How skinny can a smartphone actually get?
In case you ask Samsung, it might probably go as little as 6.4mm – that’s how thick its upcoming Galaxy S25 Edge can be, making it the slimmest telephone within the firm’s 2025 lineup.
However that’s clearly not the restrict so far as telephones can go, and Tecno has confirmed it. The Chinese language firm’s new Spark Slim is an unimaginable 5.75mm, making it the world’s thinnest telephone to this point.
I’ve had the chance to attempt it at MWC 2025 in Barcelona, and it’s an extremely spectacular feat of engineering. It genuinely feels such as you’re holding one thing from the longer term.

Nonetheless, Tecno needs to emphasize that that is only a idea. The corporate has no plans to carry the Spark Slim to the market, even in its native China.
And it’s hardly stunning, as there are two key issues that I can see with this ultra-slim design.
The primary is sturdiness – the Spark Slim doesn’t have the sturdy really feel you get from thicker and heavier telephones, and it felt a bit flimsy in my hand. If I by chance sat on it or dropped it on the pavement, I’d be nervous if it may survive.
Overheating can also be a serious concern. Tecno has supposedly managed to squeeze a 5200mAh battery into the Spark Slim, however that certainly leaves no room for a correct cooling system.
In its present kind, I’d be reluctant to make use of the telephone for any demanding duties, however even utilizing it whereas charging would really feel like a threat.
Nonetheless, neither of these points are a criticism of Tecno. Even in idea kind, the corporate has proven that an ultra-slim machine is feasible, paving the best way for the same telephone to be launched sooner or later.
For its need to push the boundaries, the Tecno Spark Slim is deserving of a spot in Tech Advisor’s Better of MWC 2025 Awards.
