Build and Feel

The Vivo X300 E adopts a premium glass-and-aluminum construction with IP68/IP69 protection, delivering a refined flagship feel while maintaining a clean, minimalist design. Zeiss branding also adds a premium touch for photography enthusiasts. The phone feels modern without focusing on flashy styling, making it suitable for users who prefer understated aesthetics.

The OnePlus 15 also features an aluminum frame with Gorilla Glass Victus 2 protection and IP68/IP69K certification. Its stronger display protection, optional Crystal Shield finish, and eSIM support make it slightly more versatile. The overall design feels more rugged and premium, especially for users looking for extra durability alongside flagship styling.

Display Quality

Vivo equips the X300 E with a 6.59-inch AMOLED panel featuring a 144Hz refresh rate, HDR support, and an impressive 5,000-nit peak brightness. The display delivers excellent outdoor visibility, vibrant colors, and sharp detail while remaining compact enough for comfortable one-handed use.

The OnePlus 15 counters with a larger 6.78-inch LTPO AMOLED display offering a faster 165Hz refresh rate, Dolby Vision, HDR10+, Ultra HDR support, and adaptive refresh technology. Although its peak brightness rating is lower on paper, the richer HDR ecosystem and LTPO technology make the experience more polished for multimedia consumption.

Verdict

The Vivo X300 E excels with exceptional brightness and a more compact display, while the OnePlus 15 delivers the more complete flagship screen thanks to LTPO technology, Dolby Vision, stronger protection, and a higher refresh rate. Display enthusiasts will likely prefer the OnePlus 15.

Performance

Both smartphones are built around Qualcomm’s latest 3nm flagship processors and offer UFS 4.1 storage for extremely fast app launches and file transfers. The Vivo X300 E uses the Snapdragon 8 Gen 5, delivering flagship-grade speed suitable for demanding games, AI workloads, and heavy multitasking without compromise.

The OnePlus 15 raises performance further with the Snapdragon 8 Elite Gen 5, featuring higher CPU frequencies and additional RAM configurations reaching 16GB and 1TB storage. Combined with OxygenOS 16, it offers greater long-term flexibility for power users. The extra performance headroom makes it feel slightly more future-ready.

Battery and Charging

Battery life is outstanding on both devices. Vivo packs a massive 7,200mAh battery with 90W wired charging, comfortably lasting beyond a full day of intensive use. Its focus leans toward endurance rather than charging versatility.

The OnePlus 15 includes an even larger 7,300mAh battery with 120W wired charging, 50W wireless charging, reverse wireless charging, bypass charging, and support for multiple charging standards. It offers one of the most complete charging packages currently available in a flagship smartphone.

Verdict

Performance differences are relatively small for everyday use, but the OnePlus 15 delivers stronger processing power, more storage options, faster wired charging, wireless charging, and broader charging features. Users seeking the most complete hardware package will find the OnePlus 15 more compelling.

Main and Secondary Lenses

The Vivo X300 E features a Zeiss-backed triple camera system consisting of a 50MP primary camera, a 50MP 3x periscope telephoto lens, and an 8MP ultrawide sensor. Zeiss optics and image tuning should deliver attractive colors and portraits, while the large telephoto sensor enhances zoom quality. The setup emphasizes photography consistency rather than headline specifications.

The OnePlus 15 offers three 50MP cameras, including a main sensor, a 3.5x periscope telephoto lens, and a high-resolution ultrawide camera. Video capabilities extend to 8K recording, Dolby Vision, LUT support, and advanced autofocus features. The more balanced hardware makes it better suited for both photography and professional-grade videography.

Selfie Camera

Vivo impresses with a high-resolution 50MP autofocus selfie camera capable of 4K recording, offering excellent flexibility for selfies and video calls. The autofocus system should help maintain sharpness in varying shooting conditions.

OnePlus includes a 32MP autofocus front camera with 4K 60fps recording and HDR support. While its resolution is lower, the smoother frame rate benefits creators recording higher-quality front-facing videos.

Verdict

The Vivo X300 E has the stronger selfie hardware and capable Zeiss imaging, but the OnePlus 15 offers the more versatile flagship camera experience with triple 50MP sensors, superior ultrawide performance, richer video features, and better overall shooting flexibility.

The Vivo X300 E is priced around $700 (approximately ₹68,200), positioning it as an affordable premium flagship. Considering its Snapdragon 8 Gen 5 chipset, Zeiss cameras, 144Hz AMOLED display, and enormous 7,200mAh battery, the pricing feels highly competitive. It delivers flagship essentials without pushing into ultra-premium territory, making it particularly attractive for buyers prioritizing value.

The OnePlus 15 is priced around $800 (approximately ₹73,000), placing it roughly $100 higher. The premium brings meaningful upgrades, including the Snapdragon 8 Elite Gen 5, LTPO AMOLED display, faster 120W charging, wireless charging, 8K video recording, and more advanced connectivity. The additional cost feels justified for users seeking the most complete flagship experience rather than simply strong specifications.

Verdict

The Vivo X300 E delivers better overall value for money and offers flagship hardware at a lower price. The OnePlus 15 justifies its premium through meaningful upgrades, making it worthwhile for buyers wanting every modern flagship feature.
