Bottom Line

The OnePlus 9 Pro holds its own against other flagships with a spectacular ultra-wide camera, smooth performance, and impressively fast wireless charging.

US Street Price$969.99

The OnePlus 9 Pro smartphone (starting at $969.99) delivers a streamlined flagship experience to T-Mobile and Verizon subscribers, finally catching up to its competitors. The phone itself is light in the hand, and the user experience is weightless as well. The cameras take knockout photos in pretty much all conditions and the integrated fast charging is the best we've seen. The Galaxy S21 Ultra scores a bit better in our battery and wireless radio testing, it works with Samsung's excellent S Pen stylus, and its camera offers killer optical zoom, so it just edges out the 9 Pro to be our Editors' Choice among flagship smartphones. Still, the OnePlus 9 Pro is outstanding. If you want a top-notch, loaded phone that makes your heart sing, you're now spoiled for choice.

The OnePlus Promise Is Finally Realized

OnePlus was once a company that made a single great phone at a time. Now it has a full line of phones at T-Mobile (and providers such as Google Fi, Metro, and Mint Mobile that use T-Mobile's networks): the $969.99 OnePlus 9 Pro, the $729.99 OnePlus 9, the $299.99 OnePlus Nord N10, and the $179.99 OnePlus Nord N100. They all share the OnePlus philosophy, which means speedy, elegant software and a streamlined physical design. Cameras have always been the one place OnePlus tended to fall behind Samsung and Apple, so OnePlus made a deal with Hasselblad for color tuning and bought a new sensor from Sony. As a result, the 9 Pro's camera is mostly on par with the latest from Samsung, only slightly short only on optical zoom.

The OnePlus 9 offers similar overall performance to the 9 Pro but steps down a bit on screen, camera, and radio quality, and it doesn't integrate super-fast wireless charging. If you don't mind those downgrades, you can save $240 and get an even smaller and lighter phone. See our review of the OnePlus 9 for all the details.

Light, Sleek Design

The 9 Pro's base model has 8GB of RAM and 128GB of storage. The 12GB/256GB model costs an additional $100. There is no memory card slot. The phone is perfectly sized, measuring 6.42 by 2.89 by 0.34 inches (HWD) and weighing 6.9 ounces. That's a little wider than the 2.8 inches we use as the cutoff width measurement for small phones, but it's noticeably smaller and lighter than the Galaxy S21 Ultra, and narrower than the OnePlus 8 Pro. Of the three, the 9 Pro is the easiest to use with a single hand.

                The OnePlus 9 Pro comes in green or silver.

The design, very in tune with OnePlus's "burdenless design" philosophy, is slim and elegant. The phone's body is rounded, with the traditional OnePlus mute switch on the left side and the Hasselblad-branded camera module on the back. The camera doesn’t stick out nearly as much as recent Samsung camera bumps do (because it doesn't have a giant periscopic zoom lens in it). The front-facing camera is a hole-punch on the upper left corner, just like on the 8 Pro.

The phone has an IP68 rating for water and dust resistance, and comes in two colors. If you're not going to put your phone in a case, we like the matte pine green better than the mirrored silver "morning mist" glass back, which has a greasy-fingerprint problem. Our review unit came with a black carbon-fiber case that made that issue moot. (There's a third, black phone, but OnePlus tells us it won't be sold in the US.)

The mirrored back of the silver case is a fingerprint magnet.

Unlike the Galaxy S21 Ultra and recent iPhones, your OnePlus phone comes with a cable and a 65W charger. Luxury! There's a reason: OnePlus uses proprietary USB-C chargers. Though the phone will charge from any USB-C source, it'll only achieve its highest charging speeds with the included charger.

There's no headphone jack, and no headphone adapter included in the box. At this writing, OnePlus's own (very good) USB-C headphones are out of stock. You'll have to go with a third-party adapter or third-party wireless USB-C earphones. You can also go wireless. OnePlus Buds and even less expensive Buds Z both offer customizable tap functions that only work with OnePlus phones. If you're looking at other wireless earbuds, try to find a pair that supports Qualcomm's aptX HD codec, since it's the highest-resolution codec available on the 9 series.

As for the onboard speakers, the audio quality is excellent. Dual stereo speakers deliver audio with a peak volume of 98dB and a surprising bit of mid-bass. For voice calls, which have a maximum volume of 81dB, the phone supports the best voice codec currently available, HD voice with EVS.

A Bright, Yet Battery-Saving Display

The bright and beautiful 6.7-inch, 525ppi, 3,216-by-1,440-pixel screen can be dialed back to 1080p in the phone's settings if you want to conserve battery life. The display uses a relatively new technology called low-temperature polycrystalline oxide (LTPO) that reduces power consumption and gives phone manufacturers more control over refresh rates. It was previously seen in the Samsung Galaxy Note 20 Ultra and the Galaxy S21 series. It's worth noting that only the 9 Pro, not the 9, offers this screen technology.

The LTPO display helps save power.

This is a top-of-the-line OLED display with a bonus: It's very visible in direct sunlight. A screen protector is preinstalled; we didn't remove it from our test unit. According to DisplayMate Labs tests, the 9 Pro's display set to Auto Brightness mode beats the 8 Pro, the Galaxy S20 series, and the latest iPhones in ambient light, but not the Galaxy Note 20 Ultra. The 9 Pro also improves the maximum color gamut in its vivid display mode, which helps it maintain color saturation in outdoor lighting.

Ultra-Super-Mega-Fast Charging

The pair of batteries in the 9 Pro total 4,500mAh. That's short of the Galaxy S21 Ultra's 5,000mAh, but OnePlus has a range of software tricks up its sleeve to keep the phone charged—so many that we're not even sure all of them came into use during our testing.

On our standard battery test, running a YouTube video over Wi-Fi at full screen brightness, the phone lasted for 8 hours, 50 minutes in WQHD resolution and 9 hours, 40 minutes in HD. Display brightness matters a lot to battery life: Take the brightness down to 75% and those numbers jump to 12 hours, 40 minutes on WQHD and 13 hours on HD. Technically, that's shorter than either the Galaxy S21 Ultra, which managed 11 hours 20 minutes at 100% brightness, or the Galaxy S20 FE, at 12 hours 30 minutes at 100% brightness, though it's still pretty credible.

But there's more to this battery than meets the eye. To start with, the display slows down to 1Hz when you're looking at static content, such as an email you're mulling over or a page of an e-book. That can be a huge power saver. OnePlus also has a reputation for losing less power to background processes than Samsung does. If you use 75% screen brightness most of the time, you'll probably get more than a day of battery life from one charge.

The Warp Charge 65T charger can completely recharge the 9 Pro in about 30 minutes.

The 9 Pro also has by far the fastest charging speeds of any phone we've ever tested. It comes with a Warp Charge 65T USB-C charger, which charges the 9 or the 9 Pro from 0% to 20% in six minutes and to 100% in just 36 minutes. That's twice as fast as any recent Samsung phone charges. If you use a third-party charger, the phone will charge at up to 18 watts, with correspondingly longer charge times.

The real breakthrough is in OnePlus's new Warp Charge 50 wireless charger, a $69.99 accessory cradle that plugs into your existing Warp Charge 65 adapter to provide 50-watt wireless charging for the 9 Pro, or 15-watt Qi charging for any other device. In testing with the Warp Charge 50, the 9 Pro went to 29% in 11 minutes and 100% in 46 minutes. Other phones, including the 9, take between 90 minutes and two hours to wirelessly charge completely.
