TECNO SPARK Slim Sets a New Record with Its Ultra-Thin 5.75mm Profile

TECNO has introduced the SPARK Slim, a concept phone that is redefining ultra-thin smartphone design. Unveiled at MWC 2025, this device holds the title of the world’s thinnest smartphone at just 5.75mm thick.

Sleek and Ultra-Thin Design

The TECNO SPARK Slim lives up to its name with a stunningly thin 5.75mm profile and only weighs 148g making it one of the most lightweight smartphones today. Despite its slim frame, the phone is built with fully recycled aluminum and a stainless steel frame, ensuring durability while maintaining a premium look.

AMOLED Display with Ultra-Bright Visuals

TECNO has equipped the SPARK Slim with a 6.78-inch 3D curved AMOLED display that offers 1.5K resolution for crisp and clear visuals. The 144Hz refresh rate ensures ultra-smooth scrolling and animations. Even in direct sunlight, the 4,500-nit peak brightness guarantees excellent visibility, making it one of the brightest smartphone screens available today.

Long-Lasting Battery with Fast Charging

Despite its ultra-thin body, TECNO has packed the SPARK Slim with a 5,200mAh battery, providing all-day power. When you do need to top up, the 45W fast charging support ensures you’re back to full power in no time.

Sharp Cameras

Photography enthusiasts will appreciate the dual 50MP rear cameras, which capture detailed and vibrant photos in various lighting conditions. Whether it’s daylight shots or night photography, the SPARK Slim is designed to deliver high-quality images. The 13MP front-facing camera ensures clear selfies and smooth video calls, making it a great choice for content creators and social media users.

A Bold Step in Smartphone Innovation

The TECNO SPARK Slim is more than just a concept phone—it’s a glimpse into the future of ultra-thin smartphone design without sacrificing performance. With its sleek body, immersive display, powerful internals, long battery life, and premium build, this phone is perfect for those who want style and functionality in one device.
