Staff Reporter : Why are book-style foldables so revolutionary? It’s simple: they combine an expansive tablet-style display with the smartphone experience we know and love, but this typically comes at a cost: foldables aren’t as thin, light, or durable as bar phones.
While there has always been a trade-off when it comes to foldable design and durability, OPPO’s Find N series has consistently redefined expectations, pushing the boundaries of what’s possible. And when the technology to create an even thinner, more durable foldable didn’t exist, OPPO innovated and found a solution.
This journey of continued innovation has led us to OPPO Find N5. Delivering the thinness, lightness and long-term reliability typically reserved for top-tier flagship bar phones, Find N5 marks a key point in foldable history and delivers a seamless two-in-one experience.
At just 8.93mm, Find N5 is the world’s thinnest book-style foldable flagship smartphone. It’s 26% thinner than its key competitor in the space and the first book-style foldable less than 9mm thin when folded. Its slim profile is more comparable to flagship bar phones than some current-generation foldables, illustrating just how far ahead of the competition it is.
When unfolded, Find N5 measures just 4.21mm thin, barely thicker than a USB-C port. Achieving this ultra-slim design required custom-designed components, each engineered to fit inside Find N5’s record-breaking body. In fact, Find N5 is one of the thinnest personal electronic devices in the world when unfolded despite all the power and potential within; a truly remarkable achievement.
Find N5 is also the lightest book-style Find N device to date, weighing just 229g1 that’s 10g lighter than the key competition. In fact, its weight is closer to that of the bar flagship phones, proving that OPPO foldables can deliver compromise-free in-hand experiences compared to non-folding phones while beating the competition.
This extreme thinness and lightness ensure that Find N5 eliminates the bulk and discomfort typically associated with foldables. It feels as natural as a bar phone, with its ultra-thin design fitting effortlessly into a pocket and small bag and its ultra-light body never weighing you down, whether open or closed, in one hand or two.
The Ultimate Challenge: Slim Yet Strong : To achieve ultimate thinness without compromising reliability, every aspect of Find N5 has been meticulously engineered, pushing the limits of foldable design.
The hinge is the backbone of a foldable, defining its structure and long-term durability. Find N5 introduces OPPO’s most advanced and durable hinge yet: the Titanium Alloy Flexion Hinge.
Both the hinge cover that protects the internal parts of the hinge and the wing plate that connects the hinge to the folding screen are 3D printed for exceptional accuracy from aerospace-grade Grade 5 titanium alloy. This is the same material used in the Boeing 787 and Mars Exploration Rovers. Compared with the previous generation, Find N5’s Titanium Alloy Flexion Hinge delivers 36% higher rigidity while being 26% smaller.
Find N5 has earned the TÜV Rheinland Reliable Folding Certification, a testament to its exceptional durability in extreme conditions. Thanks to its robust Titanium Alloy Flexion Hinge and reinforced structural design, the device has undergone rigorous testing, including 100,000 folds at temperatures of 50°C and -20°C. This certification assures users that Find N5 is built for long-term reliability, maintaining smooth folding performance even under demanding conditions.
Find N5’s frame is crafted from customised 7000-series aluminium, a material that is 30% stronger than the previous generation, reinforcing the structure while maintaining a slim profile. The back cover, made from advanced aerospace-grade fibre, is 43% thinner than the previous generation yet more resilient in drop tests.
Inside, the battery compartment is supported by carbon fibre and aluminium-ceramic composite materials, reducing thickness while enhancing structural strength. Meanwhile, the quad-stacking motherboard design maximises space efficiency – 20% thinner and 31% shorter than its predecessor – pushing compact engineering to a new level.
For the inner display, where durability is a top priority, Find N5 introduces a Dual Shielded Flexible Screen featuring two layers of protection. A key innovation is the exclusive anti-shock film, made from elastomer material that absorbs impact forces and returns to its original shape, providing 70% stronger shock resistance.
The First Foldable with IPX6, IPX8 and IPX9 Water Resistance : Water resistance has always been a greater challenge for foldables than for bar phones, but Find N5 overcomes this limitation. It is the world’s first foldable smartphone to achieve IPX6, IPX8, and IPX9 certifications. Whether caught in the rain or accidentally dropped in water, Find N5 is built to handle real-life situations with ease.
To achieve this level of water resistance within its compact body, Find N5 incorporates an innovative multi-layer waterproof structure. Adhesive backing and precision dispensing create the first level of sealing, ensuring moisture stays out, after which more fluid adhesive is also applied, extending curing time and forming a more secure bond. Integrating advanced waterproof materials further enhances long-term water resistance and makes Find N5 truly real-life-ready.
Find N5 once again demonstrates OPPO’s relentless pursuit of excellence. Combining cutting-edge materials, precision engineering, and advanced structural design, OPPO redefines what a foldable smartphone can achieve.
Through continuous innovation, the Find N series has transformed foldables from a novelty tech showcase to a reliability powerhouse for the first time, proving ultra-thin design and long-term durability are possible while making them a better choice for more users than ever before.
