Verdict on the Oppo Find X8 Ultra
The Find X8 Ultra is one of the best smartphones of 2025, especially with regard to its cameras' excellent allround qualities. A look at the comparison photos taken on the iPhone 16 Pro shows just how well the Oppo flagship performs—regardless of the native focal length. But even aside from its Hasselblad cameras, the Find X8 Pro's big brother boasts loads of highlights, such as impressive runtimes and high performance with comparatively low throttling.
Oppo hasn't suffered any true blunders with its 2025 flagship; if anything, we see some room for improvement when it comes to the topics of sustainability and updates. Its availability in Europe, where this test was carried out, can also be noted as a negative as a result of a missing global model of the Find X8 Ultra.
Pros
Cons
Price and availability
So far, the Find X8 Ultra has only been presented for the Chinese market. In China, prices start from 6,499 Yuan (around $900).
You can import the phone from Trading Shenzhen for approximately $1,000. It's unlikely that the Ultra model will see a global release.

After the release of the Find X8 Pro, Oppo has now presented the Ultra model of its flagship phone, which is said to be better in almost every respect. Different from the Pro version, which features a MediaTek SoC, this model uses a chipset from Qualcomm, namely the Snapdragon 8 Elite.
The highlight of its features is its huge camera module on the back, which in part consists of even larger sensors than Find X8 Pro's camera lineup. It's in this context that Oppo has introduced its new image editing system called Lumo.
Specifications of the Oppo Find X8 Ultra
Case - The waterproof high-end phone
The Oppo Find X8 Ultra has an eye-catching glass case: With a thickness of only 8.78 millimeters and a weight of just 226 grams, it features quite a nifty build despite its 6,100 mAh battery. However, the flagship phone is by no means small with its 6.82-inch screen. The slim bezels around the OLED display which, according to Oppo, measure 1.4 millimeters wide, ensure a high screen-to-body ratio of over 90 percent, resulting in a modern look.
The Find X8 Ultra's haptics are great and its matte frame made from an aluminum alloy not only gives the flagship smartphone stability, but also a nice premium feel. Noteworthy is the button on the left side of its case, which users can freely assign, as well as a capacitive button on the right side that opens the camera app.
The Oppo smartphone's build quality is great and the same can be said for its durability. The Find X8 Ultra has received a five-star certification for drop and fall resistance from the Swiss company SGS, supported by IP68 and IP69 certifications, which protect the case against water and dust. Instead of Gorilla Glass, Oppo uses an unspecified "Crystal Shield" glass.
Connectivity - The Android phone with USB 3.2
In addition to Bluetooth 5.4, NFC, an IR blaster and Miracast, the Find X8 Ultra features a fast USB-3.2 connection (Gen 1) that supports wired image output. USB OTG is also on board, letting users connect peripheral devices to the Oppo phone. It doesn't have an UWB chip, on the other hand.
Software - The high-end smartphone with Android 15
The Find X8 Ultra is set to receive Android operating system upgrades for four years and security updates for five years. This isn't bad, but it's not really good either. Other flagship phones, such as the Galaxy S25 Ultra or Pixel 9 Pro, for example, will receive new Android versions for seven years. Security patches for the Find X8 Ultra will also only be rolled out quarterly; during our test, these were dated April 1, 2025.
Oppo's smartphone comes delivered with Android 15 including the company's own ColorOS 15. Even though the Find X8 Ultra will never officially come to Europe, it still supports a wide range of system languages. There is no PlayStore pre-installed ex works, but it can be easily installed later.
Sustainability
No information on sustainability is available for the Oppo flagship—the manufacturer still has some catching up to do in this case.
Its packaging is free of plastic and has been printed with inks based on soybean oil.
Communication and GNSS - The Oppo Find X8 Ultra with 5G
The Find X8 Ultra's frequency coverage promises no restrictions in Europe. However, the Oppo phone only supports 18 LTE bands. Satellite communication via Tiantong satellites is only available for the Chinese market.
For Wi-Fi connections, the Find X8 Ultra offers the best of the best in the shape of the current Wi-Fi 7 standard, especially since our Chinese version also uses the 6 GHz channel to establish a connection.
However, we only noted average transmission rates of around 600 MBit/s using our Asus AXE11000 reference router. The flagship was significantly faster when receiving.

The Find X8 Ultra offers fast and precise satellite location services.
During our practical tests, the Oppo phone's results were quite accurate and in some cases even more accurate than our Garmin smartwatch.
Telephone functions and call quality - The Oppo phone with dual-SIM support
The Oppo smartphone offers full dual-SIM functionality via the 5G network, with two slots for nano SIM cards. Using the Chinese version of Color OS, we didn't have the option to integrate an eSIM in our country.
Even so, users from Europe can also make use of WiFi calling and VoLTE. The phone's call quality via the earpiece was good overall during our test, but our conversation partners sometimes sounded a little muffled. The three microphones recorded our voice clearly.
Cameras - The flagship smartphone with Sony sensors
On paper, the camera setup of the Find X8 Ultra, including its Hasselblad branding, appears to be no different from the Pro model. However, with the exception of its 15 mm lens, the sensors are all different and significantly larger than on the Find X8 Pro or the iPhone 16 Pro.
A 32-MPix lens is used on the front, which can record 4K videos at 60 frames per second. Selfies taken on the Find X8 Ultra appear rich in detail and show good sharpness levels.
The smartphone's 23 mm main camera with a huge 1-inch sensor from Sony (LYT-900) delivers very good photo quality. Thanks to the XXL sensor, backgrounds are usually blurred even when using the regular photo mode. The X8 Find Ultra delivers appealing sharpness and a high dynamic range.
Where the contours of photos taken with an iPhone 16 Pro are already blurred by a pronounced soft focus in direct comparison, such as the church tower or roof shingles in the second test photo, the Oppo flagship delivers plenty of detail. Similar to the Vivo X200 Pro, the Find X8 Ultra has some problems with lens flare and backlit shots.
The Oppo phone also performs really well in low-light scenarios.
The two telephoto lenses with OIS and 3x and 6x lossless zoom also have very large 1/1.56 and 1/1.95-inch sensors for a periscope effect. In conjunction with the digital "AI zoom", the Find X8 Ultra achieves a magnification of up to 120x. The Find X8 Ultra can take really good photos up to 10x, after which it looks somewhat artificial.
Its ultra-wide-angle lens doesn't stand out but is still very competitive. The phone's setup is rounded off by a special spectral sensor, which is designed to ensure accurate colors even under difficult conditions. With Master mode selected, users can make use of the full resolution of the sensors in RAW and JPEG.
You can record video in UHD quality at 120 fps—even in HDR. However, it isn't possible to change lenses at 120 frames per second, as the ultra-wide-angle lens only supports 4K30.
The phone's stabilization and adjustment of its colours and white balance are generally a success.

Accessories and warranty - The Android phone with a power supply
The box contains a modular 100-watt fast-charging power supply, a protective cover, a data/charging cable (USB-A to USB-C), a SIM pin and a quick start guide. A film comes pre-installed on its screen.
Our imported device comes with a 12-month warranty. In the event of a warranty claim, Trading Shenzhen offers the option of sending the smartphone to a German shipping address.
Input devices and operation - The Oppo phone with an ultrasonic sensor
The Find X8 Ultra uses an ultrasonic sensor to recognize the user's fingerprint. This is not only more secure than an optical counterpart, as it detects depth and skin structure, but it's also less susceptible to scratches or moisture on your finger. During everyday use, the sensor in the Oppo phone works very quickly and reliably.
If you want to use facial data to unlock the screen, you can do so via the front-facing camera. However, facial biometric identification isn't as secure as it uses a 2D process.
Users benefit from a high screen sampling rate of up to 240 Hz and a refresh rate of 120 Hz. Oppo has installed a great vibration motor, which provides pleasant haptic feedback during everyday use.
Display - The Oppo Find X8 Ultra with LTPO
With a resolution of 3,168 x 1,440 pixels, content is displayed sharply on the phone's 6.82-inch AMOLED panel. Its pixel density is super high at 510 PPI.
Measuring in at 4,202 cd/m², the device's brightness we noted during the more realistic APL18 test was extremely good. Still, OLEDs usually shine a little brighter when playing HDR content. But even so, nothing stands in the way of the phone displaying videos with a wide dynamic and contrast range.
The Find X8 Ultra uses classic pulse width modulation to control its brightness, which, according to the manufacturer, works using PWM dimming and a high frequency of 2,160 Hz. We measured PWM flickering at very low brightness levels, but with a frequency adapted to the device's frame rate.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 121 Hz Amplitude: 40 % |  | |
The display backlight flickers at 121 Hz (worst case, e.g., utilizing PWM) . The frequency of 121 Hz is very low, so the flickering may cause eyestrain and headaches after extended use. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8350 (minimum: 5 - maximum: 343500) Hz was measured. | |||
Measurement series with fixed zoom level and different brightness settings (The amplitude curve at minimum brightness looks flat, but this is due to the scaling. The info box shows the enlarged version of the amplitude at minimum brightness).
In addition to selecting various color profiles, users can adjust the Find X8 Ultra's white balance.
We examined its color calibration using the Calman analysis software and a photo spectrometer. With the "Pro" profile selected, we noted the smallest deviations from the reference colors as well as very high color fidelity.

We noted no problems when using the Oppo phone outdoors and content can be read from its screen even in direct sunlight. Its viewing-angle stability is also very good.
Performance - The high-end smartphone with a Qualcomm SoC
The Find X8 Ultra was mostly on par with the competition with the Snapdragon 8 Elite, but the Oppo phone sometimes performed worse during the AI test.
Still, the Adreno 830 in the Find X8 Ultra performed particularly well during the GFXBench test.
