Google is reportedly working on improving the Fast Pair user interface for true wireless earbuds, according to an APK teardown. The update is expected to bring more intuitive battery indicators within the Fast Pair notifications. This change aims to provide users with a clearer and more convenient way to monitor the battery levels of their earbuds and charging case during the pairing process. The improved UI could potentially reduce confusion and enhance the overall user experience when connecting and managing TWS earbuds with Android devices.
