2025 will be characterized by the return of fine mobiles with the arrival of the Samsung Galaxy S25 Edge and the rumored iPhone 17 Air. It is easy to forget it, but there was a time when manufacturers were obsessed with creating increasingly fine devices, even sacrificing fundamental aspects such as performance or battery.
Fortunately, in recent years, companies have preferred to bet on more practical and powerful mobiles, without giving such importance to having 0.1 mm more or less. However, technology is already reaching a point where it is possible to recover that obsession with thickness without making so many technical sacrificesand from there the next Samsung and Apple releases. But a brand is going to advance, and it is one that the reader probably did not expect: Tecno.
Although Tecno is little known in Spain, it is actually one of those brands that is always present in all market trends, sometimes even surpassing established names.
That is the case of the new Spark Slim, which is presented as “the finest device with a 5,200 mAh battery”, with A thickness of only 5.75 mmthat for practical purposes it is the most thin new mobile in the market.
The company has had to make that clarification because, in reality, the Spark Slim is not the finest mobile in the history of the sector, or by far; As we have said, in the past many brands forgot to make usable mobiles in their mission for reducing the thickness, lowering 5 mm. Therefore, Tecno has wanted Highlight the battery capacity, of 5,200 mAhto make it clear that you are not making meaningless sacrifices just to obtain this achievement.

In fact, apart from the thickness, this seems to be a fairly conventional mobile. Tecno Spark Slim is based on a 6.78 -inch screen that curves on the sides, with a 1.5K resolution and a 144 Hz soda frequency and a maximum brightness of 4,500 nits. Tecno has even found room to put Two 50 MPX camerasalthough in the photos the bulge they produce in the rear is noticeable.
The only aspect that has not yet been revealed to the Spark Slim is the processor, with techno, stating only what it is an eight -nuclei model that is yet to come; Therefore, it is possible that it is a model that has not yet been presented and that will probably highlight for its low consumption and energy efficiency, which is what will have allowed this low thickness.
However, we should not expect much power of the Spark Slim, especially because Tecno is a brand aimed at low and half -ranges. The company is expected to offer more details in the MWC.
