an OLED display, and its contrast ratio is off the charts. The Dell Latitude 12 7000 Series 2-in-1, Lenovo ThinkPad X1, and Vaio Z Flip also manage to beat the Surface Pro 4 slightly in color gamut, contrast, and overall color accuracy.

Our impressions were as expected based off the results. A high contrast ratio should mean the appearance of deep black levels and brilliant whites, and the Surface Pro 4 delivered, creating a sense of depth in movies and images. The color issues made themselves apparent, however, through poor reproduction of skin tones. Actors often looked more like wax figures rather than real people.

That said, we’re picky about color, and we doubt most would notice. The Surface Pro 4’s high contrast and pixel density, on the other hand, will be obvious to anyone.

I’m a Surface, hear me roar

Despite its small size, the speakers in the Surface Pro 4 made an impact. They were loud at maximum volume and produced clear, crisp audio with minimal distortion, even in bass-heavy music. Human voices were reproduced with particular clarity, which makes sense. This is a business machine, after all, and Skype is useless if others can’t be heard.

Skylake rises to the top

The Surface Pro 4 makes several important hardware changes over the Pro 3. It can equip up to 16GB of RAM, instead of 8GB, and the base hard drive now offers 128GB instead of 64GB.

Those are nice upgrades. The base model has received an arguable downgrade, however, because it now has a Core m3 processor rather than a Core i3. Whether that’s a downgrade is arguable because the m3 represents a trade-off. The base clock is only 900MHz, and its graphics component is weaker than other Core chips. But battery life may improve as a result of the power-sipping chip.

We can’t tell you more than that. Microsoft predictably shipped the mid-range Core i5-6300U pair with 8GB of RAM and a 128GB hard drive. We threw the chip into our benchmarks and found it a strong, if not exceptional, performer.

There are clearly two tiers of results here. One is represented by the Core i5 and i7 chips in the Surface models, and the Vaio Flip Z. The other, slower tier is shown by the Core m3 and m7 chips in the Lenovo, Huawei, and Samsung.

The Lenovo ThinkPad X1 tablet does keep up and even exceed the Surface Pro 4 with Core i5 in the Geekbench and 7-Zip tests. However, the ThinkPad’s weakness is revealed in Handbrake, a sustained video encoding test. Under that scenario the ThinkPad, along with Huawei’s Matebook, comes up against the limitations of its Core m7 chip, and finishes substantially behind the Surface Pro 4.

In brief, the Surface Pro 4 with Core i5 performs much like any laptop with the same chip. It’s plenty quick, but doesn’t set any records.

A solid, solid state drive

Our Surface Pro 4’s 256GB solid state drive also did well in benchmarks. CrystalDiskMark’s sequential test recorded an average read speed of 928 megabytes per second and an average write of 449MB/s.

Those figures are not the best we’ve seen, but they’re near the leading edge. Only the Vaio Flip Z substantially outperformed the Surface Pro 4.

Not great for games

Gaming is not something the Surface is built to handle, but it does have the relevant incarnation of Intel’s mainstream mobile graphics, in this case called Intel HD 520. Like the processor itself, the IGP produces respectable but modest results.

Once again, the two tiers of performance are visible. The Samsung TabPro S and Huawei Matebook fair badly, and even the Lenovo can’t catch up to the Surface Pro 4. But there’s also a third tier, one the Vaio Flip Z sits claims as its own. Its Core i7 came with Intel’s HD 550, and it proved a big step up from HD 520, delivering a boost of 75 percent.

The Surface Pro 4’s integrated graphics can launch most modern games, and will deliver a tolerable experience in some if detail is kept at medium or low. Don’t expect to play any recent titles at high detail, and the most demanding games will be playable only if in-game resolution is reduced to 720p – if they’re playable at all.

Small device, small battery

The Surface Pro 4 isn’t going to throw your back out, as it weighs about 1.7 pounds without accessories, and just over 2.3 pounds with Type Cover and Pen included. Its light weight, combined with its slim profile, makes it easy to chuck in a bag for a trip. Even the power adapter is small.

A large 38 watt-hour battery provides juice on the go. That’s a respectable capacity, but the high-resolution display sucks down power, so the Pro 4 quotes the same nine-hour maximum as the Pro 3.

We had some problems in our real-world tests. In one instance we managed to squeeze six hours and a half using the Peacekeeper browsing benchmark. However, on other occasions we drained the battery in three and a half hours using a simple web browsing and YouTube viewing loop.

In any case, the promised nine hours is optimistic, as the Pro 4 fell well short of that in every test scenario. Our subjective experience was the same, as we found the device can’t handle a work day on a single charge. Instead it falls well short, often lasting barely more than half a day. On one short-lived occasion we worked on several open Word documents while also slacking off by watching YouTube videos. That killed an entire charge in under three hours.

Many of the Surface Pro 4’s competitors face similar issues. The Peacekeeper web browsing benchmark killed the Huawei Matebook in three hours and nine minutes, while Lenovo’s ThinkPad X1 Tablet lasted just three hours and four minutes. This is one area where the iPad Pro remains the undisputed champion, as it lasted almost nine and a half hours under the same test.


The Surface Pro 4 is covered by a one year limited warranty against manufacturer defects. Further warranty extensions are available as an option. This, of course, is standard for the industry. Very few laptops come with more than a year of standard coverage.


Editor’s note: The Surface Pro 4 is no longer the most recent model. Its successor is the Microsoft Surface Pro, which beats the Pro 4 in battery life, processor performance, and other areas. 

The Surface Pro 4 is a microcosm of the change Microsoft is trying to spur inside its own walls. Time and time again, it missed the opportunity to leap on a new trend in consumer technology. But not with Surface. This time, Microsoft is a leader. It’s setting the trend. And unlike its new competitors, it’s had a few years to work out the kinks. Though it’s not perfect, the fourth incarnation of the Surface Pro is a great piece of hardware, and easily defeats every other 2-in-1 currently available.

No one master stroke is responsible. Instead, the Pro has grown through evolution. Numerous bits, from the keyboard to the power charger, have changed little by little. The original Surface Pro had serious flaws. The second and third versions were good, but still demanded compromise. The fourth incarnation overcomes the limitations of its predecessors without sacrificing the core mission. It’s a true do-it-all-device.

With that said, no one will call the Pro a bargain. The base model is $800 without the keyboard. Microsoft no longer sells our review unit, but the comparable performance model rings up at $1,200. That’s a lot of money, and anyone looking at the Surface still needs to ask themselves if a single do-it-all device is really needed. It’s also been quite a while without an update, so it should only be under consideration if it’s available at a discount.

Still, the Surface Pro 4 fits snuggly in the niche Microsoft envisioned for it. Its combination of reasonable speed, decent display, and excellent Type Cover make for a 2-in-1 that’s well-suited for the life of those who live by the motto “work hard, play hard.”

Microsoft’s Surface Duo gets a Windows-style refresh with Android 12L
Surface Duo 2 on a textured background.

Microsoft is finally updating its Surface Duo -- ahem -- duo to Android 12 this week. The company broke the news on its official Microsoft Devices Blog after previously committing to rolling out an update sometime this year. Android 12 was made generally available by Google in October 2021, while Android 12L hit Pixels in March.

The star of the show here is Android 12's big visual refresh. Yup, Material You, dynamic color theming, and more are coming to the Surface Duo phones. The company as even throwing in four new wallpapers to highlight the refresh. However, Microsoft is going a step further by redesigning the Duo's software so that it'll look a lot like Windows 11. This is pretty obvious in that the system settings app and notification center now resemble Windows 11's versions of those features, and there are a lot of fluent design (Microsoft's design language) touches hidden in the company's preinstalled apps. In other words, the Surface Duo and Duo 2 pair are becoming true Windows phones. Of course, this illusion disappears when you dip into third-party apps, but if you're buying a Microsoft Duo, you're almost certainly a superfan.

This is the secret Surface Duo that Microsoft never released
The Microsoft Surface Duo 2 rests on a staircase railing because: right angles.

An archived eBay listing has revealed pictures of an unreleased Microsoft Surface Duo. The device was supposed to debut as a midrange version of the Surface Duo 2. However, it never made the cut and was canceled later in 2021.

Windows Central, reports that the unit was listed as a Surface Duo 2 “dev unit.” While the listing is no longer available, the details were sourced in time to give us a closer look at what could have been the “Lite” version of the second-gen Surface Duo. In the images, the device appears to a rocking a matte plastic finish. It has slightly more rounded corners and — more importantly — has a lesser elevated camera bump as compared to the Duo 2.
