Dead batteries

I have 2 ring 2 doorbell devices and a camera device. The camera battery on the same network is fine but the two bell devices need to be charged more than once a week. I charged on saturday afternoon to 100 percent and by today monday morning they are around 65 percent. Gone through the videos and articles and dont see a fix. This is a new problem. System installed in November and all worked fine until about two weeks ago. As far as I know nothing has changed. After I charged them on sunday I tuned off all operations on the device and the battery is still running down. Thanks in advance.
