Samsung launched the super-slim Galaxy S25 Edge with a 3,900mAh battery this year. Rumors have since emerged that the company may not just increase the capacity on its successor but also go with a silicon-carbon battery. New information has surfaced that reveals this highly anticipated upgrade isn't happening, and that Samsung will stick with a lithium-ion battery for the Galaxy S26 Edge. The Galaxy S26 Edge sticks with a lithium-ion batterySamsung's battery for the Galaxy S26 Edge, bearing part number EB-BS947ABY, has been certified by China's 3C body. The certification listing reveals some key details about this component.It has a rated capacity of 4,078mAh which will be marketed as 4,200mAh. The 4,200mAh figure has been rumored several times already, so it's nicely to see that customers who were waiting for a larger battery on the device before they decided to pick one up will finally have one more reason to drop cash on Samsung's slim flagship. The listing also reveals that this is a lithium-ion battery, not silicon-carbon. Samsung is yet to make a transition to this technology for its smartphones, which would allow for higher capacities without requiring more space inside the shell. The Edge series would be the perfect starting point as Samsung's aim is to make this lineup as slim as possible. Perhaps the company wishes to play it safe and if it can deliver a respectable increase in capacity while sticking with the tried and tested lithium-ion technology, it may be enough to push the transition to silicon-carbon down the road for a little while longer.The post The most anticipated Galaxy S26 Edge battery upgrade isn’t happening appeared first on SamMobile.
