Tecno Unveils Spark Slim is the World’s Thinnest Smartphone

Tecno has unveiled what it claims is the world’s thinnest smartphone, the Spark Slim, measuring just 5.75 mm thick and incorporating two 50 MP cameras and a robust 5,200 mAh battery.

Although attention-grabbing, this device is currently only a concept, and there is no information regarding when (or if) it will reach the market in its present form. Demo units will be on display at the upcoming Mobile World Congress, but it seems unlikely that consumers will see a commercial launch anytime soon.

The Spark Slim carries a 6.78-inch AMOLED screen with curved edges, offering 1224p resolution and supporting a 144 Hz refresh rate. Tecno claims it achieves a peak brightness of 4,500 nits and has a 13 MP front-facing camera. The phone’s 4.04 mm thick battery supports 45W fast charging, and while the camera bump adds a minor bit of bulk, this design still stays exceptionally streamlined.

Tecno has not revealed the Spark Slim’s chipset, mentioning only that it features an octa-core CPU. A flagship-class platform seems unlikely, as advanced cooling systems typically needed for such performance are larger than the Spark Slim’s compact frame would allow.

Visitors to MWC in Barcelona can see the Spark Slim in person. The plan is for us to check it out there and get a feel for how Tecno’s ultra-slim device handles, especially given its concept status. Ultimately, its cutting-edge dimensions and features may signal new possibilities for smartphone design, but whether the Spark Slim will ever appear on store shelves remains in question.
