Vivo is expected to unveil the Vivo X300 Ultra later this month, and speculation suggests the brand may also introduce the Vivo X300 Max alongside it. The X300 Max was reportedly displayed in a confidential case at MWC 2026 recently. Today, Vivo Product Manager Han Boxiao confirmed that there is no Vivo X300 Max. Instead, this device will debut with the Vivo X300s branding. He also confirmed several details about the device.
Vivo X300s moniker confirmed
According to Boxiao, the company had internally discussed naming the device the Vivo X300 Max due to the scale of its upgrades. However, Vivo eventually chose to keep the “s” naming convention, similar to the previous X-series refresh.
The Vivo X300s is aimed at users who want a large-screen flagship without compromising on imaging. While many recent imaging-focused models have shifted to compact displays, this device combines a bigger screen with strong camera capabilities.
The “s” reportedly stands for “SuperMax,” highlighting improvements across multiple areas, particularly performance. Vivo also suggests that the X300s will sit alongside the X300 Ultra, offering a balance between powerful photography and flagship hardware.
Boxiao revealed that the Vivo X300s will have a 6.78-inch BOE Q10 Plus panel with a 144Hz refresh rate. This would make it the first device in the X series to support such a high refresh rate, and it is also said to support native 144FPS gameplay in certain MOBA titles. The display will support Zeiss color tuning and circular polarization technology designed to improve eye comfort.
Audio performance is also set to improve with the inclusion of symmetric 1115 dual speakers similar to those found on the iQOO 15. The system includes upgraded amplifiers and algorithms to deliver a wider sound field. Vivo claims that gaming audio cues such as footsteps and gunfire can become significantly clearer, helping players identify positions more easily.
The phone will also include a large customized 4D vibration motor designed to deliver stronger and more detailed haptic feedback. The motor is said to support enhanced vibration effects in more than ten popular mobile games, allowing users to experience stronger tactile responses during gameplay. He added that this will be the largest and most powerful vibration motor ever included in an X-series device.
Boxiao has also confirmed that the device will be equipped with a Zeiss 200-megapixel image sensor. However, he did not reveal any other camera-related information.
Previous reports have revealed that the X300s will feature a 50-megapixel periscope telephoto camera in its triple camera setup. It will have a Dimensity 9500 chip and a battery of around 7,000mAh capacity. It may offer 90W wired and 40W wireless charging and run on OriginOS 6-based Android 16. It is also said to have an IP68/69-rated dust- and water-resistant chassis.
