This was reported by Digital Chat Station insider and he added that the Redmi K80 Ultra will support 100W wired charging. Apart from this, it is also reported that the smartphone will feature a yet-to-be-announced Dimensity 9400+ processor from MediaTek as well as a 6.8-inch OLED display with 1.5K resolution and symmetrical thin bezels all around.
