  • Compact and pocketable design
  • Superior display contrast ratio (1544:1)

  • Significantly shorter battery life (59h endurance)
  • Limited 5G support

Display Comparison

The Galaxy A51 5G boasts a larger display, achieving a peak brightness of 642 nits, while the iPhone SE (2020) reaches 670 nits. However, the iPhone SE’s display exhibits a significantly higher contrast ratio of 1544:1 compared to the A51 5G’s ‘infinite’ (nominal) ratio, resulting in richer blacks and more vibrant colors. While both displays are capable, the iPhone SE’s superior contrast provides a more visually engaging experience, despite its smaller size. The A51 5G’s larger size is beneficial for media consumption, but the iPhone SE’s color accuracy is likely superior, typical of Apple’s displays.

Camera Comparison

Both phones offer photo and video capabilities, but details are limited. The iPhone SE (2020) benefits from Apple’s renowned image processing algorithms, delivering consistently good results in various lighting conditions. The Galaxy A51 5G likely relies more on software enhancements to compensate for potentially less advanced hardware. Without specific sensor size or aperture information, it’s difficult to definitively declare a winner, but Apple’s track record suggests a slight edge in overall image quality and video stabilization. The A51 5G may offer more versatility with potentially wider angle or macro lenses (though not specified), but the iPhone SE’s simplicity and consistent performance are compelling.

Performance

The core difference lies in the chipsets. The iPhone SE (2020) is powered by the Apple A13 Bionic (7nm+), a hexa-core processor known for its exceptional single-core performance. The Galaxy A51 5G utilizes the Exynos 980 (8nm). While the Exynos 980 is an octa-core processor, the A13 Bionic’s architecture and manufacturing process give it a substantial performance advantage. This translates to faster app loading times, smoother multitasking, and superior gaming performance on the iPhone SE. The A13’s 7nm+ process also contributes to better thermal efficiency, potentially reducing throttling during sustained workloads.

Battery Life

Battery life is a clear win for the Samsung Galaxy A51 5G, with an endurance rating of 90 hours compared to the iPhone SE (2020)’s 59 hours. This difference is significant and reflects the A51 5G’s larger battery capacity. While the iPhone SE (2020) supports 18W wired charging (50% in 30 minutes) and 7.5W wireless charging, the A51 5G’s longer endurance mitigates the slower 15W wired charging. For users who frequently use their phones throughout the day, the A51 5G offers considerably more peace of mind.

Buying Guide

Buy the Samsung Galaxy A51 5G if you need extended battery life, 5G access, and a larger screen for media consumption. It’s a solid all-rounder for everyday tasks and casual gaming. Buy the Apple iPhone SE (2020) if you prefer a compact, pocketable phone with exceptional processing power for demanding apps and games, and you’re invested in the Apple ecosystem.

Frequently Asked Questions

❓ Does the Exynos 980 chip in the Galaxy A51 5G overheat during prolonged gaming sessions?
The Exynos 980 is an 8nm chip, which is reasonably efficient. However, it's not as thermally efficient as the A13 Bionic's 7nm+ process. While it won't likely cause severe overheating, users may experience some throttling during extended, graphically intensive gaming sessions, leading to a slight performance dip.
❓ Is the 18W charging on the iPhone SE (2020) significantly faster in real-world use compared to the A51 5G’s 15W charging?
Yes, the iPhone SE (2020) can charge from 0-50% in approximately 30 minutes with its 18W charger. The A51 5G’s 15W charging will take considerably longer to reach the same level. However, the A51 5G’s superior battery life means you’ll likely need to charge it less frequently.
❓ Does the iPhone SE (2020) support the latest 5G networks?
No, the iPhone SE (2020) does not support 5G. It is a 4G LTE device. The Samsung Galaxy A51 5G, as its name suggests, offers 5G connectivity, providing faster data speeds where available.
