Highlights
- The Samsung Galaxy S26 is expected to feature a battery upgrade with silicon carbon technology.
- It will potentially result in achieving a battery capacity of 6,000mAh or even 7,000mAh.
- Silicon carbon batteries are more energy-dense than traditional lithium-ion batteries.
- Reports suggest that the Galaxy S26 with its new battery technology could debut in 2026.
Even though the Galaxy S25 has just launched, reports about its successor are already surfacing online. It appears Samsung is making a major battery upgrade for the Galaxy S26. Here’s everything we know about this update so far.
Battery Upgrade for the Galaxy S26
The Galaxy S25 received mixed reactions mainly because its battery specs remained unchanged from the previous year. However, a new report from the Korean News website FNNews suggests that Samsung is planning a big leap in battery technology for the Galaxy S26, which could debut in 2026.
According to the report, Samsung is working on introducing silicon carbon technology to improve efficiency and capacity. This shift could result in a battery of 6,000mAh or even 7,000mAh while maintaining the same physical size.
Silicon carbon batteries are more energy-dense than traditional lithium-ion batteries. By adjusting the graphite-to-silicon ratio, they can store more power without increasing size. We’ve already seen this technology in action with phones like the Honor Magic 7 Pro and if done right, it could be a game-changer for Samsung.
Popular tipster @Jukanlosreve also shared the FNNews piece on his X (formerly Twitter) handle, which many tech enthusiasts are assuming to be a confirmation.
The FNNews report also highlights (translated via Google Translate), “Recently, Chinese smartphone manufacturers are competing to release smartphones equipped with silicon carbon batteries. A silicon carbon battery made by Chinese manufacturer CATL was used. Smartphones recently released by Chinese manufacturers such as Xiaomi, Vivo, and ZTE have battery capacities of 6000~7000mAh and wired charging speeds of 80~100W. Chinese IT tipster Digital Chat Station predicted, “This year, many flagship (top-end) smartphones will support 7,000 mAh and 100 W or more,” and “the battery capacity of mid-range smartphones will increase to 7,500 to 8,000 mAh.”
Samsung hasn’t exactly made any major innovations in battery life lately. The Galaxy S24 series had decent battery capacities but nothing groundbreaking. The Galaxy S25 followed the same trend, carrying over similar battery specs. However, if the Galaxy S26 comes with a significantly larger and more efficient battery, it could finally put Samsung back ahead in battery performance.
As of now, all the updates are part of speculations and nothing has been confirmed including the claim in multiple leaks that suggest a higher-capacity Galaxy S device is coming in 2026.
