Vivo X300 Leaks: Battery Size, Certification, and Possible September Launch
The much-anticipated Vivo X300 leaks are gaining traction as the upcoming smartphone series continues to appear on official Chinese certification platforms. Recently, the alleged Vivo X300 and X300 Pro were spotted with CMIIT certification, revealing a massive 6,375mAh battery and satellite connectivity support on one variant.
With radio and CMIIT certifications already cleared, the series is now only a 3C approval away from launch. Industry insiders believe Vivo may announce the X300 lineup in September in China.
CMIIT Certification Confirms Battery and Satellite Features
The device carrying model numbers V2502A and V2502DA has surfaced in China’s CMIIT database. Key takeaways include:
- Battery Size: 6,375mAh (rated value)
- Operating System: Android 16
- Satellite Support: The “DA” variant supports short messaging via Beidou-3 satellite
This certification strengthens rumors that the DA model could be marketed as the Vivo X300 Pro, offering satellite messaging as an exclusive feature.
Dimensity 9500 to Power the Vivo X300 Series
Reports suggest that the Vivo X300 series launch will mark the debut of MediaTek’s latest flagship processor, the Dimensity 9500. A Vivo phone with the model number V2509 recently appeared on Geekbench running the D9500 chipset, likely making it part of the lineup.
- V2509A: Expected to be the standard Vivo X300
- V2502A/DA: Likely the Vivo X300 Pro with optional satellite messaging
If true, Vivo will be the first brand to introduce Dimensity 9500 smartphones globally, giving it an edge in performance and efficiency.
What to Expect Next
The Vivo X300 and X300 Pro are shaping up to be powerful contenders in the premium smartphone market. Based on current leaks:
- A September 2025 launch in China seems likely
- The series could debut globally later in the year
- More certifications (TENAA, 3C) are expected in the coming weeks
As more details emerge, expectations are high that the Vivo X300 Pro battery size and cutting-edge chipset will position the device as a strong rival to upcoming flagships from Samsung, Xiaomi, and Oppo.
Final Thoughts
The Vivo X300 leaks provide a solid picture of what’s coming: huge battery life, next-gen performance, and satellite messaging support. With launch timelines aligning for September, Vivo fans won’t have to wait long to see if the X300 series lives up to the hype.
