after updating to iOS 17.4, you get 15W wireless charging.

Good news for iPhone 12 owners: 15W wireless charging is now available thanks to iOS 17.4. Rare technical improvement after marketing.

Apple iPhone 12 users can rejoice: thanks to the iOS 17.4 update, their smartphone can now benefit from 15W wireless charging.

Technical development of a smartphone after its release is quite rare, and this software update offers a welcome improvement for iPhone 12 owners.

MagSafe and Qi 2 technology: the same thing, except for some details

In recent years, Apple has introduced MagSafe, Qi wireless charging coupled with a fairly powerful magnet on the back of the phone. This technology has made it possible to double the classic Qi wireless charging (7.5 W).

With the introduction of Qi 2, wireless charging becomes even more efficient, offering 15W of power. In a way, Qi 2 is MagSafe for everyone.

At the moment, no Android smartphone uses this technology, but the first accessories are already available on the market.

Thus, Apple, already compatible with Qi 2, allows the iPhone 12 to benefit from this improvement through a simple software update. iPhone 13, 14 and 15 have already benefited from this fast charging.

iPhone 12, special case

This update makes iPhone 12 the only iPhone model that supports MagSafe, but does not have the benefit of faster charging when using Qi 2 accessories. With iOS 17.4, this anomaly has now been corrected and iPhone 12 users can take full advantage of 15W wireless charging with using a compatible accessory.
