Display Comparison

The iPhone 12 Pro Max boasts a measured peak brightness of 822 nits, providing excellent visibility outdoors. While the S21 Pro’s display specs are not provided, vivo typically equips its 'Pro' models with vibrant AMOLED panels. The iPhone’s infinite contrast ratio (nominal) delivers deep blacks and vivid colors. However, the lack of LTPO technology on the iPhone 12 Pro Max means it’s limited to a 60Hz refresh rate, while many modern Android phones, including likely the S21 Pro, offer adaptive refresh rates for smoother scrolling and animations. This difference impacts the perceived fluidity of the user experience.

Camera Comparison

Both devices are described as having capable photo/video systems, but specifics are limited. The iPhone 12 Pro Max is known for its excellent image processing and cinematic mode for video recording. Without sensor size or aperture details for the S21 Pro, it’s difficult to make a direct comparison. However, modern vivo phones often prioritize high megapixel counts and advanced computational photography. The iPhone’s strength lies in its consistent, natural-looking images, while the S21 Pro may lean towards more vibrant, processed results. The absence of detailed camera specs for the S21 Pro makes a definitive judgment impossible.

Performance

The Mediatek Dimensity 9300+ in the vivo S21 Pro, fabricated on a 4nm process, represents a significant leap in mobile processing. Its octa-core configuration, featuring Cortex-X4 cores, is designed for sustained peak performance. In contrast, the Apple A14 Bionic (5nm) utilizes a hexa-core design. While the A14 remains a potent chip, the Dimensity 9300+’s newer architecture and higher clock speeds (3.25 GHz vs 3.1 GHz) suggest a performance advantage in CPU-intensive tasks. The S21 Pro’s likely use of LPDDR5x RAM further enhances memory bandwidth compared to the iPhone 12 Pro Max’s LPDDR4. Thermal management will be key; the 4nm node of the Dimensity 9300+ should offer better efficiency, but sustained loads will reveal its true capabilities.

Battery Life

The iPhone 12 Pro Max achieved an endurance rating of 95 hours, indicating excellent battery life for its time. The S21 Pro’s battery capacity is not specified, but its 90W wired charging is a game-changer. This allows for a full charge in a fraction of the time compared to the iPhone’s 50% charge in 30 minutes via PD2.0. While the iPhone supports 15W wireless charging (MagSafe/Qi2), the S21 Pro also offers reverse wired charging, adding to its versatility. The faster charging speed of the S21 Pro effectively mitigates any potential disadvantage from a smaller battery capacity.

Buying Guide

Buy the vivo S21 Pro if you prioritize blazing-fast charging, cutting-edge processor performance for demanding tasks, and value for money. It’s ideal for power users, gamers, and those who frequently transfer large files. Buy the Apple iPhone 12 Pro Max if you prefer the seamless integration of the iOS ecosystem, long-term software support, and a proven track record of reliability, and are willing to pay a premium for it.

Frequently Asked Questions

❓ Does the Mediatek Dimensity 9300+ in the vivo S21 Pro overheat during prolonged gaming sessions?
The Dimensity 9300+ is built on a 4nm process, which generally offers improved thermal efficiency compared to older nodes. While sustained gaming will inevitably generate heat, the S21 Pro should be able to maintain performance for extended periods without significant throttling, especially with a well-designed cooling system. Real-world testing will be needed to confirm its thermal performance under heavy load.
❓ How does the iPhone 12 Pro Max’s software support compare to the vivo S21 Pro?
Apple provides significantly longer software support for its iPhones. The iPhone 12 Pro Max will continue to receive iOS updates for several years, ensuring security patches and new features. Vivo’s software support is typically shorter, with fewer major Android updates guaranteed. This is a key consideration for users who prioritize long-term usability and security.
❓ Is the difference in charging speed between the vivo S21 Pro and iPhone 12 Pro Max truly noticeable in everyday use?
Absolutely. The S21 Pro’s 90W charging can fully charge the device in under 40 minutes, while the iPhone 12 Pro Max takes considerably longer. This difference is particularly impactful for users who frequently find themselves with low battery and need a quick top-up before heading out.
