Vivo upcoming flagship, the X300 Ultra, has surfaced again—this time with new details pointing to a larger battery and upgraded charging capabilities. The information first appeared on reliable tech publication. The leak arrives just weeks before the phone’s expected debut, adding to the steady stream of information surrounding Vivo’s next premium device.
According to early reports, the X300 Ultra is set to feature a 5,500mAh battery, marking a noticeable step up from the X200 Ultra’s 5,000mAh unit. The upgrade suggests Vivo is aiming for longer endurance, especially with the flagship expected to run a brighter display and more power-hungry imaging hardware. The device is also rumored to support 100W wired charging and 50W wireless charging, aligning it with the fastest standards currently offered in the Android flagship segment.
Design details point to a familiar silhouette, with a curved display, metal frame, and a large camera housing that continues Vivo’s focus on high-end mobile photography. While full camera specifications have yet to leak, the X300 Ultra is expected to build on the company’s custom optics partnership and the variable-aperture system introduced in the previous generation.

The leaked figures have already drawn attention from early enthusiasts. Users on tech forums welcomed the battery jump, noting that the X200 Ultra delivered strong endurance and that additional capacity could help offset the demands of next-generation chipsets. Industry watchers say the charging upgrade is expected, as several competitors are moving toward 100W-class fast charging as a flagship baseline.
If accurate, the enhancements position the X300 Ultra to compete more directly with the next wave of premium Android devices launching in early 2026. The improved battery and charging performance could give Vivo an edge in markets where power efficiency and quick top-ups heavily influence purchasing decisions.
Vivo is expected to announce launch timelines soon, with pre-orders likely to follow shortly after the official reveal. Software details, camera breakdowns, and regional availability are still under wraps and should become clearer as the company moves closer to the event.
The X300 Ultra remains unconfirmed by Vivo, but the growing number of credible leaks suggests the flagship is nearing its debut—setting up what could be one of the first major smartphone announcements of the coming cycle.
