Vivo is positioning the X300 Ultra as a high-performance Android flagship designed primarily for multimedia and video production. The device features a dual-camera system capable of 8K recording and 4K video at 120 fps with Dolby Vision support. It introduces a new Pro-Videomode offering cinematic looks and image stabilization comparable to the Samsung Galaxy S25 Ultra; however, tests have revealed noticeable autofocus issues during rapid movements, indicating that while impressive, the system is not yet flawless. Furthermore, Vivo plans to leverage the X300 Ultra’s camera hardware for a new gimbal mini-camera equipped with a 200-megapixel sensor, expected to launch in China by year-end as a direct competitor to devices like the DJI Osmo Pocket 4.

When benchmarked against the Samsung Galaxy S26 Ultra, the Vivo X300 Ultra shows distinct trade-offs in performance and thermals. While it suffers from inferior audio quality and higher operating temperatures that can peak at 55°C under load, it maintains superior sustained performance due to less aggressive thermal throttling compared to its rival. This makes the Vivo device particularly attractive for users engaged in long-duration intensive tasks or heavy gaming, where consistent frame rates are prioritized over peak silence or cooler surface temperatures. Critics note, however, that the high heat output remains a significant concern for comfort and battery longevity during prolonged use.

For consumers, purchasing options vary significantly between regions. The European version of the X300 Ultra includes a 100W charger in the box along with a protective case, addressing recent industry norms but at a premium price point. In contrast, the Chinese version is available for import starting at approximately €930, offering substantial savings despite minor software limitations such as restricted Google services and a lack of native eSIM support. While the hardware performance and warranty conditions are largely comparable to the official EU model, European buyers must decide whether to prioritize cost efficiency with imported units or opt for the official version, which promises longer confirmed software support.
