Vivo is preparing to launch this new flagship smartphone with a strong focus on long battery life, high-end camera capabilities and smooth gaming performance.

Leaks and official teasers suggest that the device could debut in China later this month before expanding to other markets, including India. Early details indicate that the phone will feature a massive battery, a powerful processor and a high-refresh-rate display designed for gaming and multimedia.

While Vivo has not yet revealed every detail about the device, several key specifications have already surfaced through company announcements and industry leaks. Here is everything currently known about the upcoming smartphone.

Vivo X300s Launch Date & Availability (Expected)

Reports suggest that the Vivo X300s will launch in China around March 30, 2026, alongside other models from the X300 series. The company has not officially confirmed the global rollout timeline yet.

However, industry insiders believe the smartphone could reach other markets soon after its China debut. India is expected to be one of the next regions to receive the device, possibly between mid-April and late April 2026.

Vivo has previously followed a similar strategy with earlier X-series models by launching them first in China and then gradually expanding to global markets.

Vivo X300s Specifications & Performance (Expected)

The upcoming flagship smartphone is expected to deliver significant upgrades in performance and display technology.

According to early information, the Vivo X300s will feature a 6.78-inch BOE Q10 Plus display with a 144Hz refresh rate, which could make it one of the first X-series smartphones to support such a high refresh rate. The display also uses circular polarisation technology designed to improve eye comfort during long screen sessions.

The smartphone may also support native 144 FPS gameplay for certain MOBA games, indicating that Vivo is targeting mobile gamers with this device.

In terms of processing power, the device is expected to run on the MediaTek Dimensity 9500 chipset, a flagship processor designed to deliver strong gaming performance, multitasking capabilities and improved power efficiency.

The phone may also include enhanced stereo speakers and a stronger vibration motor to improve the gaming experience.

Vivo X300s Camera Features (Expected)

Camera performance remains a major highlight of Vivo's flagship smartphones, and the Vivo X300s is expected to continue that tradition. The device will reportedly feature a 200-megapixel Zeiss-tuned primary camera, designed to capture highly detailed photos with improved colour accuracy and dynamic range.

Leaks also suggest that the smartphone may include a triple-camera setup, potentially featuring:

• 200MP main camera
• 50MP periscope telephoto lens
• 50MP ultra-wide camera

The camera system is expected to be part of Vivo's advanced imaging platform aimed at improving both photography and video recording.

Vivo X300s Battery & Charging Technology (Expected)

Battery life appears to be one of the biggest highlights of the upcoming smartphone. Company executives have confirmed that the Vivo X300s will feature a massive 7100mAh battery, the largest capacity ever seen in the X-series lineup. The battery uses fourth-generation silicon-anode technology, which increases energy density while maintaining long-term durability.

The device also introduces an updated charging feature called Global Direct Drive Power Supply 2.0. This system can deliver power directly from the charger to the device during activities such as gaming or video streaming. By bypassing the battery during heavy use, the system helps reduce battery stress and heat generation.

Vivo X300s: Price in India (Expected)

While Vivo has not officially confirmed the price yet, leaks suggest that the smartphone could fall in the premium flagship category. The expected price of the Vivo X300s in India may range between ₹74,999 and ₹79,999, depending on storage variants and configuration.

If these estimates prove accurate, the device will compete directly with other premium Android smartphones in the same price segment.

Vivo X300s: What to Expect?

The Vivo X300s appears to be designed for users who want strong performance, long battery life and flagship camera features in one device. With a large battery, 200MP Zeiss camera, powerful chipset and high-refresh-rate display, the phone could attract gamers, photographers and power users alike.

However, many specifications and pricing details remain unofficial for now. The complete picture will become clearer once Vivo officially unveils the device at its launch event later this month.
