Electronic device and method for displaying remaining battery capacity of the electronic device

A computer-implemented method for displaying remaining capacity of an electronic device being executed by at least one processor of the electronic device, the method comprising:

• recording a first remaining capacity of a battery of the electronic device before turning off the electronic device;
• recording a second remaining capacity of the battery after turning on the electronic device;
• determining whether a first difference value between the first remaining capacity and the second remaining capacity is greater than a predetermined value;
• calculating the remaining capacity of the battery for predetermined times during a preset interval to obtain a plurality of calculated remaining capacity if the first difference value is greater than the predetermined value;
• determining whether a second difference value is greater than the predetermined value, wherein the second difference value is between each calculated remaining capacity and the first remaining capacity;
• and
• displaying the latest calculated remaining capacity during the preset interval on the display device if the second difference value is greater than the predetermined value, wherein it is determined that the battery of the electronic device is recharging or voltage impulse of the electronic device is abnormal when the first difference value is greater than the predetermined value.

A non-transitory storage medium having stored thereon instructions that, when executed by a processor of an electronic device, causes the processor to perform a displaying method using the electronic device, the method comprising:

• recording a first remaining capacity of a battery of the electronic device before turning off the electronic device;
• recording a second remaining capacity of the battery after turning on the electronic device;
• determining whether a first difference value between the first remaining capacity and the second remaining capacity is greater than a predetermined value;
• calculating the remaining capacity of the battery for predetermined times during a preset interval to obtain a plurality of calculated remaining capacity if the first difference value is greater than the predetermined value;
• determining whether a second difference value is greater than the predetermined value, wherein the second difference value is between each calculated remaining capacity and the first remaining capacity;
• and
• displaying the latest calculated remaining capacity during the preset interval on the display device if the second difference value is greater than the predetermined value, wherein it is determined that the battery of the electronic device is recharging or voltage impulse of the electronic device is abnormal when the first difference value is greater than the predetermined value.
