Samsung Galaxy S26 Ultra brings no change in battery compared to the Galaxy S25 Ultra, and newly leaked promo material signals no significant development in the charging aspect, despite the rumored 60W upgrade.
Fresh promo material leaked by @ya_sking12767 gives us an early look at the Galaxy S26 Ultra ahead of its expected February 25 launch. The headline feature everyone wanted to see? Faster charging. Maybe even a bigger battery.
Battery
If you were hoping for a massive upgrade, you might want to lower your expectations. Yes, there is talk of 60W charging. No, the battery is not bigger, and the leaked 30-minute charging figure tells a story that users will recognize.
The Galaxy S25 Ultra launched with a 5,000mAh battery. The Galaxy S26 Ultra, based on leaked materials, keeps the exact same capacity. From a hardware perspective, 5,000mAh is mature and safe, but it’s unexciting.
Charging
Rumors have pointed to a jump from 45W to 60W wired charging on the S26 Ultra. But the leaked promo slide says 75 percent in 30 minutes, which is exactly what Samsung advertised for the S25 Ultra with 45W charging.
If those numbers are accurate, then in real-world use, we are looking at the same charging curve. Peak wattage does not equal sustained wattage, as mobile devices rarely pull max power for the entire session.
Unless the South Korean tech giant has improved efficiency in the final 0 to 100 stretch or optimized thermal management to maintain higher speeds longer, the practical battery charging gain could be negligible.
I think there's a clear jump to 60W charging, which could really cut down charging time way more than the rumors say. Since this is tech field and Samsung's a pioneer in experimenting and optimizing charging speeds, I bet the changes will definitely show results. Let's hope for the best, bro ❤
