This plugin provides an implementation of an old version of the Battery Status Events API.
It adds the following three window events:
cordova plugin add cordova-plugin-battery-status
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.
Windows Phone 7 does not provide native APIs to determine battery level, so the level property is unavailable. The isPlugged parameter is supported.
Windows Phone 8.1 does not support isPlugged parameter. The level parameter is supported.
Supported browsers are Chrome, Firefox and Opera.
window.addEventListener("batterystatus", onBatteryStatus, false);
function onBatteryStatus(info) {
// Handle the online event
console.log("Level: " + info.level + " isPlugged: " + info.isPlugged);
}
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.
Windows Phone 8.1 will fire batterycritical event regardless of plugged state as it is not supported.
window.addEventListener("batterycritical", onBatteryCritical, false);
function onBatteryCritical(info) {
// Handle the battery critical event
alert("Battery Level Critical " + info.level + "%\nRecharge Soon!");
}
Supported browsers are Chrome, Firefox and Opera.
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.
Windows Phone 8.1 will fire batterylow event regardless of plugged state as it is not supported.
window.addEventListener("batterylow", onBatteryLow, false);
function onBatteryLow(info) {
// Handle the battery low event
alert("Battery Level Low " + info.level + "%");
}
Supported browsers are Chrome, Firefox and Opera.
