Samsung has unveiled the new generation of its foldable phones, which this time stand out for adopting silicon-carbon (SiC) battery technology for the first time in its smartphones, after years of using traditional lithium batteries.

This move follows the adoption of this technology by a number of Chinese brands starting in 2023.

Silicon-carbon batteries offer higher energy density compared to lithium-ion batteries, allowing for larger capacities within the same dimensions, thus enabling companies to equip their phones with higher-capacity batteries without increasing size or weight.

Samsung has finally responded to user demands, especially regarding its foldable phone series, which previously suffered from lower battery capacities than competitors.

The company has launched, within its new Galaxy Z Fold 8 Ultra, Z Fold 8, and Z Flip 8 series, its first phones equipped with these batteries.

Thanks to this technology, the Galaxy Z Fold 8 Ultra gets a 5,000 mAh battery, while the Galaxy Z Fold 8 is equipped with a 4,800 mAh battery, a notable increase from the 4,400 mAh capacity of the previous generation.

As for the Galaxy Z Flip 8, despite adopting the same technology, it retains the same battery capacity of 4,300 mAh, while reducing the device thickness to make it slimmer than the previous version.

This change is Samsung's biggest battery update in its foldable phones in years, and may pave the way for wider adoption of silicon-carbon batteries across the company's other phones, including the Galaxy S, Galaxy A, Galaxy M, and Galaxy F series in the future.
