vivo is reportedly developing the X300s, a forthcoming addition to its X300 series. Following the October 2025 release of the X300 and X300 Pro, industry speculation suggests the X300s will launch in Q1 2026, spanning the months of January through March.
A key differentiator of the X300s is anticipated to be its substantial battery capacity. Initial reports indicate the device will be equipped with a 7,000 mAh battery. This represents a significant increase compared to the X300’s 6,040 mAh battery. Furthermore, the X300s is projected to integrate the upcoming MediaTek Dimensity 9500+ System-on-Chip (SoC). Based on historical precedent, the “plus” designation typically denotes a minor performance enhancement over the base Dimensity 9500 SoC.

The larger battery capacity is expected to be a prominent selling point for the X300s. While details concerning other specifications remain unavailable, the device is expected to represent a moderate evolution relative to the existing X300 model. Further information will be disseminated as it becomes available.
