The TECNO SPARK Slim is set to debut at the Mobile World Congress 2025 (MWC 2025) in Barcelona. This revolutionary concept device, scheduled for debut on February 28, 2025, is positioned to establish a new benchmark in ultra-thin smartphone design while maintaining impressive performance capabilities.
TECNO SPARK Slim
The TECNO SPARK Slim distinguishes itself as the world’s thinnest smartphone with a substantial battery capacity, measuring a mere 5.75mm in thickness while housing a 5200mAh+ power cell. This remarkable engineering achievement addresses one of the most persistent challenges in slim smartphone design—battery life—offering users both portability and longevity in a single device.
Attendees at MWC 2025 will have the opportunity to experience this innovation firsthand at TECNO’s booth 6B11 in Hall 6 of Fira Gran Via. The concept phone features a sophisticated 6.78-inch 3D Curved AMOLED display with 1.5K resolution and a fluid 144Hz refresh rate. The screen boasts an impressive peak brightness of 4500 nits, ensuring optimal visibility even in bright outdoor conditions.
Despite its ultra-thin profile, TECNO has not compromised on photographic capabilities. The TECNO SPARK Slim incorporates an advanced dual rear camera system featuring twin 50MP sensors, complemented by a 13MP front-facing camera for high-quality selfies and video communications. Adding to its distinctive aesthetic, the device features an interactive light band that creates dynamic lighting effects, enhancing both form and function.
The construction of the SPARK Slim reflects TECNO’s commitment to sustainability and premium craftsmanship. The device utilizes fully recycled aluminum through an integrated die-casting process and features a stainless steel unibody design. These materials not only contribute to the phone’s luxurious tactile experience but also support its structural integrity despite the minimal thickness.
Power management represents another area where the SPARK Slim excels. The device supports 45W fast charging technology, ensuring minimal downtime for users. Internally, the smartphone is powered by an upcoming high-performance octa-core processor designed to deliver seamless operation and exceptional battery efficiency.
As an AI-driven technology brand with a presence in over 70 markets across five continents, TECNO continues to pursue innovation that resonates with consumers in emerging markets worldwide. The SPARK Slim exemplifies the company’s brand philosophy of “Stop At Nothing,” pushing boundaries in smartphone design while maintaining practical functionality.
The debut of the TECNO SPARK Slim at MWC 2025 signals a potential shift in smartphone design priorities, demonstrating that ultra-thin profiles need not come at the expense of battery capacity or performance. Industry observers and technology enthusiasts alike will be watching closely as this concept device potentially influences the next generation of mobile devices.
