Tecno has introduced the Spark Slim, a concept device that it claims is the world’s thinnest smartphone, measuring just 5.75 mm thick. Despite its ultra-slim profile, the phone packs dual 50MP cameras and a massive 5,200mAh battery, making it a standout in the mobile industry. However, the Spark Slim is currently just a concept, with no confirmed release date.
Tecno’s Spark Slim: A Game-Changer in Smartphone Design?
The Tecno Spark Slim is set to make its debut at the Mobile World Congress (MWC) 2025, where demo units will be showcased to industry experts and tech enthusiasts. While Tecno has not announced plans for a commercial release, the cutting-edge design and high-end features suggest a glimpse into the future of ultra-thin smartphones.
With a 6.78-inch AMOLED display, curved edges, and a 144Hz refresh rate, the Spark Slim aims to deliver an immersive viewing experience. Its 1224p resolution and peak brightness of 4,500 nits ensure vibrant colors and sharp visuals, making it one of the most visually impressive concept phones yet.

Challenges of Building an Ultra-Thin Smartphone
While the Spark Slim’s 5.75mm thickness is an engineering marvel, it presents unique challenges:
- Cooling Issues – High-performance processors generate heat, and with limited space for cooling systems, flagship-level chips seem unlikely for this design.
- Durability Concerns – Ultra-thin smartphones often face structural integrity issues, making them more fragile than standard models.
- Limited Hardware Integration – Larger components like advanced camera sensors and bigger speakers may not fit within such a compact body.
Despite these challenges, Tecno’s breakthrough in thin smartphone design signals exciting innovations for the industry.
