Display Comparison

The iPhone 12 Mini boasts a measured peak brightness of 627 nits, offering excellent visibility in bright sunlight. While the Aquos R2 Compact’s brightness isn’t specified, its OLED panel likely delivers vibrant colors. However, the iPhone’s infinite contrast ratio, typical of OLED displays, provides deeper blacks and a more dynamic image. Both devices likely utilize similar OLED technology, but Apple’s display calibration and color accuracy are generally considered superior. The iPhone 12 Mini’s smaller size (5.4 inches vs. the R2 Compact’s 5.2 inches) contributes to a higher pixel density, resulting in a sharper image.

Camera Comparison

Both devices offer capable camera systems, but Apple’s image processing pipeline gives the iPhone 12 Mini an edge. While both are described as offering 'Photo / Video' capabilities, the iPhone benefits from Apple’s computational photography expertise, delivering consistently excellent results in various lighting conditions. Sensor sizes are not specified for either device, but Apple’s software algorithms compensate for potential hardware limitations. The Aquos R2 Compact likely relies more heavily on hardware capabilities, which, while good for its time, are now surpassed by the iPhone 12 Mini’s software-driven enhancements.

Performance

The core difference lies in the chipsets. The Apple A14 Bionic, fabricated on a 5nm process, significantly outperforms the Qualcomm Snapdragon 845 (10nm) in both CPU and GPU performance. The A14’s hexa-core architecture (2x3.1 GHz Firestorm + 4x1.8 GHz Icestorm) is more efficient than the Snapdragon 845’s octa-core configuration (4x2.6 GHz Kryo 385 Gold & 4x1.7 GHz Kryo 385 Silver). While the Snapdragon 845 was a flagship chip in its time, the A14’s architectural advantages and smaller node size translate to better sustained performance and thermal management. This means the iPhone 12 Mini is less likely to throttle under heavy loads, providing a smoother gaming and multitasking experience.

Battery Life

Interestingly, both phones achieve an endurance rating of 69 hours, despite the Aquos R2 Compact’s battery capacity being unspecified. This suggests the A14 Bionic’s superior power efficiency offsets any potential capacity difference. The Aquos R2 Compact supports 18W wired charging with PD2.0, offering faster charging speeds than the iPhone 12 Mini’s 15W wired charging (also PD2.0). The iPhone 12 Mini also adds 15W wireless charging via MagSafe and Qi2 (with iOS 17.4), a feature absent on the Aquos R2 Compact. While the R2 Compact charges faster initially, the iPhone’s wireless charging options provide added convenience.

Buying Guide

Buy the Sharp Aquos R2 Compact if you prioritize a more open Android ecosystem, faster wired charging (18W vs iPhone's 15W), and are comfortable with a device that is no longer receiving software updates. Buy the Apple iPhone 12 Mini if you value seamless iOS integration, guaranteed software updates for several years, and a more polished camera experience, even if it means slightly slower charging speeds.

Frequently Asked Questions

❓ Is the Sharp Aquos R2 Compact still secure to use in 2024, given its age?
No. The Aquos R2 Compact is no longer receiving security updates from Sharp. Using it with sensitive information carries a significant risk. While it may function, it's vulnerable to known exploits and malware.
❓ Does the iPhone 12 Mini's battery hold up well after several years of use?
The iPhone 12 Mini's battery health degrades over time, as with all lithium-ion batteries. However, Apple's battery health management features help mitigate this. Users can check their battery health in Settings and consider a battery replacement if capacity falls below 80%.
❓ Can I use fast charging with either phone if I don't have a PD2.0 charger?
Both phones support PD2.0, but will charge at slower speeds with a non-PD charger. While they will still charge with standard USB chargers, you won't achieve the advertised 18W or 15W charging speeds.
❓ Is the Aquos R2 Compact a good option for custom ROMs?
The Aquos R2 Compact has a small but active community of developers working on custom ROMs. This can breathe new life into the device and offer features not available in the stock software, but it requires technical expertise and carries inherent risks.
