Samsung s26 ultra: the slimmest camera flagship arrives

Samsung has quietly achieved a significant victory in the increasingly competitive smartphone landscape: crafting the slimmest camera-centric flagship currently available. The Galaxy S26 Ultra, clocking in at a mere 7.9mm, is defying expectations and setting a new standard for industrial design amongst devices prioritizing photographic capabilities.

A thin profile amidst bulky rivals

While recent Galaxy S Ultra models have faced criticism for not boasting the absolute largest sensors or widest apertures, their versatility in skilled hands remains undeniable. The S26 Ultra continues this trend, leaning on software optimization to deliver impressive image quality. But the real differentiator isn't the camera itself; it's the remarkably slim profile that sets it apart from the pack. Consider the competition: Xiaomi's 17 Ultra and Oppo's Find X9 Ultra both exceed 8mm, while the iPhone 17 Pro Max weighs in at 8.75mm (excluding its substantial camera island). The S26 Ultra's svelte figure is a clear win for those who value aesthetics and pocketability.

The choice of prioritizing thinness is a somewhat surprising one, particularly given that ultra-thin designs like last year's Galaxy S25 Edge proved commercially unsuccessful. Yet, Samsung's ability to shave millimeters off the chassis while maintaining performance signals a commitment to design innovation.

The key to this feat? It appears Samsung has avoided incorporating larger sensors or higher-capacity batteries, a trade-off that could ultimately limit longevity. Currently, the Ultra relies on a 5,000 mAh battery – a figure that hasn't changed in seven years. However, the future could hold a solution: silicon-carbon battery technology.

Si-C battery cells promise a significantly higher energy density than traditional lithium-ion, potentially allowing a 6,000 mAh cell to occupy the same physical footprint as the current battery. This would enable Samsung to boost endurance without sacrificing the Galaxy S26 Ultra's enviable slimness. The prospect of a thinner, longer-lasting flagship is a tantalizing one, and a potential game-changer for Samsung’s Ultra line.

The market clearly values a slim profile – evidenced by the recent vote among tech enthusiasts, where most prioritized a phone under 8mm. But the pursuit of thinner devices shouldn’t come at the expense of essential features. Samsung’s success with the S26 Ultra demonstrates that it's possible to achieve both, paving the way for a new generation of elegantly designed, powerful smartphones.
