I was keeping a close eye on the chaos at MWC 2026 in Barcelona, and while everyone was busy hunting for the Vivo X300 Ultra, Vivo sneakily let another beast out of the bag. It looks like the rumored Vivo X300 Max made a “quiet” appearance during a MediaTek presentation, and honestly, it might actually steal the spotlight from its Ultra sibling.
We’ve seen leaks from industry insiders like Roland Quandt and even some teaser shots from Vivo executives on Weibo, all pointing toward a massive hardware shift that makes this more than just another iterative update.
Design and Visual Intelligence
The first thing you’ll notice about the X300 Max—carrying the model number V2548A—is that Vivo isn’t walking away from its powerhouse partnership with Zeiss. The rear camera module keeps that iconic branding front and center, flanked by at least three massive lenses.
What’s really cool here isn’t just the glass, though; Vivo’s Han Bo Xiao hinted at a brand-new AI-powered imaging system. By pairing the custom V3+ chip with MediaTek’s latest silicon, the phone aims to automate the “pro” parts of photography. If this works as promised, you won’t need to be a shutterbug to get magazine-quality shots; the AI handles the heavy lifting of light balancing and focus in real-time.
Performance and Endurance
Under the hood, this thing is shaping up to be a performance monster. It’s set to run on the MediaTek Dimensity 9500, which explains why it was spotted at their booth. But the real “mic drop” moment for me is the battery.
We are looking at a rumored 7,000mAh capacity, which is frankly absurd for a phone that still looks this sleek. To keep that massive cell from taking all day to juice up, 3C certification filings have already confirmed 90W wired charging.
-
Display: 6.78-inch LTPO OLED with a crisp 1440p resolution.
-
Processor: MediaTek Dimensity 9500 paired with Vivo’s V3+ imaging chip.
-
Battery: 7,000mAh with 90W fast charging support.
While the X300 Ultra is the one getting the big marketing push for its China launch later this month, the X300 Max feels like the “real world” champion for users who care about two things: a screen that doesn’t quit and a camera that thinks for you. If these specs hold up for the global rollout later this year, it’s going to be a very tough handset to beat.
