Oneus 3 review: Third time’s the charm with this supercharged, unlocked flagship

Oneus has officially grown up. ereas a year ago we might have had to endure a series of callow online advertisements telling us to “Never Settle,” this year we’re seeing a bit more humility from the smartphone startup. It’s especially apparent with the launch of the Oneus 3, which is hs-down the best smartphone Oneus has ever produced.

ed, this isn’t a particularly major feat for Oneus, since it’s only manufactured three other smartphones. But it’s nice to see the company put less emphasis on excessive buzz-building instead focus on delivering a premium product that’s worth its $400 price tag, doesn’t skimp on essential features—unlike last year’s release.

Third time’s the charm

The Oneus 3’s chassis design might look a little familiar to you.

It might have taken three hardware releases to get here, but the Oneus 3 is a stunning phone. It’s got a stylish aluminum glass chassis that’s a little Apple a little HTC, but Oneus’s unique flair is all there—right down to the barely-there bezel.

The Oneus 3 is one of the most comfortable phones I’ve held in a while.

oking for a thinner phone than the Nexus 6 The Oneus 3 is it, albeit marginally.

The Oneus 3 is also one of the thinnest phones I’ve held in a while (though not as thin as the upcoming Moto Z). It somehow makes even the Nexus 6look bulky, despite the fact that both phones measure in at 7.3 mm thick. I especially appreciate that the official Oneus back covers don’t add much bulk the way that the 6s cases do. Indeed, the Oneus 3 will stay svelte as long as you don’t mind leaving it a little exposed.

The Oneus 3’s back cover comes in five different varieties. This is the bamboo model.

The fastest fingerprint scanner I’ve used since the Nexus 6

As featured on its predecessor, Oneus brought back the recessed fingerprint scanner that doubles as a Home button. It’s just as responsive as the rear-facing scanner on the Nexus 6 all it takes is one quick thumb-press to load up the Home screen.

The alert switch is my saving grace when I’m trying to avoid phone calls. 

The Oneus 3 also features a small alert switch. It makes it a cinch to switch between silent mode “let-everyone-bother-me-at-all-times” mode without unlocking the phone. You can customize exactly what your alert modes do— who they shut out—in the Settings panel.

The Oneus 3’s 5.5-inch 1080p AMOD display can be strikingly bright at night, so you’ll want to shield your eyes with the help of the phone’s Night mode, which lives in the Quick Settings. This setting skews the display color to a warmer hue so that it’s less stark, thus making it more comfortable to catch up on your Twitter feed before bed. The Oneus 3 also offers an ambient display like the Nexus 6 it lights up when you get a new notification or pick up your phone, but isn’t lit all the time like that on the Galaxy S7 or G5..

A little more RAM goes a long way

The Oneus 3 runs on the same Qualcomm Snapdragon 820 processor as its competition, though it packs more of a punch, thanks to 6GB of RAM. That much memory might seem like overkill, but not once did the RAM-intensive Snapchat app crash on me as I attempted to make silly videos of my weekend at home. That’s pretty impressive considering the app crashes constantly on my Nexus 6 even on the pristine Galaxy S7, which uses the same processor.

The Oneus 3 is a workhorse for multi-taskers thanks to its extra bit of RAM.

l four of these flagships run on the same SoC. It’s nice to see that OEMs didn’t have to choose between overheating or being underpowered, as was the case last year.

The Oneus 3’s benchmark numbers reinforce my anecdotal experience. It hily outperformed the Galaxy S7 ge in , marginally in GFXch. It was also on par with the rest of the year’s flagships across the board, including the HTC 10 G5, all of which are also driven by the Snapdragon 820. I like that Oneus shoved in the extra RAM, too, because it future-proofs the phone for whatever lies ahead. It’s like plopping in a few extra sticks of memory into your for performance posterity.

The Oneus 3 will get you through a day’s work, then some.

The Oneus 3 exhibited stellar battery life. The device’s 3,000mAh battery pack outlasted all three of this year’s marquee flagships in ’s battery test, though it trailed behind them in Geekbench. For the most part, I had no problems getting through the day with the Oneus 3 in tow, though it’s definitely a battery sucker if you have the screen set at a high brightness.

Oneus still hasn’t opted for wireless charging (that’s tough to do with a metal body), but it does bundle in a new feature called DASH Charge, which places the charging chip inside the power adapter rather than inside the phone’s port, as is the case with other devices. The upshot is the phone won’t throttle down performance when you’re using it while charging.

th the compatible charging cord adapter, Oneus advertises that the Oneus 3 can replenish 60 percent of its battery life in just half an hour. I can confirm this: I sat counted as the Oneus 3’s battery meter went from nothing to 63 percent in 31 minutes. It’s like Qualcomm’s QuickCharge 3.0 on speed. The only bummer is that this is proprietary technology that only works with Oneus’s devices, so you’ll have to turn to its online store to purchase DASH compatible car chargers battery packs.

Reliable camera performance

Oneus’s camera capabilities have been pretty solid over the last two generations, I’m happy to report that the Oneus 3’s 16-megapixel rear-facing camera is on par with today’s competition. Though its aperture is set at f/2.0, I was impressed by the device’s ability to shoot low light scenes without the aid of a smartphone tripod or manual mode.

The Oneus 3 opts for a white balance that is slightly more red, less green, than the Galaxy S7.

I actually prefer the Oneus 3’s low light result, despite the fact that the Galaxy S7 ge is shooting at a larger aperture of f/1.7. The latter is a clearer picture, but I like the white balance on the Oneus 3’s result a little more.

BART you’re there. If you zoom in, you can see the Oneus 3’s attempt to keep the pixels intact as it shot in lower light.

Zoom in to this photo to see how sharp the branches on the tree are—an impressive feat from a non-Samsung bred device.

I could work with the low light abilities of the Oneus 3. I like that there’s some detail—albeit grainy—in this moody picture.  

At times, Oneus’ post-processing engine is prone to over-processing. Nonetheless, there’s a Manual mode available with RAimage support if you’re aching for more granular control. so, the Oneus 3 employs both optical image stabilization (OIS) electronic image stabilization (EIS), which helps ensure that both photos videos are clear sharp.

My favorite part of the Oneus 3 is the 8-megapixel front-facing camera. I appreciate higher resolutions for the front-facing camera because every camera app can take advantage of these extra megapixels. I also like that there aren’t any beautifying features bloating up the software, as is the trend with other Android devices. There are plenty of third-party apps that can give us the airbrushed look, so this trick doesn’t have to be built in to the camera software. The Oneus 3 also has a neat feature that starts a countdown once you smile; this should make group selfies easier to take. You don’t even have to flash your teeth for it to work.

Stock Android with flair

I can’t believe it’s not uncher.

The new Oxygen OS 3.1.1—which updated to 3.1.2 during my testing—is a beefed-up version of the operating system we first met in last year’s Oneus 2. It still features a Shelf, which you can access by swiping right on the Home screen, it still offers the same array of customizable options in the Settings panel. You can even tweak a variety of interface elements, like which icons are displayed in the status bar, whether to enable soft navigation buttons or physical ones.

The Shelf is a nice customizable ling page if you’re not too keen on the busyness of Now.

Don’t like all the icons crowding your status bar? No problem, you can eliminate them— more—in the settings panel.

Customizable gestures are also available for the Oneus 3. For instance, you can choose what happens when you long-press or double-tap either of the navigation buttons. I set up the Home button to launch the camera with a double-tap, the Recents button to open my last-used app with a long-press. This is a feature that we’ll eventually see in Android N, but it’s nice to see it included here, too. And you don’t have to worry about being left behind: Oneus is already working on its version of Oxygen OS for the next release of Android.

Oneus’s commitment to customization is appreciated. And if it turns out you’re not particularly keen on Oneus’s interpretation, you can always install another launcher have access to all the same wonderful customization options.

Should you buy it?

If you’re tired of all the Samsungs in the marketplace, give the Oneus 3 a try.

It took three tries, but Oneus finally has a flagship that lives up to some of its absurd marketing slogans. And the best part is that you can buy this smartphone outright without having to jump through hoops to secure an invitation. That’s right: Oneus is doing away with its invite-only system, its online storefront is open to anyone who’s interested. This should help the company achieve more success among mainstream smartphone users, not just hardcore Android enthusiasts with the inside scoop.

Unfortunately, the Oneus 3 is not compatible with all four major U.S. carriers. You can’t use it with Verizon, but for $400 unlocked, the Oneus 3 is a seriously great deal for those on T-Mobile or AT&T.

If Oneus’s goal is to be a major player in the smartphone wars, it’s getting there—slowly but surely. th its newly refined hardware decision to dump the antiquated invite-only system, Oneus may be well on its way to a successful smartphone launch. It may never be the “flagship killer” we were once promised—that ship has passed—but it is a solid choice for your daily driver.
