I Tore Down the Oppo Find X9 Pro In China and It Completely Blew My Mind…
Today was not a normal teardown day. Oppo flew me from Canada to China to take apart their unreleased Find X9 Pro inside their own factory. They did not even tell me how to open it, so we were figuring this out live with engineers standing behind me.
The phone looks like a regular slab at 8.25 millimeters thick. But trust me, everything interesting is happening on the inside.
A Phone Loaded With Features We Do Not Get in the West
On the outside, the Find X9 Pro has two standout physical features.
Quick Button: This instantly opens the camera. It looks like a real button, but surprise, it is completely solid with haptic feedback doing all the work.
Snap Key: Another shortcut button up top that lets you trigger different functions.
As someone used to North American flagships, this thing feels normal so far. But opening it up made me realize how far ahead phone hardware is in China.
Opening the Find X9 Pro
We started with heat and a clamp because this phone has both IP68 and IP69 ratings. IP68 is for submersion. IP69 is for high pressure water jets and extreme temperatures. Translation: the adhesive is no joke.
Once the back glass lifted and we slid our prying card around the edges, the phone opened to a very clean internal layout with a pressure equalization membrane tucked inside the back glass.
A Camera System That Dominates the Inside
There are three main cameras plus a True Color camera sensor that helps the phone see colors accurately.
They are absolutely massive and take up a ridiculous amount of space. And that is just the start.
Here are the images taken from Oppo Find X9 with the True Color Camera Sensor.
Removing the Midframe
After removing all the Phillips screws, the midframe came off as one large unit. Everything on it connects using contact pads, so there are no flex cables to unplug.
At this point, the engineer behind me did not even have to explain anything. The internal design already looked different from basically any phone I have opened before.
The Floating Stack Architecture
Once the cameras were out, the main surprise revealed itself.
Instead of designing a standard motherboard with cameras placed in a separate island, Oppo wrapped the board around the modules. It almost feels like the camera block and motherboard are fused into one compact unit.
Oppo calls this a floating stack architecture. And it works because:
Every cubic millimeter is used. The board is 7 millimeters shorter than a normal layout. Shortening it gave space for the largest battery ever in a Find series phone. In fact, this is the tightest internal layout I have seen on a smartphone.
Inside the Logic Board
Under the copper shielding we found:
MediaTek Dimensity 9500 flagship chipset
16 GB of LPDDR5 RAM stacked over the SOC
512 GB of UFS 4.1 storage
Thermal paste applied in a Z pattern for better heat distribution
Everything here screams efficiency.
The Massive 7500 mAh Silicon Carbon Battery
This is where things get crazy.
The Find X9 Pro has a 7500 mAh silicon carbon battery. It is still lithium based, but it uses silicon carbon anodes instead of graphite so it can store a lot more energy in the same volume.
This gives you:
The largest battery ever put in a Find series phone
About 80 percent battery health after five years
Almost two days of battery life
Removing it was surprisingly easy thanks to a proper pull tab.
Lower Speaker, Vibration Motor, and Subboard
After digging deeper we reached the subboard. It includes:
The 80 watt USB C charging port
Dual microphones
A sea of red rubber gaskets to protect from water
The haptic motor and antenna cables
It is organized and decently repair friendly.
Is the Quick Button Repairable? Yes, Thankfully
I was curious about this because Apple laser welds their camera control button, making it unreplaceable.
Under adhesive and a rubber seal, the Quick Button actually pops out as a full module. It is replaceable. Oppo deserves credit here.
The Display Removal
We heated the front and used the clamp again because the bezels are only 1.15 millimeters thick. That is thinner than both Samsung and Apple.
| Feature | Details |
|---|---|
| Display Size | 6.78 inches |
| Refresh Rate | 120 Hz variable refresh |
| Brightness | 1 nit to 3600 nits |
| Fingerprint Sensor | 3D ultrasonic fingerprint sensor |
This thing is incredibly bright and well built.
The Giant Vapor Chamber
The last major piece is the vapor chamber cooling system inside the midframe. It is 33 percent larger than the previous generation, which explains why the phone stays cooler than many flagships I have worked on recently.
Feature Breakdown Table
| Feature | Specification | Notes |
|---|---|---|
| Battery | 7500 mAh, Silicon Carbon | Almost two full days of use; long-term health ~80% after 5 years |
| Processor | MediaTek Dimensity 9500 | Flagship SOC, highly efficient |
| RAM | 16 GB LPDDR5 | Plenty for multitasking and heavy apps |
| Storage | 512 GB UFS 4.1 | Super fast read/write speeds |
| Camera Setup | 50MP Main, 200MP Telephoto, 50MP Ultra-wide, True Color sensor | Huge camera sensors with advanced color accuracy |
| Buttons & Haptics | Quick Button, Snap Key, haptic feedback | Repairable quick button; fully haptic camera button |
| Display | 6.78-inch, 120 Hz, 1–3600 nits | Variable refresh, brightest display we’ve torn down |
| Charging | 80 W USB-C, 50 W wireless, 10 W reverse wireless | Insanely fast wired and wireless charging |
| Cooling | Large vapor chamber + copper sheet + thermal paste | 33% larger vapor chamber than previous generation |
| Water Resistance | IP68 & IP69 | Submersion proof and resistant to high pressure water jets |
Final Thoughts
Back at home, I realized how impressive this teardown really was. Oppo is playing a different game here.
The cameras are top tier. The screen is insanely bright. The battery is next level. And the internal layout shows engineering that pushes boundaries instead of recycling old ideas.
China is seriously ahead when it comes to smartphone hardware. Being invited to tear this phone down at the source was an awesome experience and something I could not have done without your support.
The Find X9 Pro battery is so big that I am convinced it secretly powers half the factory.
