This iPhone line suddenly increased charging speed when updating to iOS 17.4

Those who are using the iPhone 12 generation should quickly update to iOS 17.4, because this version allows hardware unlocking for wireless charging capabilities. Specifically, iOS 17.4 allows the iPhone 12 series, including iPhone 12, iPhone 12 mini, iPhone 12 Pro and iPhone 12 Pro Max to increase wireless charging capacity to 15W with Qi2 standard. Qi2 is a new generation wireless charging technology from the Wireless Power Consortium (WPC) based on MagSafe. MagSafe officially introduced MagSafe charging technology to the iPhone 12 series with 15W charging capacity. However, 3rd party charging docks that are not MagSafe certified can only charge at a maximum speed of 7.5W, for Qi2, users can get the full 15W.

On iPhone 13 and iPhone 14, Apple has supported 15W wireless charging speed from iOS 17.2 version, iPhone 15 also supported Qi2 when it was launched. Until today, Apple officially brought Qi2 to iPhone 12.

Although Apple has not made any announcement about supporting the Qi2 standard on iPhone 12, users can also implicitly understand that the iPhone 12 supports the first Qi wireless charging standard and MagSafe before Qi2 technology is completed. good. A recent practical test has shown that the Anker Qi2 MagGo wireless charger when used with iPhone 12 has a charging speed equivalent to MagSafe.
