At MWC 2025, Tecno unveiled its Spark Slim smartphone. While the company calls it a concept device (read: prototype), it is reportedly preparing for a "staggered launch" later this year. Regardless, after brief hands-on time with the phone, I can confidently say this is how thin phones should be done.

The Tecno Spark Slim is an ultra-thin, high-end Android phone that looks a lot like the rumored iPhone 17 Air - here's what it has to offer.

The superthin phone also features a 5,200-mAh battery, which means that if the device were ever to make it to market, it wouldn't have to compromise on functionality.
