You press the Ring Battery Doorbell Plus, your phone buzzes with a notification, you pull up the live view, but the audio is dead. Either you can't hear the visitor, or they can't hear you. The mic on the doorbell seems to have stopped working entirely. Before you assume hardware failure, there are a few things to check that usually bring the audio back.
Quick fix: open the Ring app and start a live view. Tap the microphone icon on the bottom of the screen to make sure it's not muted (it should be blue, not gray). Also make sure your phone's volume is turned up and that the Ring app has permission to access your phone's microphone (Settings > Apps > Ring > Permissions on Android, or Settings > Ring > Microphone on iOS). Most of the time one of these two things is the culprit.
Why the Ring Battery Doorbell Plus Stops Hearing
The Battery Doorbell Plus runs on a removable battery pack and connects over 2.4 GHz WiFi only. A few common issues cause the mic to go quiet:
- Audio muted in the app: the mic and speaker both have independent mute toggles during live view, easy to accidentally toggle.
- Weak WiFi signal: the doorbell uses 2.4 GHz, which can get congested. If the RSSI in the Ring app is below -60, audio quality drops or cuts out.
- Cold weather battery sag: sustained temps below freezing reduce battery voltage, and the mic/speaker can become unresponsive until the battery warms up.
- Dirt or debris on the mic hole: the doorbell's tiny mic port (on the top edge of the faceplate) can get clogged with spider webs or dust.
- Firmware glitch: a pending update can mess with audio processing until the doorbell is rebooted.
Check the Live View Audio Controls
When you're in a live view, look at the bottom toolbar. The microphone icon is the second from the left. If it's gray, tap it to unmute. The speaker icon next to it controls what you hear from the doorbell, make sure that's blue too. These toggles reset every time you open a new live view, so check them each session.
If the doorbell rings but you answer from the notification, the same controls appear. It's easy to accidentally mute one side during a conversation, especially when you're holding the phone with one hand.
Power Cycle the Doorbell
Pop the faceplate off by pressing the release tab on the bottom (a small Phillips screwdriver might be needed if you have the anti-theft screws). Press the black button on the side to release the battery. Wait 30 seconds, then reinsert the battery. Push the faceplate back on until you hear it click.
This fully reboots the doorbell and clears any temporary audio states. Wait about a minute for the doorbell to reconnect to WiFi, you'll see the front light ring pulse white, then blue, then turn off. Test the audio with a live view.
Measure Your WiFi Signal Strength
Open the Ring app, tap the three lines in the top left, then Devices > select your Battery Doorbell Plus > Device Health. Look at the RSSI number, which ranges from 0 to -100. Anything below -60 (closer to -70) means the WiFi is weak, and audio can drop out.
The Battery Doorbell Plus only uses 2.4 GHz, which doesn't travel through walls as well as 5 GHz. If your router is far away or on the other side of a brick wall, consider a Ring Chime Pro (which acts as a WiFi extender) or move the router closer. Even a five-foot shift can improve the signal enough to fix audio.
Also check for congestion: 2.4 GHz channels get crowded in apartment buildings. If you see RSSI around -55 but still have audio problems, log into your router and switch to a less crowded channel (manual change, or let the router pick automatically).
Clean the Microphone Opening
The mic port is a tiny hole on the top edge of the doorbell faceplate, near the camera lens. Over time, dirt, spider webs, and pollen can block it. Use a soft, dry toothbrush or a can of compressed air (held a few inches away) to gently clear it. Don't stick anything sharp into the hole, or you might damage the internal mic membrane.
If you live in a dusty area or the doorbell faces a busy sidewalk, check this every couple of months. A blocked mic sounds like a dead mic. The problem often goes away immediately after cleaning.
Update the Firmware
Ring pushes firmware updates automatically, but sometimes a doorbell gets stuck on an older version. In the Ring app, go to Device Health > Firmware. The current version shows at the top. If there's an update available, it'll say "Update Available" with a button. Tap it and keep the doorbell within 10 feet of the router until the update finishes (typically 10 15 minutes).
If the app says "Up to date" but you're still having audio issues, try a manual reboot anyway. Some updates get applied but don't activate until the next reboot.
Factory Reset the Battery Doorbell Plus
If none of the above works, a full reset is worth trying. Remove the faceplate (security screws if installed). Find the small black setup button behind the faceplate, it's on the lower left side of the camera module. Press and hold it for 20 seconds. The front light ring will flash rapidly, then the doorbell reboots. Release the button after 20 seconds.
After the reset, the doorbell will announce "Welcome to Ring" and enter setup mode. Open the Ring app, remove the device (Device Settings > General Settings > Remove This Device), then set it up fresh. This clears all settings, including any audio configuration that may have gotten corrupted.
Battery Voltage and Cold Weather
The Battery Doorbell Plus's official operating range is -5°F to 122°F, but battery performance starts dropping well before that. In sustained sub-freezing weather, the lithium-ion battery's voltage sags, and the mic and speaker may become unresponsive. If you're experiencing audio problems only in cold morning hours, try bringing the battery indoors, letting it warm to room temperature, and reinserting it. If the audio works after that, the cold was the problem.
Consider buying a second battery to swap out. The battery lasts 4 6 months in normal use, but in cold climates that can drop to 2 3 months. Keep one warm inside and swap when the live view starts freezing or audio cuts out.
Test the Mic Directly
Start a live view and say something clearly toward the doorbell from 3 feet away. Then look at the live view on your phone, if you can hear your own voice played back through the phone's speaker, the doorbell's mic is working. If you hear nothing, and all the software checks are fine, the mic hardware may be defective.
Also test the speaker: while in a live view, tap the microphone icon to talk into your phone. If you can hear your own voice through the doorbell's speaker when standing close to it, the speaker works. If the audio is one-way only, the faulty component is the one that's silent.
Ring doesn't publish a user-replaceable mic assembly. If you've gone through everything and the mic still won't pick up sound, it's time to contact Ring support for a replacement under warranty. The Battery Doorbell Plus was released in 2023 so most units should still be covered.
