Display Comparison

Both the Oppo Reno3 Pro 5G and iPhone 12 Pro Max boast 'Infinite' (nominal) contrast ratios, indicative of OLED panels. However, the iPhone 12 Pro Max edges out the Reno3 Pro with a measured peak brightness of 822 nits versus 819 nits. While the difference is minimal, it could be noticeable in direct sunlight. Both displays offer excellent viewing angles and color reproduction, but Apple’s color calibration is generally considered more accurate. The Reno3 Pro’s display technology isn’t specified beyond OLED, while the iPhone 12 Pro Max benefits from Apple’s Super Retina XDR display, known for its dynamic range.

Camera Comparison

Both phones offer capable camera systems, but approach image processing differently. While both are listed as capable of Photo/Video, the iPhone 12 Pro Max likely benefits from Apple’s computational photography expertise and larger sensor size (though specific sensor sizes aren’t provided). The Reno3 Pro’s camera performance is respectable, but it likely won’t match the iPhone’s dynamic range and detail in challenging lighting conditions. The iPhone’s video recording capabilities are also superior, with features like Dolby Vision HDR recording. The Reno3 Pro’s camera system likely relies more heavily on software processing to enhance image quality.

Performance

The performance gap is significant. The iPhone 12 Pro Max’s Apple A14 Bionic, fabricated on a 5nm process, delivers substantially more processing power than the Oppo Reno3 Pro 5G’s Qualcomm Snapdragon 765G (7nm). The A14’s hexa-core architecture, with two high-performance Firestorm cores clocked at 3.1 GHz, dwarfs the Snapdragon 765G’s octa-core configuration. This translates to faster app loading times, smoother multitasking, and superior gaming performance on the iPhone. While the Snapdragon 765G is capable for everyday tasks, the A14 Bionic offers a future-proofed experience. The iPhone also benefits from 6GB of RAM, matching the Reno3 Pro, but the A14’s efficiency allows it to manage memory more effectively.

Battery Life

Endurance ratings show a slight edge to the Oppo Reno3 Pro 5G at 100 hours versus the iPhone 12 Pro Max’s 95 hours. However, this doesn’t tell the whole story. The iPhone 12 Pro Max offers faster charging with a 50% charge in 30 minutes, while the Reno3 Pro achieves 50% in 20 minutes with its 30W wired charging. The iPhone also supports 15W wireless charging (MagSafe and Qi2 with iOS 17.4), a feature absent on the Reno3 Pro. The A14 Bionic’s power efficiency also contributes to real-world battery performance, potentially offsetting the slightly smaller battery capacity.

Buying Guide

Buy the Oppo Reno3 Pro 5G if you need a capable 5G phone with a bright display and fast 30W charging, and prioritize value over absolute performance. You'll benefit from a more open Android ecosystem and a lower upfront cost. Buy the Apple iPhone 12 Pro Max if you prefer a seamless iOS experience, unmatched processing power with the A14 Bionic, and a premium camera system, and are willing to pay a premium for it.

Frequently Asked Questions

❓ Does the Snapdragon 765G in the Oppo Reno3 Pro 5G struggle with demanding games like Genshin Impact?
While the Snapdragon 765G can run Genshin Impact, you'll likely need to lower the graphics settings to medium or low to maintain a stable frame rate. The iPhone 12 Pro Max’s A14 Bionic will handle Genshin Impact at maximum settings with ease.
❓ Is the iPhone 12 Pro Max still receiving software updates and security patches?
Yes, the iPhone 12 Pro Max continues to receive regular software updates and security patches from Apple, ensuring it remains secure and up-to-date with the latest features. Oppo’s software support for the Reno3 Pro 5G is likely more limited at this point.
❓ How does the 5G performance differ between the Oppo Reno3 Pro 5G and the iPhone 12 Pro Max?
Both devices support 5G, but the iPhone 12 Pro Max generally has wider 5G band support, potentially leading to better connectivity in more regions. The A14 Bionic’s modem is also more efficient, potentially resulting in better battery life while using 5G.
