Surprise! Your iPhone 12 got an upgrade to 15W magnetic charging with Qi2

Macworld tests show faster MagSafe speeds after iOS 17.4.

A series of tests and feedback from Macworld readers prove that the iPhone 12 now works at full 15W wireless charging speed when magnetically connected to a non-MagSafe Qi2 charger. A Macworld reader first alerted us to the change after his Belkin BoostCharge Pro 2-in-1 Magnetic Wireless Charging Pad with Qi2 filled up his phone faster and displayed the MagSafe/Qi2 animation. While the iPhone 12 Pro is equipped with MagSafe, which offers a similar alignment and efficiency improvement over traditional Qi charging, it was designed before the Qi2 standard was finalized and introduced.
