The iPhone 12 mini and iPhone 12 Pro Max will be available on Friday, but there are new changes in Apple's support document updated on November 2.
Simply put, the iPhone 12mini's maximum wireless charging power dropped to 12 watts, while the other three models were 15 watts.
That is to say, even if the original MagSafe magnetic suction charger and the quick charging head with more than 18 watts are used, the maximum charging power that the 12 Mini can receive can only touch 12 watts.
Despite some regrets, there are users
The supporting documents also updated more tips for using MagSafe, including that if a headset is connected to the lightning interface during wireless charging, the maximum charging power will be limited to 7.5 watts.
In addition, apple recommends that when using MagSafe's correct posture, first connect the charging head and get the power, and then attach the iPhone to ensure that the maximum charging power is configured safely. If you're attaching the iPhone before taking the power, you can remove the iPhone and wait 3 seconds for it to recharge.
