Details about the upcoming Vivo X300 Ultra have surfaced ahead of its expected debut in early 2026, revealing key information about its battery and charging capabilities. According to recent leaks and certification listings, the X300 Ultra is set to feature a large battery and fast wired charging support, indicating that Vivo is aiming to improve endurance and recharging speeds over previous models.
The phone has appeared in regulatory certification with support for 100W wired charging, suggesting it will benefit from rapid power delivery. This fast charging standard will allow the battery to recharge quickly, keeping the device competitive with other flagship smartphones. Alongside this, leaks suggest the X300 Ultra could be equipped with a battery close to 7,000mAh in capacity, making it one of the larger batteries seen in a Vivo flagship. The combination of high capacity and fast charging could result in significantly long usage times between charges.
The new flagship is also expected to launch with upgrades in other areas, including a powerful Snapdragon 8 Elite Gen 5 chipset and an advanced camera system. With these enhancements, the Vivo X300 Ultra aims to offer strong performance, long battery life, and fast recharging for users when it officially launches in the first quarter of 2026.
