To warn a user of a low battery:

window.addEventListener("batterylow", onBatteryLow, false); function onBatteryLow(info) { alert("Battery low! Current level " + info.level + "%"); }

In terms of using "minimal battery consumption" it really depends on how efficient your coding is, how efficiently you manage resources, etc.

A good thing to remember though is always use a custom build of Sencha Touch to ensure only the the classes your project uses are being loaded. See:
