For the past few years, we’ve been seeing Chinese brands launching smartphones with bigger and bigger battery capacities. To now, we’re seeing phones with 10,000mAh capacity batteries, and they aren’t that much thicker than the Galaxy S26 Ultra. So why hasn’t Samsung adopted Silicon-Carbon?
Well, the most obvious answer is the Galaxy Note 7. But this week, here in San Francisco, we had the chance to pick the brains of a few Samsung execs during the Galaxy S26 series announcement and asked about Silicon-Carbon batteries. Essentially, it boils down to the fact that they need to meet their internal requirements. Which are likely more stringent than what other OEMs have, seeing as Samsung did have to recall the Galaxy Note 7 twice.
But the good news is, Samsung is already evaluating silicon-carbon batteries. Some other executives have told us that this is “an unproven technology” which is kind of not true. Since we’ve had them in smartphones for over 5 years now. So it’s nice to see Samsung kind of confirm that they are at least testing out the tech.
For a premium phone not using a silicon-carbon cell, Samsung did a good job with the Galaxy S26 Ultra. The company even made it thinner than last year’s model. This translates to an excellent in-hand feel when using it without a case, and a not-bulky result when using a case (even rugged ones, like ROKFORM’s latest models). So, it’s interesting to think about what the brand can achieve using this technology.
The supply chain could be a concern for future phones with silicon-carbon
Something to keep in mind here is that Samsung is a fairly large smartphone maker, usually in the top two globally. Which means that they would need a ton of these silicon-carbon batteries for the Galaxy S lineup. Way more than OPPO, HONOR, OnePlus or any of these other Chinese brands would need.
So, it’s not quite as simple as testing out silicon-carbon, it meeting requirements and popping it into the Galaxy S27 Ultra next year. The Galaxy S25 Ultra sold about 11 million units in the first year that it was available. Which is no small number and that’s a huge number of batteries it would need to secure.
But, Samsung might be putting silicon-carbon batteries in its smartphones sooner than you think.
