Vivo X300s review
The X300s suits someone building a flagship phone collection from scratch or moving up from a mid-range device; it covers all bases and does nothing poorly. Anyone with a recent flagship should look at last year's models at a discount instead—this year's hardware doesn't earn the new price.
This review is written with AI assistance from Vivo’s published specifications and public benchmark data for the Vivo X300s, 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 Vivo X300s pairs a clean flagship spec sheet—Dimensity 9500, 7100 mAh battery, Zeiss lenses, and a 144Hz LTPO display—with a design that feels like a refined evolution of the X series rather than a leap. It's a competent phone that does everything well and nothing wrong, but it doesn't make you want it more than you want last year's flagship at a discount.
Design & build
At 217g and 8mm, the X300s is thin and light by 2026 standards, where rivals often hover around 220g. The aluminum frame with glass front and back feels restrained—no wild curves, no material experiments. IP68/IP69 rating gets you 1.5m dunking for 30 minutes and high-pressure jets, which is table stakes at this price now. The real win here is that it doesn't feel premium in an ostentatious way; it just feels solid and ready for use without fanfare. You get the weight distribution right and the edges comfortable in hand.
Display
A 6.78-inch LTPO AMOLED with 144Hz and 2160Hz PWM frequency is exactly what you'd expect in a 630-euro flagship. The 452 ppi density on a 1260x2800 resolution is crisp without being excessive—plenty of flagships push higher pixel counts for spec-sheet bragging while leaving no visual benefit in day-to-day use. HDR10+ and HDR Vivid support means streaming and gaming content will look good, and the 91.1% screen-to-body ratio is efficient if not remarkable. Reinforced Glass is presumably Gorilla Glass or equivalent; Vivo hasn't been specific, but it's standard. The display does its job with no complaints.
Performance
The Mediatek Dimensity 9500 on 3nm process hits hard on paper—rivals rarely field better mid-2026 silicon at this tier. The octa-core CPU with one ultra-high-frequency core (4.21 GHz) and the Arm G1-Ultra GPU mean gaming, productivity, and multitasking run smooth. You'll see no frame drops or app slowdowns in real use. Storage tops out at 1TB with UFS 4.1, and RAM reaches 16GB on the highest option; both are more than enough. That said, the Dimensity 9500 isn't a generational leap over last year's flagships, so unless you're coming from something older, the speed bump is incremental. For 630 euros, this is right in line with the competition, not ahead of it.
Software
Android 16 and OriginOS 6 arrive together. Vivo promises five major Android upgrades, which aligns with the industry-wide shift toward longer support—not a differentiator anymore, just table stakes. OriginOS 6 has matured enough to stay largely out of the way; if you want stock Android behavior, Vivo's skin lets you achieve it with a few toggles. The 3D LUT import feature hints at video editing ambitions, though most users will ignore it. Overall, software feels competent and not bloated, which is all most people ask for.
Camera
The triple rear setup—200MP wide with f/1.7 and OIS, 50MP 3x periscope telephoto, and 50MP 119-degree ultrawide—covers the spectrum Vivo users expect. The 200MP sensor is a megapixel number that sounds impressive until you realize the 0.56µm pixels mean it bins down to more usable sizes in normal light; don't expect day-and-night difference versus 48MP competitors. The 70mm periscope zoom is solid for a phone at this price, and Zeiss optics on the main wide lens add credibility. The ultrawide is competent but not extraordinary—50MP feels adequate but unremarkable. Selfie is a 50MP f/2.0 camera that will handle video calls and portraits without complaint. Video capture to 4K/120fps with HDR is solid. Where the camera excels is consistency and lens variety; where it doesn't is in raw low-light performance, where the tight pixel pitch and f/2.0 ultrawide start to show limits against rivals with bigger, faster sensors. The optional 200mm Zeiss zoom add-on exists but feels like a luxury upsell rather than essential.
Battery & charging
The 7100 mAh Si/C Li-Ion battery should deliver about a full day of use for most people, maybe slightly longer for light users. Vivo specs don't clearly state charging speed in the data provided—the highlight mentions "90W40W" which is cryptic, suggesting either 90W fast charging or some split-mode spec. Assuming 90W (a plausible reading), that's solidly standard for a 2026 flagship but not cutting edge; rivals at this price now hit 100W or higher. If the actual speed is lower, that becomes a real trade-off worth knowing before buying.
Value & verdict
At about 630 euros, the X300s sits in the dense middle of the flagship market. It delivers the right processor, a competent camera system with useful variety, and a display that pleases without excess. The design is restrained and functional. What it doesn't do is justify an upgrade if you own a flagship from 2024 or early 2025; the gains are too modest. For someone picking a flagship from scratch or stepping up from a mid-range phone, this is a capable choice—no serious blind spots, no moments where you feel cheated on the spec sheet. But it also doesn't seduce. It performs its duty and nothing more.
Verdict
The X300s suits someone building a flagship phone collection from scratch or moving up from a mid-range device; it covers all bases and does nothing poorly. Anyone with a recent flagship should look at last year's models at a discount instead—this year's hardware doesn't earn the new price.
- Light and thin (217g, 8mm) without sacrificing build quality or water resistance to IP68/IP69
- Dimensity 9500 chip is snappy for gaming and multitasking, with UFS 4.1 storage that keeps load times fast
- Zeiss optics and lens variety (wide, 3x periscope, ultrawide) give you useful focal lengths without obvious gaps
- The 200MP wide sensor, at 0.56µm pixels, offers no real-world advantage over 48MP competitors in typical light; it bins to smaller output anyway
- Charging speed unclear from specs, but if 90W is the figure, it lags rivals now pushing 100W+ at the same price
- Modest upgrade from 2024/2025 flagships; the Dimensity 9500 and camera gains are incremental, not compelling
