Discovered by AppleInsider, the patent suggests that through the press of one button, for example a button on a Bluetooth headset, not only would this power down the Bluetooth connection on the headset, but will also turn off Bluetooth for devices that are linked to it, such as an iPhone or MacBook.
It also suggests a power-saving mode, in which an iPhone or MacBook would enter in a power-saving mode whenever the Bluetooth has been turned on from an external headset. With our devices being more and more capable of handling multiple tasks and performing various activities, battery life has become quite an issue. However with most patents, we probably shouldn’t be holding our breaths here and waiting for it to realize.
