Samsung is attempting to construct curiosity within the Galaxy S25 Edge by showcasing it behind glass enclosures at tech conferences forward of its deliberate launch someday in Q2 2025, however Chinese language producer Tecno managed to steal its thunder at MWC 2025 with the Spark Slim, at the moment the thinnest telephone on the earth.
The Spark Slim has a thickness of simply 5.75mm, making it significantly thinner than Samsung’s upcoming ultra-thin telephone. However the place it really stands out is the battery; Tecno in some way managed to fit in a large 5200mAh battery into the telephone, and that is simply wild.

I managed to get my fingers on the gadget on the MWC present flooring, and the glossy profile is a particular differentiator; it makes all different gadgets look bloated — notably the Xiaomi 15 Extremely that I used to take these pictures.

The distinctive design characteristic is the digital camera island on the again, and the broad digital camera bar evokes reminiscences of Motorola’s Droid gadgets of yesteryear. I actually just like the design of the digital camera housing, and whereas it protrudes barely from the chassis, it is not all that noticeable. There’s an LED gentle ring round every module, and a horizontal bar that runs alongside the width of the digital camera housing, and it is simply plain cool.
In contrast to most telephones at the moment, the Spark Slim has dual-curved edges on both aspect of the display, and it has a curved sides the place the again meets the mid-frame. This allowed Tecno to cut back the thickness much more, and whereas there is not a lot to carry on to on the sides — it measures 5.75mm, in spite of everything — it wasn’t uncomfortable to carry.
If something, the plastic again and curved design help in usability, and whereas I used loads of ultra-thin telephones up to now, the Spark Slim is notable due to its sheer battery dimension. It has a particular benefit over the Galaxy S25 Edge in that regard, and once more, it is in some way thinner than Samsung’s gadget.
The Spark Slim has a 6.78-inch AMOLED that goes as much as 144Hz, and there are two 50MP cameras on the again and a 13MP digital camera positioned up entrance. Tecno did not reveal the internals, solely stating that it’s powered by an octa-core platform. The interface felt fluid within the 10 minutes I used the gadget, however then once more, it was a demo unit and did not have something put in.
At this level, there isn’t any point out of when (or if) the Spark Slim will make its debut. Whereas it’s a outstanding technical showcase, it is not clear at this level if Tecno will put the gadget into manufacturing, or if it may well achieve this at scale whereas nonetheless retaining the ultra-thin design and the 5200mAh battery. Nonetheless, the Spark Slim is proof that it’s potential to create a glossy telephone with an enormous battery, and I need Tecno to launch this gadget in some unspecified time in the future — we’d like higher options to the Galaxy S25 Edge.
