As Chinese smartphone makers embrace silicon-carbon batteries with open arms to obtain an edge against their competitors, Samsung and Apple appear to be falling behind in this race, instead resorting to mass producing other energy-efficient components in the hopes of offsetting increased battery drain. The Korean giant was earlier reported to be reviewing a plan to bring this technology to the Galaxy S26 family, with the company possibly adding a generously large 7,000mAh cell to one of its models. Unfortunately, a tipster believes otherwise, stating that based on the firm’s internal testing, the battery’s capacity for the next smartphone family has not even crossed 5,500mAh.
Tipster appears overconfident in his claims, says he will delete his X account if Samsung adds even a 6,000mAh battery to the Galaxy S26 Ultra
The maximum capacity that Samsung has ever added to its Galaxy S series is 5,000mAh, with the figure remaining unchanged from the Galaxy S25 Ultra and past releases. According to @PandaFlashPro, future flagship launches, including the Galaxy S26 Ultra, may not feature a monumental change in this regard, as five of his ‘sources’ have informed him of Samsung’s plans. He mentions that the battery capacity has not exceeded 5,500mAh battery but does not state if it is based on silicon-carbon or lithium-polymer technology.
What he does mention is that the 5,500mAh capacity is not the actual value but is lower at 5,396mAh. The tipster appears steadfast in his claims, to the point that he will delete his X account if the Galaxy S26 Ultra ships with a 6,000mAh battery, let alone a 7,000mAh one. Assuming this post is true when we revisit it next year, Samsung is certainly not doing itself any favors in this regard. Then again, a more reliable source mentions that the Korean behemoth is directly involved in the development of silicon-carbon battery materials, so perhaps there is some truth to this.
I’ll delete my Twitter account if Samsung gives the Galaxy S26 Ultra a 7000mAh or even a 6000mAh battery I bet. 🙂
"Based on my Five Sources, the internal Samsung Test Lab only seem to have a Capacity of Max 5500mAh not more".

Switching to silicon-carbon batteries will not only increase the cell’s capacity but also allow Samsung to boost the runtime of its devices without compromising the thickness. This technology can also give the company the much-needed motivation to pursue the releases of Galaxy S25 Edge successors, as their sleek frame coupled with an impressive screen on time will be a preferred combination amongst buyers. The only question is when Samsung will debut this technology. If we were to ask @PandaFlashPro, our disappointment would be through the roof, but we will provide updates to readers in the future.
