TECNO’s 4.9mm Modular Smartphone Concept at MWC 2026

What if your phone could grow with you — literally? TECNO is heading into MWC 2026 with one of the boldest smartphone ideas in years: a 4.9mm-thin modular phone built around magnetic snap-on hardware modules that physically expand what your device can do.

How the Modular System Actually Works

The TECNO Modular Phone uses a hybrid connectivity architecture — physical attachment and power delivery happen through a magnetic array and pogo-pin connectors, while data is routed automatically via Wi-Fi, Bluetooth, or mmWave depending on the module’s bandwidth requirements.

The rear panel is visually divided into eight modular zones using subtle lines that serve as physical alignment guides for attaching accessories. The most compelling module might be the power bank — at just 4.5mm, it doubles battery capacity while keeping the total combined thickness comparable to a regular non-modular smartphone.

TECNO has confirmed the architecture is designed to eventually support expanded storage, dedicated AI computing tools, and lifestyle accessories, with potential for broader compatibility beyond the TECNO ecosystem in the future.

This is TECNO’s answer to AI’s growing compute demands on mobile hardware — rather than cramming more silicon inside, it snaps it on the back.
