This is an event that fires when a PhoneGap application detects the battery has reached the critical level threshold.
window.addEventListener("batterycritical", yourCallbackFunction, false);
This event that fires when a PhoneGap application detects the percentage of battery has reached the critical battery threshold. This value is device specific.
The batterycritical handler will be called with an object that contains two properties:
Typically, you will want to attach an event listener with window.addEventListener
once you receive the PhoneGap ‘deviceready’ event.
window.addEventListener("batterycritical", onBatteryCritical, false); function onBatteryCritical(info) { // Handle the battery critical event alert("Battery Level Critical " + info.level + "%\nRecharge Soon!"); }
