Smartphone brands seem to be focusing on making devices thinner in 2025. Samsung recently revealed the Galaxy S25 Edge with a slim design, and Apple is rumored to be launching the iPhone 17 Air later this year. Now, Tecno is joining the trend with the Spark Slim, a concept phone set to be showcased at MWC 2025.
The Spark Slim measures just 5.75mm thick, making it the world’s slimmest phone, according to Tecno. Despite its slimness, it packs a 5,200mAh battery, which is even bigger than what you get on the Galaxy S25 Ultra, which measures 8.2mm.
The phone has a 6.78-inch curved AMOLED display with a 1.5K resolution and a 144Hz refresh rate. Tecno also claims the screen has a peak brightness of 4,500 nits which should be plenty for outdoor visibility.
Many slim smartphones trade battery life for design, but Tecno says the Spark Slim avoids this issue with a high-density battery and 45W fast charging. Under the hood, it runs on an octa-core processor—though Tecno hasn’t revealed exactly which chip it’s using.
On the back, the Spark Slim sports a dual 50MP camera system, while the front gets a 13MP selfie shooter. Tecno has also added a light band around the rear cameras for a bit of extra flair.
The company says it prioritized both durability and weight, using recycled aluminum and a stainless steel unibody. And design-wise, the Spark Slim is definitely eye-catching—especially its camera module.
It features a horizontal, pill-shaped layout, but instead of the usual centered sensors, the two cameras sit at the far left and right. The look is somewhat reminiscent of the rumored iPhone 17 Air renders that have been making the rounds.
Tecno will display the phone at its MWC 2025 booth. Hopefully, we will be there to give you more details on it.
