Vivo is set to release a new smartphone model, the Vivo X300s, which promises significant improvements in battery capacity and processing power. Recent leaks reveal that this device will come equipped with a massive 7,000 mAh battery and the powerful Dimensity 9500 Plus chipset. These features position the Vivo X300s as a notable upgrade from its predecessor, the Vivo X300, which debuted in October 2025.
This new model aims to meet the needs of users seeking a premium smartphone that combines long-lasting battery life with advanced performance. The enhancements suggest that Vivo is targeting heavy users and tech enthusiasts who prioritize endurance and speed in one device.
Revolutionary Battery Capacity
One of the standout features of the Vivo X300s is its extraordinary 7,000 mAh battery. This capacity is well above the current flagship standards, exceeding the Vivo X300’s 6,040 mAh and the X300 Pro’s 6,510 mAh batteries. Such a jump indicates Vivo’s focus on delivering extended usage times without frequent recharging.
Industry analysts predict that this large battery could allow the Vivo X300s to last well beyond a full day of intensive use. For moderate users, the phone might even stretch to two days on a single charge. This battery life potential could redefine expectations for premium smartphone endurance and distinguish the Vivo X300s within its competitive segment.
Powerful Performance with Dimensity 9500 Plus
The Vivo X300s will be powered by the Dimensity 9500 Plus chipset, an overclocked variant of the standard Dimensity 9500. Manufactured using TSMC’s advanced N3P process, this chip offers significant performance gains. Its CPU comprises one Arm C1-Ultra core, three Arm C1-Premium cores, and four Arm C1-Pro cores, alongside support for the latest SME2 instructions. This makes the device capable of accelerated AI processing.
Graphically, the Dimensity 9500 Plus integrates the Arm Mali-G710 Ultra GPU. This GPU is announced to deliver a 33% improvement in graphics performance and a 119% boost in ray tracing capacities compared to previous generations. The device is also equipped with a second-generation Neural Processing Unit (NPU) 990, capable of processing up to 100 TOPS (Trillions of Operations Per Second), enhancing AI-driven tasks’ responsiveness and smoothness.
Additional Specifications Revealed
Besides its battery and processor, the Vivo X300s includes several other premium features. The phone is expected to feature a 6.78-inch flat OLED display with a 1.5K resolution. The screen is designed with ultra-thin and symmetrical bezels on all sides to maximize the immersive viewing experience.
Photography capabilities have also been elevated. The main camera is rumored to have a massive 200-megapixel sensor, paired with a mid-range periscope telephoto lens to provide substantial zoom functionality. Other high-end attributes include an under-display ultrasonic fingerprint sensor and a waterproof chassis, contributing to the device’s overall premium feel.
Launch Expectations and Market Position
Vivo plans to launch the X300s in March 2026, possibly alongside the Vivo X300 Ultra flagship model. The initial release is expected to happen in the Chinese market, following Vivo’s typical rollout strategy for its flagship series. As an enhanced version of the Vivo X300, the X300s targets premium users who value cutting-edge technology in terms of battery life and processing power.
This leak confirms Vivo’s ongoing commitment to innovation in the highly competitive smartphone market. With a giant 7,000 mAh battery and the high-performance Dimensity 9500 Plus chip, the Vivo X300s promises to be a compelling choice for users prioritizing endurance and efficiency. More detailed official information is anticipated as the launch date draws closer.
