The Google Nest Doorbell (battery) needs a recharge every few weeks to several months, depending on how often it records. Google estimates about six months at a few events a day, and as little as one month with heavy traffic. The wired models run on house power and do not need charging.
Quick Answer
Use the release tool to take the doorbell off its mount, plug the included USB-C cable into the doorbell and a USB power adapter, and let it charge fully before putting it back.
How to Charge a Nest Doorbell (Battery)
- In the Google Home app, check the battery level on the doorbell’s settings screen so you know how much it needs.
- Insert the release tool into the small hole at the bottom of the mount and push. The doorbell releases so you can lift it off.
- Bring the doorbell indoors, especially in cold weather. Batteries charge slowly or not at all near freezing.
- Connect the USB-C cable to the port on the doorbell and to a USB power adapter.
- Leave it until the light shows a full charge. From empty this can take several hours.
- Slide the doorbell back onto the mount until it clicks, and check that it comes back online in the app.

| Recorded events per day | Google’s rough estimate |
|---|---|
| 2 to 5 | About 6 months |

| 25 to 30 | About 1 month |

Troubleshooting
- If the doorbell will not charge, try another USB adapter and cable, and make sure it is at room temperature.
- If you lost the release tool, a replacement can be ordered, or check the Google support site for your model. Do not pry the doorbell off.
- If it does not reconnect after charging, restart it by holding the reset button below the USB port for about 5 seconds.
- If it drains quickly, lower the activity zones and event types in the Home app. See how to update Google Nest devices to get the latest firmware too.
