Display Comparison

Both phones feature displays that are adequate for everyday use, but detailed specifications are limited for the iPhone 12. The iPhone 12 boasts an infinite (nominal) contrast ratio, typical of OLED panels, providing deep blacks and vibrant colors. The OnePlus 9RT’s display specifications are not provided, but OnePlus typically prioritizes high refresh rates in this segment. The iPhone 12’s display benefits from Apple’s color calibration, ensuring accuracy for content creation. The lack of refresh rate information for the 9RT means it may not be as smooth for scrolling and gaming as some competitors.

Camera Comparison

Both phones offer capable camera systems, but specifics are limited. The iPhone 12’s camera is known for its consistent image quality and excellent video recording capabilities. The OnePlus 9RT’s camera specifications are not detailed, but OnePlus often focuses on delivering vibrant, social media-ready images. Without sensor size or aperture information for the 9RT, it’s difficult to assess its low-light performance relative to the iPhone 12. The iPhone 12’s video capabilities are likely superior due to Apple’s advanced image signal processing.

Performance

The core difference lies in the chipsets: Apple’s A14 Bionic (5nm) versus Qualcomm’s Snapdragon 888 5G (5nm). The A14 Bionic utilizes a hexa-core architecture (2x3.1 GHz Firestorm + 4x1.8 GHz Icestorm), while the Snapdragon 888 employs an octa-core configuration (1x2.84 GHz Cortex-X1 & 3x2.42 GHz Cortex-A78 & 4x1.80 GHz Cortex-A55). While the Snapdragon 888 has more cores, the A14 Bionic’s architecture is optimized for efficiency and single-core performance, often resulting in smoother app launches and responsiveness. The 5nm fabrication process is shared, suggesting comparable power efficiency, but the A14’s design gives it an edge in sustained performance. The OnePlus 9RT benefits from potentially more aggressive thermal management to sustain peak performance.

Battery Life

The iPhone 12 has an endurance rating of 84 hours, indicating solid battery life. It supports wired charging via PD2.0 (50% in 30 min) and 15W wireless charging with MagSafe and Qi2 (requires iOS 17.4). The OnePlus 9RT 5G shines with its 65W wired charging, achieving a 100% charge in just 29 minutes. While the iPhone 12 offers wireless charging convenience, the 9RT’s significantly faster wired charging is a major advantage for users who prioritize quick top-ups. The iPhone 12’s longer endurance rating suggests it may last longer on a single charge under moderate use, but the 9RT’s charging speed mitigates this difference.

Buying Guide

Buy the Apple iPhone 12 if you need a phone with guaranteed software updates for years to come, a tightly integrated ecosystem of devices, and a strong resale value. Buy the OnePlus 9RT 5G if you prefer faster charging speeds, a more customizable Android experience, and are looking for maximum performance per dollar, even if it means a shorter software support lifespan.

Frequently Asked Questions

❓ Does the Snapdragon 888 in the OnePlus 9RT 5G suffer from overheating issues during prolonged gaming sessions?
The Snapdragon 888 is known to generate heat under sustained load. However, OnePlus typically implements robust thermal management solutions, including vapor chambers and optimized software, to mitigate throttling. While some heat is expected during extended gaming, the 9RT is generally capable of maintaining acceptable performance levels.
❓ How does the iPhone 12’s software update policy compare to the OnePlus 9RT 5G?
Apple provides significantly longer software support for its iPhones. The iPhone 12 continues to receive major iOS updates and security patches for many years after its release. The OnePlus 9RT 5G, being an Android device, typically receives 2-3 years of major Android updates and 3-4 years of security patches, a considerably shorter timeframe than the iPhone 12.
❓ Is MagSafe on the iPhone 12 worth the investment for wireless charging?
MagSafe offers convenient and secure wireless charging, and allows for the attachment of accessories like wallets and stands. However, it's limited to 15W charging speeds, which isn't significantly faster than standard Qi wireless charging. The convenience and accessory ecosystem are the primary benefits of MagSafe.
