Vivo is back in the spotlight, and this time, it’s the Vivo X300 Ultra grabbing all the attention. While Vivo hasn’t officially confirmed anything yet, recent leaks are painting a pretty exciting picture. From a massive 7,000mAh battery to flagship specs and a launch window that’s just around the corner — here’s everything we know so far.
Timeline
According to a leak on Weibo from reliable tipster Smart Pikachu, the Vivo X300 Ultra is expected to launch in China in Q1 2026, which means between January and March. That’s slightly ahead of the previous Ultra model — the Vivo X200 Ultra — which debuted in April 2025.
This timing also makes sense when you look at the brand’s recent trend. The Vivo X300 and X300 Pro launched in October 2025, similar to their X200-series predecessors. An early 2026 release for the Ultra variant fits neatly into that pattern.
Battery
One of the biggest highlights? A massive 7,000mAh battery — yes, you read that right.
This would be a 1,000mAh boost over the 6,000mAh battery found in the X200 Ultra, and it’s also larger than the batteries in the X300 (6,040mAh) and X300 Pro (6,510mAh). If true, this could make the X300 Ultra one of the highest-capacity premium flagships on the market.
Paired with 90W wired and 40W wireless charging, this device might just deliver multi-day battery life — a game-changer for power users and mobile gamers alike.
Specs
The leaks didn’t stop at the battery. Here’s what else we’ve learned about the X300 Ultra:
| Spec | Details |
|---|---|
| Processor | Snapdragon 8 Gen 5 (3nm, Elite variant) |
| Display | 6.8-inch 2K AMOLED |
| Rear Cameras | Triple setup with two 200MP sensors |
| Sensor Type | Sony LYTIA 901 (rumoured) |
| Camera Features | Upgraded ultrawide, primary, and 35mm periscope lens |
| Charging | 90W wired, 40W wireless (expected) |
Vivo is clearly going all-in on imaging, which has been their strength for years. The dual 200MP sensor setup, especially if it includes Sony’s LYTIA 901, could push mobile photography to a whole new level.
Also, the inclusion of a 35mm periscope telephoto lens would offer a versatile zoom range, likely better than the X200 Ultra. This makes the X300 Ultra a potential powerhouse for smartphone photographers.
Performance
With Qualcomm’s Snapdragon 8 Gen 5 under the hood — reportedly built on a 3nm process — the Vivo X300 Ultra is expected to be one of the most powerful Android phones of 2026. If this Elite version of the chipset comes with improved thermal efficiency and power management, that giant battery will last even longer.
Gaming, multitasking, video editing, or running AI tasks? This phone should handle all of it with ease.
Design
While the leaks haven’t given us an exact image of the X300 Ultra, expect a design language consistent with the X300 and X300 Pro — sleek curves, ultra-slim bezels, and a clean rear camera module. Vivo tends to go premium with its Ultra models, so we may see glass-metal construction, IP ratings, and premium material choices.
Expectations
Here’s a quick comparison table based on the leaked info vs its predecessor:
| Feature | X300 Ultra (Leaked) | X200 Ultra |
|---|---|---|
| Battery | 7,000mAh | 6,000mAh |
| Cameras | Dual 200MP + 35mm tele | Single 200MP |
| Processor | Snapdragon 8 Gen 5 | Snapdragon 8 Gen 3 |
| Display | 6.8-inch 2K AMOLED | 6.78-inch 2K AMOLED |
| Charging | 90W Wired / 40W Wireless | Same |
If these leaks are accurate, the X300 Ultra is shaping up to be one of the most capable Android flagships to look out for in early 2026. With big upgrades in battery, camera, and processing power, it’s going to be hard to ignore — especially for content creators and tech enthusiasts.
