TECNO is reimagining the smartphone not as a static “glass slab,” but as a dynamic hardware platform where users can physically swap components to match their immediate needs. At MWC 2026, TECNO introduced its Modular Magnetic Interconnection Technology.
TECNO’s modular system features an ultra-slim concept phone that measures just 4.9mm in thickness. It uses a stacking mechanism to expand hardware capabilities without increasing the device’s permanent footprint.
Core Concept:
Hardware Decoupling: Instead of a fixed configuration, the platform uses a 4.9mm ultra-slim base device that connects to high-performance modules via:
- Rectangular Magnetic Array (ensures secure alignment across eight specific “modular zones”)
- Pogo-pin Connectors (provide efficient, low-heat physical power transfer between the phone and the attached stack)
- Connection Architecture: Data is transmitted through a hybrid system using Bluetooth, Wi-Fi, and millimeter-wave (mmWave) for low-latency, high-bandwidth interaction.
- Design Editions: The concept was showcased in two styles: the clean, silver-aluminum ATOM Edition (silver/red) and the tech-enthusiast MODA Edition (dark grey/gold).
- Build: It features a matte glass finish and a precision-engineered rectangular magnetic array on the back to secure modules.
- Portless Design: Due to its extreme thinness, the device lacks a USB-C port and relies entirely on wireless charging or dedicated charging modules that attach via pogo pins.
Modular Features and Connectivity:
TECNO introduced this technology as a platform for future innovations, where hardware components can be swapped minute-by-minute.
Snap-on Modules: Planned accessories include:
- A 3,000mAh battery pack that would be expandable up to 10,000mAh.
- Telephoto lenses features its own sensor and OIS, providing 10x to 20x optical zoom.
- Action cameras: An independent unit for FPV shooting that clips to clothing and saves footage wirelessly to the phone.
- Walkie-talkie antenna designed to provide independent communication capabilities, ensuring connectivity even in areas without traditional cellular coverage.
- Power Bank: A 4.5mm pack that doubles battery capacity while maintaining a standard flagship thickness.
- AI Computing Module: Offloads intense thermal and power loads from generative AI tasks to prevent the thin base phone from throttling.
Other Noticeable Concepts
- TECNO SPARK Slim: Introduced as a concept in 2025, it measures 5.75mm (or 5.93mm depending on the report) and includes a 5,200mAh battery and a 144Hz AMOLED display.
- TECNO Phantom Ultimate 2: A tri-fold concept featuring a 9.94-inch display that folds twice, reaching a folded thickness of only 11.49mm. It uses a dual-hinge system to transition from a 6.48-inch phone to a 9.94-inch 3K tablet.
