Design & Build Quality

At first glance, the Oppo Find X9 Pro looks every bit a modern flagship. The front is dominated by a large, curved-edge display with ultra-thin bezels, giving it a very high screen-to-body ratio. The punch-hole front camera is tucked neatly at the top, and the aluminium frame feels solid without being too sharp or slippery.

The back is where Oppo Find X9 Pro design language really shows: a prominent squared camera island houses the triple main sensors and Hasselblad branding. The finish options such as Silk White and Titanium Charcoal offer a matte, premium look that resists fingerprints better than glossy glass backs.

Durability is another highlight. You get:

Corning Gorilla Glass Victus 2 Oppo Find X9 Pro protection on the front

IP66, IP68 and IP69 ratings, which cover dust resistance, immersion in water and even high-pressure water jets

An ultrasonic in-display fingerprint sensor, which generally works better with wet or slightly dirty fingers than optical readers

Considering the huge battery inside, the phone’s thickness and weight are quite reasonable. It’s not a featherweight, but it feels well-balanced in the hand for a big-screen flagship.

Display: Bright, Smooth and Colour-Rich

FHD+ 2772 × 1272 resolution with high pixel density for sharp text and images

Videos and games look vibrant and fluid

Text remains crisp and easy to read

Overall, the display comfortably sits in the top tier of 2025 Android flagships.

Performance: Dimensity 9500 Power

Under the hood, the Oppo Find X9 Pro is powered by the MediaTek Dimensity 9500, paired with 16GB of LPDDR5X RAM and fast UFS 4.1 storage. This combo is built for serious workload:

Apps open quickly and switching between multiple apps remains smooth

Software: ColorOS 16 on Android 16

The Oppo Find X9 Pro runs ColorOS 16, based on Android 16. ColorOS has matured into a feature-rich, polished interface with:

Scene detection and automatic tuning in the camera app

Battery and performance management suggestions based on usage

If you like having lots of extra tools and settings rather than a very minimal, “stock” look, ColorOS gives you a lot to explore.

Camera System: Hasselblad Collaboration in Your Pocket

Rear Cameras

The Oppo Find X9 Pro camera system is one of the major reasons to buy the Oppo Find X9 Pro. Oppo has teamed up with Hasselblad to tune colours, portrait rendering and overall image processing, and the hardware itself is extremely capable:

The 50MP main camera uses a large 1/1.28" sensor with a bright f/1.5 lens and optical image stabilisation. It captures detailed, clean images in daylight and holds up well in low light, especially with night mode enabled.

The star of the show is the 200MP periscope telephoto sensor. With a relatively large 1/1.56" size and OIS, it can deliver crisp 3x optical zoom and impressive detail even when pushed further with digital zoom. It also supports tele-macro, allowing you to take close-up shots from a distance with a unique perspective.

The 50MP ultra-wide camera offers a 120° field of view and autofocus, so it can handle everything from sweeping landscapes to close-up wide shots with minimal distortion.

The modest 2MP mono / True Colour helper sensor, paired with a spectral colour sensor system, helps the phone measure light and colour more accurately, improving skin tones and overall colour consistency.

In real-world photography, you can expect:

Natural-looking colours rather than oversaturated extremes

Strong Oppo Find X9 Pro portrait shots with realistic background blur

Impressive detail in zoomed-in images at moderate zoom levels

Good control over highlights and shadows in high-contrast scenes

Oppo even offers an optional Hasselblad Teleconverter Kit (sold separately in some regions), which physically extends the camera’s optical reach for photography enthusiasts.

Front Camera

On the front, Oppo Find X9 Pro the 50MP selfie camera with autofocus can shoot detailed photos and supports 4K video. This makes the phone a strong option for vloggers and content creators who want high-quality front-facing footage without needing a separate camera.

Video Capabilities

The Oppo Find X9 Pro supports a range of video modes:

Up to 4K at high frame rates on the rear cameras

Slow-motion in both 4K and 1080p

HDR and log-style profiles in certain modes, useful for those who like to colour-grade video

Dual-view video, time-lapse and long-exposure video modes

Combined with the large sensors and stabilisation, you get stable, sharp clips suitable for social media, short films or vlogs.

Battery Life & Charging: 7,500mAh Monster

Perhaps Oppo Find X9 Pro the most striking spec on this phone is the 7,500mAh battery. That’s significantly larger than the usual 4,500–5,000mAh capacity you see in most flagships.

In practical terms:

Light and moderate users can realistically expect two days of use between charges

Heavy users (gaming, camera, 5G data, GPS) can still comfortably get through a full, intense day without needing a mid-day top-up

Charging is equally serious:

80W wired fast charging Oppo Find X9 Pro can take the phone from low to a strong charge in well under an hour in many real-world scenarios

50W wireless charging means you can still top up quickly even without plugging in, provided you have a compatible wireless charger

For people who travel a lot, work long hours on the phone, or just don’t want to worry about battery anxiety, this is a huge advantage.

Connectivity & Extra Features

The Oppo Find X9 Pro covers all modern connectivity bases:

Wi-Fi 7 for high-speed home and office networks

Bluetooth 6.0 with support for high-quality audio codecs like LDAC, aptX HD and LHDC

NFC for contactless payments and quick pairing

USB-C with USB 3.2 Gen 1 speeds for fast file transfers and better accessory support

Dual-SIM and eSIM support for flexible network options

Who Should Buy the Oppo Find X9 Pro?

The Oppo Find X9 Pro makes the most sense if you:

Want serious battery life and are tired of charging your phone every evening

Play games or consume a lot of media and appreciate a bright, smooth display

Need a phone that can withstand daily abuse, with strong water and dust resistance
