TECNO has officially launched its groundbreaking TECNO Slim series at IFA 2025, setting a new milestone in smartphone design and performance. The lineup includes the TECNO SPARK Slim (4G) with a 5.93mm profile and the TECNO POVA Slim (5G) at 5.95mm, both ranking among the world’s thinnest smartphones with 3D-curved AMOLED displays. Despite their record-breaking slimness, the models pack a 5160mAh battery with 45W fast charging, along with military-grade durability certification, balancing elegance with resilience.
Engineering Breakthrough in Structural Innovation
At under 6mm, TECNO Slim pushes smartphone miniaturization further than ever before. The company has re-engineered eight core modules, including the battery, speaker, SIM slot, and charging connector, achieving unmatched compactness. The device also introduces a 0.45mm single-tab Type-C connector inspired by foldables, reducing bulk. Combined with TECNO’s Honeycomb stacking technology, the phone gains 12% more internal space efficiency, proving that ultra-thin does not mean underpowered.
Strength Meets Slimness
To maintain strength within its ultra-slim body, TECNO uses a 0.36mm aerospace-grade fiberglass back cover that is 300% stronger and 200% tougher than standard composite plates. On the front, Corning Gorilla Glass 7i adds protection against scratches and drops, while IP64-rated water and dust resistance further enhances reliability. Certified Military-Grade Shock Resistant, the TECNO Slim offers toughness within a feather-light form.
Power and Endurance in a Slim Package
Battery life, often a weak point in slim devices, has been revolutionized with TECNO Slim. The 5160mAh high-density lithium cobalt oxide battery achieves extended longevity while staying just 4.04mm thick. Even after 2,000 charge cycles, it retains 80% capacity, delivering over five years of reliable use. Coupled with 45W fast charging, users enjoy up to 28 hours of usage on a single charge. An advanced cooling system with vapor chamber and graphite layers ensures smooth performance under heavy loads.
Advanced Performance and Immersive Displays
The TECNO Slim offers distinct performance solutions: the 4G version with Helio G200 and the 5G model powered by MediaTek Dimensity 6400 5G+, ensuring efficiency and next-gen connectivity. Both feature curved AMOLED displays with 1.5K resolution, 144Hz refresh rate, and up to 4,500 nits peak brightness, delivering sharp, vibrant visuals for gaming, streaming, and outdoor use.
Smarter Interactions and AI Features
The phone introduces a Mood Light design with two circular “eyes” on the back that express emotions with light animations during calls, charging, or notifications. It also comes with TECNO AI features, including real-time translation, AI-powered writing tools, Circle-to-Search, and the Ella AI assistant. Additional features such as multifunctional NFC, HiOS based on Android 15, and FreeLink connectivity enhance everyday usability.
Pioneering a New Era for Ultra-Slim Phones
TECNO Slim is more than a smartphone; it is a redefinition of what slim technology can achieve. Within just half a year of development, TECNO has merged slim design, durability, and class-leading performance, creating a device tailored for both global and emerging markets. By delivering compromise-free design with powerful performance, TECNO Slim sets a new benchmark in the evolution of smartphones, proving that thinner can indeed be stronger.
