Oppo Find X9 Ultra teardown video reveals internal design
The Oppo Find X9 Ultra was unveiled last week, and now a full teardown of the device is already available thanks to our colleagues at the YouTube channel WekiHome.
As always, they performed a detailed teardown of the device, in which the smartphone is not only quickly disassembled, but the function of each component is also described in detail.
The video embedded above is in Chinese, but the automatically translated YouTube subtitles work perfectly.
Oppo Find X9 Ultra Teardown
- SIM tray: Metal and plastic with dustproof and waterproof rubber seal.
- back: Oppo Find X9 Ultra with leather-like surface, glass decorative plate with aluminum ring, integrated camera lens cover.
- Camera protection: Multi-layered protection through seals, metal bezels and special Fresnel lenses for the flash.
- Thermal management:
- Extensive thermal interface materials (approx. 5500 mm² on the mainboard, increased by approx. 600 mm² compared to the predecessor).
- Thermal conductivity material inside the motherboard layers as a phase-change compound to stabilize the temperature.
- VC Vapor Chamber in the display area with an area of approximately 4900 mm², larger than its predecessor.
- Oppo Find X9 Ultra camera system:
- Three main cameras with a “board-breaking sunken” design, directly connected to the display and housing.
- Two periscope cameras with improved heat conduction measures.
- Second generation of the Danxia color restoration lens with DCG HDR support and improved 40 nm manufacturing technology.
- The front camera and ultra-wide-angle camera are mounted on the back of the motherboard.
- Motherboard:
- Multi-layer stack with up to five PCB layers and a large cavity for weight and heat optimization.
- Built-in Qualcomm Snapdragon 8 Elite Gen 5 SoC.
- Samsung LPDDR5X RAM with 10667 Mbps and UFS 4.1 storage.
- OPPO’s proprietary Shanghai communication chip.
- Daughterboard:
- Includes SIM tray, USB Type-C port (USB 3.2 Gen 1 with 5 Gbps, DP video output), 2 microphones and reinforcements for ports.
- Battery:
- Single-cell dual-connector solution, 7050 mAh (26.23 Wh), 950 mAh more than its predecessor.
- Energy density approx. 830 Wh/L (predecessor 792 Wh/L).
- Manufacturer: Dongguan NVT, ATL cells.
- 100W fast charger (max. measured charging power approx. 84.2W).
- Display:
- BOE LTPO OLED Panel, 2K resolution.
- 144 Hz refresh rate.
- Maximum brightness: approx. 800 nits full screen, 1800 nits in sunlight, 3650 nits with 10% window.
- New Goodix GUM5328 Ultrasonic Fingerprint Sensor.
- Touch IC: Synopsys S3910V.
- Acoustics:
- The top and bottom speakers utilize AAC’s Full-Cavity 1510X design with N’Bass® filling for improved sound.
- Four microphones in total (benchmark configuration).
- Structural and protective measures:
- 26 screws in 5 types.
- IP66, IP68 and IP69 certifications (additional IP66 high-pressure water jet test procedure compared to predecessor).
- Several rubber rings, sealing membranes and foam for dust and water resistance as well as noise reduction.
- Nano-injection molding and CNC manufacturing for aluminum alloy housings.
- X-axis linear motor:
- Model AAC ESA0816 (3rd generation), comparable to the larger ESA1016.
Conclusion and key insights
- Advances in heat dissipation and structural stability improve the performance and durability of the Oppo Find X9 Ultra.
- Innovative camera design The “board-breaking sunken” design allows for a compact construction despite large cameras.
- Battery capacity and charging speed were significantly improved.
- Display and fingerprint sensor upgrades ensure a better user experience.
- IP certifications were expanded, which increases robustness against water and dust.
- OPPO pursues a balanced strategy between portability and imaging performance, which is particularly noticeable with the 10x periscope lens.
- The miniaturization of components and the combination of functionality and design are Key features to highlight.
Overall, the teardown video concludes that despite improved imaging performance, the Oppo Find X9 Ultra makes no compromises in other core areas and offers a very well-balanced high-end flagship hardware package.
The Oppo Find X9 Ultra is the company’s flagship for 2026 and directly competes with the recently unveiled vivo X300 Ultra as well as to the older Xiaomi 17 Ultra.
These three are in a league of their own when it comes to camera quality, but one could of course also argue that the Oppo Find X9 Ultra compares to much more common models like the iPhone 17 Pro Max and the Samsung Galaxy S26 Ultra.
