Tecno is preparing to unveil its Tecno Spark Slim concept phone at the Mobile World Congress (MWC) 2025 in Barcelona next week. The company claims that this smartphone will set a new record as the world’s thinnest phone, measuring just 5.75mm thick while still packing a 5,200mAh battery. With a sleek design and high-end specifications, the Tecno Spark Slim is expected to make a significant impact at the event.
Design and Display
The Tecno Spark Slim is designed to be ultra-thin while maintaining impressive performance. It features a 6.78-inch 3D curved AMOLED display with a resolution of 1.5K and a smooth 144Hz refresh rate. The display is also exceptionally bright, reaching a peak brightness of 4,500 nits, ensuring excellent visibility even under direct sunlight.
The phone is crafted from fully recycled aluminum, using an integrated die-casting process. It also incorporates a stainless steel frame, giving it a premium and durable feel.
Camera and Performance
Tecno has confirmed that the Spark Slim will come equipped with a dual rear camera setup, featuring a 50-megapixel primary sensor alongside another 50-megapixel sensor. For selfies and video calls, the phone sports a 13-megapixel front camera.
While the chipset has not been officially revealed, the smartphone is confirmed to be powered by an octa-core CPU. This suggests it will offer a balance of performance and efficiency, making it a capable device for everyday use.
Battery and Charging
Despite its ultra-thin profile, the Tecno Spark Slim houses a 5,200mAh battery, which is a major achievement given the device’s slim form factor. The battery itself measures just 4.04mm in thickness. Additionally, the phone supports 45W fast charging, allowing users to quickly top up the battery when needed.
Expected Launch
Tecno has not yet announced the pricing and availability details of the Spark Slim. Since the company is referring to it as a concept smartphone, its final market release may depend on further developments revealed at MWC 2025, which takes place from March 3 to March 6 in Barcelona, Spain.
If the Spark Slim makes it to the consumer market, it will likely compete with upcoming slim flagship devices such as the Samsung Galaxy S25 Edge and the rumored iPhone 17 Slim (or iPhone 17 Air).
With its ultra-thin design, high-resolution display, and impressive battery capacity, the Tecno Spark Slim could be a game-changer in the smartphone industry. More details are expected to emerge during MWC 2025.
