Samsung Galaxy S27 Ultra Could Launch With Silicon-Carbon Battery Upgrade: Report
Samsung is reportedly testing silicon-carbon battery technology for future flagship smartphones, even as the Galaxy S26 Ultra retains a 5,000mAh battery. A new report claims the company is evaluating high-capacity cells up to 20,000mAh using new stacking methods. While the technology allows higher energy density without increasing thickness, current prototypes fall short of durability targets. Samsung is taking a cautious approach due to safety standards, but the Galaxy S27 Ultra could become the first model to adopt the upgrade.
