Oppo Find X8 Ultra review: The best Ultra phone released in 2025!

Oppo Find X8 Ultra Intro

Oppo has just announced its latest top flagship, the Oppo Find X8 Ultra, and it’s the perfect example of why looks can be deceiving. 

On the outside, it appears to be a fairly inconspicuous device with a friendly and elevated design that doesn’t really try to capture your attention with any flashy features. Only the densely populated camera assembly at the back hints that something exceptional is going on here. 

On the inside, however, the Oppo Find X8 Ultra is a wolf in sheep’s clothing. Aside from the remarkable Snapdragon 8 Elite chip, the insane 16GB RAM and a very promising penta-camera, we also get a sizable 6,100mAh battery in a body that’s below 9 mm in thickness and superfast 100W wired charging support. Superphone, indeed.

Oppo Find X8 Ultra Specs

Fully deserving of the “Ultra” name

Here’s a summarized table with the essential Oppo Find X8 Ultra specs:

The Oppo Find X8 Ultra relies on a very understated, safe design language. Nothing too fancy or unique, just a flat aluminum design with a frosted glass back panel that is simple, but well-made. The phone’s build is extremely solid and it feels very premium.

You can map various functions and shortcuts, like switching the sound modes, opening the camera, enabling the flashlight, taking a screenshot, or adding a memory to the on-board Breeno AI assistant. We don’t mind Oppo copying the idea of the Action button, but it also copied the user interface and that just feels unnecessary.

Another interesting hardware feature here is the side-positioned capacitive Camera Control Quick button, which is used to interact with the camera: a double-press opens it, clicking takes a picture or starts recording a video, while swiping up and down lets you zoom in and out. One difference with the Apple solution is that you can actually press down the iPhone’s Camera Control button, while this is just a capacitive area that you tap on. Oppo already did something similar earlier with the Find X8 Pro, but this version has better finger movement recognition.

However, the most imposing design feature here is probably the large camera housing at the rear, which Oppo calls the Cosmos Ring. It’s a very smart-looking camera island, but somewhat impedes the ergonomics of the phone as your fingers are always naturally forced beneath the Cosmos ring, and that hurts the overall grip. I had a similar complaint about the Xiaomi 15 Ultra, and while Oppo’s iteration is slightly slimmer, it’s still a little annoying and worth mentioning. 

The Oppo Find X8 Ultra is available in Matte Black, Pure White, and Shell Pink colors, which is a fairly decent and varied selection of hues. All color versions feature silky smooth matte finishes, so there’s no major difference aside from the color itself. 

The phone is very well protected against the elements, boasting both the IP68 and IP69 water- and dust-resistance standards. While IP68 is now standard on flagships and is slowly trickling down towards mid-range and entry-level phones, IP69 is a bit more exclusive standard that protects the device from high-pressure water pulses from different angles. 

The display is slightly colder than most other flagships in the default screen color mode, but you can manually make the screen warmer or colder, as well as enable D65 color temperature or outright switch to vivid mode. There’s an adaptive tone setting, which functions a lot like Apple’s True Tone and adjusts the colors based on the ambience. 

Display Measurements:

Biometrics are sorted by an ultrasonic fingerprint scanner embedded into the display, which is superfast and very accurate. You can also enroll your face for a picture-based unlock, but that’s not a very secure practice. 

The Oppo Find X8 Ultra performs extremely well in the custom PhoneArena Camera Score test, achieving a top score of 157 points, nearly tied with the Xiaomi 15 Ultra and the Galaxy S25 Ultra for the top spot! That’s largely thanks to a very high result in our video test, whereas the still photography test is a little lower at 160 points versus 165 achieved by the Samsung and Xiaomi contenders.

And exploring the camera specs surely explains why the Oppo Find X8 Ultra performs so well in the camera department. There are five cameras at the rear, but one of those is a sensor, so you essentially get four actual cameras. As usual with Oppo, the cameras are tuned by Hasselblad, a long-time Oppo partner in the camera department. 

The main camera uses a massive 1-inch 50MP Sony LYT900 camera sensor, the same one that the Xiaomi 15 Ultra uses as well. The aperture here is slightly narrower at F1.8 versus F1.63 on the Xiaomi. The camera also notably uses an 8-element lens with high-refractive glass, which aims to minimize chromatic aberration. Thanks to in-sensor cropping, you also get lossless 2X optical zoom with the main camera as well. 

There are 3X and 6X zoom cameras here, but interestingly, the shorter one isn’t a regular telephoto but a proper periscope. With a 70mm equivalent, it’s best suited for portraits (Hasselblad portrait is supported here) and telemacro shooting thanks to its minimum focusing distance of just 10cm. This is the proper way to shoot macro photography: not with a low-res dedicated camera or by cropping the ultrawide, but with a high-quality periscope lens that lets you capture tight macro shots with extremely shallow depth-of-field.

The longer periscope uses a Sony LYT-600 sensor and delivers a 6X optical zoom, or a 135mm equivalent. Thanks to Oppo’s hybrid zoom algorithms, you can zoom to 120X on the Oppo Find X8 Ultra. The F2.0 ultrawide also uses a 50MP sensor, but it’s a Samsung JN5 one and offers a standard 120-degree field-of-view, consistent with most other flagships.  

Oppo Find X8 Ultra features the company’s latest HyperTone Image Engine for computational photography, which takes care of the image-processing and color science of the camera. AI-assisted tone-mapping and improved dynamic range are also sorted by the HyperTone Image Engine. 

But probably the most useful feature here is the camera button, which lets you easily launch the camera from just about anywhere. It lets you quickly snap a photo or start recording a video in an emergency, which is super useful. Just like on the Oppo Find X8 Pro, you can’t use the camera button to zoom in when the phone is in portrait mode, only when it’s in landscape. A minor annoyance if we’ve seen one. 

Main Camera

The image quality with the main camera is superb. You get excellent dynamic range, with the phone having no problems capturing a superb picture in even the most extreme conditions. There’s that natural detail with just the right amount of sharpness and pretty much no oversharpening present, making for some extremely true-to-life photos. In low-light conditions, the phone captures well-exposed photos, and we love the fact that it doesn’t try to turn the night into day by overexposing them. 

Zoom Quality

The zoom quality with both the native 3X and 6X cameras gives us a very natural detail with no oversharpening. The dynamic range is good, but not exceptional here. While the Xiaomi 15 Ultra and the Galaxy S25 Ultra perform slightly better in the short zoom range, the Oppo Find X8 Ultra performs very well in the longer zoom range. However, the more you zoom past 10X, the more extreme the overprocessing becomes.

Ultrawide

The ultrawide camera is decent, but scenes tend to get under-exposed and slightly colder than real life. Other than that, the ultrawide camera here is just as usable as on other flagship phones. 

Selfies

Selfies are superb here, with excellent sharpness, dynamic range, and colors that both pop out and stay true-to-life. Lovely!

Video Quality

The Oppo Find X8 Ultra can take 4K60fps videos, and while the official press release mentions it’s also capable of taking 4K120fps videos, our unit lacked the option. 

Other than that, videos taken with this phone are splendid, especially when it comes to detail. There’s superb sharpness even at 30X zoom! The dynamic range and the colors are also great. The selfie camera is decent, but the rear one definitely takes the cake when it comes to videos. 

Unsurprisingly for a phone that carries the “Ultra” suffix in its name, the latest Oppo flagship comes along with the Qualcomm Snapdragon 8 Elite chipset, one of the most powerful mobile chips at the moment. 

It’s a 3nm chipset with eight cores, but it has a slightly lower max clock speed in comparison with the Snapdragon 8 Elite for Galaxy, which ticks inside the Galaxy S25 Ultra. That isn’t noticeable in everyday life.

There’s also a RAM expansion feature, a signature for many Chinese phones, which allocates some internal storage to be used as memory. Here, you can expand the memory by up to 12GB, for a total of 28GB. Thanks to this, apps are kept preloaded in the background for longer, so you don’t get as many app reloads.

In the Geekbench 6 multi-core test, the Oppo performs just as good as its rivals, with only the Galaxy S25 Ultra performing slightly better here. 

GPU Performance

When it comes to graphics performance, the Oppo Find X8 Ultra is exceptional. It beats all of its rivals in the 3DMark benchmark, where it achieves the top “high” result, which reflects the initial burst of performance. The “low” result, on the other hand, demonstrates how the phone performs when it has throttled a bit. 

Oppo Find X8 Ultra Software

Now, the Oppo Find X8 Ultra isn’t scheduled to arrive on the global market and will most certainly remain China-exclusive, which is the reason the interface is preloaded with many apps specific to the Chinese smartphone market. Even if you set the default language to English, you’d often be stopped in your tracks by prompts, alerts, and options worded in Mandarin. That’s completely natural, and in stark contrast with the global version of the software which is pruned. 

In terms of AI, the phone has a lot to offer… but to Chinese users. For example, AI Search only works with Simplified Chinese, while AI Writer says it will only work in a handful of Chinese apps. 

Even the default AI assistant on board, Breeno, doesn’t seem to speak an ounce of English. While you can install and use Gemini, there doesn’t seem to be an option to invoke Google’s assistant with the power button, or at least I didn’t find such an option. 

Overall, it’s a phone that’s geared towards its domestic market, and that’s perfectly fine. 

In terms of software support, we expect that Oppo will deliver five major Android updates and six years of security support to this one, which isn’t bad at all. 

We love the onslaught of silicon-carbon batteries, as they finally offer some much-needed movement in the top ranks when it comes to battery life.

And indeed, the Oppo Find X8 Ultra performs admirably in our battery life tests, almost averaging nine hours, which is an excellent result! 

The phone fares particularly well in our custom web browsing test, which aims to replicate a regular web browsing experience with the screen set to 200 nits, achieving a result of nearly 24 hours. The Oppo Find X8 Ultra also beats its rivals in our custom video test. It also fares well in our 3D gaming test with a result of nearly 13 hours. 

Overall, great job, Oppo!

And charging is even more impressive: drawing inspiration from multiple previous Oppo and OnePlus phones, the Find X8 Ultra boasts superfast 100W wired charging, which fully charges the phone in just 32 minutes. That’s definitely the fastest charging phone with a 6,000mAh+ battery we’ve seen. 

The Oppo Find X8 Ultra also boasts 50W wireless charging, though the latter requires the company’s bespoke AIRVOOC charger. There’s reverse wireless charging, too. 

Audio sounds great on the phone’s dual stereo speakers. It’s loud without distortion even at high volume, and the bass is surprisingly strong. The sound stage is fairly wide, and both mid and high frequencies sound very clear. 

The haptics are also great. Oppo has always put excellent haptic motors in its flagship phones, and the Find X8 Ultra isn’t different. Haptics are accurate, strong, and precise, in the same ballpark as a Galaxy flagship or an iPhone. 

The Oppo Find X8 Ultra is a brilliant Android device that does many things right. 

It has a friendly and understated design language that shines with its simplicity, while also offering some unique hardware features that set it apart. Battery life is absolutely incredible — the phone just goes, and goes, and goes… The performance is snappy, too, and animations look buttery smooth. Typically for Oppo, the charging is exceptional too. Finally, the camera is feature-rich and delivers awesome image and video quality.

Should you get this one? Unlike the Oppo Find X8 Pro that I reviewed several months ago, this one isn’t really aimed at the global power-user, so you can only buy it in China. And while most people won’t be able to buy it, this phone shows mainstream brands like Apple and Samsung that they can push harder with their Pro Max and Ultra models.
