Vivo X300 series is shaping up as a battery-first flagship with big cells, fast charge, Dimensity power and camera upgrades. Here are five confirmed takeaways.
Introduction
Vivo X300 series is getting wide attention before its Oct 13 reveal. Leaks and early hands-ons point to a clear strategy: much bigger batteries plus solid flagship hardware. Here are five real things we can say now.
Vivo X300 — 5 confirmed takeaways (Vivo X300 key facts)

- Big batteries: The X300 Pro is reported to pack about 6,510 mAh, while the standard X300 is much larger than last year too (around 6,040 mAh in leaks). That is a clear battery jump for both models.
- Fast wired charging: Reports show the series supports around 90W wired charging, so you get quick top-ups as well as a big cell. That combo is aimed at real all-day use.
- Flagship chipset (regional variants): The X300 line pairs flagship-class silicon (Dimensity 9500 in many regional leaks) to balance power with efficiency. Expect high performance for apps and games.
- Camera & tuning focus: Hands-on posts show Vivo is pushing camera tuning (new optics and software). Early sample photos from prelaunch units hint at better low-light and color handling. Full review tests will confirm how big the real gain is.
- Real-world intent, not just specs: Leaks and hands-on videos stress battery life and day-long use as the headline benefit — not just headline CPU numbers. That matters if you want phones that actually last a full day under heavy use. Beebom Gadgets
Conclusion
Vivo is betting the X300 family on long battery life plus respectable flagship power. The Oct 13 launch should confirm exact specs and camera samples — then lab tests will show the real endurance and photo wins. Notebookcheck
