Samsung Galaxy S26 Ultra is expected to come with a powerful fast charging brick, and new information shows that the phone will also come with the fastest ever wire charger.

Last week, Ice Universe said that the Samsung Galaxy S26 Ultra will break the long-standing fast charging limit this time around. Ironically, the most delinquent Galaxy flagship only supports 45W charging.

According to the information coming from X, the upcoming Galaxy S26 Ultra flagship will feature 60W wire fast charging, and it’ll count as a big upgrade from last year’s 45W wired charger.

This new report shows that Samsung is focusing on another important segment – fast charging technology for the Galaxy S26 Ultra, followed by a slim structure.

According to the previous information, Samsung Galaxy S26 Ultra will feature Qualcomm’s upcoming flagship chipset which may be called the Snapdragon 8 Elite 2, new dual 200MP camera of different sizes, a bigger and better display, One UI 85, bigger battery life, and more. As this flagship series is expected to make its debut by next year.

Samsung Galaxy users won’t have to wait long for the One UI 8 update. The company has just started testing Android 16-based One UI 8 on some of its budget models, which is the first step towards rolling out the software update. Now, Samsung has also begun internal testing of One UI 8 on two of its mid-range Galaxy smartphones, the Galaxy F34 and Galaxy M36.

X user Mohammad Khatri spotted internal One UI 8 builds for the Galaxy F34 and Galaxy M36. This development brings these two mid-range phones on par with newer models like the Galaxy A56, Galaxy A36, Galaxy A55, Galaxy A35, Galaxy A54, and Galaxy A34.

For the Samsung Galaxy F34 and Galaxy M36, the One UI 8 builds carry version numbers E346BXXU7EYG7 and M366BXXU1BYG2, respectively. Note that it isn’t the latest build that the Korean tech giant will deliver as part of its official update rollout.

The One UI 8 beta program that started in May this year is still exclusive to the Galaxy S25 series. Don’t expect this beta program to reach non-flagship devices, as the firm has no plans for recent flagship phones either.

The firmware listing does not guarantee an early rollout of the update. It is the first step towards an OTA release on suitable models. You can expect a rollout roadmap from the company, which will be available in the Members app.
