(Pocket-lint) - Although we've had the launch of the OnePlus 8 recently, as well as the OnePlus 7T last year, there's still a lot of interest in the previous models - the OnePlus 7 series and OnePlus 6 and 6T.
- OnePlus 6: 155.7 x 75.4 x 7.75mm, 177g
- OnePlus 6T: 157.5 x 74.8 x 8.2mm, 185g
- OnePlus 7: 157.7 x 74.8 x 8.2mm, 182g
Both the OnePlus 6 and OnePlus 6T feature a premium build quality with a metal frame and a glass front and rear, and the OnePlus 7 follows suit.
OnePlus reduced the notch on the OnePlus 6 to a tear-drop in the OnePlus 6T and it also swapped the rear fingerprint sensor for an in-display fingerprint sensor, both of which the OnePlus 7 offers. The in-display optical fingerprint sensor is said to be faster on the OnePlus 7 though, thanks to further refinement.
On the rear, the OnePlus 6, OnePlus 6T and OnePlus 7 all have a dual camera in a vertical arrangement.
Neither the OnePlus 6 or 6T have an official waterproof rating, and the OnePlus 7 doesn't change this, though OnePlus says it is water resistant. Overall, the OnePlus 7 looks very similar in terms of design to the OnePlus 6T, with a few welcomed differences to the OnePlus 6.
- OnePlus 6: 6.28-inch, Optic AMOLED, 2280 x 1080, 19:9
- OnePlus 6T: 6.41-inch, Optic AMOLED, 2340 x 1080, 19.5:9
- OnePlus 7: 6.41-inch, Optic AMOLED, 2340 x 1080, 19.5:9
The OnePlus 6, 6T and OnePlus 7 all have OLED displays. The OnePlus 7 features the same screen as the OnePlus 6T with a water-drop notch at the top and a slight increase in size and resolution over the OnePlus 6, thanks to the shifting aspect.
The OnePlus 6T and the OnePlus 7 both have a 19.5:9 aspect ratio, while the OnePlus 6 has a 19:9 aspect ratio.
Like the OnePlus 6 though, the OnePlus 6T retained a Full HD+ resolution and the OnePlus 7 does the same. They all feature a 60Hz refresh rate too.
- OnePlus 6: Dual rear (16MP + 20MP), 16MP front
- OnePlus 6T: Dual rear (16MP + 20MP), 16MP front
- OnePlus 7: Dual rear (48MP + 5MP), 16MP front
The OnePlus 6 and 6T both have a dual rear camera with a 16-megapixel main sensor and a 20-megapixel secondary sensor. Both sensors have phase detection autofocus and an aperture of f/1.7. The main sensor also has optical image stabilisation.
On the front, both the OnePlus 6 and OnePlus 6T have a 16-megapixel front camera with fixed focus and an aperture of f/2.0.
The OnePlus 7 has a dual rear camera with a 48-megapixel main sensor and a secondary 5-megapixel telephoto sensor. The main sensor is the same as the OnePlus 7 Pro with an aperture of f/1.7, phase detection autofocus and optical image stabilisation. The secondary lens has a f/2.4 aperture.
Despite improvements to the rear camera setup, the OnePlus 7's front camera is the same as the OnePlus 6T and OnePlus 6 with a 16-megapixel sensor and an aperture of f/2.0.
Hardware and software
- OnePlus 6: SD845, 6/8GB RAM, 64/128/256GB storage, 3300mAh
- OnePlus 6T: SD845, 6/8GB RAM, 128/256GB storage, 3700mAh
- OnePlus 7: SD855, 6GB RAM, 6/8GB RAM, 128/256GB storage, 3700mAh
The OnePlus 6 and 6T both run on Qualcomm Snapdragon 845, supported by either 6GB or 8GB of RAM. The OnePlus 6 comes in a 64GB storage option, along with 128GB and 256GB, while the OnePlus 6T only offers the two larger capacities.
The OnePlus 7 runs on the Qualcomm Snapdragon 855 and again, there's 6GB of RAM with 128GB or 8GB RAM with 256GB of storage, just like the OnePlus 6T.
In terms of battery, neither the OnePlus 6 or 6T offer wireless charging and the OnePlus 7 doesn't either. The 6 and 6T do both have fast charging, which the OnePlus 7 does too, though none offer the 30W Warp Charge found on the OnePlus 7 Pro, unless you're buying the McLaren Edition 6T. The OnePlus 6T and OnePlus 7 have 3700mAh batteries compared to the OnePlus 6's 3300mAh.
The OnePlus 6 and OnePlus 6T both run on Oxygen OS based on Android, as does the OnePlus 7, delivering the same user experience. The OnePlus 7 also adds dual speakers powered by Dolby Atmos.
The OnePlus 7 is very similar to the OnePlus 6T with a few hardware upgrades, including a faster processor, a main camera sensor upgrade and speaker improvements.
If you're looking to upgrade from the OnePlus 6 or below, you'll notice a difference in terms of design and performance but if you have a OnePlus 6T, you'll need to step up to the OnePlus 7 Pro for a little more excitement than the OnePlus 7 will offer. But the OnePlus 7 does stick in the position of being a "flagship killer" - it's affordable, it's powerful, but it's no longer OnePlus' flagship device.
Do check out the OnePlus 7T and 8 Series as well though.
