Abstract
A delayed power-on function for an electronic device is disclosed. A charging unit charges a rechargeable battery with a pre-charge current when a voltage of the rechargeable battery is less than a voltage threshold value and with a current larger than the pre-charge current when the voltage of the rechargeable battery is greater than the voltage threshold value. A disabling unit can disable power-on when the voltage of the rechargeable battery is less than the voltage threshold value. A user may also be notified when power-on is disabled.
Claims19
An electronic device comprising:
- a rechargeable battery;
- a charging unit operable to:
- charge the rechargeable battery with a pre-charge current when a voltage of the rechargeable battery is less than a voltage threshold value;
- and
- charge the rechargeable battery with a current that is larger than the pre-charge current, when the voltage of the rechargeable battery is equal to or greater than the voltage threshold value;
- a disabling unit operable to disable power-on when the voltage of the rechargeable battery is less than the voltage threshold value;
- and
- a notifying unit operable to provide a power-on disabled notification, if the rechargeable battery is being charged with the pre-charge current and the pre-charge current is equal to or greater than a current threshold value.
A method for charging an electronic device, the method comprising:
- charging a rechargeable battery with a pre-charge current when a voltage of the rechargeable battery is less than a voltage threshold value;
- and
- charging the rechargeable battery with a current that is larger than the pre-charge current, when the voltage of the rechargeable battery is equal to or greater than the voltage threshold value;
- disabling power-on when the voltage of the rechargeable battery is less than the voltage threshold value;
- and
- providing a power-on disabled notification, if the rechargeable battery is being charged with the pre-charge current and the pre-charge current is equal to or greater than a current threshold value.
A non-transitory computer-readable medium for an electronic device, the computer-readable medium comprising program code for:
- charging a rechargeable battery with a pre-charge current when a voltage of the rechargeable battery is less than a voltage threshold value;
- and
- charging the rechargeable battery with a current that is larger than the pre-charge current, when the voltage of the rechargeable battery is equal to or greater than the voltage threshold value;
- disabling power-on when the voltage of the rechargeable battery is less than the voltage threshold value;
- and
- providing a power-on disabled notification, if the rechargeable battery is being charged with the pre-charge current and the pre-charge current is equal to or greater than a current threshold value.
