Samsung is reportedly working on silicon-carbon (Si/C) battery technology for its upcoming Galaxy S26 Ultra. According to a new report, the device could feature a 7,000mAh battery, surpassing most current flagship smartphones. This article will discuss everything about all the rumors regarding the upcoming Samsung Galaxy S26 Ultra, including their rumors.

Samsung Galaxy S26 Ultra Rumors

Samsung’s Silicon-Carbon Battery Plans

Samsung has been rumored to be developing silicon-carbon batteries to improve power efficiency while maintaining a slim design. A new report from South Korean publication FNNews suggests that the Galaxy S26 Ultra might be the first Samsung device to feature this battery technology.

Comparison with Other Smartphones

Chinese smartphone manufacturers have already started adopting Si/C batteries. The Nubia Red Magic 10 Pro has a 7,050mAh battery, and the upcoming Redmi Turbo 4 Pro is expected to feature a 7,500mAh unit. While Samsung does not directly compete with Chinese brands, adopting this new battery technology could influence Apple and other manufacturers to follow.

Battery Life and Charging

Samsung’s One UI 7 already provides optimized battery performance, even with similar battery sizes as previous models. If the silicon-carbon battery rumor is true, the Galaxy S26 Ultra could see a significant improvement in battery life.

Additionally, the Galaxy S26 series is expected to support 65W fast charging, reducing charging times despite the larger battery capacity.
