The Galaxy S26 Ultra Could Finally Come With Battery Tech
A new rumor suggests Samsung is designing batteries with stack technology which could help them with their future Galaxy flagship in increasing the size of their battery.
Unfortunately, this isn’t coming in the upcoming S25 series as the S25 Ultra is supposed to stay at 5000mAh which have been the same for some years now. Meanwhile, we have smartphone brands from China surprising us with huge battery capacities on their flagship smartphones for at least a year thanks to silicon carbide (SiC) batteries. Examples include the Honor magic 7 pro, Oppo Find X8 Pro, OnePlus 13 and others, all sporting batteries above the 5,500mAh mark.
However, Samsung is reportedly taking a different approach to ensure you won’t toss a Galaxy S26 Ultra in the trash for a lack of battery upgrades. Samsung SDI is said to be working on batteries with stacked technology. The tech would ensure around 10% higher energy density compared to the traditional method, so we might have to wait to Galaxy S26 Ultra to see some changes in the battery aspect like a 5,500mAh.
Samsung seems to be sticking with Li-ion and thus the Galaxy S24 Ultra and likely the upcoming S25 Ultra are stuck with 5,000mAh battery cells. The stacking method, just like using a SiC battery, would allow a 10% higher energy density. Likely Samsung will reserve this method only for flagships though (as its manufacturing is expensive) so don’t expect to see a huge battery on a Galaxy A phone anytime soon.
