OnePlus 6 review: The most perfect OnePlus phone yet

The OnePlus 6 is a definite upgrade over the OnePlus 5T, but since it's launched just around six months after the 5T, it makes little sense for 5T or for that matter, even the OnePlus 5 users to make the switch.

In the smartphone world, there are only a handful of annual phone launches that are of any significance. Apple's market-defining iPhones aside, the only other phones that matter are the Samsung Galaxy and Google Pixel series of phones, and of course, OnePlus.

 OnePlus 6 review: The most perfect OnePlus phone yet

OnePlus 6

OnePlus has managed to carve a niche for itself and almost single-handedly created the so-called budget-flagship segment. OnePlus has managed to succeed because it's found a way of offering a phone with 80 percent of flagship phone features at 50 percent of the price.

With the likes of Huawei and Xiaomi now muscling their way into this segment, however, OnePlus is in for a tough fight.

Build and Design: 8.5/10

The first thing that immediately comes across is that the OnePlus 6 is quite a handful. OnePlus wanted to get maximum display area, and to that effect it has employed a massive 6.28-inch FHD+ optic AMOLED display. There used to be a time when this would almost go into the tablet or, more recently, phablet category. But considering most smartphones these days cross the 5.5-inch display threshold without batting an eyelid, that nomenclature of a phablet has disappeared from our tech lexicology.

OnePlus has used Corning Gorilla Glass 5 on both, the front and the back. And the back, well it's easily the most gorgeous looking device after the Huawei P20 Pro that we've seen in recent times. The choice to use Midnight Black reminds one of the now discontinued OnePlus X, the variant with the ceramic back. But unlike other devices, the glass back on the OnePlus 6 is not meant for wireless charging. And since it is a glass back, it also tends to collect a lot go fingerprints, so keeping a microfibre cloth handy to clean the smudges will be a given. The only solution is snapping on the silicon cover which comes bundled with the phone or snap on any custom cover of your choice. But with this gorgeous a back, you'd want to show it off. However, the glass back also means that you've to be very careful when using it, as a fall will likely shatter the rear glass.

OnePlus has retained the horizon line design which was seen in its previous phones as well. Even the base of the OnePlus 6 comes with a very gradual slope.

The bottom of the phone houses the mono speaker grille, a USB Type-C charging and data transfer port, microphone and a 3.5 mm audio jack. Kudos to OnePlus for retaining the headphone jack. But there are no bundled headphones – cost cutting can't be an excuse, OnePlus.

The position of the alert slider has undergone a shift. You now have it just above the power/standby button on the right hand edge. It's functions remain the same. You still can't program it the way you want. But it still retains that textured finish and the sturdy mechanism. The volume rocker button is on the left hand edge and just above them, you have the dual SIM card slot. The top edge is clean and houses only the microphone. You do notice the antenna lines on the left and right-hand edge.

The display does come with a notch and is accompanied by a chin, but without any fingerprint sensor, as that's been moved to the back. The notch only houses the earpiece speaker and the front facing camera, so don't expect any fancy iPhone X-like depth-sensing capabilities.

The glass-backed rear of the OnePlus 6 beautifully curves just around the edges to merge with the metal frame. There isn't any sharp edge here, and neither are there any on the front, where the frame meets the glass. You get a dual camera setup with the cameras arranged vertically – 16 MP primary camera with OIS on top and a 20 MP secondary camera below it. A dual LED flash unit is present below the cameras and this is followed by the curved rectangular fingerprint scanner. The OnePlus logo is aligned in the centre just below the fingerprint scanner.

In the design department, OnePlus 6 definitely ticks all the right boxes, except for one glaring omission – IP XX certification. Most modern flagships today are either rated for IP67 or IP68 water and dust resistance. This is a guarantee of water and dust resistance, within certain parameters. Since the OnePlus 6 doesn't come with a certification, it's either not qualified for either spec or simply wasn't sent for certification. In fact, the lack of IPXX certification was among the few complaints we had about the OnePlus 5T.

OnePlus does address this partially by claiming that the phone is resistant to water splashes.

Features: 8/10

As is the case with most OnePlus devices, the company has gone all out as far as specs are concerned. You have the Qualcomm Snapdragon 845 SoC, which has an octa-core processor (Kryo 385 cores clocked up to 2.8 GHz) and graphics provided by an Adreno 630 GPU. The Snapdragon 845 SoC also houses the Spectra 280 image signal processor, Hexagon 685 digital signal processor and the Snapdragon X20 modem among other modules. The model we got for review came with 8 GB RAM and 128 GB storage. There is no provision to expand the storage and you get around 105 GB of usable storage.

The OnePlus 6 features a whopping 6.28-inch Optic AMOLED display, which comes with a notch on the top and a chin at the base. On the rear, you have the fingerprint sensor above which are arranged in a vertical alignment the dual cameras of the OnePlus 6. There’s a 16 MP primary camera which is supported by a 20 MP secondary camera. The pixel size on the 16 MP primary camera is 1.22 micron, whereas that on the secondary camera is 1 micron. On the front, you get a 16 MP selfie camera.

In terms of connectivity, there’s a USB Type-C port (with USB 2.0 speeds) for data transfer and charging, Wi-Fi 802.11 a/b/g/n/ac, Bluetooth 5.0 with aptX HD support, GPS with A-GPS and GLONASS and there’s support for NFC. The package is completed with a 3,300 mAh battery under the hood, which is the same as on the last generation OnePlus 5T. There’s no support for wireless charging despite the glass back, but you still get Dash Charging (which OnePlus is now calling fast charging for trademark reasons) support.

Display: 7.5/10

The OnePlus 6 has one of the largest displays on a smartphone today. The only phone which had a larger display than the OnePlus 6 (6.28-inches) was the Xiaomi Mi Max 2, which arrived with at 6.44-inch. Do note that the Mi Max 2 offered a screen in an 16:9 aspect ratio, which is broader than OnePlus' 19:9 display. In other words, the Mi Max 2 offers significantly more screen real-estate than the OnePlus 6.

Because the OnePlus 6 has gone with the 2018 trend of thin bezel designs, it has managed to fit it in a comparably smaller footprint. It supports a Full HD+ resolution of 1080x2280 pixels, which gives it a pixel density of 402 PPI, which seems low when compared purely in terms of numbers with the 500+ PPI seen on the likes of the Samsung Galaxy S9 and the Google Pixel 2 XL. Of course, 400 is still much higher than Apple's 300 PPI Retina displays, so there's nothing really to complain about here.

The display may seem to have lower resolution when compared to other Android flagships, but I did not find that to be an issue. I didn’t notice any pixelation, even on close viewing, and the text is sharp even at the lowest font size. When I first unboxed the device, I immediately noticed a bluish tinge on the display. To change that, head over to Settings > Display > Screen Calibration and choose from Default, sRGB, DCI-P3, Adaptive mode and Custom Colour. I selected the DCI P3 mode as that looked the most pleasant to me, but you have a choice to select which one you want. But unlike us geeks, regular users may not know of these options and it would be better if OnePlus asked users to pick a profile during, say, the initial setup. After selecting the DCI-P3 profile, I didn’t notice any major issues.

The brightness is fine indoors, but when I was in bright outdoors, I found it to be a struggle to be able to compose and frame photographs thanks to the reflective display. The sunlight legibility could certainly have been a lot better, and this should definitely be checked in future updates. Barring this issue, I found the display to be quite pleasant. While watching movies and gaming, the AMOLED display certainly helps in delivering a punchy output with excellent contrast levels.

A notch is present at the top with a chin at the base. It is protected by Corning Gorilla Glass 5.

OS and Software: 8/10

OnePlus 6 comes with Android 8.1 out of the box and it has the OxygenOS 5.1.3 skin atop it, and you get the May 2018 security patch. Google had announced at I/O 2018 that OnePlus would be among the handful of brands getting an Android P beta OS for testing. This will be available to all users when the device goes on sale, confirmed OnePlus.

The OnePlus 6 UI includes some iPhone X-like gesture to go with the notch

The OnePlus 6 UI includes some iPhone X-like gesture to go with the notch

As has traditionally been the case with OxygenOS, OnePlus has stuck very close to the stock Android experience. But as if copying the notch from the iPhone X design wasn’t enough, OnePlus has also aped the gestures that were originally implemented in iOS 11 for the iPhone X. You can opt for a navigation bar or a gesture based interface, the toggle for which you'll find under the Settings menu. If you opt for gestures, here's what you can do:

For the Home screen, you swipe up from the bottom-centre edge of the screen; for Recent Apps, you swipe up from the bottom-centre edge of the display and pause; for going Back, you have to swipe to the left or right-hand side of the bottom of the screen. To be really honest, I found this navigation via gestures really gimmicky and defaulted back to the fixed navigation bar. Sacrificing that bottom display real estate will not dramatically change things.

That notch divides the top portion of the display into two parts, but in case you do not want to see the notch, then there is an option to black it out. I don’t understand why companies bother with a notch design if they are going to offer an option to get rid of the notch, but it’s good to at least have an option. Most of the apps that I used were well optimised for the notch, so that was refreshing. You can also go to individual apps and change their display settings so that they cover up the notch if you so want. The display real estate argument sounds weak when you also see a chin at the base. And it's not like the notch-free Samsung Galaxy S9 is the ugliest phone in the market.

Now generally with the notch, the left side shows notifications and the right shows quick settings indicators. Unlike Apple, swiping from either side will display quick settings as well as notifications in the usual Android drop-down menu.

The other major feature in the software is 'Gaming Mode'. Now this isn’t your run of the mill gaming mode which overclocks your GPU frequency or mutes notifications. The Gaming Mode on the OnePlus 6 optimises background resources to work in favour of a game by ensuring processing and network resources are focused on the game. This is in addition to the option to switch off notifications – except those from certain contacts you have given the express permission to do so.

Although the position of the Alert Slider has switched from the left-hand side to the right-hand side, the functionality remains the same. You now also get a visual cue as to which mode the alert slider is in as you move it.

Barring these three features, the software is pretty much the same as it was on previous OnePlus phones. OnePlus has added a new font though, which you can select during initial setup, and it looks quite impressive.

The software experience was generally responsive and speedy. There weren’t any major issues that stood out.

Performance: 8/10

The Qualcomm Snapdragon 845 SoC paired with 8 GB RAM ensures that things run absolutely smooth on the OnePlus 6. The phone is capable of running anything you throw at it, be it a heavy application or high-end games, the OnePlus 6 performs beautifully. Call quality is excellent as well and the voice is clear on the earpiece speaker.

In terms of pure numbers, the Snapdragon 845 still lags behind the iPhone X in certain test scenarios such as Geekbench, but surpasses the Exynos 9810 (Samsung Galaxy S9) as well as the Kirin 970 (Huawei P20 Pro) in many tests. But like we always say, test numbers are just an indicator of performance and have no real-world bearing for most people.

The lack of stereo speaker on a flagship device in 2018 is downright surprising. Although OnePlus has retained the 3.5 mm audio jack, it hasn’t bothered to bundle any headphones – may be it wants you to invest separately in the Bullet Wireless earphones. Whatever OnePlus' excuse for not bundling earphones, I'm disappointed at the decision.

The audio output from the speakers is fine, but the mono sound is too limiting, and it gets drowns out easily if you are commuting or are in a park.

Gaming was quite good on the OnePlus 6 and it played many heavy titles such as Asphalt Xtreme, Modern Combat 5, Real Racing 3 with elan. I still have to get warmed up to PUBG and Fortnite and will add in my experiences with those games once I've spent more time with them.

Essentially, the performance is as expected from a device running the best hardware that Android world has to offer. I don't know if Gaming Mode actually gave me a performance boost though.

Camera: 8/10

The OnePlus 6 comes with a dual camera setup on the back, with the cameras arranged vertically on the central axis. There's a 16 MP primary camera with OIS up top and a 20 MP secondary camera below. Both the cameras come with an f/1.7 aperture lens. The 16 MP camera uses a Sony IMX 519 sensor which has a pixel size of 1.22 microns whereas the secondary camera houses the Sony IMX 376K sensor with a pixel size of 1 micron.

The camera interface is simple and carried forward from the previous generation. The OnePlus 6 supports a 480 fps slow motion mode at 720p. You also get a new video editor bundled with the OS. It lets you select the position where you want to slow down the action. The rear camera is capable of shooting 4K at 60fps.

Camera performance is a huge improvement over the OnePlus 5T, which wasn’t the most impressive of flagship cameras. The OnePlus 6 certainly delivers impressive-looking images. These look really good on the phone’s display. The photos come out packed with colour details and the edge sharpness is also as good as the centre sharpness. On the default 2x zoom though, the sharpness drops drastically around the edges. The HDR mode handled tricky scenes admirably. Daylight photographs aren’t an issue at all – colours are punchy, details are retained, focus is speedy and the sharpness is intact.

As the sun sets or when we are in low-lit indoor situations, the OnePlus 6’s output is hit and a miss. In scenes with humans, the details on the faces seem to take a hit. In scenes involving objects, while the details are retained, one does notices some amount of grain. The camera even struggles when there are direct light sources in the frame. For instance, in a bar scene I shot, the tungsten elements of the bulb were captured as one solid mass of yellow light. And if I do focus on that, I see the outlines of the tungsten filament and nothing else. The Google Pixel 2 does a far better job at handling low light than anything the OnePlus 6 can manage. Using the OnePlus 6 Pro mode while shooting at night gives a lot more valuable control in your hands. But on the whole, OnePlus 6 has certainly impressed with the camera performance.

The selfie camera is decent, although its portrait mode is not as great as the one seen on the Pixel 2 XL. Thankfully, unlike Honor and other Chinese brands, OnePlus does not by default overly beautify your face. The front camera also offers a flash mode where the entire display lights up.

Video shooting in daylight situations is average in the sense that you only get a great clip if the camera is steady in one position. When you pan or shoot while you are walking, you do tend to see frame drops and and an overall jerky video. This was observed more prominently on the 4k 60 fps mode and not so much with the FHD 60 fps mode. The stabilisation is decent, The same footage shot with a iPhone X returns a much smoother video. The OnePlus 6's onboard microphone captures the voice well. Video shooting indoors or in low lit situations is not good as noise mars the final output.

Battery Life: 8/10

OnePlus has decided to play it safe with the battery as it has retained the same 3,300 mAh battery capacity with the OnePlus 6. It supports Dash Charging, but as mentioned earlier, is now called fast charging because of trademark issues in the EU. Despite the change in name, it's functionally the same.

I used the OnePlus 6 as my primary device extensively, having two email accounts on sync, messaging with Slack and Telegram, shooting 50-60 photos and videos a day, streaming audio for an hour or so and watching videos for another hour. On an average I would get around 10-11 hours of battery life on the OnePlus 6 with around 3-4 hours of total screen on time.

Given my usage, the phone never lasted more than a day, but in battery saver mode, I could get the phone to last longer. This isn't much of an issue because Dash Charging juices up the OnePlus 6 in no time. It took around 75 minutes to completely charge the device and if you are in a hurry, even a 20 minute charge can give you enough talk time to last you a work day.

Our standardised Battery Life benchmark kept crashing on me so my battery life rating will have to be entirely subjective for now. On the whole, while there isn’t a major improvement in terms of battery life, fast charging is a life-saver.

Verdict and Price in India

The OnePlus 6 is a definite upgrade over the OnePlus 5T, but since it was launched just six months after the 5T, it makes little sense for 5T or even OnePlus 5 users to make the switch. This is definitely a recommended upgrade for OnePlus 3/3T users, though. The OnePlus 6 does justify its new tagline, ‘The speed you need’.

At Rs 39,999 for the 8GB RAM and 128 GB storage model, the OnePlus 6 will face some stuff competition from previous-generation flagship devices which have received a price drop, namely the Samsung Galaxy S8 and the Xiaomi Mi Mix 2, both of which are capable devices. The OnePlus 6 easily has a pricing edge over current gen flagships such as the Google Pixel 2 XL, Samsung Galaxy S9 Plus and even the Apple iPhone X, which sell for upwards of Rs 50,000. For Rs 40,000, the OnePlus 6 is a great alternative. OnePlus 6 is the only smartphone with a Snapdragon 845 chipset selling under Rs 40,000 – that itself is reason enough for many considering a flagship purchase over the next few months.

If you're fine with the 6+64 GB option, which, frankly, should be fine for most people, the Rs 34,999 makes it a compelling purchase. The Honor 10, which was also launched recently, gets flagship specs: 6 GB RAM and 128 GB storage at Rs 32,999. We are in the midst of reviewing that device as well, so if you are conflicted between this and the OnePlus 6, I’d advise waiting a little.

In terms of the overall package, cost no bar, the Samsung Galaxy S9 Plus and Huawei P20 Pro still offer the goods. If camera quality is what you're after, then the Pixel 2/2XL is the device to go for. OnePlus 6 has definitely gone ambitious with the pricing, especially with the Avengers edition even crossing the Rs 40,000 Mark – go for this limited edition device if and only if you're a hardcore Avengers and OnePlus fan. For every other user, the regular OnePlus 6 will serve well.

It looks like OnePlus has delivered a winner with the OnePlus 6. I just hope this device doesn't become redundant five months down the line with an incremental OnePlus 6T update, that would be a slap in the faces of consumers who buy the OnePlus 6. I know a lot of disgruntled OnePlus 5 users who were blindsided by the OnePlus 5T launch, but given the issues with the 5, a 5T was inevitable. I just hope that OnePlus doesn't make the same mistake twice.
