Voltage.js

Small library providing information about the device's battery status

Usage

Get battery level

Voltage.getLevel(callback);

Is battery charging?

Voltage.isCharging(callback);

Get charging time

Voltage.getChargingTime(callback);

Get discharging time

Voltage.getDischargingTime(callback);

Quick example

The functions are asynchronous so you need to use a callback:

Voltage.getLevel(
    function (level) {
        console.log(level);
    }
);
