A 200MP Zeiss APO periscope telephoto with a genuine 85mm focal length and telephoto-macro focusing, paired with a gimbal-grade OIS main camera — the most complete camera flagship vivo has shipped globally, even without the Ultra's teleconverter party trick.

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 Oppo Find X9 Pro — 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 prioritizes 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.
The telephoto camera is the clearest, most repeatedly praised strength — GSMArena's camera testing found the 85mm Zeiss lens produces detailed shots with great contrast and vibrant colors, continuing a reputation vivo's recent 85mm telephotos have built in GSMArena's own testing. Display brightness comfortably beat vivo's own marketing claims in independent testing: GSMArena measured 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. Charging is a real, class-leading strength too — GSMArena's pros list credits both proprietary and standard-charger compatibility at speeds that beat most rivals. Performance is a second standout: GSMArena's testing found top-class results with standout GPU numbers specifically, backed by the new all-big-core Dimensity 9500 pushing toward AnTuTu scores past 4 million.
Battery capacity is the single most disclosed, most debated trade-off in this catalog — vivo caps EU units at 5,440mAh against 6,510mAh for the rest of the world, a real reduction GSMArena's own review says it's most annoyed by, tied to a European transport regulation capping single-cell battery capacity rather than a deliberate product decision. Heavy throttling is a second, genuinely measured weakness: GSMArena's testing found both the CPU and GPU can be affected under sustained load, a real limitation despite the chip's strong benchmark numbers. Low-light video quality is a specific, disclosed soft spot too — GSMArena's own pros-and-cons summary states it plainly as not quite up to scratch. Speaker quality also has real room for improvement per GSMArena's testing, and the optional Telephoto Extender Kit — while a genuine, functional accessory — carries a real, disclosed price premium in EU markets specifically.
