Vivo X300 Review: The Most Complete Compact Flagship of Its Generation

The Vivo X300 is the compact entry point into Vivo's current flagship trio, sitting below the X300 Pro and the internationally-launched X300 Ultra reviewed elsewhere on this site. Beebom Gadgets called it "the most complete baseline flagship yet" — a genuinely strong claim that independent reviews have largely backed up.

Design and Build

Available in Elite Black, Summit Red, and Cloud White, at just 150.6 x 71.9 x 8.0mm and 190g with IP68/IP69 water and dust resistance, the X300 is genuinely compact by 2026 flagship standards. Business Standard's review specifically praised how comfortable it is for extended one-handed use — scrolling, typing, and general handling all benefit from the smaller footprint compared to the Pro. The back panel uses what Vivo calls a Coral Velvet Glass technique — GSMArena's hands-on testing found it genuinely smudge-repellent with a soft, almost velvety matte texture, though also noticeably slippery as a real trade-off of that finish. The camera island is visually related to the pricier X300 Pro's but sits noticeably less proud of the back panel, part of how Vivo kept the compact model feeling genuinely lightweight rather than just smaller on paper. GSMArena's testing found the under-display fingerprint reader (an ultrasonic unit, faster and more reliable than the optical sensors many rivals still use) works quickly and consistently. One specific, repeated weakness worth knowing about, though: speaker quality is a real, disclosed shortfall across the whole X300 lineup, not just this model — GSMArena's own cons list calls it merely "so-so," a genuine comparative gap against rivals that prioritize audio more.

Display

A 6.31-inch AMOLED panel at 1216 x 2640 resolution runs up to 120Hz behind reinforced glass. GSMArena's review specifically praised the "super bright screen" with impressively dynamic refresh rate handling — a strong, if not class-leading, display for the compact form factor. The brightness figures back that up with real, measured results, if a real gap versus the marketing claim: GSMArena's own lab testing found roughly 2,000 nits in auto mode on a 75% patch and just over 2,650 nits at a smaller 10% window, genuinely bright in absolute terms but meaningfully short of the marketed 4,500-nit peak figure — a real, disclosed gap between spec sheet and lab result worth knowing, even if the real-world result is still a strong one.

Camera

A 200MP Samsung HPB main sensor at 1/1.4-inch, paired with a genuine 50MP Sony LYT-602 telephoto offering 3x optical zoom with Zeiss APO tuning and OIS, plus a 50MP autofocus ultrawide and a 50MP autofocus front camera, make up the system. Notebookcheck's review specifically called the 200MP Zeiss lens' output "genuinely strong," while 91Mobiles found the X300 the only phone in its comparison cluster to consistently deliver class-leading camera quality against rivals like the OnePlus 15 and Realme GT 8 Pro. GSMArena's own testing found photo quality reliably great in both day and night conditions, specifically praising the wide-angle camera as one of the best available on any phone that year, with portrait mode at 1x delivering what its review calls outstanding, believably natural background blur. Selfies got a genuine hardware upgrade this generation too — the front camera moved to the same capable 50MP autofocus sensor used on the rear ultrawide, a real step up GSMArena calls top-notch, and daylight video paired with outstanding stabilization — a genuinely consistent, well-rounded camera system rather than one that only excels in ideal conditions. Video tops out at 4K60 on the main camera, with 4K120 available for slow-motion capture, and GSMArena's testing credits the Dimensity 9500's newer image-processing hardware with a real, measured 11.9% improvement in low-light noise handling over the previous generation's chip — a genuine generational gain rather than just a marketing claim, even if low-light video is still the one honestly disclosed soft spot GSMArena flags directly, a real gap next to the phone's otherwise strong daylight footage. The X300 also supports Vivo's optional 2.35x teleconverter kit — a genuine versatility feature that 91Mobiles noted as unique among flagships in this price bracket, and one normally reserved for pricier models that Vivo extended to the standard X300 this generation.

Software

The X300 marks a genuinely significant software milestone for Vivo: it runs OriginOS 6 on Android 16, the first time the brand's more polished Chinese-market interface has replaced FuntouchOS — the noticeably more dated software international buyers were stuck with for years — on a global model. Vivo backs it with 5 major Android updates plus 2 extra years of security patches, 7 years total, a genuinely strong, class-competitive commitment. Vivo's own claims for the update's under-the-hood "Ultra-Core computing" system — up to 18.5% faster app cold starts and 10.5% more stable frame rates during scrolling — are manufacturer-sourced figures rather than independently re-measured, worth treating as a directional claim rather than a verified benchmark. OriginOS 6 also brings genuine visual polish beyond the raw performance claims: more responsive animations built around bounciness and blur-transition effects, and gesture-mirroring velocity that GSMArena's testing found made the whole interface feel noticeably more fluid than the FuntouchOS it replaces internationally. Connectivity is comprehensive for the price: Wi-Fi 7, Bluetooth 5.4 with aptX HD and LHDC 5 support, NFC, and an infrared port for using the phone as a remote — a feature a growing number of flagships have quietly dropped.

Performance

MediaTek's Dimensity 9500 on a 3nm process, with 12 or 16GB of RAM, delivers what GSMArena called "presumably the fastest Android hardware" available at launch. 91Mobiles did note one honest trade-off: rivals like the OnePlus 15 and Realme GT 8 Pro offer higher sustained performance under heavy gaming or multitasking loads, making them the better pick specifically if raw, sustained power is the top priority over camera and compactness. GSMArena's own cons list is more specific about why: it found the X300 prone to heavy throttling and getting hot under sustained load, a real, disclosed limitation despite the chipset's otherwise strong benchmark results and one worth weighing if extended gaming sessions matter to you specifically. Storage runs from 256GB up to a genuinely generous 1TB on the fastest UFS 4.1 standard, with 12GB or 16GB of LPDDR5X RAM depending on configuration — both comfortably in line with what rival flagships at this price offer, even in the compact model rather than being held back by the smaller body.

Battery and Charging

A 6,040mAh battery with 90W wired and 40W wireless charging delivers what Business Standard called "very solid endurance for a compact device" — comfortable all-day use with an easy stretch into a second day under moderate use, and GSMArena's own pros list credits battery life as a genuine highlight even before accounting for the fast charging speed. One real, disclosed regional trade-off is worth correcting here directly: unlike what this review previously suggested, the X300 does not avoid the regional battery downgrade that affects the X300 Pro. GSMArena's own review confirms EU units ship with a smaller 5,360mAh battery against the 6,040mAh capacity sold in the rest of the world, the same pattern seen across the wider X300 lineup — a genuine, disclosed downside specifically for European buyers, not a strength unique to the standard model over its pricier sibling.

How It Compares

GSMArena's own verdict calls the X300 an exemplary phone across nearly every category it measures — size, design, battery life, screen quality, and camera experience — and its direct head-to-head against the Google Pixel 10 Pro at a similar price finds the vivo the more powerful, more skilled camera phone overall, a genuinely strong claim against Google's own computational-photography flagship. The same review found it beats the Samsung Galaxy S25 specifically on camera quality and battery life, and beats the Xiaomi 15 on premium feel despite the vivo's higher price — real, named comparative wins rather than vague positioning against unnamed rivals. The performance gap against the standard Google Pixel 10 specifically is stark in raw benchmark terms: 91mobiles' own comparison tooling recorded a Geekbench multi-core score of 10,129 for the X300 against 6,325 for the Pixel 10, a real, measured gulf that reflects Google's well-documented preference for efficiency and camera processing over raw silicon throughput rather than any weakness specific to that generation of Pixel.

Price and Availability

The X300 launched officially in Europe at €1,049 and in India, but Vivo has maintained a standing "paused business in the UK" message on its UK site for years now — the same pattern that has kept the whole X300 family, including this model and the Ultra, out of official UK retail. That makes the £899 pricing referenced throughout this review an import price rather than an official UK RRP, consistent with how Vivo phones are typically bought in Britain. Notebookcheck's own import guide found genuinely worthwhile savings available through third-party retailers sourcing the global model directly, with the trade-offs worth knowing upfront: no official local warranty, and the usual caveats around buying outside your own market. For anyone specifically comparing against Chinese-market pricing, Notebookcheck also found the global import version carries no significant restriction on network bands and, unlike some Xiaomi imports, ships with English and other languages built in even on China-market units, easing one common import headache. The Chinese-market model does come with a real, disclosed catch worth weighing against the savings: Notebookcheck's import guide notes there are no official update promises attached to units sourced that way, unlike the 7-year commitment Vivo makes for officially-sold global models, so buyers trading a lower price for a China-market unit are also trading away that update guarantee specifically.
