POWER CONSUMPTION REPORTING BY AN ACCESSORY OF AN ELECTRONIC DEVICE |
摘要 |
A method, system, and apparatus enables an electronic device in communication with an accessory to accurately report a remaining battery life when the accessory provides information relating to a power usage to the electronic device. In one embodiment, the accessory draws power from a battery of the electronic device, and the electronic device is able to more accurately estimate a remaining battery life by considering the power usage information provided from the accessory. The electronic device may thereafter indicate to a user the remaining battery life. In one alternative of this embodiment, the information relating to the power usage is in the form of a current consumption of the accessory. In another embodiment, the electronic device indicates a remaining battery life of a battery of an accessory. |
