Tecno’s latest Spark Slim is touted as the “world’s thinnest smartphone.” At just 5.75mm thick, this concept phone is about cutting down the bulk without cutting corners. Despite its ultra-slim frame, Tecno squeezed in a 5200mAh battery, somehow packing all that juice into a 4.04mm design, as per the brand.
Up front, there’s a 6.78-inch 3D curved AMOLED display with a 144Hz refresh rate, 1.5K resolution, and an eye-searing 4500 nits of peak brightness—because who doesn’t love a screen that shines like a mini sun?

Tecno says the Spark Slim has a "high-performance octa-core chip" without revealing the details. It sports a 50MP dual-camera setup on the back and a 13MP selfie shooter up front. And, the phone is crafted from recycled aluminium with a stainless steel frame.
