Samsung Galaxy A51 5G

  • Excellent battery endurance (90h)
  • Lower price point (likely)
  • Established Samsung ecosystem

  • Outdated Exynos 980 chipset
  • Slow 15W charging
  • Dimmer display compared to Nord 5

OnePlus Nord 5

  • Powerful Snapdragon 8s Gen 3 chipset
  • Blazing-fast 80W charging (54 min)
  • Bright and vibrant display (1330 nits)
  • Reverse wired charging

  • Slightly lower endurance rating than A51 5G
  • Potentially higher price

Display Comparison

The OnePlus Nord 5’s display is a clear winner, boasting a peak brightness of 1330 nits compared to the Galaxy A51 5G’s 642 nits. This translates to significantly better visibility outdoors, especially in direct sunlight. While both displays have an 'infinite' (nominal) contrast ratio, the higher brightness of the Nord 5 provides a more vibrant and engaging viewing experience. The A51 5G’s display, while adequate, feels dated in comparison, lacking the punch and clarity of the Nord 5’s panel.

Camera Comparison

Both devices offer photo and video capabilities, but detailed sensor information is limited for the A51 5G. The Nord 5 benefits from a newer image signal processor (ISP) within the Snapdragon 8s Gen 3, likely resulting in improved image processing and noise reduction. Without specific sensor size data for the A51 5G, it’s difficult to make a definitive judgment, but the Nord 5’s modern chipset provides a strong foundation for superior image quality. The A51 5G’s camera is likely adequate for casual photography, but the Nord 5 is expected to deliver more consistent and detailed results.

Performance

The performance gap between these two devices is substantial. The OnePlus Nord 5’s Qualcomm SM8635 Snapdragon 8s Gen 3 (4nm) is built on a more efficient node than the Galaxy A51 5G’s Exynos 980 (8nm), resulting in better thermal management and sustained performance. The Nord 5’s CPU configuration – a Cortex-X4 prime core alongside A720 and A520 cores – offers a significant architectural advantage over the A51 5G’s Cortex-A77 and A55 cores. This translates to faster app loading times, smoother multitasking, and a more responsive overall user experience. The Nord 5 is better equipped for demanding tasks like gaming and video editing.

Battery Life

The Galaxy A51 5G boasts an endurance rating of 90 hours, a respectable figure. However, the OnePlus Nord 5 counters with a 49:12h endurance rating and a remarkable 13:47h active use score. Crucially, the Nord 5’s 80W wired charging dramatically reduces downtime, achieving a full charge in just 54 minutes. The A51 5G’s 15W charging is comparatively slow. While the A51 5G may last longer on a single charge, the Nord 5’s rapid charging capabilities minimize the impact of battery drain, making it more convenient for users who frequently top up their devices.

Buying Guide

Buy the Samsung Galaxy A51 5G if you prioritize long-term battery endurance and are on a very tight budget, accepting a noticeable performance deficit. Buy the OnePlus Nord 5 if you value speed, responsiveness, and significantly faster charging, and are willing to spend a bit more for a more modern and capable device. The Nord 5 is ideal for gamers and power users.

Frequently Asked Questions

❓ Does the Exynos 980 in the Galaxy A51 5G overheat during prolonged gaming sessions?
The Exynos 980 is known to throttle under sustained load, meaning performance will decrease over time during extended gaming. The 8nm process isn't as efficient as the 4nm process in the Snapdragon 8s Gen 3, leading to higher temperatures and reduced clock speeds.
❓ How does the 80W charging on the OnePlus Nord 5 affect battery health over the long term?
While fast charging can theoretically accelerate battery degradation, OnePlus implements charging management algorithms to mitigate this effect. The Nord 5 also supports PPS and PD charging standards, allowing for optimized charging profiles. The 1200 cycle rating suggests a robust battery designed to withstand frequent fast charging.
❓ Is the reverse wired charging feature on the OnePlus Nord 5 useful for everyday scenarios?
The 5W reverse wired charging is primarily useful for topping up accessories like wireless earbuds or smartwatches in a pinch. It's not designed to quickly charge other phones, but provides a convenient solution for smaller devices.
❓ What kind of gaming performance can I expect from the Snapdragon 8s Gen 3 in the OnePlus Nord 5?
The Snapdragon 8s Gen 3 is capable of running most modern mobile games at high settings with smooth frame rates. While not a flagship-tier chip, it offers a significant performance boost over the Exynos 980, allowing for a more enjoyable gaming experience.
