When OnePlus broke into the phone industry back in 2014 with the OnePlus One, it made its name with 'flagship killer' phones that undercut top-tier handsets on price, while still delivering on premium features and performance.
Since then, the company's success and expansion has meant that it now makes those very flagships it set out to kill, along with a whole set of mid-range and budget devices - the company released a total of six phones across the price spectrum in 2020, a new high.
You might spot that the 9 and 9 Pro aren't at the top of our ranking - that's because we found that they were a step back from the 8 series in a few key respects, like design and camera performance, so for the most part we'd recommend you save some money and buy one of the 2020 phones instead.
The company's cheaper handsets sit within its Nord line, starting with the superb OnePlus Nord, along with the even-more affordable Nord N10 5G and the first true budget OnePlus phone, the Nord N100. This is the only current OnePlus phone available in the UK that we haven't reviewed, so like the 9R you won't find it on this list.
The secret weapon of every OnePlus phone is the software: OxygenOS is the best Android skin out there, and the only one close to rivalling Google's own Pixel software. It means that even when the specs are equal, OnePlus phones often have an edge over other Android rivals.
Here's our rundown of the best OnePlus phones you can buy right now.
Best OnePlus phones 2021
1. OnePlus Nord - Best overall
The OnePlus Nord has proven to be a formidable smartphone in the mid-range market; delivering a premium experience typically found on devices at around twice the price, including great performance, 5G, versatile cameras, fast charging and a slick user experience.
Sure, other mid-range phones offer even more for less, but few can match the Nord's sense of style and OnePlus's superb OxygenOS user experience.
Even though this may not be the most powerful OnePlus phone, we think it's the best for most people thanks to the sheer bang for your buck it provides - there's really little reason to spend more.

2. OnePlus 8 Pro - Best for specs
The OnePlus 8 Pro is arguably the company's first full flagship, finally incorporating long-requested features like wireless charging and IP68 water resistance to make it a genuine contender with Samsung's finest.
Understandably the price has gone up accordingly, but even the base model - no slouch at 8GB RAM and 128GB storage - still represents serious value by flagship standards; meaning you will save at least some money by opting for OnePlus over most other manufacturers, and even more so now that the phone is a little older.
The 8 Pro's camera is OnePlus's best yet - it even outperformed the more recent 9 Pro in our testing - though it still lags behind rivals slightly. Throw in 5G, a great design, and the best Android skin around and the OnePlus 8 Pro is easy to recommend to anyone who can afford it.

3. OnePlus 8T - Best value flagship
The OnePlus 8T launched in autumn 2020, so it's still recent enough to compete with 2021 phones where it counts.
With a slick design and reliable camera we'd still take it over its replacement, the OnePlus 9, especially since it's considerably cheaper.
You still get a 120Hz display, 65W wired charging, and 5G support - though sadly it does omit wireless charging.

4. OnePlus 9 - The greatest of the latest
The standard OnePlus 9 is the better buy of the two 9 series phones that have launched globally, and is the one to pick if you know you want one of the company's absolute latest handsets.
You get a Snapdragon 888, 120Hz display, 65W wired charging, and for the first time in a non-Pro phone, even wireless charging too - though it's capped at 15W speeds.
You also get the firm's first Hasselblad-branded camera, though lower your expectations: while the camera gets some things right, it still can't match the best that Apple or Samsung have to offer.

5. OnePlus 8 - Still got it
Minor quirks aside, the OnePlus 8 is a fantastic flagship-class smartphone at an amazing price. You rarely get this quality level of design, features and performance at such good value.
When the biggest let down is that the main camera can do a better job of close-ups than the macro lens, you know you have an excellent device on your hands.
The main problem is that the newer, better 8T outperforms the standard 8 but has a lower asking price - though given its age you might be able to find the 8 for less, which suddenly makes it a very compelling option.

6. OnePlus 9 Pro - Best Display & Charging
The OnePlus 9 Pro was unfortunately a little bit of a let down, and feels like a step back from the phenomenal 8 Pro, and with only minor improvements over the standard 9.
The good is you get the latest Snapdragon 888 chipset, a dynamic refresh rate display (OnePlus's best yet), and the one-two punch of 65W wired charging and 50W wireless - though the latter is only that fast if you also buy the separate wireless charger. It's also IP68 rated, which the regular 9 isn't.
The bad is that the much-hyped Hasselblad camera really underwhelms. The main and ultrawide do well in good light, but struggle the rest of the time, and aggressive sharpening leaves noisy shots even in good conditions. The 9 Pro has the added advantage of a 3.3x telephoto lens, but it can't compete with zoom lens in rival flagships.
The ugly? Well, the design. It's big, blocky, and the main Morning Mist colour is the worst fingerprint magnet around.
Buy this if you absolutely need the latest specs, but most people should save money and opt for the 9 or an 8-series.

7. OnePlus Nord N10 - Best for budget
While the OnePlus Nord line is forging a path that stands out in a cluttered mid-range market, the N10 5G doesn't pack quite the same punch as the original Nord or the fierce competition from rivals such as Realme.
The highlight has to be the Oxygen OS user experience, which despite running on more modest hardware than almost any other OnePlus phone you can buy right now still feels wonderfully responsive and is unquestionably easy to use.
You also get respectable battery life paired to 30W Warp Charge 30T fast charging, expandable storage (unheard of on pretty much all other OnePlus phones) and a 90Hz high-refresh-rate display - all for less than the original Nord.

8. OnePlus 7T - Bargain buy
The OnePlus 7T is a phenomenal smartphone that still offers solid specs, featuring a large 6.55in AMOLED display with speedy 90Hz refresh rate, an upgraded triple-camera setup on the rear consisting of a wide, ultra-wide and telephoto lens and rapid 30W charging that boosts your phone by just under 50 percent in 20 minutes.
The design is eye-catching without being too in-your-face, thanks mainly to the frosted glass finish and the lightweight form factor makes it feel great in the hand.
Admittedly this is now one of the older OnePlus phones on the market, which dents its appeal, and makes it trickier to find on sale. But it's aged well, making it a great choice if you can find it at a discount.

9. OnePlus 7T Pro - Big screen at a bargain
The OnePlus 7T Pro is still a phenomenal smartphone with a gorgeous design, powerful internals and great camera performance at a pleasing price.
The 90Hz refresh rate display really makes all the difference when using this smartphone, but more recent models have outclassed it – and it’s the same with the triple-camera setup too.
Buy this if you want the larger, curved screen of the Pro models, and can find it for cheaper than the 8 Pro.
