Samsung refused to jump onto the silicon-carbon<\/a> (Si\/C) battery bandwagon until the technology was truly ready for mass adoption, taking a morally upright stand that cost it dearly, especially in China, where local players have been happy to run with battery capacities as high as 10,000mAh.<\/p>\n

Now, however, one tipster believes Samsung has cracked the silicon-carbon battery longevity code, and that the Galaxy S27 will “most likely” ship with such a battery, replete with a much higher capacity than the 5,000mAh level that seems to have become a norm for the South Korean tech giant lately.<\/p>\n

Samsung is going all in on silicon-carbon battery tech now that it has almost cracked the underlying longevity code<\/p>\n

For the benefit of those who might not be aware,\u00a0silicon-carbon (Si\/C) batteries\u00a0differ slightly from conventional lithium-ion ones in their choice of the anode, which is made up of a fracture-resistant, nanostructured silicon-carbon composite material\u00a0instead of the typical graphite.<\/p>\n

So, what’s the catch? Well, a silicon-based anode can hold up to 10x as many lithium ions, essentially increasing the battery’s capacity by orders of magnitude, while allowing for a very slim overall form factor for the battery. On the flip side, these batteries do entail a lower lifespan, especially when compared with their lithium-ion counterparts.<\/p>\n

We reported towards the end of 2025 that Samsung SDI was testing a 20,000mAh dual-cell silicon-carbon battery<\/a>, where the primary cell had a 12,000mAh capacity and a thickness of 6.3mm, while the secondary cell retained a capacity of 8,000mAh and a thickness of 4mm. That cell, however, failed at 960 charge cycles<\/a> vs. Samsung’s internal target of 1,500 cycles, prompting the South Korean tech giant to start exploring lower capacity cells.<\/p>\n

Samsung has also been testing an 18,000mAh cell and a 12,000mAh one, which pairs a 6,800mAh cell (thickness of 4.7mm) with a 5,200mAh cell (3.2mm thickness).<\/p>\n

This brings us to the core of today’s topic. The tipster Schr\u00f6dinger has disclosed in a new blog post<\/a> that “Samsung’s engineers are actively reworking the separator layers, stacking architecture, and battery management firmware” to extend the longevity of its silicon-carbon batteries to 1,500 charge cycles. The tipster goes on to note:<\/p>\n

“Reports from multiple sources point to a Silicon-Carbon smartphone being in active preparation, with the Galaxy S27 Ultra as the most likely first deployment.”<\/p>\n

Samsung has largely stayed with 5,000mAh batteries in its smartphones for nearly a decade, with the Galaxy A9 Pro, released all the way back in 2016, constituting one of the first such phones from the South Korean tech behemoth to sport this now-generic capacity. As such, given the amount of time and resources that Samsung has dedicated to its silicon-carbon battery experimentation, one would hope that the consumer-facing debut of this new technology would come with meaningful improvements, and not a repeat of the Galaxy Note 7 saga<\/a>.<\/p>\n
