Samsung confirms again that it's working on silicon carbon batteries

The world’s two biggest smartphone brands, Apple and Samsung, use lithium-ion batteries in their smartphones. Chinese smartphone brands, on the other hand, have been adopting a newer battery technology, silicon-carbon, for the past few years. Thanks to its higher energy density, silicon-carbon technology allows manufacturers to offer batteries with significantly higher capacities without increasing the device size.

Last year, Samsung revealed that it was also developing silicon-carbon batteries and intended to use them in its smartphones in the future. While people were expecting to see them on the Galaxy S26 series, that didn't happen. Now, the tech giant has once again confirmed that it is working on silicon-carbon batteries, and suggested that the technology hasn't matured enough to be safely used for smartphones.

During the Galaxy S26 press briefing, which we were a part of, Samsung's Executive Vice President, Jeong Seung Moon, said that the brand is actively developing silicon-carbon batteries. He added that the brand will begin using them in its smartphones only once they pass rigorous internal testing and once the company is confident that the technology meaningfully improves the overall user experience.

In other words, Samsung suggests that silicon-carbon batteries have yet to meet its testing standards and that, at present, they do not deliver a clear customer-experience advantage. While the former claim may well be true, considering the brand had set high standards after the Galaxy Note 7 battery fiasco, we’re not entirely convinced by the latter, especially after seeing the battery life of new Chinese phones.
