The Galaxy S25 Edge simply bought contemporary super-thin telephone competitors

If you happen to’ve been keeping track of the smartphone world these days, you’ve in all probability seen that “skinny is in.” Samsung has already confirmed the existence of its Galaxy S25 Edge, Apple is rumored to be launching an iPhone 17 “Air,” and almost each foldable telephone is attempting to shave off further millimeters. Nevertheless it seems thinness isn’t only for premium flagships. TECNO, recognized for its budget-friendly gadgets, is throwing its hat into the ring with the TECNO Spark Slim, set to debut at MWC 2025.

The corporate is touting the system because the “slimmest system with a 5,200mAh-plus battery.” If you happen to’re questioning why it doesn’t simply name it the thinnest telephone ever, it’s as a result of it isn’t. We’ve seen sub-5mm telephones from OPPO and vivo a decade in the past, however these gadgets packed a lot smaller batteries in step with the tendencies of that point. TECNO’s declare particularly ties its slimness to battery capability, which is a notable distinction.

Nonetheless, a telephone measuring simply 5.75mm thick is a formidable engineering feat, particularly contemplating the rumored ~6mm thickness of the Galaxy S25 Edge. What’s much more placing is that TECNO has managed to suit a 5,200mAh battery into this slim body, whereas Samsung’s upcoming slim flagship is reportedly sticking to a a lot smaller 4,000mAh battery.

One of many greatest developments in smartphone batteries not too long ago has been the adoption of silicon-carbon battery know-how, which permits for higher vitality density in smaller sizes. The OnePlus 13, for instance, packed an unlimited 6,000mAh battery whereas nonetheless sustaining a modern profile. Whereas TECNO hasn’t explicitly confirmed if the Spark Slim is utilizing silicon-carbon tech, it does say the telephone has a “4.04mm thick, high-density battery.”

The Spark Slim is crafted from absolutely recycled aluminum utilizing an built-in die-casting course of and options a chrome steel unibody design. For these of us who miss the times of metal-bodied telephones (HTC followers, unite!), we will solely hope that is the start of a comeback. In fact, given its steel again, it’s unlikely to help wi-fi charging (though technically, that’s not not possible). For what it’s price, the telephone does help superfast 45W wired charging.

An enormous a part of making a skinny telephone look even thinner comes all the way down to the aspect body, and TECNO has gone with a curved show that slims down the sides for a good sleeker look. The 6.78-inch AMOLED panel boasts a 1.5K decision, a 144Hz refresh fee, and a peak brightness of 4,500 nits. On the digital camera entrance, the system incorporates a 50MP+50MP twin rear digital camera setup and a 13MP front-facing digital camera.

TECNO hasn’t revealed the precise chipset powering the Spark Slim, solely referring to it as an “upcoming high-performance octa-core chip.” Nevertheless, for the reason that Spark lineup sometimes falls within the price range to mid-range class, it’s protected to imagine this received’t be a flagship processor.

For now, TECNO hasn’t shared pricing or availability particulars for the Spark Slim. In reality, it’s unclear if the corporate plans to launch it as a industrial product in any respect, as TECNO’s press launch refers to it as a “idea smartphone.”

As for me, I’ll admit I’m much less involved in regards to the thinness numbers and extra excited in regards to the shift towards high-energy-density batteries. If this development continues, we would lastly attain a degree the place multi-day battery life turns into the norm for smartphones. Certain, international manufacturers like Samsung and Google would possibly take their candy time adopting such consumer-friendly tech, however for now, it’s refreshing to see corporations like TECNO pushing the envelope.
