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.
Claims8
An electronic device, comprising:
- a rechargeable battery;
- a wireless communication unit that performs communication with another device;
- a controller that performs a predetermined function in response to at least one operation performed by a user;
- a charging unit that pre-charges the rechargeable battery with a first current if a voltage of the rechargeable battery is less than a first value, and quickly charges the rechargeable battery with a second current, which is larger than the first current, if the voltage of the rechargeable battery is equal to or greater than the first value;
- a disabling unit that disables the predetermined function if the rechargeable battery is being charged with the first current;
- and
- a notification unit that, in response to the at least one operation being detected, notifies the user that the rechargeable battery is being recharged if the at least one operation is detected when the rechargeable battery is being charged with the first current.
A power-on status notification method in an electronic device, the electronic device including a rechargeable battery, a wireless communication unit that becomes operable in response to a supply of power to perform communication with another communication device, and an operation unit that accepts operation done by a user, said method comprising:
- detecting at least one operation by a user, the at least one operation corresponding to a predetermined function to be performed by the electronic device;
- a charging step of pre-charging the rechargeable battery with a first current if a voltage of the rechargeable battery is less than a first value, and quickly charging the rechargeable battery with a second current, which is larger than the first current, if the voltage of the rechargeable battery is equal to or greater than the first value;
- disabling the predetermined function if the rechargeable battery is being charged with the first current;
- and
- notifying the user, in response to detecting the at least one operation, that the rechargeable battery is being recharged if the predetermined operation is detected when the rechargeable battery is being charged with the first current.
