With the way how cameras on the back of the phones seem to be dancing around, or how every new model has some innovative glass-etching process, you’d think that the smartphone design field is bursting with activity and changing at every turn. You’d be partially correct, at least if only external appearances are concerned. In one important aspect, however, phone design has somewhat stayed still, held back by the demands of technology. Phones these days are either made up of glass and plastic covers on top of metal or plastic frames, with all-metal designs almost just a footnote in history. As one that never settles for anything less, OnePlus embarked on a bold and ambitious quest to design the first and so far only 5G phone with a metal unibody, a journey that took them back not only through the history of smartphone design but also through the history of human innovation.
Designer: OnePlus
Mobile Innovation, Material Stagnation
It wasn’t always the case that smartphones had a singular formula when it came to materials. It wasn’t too long ago that OnePlus itself launched a metal unibody design in the form of the 2017 OnePlus 5 and OnePlus 5T. Since then, however, smartphones have moved to those glass-metal or plastic sandwiches and there hasn’t been a full unibody design ever since. Ironically, the reason for that is one of the biggest innovations in the mobile industry: 5G networks.

The speed and power of 5G placed heavier demands not just on hardware but also on design, specifically on how radio waves are transmitted through the phone’s body. Wireless signals already have a difficult time passing through metal, and even more so for 5G, forcing phone designers to either have plastic strips on the frame’s edges or simply ditch the all-metal design altogether. Unfortunately, it almost seems as if the industry as a whole is no longer interested in solving this puzzle, but OnePlus has risen to the challenge to provide its loyal users with a no-compromise option that will speak to their hearts through their fingers.
Metal Matters
Since the beginning of human history, especially when it came to trade, metal has played an important role not just in building up civilization but also as a symbol of prestige and luxury. Metal has always had this dual character of being a durable and malleable worker’s tool as well as a premium material for jewelry, decorations, and art. It is this long history that has endeared French designer Mathieu Lehanneur to metal. Famed for his nature-inspired metal-based works, Lehanneur was chosen to design the distinctive Paris 2024 Olympic Torch, perfectly symbolizing not only the aspirations of the Olympics itself but also the poetry in nature found in this year’s location for the event.

“I love materials that get their own history,” says Lehanneur as he explains his fascination with metal, “and metal’s history actually starts from the Earth, from the very planet itself. At the same time, it is also a part of human invention and skill, thanks to its ability to be transformed. I love the flexibility of the material, being able to create something that appears like a single piece of metal, a unibody design like the Olympic torch.”
It is that same trait that has allowed OnePlus to craft a seamless and unified metal shell for its latest design, the OnePlus Nord 4. The material delivers a lustrous look and a premium feel, something that users today are craving more than just features and specs. More importantly, however, this metal unibody design was made to address the flaws and concerns that smartphone makers have with mixing the material and current technologies, opening the door to fresh new designs that go beyond limitations imposed by hardware.
OnePlus Nord 4: Metal for the 5G Era
Choosing metal for the new Nord was both logical yet also difficult. It presented an opportunity to uplift the user experience but also put hurdles that needed to be sufficiently overcome lest it actually become a burden to that same user experience. Fortunately, the creative minds over at the OnePlus Industrial Design Studio got together to solve these issues to deliver a fashionable product without compromises.
Ryan Ruan, Head of OnePlus Industrial Design Center, shares the many challenges the team had to face and eventually solved to create the OnePlus Nord 4. In the early stages of the design, it was already clear that the higher thermal conductivity of metal would be a concern. “That’s why we chose the power-efficient (Qualcomm) Snapdragon 7+ Gen 3 and designed a heat dissipation system that uses 17,900 sq. mm. of high-density crystalline graphene and a steel vapor chamber to ensure that even in extreme temperatures, the phone can still operate normally,” the designer explains. This serves to minimize the impact of heat on the metal surface and keep the phone performing optimally.
Wireless charging is another feature that is absent on phones with metal covers, and, unfortunately, there is still no way around this limitation. That said, the desire for this feature is more of a symptom of a much deeper cause. “Ultimately, users are pursuing high charging efficiency and a better user experience overall. Wireless charging is just one of the solutions, but we provide another solution,” according to Ruan. That solution is the OnePlus Nord 4’s extra-large 5,500 mAh battery and super-fast 100W SuperVOOC charging, minimizing not only the charging time but also the number of times you even need to charge the phone.
As for that tricky 5G antenna problem? OnePlus re-designed the phone’s internals to not only maximize battery space but also improve the signal strength. More importantly, the new U-shaped antenna design at the bottom of the internal chassis ensures that there is no degradation of wireless signals when you hold the phone at the sides with the so-called “Death Grip.” In other words, there will never be a wrong way to hold the Nord 4.
The Future of Burdenless Design
“When you choose a device, a product, or an art piece, it’s not only a question of specs or functionality but also a question of emotion, what you can feel from an object,” says Lehanneur. This relationship between object and person is especially true with today’s smartphone users who no longer pick just from a list of features but based on, as the designer describes it, “a question of how you want to be part of this object and how you want it to be a part of your life.” In that regard, Lehanneur expressed his delight in the Nord 4’s metal unibody design, and not just because it was made of metal. The Mercurial Silver colorway, in particular, has this visual effect where you can feel a relief or embossed surface even when there’s none. Lehanneur compares it to the “guillochage” design of luxury watches that provide beautiful visual and tactile experiences in a simple yet striking manner.
It’s a kind of detail that isn’t lost on OnePlus users who Ruan describes as “very playful, very young, and very personalized, pursuing designs where they can express themselves.” That is why early on, OnePlus designers decided to have a very different metal unibody design for the Nord 4 that distinguishes it from the 4G era OnePlus 5 and 5T. The dual-tone design of this generation’s “Nordtones” expresses that spirit of dynamism and vibrancy, while still trying to appeal to a broad range of tastes. It allows the Nord 4 to establish an emotional connection with users and allow them to express themselves in more unique and personalized ways.
A metal unibody is definitely a bold design to use for a phone, but it’s one that looks to the past glories of smartphone history while also safeguarding its future. “Metal is probably one of the most sustainable materials because it can live endlessly,” says Lehanneur. Unlike plastic that loses a part of its substance every time it’s recycled, metal can be recycled again and again. The recycled metal used in the Paris Olympic Torch, for example, could have very well come from a car in the past. In a way, that is also one way that metal carries its history, creating an interesting narrative with each lifetime.
In the same vein, metal wasn’t just a material choice for OnePlus but a representation of the brand’s design philosophy and ideals. “OnePlus is founded on the belief that while form should always perform a function, good design is what ultimately defines the user experience,” says Ruan. Choosing a metal unibody design, despite its numerous challenges, demonstrates the battle cry that launched OnePlus into stardom: Never Settle. “Our aim is to always strike the ideal balance between modern, elegant design and fast, smooth performance while providing users with a burdenless experience.”
