Earlier this month, a leak from @chunvn8888 suggested Samsung was finally ready to push past the 45W charging speed that’s defined its Ultra models for years. According to that rumor, the upcoming Galaxy S26 Ultra would support 65W wired charging—finally catching up, at least partially, to the competition. However, a new report casts doubt on that claim.
60W not 65W
Recent information from @erenylmaz075 confirmed that Samsung will use 60W, not 65W. The information comes from digging into the code of Samsung’s One UI 8 software. Inside, references were found pointing to a maximum charging capacity of 60W.
While the difference between 60W and 65W may seem minor, it still means Samsung won’t be matching some rivals in peak speeds. It also raises questions about whether the earlier leak was simply wrong or based on early hardware testing that didn’t make it to production.
That said, 60W would still be a step up from the 45W limit that has defined Samsung’s flagships since the Galaxy S20 Ultra. If it ends up being true, users can expect slightly faster charging times, though nowhere near what brands like Xiaomi, Realme, or OnePlus currently offer. Some of those already support charging speeds well over 100W—even 150W in some cases.
Battery size still unclear
The confusion doesn’t end with charging speed. The battery size of the S26 Ultra is also under debate. The same rumor that claimed 65W charging also said the device would feature a 5,500 mAh battery—an increase of 10% over the 5,000 mAh battery in the Galaxy S25 Ultra. But newer reports from @iceuniverse dispute this. The latter claims that the S26 Ultra will stick with the same 5,000 mAh capacity as its predecessor. If that’s true, the slightly faster charging might be Samsung’s way of compensating for the unchanged battery size.
Taken together, it’s becoming increasingly clear that while the Galaxy S26 Ultra will offer modest upgrades in power management, it won’t lead the pack in either charging speed or battery life. Samsung appears to be continuing its cautious, incremental approach rather than going all-in like some of its Chinese competitors.
So far, Samsung hasn’t confirmed any of these specs. But with leaks stacking up, expectations are forming around a phone that slightly improves on its predecessor without making big leaps. And for power users hoping for dramatic gains in battery or charging tech, that may end up being a disappointment.
