As the year draws to a close, the rumor mill for next-generation flagship smartphones is already spinning at full speed. The latest device to generate significant buzz is the Vivo X300 Ultra, the anticipated top-tier model of the upcoming X300 series. While its official launch is not expected until next year, a recent certification in China has provided the first concrete hardware detail, fueling speculation about the phone's other potential high-end features.
Certification Reveals 100W Fast Charging Capability
A Vivo smartphone with the model number V2536A has received certification from the China Quality Certification Centre, a key regulatory body. The listing confirms the device supports 100W wired fast charging, specifically using the 20V at 5A USB Power Delivery (PPS) standard. This specification is widely believed to belong to the yet-to-be-announced Vivo X300 Ultra. The 100W rating represents a notable upgrade from the 90W charging found on the current Vivo X200 Ultra, promising significantly reduced charging times for what is rumored to be an even larger battery.
Charging Comparison with Predecessor:
| Feature | Vivo X200 Ultra (Released 2025) | Vivo X300 Ultra (Rumored) |
|---|---|---|
| Battery Capacity | 6,000mAh | ~7,000mAh (rumored) |
| Wired Charging | 90W | 100W (certified) |
| Wireless Charging | 40W | Unknown |
| Fast Charging Standard | Vivo FlashCharge | 100W USB-PPS |
Rumored Specifications Point to a Powerhouse Device
Beyond the confirmed charging speed, a slew of leaks has painted a picture of a formidable flagship. The most striking rumor suggests the X300 Ultra will feature a dual 200MP camera system. This setup is said to include a large 1/1.12-inch primary sensor and a 1/1.4-inch telephoto sensor, complemented by a 50MP ultrawide camera. For power, it is speculated to house a massive 7,000mAh battery, a substantial increase from its predecessor's 6,000mAh cell. The display is tipped to be a 6.8-inch 2K resolution panel from BOE with a 1-120Hz adaptive refresh rate, while the chipset could shift from MediaTek to Qualcomm's next-generation Snapdragon 8 Elite Gen 5 processor.
Key Rumored Specifications for Vivo X300 Ultra:
- Model Number: V2536A
- Fast Charging: 100W wired (20V/5A, USB-PPS)
- Battery: Rumored 7,000mAh
- Chipset: Qualcomm Snapdragon 8 Elite Gen 5 (rumored)
- Display: 6.8-inch, 2K resolution, 1-120Hz LTPO, BOE panel
- Rear Cameras: Dual 200MP (Primary: 1/1.12", Telephoto: 1/1.4") + 50MP Ultrawide
- Security: 3D ultrasonic fingerprint sensor
- Expected Launch: End of Q1 2026
Context and Comparison with Vivo's Charging History
While 100W charging is impressively fast, it is worth noting that Vivo has demonstrated even more rapid charging technology in the past. As far back as 2019, the company showcased a 120W Super FlashCharge prototype capable of filling a 4,000mAh battery in just 13 minutes. The decision to equip the X300 Ultra with 100W charging, therefore, may represent a balance between cutting-edge speed, thermal management, and battery longevity—especially for a device rumored to have a 7,000mAh capacity. Even at 100W, charging such a large battery from zero to full is estimated to take approximately 25 minutes, which remains exceptionally quick in the current market.
Anticipated Launch Timeline and Global Availability
The Vivo X300 Ultra is not expected to launch imminently. Based on the typical product cycle of its predecessor, the X200 Ultra, which debuted in April 2025, industry observers speculate the X300 Ultra will likely arrive towards the end of the first quarter of 2026. Both of the provided source articles indicate that Vivo plans a global launch for the device, suggesting it will not be confined to the Chinese market. As with all pre-release information, these details should be treated as informed speculation until Vivo makes an official announcement, which will solidify the specifications, features, and final launch date for this highly anticipated flagship.
