Even though the Galaxy S25 Edge was released just a few months ago, the Galaxy S26 Edge rumor mill started spinning as the latest evidence suggests the successor will launch alongside the rest of the S26 phones, possibly replacing the Plus model.
The latest Chinese 3C regulatory body listed the Galaxy S26 Edge’s battery details, refuting the previous rumors about a potential battery upgrade. According to the 3C listing, Samsung will stick to the lithium-ion battery tech and won’t make the transition to the silicon-carbon batteries for yet another year.
Most competitors are already making the shift to silicon-carbon batteries as they provide higher energy density, allowing for either bigger batteries in the same form factor or reducing the phone’s size altogether.
Still, Samsung will offer a modest capacity bump, from 3,900 mAh this year to 4,200 mAh. This will surely boost battery endurance, but we are still somewhat disappointed because if Samsung had made the shift to silicon-carbon, we would have probably seen a battery that’s around 5,000 mAh.
