A free program for Android, by Appsniff.
You can use the handy Pods Battery app to monitor the battery status of your AirPods, regardless of the device brand or model you have.
You can see the battery level of each AirPod, as well as the total amount of time that it has been connected to your device. Moreover, the app notifies you when your AirPods get connected, and it also lets you see the charging status of the AirPods whether they are in or out of the case.
It is important to note that the app will require you to turn on location permissions, as it will utilise Bluetooth API to retrieve the necessary AirPods data.
