Samsung might level up its battery tech game, but not how we hoped

What many were really hoping for, though, was the arrival of silicon-carbon batteries. This advanced tech has already shown up in devices like the OnePlus 13T, which packs over 6,200 mAh into a surprisingly slim body. Similarly, the Oppo Find N5 uses silicon-carbon to power thin foldables with massive battery capacities. In contrast, Samsung’s latest models — including the recently launched Galaxy S25 Edge — continue to rely on traditional lithium-ion batteries, often resulting in smaller capacities and slower improvements across generations.

The choice to go with SUS CAN over silicon-carbon, at least for now, suggests Samsung is opting for an incremental step rather than a leap forward. Still, any boost to battery performance would be welcome news, especially for users of foldables and power users frustrated by short runtimes.

There’s no timeline yet for when SUS CAN batteries will start appearing in Galaxy smartphones, but with development reportedly underway, we could see the tech arrive in the company’s next flagship cycle. It may even arrive in time for the Galaxy Z Fold 7 or Galaxy S26 series.

Until then, Samsung fans may have to keep waiting for that dream combination of big battery, fast charging, and compact size. However, there is at least progress on the horizon, a justification that I don't particularly enjoy having to bring up this late in the game.
