According to mobile app, my Ring Doorbell 3 is hardwired but the battery is down to 30%.
According to the webpage, my Ring Doorbell 3 is running on battery and is down to 37%.
I’ve gone through the process of resetting the device and running the setup again (and also checking that there’s voltage appearing at the end of the power supply cable) but it makes no difference.
This glorified doorbell is becoming more trouble than it’s worth.
