As Samsung’s new flagship smartphone, the Galaxy S25 Ultra is expected to launch early next year. Samsung’s Galaxy S25 Ultra battery and charging details were leaked recently, and now the phone has been spotted on China’s 3C certification website. In addition, Samsung is rumoured to change the Galaxy S25 lineup’s naming scheme from ‘Ultra’ to ‘Note’.

According to 91mobiles, the Galaxy S25 Ultra has been spotted on China’s 3C certification website. The phone is listed with a 4,885mAh battery, which will be marketed as 5,000mAh when it is released. As the battery capacity is the same as the Galaxy S24 Ultra, there’s no upgrade here.

The Galaxy S25 Ultra is also expected to support 45W fast charging. Samsung probably won’t upgrade if these details are true.

The Galaxy S25 Ultra might also change its design. Rumours and renders have suggested that the Galaxy S25 Ultra will have rounded corners to avoid looking boxy. There is a possibility that it will look like the Galaxy S21 Ultra. According to reports, the Galaxy S25 Ultra will have a body thickness of 8.4mm, making it the thinnest Ultra model yet.
