Vivo came to MWC 2026 in Barcelona with plenty to show off, but one device at its booth drew attention for a different reason. While the company has been openly promoting the camera-focused X300 Ultra, visitors noticed another handset quietly displayed nearby, one that appears to be the long-rumored Vivo X300 Max.
The handset appeared alongside information referencing MediaTek’s upcoming Dimensity 9500 processor, and was described simply as an existing member of the X300 series. Well-known leaker Roland Quandt quickly connected the dots. He pointed to a device labeled V258A, likely related to the previously rumored V2548A model number. That identifier recently surfaced in 3C certification documents, which also revealed support for 90W wired charging.
Images shared by Vivo executive Han Bo Xiao seem to show the same handset, strengthening the case that the device on display is indeed the Vivo X300 Max.
One of the clearest visual differences appears to be the rear camera layout. Unlike the X300 and X300 Pro, the Max features a slightly different arrangement: two lenses sit on either side of the Zeiss T* branding, while a third lens is positioned above them.
Rumors suggest the phone could feature a 6.78-inch LTPO OLED display with a 1440p resolution. Perhaps even more notable is the battery capacity being discussed: a massive 7,000 mAh unit, which could translate into impressive battery life.
Vivo hasn’t formally acknowledged the X300 Max yet, but its quiet appearance at MWC hints that the company may be preparing to expand the X300 lineup sooner rather than later.
If the X300 Ultra is aimed at photography enthusiasts looking for maximum camera capabilities, the X300 Max could end up serving as the more balanced flagship, combining strong performance, long battery life, and versatile cameras.
