Doorbell won’t charge even while hardwired

If my Doorbell won’t charge even while hardwired, what is my next step?

I used to be fine and at 100%, but just found it at 30% and declining.

Has the internal battery gone bad?

Hi @jpetrovic. Would you mind sharing what model Ring Doorbell you’re referencing? It would also be helpful to share what transformer you are using as well as its voltage rating. As a general tip, you can always reset your doorbell and reconnect it to wifi. To reset your doorbell, press and hold the setup button for 20 seconds, then release. This should cause your doorbell to reflect the corrected power source once it finishes a quick update. I hope this helps!
