iPhone 12 Gains Qi2 Wireless Charging with iOS 17.4 Update

The unexpected upgrade enables faster, more efficient charging for the iPhone 12, marking a significant step towards standardizing wireless charging technology.

The iPhone 12 received an unannounced upgrade to support Qi2 wireless charging with the iOS 17.4 update, enabling faster charging speeds.
Qi2 wireless charging, developed with Apple's involvement, aims to standardize wireless charging across devices, including Android, by offering a magnetic connection and 15W charging speed.
Despite initial hopes, Samsung's decision to skip Qi2 support in its 2024 Galaxy S24 model has cast doubt on the standard's universal adoption.
A range of Qi2-compatible accessories, including chargers from Belkin and Anker, are now available, with more expected to launch soon.
Testing by MacWorld confirmed that the iPhone 12 can now charge at the full 15W speed with Qi2 chargers, matching the performance of Apple-certified MagSafe chargers.
