Samsung has been quite conservative when it comes to implementing fast charging speeds on its devices. The charging speed was raised to 45W with the Galaxy S20 Ultra but was reduced to 25W with the Galaxy S21 Ultra. However, the company resumed offering 45W fast charging with later Ultra models.
Compared to rival Android brands, Samsung still lags behind. While other brands are offering fast charging speeds of up to 240W (Realme GT 5), the Korean brand remains stuck at 45W fast charging with its latest Galaxy S25 Ultra. That might change with next year"s Galaxy S26 Ultra.
According to prominent leaker IceUniverse of X (formerly Twitter) says that the Galaxy S26 Ultra will feature the fastest charging speeds in the company"s history. While the leaker didn"t specifically mentioned an exact number, it is expected to exceed the current 45W limit, if this leak turns out to be true.
It is 100% confirmed that Samsung S26 Ultra will exceed the charging power of 45w！

Achieve the fastest charging speed in Samsung"s history.
Samsung has been cautious, particularly following the Galaxy Note7 fiasco. The company has been delaying any upgrades to fast charging speeds ever since. However, it appears that Samsung is now ready to step things up, though it still won"t be including a charging brick inside the box, citing environmental concerns.
It is not certain if Samsung is also considering debuting a high-capacity battery with the Galaxy S26 Ultra or not. The current flagship, the Galaxy S25 Ultra, comes with a 5,000 mAh battery. The leaker, who has a solid track record claims the information is "100% confirmed."
Still, this should be taken with a huge grain of salt, as we are months away from launch.
Let us know in the comments below if you are excited about this development, and whether you would prefer Samsung to include a charging brick inside the box instead of just increasing the charging speed.
