Great choice if these matter:
  • Photo / Video

Watch out for:
  • One-Handed Use
  • 232g weight and a camera bump that grows further with the clip-on ZEISS lenses make one-handed use harder.

Main risks
  • One-Handed Use
  • 232g weight and a camera bump that grows further with the clip-on ZEISS lenses make one-handed use harder.
  • Physical buttons were removed in favor of touch-sensitive zones, a change some reviewers find fiddly.
  • OriginOS is a steeper relearning curve for anyone coming from stock Android or a different Chinese skin.
The risk level is computed from the release date and verified weaknesses. The confidence score appears only once enough owner reports exist.

Official Statement

What does Vivo say about the product?

A summary of Vivo's official product description.

Official Vivo source

Vivo positions the X300 Ultra as its ultimate imaging flagship, built around the ZEISS Master Lenses Collection.

Vivo brought its X300 Ultra to global markets for the first time as a full Ultra-tier release, launching in China on March 30, 2026 before expanding internationally. The phone is built around dual 200MP ZEISS sensors, a gimbal-stabilized periscope telephoto and optional clip-on ZEISS lens attachments that Vivo markets toward professional and semi-professional creators.

“The X Series' ultimate imaging flagship, featuring the industry-leading ZEISS Master Lenses Collection.”

GSMArena

Review — 4.7 / 5
“It is unapologetically ambitious, unapologetically expensive and unapologetically camera-centric. And honestly, vivo has earned the right to be confident here because the X300 Ultra delivers on nearly every front that matters in a modern flagship.”

GSMArena calls it one of the best Android flagships currently available and arguably the most complete camera phone yet made, while flagging the removed physical buttons and average speaker quality as its main compromises.

FAQ

The most common questions about this product

What the numbers on the spec sheet actually mean in day-to-day use.

Are the clip-on ZEISS telephoto lenses worth buying separately?
If you regularly shoot distant subjects — wildlife, sports, concerts — yes, the 400mm equivalent reach is genuinely unique to this phone. For everyday photography the built-in 3.7x periscope alone already outclasses most rivals on paper, so the add-on lenses are a niche purchase, not a requirement.
How does removing physical buttons affect everyday use?
Volume and power controls are now touch-sensitive zones along the frame. Most reviewers adapt within a day or two, but it does mean less reliable operation with gloves on or through a thick case — worth testing in person if you rely on tactile buttons.
Is the 6600mAh battery actually better than the OnePlus 15's 7300mAh cell?
In raw capacity, no — the OnePlus 15 is larger. The X300 Ultra's efficient chipset and display tuning may bring endurance close enough that most users won't notice the difference across a normal day, but we have not timed either phone.
