OnePlus announced the OnePlus 6 at an event in London on 16 May, and made it available for purchase a few days later on 22 May. Several details surrounding the next "flagship killer" were revealed by the company in the run up to the event but now all has been confirmed.

The question is, how does the OnePlus 6 compare to its predecessors? We have put the new device up against the OnePlus 5T and OnePlus 5 to see the differences and improvements you can expect.

  • OnePlus 6 features display notch
  • Fingerprint sensor shape has changed on OnePlus 6
  • Dual-rear camera system moves to more centralised position on OnePlus 6 
  • OnePlus 6 has water resistant build

The OnePlus 5T and the OnePlus 5 both offer aluminium builds and a similar, though not identical design. The 5T introduced an 18:9 aspect ratio display, which sees the fingerprint sensor move from the front of the device - as it is on the 5 - to the rear. 

The 5T is slightly larger than the 5, measuring 156.1 x 75 x 7.3mm compared to 154.2 x 74.1 x 7.25mm and it's a little heavier too at 162g compared to 158g. The rest of the design is largely the same though with a 3.5mm headphone jack, vertical dual-rear camera in the top left corner and a OnePlus logo in the centre. 

The OnePlus 6 shakes things up in the design department though. Like the OnePlus 5T, the front is mainly display, more so in the case of the 6 however, which has a small notch at the top and therefore slimmer bezels at the top and bottom of the display compared to its predecessor. 

The OnePlus 6 also sees the dual-rear camera move to the centre of the rear and away from the left corner, while the fingerprint sensor is more oval in shape and positioned between the camera setup and the OnePlus logo. Additionally, the 6 has an all-glass body with Corning Gorilla Glass 5 on the front and back, and it offers everyday water resistance.

In terms of measurements, the OnePlus 6 155.7 x 75.4 x 7.75mm and weighs 177g, making it the heaviest OnePlus device being compared here, but pretty much the same in terms of physical footprint. Like the OnePlus 5 and 5T, the OnePlus 6 has a headphone jack. 

Because of this change in material and the slight increase in size and weight, it does feel very different in the hand compared to the previous too. What's more, depending which colour you go for, each colour OnePlus 6 feels different to the other, despite all being glass. The glossy Mirror Black is vastly different in texture to the Midnight Black,

  • OnePlus 6 offers larger display 
  • AMOLED on all three
  • OnePlus 6 offers 19:9 aspect ratio

The OnePlus 5T features a 6.01-inch display with an 18:9 aspect ratio, while the OnePlus 5 comes with a 5.5-inch display with an 16:9 aspect ratio. Both are AMOLED screens for inky blacks and vibrant, punchy colours and both have a pixel density of 401ppi with the 5T offering a 2160 x 1080 resolution and the 5 offering 1920 x 1080. 

There is no mobile HDR support on either device, though both have Corning Gorilla Glass 5 protection, with the 5T offering 2.5D protection, which makes for a more seamless transition between the display and the edge of the device.

The OnePlus 6 comes with an increased 6.28-inch AMOLED display featuring a small notch, which means the status bar is pushed out of the main display area, which in turn means an increase in ratio to 19:9. It too is protected by Corning Gorilla Glass 5.

The resolution hasn't been increased to Quad HD for the OnePlus 6 however, with a 2280 x 1080 resolution instead. This means the OnePlus 6 offers a 401ppi too, like the OnePlus 5T and 5.

In everyday use, the new screen seems every bit as vibrant as the 5 and 5T, although to our eyes it seems the default mode is more accurate and doesn't over-saturate reds, or make whites warm, like previous screens have done. 

  • OnePlus 6: SD845, 6/8GB RAM, 64/128/256GB storage, 3300mAh
  • OnePlus 5/5T: SD835, 6/8GB RAM, 64/128GB storage, 3300mAh 
  • Dash Charge on all three

The OnePlus 5T and OnePlus 5 both run on the Qualcomm Snapdragon 835 platform, coupled with 6GB or 8GB of RAM and 64GB or 128GB of internal storage. Neither offer microSD support and both come with a 3300mAh battery capacity that supports Dash Charge.

The OnePlus 6 runs on the Qualcomm Snapdragon 845 platform with either 6GB or 8GB of RAM and 64GB, 128GB or 256GB of storage. As with other OnePlus devices, microSD support is unavailable, but like the OnePlus 5 and OnePlus 5T, there is a 3300mAh battery that supports Dash Charge.

There's no shortage of performance from any of these three phones. One of the best things about OnePlus is that its phones are fast, and can last a full day. All three do well in that respect. 

  • Dual rear cameras on all three devices
  • 16MP front camera on all three
  • OnePlus 6 adds OIS to rear and Portrait Mode to front
  • Super slow motion video capture on OnePlus 6

The OnePlus 5T and OnePlus 5 both feature dual rear cameras, though their setups are slightly different. The 5 has a 16-megapixel f/1.7 sensor and a 20-megapixel f/2.4 telephoto sensor, while the 5T has a 16-megapixel f/1.7 sensor and a 20-megapixel f/1.7 sensor, ditching the telephoto. 

Both have a 16-megapixel f/2.0 sensor on the front facing camera and both have a feature called Face Unlock on board.

The OnePlus 6 follows in the path of the OnePlus 5T, offering a 16-megapixel rear camera with f/1.7 aperture, combined with a secondary 20-megapixel f/1.7 sensor. The main sensor sees a 19 per cent larger sensor however and optical image stabilisation has been introduced for better performance in various conditions.

Like the OnePlus 5 and 5T, the OnePlus 6 has a 16-megapixel f/2.0 front sensor and the Face Unlock feature. Portrait Mode will be available on the front of the 6 as well as the rear camera soon too though, allowing users to apply a depth of field effect to selfies.

In terms of video, the OnePlus 6 offers 4K video capture in up to 60fps like the OnePlus 5 and 5T, but it also sees super slow motion mode introduced, allowing for the capture of HD video at 480fps. There is also and in-device video editor on board the latest device.

  • OxygenOS on all three 
  • New updated features on OnePlus 6  

The OnePlus 5T and OnePlus 5 both now run on the company's OxygenOS system based on Android 8.1 Oreo and they both feature OnePlus features, such as Shelf, along with the customisation options found on the OxygenOS software.

The OnePlus 6 also runs on OxygenOS, again built on top of Android Oreo, but with a few updated features including Gaming Mode, previously known as Gaming DND mode, and the option to replace the navigation bar with gestures.

These gestures include swiping up from the bottom centre of the display to go home, swiping up from the left or right of the bottom of the display to go back and swiping up from the bottom of the display and pausing to see recents.

The OnePlus 6 starts at £469 or $529 and it will be available in North America and Europe starting 22 May. The OnePlus 5T and 5 both started at £449 so there is a slight increase in price for the latest model. 

As you would expect, the OnePlus 6 does offer improvements on its predecessors though. You get an all-glass body for that extra money, along with water resistance, an improved camera, larger display and a more advanced processor.
