At the MWC 2025 in Barcelona, Tecno is set to unveil its Tecno Spark Slim concept phone, which is creating a lot of buzz for being one of the thinnest smartphones in the world. With a 5.75mm thickness, 5,200mAh battery, and powerful features, the Tecno Spark Slim is poised to make a huge impact in the smartphone market. Let’s dive into everything we know about this innovative phone so far.
Ultra-Thin Design: Breaking the Limits
The standout feature of the Tecno Spark Slim is its ultra-thin profile. At just 5.75mm thick, it is one of the world’s thinnest smartphones. Despite its slimness, Tecno has managed to fit a 5,200mAh battery inside, a remarkable feat in smartphone design. The phone is crafted from recycled aluminum with a stainless steel frame, offering a premium look without compromising on durability.
What makes this phone truly impressive is the 4.04mm thick battery, which is a breakthrough in both battery technology and smartphone design.
Display: A Visual Delight
The Tecno Spark Slim comes with a 6.78-inch 3D curved AMOLED display that provides an immersive viewing experience. The display offers 1.5K resolution and a 144Hz refresh rate, ensuring smooth visuals for both gaming and video content. One of its key highlights is the 4,500 nits peak brightness, which guarantees visibility even in bright sunlight – perfect for outdoor use.
The AMOLED screen promises vibrant colors and deep blacks, making it a visual treat for users.
Camera: Dual 50MP Setup for Stunning Shots
For photography, the Tecno Spark Slim features a dual 50MP rear camera setup, making it capable of capturing stunning photos with vivid colors and excellent detail. Whether it’s in daylight or low-light conditions, the dual cameras are designed to deliver high-quality images.
For selfie lovers, it also comes with a 13MP front camera for crystal-clear selfies and smooth video calls. While Tecno hasn’t revealed much about its AI enhancements for photography, we can expect features like portrait mode and night mode to improve the overall camera experience.
Performance & Battery Life: Efficient and Long-Lasting
The Tecno Spark Slim is powered by an octa-core CPU, though the exact chipset is still unknown. Based on Tecno’s history, this phone is expected to perform well during daily tasks, multitasking, and even light gaming.
The phone also packs a 5,200mAh battery with 45W fast charging support, meaning you won’t have to wait long to recharge your phone. The long-lasting battery ensures that you can stay connected throughout the day without worrying about running out of juice.
Competition and Market Expectations
Though Tecno has not yet announced the price or availability of the Spark Slim, this concept phone is expected to go up against flagship devices like the Samsung Galaxy S25 Edge and the rumored iPhone 17 Slim. The phone’s thin profile and powerful features make it a strong competitor in the premium smartphone segment.
It is also likely that Tecno will make a strong market entry with a competitive price, once they finalize the phone’s specifications and mass production.
