The iOS 17.4 update suddenly brought good news to iPhone 12 users

Accordingly, the iOS 17.4 update brought 15W wireless charging function using the Qi2 standard to iPhone 12. This is a significant advancement in line with MagSafe's advanced technology.

The Wireless Power Consortium (WPC) designed the Qi2 standard as the next generation of wireless charging technology, inspired by Apple's MagSafe technology. First introduced with the iPhone 12, MagSafe enabled charging speeds of up to 15W, setting a new standard for wireless charging efficiency for iPhone users at the time. However, third-party wireless chargers without MagSafe certification are limited to 7.5W speeds. The Qi2 standard now allows iPhone 12 users to use the full 15W power supply, revolutionizing their charging experience.

Apple's strategic updates have gradually expanded the scope of Qi2 support across its iPhone line. First, iOS 17.2 expands Qi2 wireless charging capabilities to iPhone 13 and 14 users. The iPhone 15 series already supported the Qi2 standard upon release. However, the iPhone 12 is the only model that supports MagSafe without the enhanced charging speeds offered by the Qi2 accessory.

Following the iOS 17.4 update, iPhone 12 users can now enjoy the benefits of 15W charging speeds when using a Qi2 wireless charger. User feedback and MacWorld's comprehensive testing have confirmed the effectiveness of this update, demonstrating charging speeds comparable to MagSafe. The device displays a special animation indicating the 15W charging level, confirming the successful integration of Qi2 technology into the charging capabilities of the iPhone 12.

In short, the iOS 17.4 update marks an important milestone for iPhone 12 users, ushering in a new era of wireless charging efficiency and convenience. With the seamless integration of the Qi2 standard, Apple continues to prioritize innovation and user experience, ensuring that iPhone users stay at the forefront of cutting-edge technology.
