The event fires when the battery has reached the low level threshold.
window.addEventListener("batterylow", yourCallbackFunction, false);
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 document.addEventListener
to attach an event listener once the deviceready
event fires.
window.addEventListener("batterylow", onBatteryLow, false); function onBatteryLow(info) { // Handle the battery low event alert("Battery Level Low " + info.level + "%"); }
