Display Comparison
The OnePlus Nord 5 boasts a significantly brighter display, reaching a measured peak of 1330 nits, compared to an unspecified brightness for the vivo Y51s. This higher brightness translates to superior visibility in direct sunlight. While the Y51s’ panel technology isn’t specified, the Nord 5’s brightness advantage suggests a more advanced panel, potentially with higher contrast. Bezels are likely comparable given the market segment, but the Nord 5’s superior brightness is a clear win for outdoor usability.
Camera Comparison
Without detailed camera specifications for either device, a direct comparison is limited. However, given the Nord 5’s positioning, it’s reasonable to expect a more sophisticated camera system with a larger main sensor and potentially optical image stabilization (OIS). The Y51s likely relies on software processing to compensate for a potentially smaller sensor. The inclusion of a 2MP macro camera on the Y51s is a common, but often underwhelming, feature, offering limited practical benefit compared to a well-tuned primary sensor.
Performance
The core difference lies in the chipsets. The OnePlus Nord 5’s Snapdragon 8s Gen 3 (4nm) is a substantial upgrade over the vivo Y51s’ Exynos 880 (8nm). The Snapdragon 8s Gen 3 features a Cortex-X4 prime core clocked at 3.0 GHz, alongside Cortex-A720 performance cores, offering a significant leap in CPU performance. The Exynos 880’s Cortex-A77 cores, while capable, are older and less efficient. The 4nm process node of the Snapdragon 8s Gen 3 also provides better thermal efficiency, reducing the likelihood of throttling during sustained workloads like gaming. The Nord 5 is the clear winner for demanding users.
Battery Life
The OnePlus Nord 5 excels in battery performance and charging. Its 49:12h endurance and 13:47h active use score demonstrate impressive longevity. Crucially, the 80W wired charging, with support for 33W PPS and 18W PD, can fully charge the device in just 54 minutes. The vivo Y51s, with only 18W wired charging, will take considerably longer to reach 100%. While the Y51s’ battery capacity isn’t specified, the Nord 5’s faster charging and overall endurance make it the more convenient option for users who prioritize minimizing downtime.
Buying Guide
Buy the vivo Y51s if you prioritize extreme affordability and basic smartphone functionality, and are willing to compromise on performance and charging speed. You'll appreciate its lower price point for everyday tasks. Buy the OnePlus Nord 5 if you demand a smoother, more responsive experience, especially for gaming and demanding applications, and value rapid charging and a vibrant display. It’s the better investment for power users.
