Apple’s Latest Published Patent Details 2-Way Charging Feature at Great Length

We expected Apple to usher in a new technology called ‘Hybrid Wireless Charging System.’ Our expectation was mostly fueled by Kuo’s report that predicted Hybrid Charging on iPhone 11. However, Kuo soon retreated and ate his words in September. Today, the US Patent & Trademark Office has published a patent from Apple that talks in length about reverse wireless charging on devices like iPhone, iPad, and MacBook.

We have seen reversible charging on a lot of Android smartphones. However, Apple’s reversible charging is wireless in nature and allows you to transmit the charge to a second electronic device.  In order for this to work, Apple will bake in a hybrid receiver/transmitter coil and other arrangements that will help align the secondary device with the wireless charger.

The hybrid charging technology will allow you to charge other electronic devices with the help of a charging pad. For instance, you can keep an iPhone on MacBook wireless charging pad and charge your phone on the go. With the same arrangement, you can also charge Apple Watch or AirPods. Apple mentions in its patent filing that portable electronic device can be a consumer electronic device like smartphones, tablet, and others.

As you can see in the above diagram, the secondary device is typically positioned on the charging surface. Needless to say, the secondary device will be able to receive the charge from the primary device and the transfer of power takes via the surface of the charging pad. Apple’s patent was filed back in Q2 2019 and was published today by the U.S Patent Office. As always, we are in no position to predict as to when we can see Apple baking in the hybrid wireless charging feature on its devices. Hopefully, we will be able to see the same next year.
