Vivo X300s Advanced Imaging and V3+ Proprietary Chip

A primary highlight of the Vivo X300s is its photography architecture, which utilizes Vivo’s in-house V3+ imaging chip to enhance data processing for photos and videos. The rear camera system is expected to lead with a 200-megapixel primary sensor featuring Optical Image Stabilisation (OIS). This is reportedly supported by a 50-megapixel ultra-wide lens and a 50-megapixel periscope telephoto camera, also equipped with OIS.

For front-facing tasks, the device is said to house a 50-megapixel sensor. The integration of Zeiss optics across the camera module suggests that Vivo is continuing its partnership to provide high-fidelity colour accuracy and lens clarity for mobile photographers.

Vivo X300s Charging Capabilities and Durability Standards

In terms of power delivery, the Vivo X300s is expected to support 90W wired fast charging and 40W wireless charging. This combination aims to provide rapid replenishment for the large 7,100mAh cell. The hardware suite is rounded out by an ultrasonic in-display fingerprint sensor for biometrics and a USB-C Gen 3.2 port for high-speed data transfers.

The leaked promotional materials confirm that the Vivo X300s will be available in four distinct colour finishes: light green, lavender, white, and dark grey. To ensure longevity, the chassis is expected to carry both IP68 and IP69 ratings, providing high resistance against dust and water ingress, including high-pressure water jets. Realme Narzo 100 Lite India Launch Imminent; Check Leaked Specifications.
