Abstract
An electronic device with a battery displays a label for indicating different power levels of the battery. The label comprises a plurality of columns. Each of the columns is capable of being illuminated. A number of the columns lighted correspond to a corresponding the power levels in a one-to-one relationship. The electronic device comprises a detection module, storage, an acquiring module, a check module, and a display module. The detection module detects the current voltage of the battery at regular intervals and stores the information in the storage. The acquiring module acquires a previous detected voltage from the storage. The check module checks whether the current voltage is a fluctuated voltage. The display displays the label with the numbers of the lighted columns corresponding to the power level which contains the previous detected voltage when the current voltage is a fluctuated voltage.
