Oppo’s Find X9 Pro has a detachable telephoto lens and a gigantic battery

Oppo’s latest flagship phone, like the sleek (but hard to buy) Find N5 foldable, goes hard on the tech specifications. In fact, the Find X9 Pro’s specs read like a wishlist of what many want to see in their phones, with a huge 7,500mAh battery, a 200-megapixel telephoto camera and a bright 6.78-inch screen with tiny, almost one-millimeter bezels, all while still measuring in at 8.25mm in thickness. Oh, and an optional telephoto lens add-on that boosts camera zoom to 10x.

The Find X9 Pro will be priced at £1,099 (roughly $1,459). The biggest drawback may be that, despite the Find X9 series being Oppo’s biggest phone launch yet, it won’t be available in the US. Still, with everything that’s crammed into this phone, I had to try it out. Do I really want a thinner smartphone? Or one that lasts multiple days before it needs recharging? And man, this telephoto lens is certainly eye-catching.

Display and design

The Find X9 Pro has a 6.78-inch display, with peak outdoor brightness at 3,600 nits. On paper, that beats the iPhone 17 Pro, but most people with phones older than a year or two will notice how much brighter phones like the X9 Pro are. Another notable feature is a 1-nit minimal brightness to reduce eye strain when using the phone in the dark. Or in bed. Which we shouldn’t do, but we all do. Oppo has also included high-frequency pixel dimming to further reduce the screen’s harshness.

Like recent phones from its business cousin, OnePlus, Oppo has added a new button on this year’s Find X model. The Snap key is on the left of the device, and can be customized to launch apps like the voice recorder, translation apps and flashlight. Meanwhile, the right edge houses the Find X9’s Quick Button, which is ostensibly the camera button. Double-tapping it launches the camera app. While it’s not as elaborate as the iPhone’s Camera Control, you can swipe on the button to zoom in and out while using the camera, which is a simple, welcome addition.

Alongside Mediatek’s new Dimensity 9500 chip, the Find X9 Pro is another flagship phone with a silicon-carbon battery. With a higher energy density than graphite-based batteries, this means longer battery life without making the phone bigger or thicker. At 7,000mAh, the battery is huge. That’s far bigger than the battery found in foldables like Samsung’s Z Fold 7 (4,400 mAh) and the Pixel 9 Pro Fold (4,650 mAh). It’s even bigger than the one in the OnePlus 13 (6,000 mAh). Fortunately, the Find X9 supports suitably swift charging speeds, with support for 80W SUPERVOOC and 50W wireless charging. During my time with the phone, it would often last two days on a charge. Even after a day of heavy camera use, Google Maps and streaming video, I didn’t need to recharge the Find X9 Pro until late afternoon on the second day.

Cameras

The Find X9 Pro’s camera consists of a 50-megapixel main sensor with f/1.5 lens and optical image stabilization. There’s also a 50MP ultrawide camera and arguably the most technically impressive part: a 200MP periscope camera with an f/2.1 lens and OIS. This is further augmented with an attachable teleconverter lens — more on that later.

Oppo’s Hasselblad collaboration focuses on telephoto, though the company calls its entire camera setup the Hasselblad Master Camera System. I’m not sure it needed such a label.To make the most of the high-resolution sensor, the camera app includes a new Hi-Res mode to capture at 200MP for the telephoto lens and 50MP when using the other two camera sensors. The company warns that the mode is best used in well-lit environments, as it strips out pixel binning and other computational photography techniques that are used when there’s limited light.

But that’s not really the point: it’s all about the zoom. The telephoto has a base 3x optical zoom, which can be cropped to a 6x zoom with a 50MP image. It’s worth noting that all the cameras on the Find X9 can capture at 50MP. If the phone detects more challenging shooting conditions, it automatically drops down to 25MP or 12MP shots. In reality, I didn’t notice the resolution jump in most photos I took, although the rich foliage in some of my landscape shots showcases how much detail the camera system is able to capture.

Oppo says its computational photography know-how pushes the zoom here to 13.2x, but its algorithms can get a little aggressive and messy with faces and detail at the higher digital zoom settings. Take a look at these pictures taken across a hillside. While the foliage appears crisp and detailed, the walkers are blurry and there’s a halo effect around them. At other times, computational photography turned pedestrians into nightmarish faces.

In yet another opportunity to mention the Hasselblad collab, there’s also an XPAN shooting mode for cinematic 65:24 images. Conversely, if you’re into a disposable camera aesthetic, the Find X9 series can also trigger an aggressive double-flash to mimic ‘00s photography.

The same zoom capabilities are available in video capture, too, and the company has added a new Sound Focus mode to strip out ambient noise, which worked better than I expected it to. There are several more video recording upgrades, including full LOG recording (activated in settings) and an integrated LUT preview to check color grading in real time.

Then there’s the attachable lens. Oppo’s Hasselblad Teleconverter is a solid, premium peripheral, with a metal barrel and some heft. It extends the Find X9’s optical zoom to 10x, with an equivalent focal length of 230mm. Thanks to the high-res 200MP Telephoto camera sensor, you can punch in at up to 200x digital zoom for stills and 50x zoom for video, although the sweet spot is certainly more in the middle. The add-on teleconverter lens, while not entirely new (Vivo did it first), may be the most intriguing part.

You need to use a specific case and mounting plate to securely attach the lens to the phone, but when it’s locked in, it feels solid and very secure. It also looks, well, how it looks. Because it’s such a slender lens, it looks like something you might use for espionage. It doesn’t even look like a point-and-shoot camera. It’s… eye-catching, but also so much fun.

I’ve been testing the Find X9’s camera chops for a few weeks, and it’s been a lot of fun to zoom in with optical zoom clarity, whether at concerts, movie premieres or taking pictures of my nieces during hectic Play-Doh sessions. What’s particularly attractive is the combination of high detail and bokeh effect. With the leap in zoom, I had to ensure I was far enough away in order to use the teleconverter, or it would struggle to focus.

Oppo is pitching its new flagship as the ultimate phone for concerts and live events, and the zoom range is very impressive. Perhaps understandably, when zooming so much, there is a high risk of blurry shots. Oppo includes a special tripod mount that attaches to the lens barrel to ensure the whole thing doesn’t tip over, but it’s one step too far for me. Carrying around the teleconverter and mounting plate is already a lot. It’s also a bit of a chore to have to detach the plate when using the camera without the teleconverter. Oddly, the plate covers the other sensors, meaning that if you want a closer focal point (or want to use anything besides the telephoto sensor), it’s an additional pain point before you can take the photo.

It’s unusual that a phone’s “main” camera isn’t the star of the show, but that may be the case with the Find X9 Pro. However, it’s still technically impressive. With a new 1/1.28 sensor codeveloped with Sony, the 50MP main camera can capture triple exposures on each frame before merging them. Oppo claims that it gives images 17 stops of dynamic range. There’s also a fourth camera, a True Color camera, dedicated to precisely measuring color temperatures across all the other sensors. Combined, it’s an impressive system, but you’ll get the most out of it if you’re willing to pay for the additional teleconverter.

At £1,099 in the UK, Oppo has priced it identically to the iPhone 17 Pro, although we’re still waiting to hear pricing for the teleconverter kit. I feared foldable prices, but this seems at least competitive here in Europe.

What’s stopping Oppo from breaking into the US? Trade turbulence and competition, probably. If it can refine the experience (and maybe keep its next phone compatible with the same teleconverter), it has a good chance at charming the obsessive smartphone photographer away from their iPhones and Pixels.
