Samsung is preparing to increase the battery capacity in its upcoming Galaxy S26 series smartphones. According to Korean media outlet FN News, the company is likely to adopt silicon-carbon technology for this series, which could boost the phone's battery capacity to as much as 7,000mAh.
This new technology replaces graphite with silicon in the battery’s cathode material, significantly enhancing energy storage capacity. However, Samsung had previously been hesitant to use this technology due to concerns over high production costs. As Chinese brands like Xiaomi, Vivo, and OnePlus have already implemented this technology in their flagship smartphones, Samsung now aims to stay competitive.
That said, Samsung plans to be cautious in adopting silicon-carbon battery technology. Since it manufactures a significantly higher number of units compared to its Chinese competitors, any potential issues could have widespread consequences. This is one reason the company has maintained 25W and 45W charging speeds for years.
The recently launched Galaxy S25 Ultra features a 5,000mAh battery with 45W charging, similar to the five-year-old Galaxy S20 Ultra. Likewise, the Galaxy S25 has a 4,000mAh battery with 25W charging, the same as the 2020 model. However, the Galaxy S25 Plus has received a slight battery upgrade. Though considered the least attractive among the three flagship models, it still benefits from improved battery capacity.
