Report: Samsung Using New Battery Tech In Galaxy S26 With 'monster' Capacity Over 6,000 MAh

Samsung is seemingly looking to make a big battery change going into development for the Galaxy S26, switching to a silicon carbon material more OEMs are using to expand battery efficiency. The new battery type has proven to make a huge difference in overall performance, which is something most are hoping to see in Samsung’s next flagship.

Even though the Galaxy S26 has only just been released globally, reports are coming out about what the Galaxy S26 might offer. The Galaxy S25 was met with mixed thoughts, though the phone has since proven to impress in a lot of ways, thanks to One UI 7. The biggest annoyance was the seemingly stagnant spec sheet, which brings the same milliampere-hour rating over from one year ago.

That may change in 2026. A new report indicates that Samsung is planning on incorporating silicon carbon into its battery build for the Galaxy S26 (via FNNews). The new tech is said to include a “monster battery” with around 6,000 mAh or 7,000 mAh taking up the same footprint. Several known leakers have corroborated the idea of a higher capacity Galaxy S device in 2026 and going forward. That would normally be a logical conclusion, but there is a big shift in the market towards silicon carbon batteries, especially in China.

Silicon carbon batteries are more dense and pack more energy in the same amount of space compared to a lithium-ion unit. With a different graphite to silicon ratio than the batteries used in current flagships, storage capacities are larger. We’ve seen these batteries in phones like the Honor Magic 7 Pro, which adds a silicon carbon battery to the mix. The upgrade proves to be worthwhile if done properly.

Samsung hasn’t exactly impressed in the battery category lately. The Galaxy S24 series came with a decent mAh count, but it was nothing incredible. This year, it seems the story is the same and the Galaxy S25 series carries those same numbers over with little improvement. If the next generation of Galaxy S devices takes on a higher mAh count with better battery efficiency due to silicon carbon cells, it could be a redeeming point.
