The Galaxy S26 Ultra is set to be a significant upgrade in Samsung’s flagship lineup, particularly in the area of charging. While the S25 Ultra maintained a 5,000mAh battery, the new S26 Ultra will continue with this capacity. However, the real improvement lies in the charging speed. The S25 Ultra supported 45W charging, but thanks to a recent leaked code, we now know that the Galaxy S26 Ultra will support a faster 60W charging rate, a long-awaited upgrade for Samsung’s top-tier smartphones. 
This move comes after years of Samsung’s reluctance to improve charging speeds on its premium devices, which had left many users frustrated.
Despite rumors suggesting that Samsung might increase the battery size with the adoption of silicon-carbon technology, it seems the company is sticking with a 5,000mAh battery for the time being. This has been the standard for several generations of Samsung devices, and while other manufacturers have made strides in battery size and charging speeds, Samsung is focusing on refining its existing setup.
The 60W charging speed is expected to significantly reduce charging times, giving users faster power-ups when they need it most. This is a welcome change for Galaxy fans, especially since earlier models were limited to 45W charging. There’s no official word yet on the charging capabilities of the other models in the S26 series, but the S26 Ultra’s 60W support is a step in the right direction.
As for the battery life improvements, Samsung is likely to rely on optimized software and AI enhancements. We saw similar efficiency improvements with the Galaxy S25 Edge, and it’s expected that the S26 Ultra will also leverage AI to maximize battery performance. Still, there’s only so much that software can do before hardware limitations become a problem. With Chinese competitors pushing for faster charging and larger batteries, many hope Samsung will soon consider adopting silicon-carbon batteries to stay competitive.
