iOS 17.4 brings Qi2 charging to iPhone 12

Apple has enhanced the iPhone 12 with Qi2 wireless charging support, a feature that arrived unannounced with the iOS 17.4 update. This quiet addition is a significant upgrade for iPhone 12 users, who can now harness the full potential of Qi2-certified chargers recently introduced to the market. These chargers incorporate the magnetic attachment and 15W charging speeds synonymous with Apple's proprietary MagSafe technology.

The iPhone 12's journey began in 2020, marking a pivotal moment as Apple's first phone to integrate MagSafe, a technology that allowed for 15W magnetic charging. This was a leap forward from the standard Qi wireless charging, which was capped at 7.5W for iPhones. The MagSafe feature not only offered faster charging but also introduced a new ecosystem of accessories that magnetically snapped onto the back of the phone, providing both convenience and a secure fit.

With the advent of Qi2, the iPhone 12's capabilities have been further expanded. Qi2 is the next evolution of wireless charging, offering a universal standard that includes the benefits of MagSafe's magnetic alignment and optimized charging speeds. This update is particularly noteworthy because it retroactively adds new functionality to an existing device, extending its lifespan and utility.


The transition to Qi2 began with the iPhone 13 and 14, which received support for the standard as part of the iOS 17.2 update. The iPhone 15, on the other hand, was Qi2-ready right out of the box. This strategic rollout ensured a seamless user experience across multiple generations of iPhones, culminating in the update that brought the iPhone 12 into the Qi2 fold.

This development is more than just a technical enhancement; it's a testament to Apple's commitment to backward compatibility and customer satisfaction. By quietly updating the iPhone 12, Apple has ensured that its customers can continue to enjoy the latest technological advancements without the need to purchase new hardware. It's a move that reinforces the company's dedication to sustainability and its recognition of the importance of a robust accessory ecosystem.

Moreover, the update aligns with the growing trend of technology companies focusing on environmental responsibility. By enhancing the functionality of older devices, Apple is indirectly contributing to the reduction of electronic waste, encouraging users to hold onto their devices for longer periods.
