Almost six months after the launch of the vivo X300 and X300 Pro, the Chinese smartphone giant finally unleashes the much-awaited X300 Ultra.

Ultra-impressive camera system

First and foremost, its improved cameras.

Unlike its Pro sibling, the X300 Ultra follows the same configuration as last year’s X200 Ultra. It uses 35mm as its standard focal length instead of the usual 24mm found on most (if not all) smartphones.

This means the main sensor is locked in at a minimum of 1.5x. Still, it’s been upgraded from 50MP to a whopping 200MP f/1.85 based on a large 1/1.18-inch Sony LYT-901 image sensor.

Meanwhile, shooting at “1x” relies on its 50MP f/2.0 ultra-wide lens based on the 1/1.28-inch Sony LYT-818. While it’s the same as last year’s X200 Ultra, it’s still considerably bigger and better among newer phones in its league.

Definitively, the X300 Ultra also boasts a newer 200MP f/2.67 periscope telephoto shooter using Samsung’s 1/1.4-inch ISOCELL HP0. Optical zoom distance still starts at 3.5x (85mm equivalent) which is similar to the X300 Pro and X200 Ultra.

If that isn’t enough, vivo announces not one, but two new teleconverter lenses.

The all-new 400mm G2 Ultra ZEISS Telephoto Extender lens is the longest one in a smartphone so far. Still, vivo has achieved to make it as compact as possible — a tad longer than the former 200mm add-on lens in the X200 Ultra and X300 Pro.

There’s also the upgraded G2 ZEISS Telephoto Extender. It’s shorter and smaller compared to previous generation and comparable to a size of a lipstick (around 96mm in length).

This means better portability while trying to shoot subjects from afar with the same 200mm focal length.

Additionally, the vivo X300 Ultra also has a 5MP f/2.45 multi-spectral sensor that other X300 phones lack. This is basically responsible for making colors more accurate by capturing a wider range of light beyond the usual RGB color spectrum.

Ultra-grade video shooter

One of the highlights of the vivo X300 Ultra focuses on its video shooting prowess that targets Apple’s iPhone 17 Pro Max.

For one, its ultra-wide camera has OIS built-in — a feature often overlooked by other phone makers.

OIS is also enabled when using the said teleconverter lenses.

Other than that, the X300 Ultra is capable of shooting in both 4K/120fps Dolby Vision and 4K/120fps 10-bit LOG support.

This means prospective users can finally apply LUTs in post (or 3D LUTs in the phone) — much like how videographers and cinematographers do when shooting with their expensive mirrorless cameras.

Even though 10-bit LOG has been around in the recent vivo flagships, only the X300 Ultra can seamlessly switch between all focal lengths while LOG recording is enabled.

In line with these, the vivo X300 Ultra also features a new Professional Video Mode in its native camera app.

Ultra-powerful flagship

The vivo X300 Ultra brings some subtle improvements over the former X200 Ultra flagship.

While they both share the same 6.82-inch 8T LTPO AMOLED 2K display, the X300 Ultra has a faster 144Hz refresh rate support versus 120Hz. It’s also now an Ultra XDR screen, thanks to the improved BOE Q10 Plus panel.

Most of all, the X300 Ultra runs the latest 3nm Qualcomm Snapdragon 8 Elite Gen 5 SoC. Despite the shortage of components, the X300 Ultra relies on a speedy UFS 4.1 storage standard while memory is even faster with LPDDR5X Ultra (and Ultra Pro) protocol.

Shockingly though, battery hasn’t been bumped by a lot as the X300 Ultra is only equipped with a 6600mAh battery. While that’s 600mAh more than its predecessor, it’s merely a 90mAh gap versus its Pro sibling.

That slight boost is the same with its wired charging speeds from 90W to 100W FlashCharge.

The Ultra s-idekick

Other than the X300 Ultra, the vivo X300s is also present in the scene. This is a follow-up to last year’s X200s.

It runs MediaTek’s Dimensity 9500 SoC like the vanilla X300 but with a bigger 7100mAh battery (versus 6040mAh). That’s a lot bigger than what the X300 Ultra possesses.

However, the vivo X300s borrows that same 6.78-inch display size as the X300 Pro. This also marks as a departure from that 6.67-inch sweet-spot screen size of the X200s and the “smaller” 6.31-incher X300.

Cameras are quite indifferent as of the X300. A 200MP main camera based on Samsung ISOCELL HPB with Sony’s LYT-602 sensor for its telephoto module. The improvement though can be seen when using the camera app.

vivo’s new Blueprint Palette lets you choose a color in a swatch board and save it as a recipe. The user can also adjust settings in real-time — letting you see the look of the image during preview even before hitting the shutter release. The same feat is also found on the X300 Ultra.

And, much like the base X300, the vivo X300s is capable of attaching that 200mm teleconverter lens with its own camera kit — something the X200s cannot achieve at all.

As teased way back in MWC 2026, the X300 Ultra is vivo’s first Ultra smartphone to be sold globally. We’ll just have to wait and see which regions will have it.
