Hello Stephanie,
Welcome to Microsoft Community.
After fully reading everything you've posted, can I assume that you're just wondering why the Surface Earbuds don't have any battery percentage display?
If you need to see how much power is left, then you need to use the Surface app, because nowhere on the Surface Earbuds will the percentage of power be displayed:

Or maybe I didn't fully understand what you were trying to say? If my understanding is incorrect, could you provide some screenshot information so that I can understand your question more clearly?
