Infinix has long been a champion of innovation, designing exciting smartphones that are affordable to the masses, but the brand has broken new barriers with its stunning new NOTE 50 series. This phone draws inspiration from high-end automotive design principles and is crafted with a new premium metal that delivers a refined, luxurious feel. The frame is made out of ultra-resilient ArmorAlloy™, providing superior shock-absorption for unparalleled durability. This unique material is a blend of premium military-grade Damascus steel and aerospace-grade aluminum, which is lightweight as well as exceptionally resilient. Usually limited to industrial applications, Infinix is leading the way by bringing it to the masses with the NOTE 50 series.

As Professor Robert Maass, an expert in metallic materials at the prestigious Technical University of Munich, explains: "Borrowing the concept of a two-materials marriage from automotive manufacturing is a great way of getting the best from both worlds: a classical, highly performing steel and a lightweight but also high-strength aluminum alloy."

Putting this concept into practice when designing a phone is a unique achievement. "Joining these two dissimilar metals typically poses metallurgical challenges," says Maass. "Implementing it in smartphones is far from easy... Yet, Infinix engineers made it happen."

He notes that the blended alloy approach adopted by Infinix offers a distinct weight advantage, while protecting smartphones from accidental damage due to impact events. "Using synergistically two high-performing alloys in a composite is really forefront. I see this often in research-grade materials, but not so much in actual applications," Maass says. "Infinix bringing such innovations to the consumer market is a wonderful example of how materials science continuously enables new functionalities and more reliable products everyone profits from. "

Furthermore, this new phone moves the market in a more sustainable direction. "Steel and aluminum boast the highest recycling rates among all metals," notes Maass. "Any step toward improving recycling rates is a major win."

The NOTE 50 series offers an eclectic mix of exquisite technical artistry, uncompromised performance, powerful imaging, stunning OLED visuals, super-fast charging chops, and next-gen implementation of AI tools. Available in five trim packages, this new line is redefining what a budget smartphone can accomplish, with impressive options ranging from just $180 to $370.

As the ultimate showcase of engineering acumen, Infinix created special Racing Edition variants in partnership with a prestigious automotive design team that specializes in high-performance vehicles. These exquisite limited edition models of the Infinix NOTE 50 Pro combine a sleek metallic frame with a zircon sand back cover, offering surface grip with a stunning gradient finish. The Note 50 Series is also available in titanium grey and enchanted purple. "The color range is spectacular, which stands out next to the otherwise understating noble design," says Professor Maass.

With the tagline "Performance. By Design," the NOTE 50 Series exemplifies the seamless fusion of cutting-edge technology and artistic craftsmanship. The rear camera module features a distinctive octagonal shape, introducing a high-end geometric language that reflects balance, precision, and strength. Far beyond a functional zone, this design signature anchors the device's entire visual identity.

The innovative HyperCasting forging process used in crafting the NOTE 50 series was also inspired by the manufacturing philosophy of high-end automotive brands like Tesla. Tesla pioneered the use of large integrated castings in its electric vehicles, merging multiple structural components into one, thereby reducing the number of parts and assembly steps, increasing production efficiency, and lowering manufacturing costs. Moreover, integrated casting enables lighter vehicle bodies, improving overall range and performance—an innovation that has shaped the direction of modern car manufacturing.

The TÜV SÜD-certified ShockAbsorb design leverages ArmorAlloy's composite properties to significantly extend the phone's lifespan, even after accidental drops. "HyperCasting is a state-of-the-art technology that simplifies the phone's structure by eliminating joints—often the weakest parts—resulting in a stronger, more reliable unibody design," says Maass.

"Borrowing the concept of a two-materials marriage from automotive manufacturing is a great way of getting the best from both worlds: a classical, highly performing steel and a lightweight but also high-strength aluminum alloy," Maass notes.

This automotive-inspired approach allows Infinix to reduce 22 structural components in the phone's frame, resulting in a lighter yet stronger device that maintains premium feel and exceptional durability.

As an added dash of convenience, you can still interact with the Infinix NOTE 50 Pro+ 5G's gorgeous display panel even when it gets wet or your fingerprints get greasy. The entire kit also offers IP64-level protection against dust and water ingress. You don't have to worry about on-device security, either. Infinix has equipped its latest model with an in-display fingerprint sensor for seamless biometric authentication.

And as the ultimate showcase of engineering acumen, Infinix also created special Racing Edition variants in partnership with a prestigious automotive design team that specializes in high-performance vehicles. These exquisite limited edition models of the Infinix NOTE 50 Pro combine a sleek metallic frame with a zircon sand back cover, offering surface grip with a stunning gradient finish.

The NOTE 50 series could probably get by on looks alone, but Infinix has not forgotten that above all else, a smartphone needs to focus on performance and convenience. The new line includes some standout features that are a rarity in the segment, especially at this low price point.

Surprisingly, while metal designs often compromise signal quality, the NOTE 50 Pro+ 5G maintains strong performance without signal interference. It even supports 5.5G speeds with stable connectivity. Equipped with GPS L5 for enhanced accuracy and anti-interference, it performs reliably in both urban and wooded environments. Meanwhile, the MIMO dual-antenna system boosts Wi-Fi speed, lowers latency, and ensures a more stable connection—ideal for gaming, streaming, and browsing.

The NOTE 50 Pro+ 5G, is one of the fastest charging phones on the market and can double as a power bank to top up your other accessories. Thanks to the PowerReserve reverse charging system, the Infinix flagship can juice up another device, including iPhones, at a 10W output.

Don't see a USB-C cable around you? There's a solution for that, as well. The in-house PowerReserve reverse charging tech also works in wireless mode. All you need to do is put another battery-depleted gadget atop the Infinix phone, and it will come back to life, thanks to 7.5 wireless power transfer output. That's the same output you get from a baseline Qi-certified wireless charging hardware. In a nutshell, you are not just investing in a refined Android phone, but one that serves as an emergency power backup, too.

The innovation doesn't stop there. The Infinix NOTE 50 Pro+ 5G and NOTE 50 Pro can also serve as wellness wearables. A dedicated sensor array capable of heart rate and blood oxygen monitoring is located underneath the rear camera lenses. Thanks to this unique on-phone approach, you can assess real-time biomarkers and perform health tracking without having to rely on other devices.

The Infinix NOTE 50 series embraces AI with its in-house Infinix AI∞ stack, which allows users to summon the Folax AI agent with a single or voice command.

Powered by the disruptive DeepSeek R1 AI model, the Folax agent can handle everything from creating travel plans, to extracting minute details from documents, to interacting efficiently with other apps. With a voice command, you can send a message through WhatsApp or share files via email.

Contextual understanding is the biggest strength of Folax, and thanks to its multi-modal capabilities, it can understand the world around it, as seen through the Infinix Note 50 series' camera or whatever appears on the screen. Users can scan the picture of a delicacy, and the onboard AI will deliver everything from the recipe and cooking instructions to translating the accompanying text. Capable of performing over a hundred tasks that an average smartphone user runs into on a daily basis, One-Tap Infinix AI∞ redefines the boundaries of what a smartphone can accomplish for you.

The photography on this phone is no joke, either.
