In a smartphone world dominated by Apple and Samsung, innovation often feels incremental slightly better cameras, faster chips, or subtle design tweaks. Enter Tecno, a China-based brand known for pushing the envelope, with its latest creation: the Slim phone. This isn’t just another sleek device; it’s an ultra-thin handset that challenges what consumers expect from modern smartphones.
At IFA 2025, I held the Slim in my hands, and its feather-light frame immediately made me question why mainstream devices in the U.S. lag behind in daring design. With a striking waterfall display, surprisingly robust battery, and playful personality in its rear lights, Tecno’s Slim is a bold statement—one that forces Apple and Samsung to rethink thinness and innovation.

Tecno’s Bold Move in Smartphone Design
China-based Tecno has a knack for unconventional devices. Earlier this year, the company revealed the Phantom Ultimate G Fold, a tri-fold concept that wraps around itself in the shape of a “G.” The Tecno Slim, however, is a real product available in Asia and Europe—though U.S. buyers are still out of luck.
There are two versions:
- Spark Slim (4G) – 5.93mm thick
- Pova Slim (5G) – 5.95mm thick
Numbers alone don’t do justice to its thinness. Holding it in your hand, you realize this may be the thinnest mobile phone I’ve ever touched. The waterfall-type display, with edges sloping toward the back, feels like holding a delicate pane of glass rather than a conventional smartphone.
How It Stacks Up Against the Competition
By comparison, the Samsung Galaxy S25 Edge measures 5.8mm thick, slightly thinner on paper. But Tecno doesn’t sacrifice functionality for design. The Slim boasts:
- AMOLED display with 1.5K resolution
- 144Hz refresh rate
- 5,160mAh battery supporting 45W fast charging
The S25 Edge, meanwhile, comes with a 3,900mAh battery. Rumors about Apple’s iPhone 17 Air suggest the device may also compromise battery life to achieve an ultra-thin profile.
A Phone With Personality
Tecno promises 24–28 hours of battery life, thanks in part to a 0.3mm-thick vapor chamber to manage heat. On top of that, the Slim has a surprisingly playful design. Its rear camera cutout resembles a googly-eyed face, complete with lights that blink or wink based on your interactions—imagine Nothing’s Phone 3 with a little more charm.
Where the Slim Falls Short
Of course, every design has trade-offs. The Slim’s limitations include:
- Processing power: Spark Slim uses a Helio G200; Pova Slim features MediaTek Dimensity 6400 5G+
- Camera performance: Not comparable to flagship devices
- Software: Runs Android 15, which may delight or frustrate depending on your taste
In short, if you prioritize raw performance or photography, this isn’t the phone for you.
Availability and Pricing
Tecno confirmed the Slim will be released soon, though pricing has not yet been announced. And for U.S. buyers, the sad reality remains: interesting, ultra-thin phones with solid batteries aren’t coming stateside anytime soon.
