Infinix NOTE Edge: A Mid‑Range Powerhouse Powered by MediaTek’s Dimensity 7100

Infinix has just raised the bar for budget‑friendly 5G smartphones. The newly announced NOTE Edge is the first device to ship with MediaTek’s 4 nm Dimensity 7100 chipset, delivering flagship‑class performance while staying comfortably below the $400 mark. With a sleek retro‑inspired silhouette, a 6.78‑inch curved AMOLED panel, a 50 MP main camera, and a massive 6,500 mAh battery that charges at 45 W, the phone feels more premium than its price suggests.

Design Language That Stands Out

The NOTE Edge abandons the bland slab look that dominates the mid‑range market. Its sloping, curving side panels create a distinctive, almost nostalgic silhouette that’s both eye‑catching and ergonomic. At just 7.2 mm thick, the device feels light in the hand, and an IP65 rating protects it from dust and low‑pressure water jets—features you’d normally expect on higher‑end flagships.

Display: Curved, Crisp, and Fast

Under the glass sits a 6.78‑inch AMOLED screen with a 1.5K resolution (2400 × 1080). The panel curves gently along the edges, reinforcing the phone’s retro vibe while delivering vibrant colours and deep blacks. A 120 Hz refresh rate makes scrolling buttery smooth and gives games a noticeable edge, especially when paired with the Dimensity 7100’s 90 fps gaming support.

Performance: Dimensity 7100 Takes the Lead

MediaTek’s Dimensity 7100 is built on a cutting‑edge 4 nm process, promising high CPU performance without draining the battery. The octa‑core architecture handles multitasking with ease, and benchmark tests consistently push past 810,000 points on AnTuTu V11—well ahead of most competitors in the same price bracket.

Gaming gets a boost, too. The chipset’s efficiency lets titles run at 90 fps or higher while keeping thermal output low, meaning you won’t be forced to throttle performance after a few minutes of intense play.

Camera System: More Than Just Megapixels

The rear camera array is anchored by a 50 MP primary sensor, complemented by ultra‑wide and macro lenses. While detailed sample shots are still emerging, the high‑resolution main sensor should deliver sharp, detailed images that rival many mid‑range rivals. On the front, a 16 MP punch‑hole selfie camera handles video calls and portraits without fuss.

Battery Life and Charging: All‑Day Power

A 6,500 mAh battery sits behind the display, promising all‑day endurance even under 5G traffic. When the charge does run low, the 45 W fast‑charging solution refills the battery in roughly an hour, minimizing downtime for commuters and power users alike.

Audio, Connectivity, and Build Quality

• Audio: JBL‑tuned stereo speakers provide richer, balanced sound compared with the mono setups common in this segment.
• Connectivity: Full 5G band support, Wi‑Fi 6, Bluetooth 5.3, NFC, and the IP65 rating round out a robust connectivity suite.
• Build: The combination of a curved glass front, aluminium‑ish side panels, and the IP rating gives the phone a premium feel despite its modest price.

Software: Android 16‑Based XOS 16

Running on Android 16‑based XOS 16, the NOTE Edge offers a clean UI with AI‑driven optimisations that help squeeze extra performance from the Dimensity 7100. Infinix has pledged long‑term software updates, meaning users can expect future Android upgrades and regular security patches—an uncommon promise for phones under $400.

Market Impact: Raising the Mid‑Range Ceiling

By integrating the Dimensity 7100, Infinix is challenging the dominance of Samsung, Xiaomi, and Realme in the sub‑$400 5G arena. The blend of a high‑refresh‑rate curved display, flagship‑grade camera hardware, a sizable battery, and premium audio creates a value proposition that forces competitors to rethink their own spec sheets.

Practitioners Perspective

From a developer’s standpoint, the 4 nm Dimensity 7100 opens doors for more demanding mobile‑first applications. Its efficient cores mean background AI tasks—like real‑time translation or on‑device image enhancement—won’t sap the battery as quickly as older mid‑range chips. For gamers, the 90 fps support combined with the 120 Hz panel translates to smoother frame pacing, reducing motion blur and giving a competitive edge in fast‑paced titles.

Field technicians will appreciate the IP65 rating and the modular design of the side panels, which simplify repairs compared with sealed slab phones. The large battery also means fewer charge‑cycle replacements over the device’s lifespan, lowering long‑term maintenance costs for enterprise deployments.

Final Thoughts

The Infinix NOTE Edge proves that you don’t need to break the bank to enjoy flagship‑level experiences. With MediaTek’s Dimensity 7100 at its heart, a curved 120 Hz AMOLED display, a solid camera suite, and a battery that can truly last a day, the phone feels like a premium device masquerading as a budget offering. If Infinix can keep its software promises, the NOTE Edge could set a new benchmark for what consumers expect from sub‑$400 smartphones.
