1. Design and Display

Build and Feel
OPPO Reno 15 leans into a sleek, modern aesthetic with a balanced, premium feel that suits long daily use. Its glass-and-metal construction feels polished rather than flashy, and the design prioritizes comfort over compactness. Vivo X300, on the other hand, targets users who prefer a tighter, denser form factor with a more “flagship-grade” in-hand confidence. The build feels slightly more refined, helped by details like an ultrasonic fingerprint sensor that subtly elevates daily interactions. Reno 15 feels practical and familiar, while X300 feels engineered and deliberate, appealing to users who value precision.

Display Quality
Reno 15’s AMOLED panel delivers rich colors, smooth scrolling, and reliable brightness for everyday use. It’s tuned for consistency rather than extremes. Vivo X300 clearly pushes display technology further with LTPO tech, advanced HDR formats, and extremely high peak brightness. Content looks more dynamic and adaptive, especially for streaming and gaming. The difference is noticeable in side-by-side use, where Vivo’s panel simply feels more “alive.”

Verdict
Reno 15 offers a comfortable, high-quality experience, but Vivo X300’s display and finish feel unmistakably more flagship-level.

2. Specifications 

Performance
OPPO Reno 15 is powered by a Snapdragon 7-series chip that focuses on efficiency and stability. Day-to-day performance is smooth, with reliable multitasking and controlled thermals, making it well-suited for extended use without surprises. Vivo X300 takes a more aggressive approach with a cutting-edge 3nm chipset and faster storage. App launches, gaming, and heavy workloads feel noticeably quicker, and the headroom for future software updates is reassuring. The X300 simply feels more effortless when pushed hard.

Battery and Charging
Reno 15 prioritizes endurance, offering excellent battery longevity paired with fast wired charging that minimizes downtime. It’s designed for users who value consistency over extras. Vivo X300 counters with slightly smaller capacity but faster wired charging and the added convenience of wireless charging. This flexibility makes it feel more adaptable to different lifestyles, especially for desk or car charging setups.

Verdict
Reno 15 wins on predictable all-day reliability, while Vivo X300 delivers superior raw power and charging versatility.

3. Camera

Main and Secondary Lenses
OPPO Reno 15 offers a well-rounded camera system with reliable color reproduction, effective stabilization, and a useful telephoto lens that adds genuine versatility. Images are consistent and social-media ready with minimal effort. Vivo X300 clearly targets photography enthusiasts, led by a high-resolution main sensor and Zeiss-tuned optics. Photos show more detail, better dynamic range, and a slightly more cinematic character. Advanced video modes and higher frame-rate options reinforce its flagship intent. Reno 15 feels dependable; X300 feels expressive.

Selfie Camera
Both phones deliver strong selfie performance with autofocus support, but Vivo’s processing tends to preserve more natural skin tones and finer detail in varied lighting. OPPO’s selfies are sharp and vibrant, favoring a cleaner, polished look that many users will enjoy.

Verdict
Reno 15 is consistently good across scenarios, but Vivo X300 offers a more advanced and creatively flexible camera experience.

4. Pricing

OPPO Reno 15 enters the market at approximately $500, positioning itself as a strong upper-midrange option with flagship-inspired features. At this price, it delivers excellent battery life, solid performance, and a versatile camera setup that meets most users’ needs without excess. Vivo X300 is priced around $650, clearly stepping into compact flagship territory. The higher cost brings tangible upgrades in chipset performance, display technology, camera hardware, and long-term software support.

Reno 15 makes more sense for value-focused buyers who want premium features without stretching budgets. Vivo X300 justifies its higher price by offering a more future-proof, top-tier experience, especially for users who prioritize performance, display quality, and camera innovation.
