We have had one of the new Google Nest Battery Cameras since Sept. 2021, always plugged in with the optional 10-meter power cable. We also have a Nest Aware Plus subscription. Our camera always shows as "Live" in the Google Home app, it records 24/7, and the battery stays at 100%. If we unplug it, it shows as "Idle". I don't know whether the power adapter that comes with the charging cord is different from the power adapter that comes with the optional power cables, or whether that would explain the behavior you are seeing, or whether there's something else going on. Maybe the behavior you are seeing is because your cameras aren't "mounted" to the magnetic mount when you're charging them. The new Google Nest cameras released in the fall of 2021 have a new "Camera mount" setting under "Device information" in settings. You could try remounting one of the cameras and running an extension cord out to it temporarily to see whether you can view it live when its plugged in.
