Samsung and Apple appear to be turning to silicon-carbon batteries to break the 5,000mAh capacity limit in their flagship models.
According to new information posted on yeux1122’s blog, Samsung and Apple have begun developing silicon-carbon batteries as they appear to have reached the limit of current battery technology in their flagship models. The Chinese smartphone market has already widely adopted silicon-carbon battery technology, with many devices boasting capacities in excess of 6,000mAh.
Case in point is Xiaomi’s recently announced Redmi Turbo 4, which packs an impressive 6,550mAh battery, while Oppo’s Find X8 Pro has a 5,910mAh battery. In contrast, top models from Samsung and Apple are limited to 5,000mAh, such as the Galaxy S24 Ultra, while the same capacity will reportedly be retained in the upcoming Galaxy S25 Ultra.
According to the same sources, Samsung appears to be actively involved in the development of the materials for the new batteries, although there is no specific timetable for their commercial availability. As for Apple, there are no details on the company’s progress in this area. The biggest challenge for the two companies lies in the space limitations of their premium devices, as they have to keep all their advanced features while also trying to fit larger batteries.
In any case, software optimization and the use of energy-efficient components have reached their limits, making the adoption of new battery technologies essential for future improvements in device autonomy.
