Design & Display: Compact, but Clearly Premium
The moment you pick up the Vivo X300, the size stands out—in a good way. The 6.31-inch flat AMOLED display makes one-handed use comfortable again, without sacrificing flagship-level visuals.
vivo’s move from LTPS to next-gen 8T LTPO technology is a serious upgrade. The screen intelligently scales from 1 Hz to 120 Hz, saving battery during reading or scrolling static content, while still feeling buttery smooth during animations and gaming.
Brightness is another strong point. With 2000 nits of high brightness and a 4500-nit peak, outdoor visibility is never an issue. Add 2160 Hz PWM dimming and Zeiss color management, and the Vivo X300 becomes one of the most eye-friendly compact phones around.
The ultra-narrow 1.05 mm symmetrical bezels deserve special mention—they give the phone a clean, modern look that easily competes with larger flagships.
Software Experience: Origin OS 6 Feels Mature
The Vivo X300 runs Origin OS 6 based on Android 16, and the difference from older FunTouch OS is instantly noticeable. The interface feels smoother, more intentional, and less cluttered.
Features like Origin Island bring live activities—music, timers, deliveries—into a dynamic space at the top of the display, while Atomic Notifications keep alerts organized instead of overwhelming.
Vivo’s promise of 5 years of Android updates and 7 years of security patches adds serious long-term value, especially for users who keep their phones for years.
Performance & Gaming: Compact, but Extremely Powerful
Under the hood, the Dimensity 9500 (3 nm) with its all-big-core architecture delivers raw performance without hesitation. Hitting nearly 3 million on AnTuTu, the Vivo X300 handles heavy multitasking effortlessly.
Gaming performance is equally impressive. Titles like BGMI and Call of Duty run at 120 FPS, staying stable thanks to the vapor chamber cooling system.
There is, however, one limitation worth noting. While gaming temperatures stay controlled, continuous 4K video recording can push the device to around 50°C, especially under direct sunlight. It’s not a deal-breaker, but it’s something video creators should keep in mind.
Camera System: Versatile, Powerful, Slightly Opinionated
The headline upgrade is the 200MP primary sensor with OIS, capable of shooting 4K at 120fps. Photos are detailed and sharp, though Vivo’s tuning leans slightly toward boosted colors.
The 50MP telephoto lens isn’t just for zoom. With 3x optical, up to 100x digital zoom, and tele-macro support, it allows detailed close-ups without disturbing the subject—a genuinely useful feature.
The V3+ imaging chip, previously limited to Pro models, handles cinematic portrait video and complex processing. Multi-focal portrait modes (23 mm to 100 mm) add creative flexibility that photography enthusiasts will appreciate.
The 50MP selfie camera delivers crisp results with 4K 60fps video, though low-light selfies can struggle a bit compared to daylight shots.
Battery & Charging: Big Capacity, Practical Results
Packing a 6040 mAh battery into a compact phone is no small achievement. Under heavy usage, the Vivo X300 delivers around 8 hours of screen-on time, which easily translates to 1.5 days for normal users.
Charging is fast and flexible. 90W wired charging fills the battery in about an hour, while 40W wireless charging adds convenience without compromise.
Extras That Actually Matter
The upgrade to an ultrasonic fingerprint scanner is subtle but impactful. It works even with wet or oily fingers and unlocks in just 0.2 seconds—once you use it, optical scanners feel outdated.
Other premium touches include
-
USB 3.2 for lightning-fast file transfers
-
Wi-Fi 7 & Bluetooth 5.4 for future-ready connectivity
-
X-axis linear motor delivering crisp, satisfying haptics
-
Glass back, aluminum frame, and IP68/IP69 durability
At 194 g, the phone feels solid without being bulky.
Vivo X300 verdict
The vivo X300 isn’t about flashy gimmicks; it’s all about providing a polished flagship experience in a compact size that many users have been craving.
Sure, it comes with a price tag of around ₹75,999, and there are some thermal limitations to consider during long 4K recording sessions. However, the impressive LTPO display, hefty battery, ultrasonic security features, and commitment to long-term software updates make the Vivo X300 one of the most well-rounded compact flagships as we head into 2026.
If you’re looking for power without the bulk—and prefer refinement over noise—the Vivo X300 is definitely one of the smartest choices you can make.
