We already know that Vivo is preparing to unveil its next-generation Vivo X300 series. Just days before the official launch, new details about the battery capacities and charging features of the Vivo X300 and Vivo X300 Pro have surfaced online. Here’s what we know.
According to a leak from tipster Anvin @ZionsAnvin on X (formerly Twitter), the Vivo X300 will be equipped with a 6,040mAh battery, while the X300 Pro will house an even larger 6,510mAh unit. Both models will reportedly support 90W wired fast charging and wireless charging capabilities, as previously hinted through 3C certification.
The images in the post also highlight other key specifications including the 4.21GHz MediaTek Dimensity 9500 chipset, 16GB of physical RAM, 16GB of virtual RAM expansion, and up to 1TB of internal storage, confirming these as top-tier flagship offerings.
Meanwhile, Vivo Product Manager Han Boxiao has officially confirmed that both the Vivo X300 and X300 Pro will feature a USB-C 3.2 port. This is a step up from last year’s Vivo X200, which was limited to USB 2.0 support.

Similarly, iQOO Product Director Galant V confirmed that the upcoming iQOO 15 will also include a USB-C 3.2 port.
Vivo has already teased several premium features for the X300 lineup. Both smartphones will sport BOE Q10 Plus Eye-Protection Displays, a Zeiss 200MP camera system, and a Zeiss 2.35x teleconverter for enhanced photography.
