Vivo X300 review: specs, battery & used prices

Summary

The Vivo X300 is the 2025 compact flagship that punches above its size on every axis: a 200 MP main camera with Zeiss tuning, the MediaTek Dimensity 9500, a 6,040 mAh battery in a 6.31-inch 190 g body, and IP69 protection. It sells new for about $799, and 12/512 GB units already trade used for around $696 — our camera score of 89/100 is among the highest we award at any price.

Display and design

The 6.31-inch OLED runs at 120 Hz with a 2,000-nit peak, scoring 77/100 on screen quality. The packaging is the achievement: a compactness score of 86/100 with a battery this size has no real precedent in the catalog, and IP69 adds jet-water protection to submersion resistance.

Performance

The Dimensity 9500 is 2025's efficiency leader, and our gaming score of 89/100 places the X300 at the very front of sustained 3D performance — remarkable for a compact body, and evidence of how far thermal design has come. Five years of updates from 2025 leaves roughly four remaining, a solid runway.

Camera

The 200 MP stabilised main sensor anchors a Zeiss-tuned triple system with ultrawide and telephoto companions, capturing video up to 4K at 120 fps. The camera score of 89/100 ranks alongside phones costing twice as much, with the main sensor's crop room doing much of the zoom work.

Battery and charging

The 6,040 mAh battery earns a 61/100 battery-life score — compact-phone endurance that embarrasses larger flagships — with 90 W wired charging at 71/100 for sub-hour full charges.

Verdict

The Vivo X300 is the best camera-per-gram phone we track and a top-tier performer at around $696 used or $799 new. Its friction points are practical: import-channel availability and Zeiss-tuned processing that favours punchy colour over neutrality. If you want the same camera philosophy with maximum zoom hardware, the Vivo X200 Ultra goes further in a bigger body; for a wider software runway, the Pixel line remains the alternative.
