The battery status is displayed with an interval size of 10% (Full | 95% | 85% ...), because the devices only send their battery state with this accuracy. Also the case of the AirPods misses a Bluetooth transmitter. Therefore, the battery level of the case is only displayed when at least one AirPod is inserted in the case.
The app uses Bluetooth Low Energy (BLE) interface. The API for Bluetooth LE only works with Location Permission, because the beacons for indoor navigation also uses Bluetooth LE.
The only known way to customize AirPods and change the double-tap functionality is connecting with an iPhone or Macbook. After then you can use the changed the double-tap functionality with Android.
