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.
