Abstract: A method of controlling charging of a wireless headphone device includes estimating a usage time value that corresponds to an anticipated future occurrence of usage of the wireless headphone device and estimating a resume time value that corresponds to a time for charging to commence to allow for completion of charging from a first predetermined state of charge value to a second predetermined state of charge value by the usage time value. The method also includes determining that the wireless headphone device has been placed in a charging case. A battery of the wireless headphone device is charged to the first predetermined state of charge value and then enters a deactivated mode, wherein the charging case is configured to return the wireless headphone device to an activated mode according to the resume time value.

Abstract: A method of controlling charging of an electronic device includes estimating a usage time value that corresponds to an anticipated future occurrence of usage of the electronic device; and estimating a resume time value that corresponds to a time for charging to commence to allow for completion of charging from a first predetermined state of charge value to a second predetermined state of charge value by the usage time value. The method also includes charging a battery of the electronic device using electrical power supplied by a charging device until a current state of charge of the battery reaches the first predetermined state of charge value, entering, by the electronic device, a deactivated mode after the current state of charge reaches the first predetermined state of charge value, and causing the electronic device to return to the activated mode according to the resume time value.

Abstract: An electronic device can include a power system including a battery and one or more processors programmed to: detect that the electronic device has been connected to a power source, predict using prior usage data of the electronic device whether battery usage between an expected time of disconnection from the power source and a next expected time of connection to the power source exceeds a threshold, and if the predicted battery usage between an expected time of disconnection from the power source and a next expected time of connection to the power source does not exceed the threshold, charge the battery to a state of charge less than the full state of charge of the battery.
