TL;DR

Samsung has confirmed that the Galaxy Z Flip 8, Galaxy Z Fold 8, and Galaxy Z Fold 8 Ultra all have silicon-carbon batteries.

These are therefore the first Galaxy phones with silicon-carbon battery technology.

Samsung didn’t disclose more details about the tech but said you should expect battery health that’s “consistent” with previous products.

Smartphones with silicon-carbon batteries have been around since 2024, when HONOR debuted the tech. We’ve since seen the likes of OnePlus, OPPO, Xiaomi, and others all embrace this battery technology. Samsung has been one of the few high-profile holdouts, but that changes today.

Samsung confirmed during a media briefing and a media roundtable that the Galaxy Z Flip 8 , Galaxy Z Fold 8 , and Galaxy Z Fold 8 Ultra all have silicon-carbon batteries. That means these are the first Galaxy phones with this technology. Furthermore, the Galaxy Watch Ultra 2 also benefits from a silicon-carbon battery, making it quite possibly the first Samsung watch with this tech.
