While the highly anticipated Samsung Galaxy S26 Ultra is still in the works, recent reports indicate that the phone may not deliver on battery improvements. Following Samsung's trend of cautious battery innovations, it is expected that the Galaxy S26 Ultra will feature a similar battery size to its predecessor, the Galaxy S25 Edge. With a rumored 5,000 mAh battery capacity, any potential increase is likely to stay below 5,400 mAh. This news comes as other phone manufacturers, such as Xiaomi and Oppo, are utilizing better batteries in their devices, highlighting a slower progress among major players like Samsung, Apple, and Google. Despite the competition's advancements, it appears that Samsung is prioritizing slim designs over larger battery capacities. Stay tuned for more updates on the Galaxy S26 Ultra's battery specifications.
