Battery charge time

Google Nest camera and doorbell battery charge time depends on several factors, including ambient temperature and the state and condition of the battery. The battery won't charge at temperatures below 0°C (32°F), and will charge slowly at temperatures near freezing.

Cold weather battery charging behaviour in Nest cameras and doorbells.

Nest Doorbell (battery)

Typical: It takes approximately 5 hours to fully charge the battery using a compatible 7.5 W AC adaptor (sold separately).

Important: To help prolong the life of your doorbell's battery, it will only charge to 75% if the doorbell is wired to the doorbell system. Before you install your doorbell, you can use the USB cable to charge the battery above 75%. However, after the doorbell is wired to the system, the battery will drop down to 75% and stay at that level or below.

Nest Cam (battery)

Typical: It takes approximately 5 hours to fully charge the battery using the provided 7.5 W AC adaptor and charging cable.
