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 controller 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.
Claims17
An electronic device, comprising:
- a display unit;
- a rechargeable battery;
- a controller that performs a predetermined function in response to at least one operation performed by a user;
- and
- 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, pre-charges the rechargeable battery with a second current larger than the first current if the voltage of the rechargeable battery is equal to or greater than the first value and less than a second value, and charges the rechargeable battery with a third current, which is larger than the second current if the voltage of the rechargeable battery is equal to or greater than the second value,
- wherein the controller disables the predetermined function and activates the display unit to display predetermined information in response to the at least one operation, if the at least one operation is detected when the charging unit is pre-charging the rechargeable battery with the second current.

An electronic device, comprising:
- a display unit;
- a rechargeable battery;
- an operation unit that receives input operations performed by a user;
- a wireless communication unit that performs a communication function;
- 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, pre-charges the rechargeable battery with a second current larger than the first current if the voltage of the rechargeable battery is equal to or greater than the first value and less than a second value, and charges the rechargeable battery with a third current, which is larger than the second current if the voltage of the rechargeable battery is equal to or greater than the second value;
- a system controller that disables the communication function and activates the display unit to display predetermined information in response to an operation performed by the user, if the operation is detected when the charging unit is pre-charging the rechargeable battery with the second current.
