Ring doorbell low battery notification on phone

The ring doorbell provides a notification on the phone when it senses someone and when the bell is rung. But it needs a low battery notification that displays on the phone like the other notifications do. The last two times my battery was low I didn't know until the device stopped working. Having to open the app to check for this notification doesn't fly because I don't open the app unless I want to see who is at the door. A Low battery condition is too important to hide inside the app.
