The OnePlus Open 2 is poised to make waves in the foldable smartphone market with its groundbreaking ultra-thin design and remarkable durability. A collaboration with Oppo’s Find N5, this device is set to redefine expectations for what a foldable phone can achieve, blending aesthetic appeal with technological innovation. As competitors like Samsung and Google dominate the space, OnePlus is making its move to set a new benchmark in 2025.

The OnePlus Open 2 – Slimmest Foldable Yet?
A Revolution in Foldable Design
OnePlus Open 2 builds upon Oppo’s expertise in foldable technology, presenting a device thinner than anything seen before. Early teasers reveal that it outpaces rivals like the Honor Magic V3, which previously held the title for the slimmest foldable at 4.35mm when unfolded. Comparatively, the Open 2 measures just under 4mm when unfolded, nearly half the thickness of standard smartphones like the iPhone 16 Pro Max (8.25mm).

Dimensions and Key Metrics
To put its slimness into perspective, the OnePlus Open 2 is as thick as four stacked credit cards or two quarters. At 2.6mm around the USB-C port when unfolded, the device’s design sets new engineering standards. This slim profile ensures the Open 2 feels incredibly light and compact, ideal for on-the-go users seeking portability without compromise.
Engineering Challenges and Breakthroughs
The Role of the USB-C Port in Design Constraints
The device’s ultra-thin design is only achievable due to meticulous attention to engineering details. The USB-C port, which measures approximately 4mm, has been a significant limiting factor. Oppo and OnePlus engineers have optimized the internal layout, ensuring slimness without sacrificing essential features like connectivity and fast charging.
Battery and Hardware Optimization
Despite its thin profile, the OnePlus Open 2 boasts a larger battery compared to its predecessor, the Find N3. This approximately 20% improvement ensures users can enjoy extended usage without compromising on slimness. Advanced cooling systems and chipset efficiency contribute to maintaining performance in such a compact frame.
Durability and Water Resistance – A New Benchmark
IPX9 Rating Explained
The OnePlus Open 2 doesn’t just impress with its thinness; it also leads in durability with an IPX9 rating. This level of protection guarantees resistance against high-temperature, high-pressure water jets, ensuring the phone remains functional in challenging conditions. This feature sets it apart from competitors like the Galaxy Z Fold 5 and Pixel Fold.
What About Dust Resistance?
While the OnePlus Open 2 excels in water resistance, it lacks an official dust resistance rating. This omission might concern some users, especially those in dusty environments. However, the phone’s tightly sealed design likely offers practical protection in everyday scenarios.
The Global Release and Branding
From Oppo Find N5 to OnePlus Open 2
The Oppo Find N5, slated for a February release in China, forms the foundation of the OnePlus Open 2. While Oppo caters to the Chinese market, OnePlus takes the lead in global branding, targeting a Western audience. This strategic collaboration ensures the device reaches a broader demographic with localized marketing efforts.
Cultural Considerations in Naming
In line with cultural superstitions in China, Oppo skipped the “N4” naming convention, jumping directly to the Find N5. This decision underscores the importance of respecting regional traditions while maintaining global appeal.
Competitive Edge in the Foldable Market
How the OnePlus Open 2 Stands Out
By combining an ultra-slim design with unmatched durability, the OnePlus Open 2 distinguishes itself from rivals like Samsung’s Galaxy Z Fold series and Google’s Pixel Fold. Its slimness doesn’t compromise usability, offering a seamless user experience with cutting-edge features.
User Appeal and Target Audience
The OnePlus Open 2 appeals to tech enthusiasts and professionals seeking a premium, portable device. Its innovative design and durability promise to attract users who value both aesthetics and functionality.
Conclusion
The OnePlus Open 2 is not just another foldable; it’s a statement of what’s possible when design meets engineering. With its record-breaking slimness, enhanced durability, and thoughtful branding, it’s poised to reshape the foldable market in 2025. As more details emerge, the OnePlus Open 2 stands as a strong contender for the title of the best foldable smartphone of the year.
