The battery life of a video doorbell can vary depending on several factors, including the specific model and usage patterns. Typically, battery-powered video doorbells are designed to last anywhere from two to six months on a single charge. However, it's important to note that factors such as the frequency of motion detections, the number of times the two-way communication is used, and extreme weather conditions can all affect the battery life. To ensure your smart doorbell remains operational, regularly check the battery status through the accompanying app and be prepared to recharge or replace the battery as needed.
