We are getting it ready for future phones
In the long arc of technological adoption, speed and caution have always competed for the soul of innovation. Samsung's decision to ship the Galaxy S26 without silicon carbon batteries is not a failure of imagination but a deliberate act of restraint — the company acknowledging its own conservatism while insisting that a technology must prove itself worthy of the hundreds of millions of people who will depend on it. Where rivals like OnePlus and Xiaomi have moved first, Samsung is choosing to move carefully, shaped in no small part by the memory of what happens when that calculus goes wrong.
- Samsung launched its 2026 flagship phones without the battery upgrade the industry had anticipated, leaving the Galaxy S26 reliant on conventional lithium-ion cells while competitors have already moved on.
- The company's own executive admitted Samsung has been 'un-innovative' on batteries, a rare moment of corporate candor that underscores the tension between market pressure and internal caution.
- Silicon carbon batteries expand during charging, degrade faster over time, and carry safety risks that Samsung — still haunted by the Galaxy Note 7 recall — is unwilling to accept without long-term data at scale.
- OnePlus and Xiaomi have shipped the technology without reported incidents, narrowing Samsung's window to claim the upgrade as a meaningful differentiator before it becomes table stakes.
- Samsung's R&D head confirmed the company is actively preparing silicon carbon batteries for future flagships, framing the S26 as a deliberate pause rather than a dead end.
Samsung's Galaxy S26 has arrived without the battery technology many expected. While competitors OnePlus and Xiaomi have already shipped silicon carbon cells in their latest flagships, Samsung chose to stay with traditional lithium-ion — a decision the company's own executive described as being 'a bit un-innovative,' even as he defended it as intentional.
Sung-Hoon Moon, Samsung's Head of Smartphone R&D, explained the reasoning ahead of the Galaxy Unpacked event. Silicon carbon batteries offer higher energy density in theory, but Samsung is not satisfied that the real-world gains justify the risks. The cells degrade faster than lithium-ion alternatives and expand more during charge cycles — a property that raises safety concerns in tightly engineered devices. For Samsung, that concern is not abstract. The Galaxy Note 7 battery crisis of 2016 left a lasting imprint on how the company approaches anything that could fail at scale.
The technology is not unproven elsewhere. OnePlus reports its silicon carbon implementation retains 80 percent capacity after four years, and neither it nor Xiaomi has faced widespread safety issues. Apple and Google have also held back, suggesting the caution among the largest manufacturers reflects the asymmetric stakes of deploying any battery technology to hundreds of millions of users.
Samsung is not walking away from silicon carbon. Moon confirmed the company is actively preparing it for future phones, positioning the S26 as a pause in a longer journey. The question the industry is now watching is not whether Samsung will adopt the technology, but whether it can do so before the upgrade stops feeling like a leap forward.
Samsung's new flagship phones are arriving without the battery upgrade many expected. The Galaxy S26 series, unveiled at the company's 2026 event, continues to rely on traditional lithium-ion cells rather than adopting silicon carbon technology, which competitors like OnePlus and Xiaomi have already begun deploying in their latest models. The decision marks another year of incremental battery progress from a company that, by its own admission, has grown cautious on this particular front.
Sung-Hoon Moon, Samsung's Executive Vice President and Head of Smartphone R&D, addressed the gap directly during a roundtable discussion ahead of the Galaxy Unpacked event. When asked about the company's battery strategy, he acknowledged that Samsung had been "a bit un-innovative" in this area. But the explanation that followed revealed something more deliberate than mere neglect: silicon carbon batteries, despite their theoretical advantages, have not yet cleared the hurdles Samsung has set for them.
The company's validation standards are stringent. Silicon carbon cells promise higher energy density than lithium-ion alternatives, which in theory means longer battery life or smaller, lighter phones. But Samsung is not convinced the real-world gains justify the risks. Moon emphasized that customer experience remains the ultimate measure—and that Samsung will only adopt the technology once it's confident the switch will actually improve how people use their phones, not just add a specification to a marketing sheet.
There are legitimate technical concerns underpinning this caution. Silicon carbon batteries degrade faster than their lithium-ion counterparts, which means they might start with more capacity but lose it more quickly over time. They also expand more during charging and discharging cycles, a property that could pose safety risks in a device as tightly engineered as a smartphone. For Samsung in particular, this concern carries historical weight. The Galaxy Note 7 debacle of 2016—when batteries caught fire and the company issued a global recall—left a mark on the organization's approach to battery safety.
Yet the technology is not unproven in the market. OnePlus has shipped silicon carbon batteries in the OnePlus 15, and Xiaomi has done the same with the Xiaomi 17 Ultra. OnePlus claims its implementation maintains 80 percent of original capacity after four years of use, and neither company has reported widespread safety incidents. This suggests the risks, while real, may be manageable with proper engineering.
Samsung's hesitation appears to stem less from technical impossibility than from the absence of long-term safety data at scale. Apple and Google have similarly held back from adopting the technology in their flagship devices, suggesting the caution is industry-wide among the largest manufacturers. The stakes of a battery failure in a phone sold to hundreds of millions of people are simply too high to move quickly.
But Samsung is not ignoring silicon carbon altogether. Moon made clear that the company is actively preparing the technology for future phones. "We are getting it ready," he said, signaling that the S26 represents a pause, not a permanent decision. The implication is that once Samsung's validation process is satisfied—once the company believes the technology is safe at scale and delivers meaningful improvements to how customers experience their phones—silicon carbon batteries will arrive in Samsung flagships. The question is not whether, but when.

La Conversación del Hearth Otra perspectiva de la historia
Why did Samsung decide to skip silicon carbon batteries for the S26 when competitors are already using them?
Samsung's leadership made a deliberate choice based on their own validation standards. They're not saying the technology doesn't work—they're saying it hasn't proven itself safe and beneficial enough at their scale yet.
But OnePlus and Xiaomi are shipping these batteries now without major problems. Doesn't that suggest Samsung is being overly cautious?
Possibly. But Samsung is also the company that had to recall millions of Note 7 phones because of battery fires. That kind of incident shapes how a company thinks about risk. The scale matters too—Samsung sells far more phones than OnePlus does.
What exactly are they worried about with silicon carbon batteries?
Two main things. First, they degrade faster than lithium-ion, so you might start with a bigger battery but lose capacity more quickly over time. Second, they expand more during use, which could be a safety hazard if not managed perfectly.
And Samsung thinks they can solve these problems eventually?
Yes. They said explicitly they're "getting it ready" for future phones. They're not rejecting the technology—they're just not confident enough yet that it will actually improve the customer experience enough to justify the risks.
So what has to happen before Samsung adopts it?
The technology has to pass their rigorous validation standards and demonstrate real-world benefits. It's not just about specs on paper. Samsung wants to know that customers will actually feel a meaningful difference in how their phones work.
How long do you think that takes?
That's the open question. Samsung didn't give a timeline, but the fact that they're actively working on it suggests it could arrive in the next generation or two of flagships, not years away.
