Apple iPhone 12 Pro

  • Superior video recording quality
  • Long-term software support from Apple
  • Strong ecosystem integration

  • Shorter battery life compared to S21+
  • Slower charging speeds
  • Less vibrant display in direct sunlight

Samsung Galaxy S21+ 5G

  • Excellent battery endurance (114h rating)
  • Faster charging (25W wired)
  • Brighter display for outdoor visibility

  • Android update support is shorter than Apple's
  • Image processing can be overly saturated for some users
  • Potential for thermal throttling under heavy load

Display Comparison

The Samsung Galaxy S21+ 5G boasts a notably brighter display, peaking at 883 nits, compared to the iPhone 12 Pro’s ‘infinite’ (nominal) contrast ratio which doesn’t specify peak brightness. This translates to better outdoor visibility for the S21+. Both displays share an ‘infinite’ contrast ratio, suggesting excellent black levels, but the S21+’s higher peak brightness is a tangible advantage. While both are excellent, the S21+’s panel is more easily viewable in direct sunlight.

Camera Comparison

Both phones offer capable photo and video recording, but approach it differently. The iPhone 12 Pro is renowned for its cinematic mode and excellent video stabilization. While both phones have multiple lenses, the iPhone 12 Pro’s image processing tends towards natural colors, while Samsung’s leans towards more vibrant, saturated images. The S21+’s camera system benefits from Samsung’s advanced computational photography, but the iPhone 12 Pro’s video capabilities are generally considered superior. The lack of detailed sensor information makes a direct comparison difficult, but the iPhone’s video prowess is a key differentiator.

Performance

The iPhone 12 Pro’s Apple A14 Bionic (5nm) chip features a hexa-core CPU, while the Galaxy S21+ 5G utilizes either the Exynos 2100 (5nm - International) or Snapdragon 888 (5nm - USA/China). The A14 Bionic’s architecture, with its Firestorm and Icestorm cores, is optimized for single-core performance, often giving it an edge in everyday tasks. The S21+’s octa-core processor, particularly the Cortex-X1 core, aims for peak performance, but can be more prone to thermal throttling under sustained load. Both devices feature 6GB of RAM, but iOS’s memory management is generally more efficient, allowing the iPhone 12 Pro to maintain responsiveness with less RAM.

Battery Life

The Samsung Galaxy S21+ 5G significantly outperforms the iPhone 12 Pro in battery endurance, achieving a rating of 114 hours versus the iPhone’s 81 hours. This is a substantial difference, translating to a full day of heavy use for the S21+ compared to potentially needing a top-up for the iPhone 12 Pro. The S21+ also supports 25W wired charging with PD3.0, allowing for a faster 0-100% charge than the iPhone 12 Pro’s 50% in 30 minutes via PD2.0. The iPhone 12 Pro offers 15W wireless charging with MagSafe and Qi2 (with iOS 17.4), while the S21+ provides 15W Qi wireless and 4.5W reverse wireless charging.

Buying Guide

Buy the Apple iPhone 12 Pro if you need a tightly integrated ecosystem, prioritize video recording quality, and value Apple’s long-term software update commitment. Buy the Samsung Galaxy S21+ 5G if you prefer a brighter display, require significantly longer battery life, and appreciate the flexibility of Android with faster charging capabilities.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the international S21+ overheat during prolonged gaming sessions?
The Exynos 2100, while powerful, is known to generate more heat than the Snapdragon 888. Users have reported some thermal throttling during extended gaming, potentially leading to reduced performance. However, the S21+'s cooling system is adequate for most tasks, and throttling isn't usually severe enough to render games unplayable.
❓ Is the 2MP macro camera on the Galaxy S21+ actually useful for detailed close-up shots?
The 2MP macro camera on the S21+ is largely a marketing feature. Its low resolution results in images lacking detail and sharpness. While it can capture close-up shots, the quality is significantly inferior to the main sensor and doesn't offer a substantial benefit over digital zoom.
❓ Does the Galaxy S21+ support 90fps in popular games like PUBG Mobile?
The Galaxy S21+ can achieve frame rates close to 90fps in PUBG Mobile, but it depends on the graphics settings and the specific device variant (Snapdragon or Exynos). To maximize frame rates, you may need to lower the graphics settings to 'Smooth' or 'Balanced'. The phone's display supports a 120Hz refresh rate, but PUBG Mobile doesn't natively support this, so you won't see a full 120fps experience.
❓ How does MagSafe on the iPhone 12 Pro compare to wireless charging on the S21+?
MagSafe offers a more secure and aligned wireless charging experience on the iPhone 12 Pro, thanks to the magnetic attachment. While both phones support 15W wireless charging, MagSafe also enables accessories like wallets and car mounts. The S21+ uses standard Qi wireless charging, which is less secure and requires precise alignment.
