Apple had seen fit to release the sixth developer beta of its upcoming iOS 12.2 firmware update. While it might have been too early to ask what the new build had in store, now we are seeing some details regarding the new additions. The sixth developer beta of iOS 12.2 brings a bevy of changes to the component responsible for charging the device wirelessly. Furthermore, it also features the code responsible for the identification of two devices being charged on the same mat. Could this possibly mean that Apple’s AirPower mat is closing in to be launched?

Apple’s AirPower mat can charge three devices simultaneously and the device with the biggest display will show the status of all devices. It also presents 3D animations of the devices being charged on the screen when the session begins.
