TECNO SPARK Slim to Debut at MWC: World’s Thinnest 5.75mm Phone with 5200mAh+ Battery

TECNO is set to unveil the SPARK Slim at MWC 2025, a ultra-thin concept smartphone that pushes the boundaries of smartphone slimness while delivering powerful performance. As the industry’s slimmest device with a 5200mAh+ battery, TECNO SPARK Slim will lead the way in the next wave of ultra-thin smartphone design. Attendees will be able to see the innovation for themselves at TECNO’s MWC 2025 booth.

The SPARK Slim concept features an ultra-sleek 5.75mm profile, a stunning 6.78-inch 3D Curved AMOLED display, and futuristic sustainable materials that offer a refined yet ergonomic feel. Its advanced 50MP+50MP dual rear camera and 13MP front camera are complemented by an interactive light band, creating a dynamic, humanized lighting effect.

Setting a New Record for Smartphone Slimness

While many ultra-thin smartphones trade endurance for design and portability, leaving users with single-day battery life, the SPARK Slim doesn’t lead to a trade-off. Despite being just 5.75mm thick, SPARK Slim houses a powerful 5200mAh battery, delivering all-day energy in an extremely portable form. 

Its sleek design harmoniously combines sustainable luxury with technical precision. The device is crafted from fully recycled aluminum using an integrated die-casting process and features a stainless steel unibody– advanced materials that not only elevate the tactile experience with a luxurious feel but also enhance the ergonomic, integrated design. The result is a sleek, lightweight device that ensures a smooth, comfortable grip, offering a perfect balance of refined, futuristic aesthetics and practicality for an effortlessly enjoyable user experience.

Making the design even more captivating, the SPARK Slim features a 6.78-inch 3D Curved AMOLED display with stunning 1.5K (1224P)  resolution and a 144Hz refresh rate, delivering crisp, vibrant detail and ultra-smooth navigation. A peak brightness of 4500nits ensures ultra-clear visuals even under bright sunlight. This innovative combination of cutting-edge display technology and ultra-thin craftsmanship creates a true statement piece, delivering a large, immersive screen experience while maintaining its sleek form.

Uncompromised Power in an Ultra-Thin Form

Despite its exceptionally slim form, the SPARK Slim delivers uncompromised power with a 4.04mm thick, high-density 5200mAh battery. Boasting an impressive 45W fast charging, the device ensures worry-free, all-day usage, keeping users effortlessly connected and powered throughout their day.

Beneath its refined exterior, the SPARK Slim is powered by an upcoming high-performance octa-core chip, engineered to deliver a smooth experience and exceptional endurance. Every interaction flows seamlessly, enabling extended use without interruption.

On the camera front, SPARK Slim’s advanced camera system elevates mobile photography with a 50MP+50MP dual rear setup, designed to capture every detail with stunning clarity. A dynamic light-band effect enhances the shooting experience, adding a futuristic and expressive touch. The 13MP front camera ensures high-quality selfies and video calls, making every shot effortlessly brilliant.
