Vivo X300 Pro Review: The Best Zoom Camera on Any Phone

Camera-first flagships usually mean one standout lens and a couple of afterthoughts bolted on beside it. The Vivo X300 Pro doesn't work that way. Its 200MP Zeiss-tuned periscope telephoto is the headline, but the main sensor, the chip, and the charging system are all genuinely flagship-grade too — this is less a camera phone with compromises elsewhere and more a proper all-rounder that happens to have an exceptional zoom lens. It also has a real, disclosed regional wrinkle worth knowing before you buy: battery capacity varies sharply depending on where you live, a genuine trade-off this review covers honestly rather than glossing over in favour of the headline camera story.

Design and Build

At 226g and 161.2 x 75.5 x 8.0mm, the X300 Pro is a substantial phone but not an unwieldy one — vivo has kept the camera housing reasonably flat despite packing in three lenses and a periscope prism behind it. Build quality is what you'd expect at this price: an aluminium frame and Diamond Armor Glass on the front, backed by dual IP68/IP69 certification against both submersion and high-pressure water jets — a genuinely more thorough rating than the IP68-only certification some rivals still settle for. It's a handsome, understated phone in any of its four launch colours — Phantom Black, Mist Blue, Dune Brown, and Cloud White — with none of the gaudy camera-bump theatrics some rivals go for. The one honest compromise that comes with that camera housing is weight: at 226g, this isn't a phone that disappears in the pocket, a real, physical trade-off for packing in a periscope prism this capable rather than an accident of manufacturing.

Display

The 6.78-inch LTPO OLED panel uses an 8T backplane under Diamond Armor Glass, running at QHD+ resolution (1260 x 2800) with adaptive refresh from 1Hz up to 120Hz. vivo's own marketing claims a 4,500-nit peak, but GSMArena's independent lab testing found real-world figures well short of that: over 2,100 nits for a 75% white swatch in auto mode, and a little over 2,600 nits at a 10% window — both genuinely impressive results in their own right, even if the gap to the marketed figure is worth knowing about before you take the spec sheet at face value. In practice that still means a screen bright enough to stay legible in direct sun without hunting for shade. HDR10+ and Dolby Vision are both supported, and colour accuracy out of the box is excellent. There's nothing experimental about the panel technology here; it's simply one of the best-measured displays on the market right now, marketing-figure gap notwithstanding.

Camera

This is why the X300 Pro exists. The 50MP Sony LYT-828 main sensor, at 1/1.28" with an f/1.57 aperture and OIS, is genuinely capable — but it's not the story. The 200MP Samsung ISOCELL HPB periscope telephoto is. It offers a real 85mm focal length with Zeiss APO (apochromatic) optics, meaning less colour fringing at the edges of the frame than a typical periscope lens, at 3.7x optical zoom backed by OIS, plus telephoto-macro focusing at a 2.7:1 ratio that lets you get genuinely close-up shots without switching to a dedicated macro lens. GSMArena's own camera testing found the lens produces detailed shots with great contrast and vibrant colours, continuing a reputation vivo's recent 85mm telephotos have built in GSMArena's own testing — this isn't a first-generation strength, it's a deliberate, repeated one. In good light, 3.7x through 10x shots hold detail remarkably well; even past that, the sheer sensor resolution keeps digital zoom shots usable in a way most phones can't match. The 50MP ultrawide, at f/2.0 with a 119° field of view and autofocus, is solid if unremarkable next to the telephoto's ambition, and the 50MP selfie camera with autofocus and a 92° field of view is a genuine nice touch for group shots. The honest caveat worth flagging directly: GSMArena's own pros-and-cons summary states low-light video quality plainly isn't quite up to scratch, a real, disclosed soft spot next to how strong the still-photo performance is across the rest of the system. For buyers who want to push the telephoto further still, vivo sells an optional Telephoto Extender Kit — a genuine, functional accessory, though one that carries a real, disclosed price premium specifically in EU markets. It's also worth knowing how this telephoto compares within vivo's own lineup: the standard X300 makes do with a shorter 50MP, 70mm, 3x optical Zeiss telephoto, so the Pro's extra reach and macro focusing is a genuine, meaningful step up rather than a marginal spec-sheet bump — the kind of difference worth paying for specifically if telephoto range is the deciding factor between the two models.

How It Compares to the Oppo Find X9 Pro

The Oppo Find X9 Pro is the closest genuine rival at a similar price, and GSMArena's own comparative verdict is specific about where each phone wins: the vivo takes the edge on camera overall, while the Oppo wins comfortably on battery endurance and costs less. That battery gap is real and substantial — the Find X9 Pro's 7,500mAh cell delivered an Active Use Score of 21 hours 57 minutes in GSMArena's lab testing, the highest result GSMArena had measured at the time, and crucially it reaches the UK and EU unreduced, unlike the X300 Pro's regionally-capped cell. Pricing reinforces that trade-off too: the Find X9 Pro starts at £899, a real £200 undercut against the X300 Pro's £1,099, which widens the practical case for it specifically if all-day battery confidence without compromise matters more to you than the specific character of vivo's Zeiss telephoto. Where the X300 Pro pulls ahead is optical reach and macro capability — its 3.7x, 85mm Zeiss APO lens with genuine telephoto-macro focusing goes further than the Find X9 Pro's own capable but shorter 3x, 70mm Hasselblad telephoto. Both phones share the same MediaTek Dimensity 9500 chipset and the same disclosed weakness of throttling under sustained gaming load, so the choice between them comes down less to raw performance and more to which specific trade-off — telephoto reach, or battery capacity and price — you're less willing to accept.

Who It's For

The X300 Pro is for a buyer who wants smartphone camera excellence above almost everything else, and who's willing to accept a real, EU-specific battery penalty to get it. GSMArena's own verdict names it a winner and a top choice for camera-focused buyers, even after weighing every trade-off. It's a strong fit for anyone specifically comparing it against the Find X9 Pro above — GSMArena gives the vivo the edge on camera overall, even though the Oppo wins comfortably on battery endurance and costs less. It's a weaker fit for anyone in the EU who prioritises all-day battery life without compromise, since the version sold there is capped well below the phone's real global capacity by an EU transport regulation on single-cell batteries — a real, disclosed reduction rather than a hypothetical concern, and the single most debated trade-off in this phone's entire review coverage.

Performance

MediaTek's Dimensity 9500 is a genuine flagship chip, not a mid-tier part wearing a flagship badge — GSMArena's own testing found top-class results with standout GPU numbers specifically, backed by the new all-big-core architecture pushing AnTuTu scores past 4 million. Everyday responsiveness is essentially instant, and the chip comfortably handles typical multitasking and gaming sessions without complaint. The honest caveat worth stating directly, though: GSMArena's testing found both the CPU and GPU can be affected by heavy throttling under sustained load — a real, measured limitation despite the chip's strong benchmark numbers, and worth knowing about specifically if you plan extended high-intensity gaming sessions rather than typical day-to-day use, where the issue doesn't show up. RAM runs 12GB or 16GB of LPDDR5X, paired with 256GB to 1TB of UFS 4.1 storage depending on configuration. OriginOS 6 on top of Android 16 is polished, if occasionally over-eager with its own app suggestions and notifications; a few minutes in settings pares that back easily enough.

Battery and Charging

Here's the detail that matters most before you buy: vivo caps EU units at 5,440mAh, while the rest of the world — including the UK, where this phone is officially sold — gets the full 6,510mAh cell. GSMArena's own review says it's most annoyed by this reduction specifically, and it's tied to a European transport regulation capping single-cell battery capacity rather than a deliberate product decision on vivo's part. For UK buyers, that full 6,510mAh silicon-carbon cell delivers comfortably through a full day of heavy use, with genuine two-day stamina for lighter users; anyone buying in continental Europe should expect noticeably less headroom from the smaller 5,440mAh version, and should weigh that specifically against the Find X9 Pro's unreduced 7,500mAh cell covered above if battery life matters more than telephoto reach. Charging is a genuine strength regardless of region — GSMArena's pros list specifically credits both proprietary and standard-charger compatibility at speeds that beat most rivals, backed by 90W wired charging that fills the phone from empty in under 40 minutes. 40W wireless charging, plus reverse wireless for topping up accessories like earbuds or a watch, rounds out a genuinely rare combination at this price point. The regional capacity cut isn't unique to the Pro, either — the standard X300 ships with 5,360mAh in the EU against 6,040mAh elsewhere, so this is a lineup-wide policy rather than a one-off decision specific to the flagship model, worth knowing if you're weighing both phones and assumed only the pricier one carried the trade-off.
