Every few years, a phone comes along that makes the current "flagships" look a little bit like toys. If the latest spec leaks are anything to go by, the vivo X300 Ultra is that phone for 2026. While competitors are shaving off millimeters and focusing on AI gimmicks, vivo seems to be building a literal tank of a smartphone. The leaked hardware for model V2562 seems very interesting if you ask me. Just read below and you'll get the point:

vivo X300 Ultra - Key Specs

  • Dual 200MP System: Features high-resolution Sony and Samsung sensors for the main and periscope cameras.
  • Continuous Optical Zoom: Enables smooth, gapless zooming transitions for professional-grade video.
  • 7,000mAh Battery: A major capacity upgrade using high-density battery technology.
  • Snapdragon 8 Elite: Powered by the Gen 5 chipset for industry-leading efficiency and speed.
  • Rugged Certification: Boasts an IP69 rating, offering superior resistance to dust and water.

Redefining the Mobile Lens

The conversation starts and ends with those cameras. We aren't just looking at a high megapixel count for the sake of marketing. The leak points to a dual 200MP setup, featuring a Sony LYT901 for primary duties and a Samsung HPB for the periscope.
In my view, the most exciting part is the continuous optical zoom. Most phones feel "clunky" when you zoom in because they are just switching between fixed lenses. If vivo has actually managed to fit a moving optical zoom assembly into a chassis this size, it changes the game for mobile video. Combined with a 5MP multi-spectral sensor to nail those tricky skin tones, this looks more like a Zeiss camera that happens to run Android than a standard phone.

Breaking the 5,000mAh Ceiling

We have been stuck with 5,000mAh batteries for way too long. To see vivo reportedly jumping straight to a 7,000mAh battery is a huge relief for anyone who actually uses their phone for more than just checking emails. Even with the power-hungry Snapdragon 8 Elite Gen 5 and a massive 2K display, this should easily be a two-day phone for most people.
I’m particularly impressed that they kept the IP69 rating. That isn't your standard "dropped it in the sink" protection; it's built to withstand high-pressure, high-temperature water jets. It feels like vivo is making a device for the extreme enthusiast—someone who is going to be out in the wild taking 200MP photos in a rainstorm.

A Heavyweight Contender

The only catch? This hardware isn't light. Between the massive battery and the complex optics, the X300 Ultra is likely going to be a heavy device. But for the person who wants a 2.6k nit Samsung M14 display and the best zoom in the business, a little extra weight in the pocket is a fair trade.
