Vivo X300s Teased With 7,100mAh Battery, Ultrasonic Fingerprint Sensor, and Enhanced Gaming Features

The Vivo X300s has been officially teased by Vivo ahead of its upcoming launch in China, with the company confirming several important hardware upgrades. The smartphone is expected to arrive as a powerful addition to the Vivo X series, focusing on long battery life, improved cooling, and enhanced performance. Earlier rumours suggested the device could launch as the Vivo X300 Max, but recent confirmations indicate the handset will debut under the Vivo X300s name instead.
One of the biggest highlights of the upcoming device is its massive 7,100mAh “Blue Ocean Battery.” Vivo has confirmed that the battery uses fourth-generation silicon-anode technology, which allows the phone to pack a larger capacity without significantly increasing the device’s size. According to the company, this will be the largest battery ever included in a Vivo X series smartphone, promising extended usage for both everyday tasks and heavy workloads.
To support intensive performance, the Vivo X300s will also introduce an upgraded Ice Pulse Fluid VC cooling system. This system includes a larger vapour chamber heat-dissipation plate, designed to manage heat more efficiently during demanding activities such as gaming, video recording, and multitasking. Improved cooling helps maintain stable performance while preventing the device from overheating during long gaming sessions.
In addition to battery and cooling improvements, the handset is expected to offer several gaming optimisation features that enhance responsiveness and system stability. Vivo has also confirmed the inclusion of an ultrasonic fingerprint scanner, which typically provides faster and more accurate unlocking compared to traditional optical sensors. With these upgrades, the Vivo X300s is shaping up to be a performance-focused smartphone aimed at users who want powerful hardware combined with long battery endurance.
