TECNO's 4.9mm modular phone wins IFA gold

TECNO's ultra-thin Modular Phone remains one of the standout experimental smartphones from IFA 2026 after receiving a Global Product Technology Innovation Gold Award. The concept is just 4.9mm thick yet uses a proprietary magnetic array and pogo-pin interface to attach specialised external modules. TECNO is exploring modularity partly as a way to add AI, camera and other hardware capabilities without permanently making the base phone thicker.

Modular smartphones have repeatedly struggled commercially because accessory ecosystems rarely become large enough to justify proprietary hardware. TECNO's design is nevertheless interesting because it approaches the problem from the opposite direction: keep the phone unusually thin and let users add physical capability only when required. The concept remains an experimental product rather than a confirmed mass-market launch.

Even if this exact handset never reaches stores, modular attachment systems could influence future accessories as smartphones run out of internal space for larger batteries, cooling and specialised AI hardware.
