It is expected that background detections on Android 8+ will typically take ~15 minutes. Thus blog post explains the tech limitations:

Two alternatives for faster detections in the background with the library:

  1. Use a foreground service: https://altbeacon.github.io/android-beacon-library/foreground-service.html
  2. Use the intent scan strategy: https://github.com/AltBeacon/android-beacon-library/pull/1030
