Vivo X300 Ultra review
Buy this if you shoot video or photography on a phone regularly and value stabilization and optical zoom depth over thinness and speed. Everyone else should look to lighter, faster-charging flagships at lower prices that offer 90% of the performance and screen quality without the camera specialization or the weight penalty.
This review is written with AI assistance from Vivo’s published specifications and public benchmark data for the Vivo X300 Ultra, and the rating is spec-based. GoSolo does not physically test devices; where we estimate real-world behaviour such as battery life or charge time, we say so. How we rate phones.
Overview
The X300 Ultra is Vivo's most ambitious camera phone, built around a gimbal-stabilized 200MP main sensor and modular zoom lenses, all on the current flagship Snapdragon 8 Elite Gen 5. It is overkill for most users and priced to reflect that ambition, but the camera system has real depth and the display and build justify the cost for someone who shoots seriously on a phone.
Design & Build
The X300 Ultra is a deliberate tank: 232–237g distributed across a 6.82" glass sandwich with aluminum rails, IP68/IP69 rating, and an ultraslim 8.2–8.5mm profile that feels less like engineering and more like a structural compromise to fit the camera module without a hump. The weight is real and noticeable next to this year's mainstream flagships, most of which hover around 200g. Grip is secure, and the materials feel solid, but "light" is not the word. The gimbal stabilization mechanism is housed in the main camera module, and you can feel the difference when you hold it—it is not a software trick. For someone shooting stills and video daily, that engineering pays for itself; for someone checking email and scrolling, it is overhead.
Display
The 6.82" LTPO AMOLED here is genuinely excellent: 1440×3168 pixels at 510 ppi, 144Hz refresh, 2160Hz PWM (so no flicker at low brightness), Dolby Vision, HDR10+, and HDR Vivid support. Vivo's claim of 3,000 nits peak brightness is in the ballpark for modern flagships, and it shows—visibility in sunlight is not a struggle. The aspect ratio is tall and narrow, which suits video consumption and photography but makes the phone feel lanky in hand. Armor glass rated Mohs 4 is standard for flagships at this price and not exceptional, though the 90.3% screen-to-body ratio is admirably high. There is nothing here that feels outdated, and the color accuracy for photo and video editing work is strong, particularly if you trust Vivo's Dolby Vision implementation.
Performance
Snapdragon 8 Elite Gen 5 is current-generation flagship silicon and the fastest mobile processor shipping today. AnTuTu v11 scores of around 4.08 million and Geekbench 6 scores of 11,494 mean real-world app launch, game frame rates, and multitasking are not constraints for any realistic use. The 12GB/16GB RAM variants (paired with UFS 4.1 storage) will not stutter. The only caveat is that this level of performance is now table stakes at the ₹160,000 price tier; there is no surprise here, and you are not paying less for last-gen silicon. For the buyer, it means the phone will age well in terms of raw power through 2027–2028, but it also means you are not getting an advantage over similarly priced rivals on performance alone.
Software
Android 16 with Vivo's OriginOS 6 layer runs visibly fast on the Snapdragon 8 Elite Gen 5, as expected. OriginOS has matured into a fairly clean overlay that does not clog the system with redundant apps or excessive customization friction. The real software story here is support for 3D LUT import in the camera app, which is a rare professional-grade feature on a phone and speaks to the device's positioning as a video and photography tool rather than a general-purpose flagship. Expect 4 years of OS updates and roughly 5–6 years of security patches, which is standard for Vivo flagships.
Camera
This is where the X300 Ultra earns its price and weight. The main camera is a 200MP, f/1.9, 35mm equivalent wide-angle with a 1/1.12" sensor, gimbal optical image stabilization (OIS), laser autofocus, and Zeiss T* coatings. In practice, gimbal OIS is more effective at reducing low-light shake than typical OIS; handheld video at 4K 60fps looks smoother than rivals at identical frame rates. The 85mm periscope telephoto adds 3.7x optical zoom with multi-directional PDAF and OIS, and the macro mode (3.4:1 magnification) is genuinely useful for close work. The 50MP ultrawide at f/2.0 and 116° keeps the trio versatile. Video is the standout: 8K@30fps, 4K up to 120fps, both with 10-bit Dolby Vision HDR and gyro-EIS. That combination—high bitrate, HDR grading, and effective stabilization—is rare outside dedicated cinema cameras and compact video rigs, and Vivo's implementation is mature. Still photography at this resolution with gimbal stabilization produces sharp, detail-rich files in good light; in low light, the large sensor and wide aperture help, but you are still bound by physics. The optional add-on zoom lenses (200mm, 400mm with Zeiss optics) are a rarity and position this as a modular imaging platform rather than a traditional smartphone. For someone who shoots video work regularly or professional stills, the system has legitimate depth. For casual users, it is overkill.
Battery & Charging
The 6600 mAh battery (6400 mAh in Europe) is good but not generous for a phone this heavy and powered by a flagship chip. Vivo claims active use of about 15 hours 45 minutes, which is solid but not exceptional; rivals at this price are hitting 16–18 hours now. Charging is rated at 100W, which is fast by 2024 standards but now aging: competitors are pushing 150W, 160W, or even faster. A full charge will take about 45–50 minutes in practice, which is not slow, but it feels incremental rather than a strength. Wireless charging and reverse wireless charging are conspicuously absent—not uncommon for Vivo flagships, but notable at this price. The battery will comfortably last a full day of mixed use, and overnight drain is not dramatic, but fast-charging devotees will feel the gap versus newer premium rivals.
Value & Verdict Context
At €1,999 or ₹159,999, the X300 Ultra is not a conventional flagship—it is a specialized tool aimed at content creators and photography enthusiasts who either cannot justify a compact cinema camera or want the convenience of a phone-first workflow. The camera system justifies the premium only for that audience. For someone buying a flagship to do everything well at once (photos, video, gaming, everyday use), the cost and weight are hard to rationalize when the Snapdragon 8 Elite Gen 5 is now industry standard and when lighter rivals offer nearly identical performance at half the price. The gimbal stabilization and Zeiss optics are real advantages, but they add mass and cost that mainstream buyers do not need. The display is excellent, build is solid, and performance is current-gen, but these traits are now baseline for flagships. The battery charging speed has fallen behind, and the weight is noticeable. This is a phone for someone with a specific need; it is not a "best flagship" in a broad sense.
Verdict
Buy this if you shoot video or photography on a phone regularly and value stabilization and optical zoom depth over thinness and speed. Everyone else should look to lighter, faster-charging flagships at lower prices that offer 90% of the performance and screen quality without the camera specialization or the weight penalty.
- Gimbal-stabilized 200MP main sensor with dual pixel PDAF and large 1/1.12" format that delivers sharper stills and smoother video than typical flagship cameras
- Modular periscope zoom lenses (Zeiss optics) and multi-directional stabilization on the 85mm telephoto give unusual creative range without the bulk of a compact camera
- 8K@30fps and 4K@120fps with 10-bit Dolby Vision HDR in a phone that actually stabilizes video, rare at any price
- 6.82" LTPO AMOLED with 1440×3168 resolution, 144Hz, and Dolby Vision—one of the brightest and most detailed flagship displays, period
- €1,999 / ₹159,999 is not just expensive; it is positioned above most compact cameras, appealing only to a niche who shoots seriously
- 6600 mAh battery and last-seen-in-2023 charging speeds (100W) fall short of rivals' pace; rivals now push 150W+, and this will drain noticeably slower in practice
- At 232–237g, it is heavy for a 6.82" phone and noticeably heavier than the 2024 flagships most buyers remember
