TECNO unveiled the ultra-thin SPARK Slim smartphone at MWC 2025

At the Mobile World Congress 2025 in Barcelona, TECNO presented the conceptual SPARK Slim smartphone, distinguished by its ultra-thin design, premium materials, and high battery life. The device has a thickness of just 5.75 millimeters, making it one of the thinnest in the industry. The body is made from recycled aluminum and stainless steel, ensuring lightness and durability.

The smartphone guarantees clear images and smooth scrolling even in bright sunlight. The main dual camera with a resolution of 50 MP handles photography, while the 13 MP front camera ensures high-quality selfies and video calls. A distinctive feature of the device is the interactive light strip between the rear cameras, adding a unique visual effect.

Despite its ultra-thin body, the SPARK Slim is equipped with a 5200 mAh battery, which has a thickness of only 4.04 millimeters. TECNO promises that this capacity will last a full day without recharging. The smartphone also supports 45W fast charging.

At present, the SPARK Slim remains a conceptual device, and its commercial launch is not currently planned. However, TECNO is considering the possibility of applying the developed technologies in future mass-produced models. The smartphone will be one of the company's main showcases at MWC 2025, reflecting its vision for the future of ultra-thin mobile devices.
