Vivo’s X300 Ultra pushes beyond the X300 Pro with a stronger camera setup, a 6,600 mAh battery and a sharper 6.8-inch AMOLED screen.
The display rises to 3168x1440 resolution at 510 ppi while keeping a 144 Hz refresh rate and the same 4,500-nit peak brightness rating as the prior model.
Design changes are modest: the phone keeps the beveled aluminum frame and matte glass back, but drops the Shortcut Button seen on the X300 Pro.
Inside the box, Vivo includes the phone, SIM tool and case, while the 100 W charger and cable are sold or bundled depending on region.
The review frames the Ultra as an incremental but meaningful step up—especially for camera-focused buyers—even if the gains may be hard to justify for every wallet.
With rivals offering 10,000mAh batteries, is Vivo's 'Imaging + AI' strategy enough for the X300 Ultra to compete?
Beyond its camera, what 'Agent phone' features prove Vivo's AI vision is more than just marketing?
