The thinness of the smarpthone begins to be an issue. We don’t know why, but it is. Samsung has as your family’s star Samsung Galaxy S25 A mysterious Galaxy S25 Edge Ultradelgado. Oppo has obsessed with this data to improve the design of your Find N5and the strongest rumor on mobile technology by 2025 is the next iPhone 17 Aira model that will supposedly stand out for its data of thinness.
Manufacturing a specially thin mobile usually comes from the hand of a usual problem: the battery is usually quite just. The Chinese manufacturer Tecno has shown that this does not have to be so and that, technically, it is possible to manufacture an extremely thin phone with a level battery.
Tecno Spark Slim. Do not look for this phone on the Tecno website, because it is not on sale. The Spark Slim is the thinnest mobile in the world (at least, right now), with a thickness of only 5.75mm. It is almost half of what the most top phones usually have (which are around 8mm) and, all this, without sacrificing battery.
Its battery is 5,200mah, a battery even larger than we find on much thicker phones. In addition, the weight is also a record: Tecno has been achieved by a figure of only 140 grams.
We do not know its processor, although the company tells us that it has not yet been presented. The screen is of no less than 6.78 inches, amoled and with a 4,500 nits peak shine, so we are not facing a reduced SPECS phone.
The key… and the sacrifices. Tecno has not relieved images of the internal construction of his Spark Slim, but it does give a curious fact: his battery has a thickness of only 4mm. A record has been achieved, introducing a much larger battery than usual is an extremely thin phone.
Although we have not been able to try it thoroughly, achieving something like this always has costs. Otherwise, all manufacturers would follow this path. If we look at the camera module, it can be seen that the sensors seem quite small. It is inevitable: if the vast majority of the body is drums, there is not too much space for large sensors.
To achieve this thickness, it is also difficult to add elements such as steam cameras, large speakers, or other elements that enrich hardware. Despite this, it seems clear that any user needs: a great battery, a processor, and a couple of cameras.
An inevitable trend. Achieving extreme thinness is a trend. The great manufacturers (OPPO, Samsung and expected Apple) begin to a race whose purpose we do not know, and whose future sales will reveal the unknown: whether to fight for thinness really revives demand, or if it is a race without too much sense.
