The OnePlus Nord 4 has something no other OnePlus phone has ever had | Digital Trends

Our conversation began with the design, which sparks a heavy dose of nostalgia. Phones with metal bodies dominated the latter half of the 2010s, but were eventually phased out in favor of glass or plastic attires, leaving enthusiasts like me mightily unfulfilled.

I inquired about what led to the choice of material. Liu told me the route back to metal was inspired chiefly by four qualities it brings, namely “durability, beauty, permanence, and strength.” Understandably, metal phones don’t as easily succumb to hard drops and are harder to break. While the beauty of a refined metal surface may be subjective — and rightly lies in the eyes of the beholder — they are inarguably more resistant to the effects of time, such as micro scratches, that develop on glass phones after constant use.

Metal also improves performance, with the outer body acting as an effective surface to dissipate heat generated during tasks such as gaming. While that may mean your phone is likely to feel hotter while you use it, it will also cool down faster than most glass back phones. By preventing heat from being trapped inside the body, it will also prevent damage to the internal components over prolonged usage.

So, what led to the ousting of metal phones and the dominance of glass as the preferred material for premium phones? I asked Liu, who responded, “Metal phones were all the rage before 5G networks. But as 5G gained popularity, smartphones needed more antennas.” Compared to just four antennas on the OnePlus 3T, the OnePlus 12 has more than 13.

The larger number of antennas leads to challenges with accommodating more within the body. Meanwhile, metal bodies would interfere with the combined signals from these antennas, and that is why companies began to prefer glass or plastic, while the use of metal remained limited to the side rails.

This made me curious about what changes now and how OnePlus was able to achieve a metal build without impacting 5G signals. Liu informed me of overhauled antennas that are now 50% smaller than before. More importantly, OnePlus redesigned the motherboard and placed these antennas strategically, so the Nord 4’s body does not impede cellular signal. In addition, the phone has plastic inserts in places such as the bottom of the back to reinforce signal strength.

Besides ensuring signal strength, OnePlus has also created a metal design with microscopic ridges that appear like bumps, but result in a plain surface. That is something glass suffers a lot with, even on the most premium phones and despite the strongest Gorilla Glass — or similarly strong — protective layers.

But the OnePlus Nord 4 is about more than just a design change geared for endurance. The software plays a crucial role, too. In fact, it comes with the promise of the “longest-ever software support package” from OnePlus.

Liu confirmed the OnePlus Nord 4 gets four years of Android updates, launching with Android 14 and going up to Android 18 (or equivalent). Additionally, OnePlus will provide two more years of software support for crucial feature updates, including security patches. That brings the total support to six years, which is longer than any OnePlus phone in the past. This is a step up from the OnePlus Nord 3, which was promised three years of Android updates and an additional year of security updates.
