TECNO is getting ready to launch its new innovation, the SPARK Slim, at the Mobile World Congress (MWC) 2025. The phone is designed to be the thinnest in the industry with a battery capacity of more than 5200mAh, marrying extreme thinness with durability. The SPARK Slim will be on show at TECNO’s booth, 6B11, Hall 6, Fira Gran Via.
Ultra-thin design and sustainable materials
The TECNO SPARK Slim features an extremely slim profile of only 5.75mm, ranking among the thinnest smartphones in the market. Made with fully recycled aluminum via an integrated die-casting technology, the phone showcases TECNO’s focus on environmentally friendly materials. The stainless steel unibody design not only offers improved strength but also provides an ergonomic feel for comfort.
Immersive display technology
The phone has a 6.78-inch 3D Curved AMOLED screen with a 1.5K (1224P) resolution and 144Hz refresh rate. This provides sharp images and smooth movement. The screen is clear and bright even in sunlight, with a peak brightness of 4500nits.
Battery life without compromise
In spite of being ultra-slim, the SPARK Slim features a 5200mAh dense battery for all-day use. The phone comes with 45W fast charging, allowing users to charge quickly without compromising portability. The thickness of the battery at 4.04mm is a testament to TECNO’s engineering expertise in optimizing performance and aesthetics.
Advanced camera system
The SPARK Slim has a dual rear camera system with two 50MP sensors that aim to shoot high-resolution photos with outstanding clarity. The 13MP front camera also boosts selfie quality and video calls. There is an interactive light band on the phone that gives the camera a dynamic visual effect, further improving the photography experience.
Performance and future prospects
Driven by a future high-performance octa-core processor, the SPARK Slim delivers effortless multitasking and long-lasting performance. The device’s fusion of style and technological advancement creates a new standard for ultra-thin smartphones. With TECNO pushing the limits of design, the SPARK Slim is a preview of the future of the brand’s smartphone series.
