Vivo has officially pulled back the curtain on one of its most anticipated smartphones of the year. The Vivo X300s — a device that spent weeks circulating under the rumoured name “X300 Max” — has now been confirmed by the company itself, complete with a handful of headline specifications that position it as a serious contender in the premium Android segment.
Vivo has confirmed that it will soon unveil the X300s in China, with the confirmation coming from Vivo’s Product Manager Han Boxiao, who shared the details on Weibo. The announcement clears up weeks of speculation and puts a proper name and spec sheet to what many in the tech community already suspected was coming.
What Does the “S” Actually Stand For?
Vivo’s product manager confirmed that the “s” stands for “SuperMax,” highlighting improvements across multiple areas, particularly performance. The company had internally discussed naming the device the X300 Max due to the scale of its upgrades, but eventually chose to keep the “s” naming convention, consistent with previous X-series refresh models.
The positioning is deliberate. The X300s is aimed at users who want a large-screen flagship without compromising on imaging — combining a bigger screen with strong camera capabilities at a time when many imaging-focused phones have shifted toward compact displays.
Display: A First for the X Series
The Vivo X300s will feature a flat 6.78-inch AMOLED display using a BOE Q10+ panel, supporting a 144Hz refresh rate, 1.5K resolution, and Circular Polarization Light 2.0 technology, which is said to offer improved eye protection.
This makes it the first Vivo X series smartphone to feature a 144Hz refresh rate — the X300 and X300 Pro both top out at 120Hz. The display will also support Zeiss colour calibration, bringing the same colour science the brand applies to its cameras into the viewing experience. The phone is also said to support native 144FPS gameplay in certain MOBA titles.
Camera: 200MP Zeiss Main Sensor
The camera system is where Vivo is making the boldest claims. Boxiao confirmed that the device will feature a 200MP ZEISS camera system, though the rest of the camera details remain under wraps for now.
What leaks have filled in is encouraging. The X300s is expected to include a 50MP periscope telephoto camera and a 50MP ultrawide lens, with all three cameras backed by Zeiss optics. That triple-camera configuration — anchored by a 200MP primary shooter — would make the X300s one of the most capable imaging devices in its class when it launches.
Performance and Chipset
The Vivo X300s is expected to use the MediaTek Dimensity 9500 chip paired with LPDDR5X RAM and UFS 4.1 storage — a combination that represents the top of what Android silicon currently offers. The Dimensity 9500, which powers several flagship devices in early 2026, delivers strong multi-core performance while keeping thermal output in check during sustained workloads like gaming and 4K video recording.
Battery: 7,000mAh With Fast Charging
The phone will pack a 7,000mAh silicon carbon battery with 90W wired and 40W wireless fast charging support. At 7,000mAh, the X300s would carry one of the largest batteries in the flagship segment — a meaningful differentiator for users who prioritise endurance alongside performance.
Audio and Haptics: Gaming-Grade Upgrades
Vivo has put an unusual amount of emphasis on audio and haptics with this device. The X300s will be equipped with dual 1511 symmetric speakers and support the Super-sense Gaming Audio Zone feature, which Vivo claims can improve in-game audio detail by up to 120%. The practical effect, according to the company, is that directional audio cues in games — footsteps, gunfire, environmental sounds — become significantly easier to locate and distinguish.
The phone will also include a large customised 4D vibration motor designed to deliver stronger and more detailed haptic feedback, said to support enhanced vibration effects in more than ten popular mobile games. Vivo describes it as the largest and most powerful vibration motor ever included in an X-series device.
Software and Durability
The Vivo X300s will run OriginOS 6 based on Android 16. On the durability front, the device is expected to carry an IP68 and IP69 rating for water and dust resistance — dual certification that covers both prolonged submersion and high-pressure water jets.
Launch Timeline
The Vivo X300s is expected to debut alongside the Vivo X300 Ultra later this month in China, though no concrete release date has been announced. A global rollout is anticipated to follow, though Vivo has not yet confirmed regional availability or pricing.
What is clear is that the X300s is no minor refresh. With a 200MP Zeiss camera, the X series’ first 144Hz panel, a 7,000mAh battery, and Dimensity 9500 internals, Vivo is positioning this as a device that competes directly with the best large-screen flagships on the market in 2026.
