Can you imagine never having to put you iPad on the charger again. Or even having to carrying around that extra battery pack. Wireless charging efficiency relies on close proximity between the transmitting and receiving induction coils. Apple’s existing Smart Cover magnet system uses magnets with alternating polarities to ensure a precise alignment of cover to iPad, a pairing that would help optimize the charging system.
The system would automatically charge the iPad when the cover is closed, with the cover itself being charged conventionally by plugging it into a power source via USB, although Apple notes that solar cells could also be incorporated into the cover.
Apple has had a long-standing interest in various forms of wireless charging, but the technology has yet to make its way into the company’s mobile devices. Just last week, a report suggested that Apple may be introducing wireless charging the iPhone as soon as this year, although it seems like a relatively unlikely addition for the iPhone 5S.
