If you have a device running iOS (iPhone, iPad, etc), The [iCloud](/components/device_tracker.icloud/) is gathering various details about your device including the battery level. To display it in the Frontend use a [template sensor](/components/sensor.template/). You can also the `battery` [sensor device class](/components/sensor/#device-class) to dynamically change the icon with the battery level.

While running the [Owntracks](/components/device_tracker.owntracks/) device tracker you can retrieve the battery level with a MQTT sensor. Replace username with your MQTT username (for the embedded MQTT it's simply homeassistant), and deviceid with the set Device ID in Owntracks.
