TECNO Spark Slim Review — The World’s Slimmest 3D Curved Phone! Worth It or Overhyped?

The TECNO Spark Slim is officially the world’s slimmest 3D curved smartphone — but is that enough to make it one of the best budget phones under ₦300,000? In this full review, I break down the design, display, performance, cameras, battery life, and the “K-leg” areas you need to know before buying it. While other smartphone makers have been recycling designs for years, TECNO actually tried something refreshingly different with the Spark Slim — a super lightweight body, premium 1.5K AMOLED display, 144Hz refresh rate, bright 4,500-nit screen, and a surprisingly strong battery inside a very thin frame. But it’s not perfect. The camera has its limits, the speakers aren’t the loudest, and there’s no microSD card slot. So is this phone really worth your money? Let’s find out. In this video, I also talk about the performance of the Helio G200 chipset, the new AI features like AI Eraser, Ella Assistant, Dual System, FreeLink, and more. I also show sample photos, camera performance in daylight and low light, and share my full charging test results (0–100% in 1 hour 2 minutes). If you’re considering buying the TECNO Spark Slim, this video will tell you everything you need to know.
