OnePlus 8 Hands-On Review

True to form, OnePlus has announced its spring line up of smartphones, the OnePlus 8 and the OnePlus 8 Pro. Fortunately, I was sent a pair of review handsets and in this article, I’ll be going over the 8. While rumours still abound about a third lower level phone, the 8 remains the entry point into OnePlus’ range. I think it will be very popular as it shares many of the characteristics of its big brother but at a lower price. Let’s take a look…but first a word of warning. It’s really hard to write two completely different reviews for two very similar phones, so I’m going to admit right up front that some of the paragraphs are completely lifted from the review of the 8 Pro only with the detail changed for the 8. Sorry.

The 8 comes in rectangular box, bathed in the usual OnePlus red. Inside the box, the phone comes initially clothed in a slightly opaque covering. Once unwrapped, the frosted glass Glacial Green on the back becomes apparent. It’s lovely, both to look at and hold. There’s a slight matte texture to the rear glass so it’s not super slippy to hold (unlike my 6T), but you’re going need a case, and OnePlus kindly includes a transparent bumper case in the box too. In terms of colours, the Pro will offer two colour options in the UK. Onyx Black which will have 8 GB RAM and 128 GB storage, and Glacial Green with 12 GB RAM and 256 GB storage. A third colour, Interstellar Glow, will not available in the UK. I know the rear looks blue in the photos but that’s the way the back reflects light under different conditions.

Physically, the phone is 160.2 x 72.9 x 8.0 mm and weighs in at 180 g, so it’s slightly shorter and lighter than the 8 Pro, but these dimensions are very much in-line with previous generations of the phone, like the 6T. However, it’s a bigger screen for the same body size. Returning to the physical characteristics, it follows a similar layout to most OnePlus phones. USB-C 3.1 port on the bottom, volume controls on the left, power button on the right, alert slider on the right above power, cameras on the back. The SIM tray is at the bottom next to the USB port and supports two SIMS that are inserted back-to-back. A SIM ejection tool is included. There’s no audio socket and there hasn’t been for a couple of generations.

For the screen, the 8 has a lovely 90 Hz “fluid display”. It’s very fast, it’s clear and the colours look great. With a resolution of 2400 x 1080 pixels and a screen size of 6.34″/6.55″, it comes out as 402 ppi. I can’t see the dots unless I look really close. The screen has rounded edges, hence the two measurements for size. It’s an AMOLED screen with 3D Corning Gorilla Glass on top keeping it safe. Like the 8 Pro, the screen has the curved edges, but I think the curves are sharper on the 8, making it more like a traditional flat screen. There’s an in-display fingerprint sensor which is impressively fast – it’s noticeably quicker than the one on my 6T.

Under the hood, and just like the 8 Pro, there’s a Qualcomm Snapdragon 865 CPU, paired with an Adreno 650 GPU. The RAM is LPDDR4 and storage is courtesy of UFS 3.0 at either 128 GB or 256 GB. 5G is provided by the X55 chipset and WiFi 6 is supported. Performance-wise, after three runs GeekBench 5 gave average scores of 915 single-core and 3385 multi-core which comfortably beat last year’s 7T. Bizarrely, the 8’s GeekBench 5 score actually beats the 8 Pro.  I don’t know why.

Unlike the 7 and 7T, the 8 doesn’t have a teardrop camera and instead has a discreet hole-punch 16 MP camera in the top left of the screen. Round the back, the 8 has three other cameras; a 2 MP macro camera, a 16 MP ultrawide with a 116 degree field of view and a 48 MP main camera. The front camera and main camera all use Sony sensors. The cameras do stick out the back by a couple of millimetres, so a case of some kind is going to be essential to avoid scratching. The camera app itself has been improved to take advantage of the cameras automatically and will sometimes suggest that a photo would be better taken in a different mode. If you want bokeh, the portrait mode does a good job blurring the background. The macro camera’s good fun and you can play with your children to capture some of those ever-popular mini-beasts. I was really impressed by the level of magnification that was possible with the 48 MP camera and the colours are good and true to life.

The two photos below were taken from the same spot at nearly the same time. The upper one is the ultrawide and middle one is the main camera without any magnification, and the lower one is the main camera with 2x magnification.

Unlike the 8 Pro, there’s no funky colour filter camera, but there are still some effects available within the app. Here’s my shed in “black and white”. Astute readers will notice that it’s been painted (cf 8 Pro review).

Inside the phone is a 4500 mAh battery which is only 10 mAh smaller than the 8 Pro. Hmm, I think there might be a little shenanigans there to make sure that the top-end phone has the bigger battery. In what I think of as ordinary use, I got the best part of two days out of a charge, but yes, game playing is still energy expensive. For charging, OnePlus’ Warp Charge 30T delivers 30W of power and will charge the 8 from 1% to 50% in 22 minutes – I’ve actually tested this and it’s true. A Warp Charge 30 charger and cable come in the box with the 8, so there’s nothing extra to buy.

The other new feature relates to battery longevity. The perceived wisdom is that keeping lithium-ion batteries at 100% is not optimal and that overtime the capacity of the battery degrades. The 8 now has a feature (undoubtedly powered by AI) where the phone uses behaviour patterns to predict when 100% charge is needed and to charge to hit the target. For example, if you plug the 8 in at night just before going to bed, it won’t start charging until say, 0530, knowing that you usually grab the phone while having breakfast at 0700.

Based on Android 10, OxygenOS has seen a few improvements here and there but retains its closeness to stock Android that is very much part of its appeal. The most obvious of these is dynamic backgrounds which swirl and morph when the phone is turned on or you swipe between launcher pages. It’s really fun. For lovers of dark modes, OnePlus has developed a new mode theme from the ground up. I’m not generally a dark mode user, but what I did see during testing looked good: I could be a convert.

Games play really well on the 8. I tried out Call of Duty, X-Plane and Galaxy on Fire for starters and they’re all great. The 8 includes “gaming mode” and “fnatic mode” which lets you tailor the gaming experience by devoting resources and blocking notifications when you’re in the zone, as it were. It’s a super smooth experience.

The only downside I’ve discovered to the 8 is with the pre-installed screen protector. First, it’s not as well installed as it is on the 8 Pro. On the Pro, I had to look really hard to find the edges of the screen protector; it’s just about seamless and there’s no cut-out for the camera. Whereas on the 8, it’s quite obvious, particularly round the hole-punch camera. And secondly, the screen protector on the 8 seems to be a perfect dust magnet! I didn’t have this problem with the 8 Pro and it’s very annoying.

Pricing-wise…

OnePlus 8
8 GB / 128 GB – US$699 / GB£599
12 GB / 256 GB – US$799 / GB£699
The OnePlus 8 series will be available SIM-free from OnePlus.com, John Lewis and Amazon from 0900 on 21 April, with all John Lewis purchases also coming with Bullets Wireless 2 headphones while stock lasts.

Overall, this is a seriously good phone at a good price and very much continues the progression of the standard OnePlus phones. It’s a premium-feeling phone, it looks fabulous, there’s no skimping on the performance and everything else like the screen and the cameras are within spitting distance of the 8 Pro. You get 5G, WiFi 6, fast charging and OxygenOS. Frankly, if it was my money and the choice was between an 8 at £599 and an 8 Pro at £799, I think I’d buy the 8 and keep the £200 change.

Thanks to OnePlus for supplying the 8 for review.
