Samsung may finally be ready to step up its charging game with the upcoming Galaxy S26 Ultra. According to a new leak, the flagship is “100% confirmed” to ditch the long-standing 45W limit and support true fast charging.
On July 23, reliable tipster @UniverseIce posted on X: “It is 100% confirmed that Samsung S26 Ultra will exceed the charging power of 45!” If true, this would mark the first upgrade in charging speed since the Galaxy S22 Ultra, which stuck with 45W despite growing demand for quicker top-ups. For reference, the Galaxy S25 Ultra’s 5,000mAh battery takes about an hour to fully charge at 45W; a previously speculated 65W bump could shave off 15 minutes or more.
Samsung has long been conservative with battery and charging tech—especially after the Galaxy Note 7 debacle—so this shift is drawing attention. Unlike most rivals from China that rely on proprietary tech, Samsung is expected to stick with the USB PD PPS standard. However, that doesn’t ensure compatibility with third-party PD PPS power bricks. Users with such power bricks may still need to buy an official (and possibly expensive) Samsung charger to take full advantage of the faster speeds.
As for the rest of the phone, the S26 Ultra is rumored to keep its 5,000mAh battery, but Samsung may have improved the energy density to make room for a slimmer profile. Sources suggest Samsung will stick with traditional lithium-ion cells, keeping capacity under 5,400mAh.
Beyond battery, charging, a chipset upgrade, and some added AI, the S26 Ultra is rumored to offer few major changes compared to its predecessor. The S26 Edge is expected to replace the current Plus model, while the Ultra could feature a new 200MP telephoto lens and run One UI 8.5, with refined and new AI features positioned as key highlights.
With a Q1 2026 launch window, the Galaxy S26 Ultra’s jump to slightly faster charging could be a welcome change for Galaxy fans frustrated by Samsung’s slow pace in this area. But will it be enough to keep up with competitors like the OnePlus 15 or the vivo X300 Ultra? Time will tell, as more leaks and details continue to emerge.
