Apple already has a Smart Battery Case for iPhones which, when attached to the smartphone, starts charging the device. But it has a Lightning connector that needs to the attached to the phone for the charging function to work.
However, that could now become a thing of the past. Apple has filed a patent application (first reported by Apple Insider) and seems to be working on two-coil wireless charging technology for an iPhone battery case without the need or Lightning connector.
In the patent application, the company describes that the “battery case has first and second coils on opposing sides of a battery and has switching circuitry that is coupled between the first and second coils.”
It goes on to explain that the wireless charging case for the iPhone can use the built-in battery to power up a connected device using the second coil in an open state. Similarly, the case can also receive power for itself wirelessly in the open state.

This new patent from Apple related to the wireless charging iPhone battery case could mean that the rumors related to a “port-less” iPhone could come true in the coming years. Ming-Chi Kuo, a reliable source related to developments of Apple, claims that the Cupertino-giant could ditch Lightning port for a completely wireless iPhone by 2021.
The reason for Apple planning to adopt a completely wireless solution for the upcoming iPhones could be the European Union, which has voted to force smartphone manufacturers to choose a single common smartphone charging standard. It means that Apple will be forced to ditch the Lightning connector for USB-C, but it seems that instead of adopting USB-C, Apple has decided to go the port-less route with only wireless charging support.
