Abstract

A method of controlling screen brightness of an electronic device includes detecting the remaining capacity of a battery installed on an electronic device, and controlling screen brightness of the electronic device according to the remaining capacity of the battery. Power consumption of the electronic device can be reduced according to the remaining capacity of the battery; therefore, battery run time of the electronic device can be increased.

Claims

1. A method of controlling screen brightness of an electronic device according to a status of a battery, the method comprising the following steps:

a) detecting remaining capacity of a battery installed on an electronic device; and

b) controlling screen brightness of the electronic device according to the remaining capacity of the battery.

2. The method of claim 1 further comprising detecting type of power supply of the electronic device.

3. The method of claim 1 further comprising generating remaining utilization time of the battery according to the remaining capacity of the battery wherein step (b) is controlling the screen brightness of the electronic device according to the remaining utilization time of the battery.

4. The method of claim 1 wherein step (a) is a basic input/output system (BIOS) detecting the remaining capacity of the battery installed on the electronic device.

5. The method of claim 1 further comprising generating a screen brightness value according to the remaining capacity of the battery wherein step (b) is controlling the screen brightness of the electronic device according to the screen brightness value.
