The latest news from the industry shows that Samsung is still very cautious about abandoning traditional lithium batteries and fully switching to new silicon carbon (Si-C) anode battery technology on its next-generation top flagship smartphone Galaxy S27 Ultra. Surprisingly, the root cause of Samsung's hesitation is not the uncertainty of the battery technology itself, but the extremely high manufacturing costs behind it.
According to details disclosed by overseas whistleblowers on encrypted social platforms, the reason why Samsung has stayed away from silicon-carbon batteries, at least for now, is mainly because of the huge disparity in procurement costs. Data shows that for every 10 million traditional lithium-ion batteries purchased, Samsung only pays US$12 million to US$15 million; however, if the Galaxy S27 Ultra switches to high-density silicon carbon batteries for the same shipment volume, its procurement cost will soar to US$22 million to US$28 million. Considering that the global PC and smartphone industries are currently in the midst of a DRAM memory shortage crisis, the rise in memory purchase costs has greatly squeezed the profit margins of hardware manufacturers. Therefore, in order to avoid any unnecessary supply chain cost stacking, Samsung is doing everything possible to avoid additional financial risks.
Although manufacturing costs hinder the implementation of new material batteries, this does not mean that Samsung has chosen to stop making progress in battery life. On the contrary, the latest test information shows that Samsung is currently re-evaluating the new battery technology roadmap provided by Samsung SDI and actively testing new battery units with capacities between 5600mAh and 5800mAh to replace the 5200mAh traditional lithium battery solution that has been basically finalized.
If this round of intensive testing can be successfully passed, the Galaxy S27 Ultra is expected to eventually be equipped with a large-capacity battery with a rated capacity of more than 5500mAh. This will also be the first substantial breakthrough in battery capacity for Samsung’s previous Ultra flagship models since the Galaxy S20 Ultra first touched the 5000mAh ceiling.
Although compared to the aggressive adoption of silicon-carbon batteries and even large-capacity solutions of more than 6,000 mAh by Chinese smartphone manufacturers in their flagship phones, Samsung’s final specifications may still be conservative in terms of parameters, but the industry generally expects Samsung to make up for the generation gap in hardware through in-depth optimization of the system. For example, if Apple also improves battery capacity in future iPhones, Samsung can rely on refined underlying adjustments for the new generation OneUI system to significantly reduce power consumption in specific daily use scenarios, thereby extending battery life.
In addition, due to previous rumors in the market that the Galaxy S27 Pro with slightly lower specifications will also be equipped with a 5000mAh battery, Samsung executives obviously do not want consumers to find any reason to "skip the Ultra version". In the context of the current memory crisis that threatens and may suppress the overall demand for global smartphones, packing more power into top-end models through structural optimization is undoubtedly the most pragmatic strategy for Samsung to consolidate its flagship market share in the short to medium term and fight against competitors such as Apple.
