Samsung Galaxy M31

  • Lower price point
  • Potentially larger display size (unconfirmed)
  • Acceptable performance for basic tasks

  • Outdated Exynos 9611 chipset
  • Slow 15W charging
  • Likely inferior display quality

OnePlus Nord 5

  • Powerful Snapdragon 8s Gen 3 chipset
  • Ultra-fast 80W charging
  • Bright and vibrant display (1330 nits)
  • Excellent battery endurance

  • Higher price tag
  • May lack expandable storage (unconfirmed)
  • Potentially smaller display size

Display Comparison

The OnePlus Nord 5 boasts a significantly brighter display, peaking at 1330 nits, compared to the Galaxy M31’s unspecified brightness. This translates to vastly improved visibility outdoors. While the M31’s panel size isn’t specified, the Nord 5’s superior brightness and likely higher contrast ratio (given its newer technology) offer a more immersive viewing experience. The Nord 5’s display technology is likely AMOLED, offering vibrant colors, while the M31 likely uses an IPS LCD panel.

Camera Comparison

Without detailed camera specifications for the M31 beyond its market segment, a direct comparison is limited. However, the OnePlus Nord 5 is expected to feature a more advanced camera system, leveraging the image signal processor (ISP) within the Snapdragon 8s Gen 3. The ISP enables faster image processing, improved low-light performance, and potentially more sophisticated computational photography features. The M31 likely relies on older image processing algorithms, resulting in less detail and dynamic range in challenging conditions. The absence of OIS information for the M31 suggests it may lack optical image stabilization, further disadvantaging it in low-light scenarios.

Performance

The core difference lies in the chipsets. The Samsung Galaxy M31’s Exynos 9611 (10nm) is a capable but aging processor, utilizing a mix of Cortex-A73 and A53 cores. The OnePlus Nord 5’s Snapdragon 8s Gen 3 (4nm) represents a massive leap forward. The 4nm process node provides significantly better power efficiency, reducing thermal throttling during sustained workloads. The Nord 5’s CPU configuration – a Cortex-X4 prime core alongside A720 and A520 cores – delivers substantially higher single-core and multi-core performance. This will be noticeable in everything from app launch times to demanding games.

Battery Life

The OnePlus Nord 5’s battery endurance of 49:12h and active use score of 13:47h demonstrate superior efficiency, despite potentially having a similar capacity to the M31 (which is not specified). The key differentiator is the charging speed. The Nord 5’s 80W wired charging, alongside 33W PPS and 18W PD support, can fully charge the device in just 54 minutes. The M31’s 15W charging is significantly slower, requiring considerably longer to reach a full charge. The Nord 5 also offers 5W reverse wired charging, a feature absent on the M31.

Buying Guide

Buy the Samsung Galaxy M31 if you prioritize extreme budget-friendliness and a large display for media consumption, accepting compromises in performance and charging speed. Buy the OnePlus Nord 5 if you demand a smooth, responsive experience for gaming and demanding apps, and value the convenience of incredibly fast charging and a brighter, more modern display.

Frequently Asked Questions

❓ Does the Exynos 9611 in the Galaxy M31 overheat during prolonged gaming sessions?
The Exynos 9611 is known to throttle under sustained load due to its 10nm process node and less efficient thermal design. Expect frame rate drops and reduced performance during extended gaming sessions, particularly with graphically demanding titles.
❓ How does the 80W charging on the OnePlus Nord 5 impact long-term battery health?
While 80W charging is incredibly fast, OnePlus implements intelligent charging algorithms to minimize battery degradation. The Nord 5 supports bypass charging, allowing you to power the device directly from the charger, reducing heat buildup and extending battery lifespan. The battery is also rated for 1200 cycles, indicating a robust design.
❓ Is the difference in chipset performance between the Exynos 9611 and Snapdragon 8s Gen 3 noticeable in everyday tasks?
Yes, the difference is substantial. While the M31 is adequate for basic tasks like browsing and social media, the Nord 5’s Snapdragon 8s Gen 3 provides a much smoother and more responsive experience, especially when multitasking or launching demanding applications.
❓ Does the OnePlus Nord 5 support high refresh rate gaming, like 90fps in PUBG?
The Snapdragon 8s Gen 3 is capable of driving high refresh rates in many games, including PUBG. However, achieving 90fps will depend on the game’s settings and optimization. The Nord 5’s powerful GPU and efficient cooling system provide a strong foundation for a smooth gaming experience.
