Hi there, @Firestorm457! Check out our Community post for tips on optimizing battery usage and avoiding battery drain factors. As the Doorbell in question experiences less usage, check the RSSI, and wifi signal interference can cause battery drain as well. Try charging the Video Doorbell for several hours using the provide micro usb, then keeping the Doorbell inside near the router to monitor the battery level change over a day or so.
If the battery drain persists, please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support.
