Samsung may finally address one of its smartphones’ biggest weaknesses: battery life. According to South Korean publication FN News, the company is exploring integrating next-generation silicon carbide batteries into its upcoming Galaxy S26 series flagships. And it appears Samsung is aiming high.
Industry insiders suggest the Galaxy S26 series could boast batteries with capacities between 6,000 and 7,000 mAh. This is a significant jump from the 5,000 mAh battery in the current Galaxy S25 Ultra. Competitors, however, already offer batteries up to 7,000 mAh at nearly half the price of Samsung’s flagship models.
Samsung is reportedly interested in leveraging the benefits of silicon carbide battery technology. This technology offers higher energy density, enabling larger battery capacities in smaller devices. The Red Magic 10 Pro, for example, is roughly the same size as the Galaxy S25 Ultra, but packs a 7,000 mAh battery with 100W fast charging.

However, Samsung is mindful of the potential impact on battery longevity. To address this, the company is reportedly experimenting with different materials and adjusting the silicon concentration in the battery anode to achieve a denser, longer-lasting battery.
Another advantage of silicon carbide batteries is their compatibility with fast charging. Brands like OnePlus and Honor have already integrated large batteries into their flagships while offering wired charging speeds exceeding 80W.
In contrast, Samsung’s current phones max out at 45W wired charging and significantly slower wireless charging. The OnePlus 13, for instance, supports 50W wireless charging, while Samsung’s top-of-the-line phones are limited to 15W.

While this report is promising, it doesn’t guarantee the Galaxy S26 series will definitively solve Samsung’s battery shortcomings. The transition could take another year or two. Nevertheless, it’s encouraging to see Samsung prioritizing practical innovations and potentially closing the gap with its competitors.
Samsung’s mobile division seems to be on the right track. According to Counterpoint Research, the Samsung Galaxy S24 Ultra marked the first time since 2018 that a Samsung Galaxy device has ranked among the top ten best-selling smartphones globally each year.
