  • Lower peak display brightness

Display Comparison

The Samsung Galaxy S20 Ultra 5G features a display capable of reaching 894 nits of peak brightness, noticeably exceeding the iPhone 11 Pro Max’s 820 nits. This translates to better visibility in direct sunlight. While both displays offer excellent quality, Samsung’s higher peak brightness is a tangible advantage for outdoor use. The iPhone 11 Pro Max, however, boasts an 'infinite' contrast ratio, delivering deep blacks and vibrant colors, a hallmark of Apple’s OLED technology. Neither device specifies refresh rate, but both are 60Hz panels.

Camera Comparison

Both phones excel in camera performance, but approach it differently. Both are capable of Photo and Video. The S20 Ultra’s camera system, while boasting more megapixels (not specified in data), relies heavily on software processing. The iPhone 11 Pro Max prioritizes natural-looking images with accurate color reproduction. The S20 Ultra’s larger sensor (implied by its 'Ultra' designation) allows for better low-light performance, but can sometimes produce over-sharpened images. The iPhone’s video recording is consistently praised for its stability and dynamic range. The lack of detail regarding specific lens apertures and sensor sizes beyond the main sensor makes a precise comparison difficult.

Performance

The performance landscape is more nuanced. The iPhone 11 Pro Max’s Apple A13 Bionic (7nm+) is a hexa-core chip known for its efficiency and single-core performance. The S20 Ultra 5G comes in two variants: the Exynos 990 (Global) and the Snapdragon 865 (USA). The Snapdragon variant, with its Cortex-A77 cores, offers a performance edge over the Exynos version. However, the A13 Bionic consistently outperforms both Exynos and Snapdragon in real-world tasks and benchmarks, due to Apple’s tight hardware-software integration. The S20 Ultra’s 4GB of RAM (versus the iPhone’s 4GB) is a potential bottleneck, especially with Android’s more memory-intensive nature.

Battery Life

Battery life is where the iPhone 11 Pro Max truly shines. Its endurance rating of 102 hours significantly surpasses the S20 Ultra 5G’s 87 hours. While the S20 Ultra offers significantly faster charging – 45W wired with PD3.0 versus the iPhone’s wired PD2.0 and 50% in 30 minutes – the iPhone’s superior efficiency means you’ll spend less time tethered to a charger. The S20 Ultra also includes 15W wireless charging and 4.5W reverse wireless charging, features absent on the iPhone 11 Pro Max.

Buying Guide

Buy the Samsung Galaxy S20 Ultra 5G if you need a display with maximum brightness for outdoor visibility and prioritize the fastest possible charging speeds. It’s ideal for users who frequently capture photos and videos and appreciate the flexibility of Android. Buy the Apple iPhone 11 Pro Max if you prefer a consistently smooth and efficient experience, exceptional battery life, and a mature, well-integrated ecosystem. It’s the better choice for users who value simplicity and long-term software support.

Frequently Asked Questions

❓ Does the Exynos 990 chip in the S20 Ultra 5G overheat during prolonged gaming sessions?
The Exynos 990 variant of the S20 Ultra 5G is known to be more prone to thermal throttling than the Snapdragon 865 version, especially during demanding tasks like extended gaming. While not a complete deal-breaker, users should expect some performance reduction after prolonged use. The iPhone 11 Pro Max’s A13 Bionic is significantly more efficient and less susceptible to overheating.
❓ Is the 2MP macro camera on the S20 Ultra 5G actually useful for detailed close-up shots?
The 2MP macro camera on the S20 Ultra 5G, like many macro cameras of its era, is largely a marketing feature. The low resolution results in images lacking detail and sharpness. It's generally better to utilize the main sensor and crop for close-up shots, yielding superior results.
❓ Can the Samsung Galaxy S20 Ultra 5G reliably maintain 60fps in graphically intensive games like PUBG?
The S20 Ultra 5G, particularly the Snapdragon variant, can generally maintain 60fps in PUBG, but may experience occasional frame drops during intense action sequences. The Exynos version is more likely to exhibit noticeable frame rate fluctuations. The iPhone 11 Pro Max’s A13 Bionic provides a more consistently smooth gaming experience.
❓ How does the iPhone 11 Pro Max's software support compare to the S20 Ultra 5G?
Apple provides significantly longer software support for its devices. The iPhone 11 Pro Max continues to receive iOS updates, ensuring security and feature enhancements. Samsung’s software support for the S20 Ultra 5G is more limited, with fewer major Android updates guaranteed.
