vivo X300 Ultra: Full Specifications, Features & Review (2026)

Overview

The vivo X300 Ultra is an unusually camera-centric 2026 flagship that treats mobile photography as the primary design objective rather than a secondary feature. Its imaging system combines three ZEISS master lenses covering 14mm ultra-wide, 35mm documentary and 85mm telephoto perspectives, with 200MP sensors at both the 35mm and 85mm positions. The 50MP ultra-wide uses a large Sony LYTIA 818 sensor, while the telephoto system adds CIPA-rated gimbal-grade stabilization and compatibility with optional 200mm and 400mm-equivalent ZEISS telephoto extenders. Beyond imaging, the Snapdragon 8 Elite Gen 5 platform, 6.82-inch 144Hz AMOLED display, UFS 4.1 storage and 6600mAh battery make the X300 Ultra a complete flagship rather than a specialist camera phone. Its strongest audience is photographers, filmmakers and creators who value focal-length flexibility, high-resolution capture and advanced video controls.

Key Highlights

• Dual 200MP ZEISS imaging system: The 35mm documentary camera and 85mm gimbal-grade APO telephoto both use 200MP sensors, giving the X300 Ultra unusually high native resolution across two important focal lengths.
• Professional video workflow: The phone supports multi-focal 4K 120fps recording with 10-bit Log, Dolby Vision, APV and ACES-oriented workflows, making it particularly relevant to mobile filmmakers and creators.
• Large battery and fast charging: A 6600mAh battery is paired with 100W wired and 40W wireless charging, giving the device a stronger endurance and charging specification than many conventional flagship phones.

Price in US

The X300 Ultra does not have a conventional vivo US MSRP published on its official product specification page. The US pricing references above therefore represent USD-equivalent values derived from verified launch pricing rather than invented US MSRP figures. Actual imported US retail pricing can be higher because of retailer margins, shipping, taxes, warranty coverage and regional configuration differences. The base international commercial listing is currently around $1,199, while the official configuration ladder places higher-memory versions above the entry model.

Our Take

The vivo X300 Ultra is one of the most ambitious camera-focused smartphones of 2026. Its biggest advantage is not simply the 200MP headline number; it is the combination of large sensors, three useful focal lengths, ZEISS optics, stabilization and a serious video pipeline. The optional 200mm and 400mm-equivalent extenders further push it toward dedicated-camera territory. The trade-offs are substantial weight, no microSD expansion, no 3.5mm headphone jack and regional availability considerations. For photographers and creators, it is an exceptional flagship. For buyers who mainly want mainstream US carrier support and a mature ecosystem, Samsung's Galaxy S26 Ultra remains the easier purchase.
