Good news for Apple iPhone 12 users: You can experience 15W wireless charging after upgrading to iOS 17.4

According to Macworld reports on March 28, iOS 17.4 brings the function of 15W wireless charging using the Qi2 standard to the iPhone 12.

Qi2 is the next generation of wireless charging technology designed by the Wireless Power Consortium (WPC) and is based on MagSafe technology. MagSafe debuts on iPhone 12, offering charging speeds of up to 15W. However, third-party wireless chargers that are not MagSafe-certified can only offer charging speeds of up to 7.5W, while Qi2 can achieve the full 15W. Noted that last year Apple added the function of 15W charging using Qi2 wireless chargers to iPhone 13 and iPhone 14 through the iOS 17.2 update, and the iPhone 15 series natively supported the Qi2 standard when it was released. This makes the iPhone 12 the only iPhone model to support MagSafe but not enjoy faster charging when using Qi2 accessories. Macworld cited user feedback and self-test results saying that when the iPhone 12 is updated to iOS 17.4, it can achieve 15W charging speeds using a Qi2 wireless charger. At this point, the device displays the same animation as 15W charging, and tests using the Anker Qi2 MagGo wireless charger achieved similar charging speeds to MagSafe. Apple officials once claimed that iOS 17.2 added Qi2 support for iPhone 13 and iPhone 14, but did not make similar statements for iOS 17.4 and iPhone 12. This may be because the iPhone 12's wireless charging technology is based on the original Qi standard and MagSafe design, and the Qi2 standard was not finalized at that time.
