Apple has filed for a patent (number 20200328605) for the MagSafe technology introduced with iPhone 12 mini, iPhone 12, iPhone 12 Pro, and iPhone 12 Pro Max this week.
MagSafe is designed, in Apple’s words, to “improve wireless charging for a better, more efficient experience, and introduces an ecosystem of easy-to-attach accessories that beautifully complement iPhone 12 modes.” It features an array of magnets around a wireless charging coil, optimized for alignment and efficiency.
MagSafe chargers efficiently provide up to 15W of power, while still accommodating existing Qi-enabled devices. Charging solutions include the MagSafe Charger and MagSafe Duo Charger for use with iPhone and Apple Watch, as well as new silicone, leather, and clear cases that snap onto the back of iPhone, and a leather wallet. MagSafe accessories are also in the works from third-party manufacturers.
Here’s the summary of the new patent filing: “An accessory device may include a receptacle used to receive and carry an electronic device. Further, the accessory device may include a cover that is pivotally coupled to the receptacle. The cover is designed to protect a front surface of the electronic device, including a cover glass. The accessory device may further include a power supply (such as a battery) that is located on the cover.
“The power supply is designed to provide power to the electronic device, and subsequently charge a battery of the electronic device. The power supply can also provide power to different devices. In this regard, the accessory device may include an inductive charging coil that can inductively charge a battery of a device located on the accessory device. The inductive charging coil can be integrated into the receptacle or the cover.”
