TECNO Slim 2 at MWC 2026: A groundbreaking 5.49mm ultra-slim body with a 6150 mAh battery.
At MWC 2026, TECNO attracted attention by introducing the Slim 2, a smartphone that is only 5.49mm thick but boasts a high-capacity battery and a unique dot-matrix display.
Following the success of the SPARK Slim concept smartphone at MWC 2025, TECNO officially introduced its successor, the TECNO Slim 2, at MWC 2026. This device continues to push the boundaries of physics by reducing the body thickness to just 5.49mm, significantly thinner than the 5.75mm of its predecessor.

Premium ceramic casing design and record-breaking slimness of 5.49mm.
The TECNO Slim 2 makes a strong impression on users at first glance thanks to its ideal slimness. Unlike many thin and light smartphones that often use plastic or glass, the prototype displayed at MWC 2026 is made from ceramic material. This casing not only provides a solid, premium feel in the hand but also ensures structural durability for a device with an ultra-thin body.
Despite its minimalist size, the TECNO retains responsive physical keys and a standard USB-C charging port. The screen bezels have also been refined to be thinner, creating a symmetrical visual effect and seamlessly blending into the device's unibody ceramic frame.

144Hz AMOLED display and hardware performance
In terms of display capabilities, the TECNO Slim 2 uses a high-quality AMOLED panel with a 144Hz refresh rate, providing a smooth touch experience. This screen boasts a maximum brightness of up to 4,500 nits, ensuring clear content even in bright light. Inside, the device houses a MediaTek Dimensity 7100 processor supporting 5G connectivity, guaranteeing stable performance for everyday tasks.
Key features include a 6150 mAh battery and a unique dot-matrix display.
The most impressive engineering achievement on the TECNO Slim 2 is the integration of a 6,150 mAh battery into a body that is only 5.49mm thick. This is a significant improvement over the 5,200 mAh battery in its predecessor, effectively solving the trade-off between slimness and battery life.

The back of the device features a distinctive visor-style camera module housing a 50MP main sensor. Notably, TECNO also incorporates a small dot-matrix display with an LED strip below, allowing for the display of customizable emojis and notification effects, creating a unique aesthetic and functional feature.
