Events (Battery Status)

This plugin provides an implementation of an old version of the Battery Status Events API.

It adds the following three window events:

  • batterystatus
  • batterycritical
  • batterylow

Installation

cordova plugin add org.apache.cordova.battery-status

batterystatus

This event fires when the percentage of battery charge changes by at least 1 percent, or if the device is plugged in or unplugged.

The battery status handler is passed an object that contains two properties:

  • level: The percentage of battery charge (0-100). (Number)

  • isPlugged: A boolean that indicates whether the device is plugged in. (Boolean)

Applications typically should use window.addEventListener to attach an event listener after the deviceready event fires.

Supported Platforms

  • Amazon Fire OS
  • iOS
  • Android
  • BlackBerry 10
  • Windows Phone 7 and 8
  • Tizen

Windows Phone 7 and 8 Quirks

Windows Phone 7 does not provide native APIs to determine battery level, so the level property is unavailable. The isPlugged parameter is supported.

Example

window.addEventListener("batterystatus", onBatteryStatus, false);

function onBatteryStatus(info) {
    // Handle the online event
    console.log("Level: " + info.level + " isPlugged: " + info.isPlugged);
}

batterycritical

The event fires when the percentage of battery charge has reached the critical battery threshold. The value is device-specific.

The batterycritical handler is passed an object that contains two properties:

  • level: The percentage of battery charge (0-100). (Number)

  • isPlugged: A boolean that indicates whether the device is plugged in. (Boolean)

Applications typically should use window.addEventListener to attach an event listener once the deviceready event fires.

Supported Platforms

  • Amazon Fire OS
  • iOS
  • Android
  • BlackBerry 10
  • Tizen

Example

window.addEventListener("batterycritical", onBatteryCritical, false);

function onBatteryCritical(info) {
    // Handle the battery critical event
    alert("Battery Level Critical " + info.level + "%\nRecharge Soon!");
}

batterylow

The event fires when the percentage of battery charge has reached the low battery threshold, device-specific value.

The batterylow handler is passed an object that contains two properties:

  • level: The percentage of battery charge (0-100). (Number)

  • isPlugged: A boolean that indicates whether the device is plugged in. (Boolean)

Applications typically should use window.addEventListener to attach an event listener once the deviceready event fires.

Supported Platforms

  • Amazon Fire OS
  • iOS
  • Android
  • BlackBerry 10
  • Tizen

Example

window.addEventListener("batterylow", onBatteryLow, false);

function onBatteryLow(info) {
    // Handle the battery low event
    alert("Battery Level Low " + info.level + "%");
}
