Samsung Galaxy Note20 Ultra 5G

  • Integrated S Pen stylus for productivity and creativity
  • Expandable storage via microSD card
  • Higher peak display brightness for outdoor visibility

  • Exynos 990 variant can suffer from thermal throttling
  • More aggressive image processing may not appeal to all users
  • Android software support is shorter than iOS

Apple iPhone 12 Pro Max

  • Exceptional performance and power efficiency with the A14 Bionic
  • Long-term software support from Apple
  • Consistent and natural camera image quality

  • No expandable storage
  • No included stylus
  • Lower peak display brightness compared to Note20 Ultra

Display Comparison

The Note20 Ultra boasts a measured peak brightness of 1024 nits, exceeding the iPhone 12 Pro Max’s 822 nits. This translates to better visibility in direct sunlight. Both displays share an 'Infinite' (nominal) contrast ratio, indicating excellent black levels. While both are excellent, the Note20 Ultra’s higher peak brightness provides a tangible advantage for outdoor use. The Note20 Ultra's 120Hz refresh rate (not mentioned in the data, but a key feature) provides smoother scrolling and animations compared to the iPhone's standard 60Hz, though this comes at a battery cost.

Camera Comparison

Both phones excel in photography and videography, but approach it differently. The iPhone 12 Pro Max is known for its natural color science and consistent image quality across all lenses. The Note20 Ultra, while capable of stunning photos, often employs more aggressive image processing, resulting in punchier colors. Both offer excellent video recording capabilities. Without specific sensor size data, it’s difficult to definitively declare a winner, but the iPhone’s computational photography and video stabilization are generally considered best-in-class. The Note20 Ultra's versatility with features like Space Zoom (not mentioned in the data, but a key feature) provides options the iPhone lacks.

Performance

The performance landscape is complex. The iPhone 12 Pro Max’s Apple A14 Bionic, fabricated on a 5nm process, offers a significant efficiency advantage over both versions of the Note20 Ultra’s chipset. The Note20 Ultra shipped with either the Exynos 990 (7nm+) globally or the Snapdragon 865 5G+ (7nm+) in the USA. While the Snapdragon variant is superior to the Exynos, both are prone to more thermal throttling under sustained load than the A14 Bionic. The A14’s hexa-core architecture (2x3.1 GHz Firestorm + 4x1.8 GHz Icestorm) is optimized for both peak performance and power efficiency. The Note20 Ultra’s octa-core configuration, while offering more cores, doesn’t translate to consistently faster real-world performance.

Battery Life

Both devices achieve an endurance rating of approximately 90 hours, with the iPhone 12 Pro Max slightly edging out the Note20 Ultra at 95 hours. The iPhone 12 Pro Max benefits from the A14 Bionic’s superior power efficiency. While the Note20 Ultra supports 25W wired charging with PD3.0, the iPhone 12 Pro Max offers 20W wired charging with PD2.0, reaching 50% charge in 30 minutes. Both support 15W wireless charging, but the iPhone leverages MagSafe for a more secure and efficient connection. The Note20 Ultra also offers 4.5W reverse wireless charging, a feature absent on the iPhone.

Buying Guide

Buy the Samsung Galaxy Note20 Ultra 5G if you need a versatile device for productivity, value the S Pen stylus for note-taking and creative tasks, and require expandable storage. Buy the Apple iPhone 12 Pro Max if you prioritize a seamless user experience, long-term software support, and a consistently excellent camera system, even if it means sacrificing expandable storage and stylus functionality.

Frequently Asked Questions

❓ Does the Exynos 990 chip in the global Note20 Ultra overheat during extended gaming sessions?
Yes, the Exynos 990 variant is known to throttle under sustained load, leading to reduced performance during prolonged gaming. The Snapdragon 865+ version performs better, but still doesn't match the A14 Bionic's thermal efficiency. Users should expect some performance degradation after 30-45 minutes of intensive gaming.
❓ Is the 15W wireless charging with MagSafe on the iPhone 12 Pro Max significantly faster than the Note20 Ultra's 15W Qi wireless charging?
Yes, MagSafe offers a more consistent and efficient wireless charging experience. The magnetic alignment ensures optimal coil positioning, resulting in faster charging speeds and reduced energy loss compared to the Note20 Ultra's standard Qi wireless charging.
❓ How does the software update support compare between the Note20 Ultra and the iPhone 12 Pro Max?
Apple provides significantly longer software support for its iPhones. The iPhone 12 Pro Max will continue to receive major iOS updates for several years, while the Note20 Ultra's Android updates are nearing their end. This impacts security and access to new features.
❓ Is the S Pen on the Note20 Ultra worth the extra cost for someone who doesn't typically use a stylus?
The S Pen is a unique feature that can be surprisingly useful even for casual users. It allows for precise navigation, handwriting recognition, and remote control functionality. However, if you're certain you won't utilize these features, the iPhone 12 Pro Max offers a more streamlined experience.
