Surface Duo 2 vs. Surface Duo: Which is better?

The Microsoft Surface Duo 2 is one of the most interesting phones to launch this year. It’s Microsoft’s unique take on the foldable genre of smartphones, and it advances the concept rather than collapsing into the more consumer-friendly style we see in the Galaxy Z Fold and Galaxy Z Flip-series of foldables. Instead of a single, folding screen, the Surface Duo-range uses two separate displays side-by-side.

While it might be the newest, sometimes the latest isn’t always the greatest. We’re trotting out the original Surface Duo to see if it’s a viable alternative to the Surface Duo 2 by looking at their specs, designs, and overall capabilities. You want a foldable phone from Microsoft? Let’s see which one of these two is the best.

Design, display, and durability

The Microsoft <entity>Surface Duo</entity> 2 is great for multi-tasking.
Adam Doud/Digital Trends

The Surface Duo 2 is a clear evolution of the Surface Duo design-wise. There are a few changes to it that scream 2021 — hello camera bump — but you won’t confuse it for any other foldable. Now, while it does look similar, there are many small changes that make it a better overall device.

The screen is bigger, going from 8.1 inches to 8.3 inches while unfolded and 5.6 inches to 5.8 inches while folded. The display is now covered in Gorilla Glass Victus, making it more durable than the previous Gorilla Glass 5. The screen is still a PixelSense AMOLED display that’s 2688 x 1892 while open and 1344 x 1892 while closed. Microsoft makes very good displays, and the Duo 2 will not disappoint with its 100% sRGB coverage. The display has also been bumped to a 90Hz smooth display, and there’s a small gap when you close the Duo that gives you a strip for notifications.

You can get the Duo 2 in silver — Glacier, as Microsoft calls it. On the other hand, a new Obsidian black finish is here, and nominative redundancy aside, it does look pretty good. New colors are one way that phone makers set aside newer products from older ones, and Microsoft isn’t one to buck tradition.

When it comes to regressions and stagnation, there’s no IP rating on the Duo with this generation, like you’ll find on the Fold 3. The Duo got a little bit heavier at 284 grams, and that camera bump might get in the way when using it on the go.

Winner: Microsoft Surface Duo 2

Performance, battery life, and charging

Microsoft has decided a premium-priced device is worthy of premium specs, and the Surface Duo 2 is equipped with the current Snapdragon 888 processor that powers the best Android phones out this year. The Duo came with an outdated 855, an odd choice for its time. The RAM is going up from 6GB to 8GB, and you’ll be able to stack your device with up to 512GB of storage. Enough to hold all your documents forever.

The original Duo offered a decent battery life, and we were able to keep it going for a day in our review. Our review of the Surface Duo 2 review has shown a similarly strong battery life, with performance being just below the iPhone 13 Pro, and ending a standard day with about 20% left in the tank. Considering it’s powering two screens, that’s a pretty solid performance.

The Surface Duo 2 wins this based on its more powerful hardware.

Going from no camera to three cameras makes this a slam dunk. Microsoft shipped the original Surface Duo with a single front-facing camera that did not perform very well at all. With the Duo 2, all of that is fixed.

There’s a small camera bump at the front, housing a triple set of cameras, as is the norm in 2021. There’s a 16-megapixel ultrawide, a 12MP wide-angle, and a 12MP telephoto lens. You can capture portrait photos, and Microsoft is adding a dedicated night mode.

Video is also getting a big boost here with support for both 4K and slow motion. As we said at the outset, you needn’t compare the Duo to the Duo 2 in hand to know who wins because the Duo simply cannot do what the Duo 2 can do camera-wise.

That being said, we still found some faults with the Duo 2’s camera. It wasn’t the fastest at snapping photos, nor was the orientation particularly convenient. As with most smartphone cameras, it was pretty good during the day with some very good portrait mode, but it fell far behind rivals during the night — especially within its price range.

Video-wise, it’s a miss for us. Whether at daytime or nighttime, Microsoft’s Surface Duo 2 is not the phone you buy for mobile videography, especially if you plan to move while shooting.

It still wins out over the Duo merely by virtue of actually having a camera system, but it’s not as good as it could be.

Winner: Microsoft Surface Duo 2

Software and updates

Jeremy Kaplan/Digital Trends

It’s a tough one to grade. The Duo and Duo 2 both ship with Microsoft’s version of Android, while the Duo 2 comes with the more modern Android 11. The Duo 2 comes with improved multitasking and a mature Android exosystem that takes multi-screen experiences into account, while the original Duo did not have that luxury.

Where it’s hard is on the update scale. While Microsoft promises fast and speedy updates, in practice, the Duo has received fewer updates than your average $1,000 Android phone. This is to say … none. A year after Android 11’s release and a few weeks before Android 12, there’s no Android 11 to be found for the Surface Duo.

Will Microsoft be better at this now that it’s spent some time building for Android? That remains to be seen.

Special features

The Microsoft Surface Duo 2 is the world's thinnest 5G phone.

Two things: NFC and 5G. The lack of 5G could be overlooked, as the standard was yet to fully proliferate when the original Duo was released. The lack of NFC? Not so much. You simply won’t be using Google Pay on the original Duo, a standard that has only grown more widespread as contactless payments have been encouraged.

Sure, you could always buy a secondary phone — but you’re not spending $1,000 on a phone to discard it after a year or supplement it with another; you’re making an investment. The Surface Duo 2 fixes these two really silly omissions, and it’s a no-brainer which to pick.

Winner: Microsoft Surface Duo 2

Price and availability

The Surface Duo is all but sold out worldwide. That said, it’s not worth paying for at this time. Though you will undoubtedly get deep discounts on it — Woot sells it for $400 at times — the compromises are just not worth it. Whether it’s the lack of a proper camera or the old software, it’s not worth its asking price. If you want to give Microsoft’s software a fair shake, the newer Duo 2, while far more expensive, will be the better buy.

Microsoft is making this available unlocked for all carriers in Australia, Canada, France, Germany, the U.K., and the U.S.

Winner: Microsoft Surface Duo 2

Overall winner: Microsoft Surface Duo 2

If there was any phone that had an easier time to do a much better job with its sequel, it was the Surface Duo 2. Microsoft’s first Surface Duo was very flawed. Odd omissions such as 5G and NFC made the device hard to recommend for casual users, and its form factor stood at odds with what we would normally expect from foldables.

The Surface Duo 2 stands out from other foldables, but it mixes its bold choices with sensible ones. The Surface Duo 2 is a complete upgrade over its predecessor. The first Surface Duo is an interesting device from the perspective of the evolution of smartphones — but you probably shouldn’t buy it.

Is the Nothing Phone 2 waterproof?
The Nothing Phone 2's camera module with the lights lit up.

Nothing may be a newcomer to the smartphone scene, but it really made an impact with the Nothing Phone 1. Debuting last year, the Phone 1 brought a unique design, good specs, an affordable price, and of course, the Glyph lighting system. Now, the Nothing Phone 2 is here, complete with the Glyph lighting system and some extra new tricks to tempt you into Nothing's bustling ecosystem.

But the Nothing Phone 2 has more going for it than just a fancy lighting system, and those looking for a strong specs sheet won't be disappointed. Nothing's new phone has an adaptive refresh rate that peaks at 120Hz, up to 512GB of storage, 12GB of RAM, and the powerful Snapdragon 8+ Gen 1 processor. But how durable is it? Water resistance has become a feature we really want in smartphones, as it means phones are better insulated against the damage caused by accidental slips into baths, pools, and even toilets. So, is the Nothing Phone 2 waterproof?

Is this our first look at the OnePlus Fold? I sure hope so
Purported front and rear view of the OnePlus V Fold

OnePlus recently gave a teasing glimpse of its first foldable phone. Well, that glimpse was actually turned into a high-resolution view of the upcoming device, thanks to leaker @OnLeaks (via SmartPrix). The leaked renders of the upcoming OnePlus Fold show a device that is unmistakably OnePlus, with some standout design touches and a promising camera perk.

But a word of caution before you start digging into your wallet. The leaked renders are reportedly based on “a prototype unit in the testing stage,” which means the final version hitting the shelves later this year might look a tad -- or maybe entirely -- different.

The Nothing Phone 2 just leaked, and it’s not what I expected
Nothing Phone (2) leaked render.

Nothing has been hyping up It’s next phone with executive interviews and social media drop-feeding recently. But merely weeks before the anticipated July launch and eventual brand arrival in the U.S. market, the leaking world has spoiled the design surprise.

Prolific leaker Steve H. (aka @OnLeaks ) teamed up with SmartPrix to drop high-resolution renders of the Nothing Phone 2 based on a “testing stage unit.” To sum up my first impression after seeing these renders, I’d say it’s underwhelming — especially for a brand that takes a lot of pride in its design chops.
